Some vim (or iTerm2?) ANSI sequences not fully consumed about ansi-regex

[shyndman]

I believe I've verified it is iTerm2's doing, not vim's.

Running this in my shell:

echo '\x1b[0;38;5;121mwidth\x1b[0m:\x1b[0;103m100%\x1b[0m;'

Gives me this back when copied:

�[0;38:5:121mwidth�[0m:�[0;111m100%�[0m;

I'm curious to hear what you think.

Correct me if I'm wrong but this has nothing to do with the ansi-regex node.js package.

[shyndman]

Well, it might? Like I said, I'm not an expert. Is that valid ANSI or not? The regex doesn't match on it.

Is it or isn't it the purpose of this package to match on ANSI escape codes?

It's just that you didn't provide any code to indicate you're even using this library.

> s ='\x1b[0;38;5;121mwidth\x1b[0m:\x1b[0;103m100%\x1b[0m;'
'\x1B[0;38;5;121mwidth\x1B[0m:\x1B[0;103m100%\x1B[0m;'
> r = new RegExp(pattern, 'g')
/[\u001B\u009B][[\]()#;?]*(?:(?:(?:(?:;[-a-zA-Z\d\/#&.:=?%@~_]+)*|[a-zA-Z\d]+(?:;[-a-zA-Z\d\/#&.:=?%@~_]*)*)?\u0007)|(?:(?:\d{1,4}(?:;\d{0,4})*)?[\dA-PR-TZcf-nq-uy=><~]))/g
> r.exec(s)
[
  '\x1B[0;38;5;121m',
  index: 0,
  input: '\x1B[0;38;5;121mwidth\x1B[0m:\x1B[0;103m100%\x1B[0m;',
  groups: undefined
]
> r.exec(s)
[
  '\x1B[0m',
  index: 18,
  input: '\x1B[0;38;5;121mwidth\x1B[0m:\x1B[0;103m100%\x1B[0m;',
  groups: undefined
]
> r.exec(s)
[
  '\x1B[0;103m',
  index: 23,
  input: '\x1B[0;38;5;121mwidth\x1B[0m:\x1B[0;103m100%\x1B[0m;',
  groups: undefined
]
> r.exec(s)
[
  '\x1B[0m',
  index: 35,
  input: '\x1B[0;38;5;121mwidth\x1B[0m:\x1B[0;103m100%\x1B[0m;',
  groups: undefined
]
> r.exec(s)
null

Seems like it works fine.

Can you show some code?
