function 在 vim 修复报价

Question

I'm trying to create a function in vim to be activated by a shortcut and go through my document and re-quote the strings using Python-like syntax. That is:

• "something" -> 'something'
• '''docstring''' -> """docstring"""
• "'" -> "'" (stays the same)
• '"' -> '"' (stays the same)

Given my limited knowledge of python functions I came up with this in my .vimrc :

function! Fixquotes()
   :silent! %s/"\([^"]*\)"/'\1'/g
   :silent! %s/'""/"""/
   :silent! %s/""'/"""/
   :silent! %s/'''/"""/g
endfunction

inoremap <C-f> <esc>mk:call Fixquotes()<CR>`kli
noremap <C-f> mk:call Fixquotes()<CR>`k

It kinda work, except for the case where I have "'" since the first substitution will turn it into ''' and the last will turn it into """ .

Does anyone have any recommendation?

Answer 1

give this a try:

function! Fixquotes()
   :silent! %s/\v([^'"]|\_^)\zs"([^"']*)"\ze([^'"]|\_$)/'\2'/g
   :silent! %s/'''/"""/g
endfunction
