Increase, Decrease and Reset Font Size only reached the active CodeMirror editor, so they did nothing with focus in a terminal or plugin WebView. They now apply to the focused surface through a shared workbench service: an editor tab, a terminal tab (which refits), or a plugin WebView. Wheel zoom stays pointer-based.

views.open-log-tab(key, title, process-log) (SDK host::open_log_tab) opens the read-only log tab a web view opens with open-log-tab, from a command or event of a window, reusing the Services pane's process-log.
The host checks the process grant and limits when called and remembers what each key runs in that window; the tab starts it by key (plugin_log_tab_spawn) through the web-view PTY checks: pinned program, trusted project, session cap, lifecycle and grant revocation. Remote windows report that these tabs aren't available there yet.
- workspace.symbols becomes the project method project.symbols(query, limit), like find-files; the Rust SDK's Project::symbols is unchanged, components built against the previous main need a rebuild.
- The open-log-tab web message names its arguments args, as pty-spawn and the services process-log do; baseArgs is refused with log-error rather than ignored.
- Document the hover, semantic-tokens and diagnostics provider exports and their worlds.
Closes#1720
Plugins can declare searchable multi-page settings (API 1.3): pages under the plugin in Settings, groups, string lists, editable tables and command buttons, while single-schema plugins keep working. A command button applies pending edits first and runs against the selected Global/Project layer (also remotely); Reset keeps other pages' edits, and invalid table/list edits never replace saved rows. Field and page order come from the schema without changing serde_json's map ordering elsewhere in the app.

Uninstall keeps a plugin registered but stopped until its private data, secrets and package are cleaned up; a failure is shown and Uninstall can be retried, also after a restart (a durable cleanup record outside the package restores the target). While cleanup is pending, enable, reload, consent, permission changes, reinstall, replacement and rollback are refused. Secret-deletion errors are reported, and cleanup never follows a symlinked ancestor outside plugin storage. The SDK mock checks private-path components and rejects traversal independently of filesystem grants.

A plugin web view can open an editor tab with its own title, language (or file name for detection), content and toolbar actions (API 1.3). Clicking an action sends `{ action, content }` back to the plugin, which replies with new content and/or a status message, or left/right content shown in the IDE's diff viewer. The tab follows the editor document lifecycle: modified marker, close-with-changes prompt, read-only, and saves whose reply arrives after newer edits (or that the plugin rejects) keep the document dirty.

A tool-window web view can declare `header = "none"` (API 1.3) to render its own header. The host then replaces the standard header with corner actions (Options, Hide) once the frame has loaded, and tells the frame the corner inset to keep free (CSS variables) so the actions don't cover the plugin's controls. Views without the declaration, and the loading and error states of every view, keep the standard header.

API 1.3 adds a diagnostics provider for unsaved documents: the host sends versioned text for the declared languages after a 300 ms debounce, cancels superseded calls, drops late or stale answers under the editor-provider budget, and clears results with the document, project or plugin. Ranges are UTF-16. Actor panics are contained, queued work is rejected after a host panic, and diagnostics arriving after plugin cleanup are discarded. Verified on macOS with the diagnostics fixture.

A plugin web view can open a read-only editor tab that streams a process's output, with plugin-defined toggles, Find, wrap, zoom and Clear. The process is authorised in the backend against the exact granted `process:<program>` and its pinned executable, output is bounded, and the stream survives tab switches but ends when the tab closes, the plugin is disabled or the window closes. Adds a web-log test fixture and docs. Verified on macOS; Windows/Linux not run.

A plugin web view can open interactive PTY sessions (spawn, input, resize, kill, streamed output and exit). Spawning requires the exact granted `process:<program>` and its pinned executable, with no PATH re-resolution or fallback shell; the cwd is the trusted project, arguments, environment (append-only) and sizes are validated, and at most eight sessions run per plugin. A frame can only drive the sessions it opened; output is acknowledged chunk by chunk and input/output are bounded. Sessions end on permission change, reload, disable, uninstall, frame teardown or window close. Requires API ^1.3; adds a web-pty test fixture. Verified on macOS; Windows/Linux not run.

