notes on vim

Vim is a text editor. My slowly-evolving configuration can be found on GitHub, in bpb-kit.

Tyler Cipriani is a lot smarter than I am about vim (and, in fact, most things), but I am particular and don’t always share his preferences.

keybindings

I’m starting in on this notebook, which uses a Makefile, and think it might be nice to have a quick vim keybinding for :make. I would use F5, by analogy to QBasic, but I’ve already bound that to :wall, which writes all the open buffers with changes.

I think that maybe <leader>m, which in my case means ,m, would be ok. Then I’m not sure if something is already mapped starting with that, so I try :map.

I want to search through the list produced by :map, and think it’d be nice if I could just read it into a buffer. The first thing I google is “vim read output of command into file”. This could easily enough give hits for reading the output of a shell command, but the 3rd thing down the page is Capture ex command output on the Vim Tips Wiki.

There are a bunch of interesting ideas there, but the first basic idea is this:

:redir @a
:set all
:redir END

Then you can open a new buffer - :new - and do "ap. This says “using the named register a, paste”.

This seems to work with :set all, but not so much with :map. Why not? I skim :help map and help redir without getting very far. Updates to come.

With that digression still unanswered, the mapping I settled on is simple:

nmap <leader>m :make<CR>

I never know if these are going to take with me. The handful of custom bindings that have actually entered my vocabulary are super-useful, but more often than not I wind up forgetting about an idea not long after I’ve implemented it.
