No Option to Compare
I am running Obsidian v1.1.16 on Windows and have installed this plugin. Thanks for writing it.
However, when I open my command palette and search for file diff the only option I see is File Diff: Find sync conflicts and merge. I do not see an option for just File Diff: Compare.

Any ideas?
You need to have a file open in order to access the other two options. Basically, when you have a file open, it will serve as the base file and you'll be asked to select a comparison file.
Another user also struggled with this issue. So it's worth considering making this more user friendly. I could make the other two options always available and if no file is open the user is prompted twice, for the base file and for the comparison file.
For now I think it's alright, but I'm always happy to hear suggestions for improvement. If the issue receives 10 likes, I'd be more than willing to make the change.
Great, thanks for the reply.
Thanks for your detailed answer @friebetill. It works
UPDATE (SOLVED): I had a look at the Console, and every single keystroke was causing errors with the plugin 'make.md'. Incidentally, I was also having issues with the Outline panel not being able to find any headers at all.
Updated the plugin, and now both are working again. Always update your plugins, I guess ðĪŠ
Not currently using that particular plugin, so think I'll just disable it.
âââââââââ I'm having exactly the same issue, except it's not getting solved by having a note open.
No matter which note I open, CMD+P (macOS) -> 'diff' only shows "find sync conflicts and merge" (also true when I type 'file diff' or 'merge'). This is with the cursor active in the note.
I've also tried setting a hotkey for "File Diff: Compare and merge", but nothing happens when triggered.

For me it's mainly about improving the documentation ;) I wasn't able to find "compare" too.
Just write some lines in your readme about 1) having the file open, 2) having the cursor in the file and then 3) open command dialogue, 4) choose compare (&merge) and 5) select second file. Would have shortened my research ...
Anyway, thanks for the great extension.
