Softwrapping improvements (#5893)
* use max_line_width + 1 during softwrap to account for newline char

Helix softwrap implementation always wraps lines so that the newline
character doesn't get cut off so he line wraps one chars earlier then
in other editors. This is necessary, because newline chars are always
selecatble in helix and must never be hidden.

However That means that `max_line_width` currently wraps one char
earlier than expected. The typical definition of line width does not
include the newline character and other helix commands like `:reflow`
also don't count the newline character here.

This commit makes softwrap use `max_line_width + 1` instead of
`max_line_width` to correct the impedance missmatch.

* fix typos

Co-authored-by: Jonathan Lebon <jonathan@jlebon.com>

* Add text-width to config.toml

* text-width: update setting documentation

* rename leftover config item

* remove leftover max-line-length occurrences

* Make `text-width` optional in editor config

When it was only used for `:reflow` it made sense to have a default
value set to `80`, but now that soft-wrapping uses this setting, keeping
a default set to `80` would make soft-wrapping behave more aggressively.

* Allow softwrapping to ignore `text-width`

Softwrapping wraps by default to the viewport width or a configured
`text-width` (whichever's smaller). In some cases we only want to set
`text-width` to use for hard-wrapping and let longer lines flow if they
have enough space. This setting allows that.

* Revert "Make `text-width` optional in editor config"

This reverts commit b247d526d6.

* soft-wrap: allow per-language overrides

* Update book/src/configuration.md

rework positioning/rendering and enable softwrap/virtual text (#5420)
* 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.

Skyler Hawthorne d706194597 chore(write): serialize write operations within a Document
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.

Re-sort diagnostics after transaction transform (#3895)
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.

Look for the external formatter before invoking it (#3670)
Currently it is not possible to save a file with a language that

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 (#3338)
* 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.

Indent with tabs by default (#3095) 2 years ago
Skyler Hawthorne 0f3c10a021 Fix initial selection of Document in new view
When a new View of a Document is created, a default cursor of 0, 0 is
created, and it does not get normalized to a single width cursor until
at least one movement of the cursor happens. This appears to have no
practical negative effect that I could find, but it makes tests difficult
to work with, since the initial selection is not what you expect it to be.

This changes the initial selection of a new View to be the width of the
first grapheme in the text.

Implements configuration for which pairs of tokens get auto completed.

In order to help with this, the logic for when *not* to auto complete

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.
