Raxol.Terminal.ANSI.ExtendedSequences (Raxol v2.0.1)

View Source

Handles extended ANSI sequences and provides improved integration with the screen buffer. Functional Programming Version - All try/catch blocks replaced with with statements.

This module adds support for:

  • Extended SGR attributes (90-97, 100-107)
  • True color support (24-bit RGB)
  • Unicode handling
  • Terminal state management
  • Improved cursor control
