Infixed constants that return ANSI escape sequences
ANSI Constants is a Murex convention of passing ANSI escape sequences into strings. It uses the {}
notation with the constant name placed in between two curly braces. eg {GREEN}
.
Rather than duplicate the constants from source, and risk the documentation and implementation drifting, this document will embed the source directly below.

Each line will look something a little like
"GREEN": {27, 91, 51, 50, 109},
The part within quotes is the constant name, and the part that follows is the sequence of bytes that are infixed.
So the example above will replace {GREEN}
from within a string with the byte values of 27, 91, 51, 50 and 109 (in that order).
If a constant does not exist in the above code, then the infix string is left unedited.
# Green spelt correctly
» out "{GREEN}PASSED{RESET}"
PASSED
# Green spelt incorrectly (ie so that it doesn't exist as a valid constant)
» out "{GREEEEN}PASSED{RESET}"
{GREEEEN}PASSED
These sequences are enabled by default. To disable run the following:
» config set shell color false
You will need to add this to your Murex profile, ~/.murex_profile
to make it persistent.
