Vim#

Notes about my editor of choice.

Sphinx ftplugin#

I am very proud of my first vim plugin: sphinx.vim

For now, only creating and changing headings is mapped on the F1-F6 keys.

Normally the following snippet would suffice:

fun! Vimfun()
    python pyfun()
endfun

But if you want to pass parameters, you’ll need something like this (please correct me if I’m wrong).

fun! Vimfun(x)
	python import vim
	python f(vim.eval(str('a:x')))
endfun

python << EOF
def f(x):
	print x
EOF

" run it
call Vimfun('Hello!')

To show all whitespace at line end:

:match Error /\s\+$/

To remove it:

:%s/\s\+$//

See also: :help usr_28. Set folding for XML (in .vimrc):

" XML syntax folding
let g:xml_syntax_folding=1
au FileType xml setlocal foldmethod=syntax

Shortcuts (from nion’s blog on 2009-03-23):

zf	create folder
zd	delete folder under cursor
zD	delete folder recursive
zE	delete all folders in file
zo	open folder under curso
zO	open folder recursive
zc	close folder under cursor
zC	same as zc recursive
za	open folder if closed, close folder if opened

w !some_command

NERDTree is the answer. Wanted it on the right, so I added a one-liner to my .vimrc:

let g:NERDTreeWinPos="right"

Beautiful.

It’s so easy, that it it is useful for even three lines in the same document. Suppose you are editing the following README file:

# entry 1
some text here
# entry 2
more text here
# entry 3
more text here

You want to change the format from entry 1 to Entry(id=1). Here’s what I did:

navigate cursor to “entry”, then hit * (all highlighted, because of 'hlsearch'.)
cwEntry(<ESC>n.n. does the first part of the substitution, but we are missing the closing brackets
record qq$a)<ESC>nq
- record q to register q (simple to type, also valid would be qx to record to register x)
- go to end of line, append the bracket, go back to normal mode and jump to next occurence $a)<ESC>n
- end recording q
and play @q@@
- apply macro in register q @q
- repeat last macro @@

To yank a word to register a type "ayw.

Show all registers with :reg and the register a with :reg a.

Paste register a in command mode (:) by hitting Control-r a. https://vi.stackexchange.com/a/15038
