Truncate git branch name

[SunMar]

Hi,

While I was setting up I ran into the problem that my git branch names are too long. They can sometimes be up to 50 characters long which takes up a lot of space. It would be nice if it's possible to set a maximum (f.ex. 20 or 30 characters) and truncate anything after that.

Sorry, took a bit for me to add back the git segment in my prompt. Thank you very much to take the time to add this feature @JanDeDobbeleer!

Unfortunately the new branch_max_length doesn't seem to be working for me. Possibly I'm doing something wrong?

mkdir omp_test
cd omp_test/
git init
git config user.email test@ohmyposh.dev
git config user.name omp
git commit --allow-empty -m test
git branch some-very-long-branch-name-that-is-going-to-take-up-65-characters
git checkout some-very-long-branch-name-that-is-going-to-take-up-65-characters

My git segment is configured like this:

{
    "type": "git",
    "style": "powerline",
    "powerline_symbol": "\ue0b0",
    "foreground": "#d4e157",
    "background": "#546e7a",
    "properties": {
        "display_status": true,
        "branch_max_length": "25"
    }
}

Here is my full theme file:

@SunMar I take it you upgraded oh-my-posh and restarted your terminal

ooh wait, it's an int so you need to change it to "branch_max_length": 25

[SunMar]

@JanDeDobbeleer yes in the screenshot you can see that I'm on the latest version 3.166.0 from yesterday and indeed I did restart the terminal just to be sure. Oh My Posh doesn't use a background service like powerline can, does it? I assumed I don't have to kill anything or reboot, just restart the terminal session.

Oops, sorry about the int, not sure why I put it between quotes. But changing that doesn't seem to resolve the issue, I'm still seeing the whole branch name when I expected to only see a partial some-very-long-branch-nam.

My updated theme is:

{
    "type": "git",
    "style": "powerline",
    "powerline_symbol": "\ue0b0",
    "foreground": "#d4e157",
    "background": "#546e7a",
    "properties": {
        "display_status": true,
        "branch_max_length": 25
    }
}

Just to be sure I double checked PowerShell as well using the same theme file (with the int fix), and there it's also not truncating:

[JanDeDobbeleer]

@SunMar allow me to validate this. Maybe I missed something obvious. Can you in the meantime ensure git is up-to-date as well?

[SunMar]

@JanDeDobbeleer Thank for taking the time to check.

My WSL is running Ubuntu 21.04 and has git version 2.30.2 installed, which is the latest version available in the Ubuntu repositories.

In Windows my git version is the latest 2.32.0 and in PowerShell my posh-git version is the latest 1.0.0.

Let me know if there is any else I can help with.

[JanDeDobbeleer]

@SunMar fix incoming. Json parses as float. Standard "unit test succeeds, integration test fails" scenario.

[SunMar]

@JanDeDobbeleer it's working now, thank you very much !! 🥳
