* _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.

* last_motion as Option<Motion>.
* Use `Box` over `Arc` for `last_motion`.

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.
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.

Resolves issue #6888 by adding a command to join all selections and yank
them to the specified register. The typed command takes an argument as
the separator to use when joining the selections.
Previously a count or register selection would be lost while opening
the command palette. This change allows using a register selection or
count in any command chosen from the command palette.
Previously the register selection (via `"`) would be lost in the middle
of any key sequence longer than one key. For example, `<space>f` would
clear the register selection after the `<space>` making it inaccessible
for the `file_picker` command.
This behavior does not currently have any effect in the default keymap
but might affect custom keymaps. This change aligns the behavior of the
register with count. Making this change allows propagating the register
to the `command_palette` (see the child commit) or other pickers should
we decide to use registers in those in the future. (Interactive global
search for example.)
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.
* chore: avoid format! call with argument when useless
* feat: also clear diagnostics for unopened documents when exiting an LSP
* feat: we already worked on `self.editor.diagnostics` no need to redo the checks
* Add command for merging non-consecutive ranges
* Add `merge_selections` command to book
* Simplify `merge_ranges`
Heeded the advice of @the-mikedavis to stop iterating over all ranges and simply merge the first and the last range, as the invariants of `Selection` guarantee that the list of ranges is always sorted and never empty.
* Clarify doc comment of `merge_ranges`
* 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.
There was an issue with autocompletion of a path with a space in it.
Before:
:o test\ dir -> <TAB> -> test\ dirfile1
After:
:o test\ dir -> <TAB> -> test\ dir\file1
Currently, when forward deleting (`delete_char_forward` bound to `del`,
`delete_word_forward`, `kill_to_line_end`) the cursor is moved to the
left in append mode (or generally when the cursor is at the end of the
selection). For example in a document `|abc|def` (|indicates selection)
if enter append mode the cursor is moved to `c` and the selection
becomes: `|abcd|ef`. When deleting forward (`del`) `d` is deleted. The
expectation would be that the selection doesn't shrink so that `del`
again deletes `e` and then `f`. This would look as follows:
`|abcd|ef`
`|abce|f`
`|abcf|`
`|abc |`
This is inline with how other editors like kakoune work.
However, helix currently moves the selection backwards leading to the
following behavior:
`|abcd|ef`
`|abc|ef`
`|ab|ef`
`ef`
This means that `delete_char_forward` essentially acts like
`delete_char_backward` after deleting the first character in append
mode.
To fix the problem the cursor must be moved to the right while deleting
forward (first fix in this commit). Furthermore, when the EOF char is
reached a newline char must be inserted (just like when entering
appendmode) to prevent the cursor from moving to the right
Some deletion operations (especially those that use indentation)
can generate overlapping deletion ranges when using multiple cursors.
To fix that problem a new `Transaction::delete` and
`Transaction:delete_by_selection` function were added. These functions
merge overlapping deletion ranges instead of generating an invalid
transaction. This merging of changes is only possible for deletions
and not for other changes and therefore require its own function.
The function has been used in all commands that currently delete
text by using `Transaction::change_by_selection`.
