Columnizing a list with ANSI-color codes?
问题
Using column 或 pr -T3 列化带有 ANSI 转义的输入会导致项目的对齐出现问题，它们可能会过度或不足对齐。例如：ls -1 --color=always | column。
我正在编写一个文件管理器，想要实现两列的格式，就像 Midnight Commander 中的样式一样。好消息是，该项目是用 Zsh 脚本编写的，我希望有一种良好的方法来将颜色化的 fd ./exa -1 --color=always/ls -1 --color=always 输出进行列化，包括一个 Bash/Zsh/Awk 等脚本作为解决方案。是否有办法？
英文:
Using column or pr -T3 to columnize an input with ANSI escapes results in bad align of the items – they are under or overaligned. For example: ls -1 --color=always|column.
I'm writing a file manager and would want 2 columns format, like in Midnight Commander. The good part is that the project is written in Zsh script and I would want a nice way of columnizing color fd ./exa -1 --color=always/ls -1 --color=always output, including a Bash/Zsh/Awk/etc. script as a solution. Is there a way?

zsh内置的print命令似乎可以处理颜色，当使用-C和-c选项创建列时。源代码中甚至有这样的注释：
通过跳过转义序列来防止由于它们导致的列对齐不正确。八进制\033和\233是ANSI识别的可能转义字符。
将命令输出转换为print命令的参数可能有点棘手，但使用$(...)的命令替代和${(f)...}的行扩展应该可以工作：
print -C 2 ${(f)"$(ls -1 --color=always)"}
您还可以通过coprocess传递数据。
英文:
It looks like the zsh builtin print can handle colors when creating columns with the -C and -c options. The source code even has this note:
> * Prevent misaligned columns due to escape sequences by

> * possible escape characters recognized by ANSI.
Converting the command output to arguments for print can be slightly tricky, but this combination of a command substitution with $(...) and an expansion split by line using ${(f)...} should work:
print -C 2 ${(f)"$(ls -1 --color=always)"}
You also can pass in data via a coprocess.
