Minimal-Terminal / Supported Escape Sequences

Standard escape codes are prefixed with Escape:

  • Ctrl-Key: ^[

  • Octal: \033

  • Unicode: \u001b

  • Hexadecimal: \x1B

  • Decimal: 27

  • CSI - Control Sequence Introducer: sequence starting with ESC [ or CSI (\x9B)

Followed by the command, somtimes delimited by opening square bracket ([), known as a Control Sequence Introducer (CSI), optionally followed by arguments and the command itself.

Arguments are delimeted by semi colon (;).

For example:

\x1b[1;31m  # Set style to bold, red foreground.
  • Any whitespaces between sequences and arguments should be ignored. They are present for improved readability.
