This sets up a new Registers type that will allow us to expand support
for special registers. (See the child commits.)
We start simple with the regular (`Vec<String>`) registers and the
simplest special register, the black hole. In the child commits we
will expand these match arms with more special registers.
The upcoming special registers will need a few things that aren't
possible with the current Registers type in helix-core:
* Access to the `Editor`. This is only necessary when reading from
registers, so the `&Editor` parameter is only added to
`Registers::read`.
* Returning owned values. Registers in helix-core returns references
to the values backed by the `Vec<String>` but future special registers
will need to return owned values. We refactor the return value of the
read operations to give `Cow<str>`s and iterators over those.
* Returning a `Result` for write/push functions. This will be used by
the clipboard special registers.
Pascal and I discussed this and we think it's generally better to
take a 'RopeSlice' rather than a '&Rope'. The code block rendering
function in the markdown component module is a good example for how
this can be useful: we can remove an allocation of a rope and instead
directly turn a '&str' into a 'RopeSlice' which is very cheap.
A change to prefer 'RopeSlice' to '&Rope' whenever the rope isn't
modified would be nice, but it would be a very large diff (around 500+
500-). Starting off with just the syntax functions seems like a nice
middle-ground, and we can remove a Rope allocation because of it.

API encourages users to not forget setting `editor.last_motion` when

motion first.
* (rename) will_find_char -> find_char
method name makes it sound like it would be returning a boolean.
* use _apply_motion in find_char
Feature that falls out from this is that repetitions of t,T,f,F are
saved with the context extention/move and count. (Not defaulting to extend
by 1 count).
* Finalize apply_motion API
last_motion is now a private field and can only be set by calling
Editor.apply_motion(). Removing need (and possibility) of writing:
`motion(editor); editor.last_motion = motion`
Now it's just: `editor.apply_motion(motion)`
* editor.last_message: rm Box wrap around Arc
* Use pre-existing `Direction` rather than custom `SearchDirection`.

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.
Does not change any behavior other than making the tuple slightly
more idiomatic. Keymap infobox shows key events, then the respective
description. This commit makes sure that order is used from the get go,
rather than flipping it midway.
* Add `helix_lsp::client::Client::supports_feature(&self, LanguageServerFeature)`
* Extend `doc.language_servers_with_feature` to use this method as filter as well
* Add macro `language_server_with_feature!` to reduce boilerplate for non-mergeable language server requests (like goto-definition)
* Refactored most of the `find_map` code to use the either the macro or filter directly via `doc.language_servers_with_feature`
Language Servers are now configured in a separate table in `languages.toml`:
```toml
[langauge-server.mylang-lsp]
command = "mylang-lsp"
args = ["--stdio"]
config = { provideFormatter = true }
[language-server.efm-lsp-prettier]
command = "efm-langserver"
[language-server.efm-lsp-prettier.config]
documentFormatting = true
languages = { typescript = [ { formatCommand ="prettier --stdin-filepath ${INPUT}", formatStdin = true } ] }
```
The language server for a language is configured like this (`typescript-language-server` is configured by default):
```toml
[[language]]
name = "typescript"
language-servers = [ { name = "efm-lsp-prettier", only-features = [ "format" ] }, "typescript-language-server" ]
```
or equivalent:
```toml
[[language]]
name = "typescript"
language-servers = [ { name = "typescript-language-server", except-features = [ "format" ] }, "efm-lsp-prettier" ]
```
Each requested LSP feature is priorized in the order of the `language-servers` array.
For example the first `goto-definition` supported language server (in this case `typescript-language-server`) will be taken for the relevant LSP request (command `goto_definition`).
If no `except-features` or `only-features` is given all features for the language server are enabled, as long as the language server supports these. If it doesn't the next language server which supports the feature is tried.
The list of supported features are:
- `format`
- `goto-definition`
- `goto-declaration`
- `goto-type-definition`
- `goto-reference`
- `goto-implementation`
- `signature-help`
- `hover`
- `document-highlight`
- `completion`
- `code-action`
- `workspace-command`
- `document-symbols`
- `workspace-symbols`
- `diagnostics`
- `rename-symbol`
- `inlay-hints`
Another side-effect/difference that comes with this PR, is that only one language server instance is started if different languages use the same language server.
When re requesting a completion that already has a selected item we
reuse that selections savepoint. However, the selection has likely
changed since that savepoint which requires us to use the selection
from that savepoint
Add new theme highlight keys, for setting the colour of the breakpoint
character and the current line at which execution has been paused at.
The two new keys are `ui.highlight.frameline` and `ui.debug.breakpoint`.
Highlight according to those keys, both the line at which debugging
is paused at and the breakpoint indicator.
Add an indicator for the current line at which execution is paused
at, themed by the `ui.debug.active` theme scope. Update various themes
to showcase how the new functionality works.
Better icons are dependent on #2869, and as such will be handled in the
future, once it lands.

