etags(1) General Commands Manual etags(1)
NAME
etags - Generates a tags file for the emacs or mule editor
SYNOPSIS
etags [-a | -append] [-C | -c++] [-D | -no-defines] [-i tagsfile2 | -include=tagsfile2] [-o tagsfile | -output=tagsfile] [-S |
-ignore-indentation] [-H | -help] [-V | -version] filename...
OPTIONS
Appends output to an existing vi-format tags file. (Supports operation of the emacs editor in vi mode.) Treats files with or extensions as
C++, rather than C, code. The etags command always treats files with extensions as C++ code. Does not create tag entries for C preproces-
sor definitions. If many header files are tagged, using this option may make the tags file much smaller. Includes a note in the output
tags file to indicate that, when searching for a tag, one should also consult the tagsfile2 tags file. Explicitly names the output tags
file; overrides the default name, which is TAGS. Instructs etags not to rely on indentation to determine nesting level. Currently, this
means not to assume that a closing brace in the first column is the final brace in a function or structure definition in C or C++ code.
Prints usage information. Prints the current version of the program.
OPERANDS
Specifies the input language source file, or files, to be processed.
DESCRIPTION
The etags program creates a tag table file in a format understood by the emacs editor. The program understands the syntax of C, C++, For-
tran, Pascal, and Lisp source files. It reads the source files specified on the command line and writes a tag table (named TAGS by default)
in the working directory. Recognition of the language used in an input file is based on the filename extension and file contents; there are
no options for specifying the language.
NOTES
The etags program is software distributed by the Free Software Foundation.
