The LSP spec has this to say about initialize:
> Until the server has responded to the `initialize` request with an
> `InitializeResult`, the client must not send any additional requests
> or notifications to the server.
(https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initialize)
The spec is not really explicit about how to handle this scenario.
Before a client sends the 'initialize' request we are allowed to send an
'exit' notification, but after 'initialize' we can't send any requests
(like shutdown) or notifications (like exit). So my intepretation is
that we should forcefully close the server in this state.
This matches the behavior of Neovim's built-in LSP client:
5ceb2238d3/runtime/lua/vim/lsp.lua (L1610-L1628)
The spec explicitly disallows publishDiagnostic to be sent before
the initialize response:
> ... the server is not allowed to send any requests or notifications to
> the client until it has responded with an InitializeResult ...
(https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initialize)
But if a non-compliant server sends this we currently panic because we
'.expect()' the server capabilities to be known to fetch the position
encoding. Instead of panicking we can discard the notification and log
the non-compliant behavior.

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.
Call as bytes before slicing, that way you can take bytes that aren't
aligned to chars. Should technically also be slightly faster since you
don't have to check alignment...
Merges the code for the Picker and FilePicker into a single Picker that
can show a file preview if a preview callback is provided. This change
was mainly made to facilitate refactoring out a simple skeleton of a
picker that does not do any filtering to be reused in a normal Picker
and a DynamicPicker (see #5714; in particular [mikes-comment] and
[gokuls-comment]).
The crux of the issue is that a picker maintains a list of predefined
options (eg. list of files in the directory) and (re-)filters them every
time the picker prompt changes, while a dynamic picker (eg. interactive
global search, #4687) recalculates the full list of options on every
prompt change. Using a filtering picker to drive a dynamic picker hence
does duplicate work of filtering thousands of matches for no reason. It
could also cause problems like interfering with the regex pattern in the
global search.
I tried to directly extract a PickerBase to be reused in Picker and
FilePicker and DynamicPicker, but the problem is that DynamicPicker is
actually a DynamicFilePicker (i.e. it can preview file contents) which
means we would need PickerBase, Picker, FilePicker, DynamicPicker and
DynamicFilePicker and then another way of sharing the previewing code
between a FilePicker and a DynamicFilePicker. By merging Picker and
FilePicker into Picker, we only need PickerBase, Picker and
DynamicPicker.
