Any `.md` in the agent dir gets loaded — including accidental files like `CLAUDE.md`. + +7. **SDK regeneration is the bridge.** Engine API changes don't affect the frontend directly — they affect the generated SDK types. Always regenerate after engine changes. + +8. **The desktop app is remarkably resilient.** Because the frontend connects via HTTP/JSON, most engine refactors (Effect migration, branded IDs, server factory) have zero impact. Only API surface changes matter. + +9. **Their Tauri wrapper simplified dramatically.** `lib.rs` went from 236 to ~100 lines — always spawn local sidecar, credentials before health check. Compare with Orbit's `opencode/process.rs` for simplification opportunities. + +10. **Test the sidecar binary, not just the dev server.** `bun dev serve` and the compiled `orbit-server` binary can behave differently. Always rebuild and test. + +### General + +- **Don't copy files blindly.** Apply changes surgically — the fork has modifications upstream doesn't have (Orbit renames, config paths, removed prompts). +- **One commit per phase.** Makes it easy to bisect if something breaks. +- **Run typecheck often.** TypeScript catches most integration issues before runtime. +- **The diff analysis document is the most valuable artifact.** It takes time to write but saves days of confusion.

NEW FILES (24 files) + +### 1A. Account System (5 files) — Entirely new module + +Cloud account management with OAuth device flow, org switching, and remote config fetching. Built entirely with Effect.ts. + +| # | File | What it does | PICK? | +| --- | ---------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----- | +| 1 | `src/account/account.sql.ts` | Drizzle ORM tables: `AccountTable` (OAuth tokens, email, server URL), `AccountStateTable` (active account + org context), legacy `ControlAccountTable` | | +| 2 | `src/account/schema.ts` | Effect Schema branded types: `AccountID`, `OrgID`, `AccessToken`, `RefreshToken`, `DeviceCode`, `UserCode`. Domain models: `Account`, `Org`, `Login`. OAuth poll result union (6 tagged classes). Error types. | | +| 3 | `src/account/repo.ts` | Data access layer with Effect Layers. CRUD: `active()`, `list()`, `remove()`, `use()`, `persistToken()`, `persistAccount()`. Uses Drizzle transactions. Single-row `AccountStateTable` for active context. | | +| 4 | `src/account/service.ts` | High-level service: token refresh via `/auth/device/token`, OAuth login flow (`login()` → `poll()`), org/config fetching with bearer tokens, HTTP retry (2x exponential backoff + jitter). | | +| 5 | `src/account/index.ts` | Public API: `Account.active()` (sync), `Account.config(accountID, orgID)` (async), `Account.token(accountID)` (async, auto-refreshes). Wraps Effect with `runSync`/`runPromise`. | | + +**Context:** This is their cloud account system (likely for opencode.ai hosted service). If you don't have a cloud offering, you probably don't need this. + +--- + +### 1B. Auth Service — Effect refactor (1 file) + +| # | File | What it does | PICK? | +| --- | --------------------- | ---------------------------------------------------------------------- | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------- | --- | +| 6 | `src/auth/service.ts` | Generic credential storage as Effect service. Union type `Info = Oauth | Api | WellKnown`. Reads/writes `~/.opencode/data/auth.json`. CRUD: `get()`, `all()`, `set()`, `remove()`. Normalizes keys (strips trailing slashes). | | + +**Context:** This replaces the old imperative auth storage with an Effect-based service. The old `auth/index.ts` now wraps this service. If you're using Effect, this is cleaner. If not, the old pattern still works. + +--- + +### 1C. Provider Auth Service — Effect-based (1 file) + +| # | File | What it does | PICK? | +| --- | ------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----- | +| 7 | `src/provider/auth-service.ts` | Effect service for provider OAuth + API key management. Loads plugin auth methods indexed by `ProviderID`. Tracks pending OAuth in memory. Methods: `methods()`, `authorize()`, `callback()`, `api()`. Uses `InstanceState` for per-instance plugin cache. | | + +**Context:** This is the Effect-ified version of what was previously in `provider/auth.ts`. The old file now delegates to this service via `runPromise()`. + +--- + +### 1D. CLI Account Commands (2 files) + +| # | File | What it does | PICK? | +| --- | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ----- | +| 8 | `src/cli/cmd/account.ts` | yargs commands: `LoginCommand` (device OAuth flow), `LogoutCommand`, `SwitchCommand` (org picker), `OrgsCommand` (list accounts), `ConsoleCommand` (parent grouping). Uses clack prompts + Effect.gen. | | +| 9 | `src/cli/effect/prompt.ts` | Effect wrappers around `@clack/prompts`: `intro()`, `outro()`, `log.info()`, `select()` (returns `Option`), `spinner()`. | | + +**Context:** CLI commands for cloud account management. Only needed if you bring in the account system. + +--- + +### 1E. Branded ID Schemas (9 files) — Type safety foundation + +All follow the same pattern: `Schema.String.pipe(Schema.brand("XxxID"), withStatics({ make(), ascending/descending(), zod }))`. The `withStatics` helper attaches static factory methods to Effect schemas. + +| # | File | Branded Type | Statics | PICK? | +| --- | ----------------------------- | ---------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----- | +| 10 | `src/util/schema.ts` | _(helper)_ | `withStatics(methods)` — HOF to attach statics to any Effect schema. **Foundation for ALL branded IDs.** | | +| 11 | `src/session/schema.ts` | `SessionID`, `MessageID`, `PartID` | `.make()`, `.descending()` (SessionID), `.ascending()` (Message/Part), `.zod` | | +| 12 | `src/provider/schema.ts` | `ProviderID`, `ModelID` | `.make()`, `.zod`, well-known constants: `.anthropic`, `.openai`, `.google`, `.googleVertex`, `.githubCopilot`, `.amazonBedrock`, `.azure`, `.openrouter`, `.mistral`, `.opencode` | | +| 13 | `src/control-plane/schema.ts` | `WorkspaceID` | `.make()`, `.ascending()`, `.zod` | | +| 14 | `src/permission/schema.ts` | `PermissionID` | `.make()`, `.ascending()`, `.zod` | | +| 15 | `src/project/schema.ts` | `ProjectID` | `.make()`, `.global` (returns "global"), `.zod` | | +| 16 | `src/pty/schema.ts` | `PtyID` | `.make()`, `.ascending()`, `.zod` | | +| 17 | `src/question/schema.ts` | `QuestionID` | `.make()`, `.ascending()`, `.zod` | | +| 18 | `src/tool/schema.ts` | `ToolID` | `.make()`, `.ascending()`, `.zod` | | + +**Context:** These branded IDs ripple through ~25 modified files. If you adopt them, you'll need to update every file that creates/passes IDs. If you skip them, the modified files with BRANDED_ID changes can be ignored too. It's all-or-nothing for the typing benefits. + +--- + +### 1F. Effect Utilities (4 files) + +| # | File | What it does | PICK? | +| --- | -------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----- | +| 19 | `src/effect/runtime.ts` | Singleton `ManagedRuntime` merging `AccountService.defaultLayer` + `AuthService.defaultLayer`. Used globally for running all Effects. | | +| 20 | `src/util/effect-http-client.ts` | HTTP client with transient error retry: 2x exponential backoff (200ms base) + jitter. Wraps Effect `HttpClient`. | | +| 21 | `src/util/effect-zod.ts` | AST-based converter from Effect Schema → Zod. Walks schema AST recursively (String, Number, Boolean, Literal, Union, Objects, Arrays). Enables branded types to expose `.zod` for Hono validators. | | +| 22 | `src/util/instance-state.ts` | Scoped cache for per-instance state (plugins, config). `get/has/invalidate/dispose()`. Auto-cleanup on scope exit. Used by provider auth for plugin caching. | | + +**Context:** These are foundational for the Effect migration. `effect-zod.ts` is particularly important — it's the bridge that lets Effect schemas work with Zod validators in HTTP routes. `instance-state.ts` replaces ad-hoc caching patterns. + +--- + +### 1G. Standalone Utilities (2 files) + +| # | File | What it does | PICK? | +| --- | ----------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----- | +| 23 | `src/util/data-url.ts` | `decodeDataUrl(url)` — parses `data:[type];[encoding],`. Handles base64 and URL-encoded. Returns decoded string. 9 lines. | | +| 24 | `src/file/protected.ts` | Platform-specific protected paths that should never be watched/scanned. macOS: Music, Pictures, Movies, Downloads, Desktop, Documents, iCloud, TCC paths (Safari, Mail, AddressBook). Windows: AppData, OneDrive, Downloads. Prevents TCC permission prompts + perf issues. | | + +**Context:** `data-url.ts` is used by `session/prompt.ts` for text attachments. `file/protected.ts` is a good defensive addition for file watchers. + +--- + +## 2. MODIFIED FILES — By Theme + +### 2A. Bun Removal (12 files) — Replacing `$\`...\``with portable`Process.run()` + +They're decoupling from Bun's shell syntax (`import { $ } from "bun"`) and using Node-compatible APIs instead. Also changed `pathToFileURL` from `bun` to `url` module. + +| # | File | What changed | Impact | PICK? | +| --- | ------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------ | ----- | +| 1 | `src/util/process.ts` | Removed `import { $ } from "bun"`. All git/shell calls → `Process.run()` / `Process.text()`. Added `TextResult` interface, `lines()` helper, `windowsHide` option. | **HIGH** — Central process execution | | +| 2 | `src/snapshot/index.ts` | Removed Bun `$` syntax. All git snapshot commands → `Process.run()` / `Process.text()`. Added `args()` helper for git command building. ~100 net lines changed. | **HIGH** — Snapshot system | | +| 3 | `src/worktree/index.ts` | Removed `$` syntax. Git worktree commands → `git()` wrapper / `Process.run()`. Added `ProjectID` branded type to `runStartScripts`. | **HIGH** — Worktree system | | +| 4 | `src/tool/bash.ts` | Removed `import { $ } from "bun"`. Replaced with `fs.realpath()` + native Node APIs. Added `windowsHide: process.platform === "win32"`. | **MEDIUM** — Bash tool | | +| 5 | `src/cli/cmd/github.ts` | Removed `$` syntax. Added `gitText`, `gitRun`, `gitStatus`, `commitChanges` helpers. Error handling `$.ShellError` → `Process.RunFailedError`. | **HIGH** — GitHub integration | | +| 6 | `src/cli/cmd/pr.ts` | Removed `$` syntax → `Process.run()` / `Process.text()`. `.exitCode` → `.code`, `.text()` → `.text`. | **MEDIUM** | | +| 7 | `src/cli/cmd/uninstall.ts` | Removed `$` syntax → `Process.run()`. `.exitCode` → `.code`. | **MEDIUM** | | +| 8 | `src/cli/cmd/run.ts` | `pathToFileURL` from `bun` → `url` module. `Server.App()` → `Server.Default()`. | **LOW** | | +| 9 | `src/cli/cmd/tui/clipboard.ts` | Removed `$` syntax → `Process.run()`. Added `fs.rm()` instead of shell `rm`. | **HIGH** — Clipboard | | +| 10 | `src/cli/cmd/tui/worker.ts` | `Server.App()` → `Server.Default()`. | **LOW** | | +| 11 | `src/bun/index.ts` | Bun-specific cleanup | **LOW** | | +| 12 | `src/bun/registry.ts` | `Process.text()` for registry reads. `stdout`/`stderr` read before `await proc.exited`. | **MEDIUM** | | + +**Context:** If you're still running on Bun (which you are), these changes aren't strictly necessary. But they make the code more portable and remove dependency on Bun's non-standard shell API. + +--- + +### 2B.

