Research on Terminals

All tested with their latest version obtainable of Arch Linux (or macOS 11, Windows 10) as of writing. Version tested is noted where possible, but otherwise compare to the git blame date.

To contribute entries:

  • Insert in the correct category, in lexicographic order
  • Test with both the terminal’s own terminfo, and with xterm-256color.
  • If the terminal doesn’t have its own terminfo, note that, and note which it is trying to emulate.
    • And consider filing a bug to tell them to provide their own terminfo!
  • If a terminal has forks, especially if there’s a lot of them, only document a fork if its behaviour is different.
  • If the terminal is based on a common library, mention it.
  • If the terminal is web-based, mention that.
  • Document the current selection of ::default().
  • Document the behaviour of at least:
    • Terminfo
    • TerminfoScreen
    • TerminfoScrollback
    • VtRis
    • XtermClear
  • “Normal” behaviour refers to:
    • ::default(): screen and scrollback (if at all possible) cleared
    • Terminfo: at least screen cleared, and optionally scrollback
    • TerminfoScreen: only screen cleared
    • TerminfoScrollback: only scrollback cleared
    • VtRis: screen and scrollback cleared, and (at least some modes of) terminal reset
    • XtermClear: screen and scrollback cleared
    • Cls: screen and scrollback cleared
    • WindowsVtClear: screen and scrollback cleared
  • There is zero tolerance for advertising via this document.

How to test:

First link the clscli example program into your PATH, e.g.

ln -s $(pwd)/target/debug/examples/clscli ~/.local/share/bin/clscli

Open the terminal in its default profile, or as it comes when first installed.

Then use env | grep TERM to see what the TERM and other related variables look like (make note!).

Look into /usr/share/terminfo for a terminfo that matches the terminal, or wherever it is on your system. If there's a separate but official package for the terminal’s terminfo, use it.

First test with the native terminfo: set it either in the terminal’s settings, or use env TERM=name $SHELL, then with the TERM the terminal first starts with by default, and finally with xterm-256color if that’s not been covered yet.

  1. First run clscli auto. Look quick, the name of the variant selected by default will be printed, and one second later, hopefully, the screen will clear. Document that variant.
  2. Then run clscli Variant where the variant is: Terminfo, TerminfoScreen, TerminfoScrollback, VtRis, XtermClear, and the variant discovered in 1, if not one of these. Before each, run seq 1 100 or something like it to fill the screen and some scrollback. Document the behaviour if it differs from normal, or state “normal.”
  3. Optionally (if you want), if clscli auto does not exhibit the normal behaviour, open an issue and provide enough details to be able to modify the ::default() selection to select a different default that works. If you’re really enthusiastic, you can even open a PR with it!
  4. To submit your research, either submit a PR to this file (preferred, you can even do it in the GitHub Web UI), or open an issue with your research (I’ll merge it in), or send me an email.

Platforms

On macOS, the terminfo for xterm and variants does not by default include E3, which makes Terminfo not clear scrollback and TerminfoScrollback return an error (E3 not found), even when the terminal in question actually does support E3. For that reason, default behaviour on macOS is switched to use XtermClear if the TERM starts with xterm and the terminfo doesn’t have E3.

If the terminfo database is not available, ::default() falls back to XTermClear instead of supplying a useless Terminfo. When testing, it's expected to have a functional terminfo where practical.

  • TerminfoScrollback: does not clear scrollback, erases the screen, but leaves cursor position intact, i.e. at the bottom of the screen if we were there.
  • VtRis: clears screen, doesn’t clear scrollback, but does push the existing output up, so that information is not lost.
  • XtermClear: as for Terminfo.
