When backward-deleting a character, if this character and the following
character form a Pair, we want to delete both. However, there is a bug
that deletes both characters also if both characters are closers of some
Pair.
This commit fixes that by adding an additional check that the deleted
character should be an opener in a Pair.
Closes https://github.com/helix-editor/helix/issues/4544.
This bug occurs on `shell_insert_output` and `shell_append_output`
commands.
The previous implementation would create a child process using the Rust
stdlib's `Command` builder. However, when nothing should be piped in
from the editor, the default value for `stdin` would be used. According
to the Rust stdlib documentation that is `Stdio::inherit` which will
make the child process inherit the parent process' stdin. This would
cause the terminal to freeze.
This change will set the child process' stdin to `Stdio::null` whenever
it doesn't pipe it. In the `if` statement where this change was made
there was an extra condition for windows that I am not sure if would
require some special treatment.
This complicates the code a little but it often divides by two the number of allocations done by
the functions. LSP labels especially can easily be called dozens of time in a single menu popup,
when listing references for example.
When we do auto formatting, the code that takes the LSP's response and applies
the changes to the document are just getting the currently focused view and
giving that to the function, basically always assuming that the document that
we're applying the change to is in focus, and not in a background view.
This is usually fine for a single view, even if it's a buffer in the
background, because it's still the same view and the selection will get updated
accordingly for when you switch back to it. But it's obviously a problem for
when there are multiple views, because if you don't have the target document in
focus, it will ask the document to update the wrong view, hence the crash.
The problem with this is picking which view to apply any selection change to.
In the absence of any more data points on the views themselves, we simply pick
the first view associated with the document we are saving.
The way that document writes are handled are by submitting them to the
async job pool, which are all executed opportunistically out of order. It
was discovered that this can lead to write inconsistencies when there
are multiple writes to the same file in quick succession.
This seeks to fix this problem by removing document writes from the
general pool of jobs and into its own specialized event. Now when a
user submits a write with one of the write commands, a request is simply
queued up in a new mpsc channel that each Document makes to handle its own
writes. This way, if multiple writes are submitted on the same document,
they are executed in order, while still allowing concurrent writes for
different documents.
Undo/redo/earlier/later call `Document::apply_impl` which applies
transactions to the document. These transactions also need to be
applied to the view as in 0aedef0.
It is easy to forget to call `Document::apply` and/or `View::apply` in
the correct order. This commit introduces a helper function which
closes over both calls.
This change adds View::apply calls for all Document::apply call-sites,
ensuring that changes to a document do not leave invalid entries in
the View's jumplist.
This change automatically tracks pending text for for commands which use
on-next-key callbacks. For example, `t` will await the next key event
and "t" will be shown in the bottom right-hand corner to show that we're
in a pending state.
Previously, the text for these on-next-key commands needed to be
hard-coded into the command definition which had some drawbacks:
* It was easy to forget to write and clear the pending text.
* If a command was remapped in a custom config, the pending text would
still show the old key.
With this change, pending text is automatically tracked based on the
key events that lead to the command being executed. This works even
when the command is remapped in config and when the on-next-key
callback is nested under some key sequence (for example `mi`).
* keymap: Rename A "Insert at end of line"
The language for the `A` binding is potentially confusing because
`A` behaves like `i` done at the end of the line rather than `a`.
This change renames the command to match Kakoune's language[^1].
[^1]: 021da117cf/src/normal.cc (L2229)
* keymap: Rename I `insert_at_line_start`
* Select inserted space after join
* Split join_selections with space selection to A-J
Kakoune does that too and some users may still want to retain their selections.
* Update join_selections docs
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
`extend_line_above` (and `extend_line` when facing backwards) skip
a line when the current range does not fully cover a line.
Before this change:
foo
b#[|a]#r
baz
With `extend_line_above` or `extend_line` selected the line above.
#[|foo
bar]#
baz
Which is inconsistent with `extend_line_below`. This commit changes
the behavior to select the current line when it is not already
selected.
foo
#[|bar]#
baz
Then further calls of `extend_line_above` extend the selection up
line-wise.
This refactor changes the overall structure of the goto_ts_object_impl
command without removing any functionality from its behavior. The
refactored motion:
* acts on all selections instead of reducing to one selection
* may be repeated with the `repeat_last_motion` (A-.) command
* informs the user when the syntax-tree is not accessible in the current buffer
This change adds documents to the view's document history Vec.
(This is used by `ga` for example to access the last buffer.)
Previously, a sequence like so would have confusing behavior:
1. Open file A: any document with an active language server
2. Find some definition that lives in another file - file B - with `gd`
3. Jump back in the jumplist with `C-o` to file A
4. Use `ga` intending to switch back to file B
The behavior prior to this change was that `ga` would switch to file
A: you could not use `ga` to switch to file B.
* let extend-line respect range direction
* fix extend above logic
* keep `x` existing binding
* Update book/src/keymap.md

