GNU teseq 1.1 released

Item posted by Micah Cowan <micahcowan> on Tue 11 Jun 2013 10:37:45 PM UTC.

Announcing the release of version 1.1 of GNU Teseq, the Escape Sequence
Illuminator. This is the first new release in 5 years, since the 1.0
release in 2008.

GNU Teseq is a tool for analyzing files that contain control characters
and terminal control sequences, by printing these control sequences and
their meanings in readable English. It is intended to be useful for
debugging terminal emulators, and programs that make heavy use of
terminal features such as cursor movement, coloring, and other effects.

Version 1.1

  • Colorized output now supported via the --color (or --colour) option, and the TESEQ_COLORS environment variable.
  • Descriptions and labels for non-standard controls from DEC, Xterm, Rxvt, etc, are now always issued, without the need for the -x option.
  • Reseq now recognizes "halt" (@@@) lines (with --halts option), waiting for keypress before continuing.
  • Teseq now identifies which charset is being switched, by its ISO IR registration.
  • BUG FIX: Teseq could crash on the input, `\033$z'.

Building GNU Teseq

Building Teseq requires nothing beyond a normal Unix build
environment, though running the full suite of accompanying tests, or
building documentation, requires some additional software.