All functions delegate to service. Exports `OAUTH_DUMMY_KEY`. | **HIGH** — Auth API surface | | +| 2 | `src/provider/auth.ts` | Gutted ~90 lines of imperative state management. Now delegates to `ProviderAuthService` (Effect) via `runPromise()`. All error types via `export import`. | **HIGH** — Provider auth API | | +| 3 | `src/provider/provider.ts` | Added `DEFAULT_CHUNK_TIMEOUT` (120s). `wrapSSE()` for SSE read timeouts with AbortController. `shouldUseCopilotResponsesApi()` excludes gpt-5-mini. Branded ID types for provider/model params. | **MEDIUM** — SSE timeout is a good bug fix | | +| 4 | `src/server/server.ts` | `App` singleton → `createApp(opts: { cors?: string[] })` factory. `Default = lazy(() => createApp({}))`. Workspace ID parsing now uses `WorkspaceID.make()`. Major re-indentation. ~450 net lines changed. | **HIGH** — Server initialization | | +| 5 | `src/config/config.ts` | 64 lines changed — likely Effect integration for config loading | **MEDIUM** | | +| 6 | `src/index.ts` | 6 lines — updated exports for new modules | **LOW** | | +| 7 | `src/installation/index.ts` | 118 lines changed — installation flow updates, likely Effect/branded types | **MEDIUM** | | +| 8 | `src/share/share-next.ts` | 102 lines changed — share API updates, auth header logic, endpoint path changes (`/api/share/` → `/api/shares/`) | **MEDIUM** | | + +--- + +### 2C. Branded ID Adoption (25+ files) — `Identifier.schema()` → typed IDs + +These are the ripple effects of the branded ID schemas. Each file replaces raw `Identifier.ascending("prefix")` calls with typed equivalents like `SessionID.descending()`, `MessageID.ascending()`, etc. + +| # | File | Impact | Notes | PICK? | +| --- | ---------------------------- | ---------- | ---------------------------------------------------------------------------------------------------------- | ----- | +| 1 | `src/session/index.ts` | **HIGH** | 100+ replacements. Added `workspaceID` param to `createNext()`. Fork preserves workspace context. | | +| 2 | `src/session/message-v2.ts` | **MEDIUM** | 10+ replacements. Added `ModelID`, `ProviderID` to type annotations. New DB imports for pagination. | | +| 3 | `src/session/prompt.ts` | **HIGH** | Message/part ID generation now typed.

account services +- `ProviderAuthService` intentionally NOT included here -- it creates a separate `ManagedRuntime` in `provider/auth.ts` to avoid circular imports (`runtime.ts` -> `auth-service.ts`

Our fork currently does. If this causes stale provider instances after changing API keys, we may need to re-add it in the wrapper or emit a bus event. +- **Error propagation:** Errors are now wrapped in `AuthServiceError` before being thrown. Code that catches specific error types may need updating if it inspects error shapes. + +### Database Schema Changes + +- **Account tables added:** `account`, `account_state` tables (if porting account system). Requires running the `20260228203230_blue_harpoon` migration. + +### Impact on Desktop App Frontend + +- **None.** The HTTP API responses are unchanged.

LSP Server Refactor + +### What it fixes + +Large refactor replacing `bun:shell` (`$`) usage with `Process.run()` calls throughout the LSP server. Also replaces `Bun.resolve()` with portable `Module.resolve()` from `@opencode-ai/util/module`, and replaces `$\`chmod +x\``with`fs.chmod(bin, 0o755)`. + +### Current state in our fork + +Uses `$` (bun shell), `Bun.resolve()`, and shell commands for chmod throughout `lsp/server.ts`. + +### Upstream change + +- `spawn` import renamed to `launch`, wrapped with `windowsHide: true` +- All `$\`...\``calls replaced with`Process.run()`or`Process.text()` +- All `Bun.resolve()` calls replaced with `Module.resolve()` (from `@opencode-ai/util/module`) +- All `$\`chmod +x\``replaced with`fs.chmod(bin, 0o755)` +- All `$\`curl ...\``replaced with native`fetch()`+`Filesystem.writeStream()` +- JDTLS: improved Gradle monorepo root detection with `NearestRoot` exclusions +- JDTLS: `ls` command replaced with `fs.readdir()` + regex filter +- Kotlin LS: download via `fetch()` instead of `curl` +- Java version check: `$\`java -version\``to`Process.run()` + +### Files changed + +| File | Change | +| ------------------- | ---------------------------------------------------- | +| `src/lsp/server.ts` | ~200 lines changed across 15+ LSP server definitions | + +### New dependency + +- `@opencode-ai/util/module` -- `Module.resolve()` function.

MCP OAuth State Fix + +### What it fixes + +MCP OAuth flow fails on first connect because `state()` was called before `startAuth()` saved the state. The SDK calls `state()` as a generator (to create new state), not just a reader. + +### Current state in our fork + +`state()` throws `Error("No OAuth state saved for MCP server: ...")` if no state exists. + +### Upstream change + +Instead of throwing, `state()` now generates a new random hex state string (32 bytes), persists it via `McpAuth.updateOAuthState()`, and returns it.