* 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.

This opens the way for merging the menu and picker code in the

excitingly, this change will also allow aligning items in the
picker, which would be useful (for example) in the command palette
for aligning the descriptions to the left and the keybinds to
the right in two separate columns.
The item formatting of each picker has been kept as is, even though
there is room for improvement now that we can format the data into
columns, since that is better tackled in a separate PR.

This reverts commit 764d14f55894dc7213e48022dfa0f91829b8ef59.
The command palette previously used + as a delimiter for denoting
a single key in a key sequence, (like C+w). This was at odds with
how the statusline displayed them with pending keys (like <C-w>).
This patch changes the palette formatting to the statusline formatting
* 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.
In certain circumstances it was possible to get into an infinite loop
when replaying macros such as when different macros attempt to replay
each other.
This commit adds changes to track which macros are currently being
replayed and prevent getting into infinite loops.

Change the layout of existing split view from horizontal to vertical and
vica-versa. It only effects the focused view and its siblings, i.e. not
recursive.
Command is mapped to 't' or 'C-t' under the Window menus.
Currently ctrl-w in insert mode deletes the cursor which results in
unexpected behavior. The patch also reduces the selection to cursor before
performing prev word to remove the behavior of removing unnecessary text
when nothing should be removed.
1. `::#(|)#::` after `ctrl-w` should be `#(|)#::`, previously `#(|)#:`
2. `#(|::)#` after `ctrl-w` should be `#(|::)#`, previously `#(|)#`
Fix#2390
Inserting a newline currently collapses any connected selections when inserting
or appending. It's happening because we're reducing the selections down to
their cursors (`let selection = ..` line) and then computing the new selection
based on the cursor. We're discarding the original head and anchor information
which are necessary to emulate Kakoune's behavior.
In Kakoune, inserting a newline retains the existing selection and _slides_
it (moves head and anchor by the same amount) forward by the newline and
indentation amount. Appending a newline extends the selection to include the
newline and any new indentation.
With the implementation of insert_newline here, we slide by adding the global
and local offsets to both head and anchor. We extend by adding the global
offset to both head and anchor but the local offset only to the head.
* feat(commands): better handling of buffer-close
Previously, when closing buffer, you would loose cursor position in other docs.
Also, all splits where the buffer was open would be closed.
This PR changes the behavior, if the view has also other buffer
previously viewed it switches back to the last one instead of the view
being closed. As a side effect, since the views are persisted,
the cursor history is persisted as well.
Fixes: https://github.com/helix-editor/helix/issues/1186
* Adjust buffer close behavior
* Remove closed documents from jump history
* Fix after rebase
* Fix ctrl-u on insert behavior
Now should follow vim behavior more
- no longer remove text on cursor
- no longer remove selected text while inserting
- first kill to start non-whitespace, start, previous new line
* Add comment for c-u parts
Select multiple line and open should be based on the whole selection
and not just the line of the cursor, which causes weird behavior like
opening in the middle of the selection which user might not expect.
* added command to extend selection to line above
* fixed view not scrolling up when reaching top of the screen
* refactored shared code into separate impl
The `file_picker_at_current_directory` command opens the file picker at
the current working directory (CWD). This can be useful when paired with
the built-in `:cd` command which changes the CWD.
It has been mapped to `space F` by default.
The search implementation would start searching at the next grapheme
boundary after the previous selection. In case the next occurence of the
needle is immediately after the current selection, this occurence would
not be found (without wraparound) because the first grapheme is skipped.
The correct approach is to use the ensure_grapheme_boundary functions instead
of using the functions that skip unconditionally to the next grapheme.

