Error test: Missing argument at index 2 with virtualfish

[edouard-lopez]

After installing virtualfish and customizing my fish_prompt as shown in the documentation with my omf theme pure I got error:

test: Missing argument at index 2

I tried with another theme (flash) and got event more error.

steps

I edited the fish_prompt as follow:

funced fish_prompt
# add lines, then save and quit vim
funcsave fish_prompt
# Ctrl+D to quit tmux tab
# open new tab, get the error

Question

How can I solve this issue?

@edouard-lopez: there are other themes that support virtualfish, such as bobthefish and scorphish. If you wish to have current active virtualenv in your pure prompt, just make it look like this.

@rafaelrinaldi: even this being a port from a ZSH theme, maybe you'd like to add support to virtualfish, a pull request is on the way 😄

[rafaelrinaldi]

@scorphus We want to stay consistent with the original theme. You can add to your custom settings anyway.

[rafaelrinaldi]

@edouard-lopez Isn't there a way to simply bypass this check? Not sure how to do it but ideally the theme shouldn't bitch about it.

[edouard-lopez]

Solved by editing ~/.config/fish/functions/fish_prompt.fish and adding the following:

  if set -q VIRTUAL_ENV
    set prompt $prompt "$color_gray("(basename "$VIRTUAL_ENV")")$color_normal \n"
  end

Seem the funced fish_prompt was not the correct way to do it.

However this is not reinstall-proof…
