"""Create a TAGS file for Python programs, usable with GNU Emacs.

#
|

# Create a TAGS file for Python programs, usable with GNU Emacs (version 18).
|
||||
# Tagged are:
|
||||
# - functions (even inside other defs or classes)
|
||||
# - classes
|
||||
# Warns about files it cannot open.
|
||||
# No warnings about duplicate tags.
|

The output TAGS file is usable with Emacs version 18, 19, 20.

||||
Tagged are:
|
||||
- functions (even inside other defs or classes)
|
||||
- classes

for file in args:
|
||||
treat_file(file, outfp)
|
||||
eptags warns about files it cannot open.
|

eptags will not give warnings about duplicate tags.

expr = '^[ \t]*\(def\|class\)[ \t]+\([a-zA-Z0-9_]+\)[ \t]*[:(]'

|
||||
BUGS:
|
||||
Because of tag duplication (methods with the same name in different
|
||||
classes), TAGS files are not very useful for most object-oriented
|
||||
python projects.
