zsh option completions broken in 0.0.8

[kubukoz]

scala-cli run --<tab>, scala-cli compile --<tab> and scala-cli compile -<tab> all result in the following:

…(eval):2: command not found: dev
(eval):2: command not found: release
clang: error: no input files
(eval):2: command not found: .pipe…
(eval):2: command not found: -1

screenshot:

This is in zsh on Mac, completions file was generated with scala-cli completions zsh.

Bash completion is very broken as well. I can open a separate issue but I imagine the root cause is likely the same.

Result of me simply typing scala-cli <Tab>:

$ scala-cli -bash: --: command not found
sh: _pyenv_virtualenv_hook: command not found
sh: _direnv_hook: command not found
sh: prompt_func: command not found
sh: autojump_add_to_database: command not found
sh-3.2$

What this has done is apparently execute /bin/sh…

Also e.g. scala-cli install completions <Tab> executes writing to my ~/.bashrc immediately as though I had hit Enter…

scala-cli --scal<Tab> spews mangled output of scalac -help for --scala-opt:

I have a feeling the changes like this have resulted in all the backtick-enclosed text in help messages getting interpreted by the shell… improper shell escaping somewhere.

Thanks for reporting @kubukoz and @ches,

The problem was that the backticks wasn't escaped. It was already fixed and in the next version of scala-cli 0.0.9 competition should work.

I added escaping backticks in bash/zsh completion in case-app. It was done in this PR.
