This was not distinguishing the error types when trying a receive on an empty
receiver, which was erroneously causing the sender to be closed when trying to
flush the writes when there were none
If a document is written with a new path, currently, in the event that
the write fails, the document still gets its path changed. This fixes
it so that the path is not updated unless the write succeeds.
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.
Applying a transaction to a View adjusts the ranges in the jumplist
to ensure that they remain within the text of the document and follow
regular selection invariants (for example, must be have a width of at
least one).
* 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.
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`).
* Change focus to modified docs on quit
When quitting with modified documents, automatically switch focus to
one of them.

* Add RawTheme to handle inheritance with theme palette
* Add a intermediate step in theme loading
it uses RawTheme struct to load the original ThemePalette, so we can merge it with the inherited one.
* Load default themes via RawThemes, remove Theme deserialization
* Allow naming custom theme same as inherited one
* Remove RawTheme and use toml::Value directly
* Resolve all review changes resulting in a cleaner code
* Simplify return for Loader::load
* Add implementation to avoid extra step for loading of base themes
Underline styles are mutally exclusive and overwrite each other.
Therefore implementing as an modifier lead to incorrect behaviour
when the underline style is overwritten.
For backwards compatability the "underline" modified is retained (but
deprecated). Instead the "underline_style" and "underline_color"
optios should be used to style underlines.
Applying document-change transactions to diagnostic ranges is not stable
with respect to the ordering of diagnostics. This can cause diagnostics
to become temporarily unordered with some edits to a document, which can
eventually break some invariants/assumptions in syntax::merge.
With this change, Document::diagnostics are always sorted.
Currently it is not possible to save a file with a language that
has an external formatter configuration unless the external
formatter is installed, even if the language has a Language Server
configuration capable of auto-format. This change checks that the
external formatter exists before using it to create a formatting
callback.
* Derive Document language name from `languages.toml` `name` key
This changes switches from deriving the language name from the
`languages.toml` `scope` key to `name` (`language_id` in the
`LanguageConfiguration` type). For the most part it works to derive the
language name from scope by chopping off `source.` or `rsplit_once` on
`.` but for some languages we have now like html (`text.html.basic`),
it doesn't. This also should be a more accurate fallback for the
`language_id` method which is used in LSP and currently uses the
`rsplit_once` strategy.
Here we expose the language's name as `language_name` on `Document` and
replace ad-hoc calculations of the language name with the new method.
This is most impactful for the `file-type` statusline element which is
using `language_id`.
* Use `Document::language_name` for the `file-type` statusline element
The `file-type` indicator element in the statusline was using
`Document::language_id` which is meant to be used to for telling
Language Servers what language we're using. That works for languages
with `language-server` configurations in `languages.toml` but shows
text otherwise. The new `Document::language_name` method from the
parent commit is a more accurate way to determine the language.
Ported over from 61365dfbf3 in the `gui` branch. This will allow
adding our own events, most notably an idle timer event (useful
for adding debounced input in [dynamic pickers][1] used by interactive
global search and workspace symbols).
