Instead of 100 ms - 50 ms, startup takes 10 ms - 5 ms.
HighlightingAssets::get_syntax_set() is never called when e.g. piping the bat
output to a file (see Config::loop_through), so by loading the SyntaxSet only
when needed, we radically improve startup time when it is not needed.
They are just a way to get access to data embedded in the binary, so they don't
conceptually belong inside HighlightingAssets.
This has the nice side effect of getting HighlightingAssets::from_cache() and
::from_binary(), that are highly related, next to each other.
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.
Using BufReader makes sense for large files, but assets are never large enough
to require buffering. It is significantly faster to load the file contents in
one go, so let's do that instead.
Closes#1753
The syntax is named "Man Page" upstream, but our man page syntax is
different, it's for rendered man pages. Rename to Groff and remove
`.man` from extensions.
It already now reduces code duplication slightly, but will become even more
useful in the future when we add more complicated logic such as lazy-loading.
Since we only modify `pub(crate)` items, the stable bat-as-a-library API is not
affected.
This takes us one step closer to making SyntaxSet lazy-loaded, which in turn
takes us one step closer to solving #951.
This fixes a bug on Windows where `Command::new` would also run
executables from the current working directory, possibly resulting in
accidental runs of programs called `less`.
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.