Currently match is finding the match based on the anchor rather than the
head (cursor) so this behavior is rather unexpected when user is doing
a match but a different item was matched instead when the selection is
more than one character.
* Fix bug with auto replacing components in compositor
This was last known to be working with 5995568c at the
time of commit, but now doesn't work with latest rust
stable.
The issue probably stems from using
std::any::type_name() for finding a component in the
compositor, for which the docs explicitly warn against
considering it as a unique identifier for types.
`replace_or_push()` takes a boxed `Component` and
passes it to `find_id()` which compares this with a
bare Component. `type_name()` returns `Box<T>` for
the former and `T` for latter and we have a false
negative. This has been solved by using a generics
instead of trait objects to pass in a `T: Component`
and then use it for comparison.
I'm not exactly sure how this worked fine at the
time of commit of 5995568c; maybe the internal
implementation of `type_name()` changed to properly
indicate indirection with Box.
* Do not compare by type name in compositor find_id
* Implement buffer-close-all
* Implement buffer-close-others
* Refactor all buffer close variants to use shared logic
* Fix clippy lint
* Docgen for new commands
* Shorten error message for attempting to close buffers that don't exist
* Refactor shared buffer methods to pass only editor, not whole compositor
* Switch signature of bulk buffer closing to use slice of DocumentIds
Addresses feedback that accepting an IntoIterator implementor is too
much for an internal. Also possibly saves some moving?
* Show infobox to hint textobjects with `mi` and `ma`
* Add note to infobox than any pair of characters will work too
The wording could probably be a little more clear, but I wanted to
keep it short but still accurate.
* Don't allocate a vec for the static help text
* Fix bug where `mi<esc>` would swallow next input and persist infobox
* Better help text for arbitrary pair matching in textobject selection
* Add way to add fake pending key data below status, use with `mi`/`ma`
This is a bit hacky as it makes use of global state which will end
up managed in multiple places, but has precedent in the way autoinfo
works. There should probably be a bigger refactor to handle this
kind of state better.
* Return early on anything other than `mi` and `ma` for autoinfo
* Remove "ascii" from help text with `mi` and `ma`
* Update helix-term/src/ui/editor.rs

* impl auto pairs config
Implements configuration for which pairs of tokens get auto completed.
In order to help with this, the logic for when *not* to auto complete
has been generalized from a specific hardcoded list of characters to
simply testing if the next/prev char is alphanumeric.
It is possible to configure a global list of pairs as well as at the
language level. The language config will take precedence over the
global config.

In order to implement this completer, the completion function needs to
be able to access the compositor's context (to allow it to get the
list of buffers currently open in the context's editor).
* add select_next_sibling and select_prev_sibling commands
* refactor objects to use higher order functions
* address clippy feedback
* move selection cloning into commands
* add default keybindings under left/right brackets
* use [+t,]+t for selecting sibling syntax nodes
* setup Alt-{j,k,h,l} default keymaps for syntax selection commands
* reduce boilerplate of select_next/prev_sibling in commands
* import tree-sitter Node type in commands
* add show_subtree command for viewing tree-sitter subtree in Popup
* remove '.slice(..)' from show_subtree command
* name docs and subtree Popups 'hover'
* feat(commands): shrink_selection
Add `shrink_selection` command that can be used to shrink
previously expanded selection.
To make `shrink_selection` work it was necessary to add
selection history to the Document since we want to shrink
the selection towards the syntax tree node that was initially
selected.
Selection history is cleared any time the user changes
selection other way than by `expand_selection`. This ensures
that we don't get some funky edge cases when user calls
`shrink_selection`.
