sass-convert の使い方

sass-convert –help で使い方を確認します。

$ sass-convert --help
Usage: sass-convert [options] [INPUT] [OUTPUT]
 
Description:
  Converts between CSS, indented syntax, and SCSS files. For example,
  this can convert from the indented syntax to SCSS, or from CSS to
  SCSS (adding appropriate nesting).
 
Common Options:
    -F, --from FORMAT                The format to convert from. Can be css, scss, sass.
                                     By default, this is inferred from the input filename.
                                     If there is none, defaults to css.
    -T, --to FORMAT                  The format to convert to. Can be scss or sass.
                                     By default, this is inferred from the output filename.
                                     If there is none, defaults to sass.
    -i, --in-place                   Convert a file to its own syntax.
                                     This can be used to update some deprecated syntax.
    -R, --recursive                  Convert all the files in a directory. Requires --from and --to.
    -?, -h, --help                   Show this help message.
    -v, --version                    Print the Sass version.
 
Style:
        --dasherize                  Convert underscores to dashes.
        --indent NUM                 How many spaces to use for each level of indentation. Defaults to 2.
                                     "t" means use hard tabs.
        --old                        Output the old-style ":prop val" property syntax.
                                     Only meaningful when generating Sass.
 
Input and Output:
    -s, --stdin                      Read input from standard input instead of an input file.
                                     This is the default if no input file is specified. Requires --from.
    -E, --default-encoding ENCODING  Specify the default encoding for input files.
        --unix-newlines              Use Unix-style newlines in written files.
                                     Always true on Unix.