Skills in System Prompt + +### What it adds + +Skills are now included in the system prompt (not just the tool description). This gives the LLM better context about available skills before it decides to invoke the skill tool. + +### Current state in our fork + +Skills are only described in the skill tool's description parameter. The system prompt has no mention of skills. + +### Upstream change + +**`src/session/system.ts`**: + +- New `SystemPrompt.skills(agent)` async function +- Checks if skill permission is not denied for the agent +- Calls `Skill.available(agent)` to get filtered list +- Returns XML-formatted skill descriptions using `Skill.fmt(list, { verbose: true })` + +**`src/skill/skill.ts`**: + +- New `Skill.available(agent?)` -- filters skills by agent permission +- New `Skill.fmt(list, { verbose })` -- formats skill list as XML (verbose) or Markdown (compact) + +**`src/tool/skill.ts`**: + +- Refactored to use `Skill.available()` and `Skill.fmt(list, { verbose: false })` instead of inline formatting +- Fixes `.then((x) => Object.keys(x).join(", "))` to `.then((x) => x.map((skill) => skill.name).join(", "))` + +### Files changed + +| File | Change | +| ----------------------- | ------------------------------------------------------------ | +| `src/session/system.ts` | Add `SystemPrompt.skills()` | +| `src/skill/skill.ts` | Add `available()` and `fmt()` | +| `src/tool/skill.ts` | Refactor to use shared `Skill.available()` and `Skill.fmt()` | + +### Rename needed + +None (skills are user-defined, not branded). + +### Desktop app impact + +None -- system prompt is server-side only. + +### Depends on + +Nothing.

Previously returned all messages; now supports `?limit=N&before=` query parameters with `Link` header and `X-Next-Cursor` response header for traversal. + +### Current state in our fork + +Returns all messages with optional `?limit=N` (simple truncation, no cursor). + +### Upstream change + +**`src/server/routes/session.ts`**: + +- Adds `before` query parameter with cursor validation +- When `limit` is provided with `before`, calls new `MessageV2.page()` instead of `Session.messages()` +- Returns pagination headers: `Link: ; rel="next"` and `X-Next-Cursor` +- When `limit=0` or no limit, returns all messages (backward compatible) +- All route param validators changed from `z.string()` to branded ID types + +**`src/session/message-v2.ts`**: + +- New `MessageV2.page()` function: cursor-based pagination using compound index `(session_id, time_created, id)` +- New `MessageV2.cursor` encode/decode utilities +- Branded ID types throughout (see item 2) + +**DB migration** (`20260312043431_session_message_cursor`): + +- Replaces `message_session_idx` with compound `message(session_id, time_created, id)` index +- Replaces `part_message_idx` with compound `part(message_id, id)` index + +### Files changed + +| File | Change | +| -------------------------------------------------- | ------------------------------------- | +| `src/server/routes/session.ts` | Pagination logic + branded ID params | +| `src/session/message-v2.ts` | `page()`, `cursor` codec, branded IDs | +| `migration/20260312043431_session_message_cursor/` | New compound indexes | + +### Rename needed + +None. + +### Desktop app impact + +**Medium.** Our frontend SSE adapter fetches messages via `GET /session/:id/messages`. The endpoint remains backward compatible (no `limit` = all messages), but we should update the SDK client types after regeneration. Future optimization: use pagination for large sessions. + +### Depends on + +- Branded ID types (item 2) -- routes use `SessionID.zod`, `MessageID.zod`, etc. +- DB migration (can be included in Phase 4's migration batch) + +--- + +## 8. Bun Shell ($) Removal + +### What it fixes + +Systematic removal of `import { $ } from "bun"` (bun shell) across ~10 files, replaced with `Process.run()`, `Process.text()`, native `fetch()`, `fs.chmod()`, and the new `git()` utility. Improves portability and error handling. + +### Current state in our fork + +Many files use `$` for shell commands. + +### Upstream change + +| File | `$` usage removed | Replaced with | +| ----------------------- | ------------------------------------ | ---------------------------------------- | +| `src/file/index.ts` | `$\`git diff\``, `$\`git ls-files\`` | `git()` utility | +| `src/file/watcher.ts` | `$\`git rev-parse\`` | `git()` utility | +| `src/file/ripgrep.ts` | `$\`${raw}\`` | `Process.text()` | +| `src/lsp/server.ts` | ~15 shell commands | `Process.run()`, `fetch()`, `fs.chmod()` | +| `src/snapshot/index.ts` | `$\`git --git-dir\`` | `Process.run()` with args helper | + +### New utility + +**`src/util/git.ts`** -- Already exists in our fork.

In particular, + * this means that we use "unsigned" where the 32bit headers say + * "unsigned long". + * - overall, we try to minimize the number of cases where we need to + * conditionally define different structures. + * - the "struct kernel_sigaction" class of structures have been + * modified to more closely mimic glibc's API by introducing an + * anonymous union for the function pointer. + * - a small number of field names had to have an underscore appended to + * them, because glibc defines a global macro by the same name. + */ + +/* include/linux/dirent.h */ +struct kernel_dirent64 { + unsigned long long d_ino; + long long d_off; + unsigned short d_reclen; + unsigned char d_type; + char d_name[256]; +}; + +/* include/linux/dirent.h */ +#if !defined(__NR_getdents) +// when getdents is not available, getdents64 is used for both. +#define kernel_dirent kernel_dirent64 +#else +struct kernel_dirent { + long d_ino; + long d_off; + unsigned short d_reclen; + char d_name[256]; +}; +#endif + +/* include/linux/uio.h */ +struct kernel_iovec { + void *iov_base; + unsigned long iov_len; +}; + +/* include/linux/socket.h */ +struct kernel_msghdr { + void *msg_name; + int msg_namelen; + struct kernel_iovec*msg_iov; + unsigned long msg_iovlen; + void *msg_control; + unsigned long msg_controllen; + unsigned msg_flags; +}; + +/* include/asm-generic/poll.h */ +struct kernel_pollfd { + int fd; + short events; + short revents; +}; + +/* include/linux/resource.h */ +struct kernel_rlimit { + unsigned long rlim_cur; + unsigned long rlim_max; +}; + +/* include/linux/time.h */ +struct kernel_timespec { + long tv_sec; + long tv_nsec; +}; + +/* include/linux/time.h */ +struct kernel_timeval { + long tv_sec; + long tv_usec; +}; + +/* include/linux/time.h */ +struct kernel_itimerval { + struct kernel_timeval it_interval; + struct kernel_timeval it_value; +}; + +/* include/linux/resource.h */ +struct kernel_rusage { + struct kernel_timeval ru_utime; + struct kernel_timeval ru_stime; + long ru_maxrss; + long ru_ixrss; + long ru_idrss; + long ru_isrss; + long ru_minflt; + long ru_majflt; + long ru_nswap; + long ru_inblock; + long ru_oublock; + long ru_msgsnd; + long ru_msgrcv; + long ru_nsignals; + long ru_nvcsw; + long ru_nivcsw; +}; + +#if defined(__i386__) || defined(__ARM_EABI__) || defined(__ARM_ARCH_3__) \ + || defined(__PPC__) || (defined(__s390__) && !defined(__s390x__)) \ + || defined(__e2k__) + +/* include/asm-{arm,i386,mips,ppc}/signal.h */ +struct kernel_old_sigaction { + union { + void (*sa_handler_)(int); + void (*sa_sigaction_)(int, siginfo_t *, void *); + }; + unsigned long sa_mask; + unsigned long sa_flags; + void (*sa_restorer)(void); +} __attribute__((packed,aligned(4))); +#elif (defined(__mips__) && _MIPS_SIM == _MIPS_SIM_ABI32) + #define kernel_old_sigaction kernel_sigaction +#elif defined(__aarch64__) || defined(__riscv) || defined(__loongarch_lp64) + // No kernel_old_sigaction defined for arm64 riscv and loongarch64. +#endif + +/* Some kernel functions (e.g. sigaction() in 2.6.23) require that the + * exactly match the size of the signal set, even though the API was + * intended to be extensible.

Note that this will +output the full default configuration with docs to stdout, so you may want to +pipe that through a pager, an editor, etc. + +Note: You'll see a lot of weird blank configurations like `font-family =`. This +is a valid syntax to specify the default behavior (no value). The `+show-config` +outputs it so it's clear that key is defaulting and also to have something to +attach the doc comment to. + +You can also see and read all available configuration options in the source +Config structure. The available keys are the keys verbatim, and their possible +values are typically documented in the comments. You also can search for +the public config files of many Ghostty users for examples and inspiration. + +## Configuration Errors + +If your configuration file has any errors, Ghostty does its best to ignore +them and move on. Configuration errors will be logged. + +## Debugging Configuration + +You can verify that configuration is being properly loaded by looking at the +debug output of Ghostty. + +In the debug output, you should see in the first 20 lines or so messages about +loading (or not loading) a configuration file, as well as any errors it may have +encountered. Configuration errors are also shown in a dedicated window on both +macOS and Linux (GTK). Ghostty does not treat configuration errors as fatal and +will fall back to default values for erroneous keys. + +You can also view the full configuration Ghostty is loading using `ghostty ++show-config` from the command-line. Use the `--help` flag to additional options +for that command. + +## Logging + +Ghostty can write logs to a number of destinations. On all platforms, logging to +`stderr` is available. Depending on the platform and how Ghostty was launched, +logs sent to `stderr` may be stored by the system and made available for later +retrieval. + +On Linux if Ghostty is launched by the default `systemd` user service, you can use +`journald` to see Ghostty's logs: `journalctl --user --unit app-com.mitchellh.ghostty.service`. + +On macOS logging to the macOS unified log is available and enabled by default. +--Use the system `log` CLI to view Ghostty's logs: `sudo log stream --level debug +--predicate 'subsystem=="com.mitchellh.ghostty"'`. + +Ghostty's logging can be configured in two ways. The first is by what +optimization level Ghostty is compiled with. If Ghostty is compiled with `Debug` +optimizations debug logs will be output to `stderr`. If Ghostty is compiled with +any other optimization the debug logs will not be output to `stderr`. + +Ghostty also checks the `GHOSTTY_LOG` environment variable. It can be used +to control which destinations receive logs. Ghostty currently defines two +destinations: + +- `stderr` - logging to `stderr`. +- `macos` - logging to macOS's unified log (has no effect on non-macOS platforms). + +Combine values with a comma to enable multiple destinations. Prefix a +destination with `no-` to disable it. Enabling and disabling destinations +can be done at the same time. Setting `GHOSTTY_LOG` to `true` will enable all +destinations. Setting `GHOSTTY_LOG` to `false` will disable all destinations. diff --git a/Terminal-app/src/build/mdgen/main_ghostty_1.zig b/Terminal-app/src/build/mdgen/main_ghostty_1.zig new file mode 100644 index 000000000..2bb413d93 --- /dev/null +++ b/Terminal-app/src/build/mdgen/main_ghostty_1.zig @@ -0,0 +1,16 @@ +const std = @import("std");

If a style is not set, then the regular style (font-family) +/// will be searched for stylistic variants. If a stylistic variant is not +/// found, Ghostty will use the regular style. This prevents falling back to a +/// different font family just to get a style such as bold. This also applies +/// if you explicitly specify a font family for a style. For example, if you +/// set `font-family-bold = FooBar` and "FooBar" cannot be found, Ghostty will +/// use whatever font is set for `font-family` for the bold style. +/// +/// Finally, some styles may be synthesized if they are not supported. +/// For example, if a font does not have an italic style and no alternative +/// italic font is specified, Ghostty will synthesize an italic style by +/// applying a slant to the regular style. If you want to disable these +/// synthesized styles then you can use the `font-style` configurations +/// as documented below. +/// +/// You can disable styles completely by using the `font-style` set of +/// configurations.

The format is `trigger=action`. Duplicate triggers will +/// overwrite previously set values. The list of actions is available in +/// the documentation or using the `ghostty +list-actions` command. +/// +/// Trigger: `+`-separated list of keys and modifiers. Example: `ctrl+a`, +/// `ctrl+shift+b`, `up`. +/// +/// If the key is a single Unicode codepoint, the trigger will match +/// any presses that produce that codepoint. These are impacted by +/// keyboard layouts. For example, `a` will match the `a` key on a +/// QWERTY keyboard, but will match the `q` key on a AZERTY keyboard +/// (assuming US physical layout). +/// +/// For Unicode codepoints, matching is done by comparing the set of +/// modifiers with the unmodified codepoint. The unmodified codepoint is +/// sometimes called an "unshifted character" in other software, but all +/// modifiers are considered, not only shift. For example, `ctrl+a` will match +/// `a` but not `ctrl+shift+a` (which is `A` on a US keyboard). +/// +/// Further, codepoint matching is case-insensitive and the unmodified +/// codepoint is always case folded for comparison. As a result, +/// `ctrl+A` configured will match when `ctrl+a` is pressed. Note that +/// this means some key combinations are impossible depending on keyboard +/// layout. For example, `ctrl+_` is impossible on a US keyboard because +/// `_` is `shift+-` and `ctrl+shift+-` is not equal to `ctrl+_` (because +/// the modifiers don't match!). More details on impossible key combinations +/// can be found at this excellent source written by Qt developers: +/// https://doc.qt.io/qt-6/qkeysequence.html#keyboard-layout-issues +/// +/// Physical key codes can be specified by using any of the key codes +/// as specified by the [W3C specification](https://www.w3.org/TR/uievents-code/). +/// For example, `KeyA` will match the physical `a` key on a US standard +/// keyboard regardless of the keyboard layout. These are case-sensitive. +/// +/// For aesthetic reasons, the w3c codes also support snake case. For +/// example, `key_a` is equivalent to `KeyA`. The only exceptions are +/// function keys, e.g. `F1` is `f1` (no underscore). This is a consequence +/// of our internal code using snake case but is purposely supported +/// and tested so it is safe to use. It allows an all-lowercase binding +/// which I find more aesthetically pleasing. +/// +/// Function keys such as `insert`, `up`, `f5`, etc. are also specified +/// using the keys as specified by the previously linked W3C specification. +/// +/// Physical keys always match with a higher priority than Unicode codepoints, +/// so if you specify both `a` and `KeyA`, the physical key will always be used +/// regardless of what order they are configured. +/// +/// The special key `catch_all` can be used to match any key that is not +/// otherwise bound. This can be combined with modifiers, for example +/// `ctrl+catch_all` will match any key pressed with `ctrl` that is not +/// otherwise bound. When looking up a binding, Ghostty first tries to match +/// `catch_all` with modifiers. If no match is found and the event has +/// modifiers, it falls back to `catch_all` without modifiers. +/// +/// Valid modifiers are `shift`, `ctrl` (alias: `control`), `alt` (alias: `opt`, +/// `option`), and `super` (alias: `cmd`, `command`). You may use the modifier +/// or the alias. When debugging keybinds, the non-aliased modifier will always +/// be used in output. +/// +/// Note: The fn or "globe" key on keyboards are not supported as a +/// modifier. This is a limitation of the operating systems and GUI toolkits +/// that Ghostty uses. +/// +/// Some additional notes for triggers: +/// +/// * modifiers cannot repeat, `ctrl+ctrl+a` is invalid. +/// +/// * modifiers and keys can be in any order, `shift+a+ctrl` is *weird*, +/// but valid. +/// +/// * only a single key input is allowed, `ctrl+a+b` is invalid. +/// +/// You may also specify multiple triggers separated by `>` to require a +/// sequence of triggers to activate the action. For example, +/// `ctrl+a>n=new_window` will only trigger the `new_window` action if the +/// user presses `ctrl+a` followed separately by `n`. In other software, this +/// is sometimes called a leader key, a key chord, a key table, etc. There +/// is no hardcoded limit on the number of parts in a sequence. +/// +/// Warning: If you define a sequence as a CLI argument to `ghostty`, +/// you probably have to quote the keybind since `>` is a special character +/// in most shells. Example: ghostty --keybind='ctrl+a>n=new_window' +/// +/// A trigger sequence has some special handling: +/// +/// * Ghostty will wait an indefinite amount of time for the next key in +/// the sequence. There is no way to specify a timeout. The only way to +/// force the output of a prefix key is to assign another keybind to +/// specifically output that key (e.g. `ctrl+a>ctrl+a=text:foo`) or +/// press an unbound key which will send both keys to the program. +/// +/// * If an unbound key is pressed during a sequence and a `catch_all` +/// binding exists that would `ignore` the input, the entire sequence +/// is dropped and nothing happens. Otherwise, the entire sequence is +/// encoded and sent to the running program as if no keybind existed. +/// +/// * If a prefix in a sequence is previously bound, the sequence will +/// override the previous binding. For example, if `ctrl+a` is bound to +/// `new_window` and `ctrl+a>n` is bound to `new_tab`, pressing `ctrl+a` +/// will do nothing. +/// +/// * Adding to the above, if a previously bound sequence prefix is +/// used in a new, non-sequence binding, the entire previously bound +/// sequence will be unbound. For example, if you bind `ctrl+a>n` and +/// `ctrl+a>t`, and then bind `ctrl+a` directly, both `ctrl+a>n` and +/// `ctrl+a>t` will become unbound. +/// +/// * Trigger sequences are not allowed for `global:` or `all:`-prefixed +/// triggers. This is a limitation we could remove in the future. +/// +/// Action is the action to take when the trigger is satisfied. It takes the +/// format `action` or `action:param`. The latter form is only valid if the +/// action requires a parameter. +/// +/// * `ignore` - Do nothing, ignore the key input. This can be used to +/// black hole certain inputs to have no effect. +/// +/// * `unbind` - Remove the binding. This makes it so the previous action +/// is removed, and the key will be sent through to the child command +/// if it is printable.

