You can always add one or more lines of comments above or below the
line including the pattern in a Vim script, or even, in most cases, at
the end of the line; but IIUC you cannot insert comments in the middle
of a pattern.
Ok. There is no solution so i decided to write functions that returns RE
chunks in vimfiles/autoload/RE{,/XML}.vim
2 advantages to proceed like this :
- readable.
- reusable
For Exemple, the way to match an XML tag is almost a FAQ on this list.
Why not provide something like the awsome Regexp::Common perl module ?
I wrote :
function RE#Magic()
return '\v'
endfunction
function RE#Submatch( regExp )
return '('.a:regExp.')'
endfunction
function RE#OptionnalSubmatch( regExp )
return '(%('.a:regExp.'){0,1})'
endfunction
function RE#XML#Ident()
return '[[:alpha:]][[:alnum:]]*'
endfunction
function RE#XML#NSIdent()
let ident = RE#XML#Ident()
" a namespace
" : separator
" a tagname
return
\ RE#OptionnalSubmatch( ident ) .
\ RE#OptionnalSubmatch( ':' ) .
\ RE#OptionnalSubmatch( ident ) .
endfunction
Comments and advices about it would be really nice.
To use perl regexps, you can of course embed perl statements in a
perl-enabled version of Vim; but of course at the cost of making the
script less portable.
I gave this solution away a long time ago. I think that all alien
langages (langages other than viml) is the worst idea of the vim
developper team.
