not showing white pieces

tested on google colab

Can you provide a link to Google Colab? I've never used the service before.

You can run the executable with --silent to hide the board at launch, then disable the colors with hide color and enable the board with show board.

steps

!apt install cargo
!cargo install littlewing
!cp /root/.cargo/bin/littlewing /bin/
!littlewing --silent

hide color
show board
move e4
time 1 10
show think
play black

root cause
seems hide color is the root cause

nice to have

• can parsing hide color as argument,
  or
  at least fix the white pieces not shown without execute hide color
• can parsing play white or black or both as argument, so user no need to type play black
• can parsing pgn file output
• can parsing log file (for detail execution, in case littlewing is used by another software e.g. scid, chessx, xboard, etc)

e.g.

littlewing -w human -b human -pgn ./test.pgn -log ./test.log
littlewing -w engine /bin/littlewing -b human -pgn ./test.pgn -log ./test.log
littlewing -w human -b engine /bin/littlewing -pgn ./test.pgn -log ./test.log
littlewing -w engine /bin/littlewing -b engine /bin/stockfish -pgn ./test.pgn -log ./test.log

The colors will be automatically disabled if the engine is not running from a tty. But the issue that you a reporting seems to come from Google Colab that is displaying a white foreground ANSI code on a white background.

Please note that the engine can also switch to XBoard or UCI protocol when used by another software.

I think what you are suggesting is already covered pretty nicely by cutechess-cli?