Double quotes or +/// other mechanisms are included and NOT parsed. If you want to +/// send a string value that includes spaces, wrap the entire +/// trigger/action in double quotes. Example: `--keybind="up=csi:A B"` +/// +/// There are some additional special values that can be specified for +/// keybind: +/// +/// * `keybind=clear` will clear all set keybindings. Warning: this +/// removes ALL keybindings up to this point, including the default +/// keybindings. +/// +/// The keybind trigger can be prefixed with some special values to change +/// the behavior of the keybind. These are: +/// +/// * `all:` +/// +/// Make the keybind apply to all terminal surfaces. By default, +/// keybinds only apply to the focused terminal surface. If this is true, +/// then the keybind will be sent to all terminal surfaces. This only +/// applies to actions that are surface-specific. For actions that +/// are already global (e.g. `quit`), this prefix has no effect. +/// +/// Available since: 1.0.0 +/// +/// * `global:` +/// +/// Make the keybind global. By default, keybinds only work within Ghostty +/// and under the right conditions (application focused, sometimes terminal +/// focused, etc.). If you want a keybind to work globally across your system +/// (e.g. even when Ghostty is not focused), specify this prefix. +/// This prefix implies `all:`. +/// +/// Note: this does not work in all environments; see the additional notes +/// below for more information. +/// +/// Available since: 1.0.0 on macOS, 1.2.0 on GTK +/// +/// * `unconsumed:` +/// +/// Do not consume the input. By default, a keybind will consume the input, +/// meaning that the associated encoding (if any) will not be sent to the +/// running program in the terminal. If you wish to send the encoded value +/// to the program, specify the `unconsumed:` prefix before the entire +/// keybind. For example: `unconsumed:ctrl+a=reload_config`. `global:` and +/// `all:`-prefixed keybinds will always consume the input regardless of +/// this setting. Since they are not associated with a specific terminal +/// surface, they're never encoded. +/// +/// Available since: 1.0.0 +/// +/// * `performable:` +/// +/// Only consume the input if the action is able to be performed. +/// For example, the `copy_to_clipboard` action will only consume the input +/// if there is a selection to copy. If there is no selection, Ghostty +/// behaves as if the keybind was not set. This has no effect with `global:` +/// or `all:`-prefixed keybinds. For key sequences, this will reset the +/// sequence if the action is not performable (acting identically to not +/// having a keybind set at all). +/// +/// Performable keybinds will not appear as menu shortcuts in the +/// application menu. This is because the menu shortcuts force the +/// action to be performed regardless of the state of the terminal. +/// Performable keybinds will still work, they just won't appear as +/// a shortcut label in the menu. +/// +/// Available since: 1.1.0 +/// +/// Keybind triggers are not unique per prefix combination. For example, +/// `ctrl+a` and `global:ctrl+a` are not two separate keybinds. The keybind +/// set later will overwrite the keybind set earlier. In this case, the +/// `global:` keybind will be used. +/// +/// Multiple prefixes can be specified. For example, +/// `global:unconsumed:ctrl+a=reload_config` will make the keybind global +/// and not consume the input to reload the config. +/// +/// Note: `global:` is only supported on macOS and certain Linux platforms. +/// +/// On macOS, this feature requires accessibility permissions to be granted +/// to Ghostty. When a `global:` keybind is specified and Ghostty is launched +/// or reloaded, Ghostty will attempt to request these permissions. +/// If the permissions are not granted, the keybind will not work. On macOS, +/// you can find these permissions in System Preferences -> Privacy & Security +/// -> Accessibility. +/// +/// On Linux, you need a desktop environment that implements the +/// [Global Shortcuts](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.GlobalShortcuts.html) +/// protocol as a part of its XDG desktop protocol implementation. +/// Desktop environments that are known to support (or not support) +/// global shortcuts include: +/// +/// - Users using KDE Plasma (since [5.27](https://kde.org/announcements/plasma/5/5.27.0/#wayland)) +/// and GNOME (since [48](https://release.gnome.org/48/#and-thats-not-all)) should be able +/// to use global shortcuts with little to no configuration. +/// +/// - Some manual configuration is required on Hyprland. Consult the steps +/// outlined on the [Hyprland Wiki](https://wiki.hyprland.org/Configuring/Binds/#dbus-global-shortcuts) +/// to set up global shortcuts correctly. +/// (Important: [`xdg-desktop-portal-hyprland`](https://wiki.hyprland.org/Hypr-Ecosystem/xdg-desktop-portal-hyprland/) +/// must also be installed!) +/// +/// - Notably, global shortcuts have not been implemented on wlroots-based +/// compositors like Sway (see [upstream issue](https://github.com/emersion/xdg-desktop-portal-wlr/issues/240)). +/// +/// ## Chained Actions +/// +/// A keybind can have multiple actions by using the `chain` keyword for +/// subsequent actions. When a keybind is activated, all chained actions are +/// executed in order. The syntax is: +/// +/// ```ini +/// keybind = ctrl+a=new_window +/// keybind = chain=goto_split:left +/// ``` +/// +/// This binds `ctrl+a` to first open a new window, then move focus to the +/// left split. Each `chain` entry appends an action to the most recently +/// defined keybind. You can chain as many actions as you want: +/// +/// ```ini +/// keybind = ctrl+a=new_window +/// keybind = chain=goto_split:left +/// keybind = chain=toggle_fullscreen +/// ``` +/// +/// Chained actions cannot have prefixes like `global:` or `unconsumed:`. +/// The flags from the original keybind apply to the entire chain. +/// +/// Chained actions work with key sequences as well. For example: +/// +/// ```ini +/// keybind = ctrl+a>n=new_window +/// keybind = chain=goto_split:left +/// ```` +/// +/// Chains with key sequences apply to the most recent binding in the +/// sequence. +/// +/// Chained keybinds are available since Ghostty 1.3.0. +/// +/// ## Key Tables +/// +/// You may also create a named set of keybindings known as a "key table." +/// A key table must be explicitly activated for the bindings to become +/// available. This can be used to implement features such as a +/// "copy mode", "vim mode", etc. Generically, this can implement modal +/// keyboard input. +/// +/// Key tables are defined using the syntax `/`. The +/// `` value is everything documented above for keybinds. The +/// `
` value is the name of the key table. Table names can contain +/// anything except `/`, `=`, `+`, and `>`. The characters `+` and `>` are +/// reserved for keybind syntax (modifier combinations and key sequences). +/// For example `foo/ctrl+a=new_window` defines a binding within a table +/// named `foo`. +/// +/// Tables are activated and deactivated using the binding actions +/// `activate_key_table:` and `deactivate_key_table`. Other table +/// related binding actions also exist; see the documentation for a full list. +/// These are the primary way to interact with key tables. +/// +/// Binding lookup proceeds from the innermost table outward, so keybinds in +/// the default table remain available unless explicitly unbound in an inner +/// table. +/// +/// A key table has some special syntax and handling: +/// +/// * `/` (with no binding) defines and clears a table, resetting all +/// of its keybinds and settings. +/// +/// * You cannot activate a table that is already the innermost table; such +/// attempts are ignored. However, the same table can appear multiple times +/// in the stack as long as it is not innermost (e.g., `A -> B -> A -> B` +/// is valid, but `A -> B -> B` is not). +/// +/// * A table can be activated in one-shot mode using +/// `activate_key_table_once:`. A one-shot table is automatically +/// deactivated when any non-catch-all binding is invoked. +/// +/// * Key sequences work within tables: `foo/ctrl+a>ctrl+b=new_window`. +/// If an invalid key is pressed, the sequence ends but the table remains +/// active. +/// +/// * Chain actions work within tables, the `chain` keyword applies to +/// the most recently defined binding in the table. e.g. if you set +/// `table/ctrl+a=new_window` you can chain by using `chain=text:hello`. +/// Important: chain itself doesn't get prefixed with the table name, +/// since it applies to the most recent binding in any table. +/// +/// * Prefixes like `global:` work within tables: +/// `foo/global:ctrl+a=new_window`. +/// +/// Key tables are available since Ghostty 1.3.0. +keybind: Keybinds = .{}, + +/// Remap modifier keys within Ghostty. This allows you to swap or reassign +/// modifier keys at the application level without affecting system-wide +/// settings. +/// +/// The format is `from=to` where both `from` and `to` are modifier key names. +/// You can use generic names like `ctrl`, `alt`, `shift`, `super` (macOS: +/// `cmd`/`command`) or sided names like `left_ctrl`, `right_alt`, etc. +/// +/// This will NOT change keyboard layout or key encodings outside of Ghostty. +/// For example, on macOS, `option+a` may still produce `å` even if `option` is +/// remapped to `ctrl`. Desktop environments usually handle key layout long +/// before Ghostty receives the key events. +/// +/// Example: +/// +/// key-remap = ctrl=super +/// key-remap = left_control=right_alt +/// +/// Important notes: +/// +/// * This is a one-way remap. If you remap `ctrl=super`, then the physical +/// Ctrl key acts as Super, but the Super key remains Super. +/// +/// * Remaps are not transitive. If you remap `ctrl=super` and `alt=ctrl`, +/// pressing Alt will produce Ctrl, NOT Super. +/// +/// * This affects both keybind matching and terminal input encoding. +/// This does NOT impact keyboard layout or how keys are interpreted +/// prior to Ghostty receiving them. For example, `option+a` on macOS +/// may still produce `å` even if `option` is remapped to `ctrl`. +/// +/// * Generic modifiers (e.g. `ctrl`) match both left and right physical keys. +/// Use sided names (e.g. `left_ctrl`) to remap only one side. +/// +/// There are other edge case scenarios that may not behave as expected +/// but are working as intended the way this feature is designed: +/// +/// * On macOS, bindings in the main menu will trigger before any remapping +/// is done. This is because macOS itself handles menu activation and +/// this happens before Ghostty receives the key event. To workaround +/// this, you should unbind the menu items and rebind them using your +/// desired modifier. +/// +/// This configuration can be repeated to specify multiple remaps. +@"key-remap": KeyRemapSet = .empty, + +/// Horizontal window padding.

