The loop always iterates the number of times the user specified even
if the beginning/end of the document is reached.
For an extreme demonstration try the following commands, Helix will
hang for several seconds.
100000000w
100000000]c
If the last argument to shellwords ends in a multibyte utf8 character
the entire argument will be dropped.
e.g. `:sh echo test1 test2𒀀` will only output `test1`
Add additional tests based on the code review feedback
The purpose of this change is to remove the mutable self borrow on
`HighlightIterLayer::sort_key` so that we can sort layers with the
correct ordering using the `Vec::sort` function family.
`HighlightIterLayer::sort_key` needs `&mut self` since it calls
`Peekable::peek` which needs `&mut self`. `Vec::sort` functions
only give immutable borrows of the elements to ensure the
correctness of the sort.
We could instead approach this by creating an eager Peekable and using
that instead of `std::iter::Peekable` to wrap `QueryCaptures`:
```rust
struct EagerPeekable<I: Iterator> {
iter: I,
peeked: Option<I::Item>,
}
impl<I: Iterator> EagerPeekable<I> {
fn new(mut iter: I) -> Self {
let peeked = iter.next();
Self { iter, peeked }
}
fn peek(&self) -> Option<&I::Item> {
self.peeked.as_ref()
}
}
impl<I: Iterator> Iterator for EagerPeekable<I> {
type Item = I::Item;
fn next(&mut self) -> Option<Self::Item> {
std::mem::replace(&mut self.peeked, self.iter.next())
}
}
```
This would be a cleaner approach (notice how `EagerPeekable::peek`
takes `&self` rather than `&mut self`), however this doesn't work in
practice because the Items emitted by the `tree_sitter::QueryCaptures`
Iterator must be consumed before the next Item is returned.
`Iterator::next` on `tree_sitter::QueryCaptures` modifies the
`QueryMatch` returned by the last call of `next`. This behavior is
not currently reflected in the lifetimes/structure of `QueryCaptures`.
This fixes an issue with layers being out of order when using combined
injections since the old code only checked the first range in the
layer. Layers being out of order could cause missing highlights for
combined-injections content.
* 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.

increment/decrement (C-a/C-x) had some buggy behavior where selections
could be offset incorrectly or the editor could panic with some edits
that changed the number of characters in a number or date. These stemmed
from the automatic jumping behavior which attempted to find the next
date or integer to increment. The jumping behavior also complicated the
code quite a bit and made the behavior somewhat difficult to predict
when using many cursors.
This change removes the automatic jumping behavior and only increments
or decrements when the full text in a range of a selection is a number
or date. This simplifies the code and fixes the panics and buggy
behaviors from changing the number of characters.
* Add a undo/redo split test case for crossing branches
* history: Switch up/down transaction chaining order
The old code tends to work in practice because, usually, either up_txns
or down_txns are empty. When both have contents though, we can run into
a panic trying to compose them all since they will disagree on the
length of the text. This fixes the panic test case in the parent
commit.

The 'revisions' field on History can't be treated as linear: each
Revision in the revisions Vec has a parent link and an optional child
link. We can follow those to unroll the recent history.
When using undo/redo, the history revision can be decremented. In that
case we should apply the inversions since the given revision in
History::changes_since. This prevents panics with jumplist operations
when a session uses undo/redo to move the jumplist selection outside
of the document.
* Add a test case for updating jumplists across windows
* Apply transactions to all views on history changes
This ensures that jumplist selections follow changes in documents, even
when there are multiple views (for example a split where both windows
edit the same document).
* Leave TODOs for cleaning up View::apply
* Use Iterator::reduce to compose history transactions

The current `:tree-sitter-subtree` has a bug for field-names when the
field name belongs to an unnamed child node. Take this ruby example:
def self.method_name
true
end
The subtree given by tree-sitter-cli is:
(singleton_method [2, 0] - [4, 3]
object: (self [2, 4] - [2, 8])
name: (identifier [2, 9] - [2, 20])
body: (body_statement [3, 2] - [3, 6]
(true [3, 2] - [3, 6])))
But the `:tree-sitter-subtree` output was
(singleton_method
object: (self)
body: (identifier)
(body_statement (true)))
The `singleton_method` rule defines the `name` and `body` fields in an
unnamed helper rule `_method_rest` and the old implementation of
`pretty_print_tree_impl` would pass the `field_name` down from the
named `singleton_method` node.
To fix it we switch to the [TreeCursor] API which is recommended by
the tree-sitter docs for traversing the tree. `TreeCursor::field_name`
accurately determines the field name for the current cursor position
even when the node is unnamed.
[TreeCursor]: https://docs.rs/tree-sitter/0.20.9/tree_sitter/struct.TreeCursor.html
This fixes an edge case for completing shellwords. With a file
"a b.txt" in the current directory, the sequence `:open a\<tab>`
will result in the prompt containing `:open aa\ b.txt`. This is
because the length of the input which is trimmed when replacing with
completion is calculated on the part of the input which is parsed by
shellwords and then escaped (in a separate operation), which is lossy.
In this case it loses the trailing backslash.
The fix provided here refactors shellwords to track both the _words_
(shellwords with quotes and escapes resolved) and the _parts_ (chunks
of the input which turned into each word, with separating whitespace
removed). When calculating how much of the input to delete when
replacing with the completion item, we now use the length of the last
part.
This also allows us to eliminate the duplicate work done in the
`ends_with_whitespace` check.
* add tree sitter match limit to avoid slowdowns for larger files
Affects all tree sitter queries and should speedup both
syntax highlighting and text object queries.

for rust files as small as 3k loc.

