Hi,
I'd like to use pygments to colorize source file data displayed in a Text
widget.
To do so, I set a palette with names from pygments tokens. Here is a simple
example::
--- 8< ---- Begin (test.py) ---- 8< ----
#! /usr/bin/env python
import urwid
from pygments import lex, lexers, token
class Foo(object):
'''Just to get a class'''
def __str__(self):
'''return this python source code as a string'''
fid = open(__file__)
python_code = fid.read()
fid.close()
return python_code
def highlight_code(text):
"""return formated text using pygments"""
return list(lex(text, lexers.PythonLexer()))
PALETTE = [(token.Token.Text, 'default', 'default'),
(token.Token.Name, 'dark blue', 'default'),
(token.Token.Name.Function, 'light blue', 'default'),
(token.Token.Comment, 'dark gray', 'default'),
(token.Token.Literal.String, 'yellow', 'default'),
]
text = highlight_code(str(Foo()))
widget = urwid.Filler(urwid.Text(text))
screen = urwid.raw_display.Screen()
mainloop = urwid.MainLoop(widget, PALETTE, screen)
mainloop.run()
--- 8< ---- End (test.py) ---- 8< ----
Running ``python test.py`` displays a highlighted source code. But it is not
exactly what as I expect.
For example, *Foo* is not highlighted because pygments sets the "style" to
*token.Token.Name.Class*. But I'd like that *Foo* is in "dark blue" because
*token.Token.Name.Class* is a "sub-style" of *token.Token.Name* (instead of
defining all "sub-style of "token.Token.Name" to the same style).
>From now urwid stores the palette in a dictionary (ex: raw_display.py line 51
changeset d6d6ae081dcf of https://excess.org/hg/urwid/).
Is it possible to add a way to tune the palette container for a dict-like class
that suite special needs?
Bests,
Alain
