~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This provides SassC_ compliant CLI executable named :program:`pysassc`:
.. sourcecode:: console
$ pysassc
Usage: pysassc [options] SCSS_FILE [CSS_FILE]
There are options as well:
.. option:: -t <style>, --style <style>
Coding style of the compiled result. The same as :func:`sass.compile()`
function's ``output_style`` keyword argument. Default is ``nested``.
.. option:: -s <style>, --output-style <style>
Alias for -t / --style.
.. deprecated:: 0.11.0
.. option:: -I <dir>, --include-path <dir>
Optional directory path to find ``@import``\ ed (S)CSS files.
Can be multiply used.
.. option:: -m, -g, --sourcemap
Emit source map. Requires the second argument (output CSS filename).
The filename of source map will be the output CSS filename followed by
:file:`.map`.
.. versionadded:: 0.4.0
.. option:: -p, --precision
Set the precision for numbers. Default is 5.
.. versionadded:: 0.7.0
.. option:: --source-comments
Include debug info in output.
.. versionadded:: 0.11.0
.. option:: --sourcemap-file
Output file for source map
.. versionadded:: 0.17.0
.. option:: --sourcemap-contents
Embed sourcesContent in source map.
.. versionadded:: 0.17.0
.. option:: --sourcemap-embed
Embed sourceMappingUrl as data URI
.. versionadded:: 0.17.0
.. option:: --omit-sourcemap-url
Omit source map URL comment from output
.. versionadded:: 0.17.0
.. option:: --sourcemap-root
Base path, will be emitted to sourceRoot in source-map as is
.. versionadded:: 0.17.0
.. option:: -v, --version
