## Here is an example for Ruby.

+syntax "ruby" "\.rb$" "Gemfile" "config.ru" "Rakefile" "Capfile" "Vagrantfile"

## Asciibetical list of reserved words
color statement "\b(BEGIN|END|alias|and|begin|break|case|class|def|defined\?|do|else|elsif|end|ensure|false|for|if|in|module|next|nil|not|or|redo|rescue|retry|return|self|super|then|true|undef|unless|until|when|while|yield)\b"
## Constants
color constant "(\$|@|@@)?\b[A-Z]+[0-9A-Z_a-z]*"
+color constant.number "\b[0-9]+\b"
## Ruby "symbols"
color constant (i) "([ ]|^):[0-9A-Z_]+\b"
## Some unique things we want to stand out
color constant "/([^/]|(\\/))*/[iomx]*" "%r\{([^}]|(\\}))*\}[iomx]*"
## Shell command expansion is in `backticks` or like %x{this}. These are
## "double-quotish" (to use a perlism).
-color constant "`[^`]*`" "%x\{[^}]*\}"
+color constant.string "`[^`]*`" "%x\{[^}]*\}"
## Strings, double-quoted
-color constant ""([^"]|(\\"))*"" "%[QW]?\{[^}]*\}" "%[QW]?\([^)]*\)" "%[QW]?<[^>]*>" "%[QW]?\[[^]]*\]" "%[QW]?\$[^$]*\$" "%[QW]?\^[^^]*\^" "%[QW]?![^!]*!"

## Expression substitution. These go inside double-quoted strings,
## "like #{this}".
color special "#\{[^}]*\}"
## Strings, single-quoted
-color constant "'([^']|(\\'))*'" "%[qw]\{[^}]*\}" "%[qw]\([^)]*\)" "%[qw]<[^>]*>" "%[qw]\[[^]]*\]" "%[qw]\$[^$]*\$" "%[qw]\^[^^]*\^" "%[qw]![^!]*!"
