Now if a cache file exists in the current directory, and the user passes
no arguments to the cache command, the cache file would be displayed.
If however the user uses cache command with arguments, the cache command
would be executed as normal regardless of whether the file cache exists
in the current directory or not.
Though now there won't be an error message displayed if the user uses the cache sub command without arguments in any directory that contains a file named cache.
- New themes in `$BAT_CONFIG_DIR/themes` are now loaded *in addition* to
the default themes (they may also override).
- The `Default.tmTheme` symlink is not necessary anymore.
This relates to #172
This changes the output color of the grid and the line numbers to use
the "gutter" foreground color defined in the Sublime `.tmTheme` files.
Sublime Text does the same.
Note: we could go one step further and also extract the "GitGutter"
colors from the themes. These could be used instead of red/green/yellow
to signify Git modifications. The problem is that they are quite a bit
harder to extract from the syntect `Theme` object.
closes#178
This commit separates the handling of syntax sets and theme sets. It
also changes the way how new syntax definitions are loaded from `bat`'s
configuration folder. New syntax definitions are now loaded *in
addition* to the ones that are stored in the `bat` binary by default.
This fixes#172
The `--theme` command line option stills takes precedence and this
change preserves how errors are handled when it's used: If a theme name
that doesn't exist is specified using the argument, this error is fatal.
However, if a theme that doesn't exist is specified using the environment
variable, the error is logged to `stderr` and the "Default" theme is
loaded as a fallback.
