[opencode][Linux] default player pw-play will not play anything due to l10n issues for LANG=de

[enolive]

I installed the main peon cli via

curl -fsSL https://raw.githubusercontent.com/PeonPing/peon-ping/main/install.sh | bash

I also installed the OpenCode adapter via

curl -fsSL https://raw.githubusercontent.com/PeonPing/peon-ping/main/adapters/opencode.sh | bash

the sound playback works perfectly in both the Terminal and Claude CLI

unfortunately, the sound setup does not work in the Plugin

after some for and back I found out that the plugin uses pw-play for its setup

and for some reasons this CLI tool honors the current LANG settings in the Terminal for its volume control ;-)

in Germany and many other countries, point is used as a thousands separator while comma is used for fractional numbers.

tbh, I did not suspect a CLI tool to pick up something like that.

example:

> echo $LANG
de_DE.UTF-8
# won't play anything
> pw-play --volume '0.5' /home/chris/.openpeon/packs/peon/sounds/PeonAngry1.wav
# will play the sound file
> pw-play --volume '0,5' /home/chris/.openpeon/packs/peon/sounds/PeonAngry1.wav
# will also play the sound file
LANG=en pw-play --volume '0.5' /home/chris/.openpeon/packs/peon/sounds/PeonAngry1.wav

I suggest that you set the env variable when executing the CLI commands for playing sounds to minimize confusion with international users.

For now, I just changed the volume in the peon-ping plugin config to "0,5" 😉

{
  "default_pack": "peon",
  "volume": "0,5",
  "enabled": true,
  "....
}

update:

   const proc = Bun.spawn(args, {
            stdout: "ignore",
            stderr: "ignore",
            env: {
              ...process.env,
              LANG: "en"
            }
          })

seems to work

apparently, peon.sh is using LC_ALL=C for the same call ;-)

Good catch, and thanks for the detailed investigation! This is exactly the same issue we already handle in peon.sh — we set LC_ALL=C before calling pw-play there for the same reason.

The fix needs to land in the opencode plugin (adapters/opencode/src/peon-ping.ts or the Bun spawn call) so that LANG / LC_ALL is normalized to a decimal-safe locale when spawning the audio player.

Logging this as a bug fix for the opencode adapter. Setting LANG=en_US.UTF-8 or LC_ALL=C in the env passed to Bun.spawn (as you found) is the right approach. Will get this patched.

This is actually fixed by the merge of #430 (just landed). The OpenCode adapter is now a thin wrapper that routes all sound playback through peon.sh, which already normalizes the locale via LC_ALL=C before calling pw-play. No separate fix needed in the TypeScript plugin. Thanks for the detailed investigation, enolive!