Closes#1950
Plugins can declare `detail = true` on a tree or list view (any tool-window side, grouped or not) to show the selected item's detail-provider tabs beside the list. The pane follows selection and refresh, clears stale content when the item, project or remote host changes, shows an empty state when nothing is selected, and remembers its resizable divider. Services keeps its single split. Released WIT and IPC shapes are unchanged. Verified on macOS in light and dark themes.

Closes#1951
Gutter markers only recognised a short alias list and the runtime truncated icon references at 32 bytes, so ordinary icon names and package paths were dropped. Markers now accept any built-in icon name, and API 1.3 `contributes.markerIcons` declares package SVGs (with an optional dark variant) that are size-limited, sanitised and rendered through the icon registry. The shared SVG sanitiser now also rejects URL strings in any CSS function (e.g. image-set), not only url(). Verified on macOS in light and dark themes.

Closes#1954
Plugin file templates could only take a typed name plus a fixed extension, so dot-files such as .dockerignore and templates needing more than a name weren't expressible. Templates (API ^1.3) can now declare a fixed `fileName` and named `variables` that the New File dialog asks for, and plugin templates get the same Java/Kotlin/Go/PHP package inference as built-in ones. Unsafe filenames and existing files are refused. The dialog no longer submits on Enter while an IME is composing, and its variable form has proper padding. Adds a file-templates test fixture.

Closes#1949. Plugin API 1.3: views from several plugins can share one tool window (shown as tabs) and a view can declare a visibility condition (e.g. only when the project contains a file, or for the active file) so it appears only when it applies. Additive within API 1.x, with a fixture plugin, regression tests and docs.

API 1.3 through the released `other` extension cases, no WIT change: form fields `label` (plain value) and `readonly-text` (selectable, optionally multi-line, drawn as read-only), and table view-events `table-select` / `table-activate` (click, Space; double-click, Enter) with absolute row indices. Table rows also get the view's `viewItem.context` commands, keyed by row. SDK: `FieldValue::label`, `FieldValue::readonly_text`, `ViewEvent::table_select` / `table_activate`. Closes#1953.

Adds the API 1.3 `endpoints-provider` export and `[[contributes.endpoints]]` (file globs, ^1.3, `project.read`). A plugin's routes join the Spring ones in Search Everywhere, `.http` URL completion and the declaration's Open in HTTP Client gutter action. The UI asks `plugin_endpoints` on demand; the host runs the plugin on a blocking thread, validates the whole list (bounds, project-relative locations, UTF-16 ranges) and caches it per project until a file matching the globs changes, then emits `EndpointsChanged`. A failed or invalid run keeps the last list; disabling, crashing or closing the project withdraws it, and late results can't restore it. Closes#1960.

Adds API 1.3 `ui.notify(level, title, body, actions) -> result<_, error>`: up to three buttons, each running one of the plugin's declared commands with an optional argument in the balloon's window and dismissing the balloon. An invalid action or an undeclared command fails the call and shows nothing. The plugin `Notification` event carries the actions; SDK `host::notify_with_actions` and `NotificationAction`. Closes#1955.
Co-authored-by: arnaud-ritti <[email protected]>
Adds API 1.3 `ui.pick-directory` (native folder chooser, same window/budget rules as `pick`) and `workspace.open-project(path, new-window)`, which goes through the normal File › Open flow with its trust prompt, window reuse and unsaved-change handling. Paths are absolute on the UI machine and validated by the host whatever its OS. Closes#1959.

