This refactors the snippet logic to be largely unaware of the rest of
the document. The completion application logic is moved into
generate_transaction_from_snippet which is extended to support
dynamically computing replacement text.
When accepting a snippet completion we automatically delete the
placeholders for now as doing so manual is quite cumbersome. In the
future we should keep these as a mark + virtual text that is
automatically removed once the cursor moves there.
Parser-combinators are one of the simpler tools for building ad-hoc
parsers. They're a good fit because they are...
* Small: each parser / parser-combinator is around 10 LOC.
* Functional: helix_core strives to be a functional set of utilities
usable throughout the rest of the editor.
* Flexible: use them to build any sort of ad-hoc parser. In the child
commit, we'll parse LSP Snippet syntax using these new parser
combinators.
Why not use an existing parser-combinator crate? Existing popular
parser-combinator crates have histories of making breaking changes
(for example nom and combine).

Tree-sitter has some unreleased improvements that can speed up small
queries and prevent hangs due to error recovery in some parsers. This
change pins tree-sitter to the latest master.
Neovim also pins tree-sitter to a commit on master.

Add a restart debug session command, which would issue a
[Restart Request][1], if the debugger supports it and a session is
running. It uses the same arguments and requests used to start the
initial session, when recreating it.
It builds upon #5532, making use of the changes to the termination
workflow of a session.

This fixes breakage when installing `helix` due to an incorrect usage of
`as_ref()` when interacting with `bstr` in the `gitoxide` codebase.
However, this upgrade also requires a higher rustc version, as `gitoxide`
recently updated its `windows` crate version.
Using the picker with syntax highlighting the
fallback `ui.selection` makes a lot of text,
especially for the light variant, hard to read.
Instead, use a lighter background for highlights
This is a workaround for a freeze when suspending Helix with C-z on
non-Windows systems. The check for the keyboard enhancement protocol
locks up crossterm's internal event reading/polling system by trying to
set up multiple concurrent readers. `input_stream.next()` sets up one
reader looking for regular crossterm events while the
`supports_keyboard_enhancement` query sets up another looking for
internal events. The latter hangs for two seconds or until the former
yields an event. By handling signals first we don't lock up the mutex
by trying to read keyboard events.
Fixes a regression introduced in #5420 where a scrolloff of `x - 1`
was used instead if `x` at the bottom of the screen. This was
especially problematic if the scrolloff was set to `0` in that case
the scrolloff behaved as tough set to `-1` and the cursor disappeared
from the view if scrolled to the botoom.
Since crossterm 0.26.x, we receive press/release keyboard events on
Windows always. We can ignore the release events though to emulate
the behavior of keyboard input on Windows on crossterm 0.25.x.
When the Kitty Keyboard Protocol is enabled, S-backspace is
distinguished from backspace with no modifiers. This is awkward when
typing because it's very easy to accidentally hold shift and press
backspace temporarily when typing capital letters.
Kakoune (which is also a Kitty Keyboard Protocol application) treats
S-backspace as backspace too:
