* 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.

The new version of the `toml` crate is based on `toml_edit` and does
not support zero copy deserialization anymore. So we need to deserialize
`String` instead of `&str` in the keympa
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.
After changes in #5239, the loaded configuration wasn't stored,
resulting in a success message even if the instance kept the previous
configuration values.
Commit 1b89d3e535 introduced a regression
where opening a new file would no longer work, because attempting to
canonicalize its path would lead to a "No such file or directory"
error. Fall back to opening a new file when encountering an error to
fix this case.
This commit addresses issue 5193, where the author
requested that the name of the binary needed is printed along
with the rest of the health information.
This commit adds a format! macro which formats in the name of the
binary and then it will be printed along with the rest of the
debug information. The value in cmd is referenced to the call
to which, and then consumed upon the call to format!
This roughly matches the behavior of the diagnostic picker: when
jumping to a diagnostic with `[d`/`]d`/`[D`/`]D`, the range of the
diagnostic is selected instead of the start point.
A language server might send None as the response to workspace symbols.
We should treat this as the empty Vec rather than the server sending
an error status. This fixes the interaction with gopls which uses
None to mean no matching symbols.
If the new results shown by the picker select a file that hasn't been
previewed before, the idle timeout would not trigger highlighting on
that file. With this change, we reset the idle timeout and allow that
file to be highlighted on the next idle timeout event.
This change uses the idle-timeout event to trigger fetching new results
in the DynamicPicker, so idle-timeout becomes a sort of debounce. This
prevents querying the language server overly aggressively.
