Support $env:EDITOR being a .bat/.cmd script on Windows #1882
Description
Activity
Thx for filing this issue - I also stumbled over it today when trying to configure VS Code
Cross-referencing anthropics/claude-code#57215 — same root cause in another major Windows TUI consumer.
Since Node 18.20.0 / 20.12.0 / 21.7.0 (CVE-2024-27980, April 2024),
child_process.spawn('<file>.cmd', ...)synchronously throwsEINVALunlessshell: trueis passed. A one-line fix on the Ctrl+G launch path covers.cmdand.battogether without per-extension logic:// instead of: spawn(editor, args) spawn(editor, args, { shell: true }) // or, with explicit dispatch: spawn('cmd', ['/c', editor, ...args])
(Anthropic's
claude-codeLSP-spawn paths got this same fix for the same root cause: anthropics/claude-code#27061, #51191, #53814.)Worth re-framing this as a bug rather than a feature request — npm-installed editors always end in
.cmdon Windows, so any global npm bin used as$EDITORerrors out withError: spawn EINVALon Node ≥ 18.20.0.thanks for filing an issue, I have the same problem, do we know what is their cadence in terms of fixing and releasing new version.
This appears to be resolved as of GitHub Copilot CLI v1.0.85. Please update to that release or a newer stable version. We're closing this as completed. If it still happens, please comment with your version and reproduction steps.
Describe the feature or problem you'd like to solve
I would like to use an external editor via Ctrl-G. My external editor is opened via a wrapper Batch script
Proposed solution
Support external editors that are started via Batch (.bat/.cmd) scripts on Windows.
Example prompts or workflows
Additional context
Today, GitHub Copilot CLI does not support your external editor being a Batch (.bat/.cmd) script. If your
$env:EDITORis something like "my-editor.cmd", pressing Ctrl-G fails with "Error: spawn EINVAL".If
$env:EDITORis an executable, it works fine.
