Using bash from HomeBrew

[leshik]

Is there any reason not to use /usr/bin/env bash instead of /bin/bash?
macOS uses an old version of bash3, and I use bash5 from HomeBrew. Some tools have completions that use complete -o nosort -o nospace -o default -F ... and nosort option doesn't work in bash3, resulting in plugins failure.

Honestly, I can't come up with a reason why not to switch to /usr/bin/env bash 🤔

[melonamin]

Addedd a separate option in Preferences, try beta

@melonamin Doesn't work for me for some reason. I.e. the shell used is still system's bash, not the one from HomeBrew despite I have it set in system preferences.

The latest beta build works for me.

@leshik can you post a screenshot of the dropdown menu using the following plugin?

echo 'foo'
echo '---'
echo $PATH
echo $(which bash)

[leshik]

@xilopaint The problem is, I can't even run any script because it fails earlier failing to load /usr/local/etc/bash-completions.d as scripts there have some features that are incompatible with Bash v3.

What error message do you get?

My bet is you're based on the wrong assumption that SwiftBar is still running the system bash. The message suggests the script expects a Terminal (maybe calling tmux?) but SwiftBar is not a Terminal. You can try disabling tab completion and running the plugin I recommended to check your actual shell.

@xilopaint There are 2 errors here, and I'm talking about the first one, i.e. nosort: invalid option name, which is resulted from an incorrect Bash version. To confirm this, I edited /usr/local/etc/bash_completion.d/ipfs-completion.bash, commented the line 5259 (which is the last one in this file), and added echo $BASH_VERSION > /tmp/bv.txt there. SwiftBar has bash(env) as a shell selected. Here are the results:

$ cat /tmp/bv.txt
3.2.57(1)-release

Meanwhile:

$ /usr/bin/env bash -c 'echo $BASH_VERSION'
5.1.16(1)-release

@leshik I reworked this a bit, please try again using default as the shell in SwiftBar Preferences BETA 4

[leshik]

@melonamin no, not working - same issue

[melonamin]

Can you do a quick test for me please?

Run a plugin like this(I'm on mobile, can't test it):

!#/bin/env bash

echo "Test"
echo "---"
echo $SHELL
echo $0
ps -p $$

And show me the output please.

@melonamin as I described in one of my previous comments, I can't run this script as a plugin as the actual error happens prior to any plugin being executed, this my only option was to edit the HomeBrew completion file that causes the error, and insert your code there before the command that fails. Anyway, the results are interesting:

[melonamin]

Ok, plz help me reproduce your setup on my end, I need to:

1. install bash from brew brew install bash
2. change my default shell to freshly installed bash chsh …
3. install custom bash completions(???)
4. …
5. It should be as broken as yours

Correct? What should I do at step 3 and what is missing?

[leshik]

@melonamin brew install bash ipfs (ipfs is the package whose completions cause the issue)
chsh or just set the default shell for a user in UI (Users - Advanced options)

[melonamin]

Ok, I replicated the environment and combination of this plugin and this build seems to be working correctly on my end.

#!/usr/bin/env bash

echo "Test"
echo "---"
echo $SHELL
echo $0
ps -p $$

@melonamin I don't know how else I could help to troubleshoot this. I'm on Intel Mac if it matters (I see yours is ARM), though not sure if it makes any difference.

@melonamin while experimenting I somehow screwed the settings, and now I can't access SwiftBar UI at all (though I can see it running in processes). I tried to delete settings, plugins, and restart – but it didn't help. How can I reset SwiftBar to the default state?

[melonamin]

Nuking ~/Library/Preferences/com.ameba.SwiftBar.plist should be enough, but here is the full list of files and folders created by SwiftBar:

@melonamin something weird is happening now with this build. The test plugin only works when the shell is set to zsh. Selecting default results in no output at all (then it's not even possible to access settings), and selecting bash draws ⍰ in the bar, but now it doesn't even matter if I comment complete -o sort ... option in bash completions – it doesn't work in any case.
