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"}]). .br .br .br 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. .br .br

*

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