Skip version check

[casimir]

I am trying to use universal-ctags, which is more or less exuberant-ctags maintained, so it should be completely compatible. The problem is that easytags considers this version incompatible. This come from the fact that universal-ctags isn't versioned, its version is always "Development".

% ctags --version
Universal Ctags Development, Copyright (C) 1996-2009 Darren Hiebert

Do I understand correctly that universal-ctags is a fork of Exuberant Ctags >= 5.8? In that case it should be fully compatible indeed (until they start making backwards incompatible changes ;-) so I can see if I can get the version check to accept "Universal Ctags Development".

[casimir]

I was actually waiting for a response from you before investigate more. :angel: I switched to it like 1 week ago and except for your plugin I didn't encounter any problem. I saw in there doc that they are merging exuberant patches so I would say they are backward compatible. They have a specific section for this in there doc: https://github.com/universal-ctags/ctags/blob/master/docs/tracking.rst#exuberant-ctags

I just published vim-easytags version 3.11 where I've tried to at least make the version check accept Universal Ctags as an alternative to Exuberant Ctags. I don't have time to try Universal Ctags at the moment, so I can't confirm if this is enough to get things going. Can you give it a try and report back? Thanks for the feedback!

[casimir]

After a few hours with several languages (c, go, rust, python) still no problem. Thanks a lot. :smile:

Hi, I'm a developer of universal ctags. Could you look at https://github.com/universal-ctags/ctags/issues/748 ?

These days I'm planing releasing 1.0.0. As the first step I changed the output of ctags --version. Now universal ctags has following output:

% ./ctags --version
./ctags --version
Universal Ctags 0.0.0(93f3c66), Copyright (C) 2015 Universal Ctags Team
Universal Ctags is derived from Exuberant Ctags.

I have found a fix is available: https://github.com/Wraul/vim-easytags/commit/f5746bdfd9942b00c349e53f3f4917ae73bb6797 !

As @masatake has reported, there is a supposed fix available, but it is a pull request from December 24, 2015 that has neither been accepted or rejected. https://github.com/xolox/vim-easytags/pull/133

@xolox I'm still seeing the following. Is that intended?

% vim .
easytags.vim 3.11: Plug-in not loaded because Exuberant Ctags 5.5 or newer is required while you have version 0.0.0 installed!
Press ENTER or type command to continue

% which ctags
/usr/local/bin/ctags

@xolox whoops -- I completely overlooked the date on the your earlier comment, sorry D: disregard my last

[bew]

@xolox Any possible news on this ? (see @jkrmr message above) I'm currently using https://github.com/Wraul/vim-easytags/commit/f5746bdfd9942b00c349e53f3f4917ae73bb6797 which works correctly

[jmromer]

@Bew78LesellB I ended up using the following as a workaround, if it's helpful at all:

" suppress ctags version warning (since universal-ctags)
let g:easytags_suppress_ctags_warning = 1

[talmobi]

@xolox @jkrmr That gets rid of the warning but sadly fails to run the plugin (:UpdateTags not available etc) and therefore fails to run cats automatically. Running ctags manually (ctags -R) works fine.

Using the latest universal-ctags version:

Universal Ctags 0.0.0(0d8de20), Copyright (C) 2015 Universal Ctags Team

Running with exuberant-ctags gives me warnings and fails to work at all (doesn't even work manually):

$ ctags --version

All I can find on tags of any kind are pretty old comments (this thread being the latest almost a year old) -- perhaps there's a mother similar solution people are using these days?

[masatake]

(I don't use vim, so what I write here may be pointless.)

If you have a trouble in output format of ctags, consider to use --output-format=e-ctags.

These days --output-format option is added to handle a tag including whitespaces. The default format (u-ctags) includes the tag. The classic format (e-uctags) excludes the tag.

Following example shows the difference.

[jet@localhost]% cat /tmp/foo.html 
cat /tmp/foo.html 
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
  <head>
  </head>
  <body>
    <h1>abc</h1>
    <h1>e f g </h1>    
  </body>
</html>
[jet@localhost]% ~/var/ctags/ctags --output-format=e-ctags -o - /tmp/foo.html
~/var/ctags/ctags --output-format=e-ctags -o - /tmp/foo.html
abc /tmp/foo.html   /^    <h1>abc<\/h1>$/;" h
[jet@localhost]% ~/var/ctags/ctags  -o - /tmp/foo.html
~/var/ctags/ctags  -o - /tmp/foo.html
abc /tmp/foo.html   /^    <h1>abc<\/h1>$/;" h
e f g   /tmp/foo.html   /^    <h1>e f g <\/h1>    $/;"  h

For anyone else stumbling upon here I ended up following the vim plugin tagbar wiki (which is up to date) of using jsctags (and tern which it depends on) and universal-ctags for everything else (CSS etc) -- works great (you don't have to use the vim tag bar plugin but I found that the plugin actually works quite nicely so will probably use it).
