Tagbar is a vim plugin for browsing the tags of source code files. It provides 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.

Important: If the file structure is displayed 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 a bug. Since Tagbar uses exuberant-ctags and compatible programs to do the actual file parsing, it is likely that the bug is actually in one of those programs 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!
