### MODULE

tags

### MODULE SUMMARY

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.
