export selected commit as diff/patch

[Stricken1670]

The current fastest workflow is to hit y and then copy the hash to the clipboard and then run: git format-patch -1 7ae304975444ab0632affb1eceab0399ee3971d4 --stdout > diff.diff

Which works but is still rather clunky.

Simply exporting the diff to a file would be awesome.

Sounds like an ideal candidate for a custom command.

You can also hit y and then d to copy the diff, and then something like pbpaste >diff.diff. (Replace pbpaste with whatever works for your platform.)

But I agree with the custom command suggestion. Here's mine (I use these to copy commits between repos):

customCommands:
  - key: X
    description: "Commits"
    commandMenu:
      - key: c
        command: 'git format-patch --stdout {{.SelectedCommitRange.From}}^..{{.SelectedCommitRange.To}} | pbcopy'
        context: commits, subCommits
        description: "Copy selected commits to clipboard"
      - key: v
        command: 'pbpaste | git am'
        context: "commits"
        description: "Paste selected commits from clipboard"

I'm not sure we need to add more than this to lazygit. Exporting the diff to a file would require that we add some sort of file picker to lazygit, which I don't think is justified for this feature. You are probably faster doing this in your shell where you have tab completion for selecting folders etc.
