This simplifies the `print_line` function a little bit while also
providing a way for syntax highlighting to be skipped when it's
not being used (i.e. `--color=never`).
This commit strips OSC (Operating System Command) sequences before
printing lines. Eventually when time permits, I want to add back
support for printing OSC sequences (and improve it to treat hyperlinks
like an attribute).
Until then, this should help prevent garbled output :)
This reverts commit 8174e02279. Turns out
it is needed for a common use case, see
https://github.com/sharkdp/bat/issues/2307.
It is not a clean revert, because I adjust CHANGELOG.md and also add a
comment to the test. I also had to resolve a small `use` conflict.
* Strip BOM from output in interactive mode
* Strip BOM when not loop_through, add regression tests
* Update CHANGELOG.md
* Only strip BOM from beginning of first line
* Fix integration test on macOS that relied on color scheme
* Fix integration test on Windows that relied on detected terminal width
* Fix syntax test that was failing due to a previously wrong (now fixed) highlighting

We do this to only have one invocation of `highlighter.highlight(...)`
so we don't need to change to `highlighter.highlight_line(...)` in two
places in #2181.
By forwarding the task to find the `Plain Text` syntax to `assets`. Not only does
the code become simpler; we also get rid of a call to `self.get_syntax_set()`
which is beneficial to the long term goal of replacing `syntaxes.bin` with
`minimal_syntaxes.bin`.
Note that the use of `.expect()` is not a regression in error handling. It was
previously hidden in `.find_syntax_plain_text()`.
We can't use #[from] on Error::Msg(String) because String does not implement Error.
(Which it shouldn't; see e.g. https://internals.rust-lang.org/t/impl-error-for-string/8881.)
So we implement From manually for Error::Msg, since our current code was written
in that way for error-chain.
To improve startup performance, we will later load smaller `SyntaxSet`s instead
of one giant one. However, the current API assumes only one `SyntaxSet` is ever used,
and that that implicitly is the `SyntaxSet` from which returned `SyntaxReference`s
comes.
This change changes the API to reflect that `SyntaxSet` and `SyntaxReference`
are tightly coupled, and enables the use of several `SyntaxSet`.
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.
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 combines ansi-light and ansi-dark into a single theme that works
with both light and dark backgrounds. Instead of specifying white/black,
the ansi theme uses the terminal's default foreground/background color
by setting alpha=01, i.e. #00000001. This is in addition to the alpha=00
encoding where red contains an ANSI color palette number.
Now, `--theme ansi-light` and `--theme ansi-dark` will print a
deprecation notice and use ansi instead (unless the user has a custom
theme named ansi-light or ansi-dark, which would take precedence).
