* feat: make `move_vertically` aware of tabs and wide characters
* refactor: replace unnecessary checked_sub with comparison
* refactor: leave pos_at_coords unchanged and introduce separate pos_at_visual_coords
* style: include comment to explain `pos_at_visual_coords` breaking condition
* refactor: use `pos_at_visual_coords` in `text_pos_at_screen_coords`
* feat: make `copy_selection_on_line` aware of wide characters
When a new View of a Document is created, a default cursor of 0, 0 is
created, and it does not get normalized to a single width cursor until
at least one movement of the cursor happens. This appears to have no
practical negative effect that I could find, but it makes tests difficult
to work with, since the initial selection is not what you expect it to be.
This changes the initial selection of a new View to be the width of the
first grapheme in the text.
* allows passing extra formatting options to LSPs
- adds optional field 'format' to [[language]] sections in 'languages.toml'
- passes specified options the LSPs via FormattingOptions
* cleaner conversion of formatting properties
* move formatting options inside lsp::Client
* cleans up formatting properties merge
* add reflow command
Users need to be able to hard-wrap text for many applications, including
comments in code, git commit messages, plaintext documentation, etc. It
often falls to the user to manually insert line breaks where appropriate
in order to hard-wrap text.
This commit introduces the "reflow" command (both in the TUI and core
library) to automatically hard-wrap selected text to a given number of
characters (defined by Unicode "extended grapheme clusters"). It handles
lines with a repeated prefix, such as comments ("//") and indentation.
* reflow: consider newlines to be word separators
* replace custom reflow impl with textwrap crate
* Sync reflow command docs with book
* reflow: add default max_line_len language setting

* log textobject query construction errors
The current behavior is that invalid queries are discarded silently
which makes it difficult to debug invalid textobjects (either invalid
syntax or an update may have come through that changed the valid set
of nodes).
* fix golang textobject query
`method_spec_list` used to be a named node but was removed (I think
for Helix, it was when updated to pull in the support for generics).
Instead of a named node for the list of method specs we have a bunch
of `method_spec` children nodes now. We can match on the set of them
with a `+` wildcard.
Example go for this query:
type Shape interface {
area() float64
perimeter() float64
}
Which is parsed as:
(source_file
(type_declaration
(type_spec
name: (type_identifier)
type: (interface_type
(method_spec
name: (field_identifier)
parameters: (parameter_list)
result: (type_identifier))
(method_spec
name: (field_identifier)
parameters: (parameter_list)
result: (type_identifier))))))
* Make textobject select last paragraph
Last paragraph shoud be selected if the cursor was placed on the
whitespace paragraph part and `map` is done, otherwise it would do
nothing useful, but now we select backwards for the last paragraph
which behaves similarly to kakoune, making `map` useful for the last
paragraph with whitespace. Example usecase is to copy and paste last
ledger cli paragraph quickly by `mapyp` to duplicate last entry.
* Fix typo in core textobject

This avoids costly conversions via byte_to_char (which are then
reversed back into bytes internally in Ropey).
Reduces time spent in slice/byte_to_char from ~24% to ~5%.
This is a rather large refactor that moves most of the code for
loading, fetching, and building grammars into a new helix-loader
module. This works well with the [[grammars]] syntax for
languages.toml defined earlier: we only have to depend on the types
for GrammarConfiguration in helix-loader and can leave all the
[[language]] entries for helix-core.
The vision with 'use-grammars' is to allow the long-requested feature
of being able to declare your own set of grammars that you would like.
A simple schema with only/except grammar names controls the list
of grammars that is fetched and built. It does not (yet) control which
grammars may be loaded at runtime if they already exist.
This is not strictly speaking necessary. tree_sitter_library was used by
just one grammar: llvm-mir-yaml, which uses the yaml grammar. This will
make the language more consistent, though. Each language can explicitly
say that they use Some(grammar), defaulting when None to the grammar that
has a grammar_id matching the language's language_id.