The top of a view is marked by a char idx anchor. That char idx is
usually the first character of the visual line it's on. We use a char
index instead of a line index because the view may start in the middle
of a line with soft wrapping. However, it's possible to temporarily
endup in a state where this anchor is not the first character of the
first visual line. This is pretty rare because edits usually happen
inside/after the view. In most cases we handle this case correctly.
However, if the cursor is before the anchor (but still in view)
there can be crashes or visual artifacts. This is caused by the fact
that visual_offset_from_anchor (and the positioning code in view.rs)
incorrectly assumed that the (cursor) position is always after the
view anchor if the cursor is in view. But if the anchor is not the
first character of the first visual line this is not the case anymore.
In that case crashes and visual artifacts are possible. This commit
fixes that problem by changing `visual_offset_from_anchor` (and
callsites) to properly consider that case.

* deps: Resolve bitflags 2.0 breaking changes
Bitflags 2.0 release made some breaking changes requiring some small
changes to the Helix codebase.
Almost all of the necessary changes are to manually `#[derive(..)]`
trait implementations which are no longer automatically derived for
all bitflags. All of these were previously automatically derived:
#[derive(PartialEq, Eq, PartialOrd, Ord, Hash, Debug, Clone, Copy]
I have derived the minimum traits for each bitflag type.
The other change was to the `.bits` field. This is now a `.bits()`
method so the usage of this has been updated in the `Borders` type.

* Generalised to multiple runtime directories with priorities
This is an implementation for #3346.
Previously, one of the following runtime directories were used:
1. `$HELIX_RUNTIME`
2. sibling directory to `$CARGO_MANIFEST_DIR`
3. subdirectory of user config directory
4. subdirectory of path to helix executable
The first directory provided / found to exist in this order was used as a
root for all runtime file searches (grammars, themes, queries).
This change lowers the priority of `$HELIX_RUNTIME` so that the user
config runtime has higher priority. More significantly, all of these
directories are now searched for runtime files, enabling a user to override
default or system-level runtime files. If the same file name appears
in multiple runtime directories, the following priority is now used:
1. sibling directory to `$CARGO_MANIFEST_DIR`
2. subdirectory of user config directory
3. `$HELIX_RUNTIME`
4. subdirectory of path to helix executable
One exception to this rule is that a user can have a `themes`
directory directly in the user config directory that has higher piority
to `themes` directories in runtime directories. That behaviour has been
preserved.
As part of implementing this feature `theme::Loader` was simplified
and the cycle detection logic of the theme inheritance was improved to
cover more cases and to be more explicit.
* Removed AsRef usage to avoid binary growth
* Health displaying ;-separated runtime dirs
* Changed HELIX_RUNTIME build from src instructions
* Updated doc for more detail on runtime directories
* Improved health symlink printing and theme cycle errors
The health display of runtime symlinks now prints both ends of the
link.
Separate errors are given when theme file is not found and when the
only theme file found would form an inheritence cycle.
* Satisfied clippy on passing Path
* Clarified highest priority runtime directory purpose
* Further clarified multiple runtime details in book
Also gave markdown headings to subsections.
Fixed a error with table indentation not building
table that also appears present on master.

