Rename reset to default (#8114)
Use `default` instead of `reset`, as this is the conventional name for ANSI codes 39/49. The word `reset` should be reserved for ANSI code `0`, which resets both fg and bg colors at once, while also removing all modifiers. While the code uses the value name `Reset`, this is misleading and should not leak into the user space.

Michael Davis 4555a6b433 Reimplement clipboard commands in terms of special regs
Since the clipboard provider now lives on the Registers type, we want
to eliminate it from the Editor. We can do that and clean up the
commands that interact with the clipboard by calling regular yank,
paste and replace impls on the clipboard special registers.

Eventually the clipboard commands could be removed once macro keybinding
is supported.

Michael Davis 2d838d729c Preview the latest value for regular registers
This fixes a discrepancy between regular registers which are used for
yanking multiple values (for example via `"ay`) and regular registers
that store a history of values (for example `"a*`).

Previously, the preview shown in `select_register`'s infobox would show
the oldest value in history. It's intuitive and useful to see the most
recent value pushed to the history though.

We cannot simply switch the preview line from `values.first()`
to `values.last()`: that would fix the preview for registers
used for history but break the preview for registers used to yank
multiple values. We could push to the beginning of the values with
`Registers::push` but this is wasteful from a performance perspective.
Instead we can have `Registers::read` return an iterator that
returns elements in the reverse order and reverse the values in
`Register::write`. This effectively means that `push` adds elements to
the beginning of the register's values. For the sake of the preview, we
can switch to `values.last()` and that is then correct for both usage-
styles. This also needs a change to call-sites that read the latest
history value to switch from `last` to `first`.

Michael Davis baceb02a09 Use refactored Registers type
This is an unfortunately noisy change: we need to update virtually all
callsites that access the registers. For reads this means passing in the
Editor and for writes this means handling potential failure when we
can't write to a clipboard register.

Michael Davis 0f19f282cf Add system & primary clipboards as special registers
These special registers join and copy the values to the clipboards with
'*' corresponding to the system clipboard and '+' to the primary as
they are in Vim. This also uses the trick from PR6889 to save the values
in the register and re-use them without joining into one value when
pasting a value which was yanked and not changed.

These registers are not implemented in Kakoune but Kakoune also does
not have a built-in clipboard integration.

Michael Davis da2afe7353 Add '#' and '.' special registers
These come from Kakoune:

* '#' is the selection index register. It's read-only and produces the
  selection index numbers, 1-indexed.
* '.' is the selection contents register. It is also read-only and
  mirrors the contents of the current selections when read.

We switch the iterators returned from Selection's `fragments` and
`slices` methods to ExactSizeIterators because:

* The selection contents register can simply return the fragments
  iterator.
* ExactSizeIterator is already implemented for iterators over Vecs, so
  it's essentially free.
* The `len` method can be useful on its own.

Michael Davis 5eb1a25d8a Refactor Registers to take Editor
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.

Michael Davis 98ef05d768 Prefer RopeSlice to &Rope in helix_core::syntax
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.

(Updated) Apply motion API refinements (#6078)
* _apply_motion generalization where possible

API encourages users to not forget setting `editor.last_motion` when
applying a motion. But also not setting `last_motion` without applying a
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`.

* `LastMotion` type alias for `Option<Arc<dyn Fn(&mut Editor)>>`

* Take motion rather than cloning it.

Co-authored-by: Michael Davis <mcarsondavis@gmail.com>

* last_motion as Option<Motion>.

* Use `Box` over `Arc` for `last_motion`.

Mark buffers created from stdin as modified (#7431)
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.

Philipp Mildenberger 71551d395b Adds support for multiple language servers per language.
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.

feat(debug): highlight current line (#5957)
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.

Pascal Kuthe 72b9311678 fix view anchors not at start of a visual line
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 (#5411)
* 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

Pascal Kuthe 8cb7cdfd7a discard stale completion requests
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.

Pascal Kuthe e8898fd9a8 store multiple snapshots on the document at once
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.

Pascal Kuthe 2588fa3710 save selection before completion savepoint
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)

Softwrapping improvements (#5893)
* 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.

* fix typos

Co-authored-by: Jonathan Lebon <jonathan@jlebon.com>

* Add text-width to config.toml

* text-width: update setting documentation

* rename leftover config item

* remove leftover max-line-length occurrences

* 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.

* Revert "Make `text-width` optional in editor config"

This reverts commit b247d526d6.

* soft-wrap: allow per-language overrides

* Update book/src/configuration.md

Fix scrolloff at view bottom (#6142)
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.

feat(dap): send Disconnect if Terminated event received (#5532)
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.

[discon-spec]: https://microsoft.github.io/debug-adapter-protocol/specification#Requests_Disconnect

Closes: #4674
