Jupyter QtConsole: select one of the built in CSSs as the default via configuration

问题

I am using Jupyter in Windows. I mean to change coloring of the QT console.

How can I select one of the built in CSSs as the default, via configuration file?

I mean to avoid passing it as an argument as in jupyter qtconsole --style monokai. I would rather use a configuration file, e.g. file1 = %USERPROFILE%\.jupyter\jupyter_qtconsole_config.py What I ultimately want to do is write monokai in some configuration file, and have the QTconsole load the built-in monokai.

What I tried so far:

1. As a test, execute jupyter qtconsole --style monokai. It actually brought monokai (white fgr on dark gray bgr). Moreover, it combined well with my selected c.ConsoleWidget.font_size = 12 in file1.

2. Then, trying to use my own css. I copied a monokai.css file in C:\Users\user1 (I have quite a few in my system, but I guess any one should work for the most basic stuff). In file1 I included one of the lines

   c.JupyterQtConsoleApp.stylesheet = u'C:/Users/user1/monokai.css'
   c.JupyterQtConsoleApp.stylesheet = 'C:/Users/user1/monokai.css'
   c.JupyterQtConsoleApp.stylesheet = 'C:\\Users\\user1\\monokai.css'
   

   None worked.

If I made this work, I would still have to find how to replace the specification of a file as a location by a simple CSS name among the built-in.

PS: I know I could also set a Windows shortcut that launches jupyter qtconsole --style monokai. I also mean to avoid this.

回答1:

This is a solution, but I am not certain it is the only one, or if it is the most portable across systems. Note: there might be some issues, yet to be solved, in the way this configuration works, see https://github.com/jupyter/qtconsole/issues/334

Use

c.JupyterWidget.syntax_style = 'monokai'

in file %USERPROFILE%\.jupyter\jupyter_qtconsole_config.py or ~\.jupyter\jupyter_qtconsole_config.py.

Inspired by this.
