pySerial-Terminal

A more capable(*), modular terminal (* than pySerial's miniterm)

Currently a work in progress.

Misc

There are some layers and indirections. The aim is to be able to implement different I/O devices without re-implementing the escape decoder logic each time.

console

  • read keys (return key names)
  • output operations using API (query/move cursor, erase parts)
  • backends: windows, [posix, GUIs]

terminal

  • escape_decoder: decode escape sequences and call methods on emulation object
  • providing constants

emulation

  • mapping escape_decoder calls to console
  • simple version decoding colors and movements, not supporting some of the features
  • [aiming for] nearly full VT220 (e.g. no printing support)
