* 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
* add basic completion replay
* use transaction as the last completion
* completion replay only on trigger position
* cache changes in CompletionAction

* 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

* Refactor file picker filetype filter logic to remove panic, make clearer
An unwrap was unneccesarily present due to a prior contribution of mine
which was before I had any understanding of error handling in Rust. I've
also swapped a match for an if let, as was originally suggested in the
original pull request adding filetype filtering, but was merged before I
could address.
* Add some comments to the file picker code for clarity
* Switch to expect instead of ignoring type def error
* ignore Enter keypress when menu has no selection
supersedes #1622
Builds on the work in #1285. I want to allow Enter to create a newline
when there is no selection in the autocomplete menu.
This occurs somewhat often when using LSP autocomplete in Elixir which
uses `do/end` blocks (and I set the autocomplete menu delay to 0 which
exacerbates the problem):
```elixir
defmodule MyModule do
def do_foo(x) do
x
end
def other_function(y) do|
end
```
Here the cursor is `|` in insert mode. The LSP suggests `do_foo` but I
want to create a newline. Hitting Enter currently closes the menu,
so I end up having to hit Enter twice when the module contains any
local with a `do` prefix, which can be inconsistent. With this change,
we ignore the Enter keypress to end up creating the newline in this case.
* pop compositor layer when ignoring Enter keypress
* move closing function out of consumed event result closure
* explicitly label close_fn as an 'Option<Callback>'
* 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.
* rename AutoPair -> Pair
* clean up insert_char command
* remove Rc
* remove some explicit cloning with another impl
* fix lint
* review comments
* global auto-pairs = false takes precedence over language settings
* make clippy happy
* print out editor config on startup
* move auto pairs accessor into Document
* rearrange auto pair doc comment
* use pattern in Froms
* Add Event::Used to use event callback without consuming
* Close popup if contents ignored event
* collect event results before executing callbacks
* don't add new result variant, use Ignored(..) instead
* break in match cases
* Make auto_close configurable
* fix merge
* auto close hover popups
* fix formatting
Some users (including myself) want to turn off filtering of files
prefixed with `.`, as they are often useful to edit. For example, `.env`
files, configuration for linters `.eslint.json` and the like.
The unwrap (or '.ok()' rather) triggers for some errors but not
negative status codes. In the case where helix is being packaged
in an empty git repository, the existing mechanism will fail because
git init
git rev-parse HEAD
gives a negative exit code and prints to stderr
stderr: "fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree....
with a stdout of "HEAD\n" (too short to slice with [..8]).
* feat(commands): command palette
Add new command to display command pallete that can be used
to discover and execute available commands.
Fixes: https://github.com/helix-editor/helix/issues/559
* Make picker take the whole context, not just editor
* Bind command pallete
* Typable commands also in the palette
* Show key bindings for commands
* Fix tests, small refactor
* Refactor keymap mapping, fix typo
* Ignore sequence key bindings for now
* Apply suggestions
* Fix lint issues in tests
* Fix after rebase

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).
If building from source and the source is contained in a larger
repository, we'd contain the wrong version. It's also easy to
accidentally have a newer tag that would change the version.
This code:
let start = ensure_grapheme_boundary_next(text, text.byte_to_char(start));
let end = ensure_grapheme_boundary_next(text, text.byte_to_char(end));
Would convert byte to char index, but then internally immediately convert back
to byte index, operate on it, then convert it to char index.
This change reduces the amount of time spent in ensure_grapheme_boundary from
29% to 2%.

* 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`.
