On Windows for example the behavior of this function typically diverges
from the usual behavior on Unix. Instead of checking that the inserted
string starts with `'\n'` (untrue for for CRLF line endings) we need to
check that the first grapheme cluster in the string is a line ending.
(All line endings are single grapheme clusters.)
This type also exists on `Editor`. This change brings it to the
`Document` as well because the replacement for `Syntax` in the child
commits will eliminate `Syntax`'s copy of `syn_loader`. `Syntax` will
also be responsible for returning the highlighter and query iterators
(which will borrow the loader), so the loader must be separated from
that type.
In the long run, when we make a larger refactor to have
`Document::apply` be a function of the `Editor` instead of the
`Document`, we will be able to drop this field on `Document` - it is
currently only necessary for `Document::apply`. Once we make that
refactor, we will be able to eliminate the surrounding `Arc` in
`Arc<ArcSwap<syntax::Loader>>` and use the `ArcSwap` directly instead.
When closing a document we must wait until all views have been updated
first - either replacing their current document or closing the view -
before we remove the document from the `documents` map. The
`Editor::_refresh` helper is called by `Editor::close`. It accesses each
View's Document to sync changes and ensure that the cursor is in view.
When closing multiple Views at once, `Editor::_refresh` will attempt
to access the closing Document while refreshing a to-be-closed View.
This fixes a regression from 6da1a79d80. `:buffer-close` on an
unmodified document would cause later panics since the document should
not have been removed. Instead of eagerly removing the document on the
first line we need to wait until we've checked that it's unmodified.
Previously the `call` helper (and its related functions) returned a
`serde_json::Value` which was then decoded either later in the client
(see signature help and hover) or by the client's caller. This led to
some unnecessary boilerplate in the client:
let resp = self.call::<MyRequest>(params);
Some(async move { Ok(serde_json::from_value(resp.await?)?) })
and in the caller. It also allowed for mistakes with the types. The
workspace symbol request's calling code for example mistakenly decoded a
`lsp::WorkspaceSymbolResponse` as `Vec<lsp::SymbolInformation>` - one of
the untagged enum members (so it parsed successfully) but not the
correct type.
With this change, the `call` helper eagerly decodes the response to a
request as the `lsp::request::Request::Result` trait item. This is
similar to the old helper `request` (which has become redundant and has
been eliminated) but all work is done within the same async block which
avoids some awkward lifetimes. The return types of functions like
`Client::text_document_range_inlay_hints` are now more verbose but it is
no longer possible to accidentally decode as an incorrect type.
Additionally `Client::resolve_code_action` now uses the `call_with_ref`
helper to avoid an unnecessary clone.
This adds events for:
* a document being opened
* a document being closed
* a language server sending the initialized notification
* a language server exiting
and also moves some handling done for these scenarios into hooks,
generally moving more into helix-view. A hook is also added on
`DocumentDidChange` which sends the `text_document_did_change`
notification - this resolves a TODO in `document`.
This resolves a TODO in the core diagnostic module to refactor this
type. It was originally an alias of `LanguageServerId` for simplicity.
Refactoring as an enum is a necessary step towards introducing
"internal" diagnostics - diagnostics emitted by core features such as
a spell checker. Fully supporting this use-case will require further
larger changes to the diagnostic type, but the change to the provider
can be made first.
Note that `Copy` is not derived for `DiagnosticProvider` (as it was
previously because `LanguageServerId` is `Copy`). In the child commits
we will add the `identifier` used in LSP pull diagnostics which is a
string - not `Copy`.
These match the equivalent options in VSCode. `trim_trailing_whitespace`
is also the name used by EditorConfig.
* `trim-final-newlines` trims any extra line endings after the final one
* `trim-trailing-whitespace` trims any trailing whitespace (but not
empty lines)
Previously LSP notifications were sent within a future and most callers
used a `tokio::spawn` to send the notification, silently discarding any
failures like problems serializing parameters or sending on the channel.
It's possible that tokio could schedule futures out of intended order
though which could cause notifications where order is important, like
document synchronization, to become partially shuffled. This change
removes the future wrapper and logs all internal failures.
Also included in this commit is the same change for `Client::reply`
which was also unnecessarily wrapped in a future.

In the case of network file systems, if the server time is ahead
of the local system time, then helix could annoy with messages
that the file has already been modified by another application.
* 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).

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.
