Feature Request: :checkhealth check for duplicate mappings

[apppppppple]

I have my mappings separated into different files by plugin and right now if I overwrite one mapping with a different one it can be hard to tell that I did. I'd like to have a config option to enable checks for overriding mappings. If this is a feature you're okay with I'd be willing to do a pr for it.

I actually added a checkhealth today that does some checks already. I can easily add in a dup check as well.

[folke]

But feel free to add a PR for this. Thanks!

On second thought it might be better if you add it (if you're willing to and it's not too much work). I can't find where I should add it and I'm worried that I'd introduce a bug or some inconsistency.

[folke]

Added!

Hey thanks for adding health check! I'm getting this error while running it:

(For some reason in my setup I wasn't able to copy text to clipboard so I had to upload an image instead.)

[apppppppple]

Added!

Thanks a bunch! Sorry I chickened out

Looks like I'm having the same error as zlksnk but on the upside, it only happens when there are duplicates so it still somewhat works

[folke]

Sorry about that. Fixed that nil error. It means you have a duplicate global mapping :)

Ran checkhealth with latest which-key @folke and I'm getting a similar error, this time it received a string instead of nil. @apppppppple can you confirm?

[apppppppple]

just checked and yep I'm getting the exact same thing

[folke]

My bad, but just fixed it. Think I need some sleep 😅

It will show a message about buf=0, which is actually a global mapping.

[folke]

Still need to document what is being shown in healthcheck:

• conflicting means a mapping existed for something where WK would normally create a trigger, but we didn't (in most cases not an issue)
• overriding: this is because a mapping was registered that will override an existing one, which we did
• local buffer keymaps overriding global ones are probably on purpose, so this will be a warning (should be ok)
• keymaps overrriding other keymaps in the same buffer or global are probably not intended, so this will show as an error (probably not ok)

My bad, but just fixed it. Think I need some sleep sweat_smile

Works perfectly now thanks!
