gemでsassをインストールしてコンパイルしてみるメモ

メモです。

# sassのインストール(compassでまとめてインストールしてみます)
$ gem install compass

# test.scssの作成
$ mkdir scss
$ cd scss
$ vim test.scss

# test.scssに以下を記述
#main{
 h1{ margin-bottom: 20px }
 p{ font-size:90% }
}

# コンパイルと内容の確認
$ scss test.scss test.css
$ more test.css 
#main h1 {
  margin-bottom: 20px; }
#main p {
  font-size: 90%; }

# ヘルプコマンドを実行
$ scss -h
Usage: scss [options] [INPUT] [OUTPUT]

Description:
  Converts SCSS or Sass files to CSS.

Options:
    -s, --stdin                      Read input from standard input instead of an input file
        --trace                      Show a full traceback on error
        --unix-newlines              Use Unix-style newlines in written files.
        --sass                       Use the Indented syntax.
        --watch                      Watch files or directories for changes.
                                     The location of the generated CSS can be set using a colon:
                                       scss --watch input.scss:output.css
                                       scss --watch input-dir:output-dir
        --update                     Compile files or directories to CSS.
                                     Locations are set like --watch.
        --stop-on-error              If a file fails to compile, exit immediately.
                                     Only meaningful for --watch and --update.
        --poll                       Check for file changes manually, rather than relying on the OS.
                                     Only meaningful for --watch.
    -f, --force                      Recompile all Sass files, even if the CSS file is newer.
                                     Only meaningful for --update.
    -c, --check                      Just check syntax, don't evaluate.
    -t, --style NAME                 Output style. Can be nested (default), compact, compressed, or expanded.
        --precision NUMBER_OF_DIGITS How many digits of precision to use when outputting decimal numbers. Defaults to 3.
    -q, --quiet                      Silence warnings and status messages during compilation.
        --compass                    Make Compass imports available and load project configuration.
    -g, --debug-info                 Emit extra information in the generated CSS that can be used by the FireSass Firebug plugin.
    -l, --line-numbers               Emit comments in the generated CSS indicating the corresponding source line.
        --line-comments
    -i, --interactive                Run an interactive SassScript shell.

    -r, --require LIB                Require a Ruby library before running Sass.
        --cache-location PATH        The path to put cached Sass files. Defaults to .sass-cache.
    -C, --no-cache                   Don't cache to sassc files.
    -E encoding                      Specify the default encoding for Sass files.
