Thorsten BallandBennet 69e698c3be terminal: Fix blinking settings & blinking with custom shape (#18538)
This is a follow-up to #18530 thanks to this comment here:
https://github.com/zed-industries/zed/pull/18530#issuecomment-2382870564

In short: it fixes the `blinking` setting and the `cursor_shape` setting
as it relates to blinking.

Turns out our `blinking` setting was always the wrong value when using
`terminal_controlled` and the terminal _would_ control the blinking.

Example script to test with:

```bash
echo -e "0 normal \x1b[\x30 q"; sleep 2
echo -e "1 blink block \x1b[\x31 q"; sleep 2
echo -e "2 solid block \x1b[\x32 q"; sleep 2
echo -e "3 blink under \x1b[\x33 q"; sleep 2
echo -e "4 solid under \x1b[\x34 q"; sleep 2
echo -e "5 blink vert \x1b[\x35 q"; sleep 2
echo -e "6 solid vert \x1b[\x36 q"; sleep 2
echo -e "0 normal \x1b[\x30 q"; sleep 2

echo -e "color \x1b]12;#00ff00\x1b\\"; sleep 2
echo -e "reset \x1b]112\x1b\\ \x1b[\x30 q"
```

Before the changes in here, this script would set the cursor shape and
the blinking, but the blinking boolean would always be wrong.

This change here makes sure that it works consistently:

- `terminal.cursor_shape` only controls the *default* shape of the
terminal, not the blinking.
- `terminal.blinking = on` means that it's *always* blinking, regardless
of what terminal programs want
- `terminal.blinking = off` means that it's *never* blinking, regardless
of what terminal programs want
- `terminal.blinking = terminal_controlled (default)` means that it's
blinking depending on what terminal programs want. when a terminal
program resets the cursor to default, it sets it back to
`terminal.cursor_shape` if that is set.

Release Notes:

- Fixed the behavior of `{"terminal": {"blinking":
"[on|off|terminal_controlled]"}` to work correctly and to work correctly
when custom `cursor_shape` is set.
- `terminal.cursor_shape` only controls the *default* shape of the
terminal, not the blinking.
- `terminal.blinking = on` means that it's *always* blinking, regardless
of what terminal programs want
- `terminal.blinking = off` means that it's *never* blinking, regardless
of what terminal programs want
- `terminal.blinking = terminal_controlled (default)` means that it's
blinking depending on what terminal programs want. when a terminal
program resets the cursor to default, it sets it back to
`terminal.cursor_shape` if that is set.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
