urbit-ob, but in Dart #
This is urbit-ob but in dart, and only implementing the functions I care about:
- works in VM & JS runtimes
- test suite that matches urbit-ob
import 'package:urbit_ob/urbit_ob.dart' as ob; final point = BigInt.from(19268096); final data = BigInt.from(2884880786); final name = "~bosnyt-raddux"; // patp assert(ob.patp(point) == name); assert(ob.patp2dec(name) == point); // patq assert(ob.patq(encodeBigInt(data)) == name); assert(ob.patq2buf(name) == encodeBigInt(data));
idk how to encode strings that match BN.js's encoding, so string patqs won't be compatible between dart and js until that works
for example, if you encode 'hello world' as a utf8 byte list in dart, you'll get
utf8.encode('hello world'); // -> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]
but when you encode a string as a byte array using BN.js you get
new BN('hello world').toArray() // -> [ 4, 86, 168, 105, 235 ]
look they work in the vm!
pub run test
whoa, they work in chrome!
puh run test -p chrome
