We can't keep `syntect::parsing::SyntaxReference` as part of the public
API, because that might prevent us from bumping to syntect 6.0.0 without
also bumping bat to v2.0.0, once we reach v1.0.0.
So introduce a new stripped down struct `Syntax` and return that
instead. Let it be fully owned to make the API simple. It is not going
to be in a hot code path anyway.
I have looked at all code of our 27 dependents but I can't find a single
instance of this method being used, so this change should be safe for
v1.0.0.
Or rather, introduce new versions of these methods and deprecate the old ones.
This is preparation to enable robust and user-friendly support for lazy-loading.
With lazy-loading, we don't know if the SyntaxSet is valid until after we try to
use it, so wherever we try to use it, we need to return a Result. See discussion
about panics in #1747.
Otherwise Rust 1.53.0 gets confused during `cargo doc` because it thinks
we want an actual URL:
warning: this URL is not a hyperlink
--> src/pretty_printer.rs:331:40
|
331 | /// The title for the input (e.g. "http://example.com/example.txt")
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: use an automatic link instead: `<http://example.com/example.txt>`
|
= note: `#[warn(rustdoc::bare_urls)]` on by default
= note: bare URLs are not automatically turned into clickable links
It was perhaps also a bit confusing to give an URL as an example in the
first place, because according to our own API example
`examples/inputs.rs` it is meant to be more a free-text thing.
This adds a new `--diff` option that can be used to only show lines
close to Git changes (added/removed/modified lines). The amount of
additional context can be controlled with `--diff-context=N`.
