TermNG (Next Generation)

• Senses 24bit colour (truecolor) when $TERM_COLOR=16m environment variable is set.
• Adds --color=16m to front of process.argv before wrapping the supports-color module.
• Indicate enhanced media support by setting:
  • $TERM_IMAGES=enabled : Allow rendering of inline images using OSC sequences.
  • $TERM_AUDIO=enabled : Allow enhanced audio.
• Indicate that you use a font that has box drawing or full extended characters.
  • $TERM_FONT=box : Terminal font has UTF8 box drawing characters.
  • $TERM_FONT=full : Terminal font has full UTF8 extras (such as Menlo, DejaVu Mono).
• Sense $TERM suffixes to indicate enhanced termcap capabilities.

In fish, it's a simple as defining a universal, exported variable.

  set -Ux TERM_IMAGES enabled
  set -Ux TERM_FONT full

In bash an export TERM_IMAGES=enabled in ~/.bashrc will do the trick. I don't use tcsh or zsh anymore so can't remember exactly which files are used when those shells are invoked interactively. Fish is almost always invoked interactively - which is kind of the point of fish, it being the 'Friendly INTERACTIVE Shell' after all! Write scripts for portablility (sh/bash/perl even node) then write fish functions to interact with those scripts from the keyboard... but I digress.

Usage

Terminal Color Test

From inside the package directory, running npm run-script colors will generate a preview of the entire color gamut your terminal is capable of. Output of a recent iTerm shown below:
