A virtual terminal for parsing ANSI escape codes in python

I tried to use this package to parse data my script was receiving from a stream, but found that it could not handle partial escape sequences - once it sees that the input starts with an escape character, it expects the input to contain a complete escape sequence.
When I added buffering in the package to try to work around this, I found that the regular expression was treating partial sequences as complete sequences.
I suspect that using a regular expression means you cannot handle partial sequences, because a regular expression won't tell you if you have a partial match or not, and you need to know that to determine whether you're ever going to get a match given the current buffered input.
I eventually found that https://github.com/pexpect/pexpect provides an ANSI package which is similar to ansiterm but is able to handle being fed from a stream. I just wanted to mention this as it might be useful information for others. I haven't really done an in-depth comparison of the two packages [edit: but one limitation I've noticed is that pexpect's package doesn't properly parse, and doesn't store, attributes].