Completion requests are computed asynchronously to avoid common micro
freezes while editing. This means that once a completion request
completes, the state of the editor might have changed. Currently,
there is a check to ensure we are still in insert mode. However,
we also need to ensure that the view and document hasn't changed
to avoid accidentally using a savepoint with the wrong view/document.
Furthermore, the editor might request a new completion while the
previous completion request hasn't complemented yet. This can
lead to weird flickering or an outdated completion request replacing
a newer completion that has already completed (the LSP server
is not required to process completion requests in order). This change
also needed to ensure determinism/linear ordering so that completion
popup always correspond to the last completion request.
Fixing autocomplete required moving the document savepoint before the
asynchronous completion request. However, this in turn causes new bugs:
If the completion popup is open, the savepoint is restored when the
popup closes (or another entry is selected). However, at that point
a new completion request might already have been created which
would have replaced the new savepoint (therefore leading to incorrectly
applied complies).
This commit fixes that bug by allowing in arbitrary number of
savepoints to be tracked on the document. The savepoints are reference
counted and therefore remain valid as long as any reference to them
remains. Weak reference are stored on the document and any reference
that can not be upgraded anymore (hence no strong reference remain)
are automatically discarded.
Currently, the selection is not saved/restored when completion
checkpoints are applied. This is usually fine because undoing changes
usually restores maps selections back in insert mode. But this is not
always the case and especially problematic in the presence of
multi-cursor completions (since completions are applied relative to
the selection/cursor) and snippets (which can change the selection)
* use max_line_width + 1 during softwrap to account for newline char
Helix softwrap implementation always wraps lines so that the newline
character doesn't get cut off so he line wraps one chars earlier then
in other editors. This is necessary, because newline chars are always
selecatble in helix and must never be hidden.
However That means that `max_line_width` currently wraps one char
earlier than expected. The typical definition of line width does not
include the newline character and other helix commands like `:reflow`
also don't count the newline character here.
This commit makes softwrap use `max_line_width + 1` instead of
`max_line_width` to correct the impedance missmatch.

* Make `text-width` optional in editor config
When it was only used for `:reflow` it made sense to have a default
value set to `80`, but now that soft-wrapping uses this setting, keeping
a default set to `80` would make soft-wrapping behave more aggressively.
* Allow softwrapping to ignore `text-width`
Softwrapping wraps by default to the viewport width or a configured
`text-width` (whichever's smaller). In some cases we only want to set
`text-width` to use for hard-wrapping and let longer lines flow if they
have enough space. This setting allows that.

Fixes a regression introduced in #5420 where a scrolloff of `x - 1`
was used instead if `x` at the bottom of the screen. This was
especially problematic if the scrolloff was set to `0` in that case
the scrolloff behaved as tough set to `-1` and the cursor disappeared
from the view if scrolled to the botoom.
Send a `Disconnect` DAP request if the `Terminated` event is received.
According to the specification, if the debugging session was started by
as `launch`, the debuggee should be terminated alongside the session. If
instead the session was started as `attach`, it should not be disposed of.
This default behaviour can be overriden if the `supportTerminateDebuggee`
capability is supported by the adapter, through the `Disconnect` request
`terminateDebuggee` argument, as described in
[the specification][discon-spec].
This also implies saving the starting command for a debug sessions, in
order to decide which behaviour should be used, as well as validating the
capabilities of the adapter, in order to decide what the disconnect should
do.
An additional change made is handling of the `Exited` event, showing a
message if the exit code is different than `0`, for the user to be aware
off the termination failure.

* rework positioning/rendering, enables softwrap/virtual text
This commit is a large rework of the core text positioning and
rendering code in helix to remove the assumption that on-screen
columns/lines correspond to text columns/lines.
A generic `DocFormatter` is introduced that positions graphemes on
and is used both for rendering and for movements/scrolling.
Both virtual text support (inline, grapheme overlay and multi-line)
and a capable softwrap implementation is included.

