In some languages I can put Esc codes around text to make them colored on Linux console/terminal. However, this does not seem to work in Rebol:
NORMAL: "\e[0m"
RED: "\e[0;31m"
print rejoin["\e[0;31m" "red text" "\e[0m"]
Above code only produces black (usual colored) text output:
\e[0;31mred text\e[0m
Can colored text output be printed with Rebol on Linux terminal?
You can similarly use colour codes in Rebol/Red.
print "This text is ^[[0;31mred^[[0m text."
#"^[" is the Escape character in Rebol/Red.
You can, for example, change the prompts in Red with the following codes:
system/console/prompt: "^[[31m^[[5D>>^[(B^[[m "
system/console/result: "^[[32m^[[5D==^[(B^[[m"
In the Ren-C branch of Rebol 3 you can change the prompts with the following (similar) codes:
system/console/prompt: "^[[31m^[[5D>>^[(B^[[m "
system/console/result: "^[[32m^[[5D==^[(B^[[m "
