Arch Linux User Repository

For everyone having build issues with the shell completion, follow the following steps:

• Remove your ~/.copilot/pkg folder
• Clear your AUR helper cache
• If using makepkg, use -C

That should solve your problem. However, if the issue persists, build your package in a clean chroot environment.

There aren't problems with packaging, and nothing will be changed on our side, so avoid commenting on a problem that has already been discussed many times. Thanks!

It looks like the build failure may be related to npm install fetching the optional dependency @github/copilot-linux-x64 from the internet during packaging. If this optional native binary gets installed, it appears to take precedence over the JS fallback (index.js). The native binary in the current release does not seem to expose a completion subcommand, while the JS fallback does.

This could explain why the build succeeds in some environments but not others — in environments where npm skips the optional dependency (e.g. due to network restrictions in certain chroot setups), the JS fallback is used and the build succeeds.

It may also be worth noting that the PKGBUILD appears to trigger an undeclared network fetch during package() for this optional dependency, which is not listed as a source with a checksum.

The failure has now been reproduced by multiple users across 1.0.39 and 1.0.40, both with AUR helpers and with plain makepkg. Could you share the exact steps to reproduce your successful build, including how your chroot environment is set up? That would help narrow down why it behaves differently in your environment.

Unfortunately, building this fails:

Again, please build in a clean chroot environment; it builds correctly. If you're having issues, it's a problem with your AUR helper.

Build fails in 1.0.39: autocompletion generation broken

The build fails during Generating autocompletions for Bash/Zsh/Fish because
copilot completion <shell> is not a valid command in the native binary shipped with 1.0.39.

The copilot wrapper (npm-loader.js) prefers the bundled native ELF binary
(@github/copilot-linux-x64) over the JS fallback (index.js). The native
binary in this release does not expose a completion subcommand, even though it
exists in index.js.

Fix: invoke node index.js directly for the three completion steps:

Build in a clean chroot, the packages were tested there and they work

I think the most recent PKGBUILD update adding autocompletions has some bad syntax. Getting this error:

Thanks for adding the completion files! But I think the completion file for fish should be in /usr/share/fish/vendor_completions.d/ directory, because /usr/share/fish/completions/ is populated by the fish package itself.

You can see for example in the ripgrep package https://archlinux.org/packages/extra/x86_64/ripgrep/files/

Also, I don't think -s does anything when running npm install -g so you might as well remove it. If it does do something, by all means keep it.

Can this patch be considered?

Both the README.md and LICENSE.md are getting properly extracted from the npm package without issues, and I compared them with the ones initially downloaded, and there's no difference but some cosmetic identation some places. So there's no real purpose on getting those, and we're compliant on getting them and explored before even getting installed
