termion

• Drop Redox-specific code, now that it supports all libc functions

• Add helpers to get terminal size from file descriptor

• Remove debug printing when parsing CSI sequences
• Support NO_COLOR environment variable

• Remove debug printing when parsing CSI sequences

• Support NO_COLOR environment variable

Remove unused code and update dependencies.

Fixes an error check in Ctrl-Arrow code, no difference in behavior. Cleaned up examples.

Fixes a regression in function keys F5 and above.

4.0.0 adds support for horizontal scrolling when working with MouseTerminal.

3.0.0 to 4.0.0 guide

A change is only necessary if you were matching on all variants of the MouseEvent enum without a wildcard. In this case, you need to either handle the two new variants, MouseLeft and MouseRight, or add a wildcard.

v3 release improves raw terminal API and enables support of any TTY target.

2.0.0 to 3.0.0 guide

Changes are only required if you were using IntoRawMode on generic terminals W: Write. Now, terminal is also required to implement AsFd trait. So replacing generic bounds with W: Write + AsFd should be sufficient.

Termion 1.0.0 is out! This release is breaking, which is also the reason for the semver bump.

Highlights

Lot'ta goodies.

• Mouse support: If you enabled mouse mode through the MouseTerminal struct, you can get mouse events (thanks to IGI-111).
• TrueColor support: You can now use true color, by the Rgb struct.
• A complete revision of the way escapes are handled: Everything is now done through Display instead of custom traits.
• isatty wrapper: termion::is_tty takes any T: AsRawFd and gives you a bool.
• Crates.io release: Previously, it was distributed solely through git. This turns out to be very convinient, but quite critical whenever making breaking changes (that is, major semver bumps).
