过滤掉ANSI转义序列 [英] Filtering out ANSI escape sequences

问题描述

我有一个python脚本，该脚本试图解释分别向stdout和stdin写入和读取的数据痕迹。问题在于，这些数据充满了我不在乎的ANSI转义符。这些转义是JSON编码的，因此看起来像 \033 [A和 \033] 0;。我实际上不需要解释代码，但是我确实需要知道每个代码中包含多少个字符（您会注意到第一个序列是6个字符，而第二个序列是7个字符）。有没有直接的方法可以从我拥有的字符串中过滤掉这些代码？

I have a python script that's trying to interpret a trace of data written to and read from stdout and stdin, respectively. The problem is that this data is riddled with ANSI escapes I don't care about. These escapes are JSON encoded, so they look like "\033[A" and "\033]0;". I don't actually need to interpret the codes, but I do need to know how many characters are included in each (you'll notice the first sequence is 6 characters while the second is 7). Is there a straightforward way to filter out these codes from the strings I have?

推荐答案

控制序列的完整正则表达式（又名ANSI）转义序列）是

The complete regexp for Control Sequences (aka ANSI Escape Sequences) is

/(\x9B|\x1B\[)[0-?]*[ -\/]*[@-~]/

请参考 ECMA-48第5.4节和 ANSI转义代码
