This matches the behavior described by the EditorConfig spec for its
`insert_final_newline` option:
> Editors must not insert newlines in empty files when saving those
> files, even if `insert_final_newline = true`.

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)
Render rulers before the cursor to ensure that the cursor, when over
a ruler, is not hidden from view. Without this, you typically end up
with 1) foreground text that is the same as the background if the
ruler doesn't already have a foreground and 2) no visible cursor,
because the ruler's background color took precedence. By moving the
rulers before the cursor, this ensures that the theme is still rendered
more or less the way one would visually expect things to turn out.
This follows a pattern used in the signature help request for example.
Moving the json deserialization into the return future of
`text_document_hover` makes the types easier for callers to work with.
The info log within `process_request_response` duplicated the body of
the JSON message printed earlier by the transport which was confusing.
The error log in the completion handler was easy to hit during normal
use and is not actually an error - dropping is the graceful way to
handle changes occurring while completion requests are in flight.
This is not consequential now but when we switch to the new highlighter
we will want the theme to be set (and the loader's `scopes` to be set
based on the theme) before parsing a document. Previously `set_theme`
came after the loading of documents, so documents would be missing
locals highlights after being loaded and before the first edit.
`:lsp-stop` should consider only the set of active language servers for
a document. `:lsp-restart` though may be used to start up a language
server that crashed or was manually stopped, so it needs to consider the
language servers in config instead.
This change inlines the `valid_lang_servers` function into `:lsp-stop`
and `:lsp-restart` and changes `:lsp-restart` to check the doc's config
rather than active language servers. `:lsp-restart` now also does not
need to clone the language server names as strings since it borrows from
the config and arguments rather than `Document`. The completer has also
been split into two - one matching active language servers, used by
`:lsp-stop`, and the other matching configured language servers, used by
`:lsp-restart`.
This also removes the part of `:lsp-restart` which bailed if a language
server failed to be restarted (for example because it is not installed).
There might be multiple language servers configured for a language and
only one installed. In that case the `:lsp-restart` should be considered
successful even if not all servers could be started. Bailing prevented
any language servers which could start from being attached to the
document. Instead errors are collected and emitted at the end.
Previously all register selection info boxes had "Registers" as the
title. That was particularly confusing for `copy_between_registers`
which presents two info boxes back-to-back.
The application held onto these since their introduction in ce97a2f0 but
the Arcs are duplicated between Application and Editor - we can store it
only on Editor without issue.
There is no functional change to the move - it's just moving the code
into helix-view under a new method `Editor::handle_lsp_diagnostics` -
thought there is a typo fix, the removal of an unnecessary clone (for
the document's language config) and the removal of some nesting.

This causes the infobox to disappear even when you type a non-character
key like escape. For example `"<esc>` now clears the infobox where
before it was left hanging.
Path completion items always have documentation but future core (i.e.
non-LSP) completions may not always have documentation - for example
word completion from the current buffer.
Completions are not specific to LSP anymore. In the child commits we
will expand on the types in this module so this refactor is done
eagerly to minimize changes later.
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.

This improves the display of the keymap popup for example, so that if
you bind a key like `C-x = ":buffer-close"` under the `<space>` menu,
the infobox shows "Close the current buffer." rather than `:buffer-close
[]`.
This simplifies the hover component by eagerly converting all
`lsp::Hover` responses into `Markdown`s. Previously we cached the
current `Markdown` and created a new `Markdown` when switching the
active response. Instead we can consume the `lsp::Hover` and avoid some
clones of its inner types.
The Hover component is used as the inner contents of a Popup. The Popup
should be doing calculations based on whether popup_borders is
configured and not Hover. This fixes an issue with hover rendering when
the popup border option is enabled for popups.
Fixes#12742
The language server may return `None` for a definition/reference
request. The parent commits introduced a regression for these commands
when a server did not provide locations. With this change a server may
respond with `null` and its locations will instead not be considered.
Fixes#12732
This covers all goto-definition-like commands: declaration, definition,
type definition and implementation.
Closes#11689

