Moir syntax v1

Moir uses a syntax similar to Javascript's Regex with subtle differences

• Characters not in [] are treated as literals and printed as is i.e ABC => ABC
• Empty [] are treated as literals and returned as part of the generated string i.e ABC{2}[] => 'ABCC[]'
• [ABC] => A OR B OR C
• [A-Z] => Any character between A and Z
• [0-9] => Any number between 0 and 9
• Moir's cardinality operators include:

  • * (zero or more) [abc]* => '' OR 'aabbccaaaaabbbaa'

  • + (one or more) [ABC]+ => 'A' OR 'B' OR 'C' OR 'AABBABABBACC'

  • ? (zero or one) A? => '' OR 'A'

  • {N} (Exactly N) 9{3} => 999

  • {N,M} (Between N and M) @{3,4} => '@@@' OR '@@@@'

  • {N,} (At least N) u{4} => 'uuuu' OR 'uuuuuuuuuuu'

More examples

var moir = require('moir');
var random_phone = moir('+[0-9]{3}-[0-9]{4}-[0-9]{3}');
console.log(random_phone); // [phone]

var random_date = moir('19[0-9]{2}-[0-1][1-2]-[1-3][0-1]');
console.log(random_date); //1990-02-10


var random_gmail = moir('[a-z]{3}[aeiou]{1,2}[a-z]{4}_?[0-9]{0,2}@gmail.com');
console.log(random_gmail); //[e-mail]
