Is it possible to call bash functions?

[nkabir]

Does plumbum support accessing bash functions in addition to bash commands?

Also stumbled across this today. The function is available and callable from the terminal, but when trying to call it with plumbum I get a CommandNotFound error.

A good example is declare (bash builtin):

which declare
/usr/bin/which: no declare in 

declare X=Y
echo $X
>> Y

from plumbum import local
declare = local["declare"]

→ plumbum.commands.processes.CommandNotFound: ('declare', ....

The limiting code is in https://github.com/tomerfiliba/plumbum/blob/master/plumbum/machines/base.py#L51

For bash functions to work, one would probably need to introduce a new Path specialization.

A workaround is to use a dispatch shell script (e.g. dispatch.sh):

#!/usr/bin/env bash

readonly TARGET_FUNCTION="${1:?missing target function}"
shift
eval ${TARGET_FUNCTION:?} $@

Then

>>> dispatch = local["./dispatch.sh"]
>>> dispatch["mybash_func"].run_fg()
