Add bundled Emacs and Windows keybinding presets - #86
Conversation
Adds a `keybindings.preset` setting ("default"/"emacs"/"windows") backed
by bundled JSON assets under core/keymap/presets/, resolved through a
new never-throwing loader and layered into the binding table as a fifth
`preset` layer.
Correction from the original plan: `preset` is placed ABOVE `extension`
(not between `defaults` and `fallback`) in LAYER_ORDER. Verified by
direct probing that a lower-precedence layer's `-command` removal cannot
mask a higher-precedence layer's binding — with the originally-planned
order, the Emacs preset's removal of keybindings-editor's unconditional
`ctrl+k ctrl+s` chord would have been silently inert, leaving `ctrl+k`
permanently shadowed as a chord prefix (chords.ts's "prefix wins" rule)
and the preset's own kill-line binding unreachable. Mutation-tested: both
the chord-shadowing fix and the precedence tests fail under the reverted
LAYER_ORDER/reverted removal, confirming the guards are load-bearing.
The `keybindings.preset` config value is applied and live-reloaded via a
new cli-local `keybindingPresetConfigSync.ts`, mirroring
`workbench.colorTheme`'s `applyConfiguredTheme`/`wireThemeConfigSync`
pair (kept out of `@tecode/core` since `KeymapState` is cli-local).
No vim preset, per the issue author's explicit scope narrowing.
Adds Req 4.8 and design.md §6.6; documents both presets and the setting
in README.md and samples/settings.json.

design.md §6.2 and requirements.md Req 4.1 both still described a three-layer table — defaults, extension, user — which contradicted the new preset layer AND silently omitted the terminal-capability fallback overlay that has existed since Task 4.2. Read together with §6.5 and §6.6, the precedence was no longer uniquely determined. Both now state defaults < fallback < extension < preset < user, and §6.2 records why the ordering is load-bearing rather than cosmetic: override and removal-masking are both order-directional, so a layer can only cancel or beat one below it.

#86 added root.keybindingPresetConfigSync.dispose() to the inline shutdown list that this branch replaces wholesale with createShutdown, so git could not merge the two: taking either side alone silently drops one change. Resolved by keeping both — createShutdown's shared, memoized, timeout-bounded sequence, with keybindingPresetConfigSync folded into ShutdownRoot and the teardown list, plus #86's applyConfiguredKeybindingPreset() call retained at its assembly point. Without the former the preset's ConfigService subscription would leak on every quit. The disposable-count assertions move 18 -> 19. That count is what makes a dropped dispose fail rather than pass silently: removing the new line fails both idempotency tests.

Completes #81, stacked on #85 (
--configflag) — merge #85 first; this PR targets that branch, and its base will retarget tomainonce #85 lands.Issue #81 asks for example keybinding files. vim is deliberately not included — the issue named it, but the repository owner dropped it. For the record: vim's value is modal editing, and tecode has no mode concept (the
whencontexts are focus-based only —editorTextFocus,editorFocus,quickPickFocus,inputBoxFocus,findWidgetFocus,explorerFocus,editorLangId), so a non-modal "vim" preset would have been misleading rather than useful.What changed
Bundled JSON presets under
packages/core/src/keymap/presets/, selected through a newkeybindings.presetsetting (default"default", i.e. no preset), composed as a newpresetbinding layer and live-reloaded on config change with no restart — the same mechanismworkbench.colorThemealready uses. Static JSON imports put the assets in the compiled binary, followingfallbackKeybindings.ts's precedent.The layer order had to change, and that is the interesting part
The plan (and my own instruction to the implementer) specified
defaults < preset < fallback < extension < user. That cannot work, and the reason is worth recording.bindingTable.ts'svisibleEntriesmasks only entries with a strictly lower order than a-commandremoval. Order increments inLAYER_ORDERsequence, so a removal in thepresetlayer can only cancel bindings from layers earlier in that list. Withpresetbelowextension, a preset could never remove an extension's binding — and could never override one either, which would make bundled presets largely pointless.The order is now
defaults < fallback < extension < preset < user. A preset outranks extension bindings (the user explicitly chose it; the extension did not), and the user's ownkeybindings.jsonstill outranks the preset. Documented inbindingTable.ts'sKeymapLayersTSDoc and design.md §6.6.The
ctrl+ktrapkeybindings-editorbinds the chordctrl+k ctrl+s, andchords.ts'shandleIdleStrokecheckshasSequencePrefixunconditionally before the exact-match lookup ("prefix wins", design.md §6.3). So an Emacs preset that simply addsctrl+k→ delete-line would leave the editor waiting for a second keystroke instead of killing the line — one of Emacs's most-used keys, silently dead, and it would have looked fine in review.The Emacs preset therefore carries
{ "key": "ctrl+k ctrl+s", "command": "-keybindings.open" }, which is exactly why the layer-order correction above was required.The test presses the real
ChordStateMachine(handleStroke("ctrl+k")) and asserts direct execution ofeditor.action.deleteLinewith no pending chord state — asserting the entry merely exists in the table would not have caught this. A sibling test proves the hazard is real without the preset.Preset contents
Emacs (all
when: "editorTextFocus"):ctrl+a/ctrl+eline start/end ·ctrl+f/ctrl+b/ctrl+n/ctrl+pcursor right/left/down/up ·alt+f/alt+bword right/left ·ctrl+kkill line ·ctrl+sfind (isearch) ·ctrl+x ctrl+ssave.Three collisions are deliberate and documented:
ctrl+fover editor-core's find,ctrl+sover its save, andctrl+pover the command palette's quick-open. All three are scoped toeditorTextFocus, so they fall through to the default behaviour everywhere else. Undo/yank-ring bindings were deliberately skipped — there is no kill-ring concept to back them, andctrl+/would collide with toggle-comment.Windows is genuinely thin, and the README and loader TSDoc say so rather than padding it: the default keymap is already VS Code–shaped. The real divergence is that move-lines is bound to
alt+meta+up/alt+meta+down(meta = Cmd, a macOS idiom), so the preset addsalt+up/alt+downalongside them, plusshift+alt+downfor duplicate-line.Tests
42 new or adjusted tests, including one asserting that every command id referenced by every preset actually exists, derived from the exported id constants rather than retyped — a typo there would be a silently dead binding.
