get stdout of hilbish.run

[AlphaTechnolog]

Hello! :wave:

I'm trying to make support to the git branch in my prompt, but i tried using hilbish.run and trying to get the stdout and don't works :c

here is my code:

local function get_git_branch()
    local status, stdout, stderr = hilbish.run('git branch', true)

    if stdout ~= "" then
        return stdout
    end

    return nil
end

but that function always returns nil, and print the stdout in the terminal without catching it in my variable, here is the demonstration:

Idk if i'm doing smth wrong, please tell me if i'm doing something wrong lol

you are using the function correctly and it also works on my end. you have to be using at least commit 0fc5f457adf1c8d8b8fefc94ab9d940cacb275b6 for stdout/stderr returns

and for this usage specifically, here is how delta does it, which is my own prompt

ah lol, well now i tried with this code, and seems that it's working more: (based in delta xd)

local hilbish = require 'hilbish'

local function branch ()
    local _, gitbranch = hilbish.run('git rev-parse --abbrev-ref HEAD', false)

    return gitbranch:gsub('\n', '')
end

print(branch())

but i don't really know how to remove that 1 (that changes to 0 when the command fails), do you know how can i remove it?

[AlphaTechnolog]

if i remove gitbranch:gsub('\n', ''), it hide the number, but when i remove it, it doesn't trim the last line space, but if i add it (the string.gsub), for some reason, it adds the 0 or the 1

[TorchedSammy]

gsub returns 2 arguments: the resulting string and the amount of matches just wrap the return in a () like return (str:gsub('h', 'ay')) and that will only take the 1st return value. in the context of where it is used in delta it only takes the 1st but i should maybe change it to be bug prone

but also: can i recommend promptua, it would actually be nice to get some more stuff added to that.
