Fix clippy lints (#6454) 2 years ago
Pascal Kuthe 2af14a24ab respect line annotations in char_idx_at_visual_row_offset
char_idx_at_visual_row_offset asssumed that a single line/block break
always corresponded to a vertical offset of 1. However conceal can hide
the line break (in which case the certical offset would be 0) and line
annotations (or softwrapped inlay hints at the end of the line) can insert
addtional vertical lines.

To correctly account for these cases we simply compute the visual offset
of the start of the next block from the previous block instead of the
visual offset of the block end. This means that the line breaks at the
end of the block (however many there may be) are automatically included
and we don't need to manually add 1 to the `row_offset` anymore.

Pascal Kuthe 7cf448eb5b use partition_point instead of binary_search_by
Using `partition_point` ensures we always find the first entry.
With binary search it is "random" (deterministic but implementation
specific) which index is retruned if there are multiple equal elements.
`partition_point` was added to the standard library to cover extactly
the usecase here.

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.

Skyler Hawthorne d3b051d28e fix test::plain

2 years ago
Skyler Hawthorne 58ea193054 Allow explicit newlines in test DSL
The current test DSL currently has no way to express being at the end of
a line, save for putting an explicit LF or CRLF inside the `#[|]#`. The
problem with this approach is that it can add unintended extra new lines
if used in conjunction with raw strings, which insert newlines for you.

This is a simple attempt to mitigate this problem. If there is an
explicit newline character at the end of the selection, and then it
is immediately followed by the same newline character at the right end
of the selection, this following newline is removed. This way, one can
express a cursor at the end of a line explicitly.

Pascal Kuthe 2b64a64d7e Add API to create a Transaction from potentially overlapping changes
This commit adds new functions to `Transaction` that allow creating
edits that might potentially overlap. Any change that overlaps
previous changes is ignored. Furthermore, a utility method is added
that also drops selections associated with dropped changes (for
transactions that are created from a selection).

This is needed to avoid crashes when applying multicursor
autocompletions, as the edit from a previous cursor may overlap
with the next cursor/edit.

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

Make `m` textobject look for pairs enclosing selections (#3344)
* Make `m` textobject look for pairs enclosing selections

Fix initial highlight layer sort order (#5196)
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 and enable softwrap/virtual text (#5420)
* 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.

Separate jump behavior from increment/decrement (#4123)
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.

Use TreeCursor to pretty-print :tree-sitter-subtree (#4606)
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.

Capture word parts while calculating shellwords (#4632)
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.

`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.

8584b38cfb switched to shellwords for

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

Change syntax for suffix file-types configurations (#4414)
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

surprising for users, we remove this lower-casing here.

Note: it is still the preferred way to name both language and grammar in

Fix multi byte auto pairs (#4024)
* 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

Michael Davis 274f2ea459 Use requested direction for new textobject selection range
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 (#3929)
* 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

Adjust `m` textobject description and minor code clarification (#3343)
* 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.

When a new View of a Document is created, a default cursor of 0, 0 is

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.

* 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.

* Sync reflow command docs with book

Fix Golang textobject queries (#2153)
* 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))

Reduces time spent in slice/byte_to_char from ~24% to ~5%.

Michael Davis 7044d7d804 rename '--fetch/build-grammars' flags into '--grammar fetch/build'
The old flags were a bit long. --grammar is also aliased to -g to make
it even easier.

Michael Davis 4fc991fdec migrate grammar fetching/building code into helix-loader crate
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.

Michael Davis 08ee949dcb add 'use-grammars' to languages.toml
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.
