Description

Most functionality is broken (building, flashing, etc.). I think it is a small problem though.

When I click "View->Output->ESP-IDF", I am greeted by this:

~/.espressif/tools/activate_idf_v5.5.3.sh (line 14): Unsupported use of '='. In fish, please use 'set _EIM_BIN "$(command -v eim 2>/dev/null || true)"'.
_EIM_BIN="$(command -v eim 2>/dev/null || true)"
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
warning: Error while reading file /Users/ajcd2020/.espressif/tools/activate_idf_v5.5.3.sh

This message still appears when I tried to change "vscode-insiders://settings/idf.customTerminalExecutable" to "/bin/bash" (with and without setting "vscode-insiders://settings/idf.customTerminalExecutableArgs" as "-c").

I still get this message even after changing my system shell to bash with chsh -s.

It might also be causing this issue: when I open the example project, a notification will pop up with this message:compile_commands.json is missing. This may cause errors with code analysis extensions.

When I click the button (generate compile_commands.json) I get this message: Illegal argument: process

Debug Message

Please take a look at espressif/idf-im-ui#542 for fish support.

We initially intended to support PowerShell and Bash mostly but if you enable fish on the whole system it would break the bash setup too. PTAL at the PR artifacts or wait for the next stable release of EIM.

It looks like espressif/idf-im-ui#542 was merged and a new version was released.

I reinstalled IDF v5.5.3 and I now see the following script: ~/.espressif/tools/activate_idf_v5.5.3.fish.

But, I still have the same error appearing in VSCode.

~/.espressif/tools/activate_idf_v5.5.3.sh (line 15): Unsupported use of '='. In fish, please use 'set _EIM_BIN "$(command -v eim 2>/dev/null || true)"'.
_EIM_BIN="$(command -v eim 2>/dev/null || true)"

I think the extension needs an update to look for the fish script when appropriate.

Also getting this on macOS 26 with ESP-IDF 6.0. For now I've worked around it by changing my terminal profile to bash in VSCode, which I don't like but it's certainly better than changing my login shell.
