header "^#!.*/(env +)?crystal( |$)"
## Asciibetical list of reserved words
color statement "\b(BEGIN|END|abstract|alias|and|begin|break|case|class|def|defined\?|do|else|elsif|end|ensure|enum|false|for|fun|if|in|include|lib|loop|macro|module|next|nil|not|of|or|pointerof|private|protected|raise|redo|require|rescue|retry|return|self|sizeof|spawn|struct|super|then|true|type|undef|union|uninitialized|unless|until|when|while|yield)\b"
## Constants
color constant "(\$|@|@@)?\b[A-Z]+[0-9A-Z_a-z]*"
color constant.number "\b[0-9]+\b"
## Crystal "symbols"
color constant (i) "([ ]|^):[0-9A-Z_]+\b"
## Some unique things we want to stand out

## Regular expressions

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