CodeMirror的“模式”可以用颜色替换标签吗？

Question

I want to display an ansi document (Unix terminal transcripts with escape codes to apply colors) in CodeMirror , but there is no mode for that.

I could try to make my own mode, and although it seems quite complicated, I haven't found any mode to use as a template that actually removes certain characters from the original content.

I need to remove the escape characters and use them to mark the start or end of a color.

Is this at all possible? Or does CodeMirror by design lack the possibility to do this (remove characters in a mode )?

Any other ideas?

Answer 1

This is possible, but awkward. A mode won't do this (as you noticed, it doesn't remove characters -- you could style them display: none , but that'll cause other problems.

An addon that listens for "change" events and uses markText 1 to style and hide pieces of the document could work. But making it clever (only updating the parts that change, rather than re-coloring the whole document on every change) requires some complexity.
