Ctags
From Wikipedia, the free encyclopedia
Ctags is a program that generates an index (or tag) file of objects found in source and header files of various programming languages. Each of these tags signifies an object of the language for which an index entry is available. These tags allow items to be quickly and easily located by a text editor or other utility. Alternatively, there is also an output mode that generates a cross reference file, listing information about various objects found in a set of language files in human-readable form.
The original Ctags was introduced in BSD Unix and was written by Ken Arnold, with Fortran support by Jim Kleckner and Pascal support by Bill Joy.