`deepest_preceding` is known to be a descendant of `node`. Repeated
calls of `Node::parent` _should_ eventually turn `deepest_preceding`
into `node`, but when the node is errored (the tree contains a syntax
error), `Node::parent` returns None.
In the typescript case:
if(true) &&true
// ^ press enter here
The tree is:
(program [0, 0] - [1, 0]
(if_statement [0, 0] - [0, 15]
condition: (parenthesized_expression [0, 2] - [0, 8]
(true [0, 3] - [0, 7]))
consequence: (expression_statement [0, 8] - [0, 15]
(binary_expression [0, 8] - [0, 15]
left: (identifier [0, 8] - [0, 8])
right: (true [0, 11] - [0, 15])))))
`node` is the `program` node and `deepest_preceding` is the
`binary_expression`. The tree is errored on the `binary_expression`
node with `(MISSING identifier [0, 8] - [0, 8])`.
In the C++ case:
; <<
// press enter after the ';'
The tree is:
(translation_unit [0, 0] - [1, 0]
(expression_statement [0, 0] - [0, 1])
(ERROR [0, 1] - [0, 4]
(identifier [0, 1] - [0, 1])))
`node` is the `translation_unit` and `deepest_preceding` is the `ERROR`
node.
In both cases, `Node::parent` on the errored node returns None.
This changes the completion items to be rendered with shellword
escaping, so a file `a b.txt` is rendered as `a\ b.txt` which matches
how it should be inputted.
8584b38cfb switched to shellwords for
completion in command-mode. This changes the conditions for choosing
whether to complete the command or use the command's completer.
This change processes the input as shellwords up-front and uses
shellword logic about whitespace to determine whether the command
or argument should be completed.
The change in d801a6693c to search for
suffixes in `file-types` is too permissive: files like the tutor or
`*.txt` files are now mistakenly interpreted as R or perl,
respectively.
This change changes the syntax for specifying a file-types entry that
matches by suffix:
```toml
file-types = [{ suffix = ".git/config" }]
```
And changes the file-type detection to first search for any non-suffix
patterns and then search for suffixes only with the file-types entries
marked explicitly as suffixes.
Just like for grammars we currently force a lower-case of the name for
some actions (like filesystem lookup). To make this consistent and less
surprising for users, we remove this lower-casing here.
Note: it is still the preferred way to name both language and grammar in
lower-case

* Fix shellwords delimiter handling
This allows commands such as `:set statusline.center ["file-type"]` to
work. Before the quotes within the list would mess it up.
Also added a test to ensure correct behavior
* Rename Delimiter -> OnWhitespace
* 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.

Info logs don't show up in the log file by default, but this line
should: failures to load tree-sitter parser objects are useful errors.
A parser might fail to load it is misconfigured
(https://github.com/helix-editor/helix/pull/4303#discussion_r996448543)
or if the file does not exist.
This changes the behavior of operations like `]f`/`[f` to set the
direction of the new range to the direction of the action.
The original behavior was to always use the head of the next function.
This is inconsistent with the behavior of goto_next_paragraph and makes
it impossible to create extend variants of the textobject motions.
This causes a behavior change when there are nested functions. The
behavior in the parent commit is that repeated uses of `]f` will
select every function in the file even if nested. With this commit,
functions are skipped.
It's notable that it's possible to emulate the original behavior by
using the `ensure_selections_forward` (A-:) command between invocations
of `]f`.
* Split helix_core::find_root and helix_loader::find_local_config_dirs
The documentation of find_root described the following priority for
detecting a project root:
- Top-most folder containing a root marker in current git repository
- Git repository root if no marker detected
- Top-most folder containing a root marker if not git repository detected
- Current working directory as fallback
The commit contained in https://github.com/helix-editor/helix/pull/1249
extracted and changed the implementation of find_root in find_root_impl,
actually reversing its result order (since that is the order that made
sense for the local configuration merge, from innermost to outermost
ancestors).
Since the two uses of find_root_impl have different requirements (and
it's not a matter of reversing the order of results since, e.g., the top
repository dir should be used by find_root only if there's not marker in
other dirs), this PR splits the two implementations in two different
specialized functions.
In doing so, find_root_impl is removed and the implementation is moved
back in find_root, moving it closer to the documented behaviour thus
making it easier to verify it's actually correct
* helix-core: remove Option from find_root return type
It always returns some result, so Option is not needed
* Update description of `m` textobject to its actual functionality
Sometime recently the functionality of `m` was changed to match the
nearest pair to the cursor, rather than the former functionality of
matching the pair only if the cursor was on one of the brace characters
directly.
* Rename surround methods to reflect that they work on pairs
The current naming suggests that they may work generally on any
textobject, whereas their implementation really focuses on pairs.
* Change description of m textobject to match actual functionality
The current implementation of `m` no longer merely looks at the pair
character the cursor is on, but actually will search for the pair
(defined in helix-core/src/surround.rs) that encloses the cursor, and
not the entire selection.

* 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

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