For user documentation, see the main +README or [ghostty.org](https://ghostty.org/docs) + +## Implementation Details + +### Bash + +Automatic [Bash](https://www.gnu.org/software/bash/) shell integration works by +starting Bash in POSIX mode and using the `ENV` environment variable to load +our integration script (`bash/ghostty.bash`). This prevents Bash from loading +its normal startup files, which becomes our script's responsibility (along with +disabling POSIX mode). + +Bash shell integration can also be sourced manually from `bash/ghostty.bash`. +This also works for older versions of Bash. + +```bash +# Ghostty shell integration for Bash. This must be at the top of your bashrc! +if [ -n "${GHOSTTY_RESOURCES_DIR}" ]; then + builtin source "${GHOSTTY_RESOURCES_DIR}/shell-integration/bash/ghostty.bash" +fi +``` + +> [!NOTE] +> +> The version of Bash distributed with macOS (`/bin/bash`) does not support +> automatic shell integration. You'll need to manually source the shell +> integration script (as shown above). You can also install a standard +> version of Bash from Homebrew or elsewhere and set it as your shell. + +### Elvish + +For [Elvish](https://elv.sh), `$GHOSTTY_RESOURCES_DIR/src/shell-integration` +contains an `./elvish/lib/ghostty-integration.elv` file. + +Elvish, on startup, searches for paths defined in `XDG_DATA_DIRS` +variable for `./elvish/lib/*.elv` files and imports them. They are thus +made available for use as modules by way of `use `. + +Ghostty launches Elvish, passing the environment with `XDG_DATA_DIRS` prepended +with `$GHOSTTY_RESOURCES_DIR/src/shell-integration`. It contains +`./elvish/lib/ghostty-integration.elv`. The user can then import it +by `use ghostty-integration` every time after shell startup or +autostart integration in `$XDG_CONFIG_HOME/elvish/rc.elv`, +which will run the integration routines. + +If you decide to autostart `ghostty-integration` with `rc.elv`, you should +detect whether the terminal is Ghostty or not. To do this, add this to the end +of your `rc.elv` file: + +```elvish +if (eq $E:TERM "xterm-ghostty") { + try { use ghostty-integration } catch { } +} +``` + +The [Elvish](https://elv.sh) shell integration is supported by +the community and is not officially supported by Ghostty. We distribute +it for ease of access and use but do not provide support for it. +If you experience issues with the Elvish shell integration, I welcome +any contributions to fix them. Thank you! + +### Fish + +For [Fish](https://fishshell.com/), Ghostty prepends to the +`XDG_DATA_DIRS` directory. Fish automatically loads configuration +files in `/fish/vendor_conf.d/*.fish` on startup, +allowing us to automatically integrate with the shell. For details +on the Fish startup process, see the +[Fish documentation](https://fishshell.com/docs/current/language.html). + +### Nushell + +For [Nushell](https://www.nushell.sh/), Ghostty prepends to the +`XDG_DATA_DIRS` directory, making the `ghostty` module available through +Nushell's vendor autoload mechanism. Ghostty then automatically imports +the module using the `-e "use ghostty *"` flag when starting Nushell. + +Nushell provides many shell features itself, such as `title` and `cursor`, +so our integration focuses on Ghostty-specific features like `sudo`, +`ssh-env`, and `ssh-terminfo`. + +The shell integration is automatically enabled when running Nushell in Ghostty, +but you can also load it manually is shell integration is disabled: + +```nushell +source $GHOSTTY_RESOURCES_DIR/shell-integration/nushell/vendor/autoload/ghostty.nu +use ghostty * +``` + +### Zsh + +Automatic [Zsh](https://www.zsh.org/) integration works by temporarily setting +`ZDOTDIR` to our `zsh` directory. An existing `ZDOTDIR` environment variable +value will be retained and restored after our shell integration scripts are +run. + +However, if `ZDOTDIR` is set in a system-wide file like `/etc/zshenv`, it will +override Ghostty's `ZDOTDIR` value, preventing the shell integration from being +loaded. In this case, the shell integration needs to be loaded manually. + +To load the Zsh shell integration manually: + +```zsh +if [[ -n $GHOSTTY_RESOURCES_DIR ]]; then + source "$GHOSTTY_RESOURCES_DIR"/shell-integration/zsh/ghostty-integration +fi +``` + +Shell integration requires Zsh 5.1+. diff --git a/Terminal-app/src/shell-integration/bash/bash-preexec.sh b/Terminal-app/src/shell-integration/bash/bash-preexec.sh new file mode 100644 index 000000000..f20ece179 --- /dev/null +++ b/Terminal-app/src/shell-integration/bash/bash-preexec.sh @@ -0,0 +1,382 @@ +# bash-preexec.sh -- Bash support for ZSH-like 'preexec' and 'precmd' functions. +# https://github.com/rcaloras/bash-preexec +# +# +# 'preexec' functions are executed before each interactive command is +# executed, with the interactive command as its argument.

The pixel data consists of *y scanlines of *x pixels, +// with each pixel consisting of N interleaved 8-bit components; the first +// pixel pointed to is top-left-most in the image. There is no padding between +// image scanlines or between pixels, regardless of format.

