Trice Channels and Color

Trice is usable without channels and color similar to printf also.

1. How to get

  • Add a channel name as color descriptor in front of each TRICE format string like "wrn:Peng!".
  • In file ../internal/emitter/lineTransformerANSI.go the colors are changeable and additional color channels definable.
  • It is possible to concatenate single colorized letters to get output like this:

./ref/COLOR_output.PNG

  • ../pkg/src/triceCheck.c contains the code for this example.
  • The trice tool, if knowing wrn: as pattern, prepends the appropriate color code. It removes the sequence wrn:, if it is known and completely lower case.
  • The user can define any pattern with any color code to create colored output with the trice tool.
  • There is no channel enable switch inside the target code. It would need a back channel and add overhead.
    • A future extension could make that an option using channel specific ID range assignment. See also here and issue #243.
  • The trice tool offers the 2 command line switches -pick and -ban to control channel visualization during runtime.

2. Color issues under Windows

Currently console colors are not enabled by default in Win10, so if you see no color but escape sequences on your powershell or cmd window, please refer to Windows console with ANSI colors handling or simply use a Linux like terminal under windows, like git-bash. One option is also to install Microsoft Windows Terminal (Preview) from inside the Microsoft store and to start the trice tool inside there. Unfortunately this can not be done automatically right now because of missing command line switches. Alacritty is one of other alternatives.
