does it support wsl?

I threw together a quick single-threaded rust implementation of this, and found a ~5.21x performance improvement compared to the multi-threaded implementation of BLAHAJ.

This performance improvement still carries over to larger inputs:

For abnormally large files that you usually wouldn't pass through this (32768 lines in the 1st below example, 12MB of #\n repeating in the 2nd), the gap does get significantly smaller, however there is still a significant performance improvement:


Also, my testing does not include a multithreaded rust implementation, which could be even faster. I'm guessing the lower gap in the last 2 is primarily due to my implementation being singlethreaded.

As a result of this discovery, I thought it might be worth mentioning that rewriting this in rust may provide a significant performance advantage overall :)

Note that my implementation is very barebones, and a more complete implementation may see less of a performance improvement - however it should still see some of the 1.3x to 5x improvement.

If the stdin is not a pipe, we are not coloring the output of any commands, instead we are coloring our inputs in the terminal. This looks boring and is not expected.

We have several ways to detect if stdin is a pipe or a terminal. isatty(STDIN_FILENO) can detect terminal and S_ISFIFO(st.st_mode) can detect pipe. I don't know any clue about crystal though.

It would be cool if a new release could be published, since a new flag has been added!

it seems like only the trans flag works. image:
