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.
Here we separate the diagnostics by severity and then overlay the Vec
of spans for each severity on top of the highlights. The error
diagnostics end up overlaid on the warning diagnostics, which are
overlaid on the hints, overlaid on info, overlaid on any other severity
(default), then overlaid on the syntax highlights.
This fixes two things:
* Error diagnostics are now always visible when overlapped with other
diagnostics.
* Ghost text is eliminated.
* Ghost text was caused by duplicate diagnostics at the EOF:
overlaps within the merged `Vec<(usize, Range<usize>)>` violate
assumptions in `helix_core::syntax::Merge`.
* When we push a new range, we check it against the last range and
merge the two if they overlap. This is safe because they both
have the same severity and therefore highlight.
The actual merge is skipped for any of these when they are empty, so
this is very fast in practice. For some data, I threw together an FPS
counter which renders as fast as possible and logs the renders per
second.
With no diagnostics, I see an FPS gain from this change from 868 FPS
to 878 (+1.1%) on a release build on a Rust file. On an Erlang file
with 12 error diagnostics and 6 warnings in view (233 errors and 66
warnings total), I see a decrease in average FPS from 795 to 790
(-0.6%) on a release build.
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.
* Implement cursorcolumn
* Add documentation
* Separate column style from line with fallback
* Fallback to cursorcolumn first
* Switch to non-fallback try_get_exact
Add new function `try_get_exact`, which doesn't perform fallback,
and use that instead because the fallback behaviour is being handled
manually.
If the close method fails, the editor will quit before restoring the
terminal. This causes the shell to break if, e.g. the LS times out
shutting down.
This fixes this by always restoring the terminal after closing, and
printing out a message to stderr if there is an error.
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].

* 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
When signature help is too large it may cause a panic when it is too
large, now I just make the hover do an intersection with surface to make
sure it never overflow.
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
* Improve keymap errors from command typos
Currently, opening helix with a config containing a bad command mapping
fails with a cryptic error. For example, say we have a config (bad.toml)
with a command name that doesn't exist:
[keys.normal]
b = "buffer_close" # should be ":buffer-close"
When we `hx -c bad.toml`, we get...
> Bad config: data did not match any variant of untagged enum KeyTrie for key `keys.normal` at line 1 column 1
> Press <ENTER> to continue with default config
This is because of the way that Serde tries to deserialize untagged
enums such as `helix_term::keymap::KeyTrie`. From the Serde docs[^1]:
> Serde will try to match the data against each variant in order and the
> first one that deserializes successfully is the one returned.
`MappableCommand::deserialize` fails (returns an Err variant) when a
command does not exist. Serde interprets this as the `KeyTrie::Leaf`
variant failing to match and declares that the input data doesn't
"match any variant of untagged enum KeyTrie."
Luckily the variants of KeyTrie are orthogonal in structure: we can tell
them apart by the type hints from a `serde:🇩🇪:Visitor`. This change
uses a custom Deserialize implementation along with a Visitor that
discerns which variant of the KeyTrie applies. With this change, the
above failure becomes:
> Bad config: No command named 'buffer_close' for key `keys.normal.b` at line 2 column 5
> Press <ENTER> to continue with default config
We also provide more explicit information about the expectations on
the field. A config with an unexpected type produces a message with
that information and the expectation:
[keys.normal]
b = 1
> Bad config: invalid type: integer `1`, expected a command, list of commands, or sub-keymap for key `keys.normal.b` at line 2 column 5
> Press <ENTER> to continue with default config
