Question

I\'m trying NERDtree which is pretty cool, but what I\'d like to do is execute special commands, or scripts, on the selected file.

For example, I\'d like to highligh

After research I found a solution that seems to do exactly what I wanted. This piece of code shoud be inserted in a file under ~/.vim/nerdtree_plugin (or equivalent directory under other operating systems):

call NERDTreeAddKeyMap({
    \ 'key': 'b',
    \ 'callback': 'NERDTreeInsertImage',
    \ 'quickhelpText': 'Insert XHTML tag of image' })

function! NERDTreeInsertImage()
    let n = g:NERDTreeFileNode.GetSelected()
    if n != {}
        let @i = system("~/perl/image.pl " . n.path.str())
        normal ^Wp"ip
    endif
endfunction

it adds a mapping to key b which runs the function NERDTreeInsertImage() which takes the full path of the selected file in the browser and passes it as an argument to my perl script. Of course ^W is inserted as .

Hope this can be helpful to some other Vim user :)

@romainl this is the very simple Perl script (requires ImageMagick module):

#!/usr/bin/perl

use strict;
use warnings;
use Image::Magick;

my $source = $ARGV[0];

my $img = Image::Magick->new;

$img->Read($source);

my ( $width, $height ) = $img->Get('width', 'height');
print qq##;
