NAME

       tags - Generate Emacs TAGS file from Erlang source files

DESCRIPTION

       A  TAGS file is used by Emacs to find function and variable definitions in any source file
       in large projects. This module can generate a TAGS  file  from  Erlang  source  files.  It
       recognises functions, records, and macro definitions.

EXPORTS

       file(File [, Options])

              Create a TAGS file for the file File.

       files(FileList [, Options])

              Create a TAGS file for the files in the list FileList.

       dir(Dir [, Options])

              Create a TAGS file for all files in directory Dir.

       dirs(DirList [, Options])

              Create a TAGS file for all files in any directory in DirList.

       subdir(Dir [, Options])

              Descend  recursively  down  the  directory  Dir and create a TAGS file based on all
              files found.

       subdirs(DirList [, Options])

              Descend recursively down all the directories in DirList  and  create  a  TAGS  file
              based on all files found.

       root([Options])

              Create a TAGS file covering all files in the Erlang distribution.

OPTIONS

       The functions above have an optional argument, Options. It is a list which can contain the
       following elements:

         * {outfile, NameOfTAGSFile} Create a TAGS file named NameOfTAGSFile.

         * {outdir, NameOfDirectory} Create a file named TAGS in the directory NameOfDirectory.

       The default behaviour is to create a file named TAGS in the current directory.

EXAMPLES

         * tags:root([{outfile, "root.TAGS"}]).

           This command will create a file named root.TAGS in the  current  directory.  The  file
           will contain references to all Erlang source files in the Erlang distribution.

         * tags:files(["foo.erl", "bar.erl", "baz.erl"], [{outdir, "../projectdir"}]).

           Here  we  create  file  named  TAGS placed it in the directory ../projectdir. The file
           contains information about the functions, records, and macro definitions of the  three
           files.
