python 使用占位符值替换指定的十六进制颜色值的所有出现。

Posted 2021-05-09

1. Preperation: Put color values in a file. One hex value per line. Case does not matter. (See old_color_example.txt for an example.)
2. Execute script python3 hex_replace.py /path/to/old_color_example.txt /path/to/YourColorScheme.thTheme
3. Result: A copy of your .tmTheme file will be generated with all the respective hex values replaced.

Modification of placeholder:
You can simply state a custom placeholder value as a third command line argument. Like so:
python3 hex_replace.py /path/to/old_color_example.txt /path/to/YourColorScheme.thTheme CUSTOM_PLACEHOLDER
