* don't use backup files with hardlinks
* check if the inodes remain the same in the test
* move funcs to faccess and use AsRawHandle
* use a copy as a backup for hardlinks
* delete backup after copy
In the case of network file systems, if the server time is ahead
of the local system time, then helix could annoy with messages
that the file has already been modified by another application.
* replicate t-monaghan's changes
* remove View.offset in favour of Document.view_data.view_position
* improve access patterns for Document.view_data
* better borrow checker wrangling with doc_mut!()
* reintroduce ensure_cursor_in_view in handle_config_events
since we sorted out the borrow checker issues using partial borrows,
there's nothing stopping us from going back to the simpler implementation
* introduce helper functions on Document .view_offset, set_view_offset
* fix rebase breakage
Pastes are probably the last edit one means to make before the query
should run so it doesn't need to be debounced.
This makes global search much snappier for example when accepting the
history suggestion from the '/' register or pasting a pattern from the
clipboard or a register.
Two changes from the parent commit:
* Save only the `Picker::primary_query` - so you don't save other parts
of the query, for example `%path foo.rs` while in `global_search`.
* Move the saving out of the `if let Some(option) = self.selection()`
block. So when you hit enter you save to history whether you have a
selection or not. If you want to close the picker without saving to
the register you can use C-c or Esc instead.
The Prompt is set up to push the current line to history when hitting
Enter but the Picker doesn't pass the Enter event down to the Prompt
(for good reason: we don't want the Prompt's behavior of changing
completions when we hit a path separator). We should save the Prompt's
line to its configured history register when hitting Enter when there
is a selection in the Picker.
This currently only applies to `global_search`'s Picker since it's the
only Picker to use `Picker::with_history_register`.
This commit brings the text decoration API inline with the
LineAnnotation API (so they are consistent) resulting in a single
streamlined API instead of multiple ADHOK callbacks.
We can track the ranges in the input text that correspond to each column
and use this information during rendering to apply a new theme key that
makes the "active column" stand out. This makes it easier to tell at
a glance which column you're entering.
`Picker::new` loops through the input options to inject each of them, so
there's no need to collect into an intermediary Vec. This removes some
unnecessary collections. Also, pickers that start with no initial
options can now pass an empty slice instead of an empty Vec.

The `FileLocation` and `PathOrId` types can borrow paths rather than
requiring them to be owned. This takes a refactor of the preview
functions and preview internals within `Picker`. With this change we
avoid an unnecessary `PathBuf` clone per render for any picker with a
file preview function (i.e. most pickers).
This refactor is not fully complete. The `PathOrId` is _sometimes_ an
owned `PathBuf`. This is for pragmatic reasons rather than technical
ones. We need a further refactor to introduce more core types like
`Location` in order to eliminate the Cow and only use `&Path`s within
`PathOrId`. This is left for future work as it will be a larger refactor
almost entirely fitting into the LSP commands module and helix-core -
i.e. mostly unrelated to refactoring the `Picker` code itself.

This introduces a custom URI type in core meant to be extended later
if we want to support other schemes. For now it's just a wrapper over a
PathBuf. We use this new URI type to firewall `lsp::Url`. This was
previously done in 8141a4a but using a custom URI type is more flexible
and will improve the way Pickers handle paths for previews in the child
commit(s).

This fixes the changed files picker when used against a clean worktree
for example. Without it the running indicator does not disappear. It
also simplifies the dynamic query handler's implementation so that it
doesn't need to request a redraw explicitly.

We could expand on this in the future to have different preview modes
that you can toggle between with C-t. Currently that binding just hides
the preview but it could switch between different preview modes and in
one mode hide the path and just show the line contents.
The parent commit split out the workspace symbol picker to an inline
definition so the `workspace` parameter is never passed as `true`. We
should consolidate this picker definition into the symbol_picker
function.
DynamicPicker is a thin wrapper over Picker that holds some additional
state, similar to the old FilePicker type. Like with FilePicker, we want
to fold the two types together, having Picker optionally hold that
extra state.
The DynamicPicker is a little more complicated than FilePicker was
though - it holds a query callback and current query string in state and
provides some debounce for queries using the IdleTimeout event.
We can move all of that state and debounce logic into an AsyncHook
implementation, introduced here as `DynamicQueryHandler`. The hook
receives updates to the primary query and debounces those events so
that once a query has been idle for a short time (275ms) we re-run
the query.
A standard Picker created through `new` for example can be promoted into
a Dynamic picker by chaining the new `with_dynamic_query` function, very
similar to FilePicker's replacement `with_preview`.
The workspace symbol picker has been migrated to the new way of writing
dynamic pickers as an example. The child commit will promote global
search into a dynamic Picker as well.
We will use this in the child commit to improve the picker's running
indicator. Nucleo 0.4.0 includes an `active_injectors` member that we
can use to detect if anything can push to the picker. When that count
drops to zero we can remove the running indicator.
Nucleo 0.4.1 contains a fix for crashes with interactive global search
on a large directory.
This works nicely for dynamic pickers: we stop any running jobs like
global search that are pushing to the injector by incrementing the
version number when we start a new request. The boolean only allowed
us to shut the picker down once, but with a usize a picker can have
multiple "sessions" / "life-cycles" where it receives new options
from an injector.
Now that the picker is defined as a table, we need a way to provide
input for each field in the picker. We introduce a small query syntax
that supports multiple columns without being too verbose. Fields are
specified as `%field pattern`. The default column for a picker doesn't
need the `%field` prefix. The field name may be selected by a prefix
of the field, for example `%p foo.rs` rather than `%path foo.rs`.

`menu::Item` is replaced with column configurations for each picker
which control how a column is displayed and whether it is passed to
nucleo for filtering. (This is used for dynamic pickers so that we can
filter those items with the dynamic picker callback rather than nucleo.)
The picker has a new lucene-like syntax that can be used to filter the
picker only on certain criteria. If a filter is not specified, the text
in the prompt applies to the picker's configured "primary" column.
Adding column configurations for each picker is left for the child
commit.
The picker previously used the IdleTimeout event as a trigger for
syntax-highlighting the currently selected document in the preview pane.
This is a bit ad-hoc now that the event system has landed and we can
refactor towards an AsyncHook (like those used for LSP completion and
signature-help). This should resolve some odd scenarios where the
preview did not highlight because of a race between the idle timeout
and items appearing in the picker.
This fixes the modification indicator when saving from insert mode with
a config such as
[keys.insert]
C-s = ":write"
Previously the modification indicator would be stuck showing modified
even if the buffer contents matched the disk contents when writing after
some changes in insert mode with this binding. In insert mode we do not
eagerly write undo checkpoints so that all changes made become one
checkpoint as you exit insert mode. When saving, `Document`s `changes`
`ChangeSet` would be non-empty and when there are changes we show the
buffer as modified. Then switching to normal mode would append the
changes to history, bumping the current revision past what it was when
last saved. Since the last saved revision and current revision were then
unsynced, the modification indicator would always show modified.
This matches [Kakoune's behavior]. Kakoune has a different architecture
for writes but a very similar system for history, transactions and undo
checkpoints (what it calls "undo groups"). Upon saving Kakoune creates
an undo checkpoint if there are any uncommitted changes. It does this
after the write has gone through since its writing system is different.
For our writing system it's cleaner to make the undo checkpoint before
performing the save so that the history revision increments before we
send the save event.
[Kakoune's behavior]: 80fcfebca8/src/buffer.cc (L565-L566)
Previously `gf` on `~/.config/helix` for example would error if the
entire path was selected but succeed and open a picker for the directory
contents if the selection was one one-width cursor. We need to expand
tildes for all paths instead of just the auto-detected paths.
This also refactors the `goto_file` blocks a little so that we construct
`paths` once instead of creating the Vec and immediately clearing it
when the selection is one single-width cursor.
This fix allows for multiple language servers at once which support
workspace commands. This was previously broken as just the first
language server supporting workspace commands was queried when listing
allowed worspace commands.
The fix is in two parts. Firstly, querying all workspace commands from
all language servers available and using them when actually running the
command in `lsp_workspace_command`. Secondly, doing the same in
`completers::lsp_workspace_command` such that completion still works as
expected.
The fix has one remaining issue, which I am unsure how to handle in the
best way possible, but which I also don't think should happen often:
Multiple language servers may register commands with the same name. This
will lead to that command being listed in the popup menu and in the
completion list multiple times, which can be possibly confusing. One
could disambigue them in the popover menu, but I am not sure the same
can be done for completion. When running `lsp-workspace-command` with
parameters, this behavior is "fixed" by displaying an error in that
case. I am unsure if this is the best fix for this issue in that case,
but could not find a better one.
Saving while in insert mode causes issues with the modification
indicator and this is very easy to reproduce with the current state of
the auto-save hook. We can tweak the hook slightly to await the mode
switch out of insert mode to perform the save.
The debounce is preserved: if you save and then immediately exit insert
mode the debounce will be respected. If the debounce lapses while you
are in insert mode, the save occurs as you switch out of insert mode
immediately.
