Anton,

See if this suits your purpose: http://cheeseshop.python.org/pypi/SE/2.2%20beta
Below the dotted line is how it works.

# 1. List your ansi codes and invent concise place holders. Define each one like this 'symbol=ansi_escape'.
>>> ansi_escapes = '''
   ::=(x1b)[0m       # Cancel all previous escapes
   :B:=(x1b)[1m     # bold
   :blue:=(x1b)[34m
   # etc.
'''

# 2. Mark your text up with your symbols
marked_up_text = "this has some :B:bold:: text and some :blue:blue:: text and some :B::blue:text that is bold and blue::"

# 3 Make an SE Stream Editor.
>>> import SE
>>> Ansiizer = SE.SE (ansi_escapes)

# 4. Stream-Edit
>>> ansiized_text = Ansiizer (marked_up_text)
>>> ansiized_text
'this has some \x1b[1mbold\x1b[0mtext and some \x1b[34mblue\x1b[0m text and some \x1b[1m\x1b[34mtext that is bold and blue\x1b[0m'

----------------------------------------------------------------------------------------------------------

# Alternatively you may first write your definitions into a file. You then make your ansiizing Stream-Editor simply by naming the
file, say 'your_path/ansi_definitions.se'.

>>> Ansiizer = SE.SE ('your_path/ansi_definitions.se')

----------------------------------------------------------------------------------------------------------

# You can do files directly

>>> Ansiizer ('some_path/text_file', 'some_path/text_file_ansiized')
