Part of #81 (does not close it — the keybinding presets are a separate change).

Issue #81 asks for config-file support: 「起動時に指定するほか、デフォルトで読み込まれる設定ファイルをホームディレクトリ以下に用意してほしい」. The home-directory default already existed and worked (~/.config/tecode/settings.json and keybindings.json, resolved by host/paths.ts); what was missing is the startup override.

What changed

--config <dir> names a config directory, and both settings.json and keybindings.json are derived from it.

  • cli/argv.ts gains resolveConfigDirOverride(argv) — pure, synchronous, never throws, degrading to undefined when the flag is absent or has no following value, matching the module's existing policy.
  • core/config/service.ts's ConfigServiceDeps gains optional settingsPath / keybindingsPath, defaulting to deps.settingsPath ?? getUserSettingsPath() and the keybindings equivalent. This follows the established convention used by ui/themeSettingsWriter.ts and ui/keybindingsCommands.ts: the consumer overrides, and paths.ts stays a plain default helper with no environment-variable branching of its own.
  • cli/main.ts parses the flag at the same early position --version is handled and threads it through RunTecodeOptions into buildAssemblyRoot's createConfigService call.

The override applies to the user layer only. Workspace settings (.tecode/settings.json) resolve exactly as before.

The positional-argument hazard

tecode ./src opens ./src, so the positional scan had to learn not to swallow --config's value. resolveStartupTarget and resolveConfigDirOverride now share one findConfigValueIndex helper so both agree on precisely which token is the flag's value, and the scan skips that index.

Without it, tecode --config /tmp/cfg would have opened /tmp/cfg as the workspace — silently doing something quite different from what was asked.

Verification

Independently mutation-tested in three directions, each restored afterwards:

  • Neutralising deps.settingsPath ?? … → the end-to-end buildAssemblyRoot test and the ConfigService unit test both fail.
  • Neutralising deps.keybindingsPath ?? … → the corresponding pair fails.
  • Dropping index !== configValueIndex from the positional scan → both argv positional tests fail.

That matters here because a flag can very easily be threaded all the way through and still not take effect. The main.test.ts cases build a real buildAssemblyRoot against a temp HOME and assert the --config directory's settings.json and keybindings.json genuinely change behaviour, rather than asserting the string arrived somewhere.

Specs and docs

requirements.md gains the new criterion, design.md documents the flag, and README.md covers it in the configuration section.

Validation

bun test 1587 pass / 1 skip / 0 fail, bunx tsc --noEmit clean, bun run lint clean. Rebased onto current main (includes #83's editor-focus fix).

Lets tecode read the user settings/keybindings layer from a caller-chosen
directory instead of the home-directory default, without disturbing the
workspace settings layer. argv.ts gains a pure resolveConfigDirOverride
parser and resolveStartupTarget now skips --config's value when scanning
for the positional file/directory argument. ConfigService accepts optional
settingsPath/keybindingsPath overrides (same deps.path ?? getUserXPath()
convention as themeSettingsWriter/keybindingsCommands), and main.ts derives
both paths from --config's directory and threads them through
buildAssemblyRoot/RunTecodeOptions.

Merge Risk: 🔵 Low · up to 1782f

Repeated --config flags can cause a later configuration directory to be opened as the workspace instead of being ignored as another flag value. The change is otherwise bounded, but this edge case should be corrected or explicitly accepted before merge.

Comment thread packages/cli/src/argv.ts Outdated
findConfigValueIndex used argv.indexOf, so only the FIRST --config's value
was excluded from the positional-argument scan. A repeated flag's value
was left looking like a bare positional, so

    tecode --config /a --config /b

silently opened /b as the WORKSPACE — a different thing entirely from what
was asked.

Which --config wins is a separate question from which tokens are values:
the override still takes the first occurrence, matching this module's
"first token wins" treatment of the positional argument, but every
occurrence's value is now excluded from the scan.

Mutation-verified: reverting to first-occurrence-only fails the new test.
