2009, amazing.

which I did, and it works.

This also helps, even if it spits out lines like:

ctags: Warning: ignoring null tag in includes/jquery/js/jquery.min.js

With Universal Ctags,

ctags -R .

throws out lines like

ctags: Warning: ignoring null tag in includes/jquery/plugins/flot/jquery.flot.pie.min.js(line: 7)

(but less than with Exuberant Ctags)

but works (no E431 error).

Don't know what are those "null tags" though.

Changing from Exuberant to Universal is a solution, thanks a lot.

I can now continue my learnings.

Have a nice day

Steve
