-Plugins add actions, completion, quick fixes, tool windows, custom editors,
-themes, file icons and languages. They run as sandboxed WebAssembly components;
-themes, icon themes and languages need no code at all.

l0ng-ai	20281e9b66	fix(plugins): Windows: local marketplace paths, localhost connections, tests - A marketplace index given as a local Windows path (`C:\market\index.json`) resolves its packages next to it; only URLs are joined with `/`. - HTTP requests to `localhost` try IPv4 loopback first, then IPv6: local servers such as Ollama usually listen on IPv4, and on Windows a refused `::1` cost about two seconds per request. - Tests that assumed Unix: an absolute program path is the platform's, a manifest rewritten by a test may have CRLF line ends, the precompiled-cache test replaces the cache file only after the host that maps it is gone, and the MyBatis test lets its first call build the index before asserting. - The icon theme test's time limits guard against work growing faster than the icon count rather than measure the runner.	2026-11-04 02:41:46 +08:00
l0ng-ai	20960c1d96	fix(plugins): soft deadlines hold under load, unique cache writes, CI on every platform - A provider result produced after its soft deadline is dropped even when it is already waiting (the caller was scheduled late or waited on another plugin first), so the deadline holds on a busy machine. The result is timestamped when the plugin's thread produces it, so a result that came in time is still used when it is read late. - Each precompiled-component write uses its own temporary file: two threads storing the same component could rename a half-written file into place. - Tests: the cache-corruption case replaces the file instead of overwriting the one a running component maps; the yield test no longer counts on a tick rate; a test that runs a shell script is Unix-only like its neighbours. - Plugin web pages declare `@types/node` for their Vite configs instead of finding the repository's.	2026-11-04 02:41:46 +08:00
l0ng-ai	9cc83c77b8	feat(plugins): plugin contributions in the IDE's own settings and menus; official plugins published with releases - Themes: a plugin theme is an `appearance.theme` value (`plugin:<id>/<theme>`), offered by Settings › Appearance (and the preferred themes of Sync with OS), Quick Switch, the toolbar gear menu and Welcome › Customize. The project window selects it in the plugin host; picking a built-in theme clears it. While its plugin is off, the built-in theme of its kind shows and the choice is kept. - File icon themes: chosen in Settings › Appearance › File icon theme and kept in `appearance.fileIconTheme`, so every window follows. - Keymap: plugins' default shortcuts show in Settings › Keymap as the defaults of their actions: removable, changeable, resettable and part of conflict checks. - Problems: a plugin's problems are withdrawn when it stops, fails, is disabled or uninstalled. Settings › Inspections lists them under Plugins by plugin name; stored overrides of `plugin:` producers parse correctly. - Status bar items of plugins are named in the status bar menu and can be hidden. - Languages added or removed by plugins refresh Override File Type, the Code Style pages and Inspections without a restart. - Uninstalling a plugin deletes the secrets it declared. - The Settings window follows plugin changes made elsewhere. - The plugin system is marked Preview (Settings › Plugins, README); Harbor Night is versioned 0.1.0 like the other official plugins. - Release: the official plugins are packed, signed (secret PLUGIN_SIGNING_KEY) and indexed into the release as `plugins-index.json`; released builds use it as the default marketplace. Without the key the step is skipped.	2026-11-04 02:41:46 +08:00
l0ng-ai	ac71b7008e	feat(plugins): Graphviz, Regex Tester, License Header and Harbor Night official plugins - Graphviz: `.dot` / `.gv` files open beside a live preview (a web view rendering with Graphviz compiled to WebAssembly) in any layout engine, with zoom, pan, Fit and SVG / PNG export through the save dialog. What Graphviz reports goes from the page to the plugin's code, which publishes it as problems on the named line. A DOT language, file icons and a New Graphviz Graph template. - Regex Tester: a tool window whose html view sends pattern, flags, text and replacement as you type; the plugin matches with Rust's regex (linear time) and answers with matches, groups and the replacement in UTF-16 offsets. Use Selection and Test Selection take the editor's selection. - License Header: files without a copyright / SPDX header are reported when they open and on save; a quick fix and a command add one in the file's comment syntax (after a shebang or encoding line); a project scan in a background task reports the rest. Holder and license are settings. - Harbor Night becomes an official plugin and the one source of the theme files: `openidea-plugin new --template theme`, the theme docs and tests start from it. - Tool windows' renders and events carry the window's active editor, as commands do, so a view's buttons can act on what the user is editing. - knip leaves plugins' web pages (projects of their own) alone.	2026-11-04 02:41:46 +08:00
l0ng-ai	3b78d15d6d	refactor(plugins): drop the Kubernetes plugin, samples become test fixtures - Remove the Kubernetes official plugin. - `hello` and `language-toy` move from `plugins/` to `crates/ide-plugin/tests/fixtures/`: they stay what the host's tests run against, but are no longer listed as plugins of the repository. - A `jobs` fixture takes over what only Kubernetes exercised: a tree view filled by a pinned program, a terminal for the activated entry in the invoking window, string and number settings, locally and in remote projects. - `plugins/` now holds only the official plugins; `build.sh`, CI and the debug plugin catalog follow.	2026-11-04 02:41:46 +08:00
l0ng-ai	3f52439703	chore(plugins): regenerate bindings and reconcile with main - Regenerated bindings for the merged settings, edits and plugin commands. - Mouse shortcuts run their action through `executeAction` again. - Dropped Chinese entries whose templates main already translates.	2026-11-04 02:41:46 +08:00