A plugin title, label or message equal to IDE text ("Pick", "Log", "Refresh") was translated by the IDE catalog. Primitives now translate given text through useGivenTx, which returns it as written below VerbatimTextContext (plugin views, service panes, status items, prompts); plugin commands, tool windows, menu labels and notifications carry a verbatim flag. Command categories and the IDE's own words stay translated.
A plugin opts a table into click-to-sort by sending it as view body other(kind "table") with its sort; a header click comes back as view-event other(kind "sort", {column, descending}), so no released WIT type changes. The SDK builds and decodes both (Body::sortable_table, ViewEvent::sort). Headers are keyboard-operable, carry aria-sort and show the reported order with an arrow.

* feat(plugin): multi-line text input via ui.input-multiline
Adds host::input_multiline: a multi-line text dialog pre-filled with a
value, dismissed to none, confirmed with Cmd/Ctrl+Enter. Same rules as
input (command or event of a window, no capability, wait not charged).
Prompt::Input gains a multiline flag the frontend renders as a
textarea; the jobs fixture, SDK (wasm + mock), WIT and the plugin API
table are updated, and all plugin wasms rebuilt.
Fixes#1946
* chore: regenerate bindings after merging detail-provider rename
Context menu entries of a plugin can name a submenu on [[contributes.menus]] (editor, Project view, editor tab and view item menus; API 1.3): entries with the same submenu are grouped under it, a submenu with one visible entry stays a plain entry, and the label goes through the plugin's translations. Opt-in rather than by command category, since the category is the Find Action/keymap prefix and many plugins share one across all commands.

A plugin view declared with `location = "services"` (plugin API 1.3, `engines.openidea ^1.3`) shows its tree in the Services tool window, next to Docker and the run configurations. The nodes, the toolbar (acting on one selected node) and their events come from `view-provider`; `viewItem.context` menus give the nodes a right-click menu. The pane beside the tree comes from a new optional export, `service-provider.detail(view, key)` (worlds `plugin-services` / `services`), which returns typed tabs: a message, read-only text or a process log. The IDE switches tabs without calling the plugin.
For a log, the UI names only the node and tab (`plugin_service_log`); the host asks the plugin for the pane again and runs its program with the plugin's `process:` grant in the project root, with the arguments of the toggles that are on, streaming its output into the log pane Docker uses until it exits (the exit code is shown), the pane closes or the Services window is hidden. A cancelled request starts nothing, lines are cut at 16 KiB, and revoking the grant or cancelling kills the program and what it started. The log pane moves to `src/ui/LogPane` and drops output that arrives after its source was stopped. The Rust SDK gains `openidea_plugin::services` (`Services`, `Tab`, `Pane`, `ProcessLog`). All components are rebuilt for the WIT change.
Closes#1736

Plugin API 1.2 adds `ui.pick`, `ui.pick-many`, `ui.input`, `ui.confirm` and `views.reveal`. The dialogs show in the window whose command or event asked and block that call until the user answers; the wait is added to the call's deadline, so it doesn't use up the time budget. They need no capability and return `invalid` without a window (events without a client, rendering, editor providers). Prompts are withdrawn when the call is cancelled or the plugin stops, and reach remote windows through the dispatcher (`plugin_answer_prompt`). `views.reveal` brings one of the plugin's declared views to the front. The Rust SDK and its mock gain `pick`, `pick_many`, `input`, `confirm` and `reveal_view`. All components are rebuilt for the WIT change.
Closes#1768

Plugin API 1.2 adds `ui.set-context(key, value)` and `ui.remove-context(key)`: a plugin sets `plugin.<id>.<key>` for `when` clauses, typed as `context-value` (flag, number or text), in the window the call came from or every window outside a command or event; a window's value wins over the global one. Keys are 1-64 of `A-Za-z0-9_-`, at most 100 per plugin, kept across window reloads and idle reclaim, dropped when the plugin stops or the window closes; remote windows get them through the dispatcher. The Rust SDK takes `impl Into<ContextValue>`. All components are rebuilt for the WIT change.
Closes#1622

