Rainbow

Raku source code lexer

Synopsis

use Rainbow;

my %mapping =
    TEXT     => '#ffffff',
    KEYWORD  => "#e04c86",
    OPERATOR => "#e04c86",
    TYPE     => "#00ffff",
    ROUTINE  => "#978deb",
    STRING   => "#68f3ca",
    # ...
;

my $code = 'my $greet = "hello"; say "Oh $greet there!";';

my @tokens = Rainbow::tokenize($code);

my @fragments = @tokens.map: -> $t {
    my $color = %mapping{$t.type.key} // %mapping<TEXT>;
    say "$color: {$t.text}";
}

Description

This module can turn a piece of Raku code into a list of tokens. Assign each token a color and you have made yourself a Raku syntax highlighter.

See lib/Rainbow/Token.rakumod for the complete list of tokens.
