Test vector

[tschudin]

returning the favor to @arj03 and providing a test vector for BIPF:

f50418666f6f8c02127fff0a800a810aff0a000a010a7f12800012007f1a0080000e002179656168061862616695014046726564686f6c6d4305413da6832fbc3f186261722868656c6c6f1862617a06

which should turn, in Python speak, into {'foo': [-129, -128, -127, -1, 0, 1, 127, 128, 32512, 32768, False, b'yeah', None], 'baf': {'Fredholm': 0.1101000100000001}, 'bar': 'hello', 'baz': None}

does this compute?

This is the memory view (key val pairs) when iterating:

@tschudin this is what I get in JS:

const bipf = require('bipf')

const tv = Buffer.from([
  0xf5, 0x04, 0x18, 0x66, 0x6f, 0x6f, 0x8c, 0x02, 0x12, 0x7f, 0xff, 0x0a, 0x80,
  0x0a, 0x81, 0x0a, 0xff, 0x0a, 0x00, 0x0a, 0x01, 0x0a, 0x7f, 0x12, 0x80, 0x00,
  0x12, 0x00, 0x7f, 0x1a, 0x00, 0x80, 0x00, 0x0e, 0x00, 0x21, 0x79, 0x65, 0x61,
  0x68, 0x06, 0x18, 0x62, 0x61, 0x66, 0x95, 0x01, 0x40, 0x46, 0x72, 0x65, 0x64,
  0x68, 0x6f, 0x6c, 0x6d, 0x43, 0x05, 0x41, 0x3d, 0xa6, 0x83, 0x2f, 0xbc, 0x3f,
  0x18, 0x62, 0x61, 0x72, 0x28, 0x68, 0x65, 0x6c, 0x6c, 0x6f, 0x18, 0x62, 0x61,
  0x7a, 0x06,
])

console.log(bipf.decode(tv))
/*

@staltz thanks for testing! Happy to see that it's quite close. Re the integer values, I guess this relates to the comment in your code: //TODO: encode in minimum bytes

[arj03]

That should probably be it @tschudin. There is a tradeoff between speed and space, but I do agree that minimal encoding of integers and doubles should be explored. More information here: https://github.com/ssbc/bipf/issues/2

I have started https://github.com/ssbc/bipf-spec that includes some fixtures.
