X, or Masala eXtensions

This is some useful snippets condensed in an easy api

X.take

X.take() is a simplified Genlex where you define tokens, and tehey have by default classic separators ()

const c = C.char('x')
const p =X.take(['<', c.rep(), ">"]).map(t=> t.join(''));

const val = p.val("<xx x >");
expect(val).toBe('<xxx>')

Separators are by default

separator = C.charIn(' \r\n\f\t').drop();

but can be changed

const c = C.char('x')
const p =X.take(['<', c.rep(), ">"], C.char('-') ).map(t=> t.join(''));

const val = p.val("<-x---x-x->");
expect(val).toBe('<xxx>')

It's also possible to combine multiple take, like it's done in the Json parser

return take([attribute, take([COMMA.drop(), attribute]).optrep()])

X.tryAll

It combines multiple

F.try(x).or(F.try(y)).or(F.try(z))

into

X.tryAll([x, y, z])

X.json

It's a reusable json parser (WIP)