<https://github.com/helix-editor/helix/pull/11486> introduced a Location
type in the LSP commands module which unified helpers like
`jump_to_location`. This change moves `OffsetEncoding` onto that type.
`SymbolInformationItem` and `PickerDiagnostic` already had fields for
carrying the offset encoding. We would want a similar setup for goto
definition/references as well (for supporting multiple language servers
with that feature) but those use the `Location` type. By moving
`OffsetEncoding` onto `Location` we make future changes to allow
mulitple language servers possible for goto definition/references
features and also simplify some calls for symbols and diagnostics.
The positions passed to `Transaction::change_by_selection` should be
character indexes. `edit_diff` is meant to track the number of
characters that should be deleted to erase the file name that has been
typed so far (if any). Mistakenly this was using `str::len` which is
the byte count. This fixes a bug that could cause more text to be
deleted than intended or a panic when completing a directory with
multi-byte characters like 'éclair'.
This change also moves the `edit_diff` binding out of the loop since
it's now performing some non-trivial work (counting characters, where
before it was just accessing the pre-computed number of bytes).
Previously you could use `<A-a><A-b>` to jump to a label "ab". We should
not treat characters with modifiers the same as characters without.
With this change the `<A-a>` input exits out of the jumping on-next-key.
Fixes#12695
The new `RopeSliceExt::ceil_char_boundary` from the parent commits can
be used to implement `RopeSliceExt::byte_to_next_char` when used with
`RopeSlice::byte_to_char`. That function had only one caller and that
caller will eventually disappear when we switch to Ropey v2 and drop
character indexing, so we can drop `byte_to_next_char` now and replace
its caller with `byte_to_char` plus `ceil_char_boundary`.
This change keeps the unit tests for `byte_to_next_char` and checks them
against a polyfill of `byte_to_char` plus `ceil_char_boundary` to ensure
that `byte_to_next_char`'s intended behavior is not changed.
This is a good example use-case of the `floor_char_boundary` and
`ceil_char_boundary` functions added in the parent commit. In the
single-width, single-selection case in `goto_file` we cap the search
to either the current line or 1000 bytes before or after the cursor
(whichever case comes earlier). That byte index might not lie on a
character boundary so it needs to be fixed to either the prior or
later boundary.

This should help debug formatting failures when using external
formatters in the future. Previously we didn't log anything when an
external formatter failed despite having a custom error type for it.
This is partially a style commit:
* Pull more bindings out the `change_by_selection` closure like the
line-ending string and the comment tokens used for continuation.
* Prefer `Editor::config` to `Document`'s config.
The rest is changes to places where `insert_newline` may allocate.
The first is to move `new_text` out of the `change_by_selection`
closure, reusing it between iterations. This is not necessarily always
an improvement as we need to clone the text for the return type of the
closure. `SmartString`'s `From<String>` implementation reuses the
allocation when the string is too long to inline and drops it if it is
short enough to inline though which can be wasteful. `From<&String>`
clones the string's allocation only when it is too long to be inlined,
so we save on allocations for any `new_text` short enough to be inlined.
The rest is changes to `new_text.reserve_exact`. Previously calls to
this function in this block mixed up character and byte indexing by
treating the length of the line-ending as 1. `reserve_exact` takes a
number of bytes to reserve and that may be 2 when `line_ending` is a
CRLF. A call to `reserve_exact` is also added to the branch used when
continuing line comments.
#12177 changed `insert_newline`'s behavior to trim any trailing
whitespace on a line which came before a cursor. `insert_newline` would
previously never delete text. Even the whitespace stripping behavior in
#4854 worked by inserting text - a line ending at the beginning of the
line. `global_offs`, a variable that tracks the number of characters
inserted between iterations over the existing selection ranges, was not
updated to also account for text deleted by the trimming behavior,
causing cursors to be offset by the amount of trailing space deleted
and causing panics in some cases.
To fix this we need to subtract the number of trimmed whitespace
characters from `global_offs`. `global_offs` must become an `isize`
(was a `usize`) because it may become negative in cases where a lot of
trailing whitespace is trimmed. Integration tests have been added for
each of these cases.

For example `:cd README.md` would say "Not a directory" but would not
print the directory name. Now the error message includes some context
about the operation and requested directory.
Reproduction:
* `hx`
* Open any file in a split (`<space>f` and choose anything with `<C-v>`)
* Close the split with `<C-w>q`
* Open up the buffer picker and look the file you opened previously
Previously the preview was empty in this case because the Document's
`selections` hashmap was empty and we returned early, giving `None`
instead of a FileLocation. Instead when the Document is not currently
open in any view we can show the document but with no range highlighted.
Instantiating EditorView is a lot of machinery which is unnecessary:
the default keymap is exposed through the `default` function in the
keymap module.
Previously we replaced line-endings in pasted text to the document
line-ending for some values in paste commands. We missed the `repeat`
values in paste though and didn't do any replacement in the replace
command.
Along with this change I've refactored the replace command to avoid
intermediary collections. We previously eagerly collected the values
from the input register as a `Vec<String>` but we can avoid both of
those conversions and only allocate for the conversion to a `Tendril`.
We can also switch from `str::repeat` to a manual implementation to
avoid the intermediary conversion to a String - this avoids an extra
allocation in the common case (i.e. no count).
