how to exclude files when using globpath() function

I want to obtain in Vim any file in a path that doesn't have a .tex or .bib extension.

I tried (in order to ignore tex files) the following command

:echo globpath({some path}, '*.[^tex]*')

but that will also ignore combinations of tex characters (for instance .toc files).

So how can I modify the pattern in order to match any file without .tex or .bib extension?

Edit: Vim' negative lookahead is done with \@!. I have a directory /test with the files foo.bib, foo.tex, foo.pdf, foo.aux and foo.toc. I tried doing

:echo globpath('C:/Users/Pedro/Desktop/test', '\w*\.\%\(tex\|bib\)\@!')

but that returns an empty string.

Solution

to use globpath() function, you don't need regex. it's a glob function. you can just set the wig option (wildignore) , then call the function .

set wig=*.bib,*.tex

then

:echo globpath('/your/path','*.*')

do a test:

kent$  pwd
/tmp/test

kent$  ls -1
bar.bib
bib.bar
f.txt
tex.foo
x.tex

in vim:

:set wig=*.bib,*.tex
:echo globpath('/tmp/test','*')

we got:

/tmp/test/bib.bar
/tmp/test/f.txt
/tmp/test/tex.foo

note that you can call it globpath('/path','*',0,1) to have returned value in a list, sometimes it is handy to use in script.
