Syntax coloring of operators, brackets, parentheses etc.

Spyder Version: 2.2.4
Python Version: 2.7.4
Qt Version : 4.8.4, PyQt4 (API v2) 4.10 on Linux
pyflakes >=0.5.0: 0.6.1 (OK)
pep8 >=0.6 : 1.3.3 (OK)
IPython >=0.13 : 0.13.2 (OK)
rope >=0.9.2 : 0.9.2 (OK)
sphinx >=0.6.6 : 1.1.3 (OK)
matplotlib >=1.0: 1.2.1 (OK)
sympy >=0.7.0 : None (NOK)
pylint >=0.25 : 0.26.0 (OK)

It would be highly preferrable to be able to specify syntax coloring for operators and brackets as well, since they are some of the most important parts of the code.

With operators, I mean characters like +, -, %, =, etc.

Brackets: (), {}, [] etc.

(For example, I ususally want to have them in some red color, to more easily see the structure of the code.)

Well, "," and "." are also important operators.

That's a good idea ! But don't forget ":" too. And ";", even if it shouldn't be used much.

Colouring operators wouldmake the code much more readable. Is there any update on this issue?

[ccordoba12]

Only if you work on it :-)

[Zoodinger]

I did actually look into it a bit, I decided to give it a shot. If you can give me any information that can save me some time it will be appreciated :)

Question @andfoy: is this something the pysyintect takes care of?

Otherwise I think we could close this issue.

[ccordoba12]

VSCode uses semantic highlighting too and it only colors operators (not braces).

So I think we can close this one as a duplicate of #1500.

While waiting for this feature to be integrated into Spyder,
I managed to highlight the punctuation in my Spyder (6.1.3) on my setup.
Here's how to do it.

First, in your spyder.ini file (mine is located at
C:\Users<me>.spyder-py3\config).

To color punctuation red, add:

spyder/punctuation = ('#ff0000', False, False)
<your theme>/punctuation = ('#ff0000', False, False)

My theme is Spyder Dark. So in my .ini file, I added:

spyder/dark/punctuation = ('#ff0000', False, False)

Then edit the file syntaxhighlighters.py, located at
...\Spyder\envs\spyder-runtime\Lib\site-packages\spyder\utils\

In the COLOR_SCHEME_KEYS dictionary, add at the end:

    "punctuation": _("Punctuation:")

In COLOR_SCHEME_DEFAULT_VALUES, add at the end:

    "punctuation":("#ff0000", False, False)

In the make_python_patterns function, just before the return statement, add:

    punctuation_list = [
        r'\(', r'\)', r'\[', r'\]', r'\{', r'\}', ':', '=',
        '<', '>', r'\.', ',', '%', r'\+'
    ]
    punctuation = any("punctuation", punctuation_list)

And in the return statement, just before any("SYNC", [r"\n"]), add:
punctuation,

Thanks for chiming in @rochemelon. We'll try to include your suggestions in our 6.2.0 version, to be released during the second half of the year.
