in the past DocumentDidChange and SelectionDidChange events were implemented in
a simplistic manner to get a simple prototype out. However, if you want to use
these events in more complex scenarios with interdependencies between the two
handlers the system fell short.
The `SelectionDidChange` event was dispatched before the DocumentDidChange (and
not at all if the selection wasn't manually set) so any handlers that wants to
track selection was not able to map their ranges yet.
The reason for this was actually the way that apply_impl was structured. The
function was slightly refactored to address these problems and enable moving
other range mappings to event handlers.
These changes are ported from
<https://redirect.github.com/helix-editor/helix/pull/9801>. It's a
cleanup of `Document::apply_impl` that uses some early returns to
reduce nesting and some reordering of the steps. The early returns
bail out of `apply_impl` early if the transaction fails to apply or
if the changes are empty (in which case we emit the SelectionDidChange
event). It's a somewhat cosmetic refactor that makes the function easier
to reason about but it also makes it harder to introduce bugs by mapping
positions through empty changesets for example.

* replicate t-monaghan's changes
* remove View.offset in favour of Document.view_data.view_position
* improve access patterns for Document.view_data
* better borrow checker wrangling with doc_mut!()
* reintroduce ensure_cursor_in_view in handle_config_events
since we sorted out the borrow checker issues using partial borrows,
there's nothing stopping us from going back to the simpler implementation
* introduce helper functions on Document .view_offset, set_view_offset
* fix rebase breakage
This commit brings the text decoration API inline with the
LineAnnotation API (so they are consistent) resulting in a single
streamlined API instead of multiple ADHOK callbacks.
This introduces a custom URI type in core meant to be extended later
if we want to support other schemes. For now it's just a wrapper over a
PathBuf. We use this new URI type to firewall `lsp::Url`. This was
previously done in 8141a4a but using a custom URI type is more flexible
and will improve the way Pickers handle paths for previews in the child
commit(s).

Saving while in insert mode causes issues with the modification
indicator and this is very easy to reproduce with the current state of
the auto-save hook. We can tweak the hook slightly to await the mode
switch out of insert mode to perform the save.
The debounce is preserved: if you save and then immediately exit insert
mode the debounce will be respected. If the debounce lapses while you
are in insert mode, the save occurs as you switch out of insert mode
immediately.

- Remove unneccessary field
- Remove blocking save
* Improve auto-save configuration
Auto save can be configured to trigger on focus loss:
```toml
auto-save.focus-lost = true|false
```
and after a time delay (in milli seconds) since last keypress:
```toml
auto-save.after-delay.enable = true|false
auto-save.after-delay.timeout = [0, u64::MAX] # default: 3000
```
* Remove boilerplate and unnecessary types
* Remove more useless types
* Update docs for auto-save.after-delay
* Fix wording of (doc) comments relating to auto-save
* book: Move auto-save descriptions to separate section

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.
[`tokio::fs::File`]: https://docs.rs/tokio/latest/tokio/fs/struct.File.html
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`.
* feat: add 'file-abs-path' to statusline (#4434)

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`.