l0ng-aiandflorentvdry	a7b7616da9	feat(plugins): install packages from a .zip or a folder's plugin.toml Install Plugin from Package File now takes an `.oiplugin`, a `.zip` or a package folder's `plugin.toml`, and goes through the same install page (capabilities, signature, consent) as every other install. - A zip may hold the package at its root or in its only folder, as zipping the folder makes; archiver metadata (`__MACOSX`, `.DS_Store`, `._*`) is left out. A zip without a `plugin.toml` there, such as an IntelliJ plugin, is refused with a message saying so. Unsafe paths, links and size limits are checked as for `.oiplugin` files. - Picking a `plugin.toml` installs its folder. Co-authored-by: florentvdry <[email protected]>	2026-11-04 02:41:46 +08:00
l0ng-aiandDeng Liu	900f2e6819	feat(plugins): web views, document bridge and the Excalidraw official plugin Plugins can now ship a web page as the UI of a view or custom editor (`web = "web/index.html"`), so editors built on web libraries are plugins rather than part of the core. - Web views: every file under the page's directory is part of the package (checked, copied on install, covered by the digest and signature) and served through the `openidea-plugin` URL scheme, under a per-revision path with a CSP of its own, into an `<iframe sandbox="allow-scripts">`. An update or reinstall reloads open pages. - Frame bridge (`window.openidea`), shared by html bodies and web pages: theme, messages to the plugin's code, `document.get/edit/replace/onChange` (versioned edits that join the text editor's undo history, Save and dirty state), `saveFile`/`openFile` through the IDE's dialogs, and IDE shortcuts the page leaves alone. - Custom editor layouts: tab, split (Editor and X) or preview over the text editor, switchable from the tab's actions. - New points `fileIcons` and `fileTemplates`; new optional capability `clipboard` for web views. - Excalidraw official plugin: `.excalidraw` / `.excalidraw.json` open as an interactive canvas kept in step with the file's text, with self-hosted fonts, PNG/SVG export, images, file icons, a New Drawing template and JSON highlighting. Closes #732. - Fixes: a lock-order deadlock between listing plugins and refreshing project pins; the dev server ignored edits under `src/features/plugins`. - `plugins/build.sh` builds and checks web pages; CI typechecks and tests them.

l0ng-ai	78e0c7a23e	feat(plugins): finalize plugin API before release, concurrent providers Plugin API (breaking; the plugin system is unreleased): - Remove the runtime `contributions` interface (register-command, register-language, register-theme). Commands, languages and themes are declared in plugin.toml only, so everything a plugin contributes goes through the install preview and consent. The registry drops runtime scope, `contribute` and `dispose_runtime`; inline `definition` in language and theme declarations is gone. - `completion-item.kind` is a string (the 25 LSP kinds; unknown kinds show no icon), like the other open-ended kinds. - `lifecycle.activate` and `commands.run` return `types.error` instead of a string. The host maps it to the matching error kind, and only `failed` counts against the plugin: cancelling, a missing grant or an unknown command does not. The SDK's `Plugin` returns `Result<_, Error>`; plain messages convert to `Error::Failed`. Runtime: - Editor providers of several plugins are called at the same time (`Actor::submit` + `Pending::wait`): the wait is the slowest plugin's, not the sum, so each gets the full edit-path budget. Versioning and tooling: - Components are checked at install and by `openidea-plugin check` for the plugin API they were built for; another major or a newer minor is refused with what to do. - Tests: the SDK's WIT matches the host's, a simulated next-minor host links every shipped component, every host function has an SDK wrapper, released APIs only grow (no snapshot until the first release). - plugins/build.sh builds every checked-in component, records a source fingerprint next to it, and `--check` fails on stale components; CI runs it plus fmt, clippy (host and wasm) and tests for the SDK, the official plugins and the fixtures. - The API evolution rules and the checklist for a new host function are in plugins/README.md; the design notes under docs/ are removed.	2026-11-04 02:41:46 +08:00
l0ng-ai	fa003016ef	feat(plugins): theme variables for html view frames, kept current without reload - Inject `data-theme` and stable `--openidea-*` colour and font variables (concrete values; the frame has no IDE stylesheet) into html view bodies. - Post theme changes to the loaded frame instead of rebuilding srcdoc, so a theme switch keeps the frame's state; re-send on load to close the race. - Expose `openidea.theme` / `openidea.onThemeChange` to frame scripts. - Move `subscribeTheme` / `themeKey` from the Markdown mermaid module to `src/platform/themeWatch.ts`, shared by both. - Document the variables in plugins/README.md.	2026-11-04 02:41:46 +08:00
l0ng-ai	fd1f465aeb	feat(plugins): extension points, capability consent, async runtime and plugin API 1.0 Rework the plugin system per docs/plugin_plan.md (P0–P8): - Extension-point registry (ide-extension) so new contribution types register without touching the kernel; languages, run detectors, providers, views and UI contributions go through it. - Per-plugin capability consent with a risk-graded ledger; process capabilities are pinned to resolved binary paths and hashes. - Async, actor-per-plugin Wasm runtime with lazy activation, cancellation, events, long-running tasks and idle reclamation. - Plugin host moved into ide-host, shared by local and remote projects. - Distribution: install/package tooling (openidea-plugin bin) and a static market index. - WIT frozen as openidea:[email protected]; Rust SDK with mock host. - Ten official validation plugins under plugins/official.	2026-11-04 02:41:46 +08:00
