- 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.
