Tagbar: a class outline viewer for Vim
What Tagbar is
Tagbar is a Vim plugin that provides an easy way to browse the tags of the current file and get an overview of its structure. It does this by creating a sidebar that displays the ctags-generated tags of the current file, ordered by their scope. This means that for example methods in C++ are displayed under the class they are defined in.
What Tagbar is not
Tagbar is not a general-purpose tool for managing
tags files. It only
creates the tags it needs on-the-fly in-memory without creating any files.
tags file management is provided by other plugins, like for example
A ctags implementation: We highly recommend any version of Universal Ctags. It is a maintained fork of Exuberant Ctags with many bugfixes, support for many more formats, and proper Unicode support.
Exuberant Ctags 5.5 or higher works to some degree but will be deprecated eventually.
Extract the archive or clone the repository into a directory in your
'runtimepath', or use a plugin manager of your choice like
pathogen. Don't forget to run
:helptags if your plugin manager doesn't do it for you so you can access the
If the ctags executable is not installed in one of the directories in your
$PATH environment variable you have to set the
variable, see the documentation for more info.
Put something like the following into your ~/.vimrc:
nmap <F8> :TagbarToggle<CR>
If you do this the F8 key will toggle the Tagbar window. You can of course use
any shortcut you want. For more flexible ways to open and close the window
(and the rest of the functionality) see the documentation using
Support for additional filetypes
For filetypes that are not supported by Exuberant Ctags check out the wiki to see whether other projects offer support for them and how to use them. Please add any other projects/configurations that you find or create yourself so that others can benefit from them, too.
Note: If the file structure display is wrong
If you notice that there are some errors in the way your file's structure is displayed in Tagbar, please make sure that the bug is actually in Tagbar before you report an issue. Since Tagbar uses exuberant-ctags and compatible programs to do the actual file parsing, it is likely that the bug is actually in the program responsible for that filetype instead.
There is an example in
:h tagbar-issues about how to run ctags manually so
you can determine where the bug actually is. If the bug is actually in ctags,
please report it on their website instead, as there is nothing I can do about
it in Tagbar. Thank you!
You can also have a look at ctags bugs that have previously been filed against Tagbar.
