|
||
|
|
|
||

// colorize a string, SLOW
|
||
|
|
msg := ansi.Color("foo", "red+b:white")
|
||
|
|
|
||
|
|
// create a FAST closure function to avoid computation of ANSI code
|
||
|
|
phosphorize := ansi.ColorFunc("green+h:black")
|
||
|
|
msg = phosphorize("Bring back the 80s!")
|
||
|
|
msg2 := phospohorize("Look, I'm a CRT!")
|
||
|
|
|
||
|
|
// cache escape codes and build strings manually
|
||
|
|
lime := ansi.ColorCode("green+h:black")
|
||
|
|
reset := ansi.ColorCode("reset")
|
||