The `From<Value>` implementation for `Theme` converted the Value to a
string and re-parsed the string to convert it to
`HashMap<String, Value>` which feels a bit wasteful. This change uses
the underlying `toml::map::Map` directly when the value is a table and
warns about the unexpected `Value` shape otherwise.
This is necessary because toml 0.6.0 changes the Display implementation
for Value::Table so that the `to_string` no longer encodes the value as
a Document, just a Value. So the parse of the Value fails to be decoded
as a HashMap.
The behavior for returning `Default::default` matches the previous
code's behavior except that it did not warn when the input Value was
failed to parse.
`toml::from_slice` has been removed. The CHANGELOG recommends using
`toml::from_str` instead and doing the byte-to-str conversion yourself.
The `toml::toml!` macro has also changed to return the type of the
value declared within the macro body. In the change in
`helix-view/src/theme.rs` this is a `toml::map::Map` (it was a
`toml::Value` previously) allowing us to skip the match and use the
map directly.

The error messages for a theme that failed to be deserialized (or
otherwise failed to load) were covered up by the context/with_context
calls:
* The log message for a bad theme configured in config.toml would only
say "Failed to deserilaize theme"
* Selecting a bad theme via :theme would show "Theme does not exist"
With these changes, we let the TOML deserializer errors bubble up, so
the error messages can now say the line number of a duplicated
key - and that key's name - when a theme fails to load because of a
duplicated key.
Providing a theme which does not exist to :theme still gives a helpful
error message: "No such file or directory."
* Reset mode when changing buffers
This is similar to the change in
e4c9d4082a139aac3aea4506918171b96e81f5b9: reset the editor to normal
mode when changing buffers. Usually the editor is already in normal
mode but it's possible to setup insert-mode keybindings that change
buffers.
* Move normal mode entering code to Editor
This should be called internally in the Editor when changing documents
(Editor::switch) or changing focuses (Editor::focus).
* Add `View::ensure_cursor_in_view_center` to adjust view after searching and jumping
Also `offset_coodrs_to_in_view` was refactored to reduce duplicated position calculations.

Media keys are sent despite `DISAMBIGUATE_ESCAPE_CODES` being unset.
Previously we panicked on these. This change translates the
disambiguated keys from crossterm so that they do not cause a panic.
Previously we removed selections for a closed view on only the
currently focused document. A view might have selections in other
documents though, so the view needs to be removed from all documents.

Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>

Previously, jumplists could grow unchecked. Every transaction is
applied to jumplist selections to ensure that they are up to date
and within document bounds, so this would cause every edit to become
more expensive as jumplist lengths increased throughout a session.
Setting a maximum number of entries limits the cost.
Vim and Neovim limit their jumplists:
* b298fe6cba/src/structs.h (L141)
* e8cc489acc/src/nvim/mark_defs.h (L57)
Notably, Kakoune does not. In Kakoune, changes are applied to jumplist
entries lazily as you hit `<C-o>`/`<C-i>` though, so Kakoune doesn't
have the same growing cost concerns. Kakoune also does not have a
concept of a View which limits the cost further.
Vim and Neovim limit to 100. This seems unreasonably high to me so I've
set this to 30 to start. We can increase if this is problematically
low.
There is some common code between Editor::focus_next and Editor::focus
that can be eliminated by refactoring Tree::focus_next into a function
that only returns the next ViewId.

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`).

Most commands that accept an argument show their current value if no
argument is specified. The `:theme` command previously displayed an
error message in the status bar if not provided with an argument:
```
Theme name not provided
```
It now shows the current theme name in the status bar if no argument is
specified.

* Fix test::print for Unicode
The print function was not generating correct translations when
the input has Unicode (non-ASCII) in it. This is due to its use of
String::len, which gives the length in bytes, not chars.
* Fix multi-code point auto pairs
The current code for auto pairs is counting offsets by summing the
length of the open and closing chars with char::len_utf8. Unfortunately,
this gives back bytes, and the offset needs to be in chars.
Additionally, it was discovered that there was a preexisting bug where
the selection was not computed correctly in the case that the cursor
was:
1. a single grapheme in width
2. this grapheme was more than one char
3. the direction of the cursor is backwards
4. a secondary range
In this case, the offset was not being added into the anchor. This was
fixed.
* migrate auto pairs tests to integration
* review comments
This was not distinguishing the error types when trying a receive on an empty
receiver, which was erroneously causing the sender to be closed when trying to
flush the writes when there were none
