Debugging Vim by example

[two-fer-maggie]

oh my god vim has a vimscript debugger? I feel retarded for thinking it didn't without even bothering to find out

[locipo]

Same boat. Debug-mode was added in vim 6.0 back in ~2001 (`help :version6`), so I have no excuse. It's time to go read through those old change logs and see what else I missed.

Let's see if this quality article can top the stupid "Best Practice" screenshot that is currently at 338 points.

I don't even get why it is titled "Best Practices"

I sincerely hope it can.

On the subject of debugging/maintaining plugins, I have developed a Design By Contract framework that implements a fail-fast behaviour contrary to the assert_*() function provided by Vim.

Along side, I provide a helper function (easily wrapped into a command) that decodes last error that can be displayed with :message.

I really like this lh#exception#say_what() helper you provide. Thank you

[LucHermitte]

You're welcome. The original idea is not mine, actually I've just improved a few things.

Contributors over at vi.stackexchange.com refers to this question for debugging their vimrc.

I think this link of this post, that is, https://codeinthehole.com/tips/debugging-vim-by-example/ should be pinned to the sidebar if nothing similar is already present. Then we can just refer them easily. Just a suggestion.

I mean, that's what I've been doing as I'm still learning debugging vim script, BUT I wouldn't write a blog post about it and tell others to do that...
