Diff problems only with GUI but not in terminal

[fgarcia]

I got again an old known error while using :Gdiff

Error detected while processing function <SNR>61_Diff:
line   51:
E97: Cannot create diffs

The funny thing is that I get that error only while running the graphical version (MacVim) but not if I run that common from the terminal version.

Any ideas?

OK, this was a problem I had long ago and it took me 2 minutes to solve myself after opening the issue. I will leave it open if this can help others or make vim-fugitive more robust:

I solved the problem by searching only GUI config and found this:

if has('gui_running')
  set shellcmdflag=-ci
end

Removed that, everything is fine

Yeah, you'll note that E97 does mention shell config. I don't think -i is absolutely off limits but depending what's in your shell config it could easily break not just diffing but anything that shells out. You might hunt through your shell config to find the trigger.

Closing because I don't think that will inhibit others finding this issue.
