調査の方向性

Start with scripts/prepare-ripgrep.ts, desktop/scripts/build-sidecars.ts, and desktop/electron/main.ts to trace where the development binaries are written and launched. Then read desktop/electron-builder.json and the two CONTRIBUTING guides to check the packaged layout and documented paths. Update the paths to use a triple-named directory, add or update the requested path tests, and verify the macOS and Windows package layouts.

説明

area:desktop bug difficulty:2 good first issue help wanted

Problem

In dev mode (bun run electron:dev), search tools such as Glob and Grep can fail with:

ripgrep is not available. Install ripgrep and ensure rg --version works in this environment.

The installed app is not affected. Whether dev mode works depends on whether a real rg happens to be on the PATH of the shell that started it. For example, it works when started from a Codex shell, because Codex adds its own rg to PATH, and fails from a shell without one.

Cause

The dev layout of desktop/binaries differs from the packaged layout:

Sidecar ripgrep
Dev (desktop/binaries/) dreamcoder-sidecar-aarch64-apple-darwin rg-aarch64-apple-darwin
Packaged (Resources/bin/) dreamcoder-sidecar rg

At runtime the CLI looks for a file named rg next to its own executable (src/utils/ripgrepConfig.ts:29). In the packaged app that file exists. In dev mode it is named rg-<triple>, so the lookup fails and falls back to the system PATH.

The vendor/ripgrep/<platform>/rg fallback (src/utils/ripgrepConfig.ts:33) does not help either. Inside the compiled sidecar, sourceRoot is derived from import.meta.url, which points into Bun's embedded filesystem rather than the checkout.

The target-triple suffix is left over from Tauri, which required it for external binaries. Electron does not need it.

Proposed fix

Make the dev layout match the packaged one, with the triple as a directory instead of a file-name suffix:

desktop/binaries/<triple>/dreamcoder-sidecar[.exe]
desktop/binaries/<triple>/rg[.exe]
  • scripts/prepare-ripgrep.ts (around line 132) copies ripgrep to binaries/<triple>/rg[.exe].
  • desktop/scripts/build-sidecars.ts (line 31) writes the sidecar to binaries/<triple>/dreamcoder-sidecar.
  • desktop/electron/main.ts (line 109) starts the dev sidecar from binaries/<hostTriple>/dreamcoder-sidecar[.exe].
  • desktop/electron-builder.json copies binaries/<triple>/ to bin/ for each platform, instead of renaming the two files one by one (lines 52-57 for macOS, 92-97 for Windows).
  • Update the path in docs/CONTRIBUTING_en.md and docs/CONTRIBUTING_zh.md (line 155).

Keeping the triple as a directory means a cross-target build with DREAMCODER_TARGET_TRIPLE still does not overwrite the host build.

Please don't teach ripgrepConfig.ts to look for rg-<triple>. That would put build-script naming into the CLI's runtime lookup for the sake of dev mode only.

How to check

  • With no rg on PATH (for example PATH=/usr/bin:/bin), run bun run build:sidecars and bun run electron:dev. In a session, a Glob or Grep call returns results.
  • Add or update tests for the new paths in prepare-ripgrep and the dev sidecar path.
  • bun run electron:pack on macOS still puts dreamcoder-sidecar and rg side by side in DreamCoder.app/Contents/Resources/bin/. Windows needs the same check for the NSIS build.
  • Existing checkouts need one more bun run build:sidecars. The old suffixed files in desktop/binaries/ can be deleted.
