[Feature Request] Support any external tool

[bla-bu]

Hi,

I'm using SourceGit for Linux "under" WSL, version 2025.08. I wanted to configure some additional external tool that I could launch from within SourceGit. I created external_editors.json:

 {
    "tools": {
        "Visual Studio Code": "/usr/local/bin/code",
        "Notepad++": "/usr/local/bin/npp"
    }
}

And whereas "Visual Studio Code" is available and working nicely, npp is not added to the menu. Would be possible to extend this feature so that:

• any tool can be added
• icon for the tool can be configured
  ?

Thank you,

• First, the external_editors.json is used for portable-app that supported by SourceGit. If you have a recommendation for another text editor, you can create a PR or name its official website.
• Second, I'm Chinese. I'll never add Notepad++ in this repo. If you want, you can fork this project, and make your own modifications in your repo.

BTW, you can use Custom Action to open this repo with an external editor.

Additional, SourceGit supports use editors defined in git settings, so you can config in git like this (vscode as example):

[diff]
    tool = vscode-diff
[difftool]
    prompt = false
[difftool "vscode-diff"]
    cmd = code --wait --diff $LOCAL $REMOTE
[merge]
    tool = vscode-merge
[mergetool "vscode-merge"]
    cmd = code --wait $MERGED

Edit: Sorry for misunderstand the request.

Hi, Thanks for quick answer. Firstly, npp was just an example (it seems it brings some tension). However, what I'm looking for is a customizable list of tools that I can run with "Open with...", independently of the selected repo. This way I could add any tool without the need of forking the entire repo. Also, these don't have to be editors, e.g. another tool I would like to add is dnGrep.

Thanks again,

As shown in my configuration above, a custom diff/merge tool requires at least two different commands to be configured, and there shouldn't be many git GUI tools that provide such a configuration. Using git's own configuration is relatively simple.
Edit: Sorry for misunderstand the request.

For dnGrep:

• First, create a new Custom Action
  
• Second, run this action

If you want to configure dnGrep in CUSTOM ACTION, you must download the latest CI build from Github Action.

Commit e65cb50 fixes the issue that some external tool do not support path with / as delimitter

Thanks. This works (at least for opening repositories) but I still have a small issue. I have 74 repositories under my Code dir, I'm not working on all of them all the time, but still, configuring the Custom Action for every single repository will be painful. Do you think you could introduce "Global Custom Actions" e.g. something taken from preference.json and automatically populated to all repositories?

[love-linger]

Done. You can download the latest CI build from Github Action.

You are quick :-) Works, thank you!