Plugin API 1.2 adds `invocation.selected-paths`: the files and folders a Project view or editor tab menu ran the command on, as absolute paths (the command's argument stays the first of them, so existing plugins see no change). The frontend passes the menu's selection to `plugin_run_command` on the desktop and through the remote dispatcher; the Rust SDK and its mock gain `Invocation::selected_paths`. All components are rebuilt for the WIT change.
Closes#1621

A plugin can declare `[[contributes.menus]]` with `menu = "viewItem.context"` and `view = "<its view>"`. Right-clicking an item of that tree or list view lists the matching commands, each run with the item's key as argument; `when` sees `viewItem` (the key) and `viewItemKind` (the key up to its first `:`). Validation refuses the menu without `view`, with an undeclared or web view, `view` on another menu, and (new in API 1.2) a manifest whose engines.openidea still admits older IDEs.
Closes#1618
Co-authored-by: arnaud-ritti <[email protected]>
A plugin can set `icon` (and `icon-dark`) in plugin.toml. The SVGs go through the existing sanitiser (16 KiB each), ship with the package, and show in Settings › Plugins (list rows and detail header) and the marketplace, whose index entries carry them; the IDE sanitises index icons again and drops unsafe ones.
IDEs before plugin API 1.2 refuse a manifest with `icon`, so Manifest::needs_api refuses one whose engines.openidea still admits them (check and install), keeping the index from offering such a package to older IDEs.
Closes#1732

Plugin when clauses can use workspaceContains:<path>, a path relative to the project root (any project of a workspace). Installation refuses empty, absolute and .. paths. The keys are re-checked on plugin changes, project switches, created or removed files and changes in ignored folders; plugins that don't use the key do no IPC. The key regex avoids lookbehind for WebKit.

The main toolbar gear's Theme submenu and Settings › Appearance › Theme preview the theme under the pointer after the same delay as Quick Switch Scheme, and closing without a choice brings the selected theme back. Choosing a theme while it was previewed left the preview flag on, so the start-up theme cache kept the previous theme; `setTheme` now ends the preview.
Import Theme from JetBrains IDE… lists one row per theme plugin and installs it without switching the theme, like any theme plugin install. It reads only the newest settings folder of each product, so folders left behind by upgrades don't list their plugins again.

Plugins get three host calls in API 1.1: vcs.remotes (under vcs.read) lists the
repository's remotes, ui.copy-to-clipboard and ui.open-url act on the window that
invoked the plugin's command.
Remote URLs are returned without the user:password part they may carry, and the
two UI calls fail when there is no invoking window instead of reaching every window.

