fsync(2) is a somewhat expensive operation that flushes writes to the
underlying disk/SSD. It's typically used by databases to ensure that
writes survive very hard failure scenarios like your cat kicking the
plug out of the wall. Synchronizing isn't automatically done by
`flush`ing (from the `std::io::Write` or `tokio::io::AsyncWriteExt`
traits). From the [`tokio::fs::File`] moduledocs:
> To ensure that a file is closed immediately when it is dropped, you
> should call `flush` before dropping it. Note that this does not ensure
> that the file has been fully written to disk; the operating system
> might keep the changes around in an in-memory buffer. See the
> `sync_all` method for telling the OS to write the data to disk.

Without a serializer, we drop the custom alphabet when making config
modifications like with `:set`. For example before this commit,
`:set mouse false` would reset a custom alphabet to the default.
This patch merges the last child of a container node to the parent. This
avoids the bug where uneven spaced Views would be created. To reproduce:
1. `vsplit`
2. `split`
3. `quit`
4. `vsplit`
With this patch the bug cannot be seen anymore.
In the `reload-all` command, we should not stop reloading the documents
if one error is found. Instead, we should report the error and continue
trying to reload the current open documents. This is useful in cases
where a backing file does not exist temporarily (e.g. when editing a git
patch in the outstanding chain that doesn't have a file just yet).
This change also remove the error messages in the cases where the
backing is `None`, like in new docs or `tutor`.

URIs need to be normalized to be comparable. For example a language
server could send a URI for a path containing '+' as '%2B' but we might
encode this in something like 'Document::url' as just '+'. We can
normalize the URI straight into a PathBuf though since this is the only
value we compare these diagnostics URIs against. This also covers
edge-cases like windows drive letter capitalization.
`syn_loader` was replaced rather than interior value being replace,
old value was still being referenced and not updated after `:config-refresh`.
By using `ArcSwap` like for `config`, each `.load()` call will return the most
updated value.

Currently, helix implements operations which change the paths of files
incorrectly and inconsistently. This PR ensures that we do the following
whenever a buffer is renamed (`:move` and workspace edits)
* always send did_open/did_close notifications
* send will_rename/did_rename requests correctly
* send them to all LSP servers not just those that are active for a
buffer
* also send these requests for paths that are not yet open in a buffer (if
triggered from workspace edit).
* only send these if the server registered interests in the path
* autodetect language, indent, line ending, ..
This PR also centralizes the infrastructure for path setting and
therefore `:w <path>` benefits from similar fixed (but without didRename)
We use `which::which` in many crates, so `which` was a separate
dependency across all of them. We can centralize `which` into the
stdx crate so it's easy for all crates to depend on it.
I also moved the rest of `helix-view/src/env.rs` into helix-stdx's
`env` module since it only contained a thin wrapper around `which`
and `std::env`.
helix-stdx is meant to carry extensions to the stdlib or low-level
dependencies that are useful in all other crates. This commit starts
with all of the path functions from helix-core and the CWD tracking that
lived in helix-loader.
The CWD tracking in helix-loader was previously unable to call the
canonicalization functions in helix-core. Switching to our custom
canonicalization code should make no noticeable difference though
since `std::env::current_dir` returns a canonicalized path with
symlinks resolved (at least on unix).
Diagnostics are currently extended if text is inserted at their end. This is
desirable when inserting text after an identifier. For example consider:
let foo = 2;
--- unused variable
Renaming the identifier should extend the diagnostic:
let foobar = 2;
------ unused variable
This is currently implemented in helix but as a consequence adding whitespaces
or a type hint also extends the diagnostic:
let foo = 2;
-------- unused variable
let foo: Bar = 2;
-------- unused variable
In these cases the diagnostic should remain unchanged:
let foo = 2;
--- unused variable
let foo: Bar = 2;
--- unused variable
As a heuristic helix will now only extend diagnostics that end on a word char
if new chars are appended to the word (so not for punctuation/ whitespace).
The idea for this mapping was inspired for the word level tracking vscode uses
for many positions. While VSCode doesn't currently update diagnostics after
receiving publishDiagnostic it does use this system for inlay hints for example.
Similarly, the new association mechanism implemented here can be used for word
level tracking of inlay hints.
A similar mapping function is implemented for word starts. Together
these can be used to make a diagnostic stick to a word. If that word
is removed that diagnostic is automatically removed too. This is the exact
same behavior VSCode inlay hints eixibit.

Use `default` instead of `reset`, as this is the conventional name for ANSI codes 39/49. The word `reset` should be reserved for ANSI code `0`, which resets both fg and bg colors at once, while also removing all modifiers. While the code uses the value name `Reset`, this is misleading and should not leak into the user space.

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.
(Also see PR5577.)

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.
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.

* _apply_motion generalization where possible
API encourages users to not forget setting `editor.last_motion` when
applying a motion. But also not setting `last_motion` without applying a
motion first.
* (rename) will_find_char -> find_char
method name makes it sound like it would be returning a boolean.
* use _apply_motion in find_char
Feature that falls out from this is that repetitions of t,T,f,F are
saved with the context extention/move and count. (Not defaulting to extend
by 1 count).
* Finalize apply_motion API
last_motion is now a private field and can only be set by calling
Editor.apply_motion(). Removing need (and possibility) of writing:
`motion(editor); editor.last_motion = motion`
Now it's just: `editor.apply_motion(motion)`
* editor.last_message: rm Box wrap around Arc
* Use pre-existing `Direction` rather than custom `SearchDirection`.
* `LastMotion` type alias for `Option<Arc<dyn Fn(&mut Editor)>>`
* Take motion rather than cloning it.

This resolves some confusing behavior where a scratch document created
by piping into hx is discarded when navigating away from that document.
We discard any scratch documents that are not modified and the original
`Editor::new_file_from_stdin` would create unmodified documents. We
refactor this function to create an empty document first and then to
apply the text from stdin as a change.
