Szathmáry László honlapja @ DEIK | Nim2 / Colors in the terminal #2

In a previous post we saw how to print colored texts manually. Now, let's see how to do it with the standard library.

import std/exitprocs

import std/terminal
addExitProc(resetAttributes) # just to be sure

proc main() =
styledEcho styleBright, "Hello, Bold!" # resets at the end
echo "normal text"
stdout.styledWriteLine fgBlue, styleBright, "Hello, Bold and Blue!"
stdout.styledWrite bgCyan, fgWhite, styleBright, "NimOS", resetStyle, "> " # no newline
echo "..."

when isMainModule:
main()

bold is called bright here

"Procs like styledEcho, styledWrite, styledWriteLine have a temporary effect on text parameters. Style parameters only affect the text parameter right after them. After being called, these procs will reset the default style of the terminal. While setBackGroundColor, setForeGroundColor etc. have a lasting influence on the terminal, you can use resetAttributes to reset the default style of the terminal."
