Add fuzzy searching.
All items (in this case, lines) are shown at once since that's the norm in fuzzy searchers.
The unsafe is used to avoid extra memory allocations. If we use the text() method on the Document and get the Rope, we still need to iterate over the lines, but we will have to allocate a String every time so we can trim it, and also add it to the results to be injected later into the Injector. Using this feature in a file with 10000 lines would allocate 10000 times!
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.
The point of ghost transactions is to avoid notifying language servers
about changes since the change is meant to be temporary. This is used
for completion while selecting items in the menu: updating the language
server would mess up incomplete completions.
When a document is changed by a ghost transaction the language server
will not be notified so its understanding of the document will not be
synchronized and any positions it sends may be out-of-date. So we should
avoid triggering a request for new document color information when a
document is changed by a ghost transaction.
Even though there is a check for `is_like_msvc`, when setting `CXX` to
`clang++` this will miss that check and try to use `-fPIC`, which is an
invlaid flag for the target.
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`.
