A bug has been introduced with the work done here and it relates to the tokenization of ansi escape characters. We noticed it with ansiEscapes.link and I added a test case in this repo which now fails.

@AlCalzone I don't know enough about your ansi-tokenize project, but could this be fixed there?

Here's a screenshot of the failing test:

You can see from the screenshot that the link escape is not being closed properly so the link "leaks" in all the text after that.

I agree this needs to be fixed in ansi-tokenize

Fixed in v0.1.3: https://github.com/AlCalzone/ansi-tokenize/releases/tag/v0.1.3

(except that your test has extra " around the string)

@AlCalzone thank you for fixing this so quickly! I've bumped the version in this PR.

@AlCalzone we also saw a difference in the ansi escapes related to colors when upgrading. For example this component

<Box>
  <Text color="red">hello</Text>
  <Text color="green">world</Text>
</Box>

Before it would produce

'�[31mhello�[39m�[32mworld�[39m'

Now it produces

'�[31mhello�[32mworld�[39m'

There seems to be a missing [39m after the first word which I think it's the code to reset the color? Not sure if this is a difference in the way chalk works, maybe it has been updated? The end result doesn't seem to change much in our outputs.

That's expected. ansi-tokenize uses the least amount of ansi codes necessary for a style change.

Got it! Make sense, I'll update our tests.