The Available tab always showed a "There is no online plugin repository"
notice under the search field when no index was set. Release builds use
the official index by default, so the notice only appeared in development
builds, where the empty URL field above it already said the same thing.
The URL field itself sat at the top of the list although most people never
change it.
- The notice is gone, and the search placeholder reads "Search plugins"
because the list holds marketplace plugins as well as local ones.
- With a repository configured, the empty details panel says "No plugin
selected" instead of claiming there is no online repository.
- The marketplace index URL is edited from the gear menu's "Plugin
Repository…" dialog; leaving it empty restores the default.
* feat(plugins): list community plugins from a registry in the marketplace
The marketplace index can now carry plugins of other publishers, published
from their authors' repositories through the l0ng-ai/openidea-plugins
registry.
- `openidea-plugin index` with a key replaces only that publisher's plugins
(it used to drop every other entry); without a key it indexes each package
against the publishers the index already lists, checking the key and the
id prefix instead of only the signature itself.
- `openidea-plugin merge` takes another index's publishers, plugins and
revocations in place of every publisher but `--keep`; the other index can't
list or revoke the kept publishers' plugins.
- `openidea-plugin check` accepts a `.oiplugin` file.
- Releases merge the registry's index into plugins-index.json and attach the
Linux x64 tool; plugins-index.yml refreshes the community plugins in the
latest release hourly or when the registry signals a change.
- plugins/README.md and CONTRIBUTING.md describe official and community
plugins.
* feat(plugins): offer the newest plugin version this IDE can load
Index entries record the plugin API each version needs (`engine`: the
manifest's `engines.openidea` narrowed to the API its component was built
for), and an index may list several versions of a plugin. Settings › Plugins
offers the newest version this IDE can load; with none, the plugin is shown
as incompatible with the API it needs, and downloading it is refused.
`openidea-plugin index` keeps, of each plugin, the newest version per API
requirement, so users of an older IDE keep the last version built for them;
`--download-base` makes downloads absolute, and the release workflow points
them at the release that published them. Scratch directories are now unique
per call.
* feat(plugins): file marketplace plugins under categories
`plugin.toml` takes `categories` (up to 3 of languages, themes, icon-themes,
linters, vcs, ai, frameworks, tools, other). A plugin that declares none is
filed under what its contributions imply (themes, icon themes, languages),
else under other; categories an IDE doesn't know are ignored, and `check`
warns about them. Index entries carry the categories, and Settings › Plugins
› Available filters by them and shows them in a plugin's details. The
official plugins declare theirs.
* feat(plugins): let a marketplace index point to where it moved
An index with `moved` sends the IDE to the index at that URL (relative or
absolute, up to three hops; an https index can only move to https). Downloads
resolve against the index actually read, so a marketplace can change hosts
while released IDEs keep the address they were built with.
* fix(plugins): full-width category filter and aligned incompatibility note
* fix(plugins): translate the AI category in Chinese
* feat(plugins): keep a plugin's signer across updates and announce updates
- Index format: fields are only added; an IDE reading a newer `format`
still applies its revocations and `moved`, lists no plugins and asks to
be updated, instead of failing to read the index.
- Key continuity: an installed plugin updates silently only to a package
signed with the same key, or a key it endorsed (`KeyEntry.endorsement`,
`index --previous-key`, `openidea-plugin endorse`). Another signer, or an
unsigned package replacing a signed one, is shown on the install page and
needs the user's confirmation (`Consent.signerChange`).
- Official key: release builds carry the official publisher's public key
(`OPENIDEA_OFFICIAL_PLUGIN_KEYS`, derived from PLUGIN_SIGNING_KEY);
`openidea.*` plugins must be signed with it or a key it endorsed,
whatever the index lists.
- Updates: the daily marketplace check announces new versions once, with
Update All (also in the gear menu and as an action). An update that asks
for nothing new installs with the grants the installed version has.
- Index entries need `engine`; `categories` beyond the first three are
ignored instead of rejecting the manifest.
Settings › Plugins (gear menu) gets Import Theme from IntelliJ IDE… (theme plugins of the JetBrains IDEs on this machine, the one each IDE uses first) and Import IntelliJ Theme from File… (a Marketplace .jar / .zip or a .theme.json). The host reads the plugin with size limits; the UI converts it with the IntelliJ mapping (moved from scripts/theme to src/features/plugins/intellijTheme.ts, still used by pnpm theme:import-intellij) into one OpenIDEA theme plugin (engines.openidea ^1.0) with all of its themes, installed through the usual install page, and applies the chosen theme.
Theme pickers separate each plugin's themes, and Quick Switch Scheme › Theme previews the theme under the pointer or keyboard after 500 ms and restores the selected one when closed without a choice.

Icon themes could only map files by exact name or extension and folders by name. Themes can now match by regular expression or path (patterns that could backtrack badly, lookaround, inline flags and named groups are refused at install), ship dark variants, replace built-in UI and symbol (PSI) icons, and offer packs (groups) and variants (choices). A theme describes its own options page in Settings › Plugins as sections of items naming options the IDE implements (hide file/folder/UI/PSI icons, hollow folders, accent, monochrome, saturation, opacity, icon size, row height); values are stored per theme in appearance.fileIconThemeOptions. Existing themes are unchanged.

