SourceTree keep on chrashing with enabled daff in git project

[studentutu]

Good afternoon, it works perfectly as intended in standart git bash, but each time I'm trying to see the diff on the actual file inside the SourceTree it crashes. Could you make some kind of a workaround for it? I'm trying to fix it with myself, but to no avail(

Hi @studentutu, is that top window (the one with "Select a file to view the diff") vscode? Perhaps it is confused by custom diff formats (I'm surprised it crashes though). I'll take a look at installing vscode and replicating. Thanks for reporting the problem.

@paulfitz sorry for not giving more info about the issue - top window is just a SourceTree window, but yes, I'm using VSCode as my default viewer, though sourcetree has it's own view on the diffs

[studentutu]

@paulfitz HI, have you tried to reproduce the issue?

[paulfitz]

@studentutu I did install VSCode, and poked around, but I see now that was the wrong program. Is "SourceTree" this application? https://www.sourcetreeapp.com/

[studentutu]

@paulfitz yes, Sourcetree - better GUI for large projects if you are using Unity/Unreal game engine or similarly larged projects,sorry I should have posted it in the issue(

If it can help a way to avoid the problem for me was to remove the integration of daff into git and add the following to my .gitconfig

[alias]
    diff-csv = !git -c diff.external=\"daff diff --git\" diff *.csv

With that you can run git diff-csv when you want to see the diff of all the csv in your repository, but external tools like Sourcetree are not affected.

I have the same issue.
