Very high CPU usage when piping

[widogg]

Hi! First time user, I just found this (pretty cool) tool and started using it right away.

I noticed a high CPU usage, which I think might be related to #17.

I'm using dpkg.log here as an example, but happen with other files too. When I do tl /var/log/dpkg.log, I have very low CPU usage and I can see the app normally, like this

However, if I do cat /var/log/dpkg.log | tl, I get a very VERY high cpu usage

Sorry the command is not fully displayed, but it definetly running tl here.

Also, I have to double ctrl+c to exit, which throws this error

I have the same problem, double ctrl+c to exit, and the terminal will display inputs of my mouse, like this

I found add line sys.exit() in this function can fix this problem(exclude high cpu usage). I am a beginner of python, not really sure if this is the right modification.

I have this problem.

$ tl --version
tl, version 1.4.0
$ echo '{"foo": "bar"}' > /tmp/log.json
$ cat  /tmp/log.json |tl

Uses 100% CPU on both Mac or Linux.
