Fixed by implementing the proposal by sharkdp:
* Allow PAGER=bat, but ignore the setting in bat and simply default to
less. Unless of course, BAT_PAGER or --pager is used to overwrite the
value of PAGER.
* Disallow the usage of bat within BAT_PAGER and --pager.
This will fix#614 by making it clear what is wrong by showing the
following error message:
Failed to load one or more themes from
'/Users/me/.config/bat/themes' (reason: 'Invalid syntax theme
settings')
We also need to add a check if theme_dir.exists(), otherwise an absent
dir will seem like an error:
Failed to load one or more themes from
'/Users/me/.config/bat/themes' (reason: 'IO error for
operation on /Users/me/.config/bat/themes: No such file or
directory (os error 2)')
(This is the same check we already have for syntax_dir.)
To trigger/verify the changed code, run
bat --list-languages # or -L
This is the last clippy warning in the code that you get if you run
cargo clippy --all-targets --all-features -- --allow clippy::style
so by fixing it it becomes easier to spot when a new warning is
introduced (that does not belong to the clippy category clippy::style).
And by making it easy to spot new warnings, we increase chance of such
regressions not ending up in the code base.
This macro is intended to be package-internal and is not to be
considered part of the public lib API.
Use it in three places to reduce code duplication. However, main reason
for this refactoring is to allow us to fix#1063 without duplicating the
code yet another time.
The macro can also be used for the "Binary content from {} will not be
printed to the terminal" message if that message starts to use eprintln!
instead (if ever).
To trigger/verify the changed code, the following commands can be used:
cargo run -- --theme=ansi-light tests/examples/single-line.txt
cargo run -- --theme=does-not-exist tests/examples/single-line.txt
cargo run -- --style=grid,rule tests/examples/single-line.txt
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).
This fixes#1438.
Note however, that using a pager such as less will add a newline itself.
So to actually not print a newline for such files, you need to either
disable paging:
bat --style=plain --paging=never no-newline-at-end-of-file.txt
or use a "pager" that does not add a newline:
bat --style=plain --pager=cat no-newline-at-end-of-file.txt
Note that we also update syntax tests file since a bunch of them had
missing newlines on the last lines.
Since it has a functional role, we can not just replace it, we must keep
it around. This also allows us to simplify the code slightly.
We must fix this before we fix#1438 since otherwise the \n will be
missing with --style=plain, since we will stop adding it if it is
missing.
