Completion edits - either basic `insert_text` strings or structured
`text_edit`s - are assumed by the LSP spec to apply to the current
cursor (or at least the trigger point). We can use the range (if any)
and text given by the Language Server to create a transaction that
changes all ranges in the current selection though, allowing auto-
complete to affect multiple cursors.

When using undo/redo, the history revision can be decremented. In that
case we should apply the inversions since the given revision in
History::changes_since. This prevents panics with jumplist operations
when a session uses undo/redo to move the jumplist selection outside
of the document.
* Add a test case for updating jumplists across windows
* Apply transactions to all views on history changes
This ensures that jumplist selections follow changes in documents, even
when there are multiple views (for example a split where both windows
edit the same document).
* Leave TODOs for cleaning up View::apply
* Use Iterator::reduce to compose history transactions

Language Servers may signal that they do not support a method in
the initialization result (server capabilities). We can check these
when making LSP requests and hint in the status line when a method
is not supported by the server. This can also prevent crashes in
servers which assume that clients do not send requests for methods
which are disabled in the server capabilities.
There is an existing pattern the LSP client module where a method
returns `Option<impl Future<Output = Result<_>>>` with `None` signaling
no support in the server. This change extends this pattern to the rest
of the client functions. And we log an error to the statusline for
manually triggered LSP calls which return `None`.
d7d0d5ffb7 resolves completion items on
the idle-timeout event. The `Completion::resolve_completion_item`
function blocks on the LSP request though, which blocks the compositor
and in turn blocks the event loop. So until the language server returns
the resolved completion item, Helix is unable to respond to keypresses
or other LSP messages.
This is typically ok since the resolution request is fast but for some
language servers this can be problematic, and ideally we shouldn't be
blocking like this anyways.
When receiving a `completionItem/resolve` request, the Volar server
sends a `workspace/configuration` request to Helix and blocks itself
on the response, leading to a deadlock. Eventually the resolve request
times out within Helix but Helix is locked up and unresponsive in that
window.
This change resolves the completion item without blocking the
compositor.

* removing max line num char limit; adding notes; qualified successors; notes

* adding spacer to gutters default; updating book config entry
* adding view.inner_height(), swap for loop for iterator
* reverting change of current! to view! now that doc is not needed
This changes the completion items to be rendered with shellword
escaping, so a file `a b.txt` is rendered as `a\ b.txt` which matches
how it should be inputted.
* Clamp highlighting range to be within document
This fixes a panic possible when two vsplits of the same document
exist and enough lines are deleted from the document so that one of
the windows focuses past the end of the document.
* Ensure cursor is in view on window change
If two windows are editing the same document, one may delete enough of
the document so that the other window is pointing at a blank page (past
the document end). In this change we ensure that the cursor is within
view whenever we switch to a new window (for example with `<C-w>w`).
* Update helix-term/src/ui/editor.rs

This is mostly for the sake of the diagnostics pickers: without
rendering the diagnostic styles, it's hard to tell where the entries
in the picker are pointing to.
Some language servers may not send the `documentation` field if it
is expensive to compute. Clients can request the missing field with
a completionItem/resolve request.
In this change we use the idle-timeout event to ensure that the current
completion item is resolved.

Instead of repeatedly checking if it is in_bounds, calculate the
max_indent beforehand and just loop. I added a debug_assert to "prove"
that it never tries drawing out of bounds.
Better performance, and otherwise very long lines with lots of tabs
will wrap around the u16 and come back on the other side, messing up
the beginning skip_levels.
The debug assertion that document diagnostics are sorted incorrectly
panics for cases like `[161..164, 162..162]`. The merging behavior
in the following lines that relies on the assertion only needs the
input ranges to be sorted by `range.start`, so this change simplifies
the assertion to only catch violations of that assumption.
Here we separate the diagnostics by severity and then overlay the Vec
of spans for each severity on top of the highlights. The error
diagnostics end up overlaid on the warning diagnostics, which are
overlaid on the hints, overlaid on info, overlaid on any other severity
(default), then overlaid on the syntax highlights.
This fixes two things:
* Error diagnostics are now always visible when overlapped with other
diagnostics.
* Ghost text is eliminated.
* Ghost text was caused by duplicate diagnostics at the EOF:
overlaps within the merged `Vec<(usize, Range<usize>)>` violate
assumptions in `helix_core::syntax::Merge`.
* When we push a new range, we check it against the last range and
merge the two if they overlap. This is safe because they both
have the same severity and therefore highlight.
The actual merge is skipped for any of these when they are empty, so
this is very fast in practice. For some data, I threw together an FPS
counter which renders as fast as possible and logs the renders per
second.
With no diagnostics, I see an FPS gain from this change from 868 FPS
to 878 (+1.1%) on a release build on a Rust file. On an Erlang file
with 12 error diagnostics and 6 warnings in view (233 errors and 66
warnings total), I see a decrease in average FPS from 795 to 790
(-0.6%) on a release build.
It is easy to forget to call `Document::apply` and/or `View::apply` in
the correct order. This commit introduces a helper function which
closes over both calls.
This change adds View::apply calls for all Document::apply call-sites,
ensuring that changes to a document do not leave invalid entries in
the View's jumplist.
