bat - filename completion script issue with init_completion error

[maximillianus]

When I try to do autocomplete for the filename when using bat, I encounter init_completion issue. This happens in iTerm2. Strangely, in my regular terminal, it works fine. It happens the same to my regular terminal.

Let's say I am trying to use bat to check package.json.

This is what comes up after I click after typing bat pac

bat pac-bash: _init_completion: command not found

...

I would expect filename auto completion works fine in iTerm2 as it does in regular terminal.

...

I install bat using homebrew and using it on iTerm2.

iTerm version: iTerm2 Build 3.4.15

Just in case anyone sees this and doesn't click through to the linked PR, I found out I had bash-completion version 1.3 installed and bat is expecting 2.

I use homebrew, so I uninstalled bash-completion installed the formula bash-completion@2 and that works fine. If you use another installation method, then maybe check your bash-completion version and upgrade if you can. If the linked PR lands, then it should work with both versions in the future.

Thanks @myobie . This works for me. I uninstalled my bash-competion and installed bash-completion@2. Then I spawn a new terminal window and it works. It doesn't work when I immediately in the current terminal window, but that's minor.

@Enselic Are you sure you wanted to close this one? I'm suddenly getting a very similar behaviour from bat 0.20.0 (homebrew install on macOS 12.2):

Attempting to show the contents of .bash_profile, hit tab after typing bat .bash_p and I get:

$ bat .bash_p-bash: _split_longopt: command not found
-bash: _filedir: command not found

(Edit to add: I already had bash-completion@2 installed.)

Thank you for reporting. Why call it "very similar" though? Looks like a different issue.

Would be great if you or someone else can reproduce this on another machine. If so, it would be great if you could report it as a separate issue.

Filed #2147 for this related issue, as I believe it was the fix that introduced my issue.

For anyone else coming to this issue: replacing bash-completion with bash-completion@2 does solve the errors, but keep in mind bash-completion@2 requires bash version 4. If you use bash 3 (the default on even the latest macOS), you can't use bash-completion@2, which means you can't use bash completions at all for bat. So, just remove it (i.e., rm /opt/homebrew/etc/bash_completion.d/bat). (Yes, I know I can upgrade to bash 4 easily; I use bash 3 because I want to write and test scripts for use on other macOS computers that still use bash 3.)
