Describe your issue

micromamba is supposed to support csh, but when attempting to initialize the shell you get an error saying that csh is not a shell choice:

micromamba activate chemprop

'micromamba' is running as a subprocess and can't modify the parent shell. Thus you must initialize your shell before using activate and deactivate.

To initialize the current csh shell, run: $ eval "$(micromamba shell hook --shell csh)" and then activate or deactivate with: $ micromamba activate To automatically initialize all future (csh) shells, run: $ micromamba shell init --shell csh --root-prefix=~/micromamba If your shell was already initialized, reinitialize your shell with: $ micromamba shell reinit --shell csh Otherwise, this may be an issue. In the meantime you can run commands. See: $ micromamba run --help

Supported shells are {bash, zsh, csh, xonsh, cmd.exe, powershell, fish}. critical libmamba Shell not initialized

micromamba shell init --shell csh --root-prefix=~/micromamba_csh --shell: csh not in {bash,cmd.exe,dash,fish,posix,powershell,tcsh,xonsh,zsh} Run with --help for more information.

Then if trying to use tcsh instead you get another error: micromamba shell init --shell tcsh --root-prefix=~/micromamba_csh critical libmamba Support for other shells not yet implemented.

This indeed looks like a bug. Thanks for reporting!

The micromamba.csh script fails in csh or tcsh due to the line:

set ask_conda="\(setenv prompt "${prompt}"; __mamba_exe shell "!*" --shell csh)`"`

With error:

Unmatched '''.

Sadly, while I hate using csh or tcsh, preferring zsh or at least bash, many of my colleagues need to run in csh due to legacy tools. Not having a workable micromamba executable is annoying.

I'd suggest refactoring micromamba.csh to avoid battleship aliases with four levels of quoting, which csh handles so poorly. Apologies, I don't have the cycles right now to contribute a fix.
