iPython - 更改双下划线（魔术）属性的颜色？

Question

I updated iPython to:

Python 3.6.7 (default, Mar 29 2019, 10:38:28) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.4.0 -- An enhanced Interactive Python. Type '?' for help.

What I noticed is that double underscore attribute likes __name__ have dark blue color. My terminal is black, so those attributes are ridiculously dark and hard to see (look at A.__name__ ):

Is there a way to modify colors on iPython?..

I found this question, but it seems with 7.4.0 iPython, given answers no longer work.

How do I customize text color in IPython?

Answer 1

Looking in your installation directory you will find a file called ipython_config.py . To install this file, simply use the following command:

ipython profile create

Otherwise find this file and copy it in your ~/.ipython/profile_default/ directory.

Before editing it, make a backup of this file with:

cp ~/.ipython/profile_default/ipython_config.py \   
   ~/.ipython/profile_default/ipython_config.py_backup

Open this file with your editor of choice, search for following setting and comment it out (delete the '#'):

#c.TerminalInteractiveShell.highlighting_style_overrides = {}

you must have next code there:

## Override highlighting format for specific tokens

from pygments.token import Name
c.TerminalInteractiveShell.highlighting_style_overrides = {
   Name.Variable:    "#FF00FF"
}

Answer 2

You can override the highlight color for any of the tokens defined in pygments - there's a list in the pymgents documentation . The token you want to change is Name.Function.Magic . To do that, add the following to your ipython_config.py file (mine is in ~/.ipython/profile_default ):

from pygments.token import Token

c.TerminalInteractiveShell.highlighting_style_overrides = {
        Token.Name.Function.Magic: '#FF00FF'
}

This will make magic functions highlight in magenta - your preferences may vary :)
