Using substitute command or global cmd to analyse a whole file

[epanda]

Hi,


I have done a func that I call on that way :

:%s/myPattern/\=MY_FUNC(submatch(4),submatch(5),submatch(3),submatch
(2))/



I would like to not substitute the pattern, just analyse each line.
Thanks



NB : I don't want to use while to read the file.

How about this?

:%call MY_FUNC(getline('.'))

HTH,

Add the n flag: :%s/.../.../n

That was my first thought too, but it looks like the replacement
portion isn't evaluated if you use the /n flag. I tried the
following on some sample text:

:let x=[] | %s/\w\+/\=add(x, submatch(0))/gn

and x was still empty at the end of it (it was populated when the
/n flag wasn't used). This suggests that Epanda's MY_FUNC()
won't get called with the /n flag. To get evaluation, I had to
do something like

:%s/myPattern/\=MyFunc(...)/g | u

to let it do the replacements and then undo them. This does
require an appropriate (non-zero) 'undolevels' setting.

Ahh ... now that you point it out, it's a bit obvious that
evaluating the replacement should be pointless when using 'n'.

add \zs at the end of the search pattern and let your function return
an empty string:

function! MY_FUNC(a, b, c, d)
" ...
return ''
endfunction

:%s/myPattern\zs/\=MY_FUNC(submatch(4),submatch(5),submatch(3),submatch(2))/

Thanks, I didn't remind zs but effectively it is the solution I
wanted.

I was using u (undo) temporary.

Thank to all of you

I think, this should work:
Define your function such that you pass submatch(0). Inside your
function you can then access all different submatches. At the end of
your function return submatch(0).
