The remover discards terminal control sequences, including CSI commands and OSC hyperlink destinations.

Ordinary text and hyperlink labels remain. Tabs, carriage returns, line feeds, backspace, and NUL also remain.

  • Remove colour commands from captured compiler output before comparing two build logs.