If desired_channels is non-zero, +// *channels_in_file has the number of components that _would_ have been +// output otherwise. E.g. if you set desired_channels to 4, you will always +// get RGBA output, but you can check *channels_in_file to see if it's trivially +// opaque because e.g. there were only 3 channels in the source image. +// +// An output image with N components has the following components interleaved +// in this order in each pixel: +// +// N=#comp components +// 1 grey +// 2 grey, alpha +// 3 red, green, blue +// 4 red, green, blue, alpha +// +// If image loading fails for any reason, the return value will be NULL, +// and *x, *y, *channels_in_file will be unchanged. The function +// stbi_failure_reason() can be queried for an extremely brief, end-user +// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS +// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly +// more user-friendly ones. +// +// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized. +// +// To query the width, height and component count of an image without having to +// decode the full file, you can use the stbi_info family of functions: +// +// int x,y,n,ok; +// ok = stbi_info(filename, &x, &y, &n); +// // returns ok=1 and sets x, y, n if image is a supported format, +// // 0 otherwise. +// +// Note that stb_image pervasively uses ints in its public API for sizes, +// including sizes of memory buffers. This is now part of the API and thus +// hard to change without causing breakage. As a result, the various image +// loaders all have certain limits on image size; these differ somewhat +// by format but generally boil down to either just under 2GB or just under +// 1GB. When the decoded image would be larger than this, stb_image decoding +// will fail. +// +// Additionally, stb_image will reject image files that have any of their +// dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, +// which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, +// the only way to have an image with such dimensions load correctly +// is for it to have a rather extreme aspect ratio. Either way, the +// assumption here is that such larger images are likely to be malformed +// or malicious. If you do need to load an image with individual dimensions +// larger than that, and it still fits in the overall size limit, you can +// #define STBI_MAX_DIMENSIONS on your own to be something larger. +// +// =========================================================================== +// +// UNICODE: +// +// If compiling for Windows and you wish to use Unicode filenames, compile +// with +// #define STBI_WINDOWS_UTF8 +// and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert +// Windows wchar_t filenames to utf8. +// +// =========================================================================== +// +// Philosophy +// +// stb libraries are designed with the following priorities: +// +// 1. easy to use +// 2. easy to maintain +// 3. good performance +// +// Sometimes I let "good performance" creep up in priority over "easy to maintain", +// and for best performance I may provide less-easy-to-use APIs that give higher +// performance, in addition to the easy-to-use ones. Nevertheless, it's important +// to keep in mind that from the standpoint of you, a client of this library, +// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. +// +// Some secondary priorities arise directly from the first two, some of which +// provide more explicit reasons why performance can't be emphasized. +// +// - Portable ("ease of use") +// - Small source code footprint ("easy to maintain") +// - No dependencies ("ease of use") +// +// =========================================================================== +// +// I/O callbacks +// +// I/O callbacks allow you to read from arbitrary sources, like packaged +// files or some other source. Data read from callbacks are processed +// through a small internal buffer (currently 128 bytes) to try to reduce +// overhead. +// +// The three functions you must define are "read" (reads some bytes of data), +// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). +// +// =========================================================================== +// +// SIMD support +// +// The JPEG decoder will try to automatically use SIMD kernels on x86 when +// supported by the compiler. For ARM Neon support, you must explicitly +// request it. +// +// (The old do-it-yourself SIMD API is no longer supported in the current +// code.) +// +// On x86, SSE2 will automatically be used when available based on a run-time +// test; if not, the generic C versions are used as a fall-back. On ARM targets, +// the typical path is to have separate builds for NEON and non-NEON devices +// (at least this is true for iOS and Android). Therefore, the NEON support is +// toggled by a build flag: define STBI_NEON to get NEON loops. +// +// If for some reason you do not want to use any of SIMD code, or if +// you have issues compiling it, you can disable it entirely by +// defining STBI_NO_SIMD. +// +// =========================================================================== +// +// HDR image support (disable by defining STBI_NO_HDR) +// +// stb_image supports loading HDR images in general, and currently the Radiance +// .HDR file format specifically. You can still load any file through the existing +// interface; if you attempt to load an HDR file, it will be automatically remapped +// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; +// both of these constants can be reconfigured through this interface: +// +// stbi_hdr_to_ldr_gamma(2.2f); +// stbi_hdr_to_ldr_scale(1.0f); +// +// (note, do not use _inverse_ constants; stbi_image will invert them +// appropriately). +// +// Additionally, there is a new, parallel interface for loading files as +// (linear) floats to preserve the full dynamic range: +// +// float *data = stbi_loadf(filename, &x, &y, &n, 0); +// +// If you load LDR images through this interface, those images will +// be promoted to floating point values, run through the inverse of +// constants corresponding to the above: +// +// stbi_ldr_to_hdr_scale(1.0f); +// stbi_ldr_to_hdr_gamma(2.2f); +// +// Finally, given a filename (or an open file or memory block--see header +// file for details) containing image data, you can query for the "most +// appropriate" interface to use (that is, whether the image is HDR or +// not), using: +// +// stbi_is_hdr(char *filename); +// +// =========================================================================== +// +// iPhone PNG support: +// +// We optionally support converting iPhone-formatted PNGs (which store +// premultiplied BGRA) back to RGB, even though they're internally encoded +// differently. To enable this conversion, call +// stbi_convert_iphone_png_to_rgb(1). +// +// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per +// pixel to remove any premultiplied alpha *only* if the image file explicitly +// says there's premultiplied data (currently only happens in iPhone images, +// and only if iPhone convert-to-rgb processing is on). +// +// =========================================================================== +// +// ADDITIONAL CONFIGURATION +// +// - You can suppress implementation of any of the decoders to reduce +// your code footprint by #defining one or more of the following +// symbols before creating the implementation. +// +// STBI_NO_JPEG +// STBI_NO_PNG +// STBI_NO_BMP +// STBI_NO_PSD +// STBI_NO_TGA +// STBI_NO_GIF +// STBI_NO_HDR +// STBI_NO_PIC +// STBI_NO_PNM (.ppm and .pgm) +// +// - You can request *only* certain decoders and suppress all other ones +// (this will be more forward-compatible, as addition of new decoders +// doesn't require you to disable them explicitly): +// +// STBI_ONLY_JPEG +// STBI_ONLY_PNG +// STBI_ONLY_BMP +// STBI_ONLY_PSD +// STBI_ONLY_TGA +// STBI_ONLY_GIF +// STBI_ONLY_HDR +// STBI_ONLY_PIC +// STBI_ONLY_PNM (.ppm and .pgm) +// +// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still +// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB +// +// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater +// than that size (in either width or height) without further processing. +// This is to let programs in the wild set an upper bound to prevent +// denial-of-service attacks on untrusted data, as one could generate a +// valid image of gigantic dimensions and force stb_image to allocate a +// huge block of memory and spend disproportionate time decoding it.

