$ npm install --save siscom

example

var
siscom = require('siscom'),
P = siscom.Parsers,
C = siscom.Combinators;

var
x = C.some(P.string('x')),
y = P.string('y'),
z = C.some(P.string('z'));

var
parser = C.times(2, C.sequence(C.choice(x, z), y));

console.log(siscom.parseString(parser, "xxyzzy"));
// => [[['x', 'x'], 'y'], [['z', 'z'], 'y']]

feature

  • A parser object is usual JavaScript function.

  • A parsing error is usual JavaScript error, and it is very useful, for it has many informations for debugging.
    for example:

    <string>:1: expected "y"
xxyzz
     ^

  • API looks like parsers library of Haskell.
