Vim::Tag - Generate perl tags for vim


version 1.110690


    $ ptags --use ~/code/coderepos -o ~/.ptags

In .vimrc:

    set tags+=~/.ptags

then this works in vim:

    :ta Foo::Bar
    :ta my_subroutine

bash completion:

    cpanm Bash::Completion::Plugins::VimTag
    alias vit='vi -t'

then you can do:

    $ vit Foo::Bar
    $ vit my_subroutine

Custom tag generation

    package Foo::Bar;

    $::PTAGS && $::PTAGS->add_tag($tag, $filename, $line);


Manage tags for perl code in vim, with ideas on integrating tags with the bash programmable completion project. See the synopsis.

You should subclass this class to use it in your ptags-generating application. It could be as simple as that:

    #!/usr/bin/env perl
    use warnings;
    use strict;
    use base qw(Vim::Tag);

And if you want just that, there's the ptags program. But it is more interesting to extend this with custom aliases and to have your modules generate custom tags and so on. The documentation on those features is a bit sparse at the moment, but take a look in this distribution's examples/ directory.



Takes a tag name, a filename and a 'search' argument that can either be a line number which caused the tag, or a vim search pattern which will jump to the tag. It will add the tag to the tags hash.


Adds tags to find a class' superclass, generated if --use is in effect.


Adds tags for YAML::Marshall serialization handlers.


Takes a pattern and deletes all tags that match this pattern. It's not used directly in this class or in ptags, but if you write a custom tags generator you might want to munge the results.


Determines which directories should be searched. This includes all of @INC and anything set via --libs. We also weed out nested directories. For example, @INC might contain


Then we don't want the first one, but we do want the second one.

We go through library directories in @INC order. I assume that custom directories will be unshift()-tacked onto @INC so they come first - this happens with use lib, for example. That means that the main perl libraries will come last. By going through the libraries in reverse order, a local version of a module will take precedence over a module that's installed system-wide. This is useful if you have a module both under development in your $PROJROOT as well as installed system-wide; in this case you most likely want tags to point to the locally installed version.


Finalizes things just before the tags are written. Here we just very specifically avoid END{} processing when Test::Base has been loaded.


Goes through all files in the directories set in determine_libs() and calls process_pm_file() for .pm files or process_pod_file() for .pod files. The directories bin, t, blib and inc (used by Module::Install) are pruned.


Makes a tag for a given package.


Takes a list of regex/replace pairs and applies each pair to each tag name. If the name has been changed by the s/// operation, a new tag is recorded.

It's not used directly in this class or in ptags, but if you write a custom tags generator you might want to munge the results. For example, you might want to make alias tags for long package names. Instead of My::Very::Long::Package::Namespace::* you might like to have mvlpn::* tags.


Processes the given .pm file.


Processes the given .pod file.


The main method that calls the other methods to do its work. This is the method your tag generator - for example, ptags - will call.


If you use --use and the packages load modules which can't be loaded easily in the context of Vim::Tag or which have some side-effects, you can act as though that module has already been loaded.

This method takes a list of package names and changes @INC for each one.

It's not used directly in this class or in ptags, but if you write a custom tags generator you might need to use it.


Writes the generated tags to the file determined by --out in a format vim can understand.


  • ptags only has one global tags file and generates everything every time it is run. This is especially a problem if you have various perl installations, for example, using perlbrew: Every time you switch between perl installations you'd have to re-run ptags to keep it up-to-date.