For a list of + supported filters see the stbir_filter enum. To add a new filter, + write a filter function and add it to stbir__filter_info_table. + + PROGRESS + For interactive use with slow resize operations, you can install + a progress-report callback: + + #define STBIR_PROGRESS_REPORT(val) some_func(val) + + The parameter val is a float which goes from 0 to 1 as progress is made. + + For example: + + static void my_progress_report(float progress); + #define STBIR_PROGRESS_REPORT(val) my_progress_report(val) + + #define STB_IMAGE_RESIZE_IMPLEMENTATION + #include "stb_image_resize.h" + + static void my_progress_report(float progress) + { + printf("Progress: %f%%\n", progress*100); + } + + MAX CHANNELS + If your image has more than 64 channels, define STBIR_MAX_CHANNELS + to the max you'll have. + + ALPHA CHANNEL + Most of the resizing functions provide the ability to control how + the alpha channel of an image is processed. The important things + to know about this: + + 1. The best mathematically-behaved version of alpha to use is + called "premultiplied alpha", in which the other color channels + have had the alpha value multiplied in. If you use premultiplied + alpha, linear filtering (such as image resampling done by this + library, or performed in texture units on GPUs) does the "right + thing". While premultiplied alpha is standard in the movie CGI + industry, it is still uncommon in the videogame/real-time world. + + If you linearly filter non-premultiplied alpha, strange effects + occur. (For example, the 50/50 average of 99% transparent bright green + and 1% transparent black produces 50% transparent dark green when + non-premultiplied, whereas premultiplied it produces 50% + transparent near-black. The former introduces green energy + that doesn't exist in the source image.) + + 2. Artists should not edit premultiplied-alpha images; artists + want non-premultiplied alpha images. Thus, art tools generally output + non-premultiplied alpha images. + + 3. You will get best results in most cases by converting images + to premultiplied alpha before processing them mathematically. + + 4. If you pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, the + resizer does not do anything special for the alpha channel; + it is resampled identically to other channels. This produces + the correct results for premultiplied-alpha images, but produces + less-than-ideal results for non-premultiplied-alpha images. + + 5. If you do not pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, + then the resizer weights the contribution of input pixels + based on their alpha values, or, equivalently, it multiplies + the alpha value into the color channels, resamples, then divides + by the resultant alpha value. Input pixels which have alpha=0 do + not contribute at all to output pixels unless _all_ of the input + pixels affecting that output pixel have alpha=0, in which case + the result for that pixel is the same as it would be without + STBIR_FLAG_ALPHA_PREMULTIPLIED. However, this is only true for + input images in integer formats. For input images in float format, + input pixels with alpha=0 have no effect, and output pixels + which have alpha=0 will be 0 in all channels. (For float images, + you can manually achieve the same result by adding a tiny epsilon + value to the alpha channel of every image, and then subtracting + or clamping it at the end.) + + 6. You can suppress the behavior described in #5 and make + all-0-alpha pixels have 0 in all channels by #defining + STBIR_NO_ALPHA_EPSILON. + + 7. You can separately control whether the alpha channel is + interpreted as linear or affected by the colorspace. By default + it is linear; you almost never want to apply the colorspace. + (For example, graphics hardware does not apply sRGB conversion + to the alpha channel.) + + CONTRIBUTORS + Jorge L Rodriguez: Implementation + Sean Barrett: API design, optimizations + Aras Pranckevicius: bugfix + Nathan Reed: warning fixes + + REVISIONS + 0.97 (2020-02-02) fixed warning + 0.96 (2019-03-04) fixed warnings + 0.95 (2017-07-23) fixed warnings + 0.94 (2017-03-18) fixed warnings + 0.93 (2017-03-03) fixed bug with certain combinations of heights + 0.92 (2017-01-02) fix integer overflow on large (>2GB) images + 0.91 (2016-04-02) fix warnings; fix handling of subpixel regions + 0.90 (2014-09-17) first released version + + LICENSE + See end of file for license information. + + TODO + Don't decode all of the image data when only processing a partial tile + Don't use full-width decode buffers when only processing a partial tile + When processing wide images, break processing into tiles so data fits in L1 cache + Installable filters? + Resize that respects alpha test coverage + (Reference code: FloatImage::alphaTestCoverage and FloatImage::scaleAlphaToCoverage: + https://code.google.com/p/nvidia-texture-tools/source/browse/trunk/src/nvimage/FloatImage.cpp ) +*/ + +#ifndef STBIR_INCLUDE_STB_IMAGE_RESIZE_H +#define STBIR_INCLUDE_STB_IMAGE_RESIZE_H + +#ifdef _MSC_VER +typedef unsigned char stbir_uint8; +typedef unsigned short stbir_uint16; +typedef unsigned int stbir_uint32; +#else +#include +typedef uint8_t stbir_uint8; +typedef uint16_t stbir_uint16; +typedef uint32_t stbir_uint32; +#endif + +#ifndef STBIRDEF +#ifdef STB_IMAGE_RESIZE_STATIC +#define STBIRDEF static +#else +#ifdef __cplusplus +#define STBIRDEF extern "C" +#else +#define STBIRDEF extern +#endif +#endif +#endif + +////////////////////////////////////////////////////////////////////////////// +// +// Easy-to-use API: +// +// * "input pixels" points to an array of image data with 'num_channels' channels (e.g. RGB=3, RGBA=4) +// * input_w is input image width (x-axis), input_h is input image height (y-axis) +// * stride is the offset between successive rows of image data in memory, in bytes. you can +// specify 0 to mean packed continuously in memory +// * alpha channel is treated identically to other channels. +// * colorspace is linear or sRGB as specified by function name +// * returned result is 1 for success or 0 in case of an error. +// #define STBIR_ASSERT() to trigger an assert on parameter validation errors. +// * Memory required grows approximately linearly with input and output size, but with +// discontinuities at input_w == output_w and input_h == output_h. +// * These functions use a "default" resampling filter defined at compile time.

This file contains a fork of the Zig stdlib HashMap implementation tuned +//! for use with our terminal page representation. +//! +//! The main goal we need to achieve that wasn't possible with the stdlib +//! HashMap is to utilize offsets rather than full pointers so that we can +//! copy around the entire backing memory and keep the hash map working. +//! +//! Additionally, for serialization/deserialization purposes, we need to be +//! able to create a HashMap instance and manually set the offsets up. The +//! stdlib HashMap does not export Metadata so this isn't possible. +//! +//! Also, I want to be able to understand possible capacity for a given K,V +//! type and fixed memory amount. The stdlib HashMap doesn't publish its +//! internal allocation size calculation. +//! +//! Finally, I removed many of the APIs that we'll never require for our +//! usage just so that this file is smaller, easier to understand, and has +//! less opportunity for bugs. +//! +//! Besides these shortcomings, the stdlib HashMap has some great qualities +//! that we want to keep, namely the fact that it is backed by a single large +//! allocation rather than pointers to separate allocations. This is important +//! because our terminal page representation is backed by a single large +//! allocation so we can give the HashMap a slice of memory to operate in. +//! +//! I haven't carefully benchmarked this implementation against other hash +//! map implementations. It's possible using some of the newer variants out +//! there would be better. However, I trust the built-in version is pretty good +//! and its more important to get the terminal page representation working +//! first then we can measure and improve this later if we find it to be a +//! bottleneck. + +const std = @import("std"); +const assert = @import("../quirks.zig").inlineAssert; +const autoHash = std.hash.autoHash; +const math = std.math; +const mem = std.mem; +const Allocator = mem.Allocator; +const Wyhash = std.hash.Wyhash; + +const Offset = @import("size.zig").Offset; +const OffsetBuf = @import("size.zig").OffsetBuf; +const getOffset = @import("size.zig").getOffset; + +pub fn AutoOffsetHashMap(comptime K: type, comptime V: type) type { + return OffsetHashMap(K, V, AutoContext(K)); +} + +fn AutoHashMapUnmanaged(comptime K: type, comptime V: type) type { + return HashMapUnmanaged(K, V, AutoContext(K)); +} + +fn AutoContext(comptime K: type) type { + return struct { + pub const hash = std.hash_map.getAutoHashFn(K, @This()); + pub const eql = std.hash_map.getAutoEqlFn(K, @This()); + }; +} + +/// A HashMap type that uses offsets rather than pointers, making it +/// possible to efficiently move around the backing memory without +/// invalidating the HashMap. +pub fn OffsetHashMap( + comptime K: type, + comptime V: type, + comptime Context: type, +) type { + return struct { + const Self = @This(); + + /// This is the pointer-based map that we're wrapping. + pub const Unmanaged = HashMapUnmanaged(K, V, Context); + pub const Layout = Unmanaged.Layout; + + /// This is the alignment that the base pointer must have. + pub const base_align = Unmanaged.base_align; + + metadata: Offset(Unmanaged.Metadata) = .{}, + + /// Returns the total size of the backing memory required for a + /// HashMap with the given capacity.

A library for injecting failures into Zig code for the express +//! purpose of testing error handling paths. +//! +//! Improper `errdefer` is one of the highest sources of bugs in Zig code. +//! Many `errdefer` points are hard to exercise in unit tests and rare +//! to encounter in production, so they often hide bugs. Worse, error +//! scenarios are most likely to put your code in an unexpected state +//! that can result in future assertion failures or memory safety issues. +//! +//! This module aims to solve this problem by providing a way to inject +//! errors at specific points in your code during unit tests, allowing you +//! to test every possible error path. +//! +//! # Usage +//! +//! To use this package, create a `tripwire.module` for each failable +//! function you want to test. The enum must be hand-curated to be the +//! set of fail points, and the error set comes directly from the function +//! itself. +//! +//! Pepper your function with `try tw.check` calls wherever you want to +//! have a testable failure point. You don't need every "try" to have +//! an associated tripwire check, only the ones you care about testing. +//! Usually, this is going to be the points where you want to test +//! errdefer logic above it. +//! +//! In unit tests, add `try tw.errorAlways` or related calls to +//! configure expected failures. Then, call your function. Finally, always +//! call `try tw.end(.reset)` to verify your expectations were met and +//! to reset the tripwire module for future tests. +//! +//! ``` +//! const tw = tripwire.module(enum { alloc_buf, open_file }, myFunction); +//! +//! fn myFunction() tw.Error!void { +//! try tw.check(.alloc_buf); +//! const buf = try allocator.alloc(u8, 1024); +//! errdefer allocator.free(buf); +//! +//! try tw.check(.open_file); +//! const file = try std.fs.cwd().openFile("foo.txt", .{}); +//! // ... +//! } +//! +//! test "myFunction fails on alloc" { +//! tw.errorAlways(.alloc_buf, error.OutOfMemory); +//! try std.testing.expectError(error.OutOfMemory, myFunction()); +//! try tw.end(.reset); +//! } +//! ``` +//! +//! ## Transitive Function Calls +//! +//! To test transitive calls, there are two schools of thought: +//! +//! 1. Put a failure point above the transitive call in the caller +//! and assume the child function error handling works correctly. +//! +//! 2. Create another tripwire module for the child function and +//! trigger failures there. This is recommended if the child function +//! can't really be called in isolation (e.g. its an auxiliary function +//! to a public API). +//! +//!
