警告:此答案仅与 兼容,IPython
5.5.0
并且似乎不能很好地与IPython
6+
. (感谢@meowsqueak 进行快速测试!)
从 开始IPython 5.5.0
,您可以覆盖任何样式颜色,这要归功于ipython_config.py
目标配置文件文件夹中的 。(即:~/.ipython/profile_default
用于default
linux 典型安装的配置文件)。
IPython 代码与着色相关的代码相当混乱,解析器、调试器和交互式 shell 使用了几种方法。一些部分使用Pygments
,另一些提供仅限于 16 色调色板的 ANSI 转义码。
该解决方案并不漂亮,但有效。如果还有其他更漂亮的方式,请在评论中告诉我!
请注意,由于扩展了默认调色板,我的解决方案还包括为 IPython 着色的每个部分使用 256 种或更多颜色的能力。下面的代码中有一个如何扩展到 256 色的示例。
所以这里是如何做的,列出所有可能使用的令牌:
