RE: Skip includes in comment with checkpath option.

Hi Ben,

>>> I don't see how this avoids comment lines. I actually don't see how it
your include pattern at all.

Not comment line has to start at first column and it looks like this:
*Include, input=path
Comment line is when I put ** at the beginning, so it maybe be:
**Include, input=path
***Include, input=path
** *Include, input=path

It means I can get not comment include line for :checkpath command with:
\\c^\*include\\s*,\\s*input\\s*=
and comment and not comment include line for gf command with:
\\c\*include\\s*,\\s*input\\s*=

>>> but it won't match "include" without the * either.
You are right but it is not a problem for me since syntax "Include,
input=path" is incorrect and should never occur.

>>> You don't define a Checkpath! command, you define a Checkpath command
and handle the !
>>> :help :command-bang
>>> :help <bang>
Awesome! Now my function is:

command! -buffer -bang Checkpath :call <SID>Checkpath("<bang>")
function! s:Checkpath(bang)
let includeOld = &include
let &include = "\\c^\*include\\s*,\\s*input\\s*="
execute "checkpath" . a:bang
let &include = includeOld
endfunction

So :checkpath is looking for all includes and :Checkpath for not commented.
Perfect, that's all what I need.

Thanks!

Regards,
Bartosz

I modeled this regex after the default value. I did not expect this
modification to have *any* effect on the gf command. But now I see the
problem.

gf normally uses 'isfname' to find the file under the cursor. In your case,
the = and everything else in your include statement also are in 'isfname' so
your gf command will get the whole command.

According to :help 'include' you should be able to add \zs\f* to the end of
your pattern to match all filename characters AFTER the include syntax, and
use those for gf.

Was my explanation not clear? At a high level, this replaces "any
whitespace" with "anything not containing **".

The solution should be the same: append \zs\f*

I don't see how this avoids comment lines. I actually don't see how it your
include pattern at all. I interpret this as:

\c - case-insensitive search
* - match a literal '*' character
etc. as normal

And then this one matches only on lines that start with "*include". So I
suppose it won't match "**include" comments, but it won't match "include"
without the * either.

You don't define a Checkpath! command, you define a Checkpath command and
handle the !