A plugin system built on WebAssembly components (wasmtime, WASI p2), with a
typed WIT API (`openidea:[email protected]`) and a Rust SDK, shipped as a preview.
- Extension points declared in `plugin.toml` (commands, languages, themes,
icon themes, menus, key bindings, status items, settings, views, custom
editors, file icons and templates, run detectors, editor providers),
validated before anything takes effect and projected onto the workbench's
own registries: plugin themes and file icon themes are chosen in
Settings › Appearance and Quick Switch, plugin shortcuts are edited in
Settings › Keymap, plugin problems are grouped in Settings › Inspections.
- Capabilities with risk levels and consent at install, pinned `process:`
programs, secrets in the OS keychain.
- Runtime: one thread per active plugin, fuel/time/memory budgets, soft and
hard deadlines on the editing path, cancellation, crash backoff, idle
reclaim, a precompiled-component cache; remote projects run code plugins on
`openidea-server`.
- Web views and custom editors with a sandboxed page, a document bridge
joined to the text editor's undo history, and split or preview layouts.
- Distribution: signed `.oiplugin` packages, a static marketplace index with
revocation, versioned installs with rollback, install from a `.zip` or a
folder. The release workflow signs and publishes the official plugins and
their index, which released builds use as the default marketplace.
- Official plugins: String Tools, Key Promoter, Git Toolbox, AI Completion,
Checkstyle, MyBatis Navigator, CSV Editor, Solidity, Material Icons, Harbor
Night, Excalidraw, Graphviz, Regex Tester, License Header.

Adds Solarized Light, Solarized Dark, One Light and One Dark as built-in themes across the workbench, editor, terminal and Mermaid, keeping the original palettes (MIT notices in THIRD_PARTY_LICENSES.md, mapping in docs/themes.md).
- Native window colours are read from tokens.css at build time (`theme_frame.rs`) instead of a second colour table.
- Startup restores the built-in palette before first paint.
- Editor schemes, the terminal and Mermaid refresh on switches between themes of the same kind.
- The plugin packages of the same themes are removed.
- A test requires every built-in palette theme to define each token (only listed ones may inherit from the base theme), so new tokens can't silently miss them.

Solarized Light/Dark and One Light/Dark ship as theme plugins (plugins/theme-solarized, plugins/theme-one) with complete UI tokens, editor schemes and terminal colours, and the original palettes' MIT notices. Installing a plugin now also copies its LICENSE/NOTICE/COPYING.
Theme handling that benefits every plugin theme:
- The last plugin theme is restored before first paint (splash, workbench); the native window background follows the theme.
- HSL / color-mix() / var() colours are resolved to RGB for native windows, the Settings window and Mermaid.
- Mermaid, the terminal and editor schemes follow switches between two themes of the same kind.
- An explicitly chosen editor scheme wins over a plugin theme's editor colours.
Supersedes #85.

Per the maintainer's decision for #24, no third-party themes are bundled; instead a theme plugin template and docs let the community port themes (IntelliJ also ships few themes, the rest are plugins).
- templates/theme-plugin: manifest-only plugin with an original example (Harbor Night) covering every UI token and an editor scheme (.icls equivalent).
- docs/plugins/themes.md: format, IntelliJ / VS Code porting tables, generated token reference (pnpm gen:theme-docs); drift test fails when tokens.css and the template/reference disagree.
- pnpm theme:import-intellij: dependency-free converter for IntelliJ .theme.json (+ .icls).
- Plugin host: themes may name an editor-scheme merged over the theme; comments allowed in theme files.
- Fixes: a plugin theme's kind now switches the light/dark base; plugin themes go in their own stylesheet so the Appearance accent and editor scheme still layer on top.
Verified: ide-plugin tests, vitest (44), in-app on macOS: installed the template from disk, applied Harbor Night (dark base + teal accent over Islands Light), back to default restored the light theme.
