The clipboard special registers are able to retain multiple selections
and also join the value when copying it to the clipboard. So by default
we should yank regularly to the '*' and '+' registers. That will have
the same behavior for the clipboards but will allow pasting multiple
selections if the clipboard doesn't change between yanks.
Since the clipboard provider now lives on the Registers type, we want
to eliminate it from the Editor. We can do that and clean up the
commands that interact with the clipboard by calling regular yank,
paste and replace impls on the clipboard special registers.
Eventually the clipboard commands could be removed once macro keybinding
is supported.
This fixes a discrepancy between regular registers which are used for
yanking multiple values (for example via `"ay`) and regular registers
that store a history of values (for example `"a*`).
Previously, the preview shown in `select_register`'s infobox would show
the oldest value in history. It's intuitive and useful to see the most
recent value pushed to the history though.
We cannot simply switch the preview line from `values.first()`
to `values.last()`: that would fix the preview for registers
used for history but break the preview for registers used to yank
multiple values. We could push to the beginning of the values with
`Registers::push` but this is wasteful from a performance perspective.
Instead we can have `Registers::read` return an iterator that
returns elements in the reverse order and reverse the values in
`Register::write`. This effectively means that `push` adds elements to
the beginning of the register's values. For the sake of the preview, we
can switch to `values.last()` and that is then correct for both usage-
styles. This also needs a change to call-sites that read the latest
history value to switch from `last` to `first`.
This is an unfortunately noisy change: we need to update virtually all
callsites that access the registers. For reads this means passing in the
Editor and for writes this means handling potential failure when we
can't write to a clipboard register.
These special registers join and copy the values to the clipboards with
'*' corresponding to the system clipboard and '+' to the primary as
they are in Vim. This also uses the trick from PR6889 to save the values
in the register and re-use them without joining into one value when
pasting a value which was yanked and not changed.
These registers are not implemented in Kakoune but Kakoune also does
not have a built-in clipboard integration.

This register also comes from Kakoune. It's read-only and produces the
current document's name, defaulting to the scratch buffer name
constant.

These come from Kakoune:
* '#' is the selection index register. It's read-only and produces the
selection index numbers, 1-indexed.
* '.' is the selection contents register. It is also read-only and
mirrors the contents of the current selections when read.
We switch the iterators returned from Selection's `fragments` and
`slices` methods to ExactSizeIterators because:
* The selection contents register can simply return the fragments
iterator.
* ExactSizeIterator is already implemented for iterators over Vecs, so
it's essentially free.
* The `len` method can be useful on its own.
This sets up a new Registers type that will allow us to expand support
for special registers. (See the child commits.)
We start simple with the regular (`Vec<String>`) registers and the
simplest special register, the black hole. In the child commits we
will expand these match arms with more special registers.
The upcoming special registers will need a few things that aren't
possible with the current Registers type in helix-core:
* Access to the `Editor`. This is only necessary when reading from
registers, so the `&Editor` parameter is only added to
`Registers::read`.
* Returning owned values. Registers in helix-core returns references
to the values backed by the `Vec<String>` but future special registers
will need to return owned values. We refactor the return value of the
read operations to give `Cow<str>`s and iterators over those.
* Returning a `Result` for write/push functions. This will be used by
the clipboard special registers.
* fix vlang grammar fetch and build fail
* update highlights.scm for v-analyzer
* Update languages.toml

This resolves a build issue with nci/dream2nix and git dependencies.
We can keep most of the helix-specific parts of the flake, we just need
to switch from configuring nci to calling craneLib functions.
We also switch to flake-utils from flake-parts:
* Using rust-overlay with flake-parts directly is unergonomic
(see https://github.com/hercules-ci/flake-parts/discussions/83).
* Removing flake-parts reduces the overall dependencies: rust-overlay
already depends on flake-utils.
This removes a handful of allocations for functions calling into the
function, which is nice because the prompt may call this function on
every keypress.
Pascal and I discussed this and we think it's generally better to
take a 'RopeSlice' rather than a '&Rope'. The code block rendering
function in the markdown component module is a good example for how
this can be useful: we can remove an allocation of a rope and instead
directly turn a '&str' into a 'RopeSlice' which is very cheap.
A change to prefer 'RopeSlice' to '&Rope' whenever the rope isn't
modified would be nice, but it would be a very large diff (around 500+
500-). Starting off with just the syntax functions seems like a nice
middle-ground, and we can remove a Rope allocation because of it.

Since regex is almost always injected into other languages,
`pattern_character`s will inherit the highlight for the structure that
injects them (for example `/foo/` in JavaScript or `~r/foo/` in Elixir).
This removes the string highlight when used in the prompt.
We also add `ERROR` node highlighting so that errors in regex syntax
appear in the prompt. This resolves a TODO in the `regex_prompt`
function about highlighting errors in the regex.
We can use tree-sitter-regex highlighting in prompts for entering
regexes, like `search` or `global_search`. The `highlighted_code_block`
function from the markdown component makes this a very small change.
This could be improved in the future by leaving the parsed syntax tree
on the prompt, allowing incremental updates. Prompt lines are usually so
short though and tree-sitter-regex is rather small and uncomplicated,
so that improvement probably wouldn't make a big difference.
* Add initial support for LSP DidChangeWatchedFiles
* Move file event Handler to helix-lsp
* Simplify file event handling
* Refactor file event handling
* Block on future within LSP file event handler
* Fully qualify uses of the file_event::Handler type
* Rename ops field to options
* Revert newline removal from helix-view/Cargo.toml
* Ensure file event Handler is cleaned up when lsp client is shutdown
The helix snap now gets aliased to hx by default at installation time,
so manual aliasing should no longer be required.
