0.24.0 - 2020-10-20

Added

  • Add conversion methods for KeyPair and Asset
  • Stellar Protocol 14 support
    • Regenerate XDR wrappers from definitions in stellar-core 14.1.1
    • Add CAP-23 Two-Part Payments support
      • Add ClaimPredicate DSL methods which help with creation of claim predicates. 
        # use class-level helpers to create simple predicates
unconditional   = Stellar::ClaimPredicate.unconditional
before_rel_time = Stellar::ClaimPredicate.before_relative_time(1.hour)
before_abs_time = Stellar::ClaimPredicate.before_absolute_time(Date.tomorrow.beginning_of_day)

# negate predicates using `~` unary operator
~predicate # same as predicate.not

# build complex predicates using `&` and `|` infix operators
predicate & other_predicate # same as `predicate.and(other_predicate)`
predicate | other_predicate # same as `predicate.or(other_predicate)`

# quickly define complex predicates using `.compose` class method with the block
unconditional = Stellar::ClaimPredicate.compose { }
complex = Stellar::ClaimPredicate.compose do
  before_relative_time(1.week) & ~before_relative_time(10.seconds) |
end

# here's what building this predicate would look like without DSL
complex = Stellar::ClaimPredicate.new(
    Stellar::ClaimPredicateType::AND,
    Stellar::ClaimPredicate.new(
        Stellar::ClaimPredicateType::BEFORE_RELATIVE_TIME, 7 * 24 * 60 * 60
    ),
    Stellar::ClaimPredicate.new(
        Stellar::ClaimPredicateType::NOT, Stellar::ClaimPredicate.new(
            Stellar::ClaimPredicateType::BEFORE_RELATIVE_TIME, 10
        )
    )
)
      • Extend Operation with create_claimable_balance and claim_claimable_balance helpers
      • Add Claimant and ClaimPredicate DSL methods to reduce the noise. 
        include Stellar::DSL

sender = KeyPair('S....')
recipient = 'G....'

op = Operation.create_claimable_balance(
    asset: Stellar::Asset.native,
    amount: 100,
    claimants: [
      Claimant(recipient) { after(10.seconds) & before(1.week) },
      Claimant(sender), # allow unconditional claim-back
    ]
  )
])
      • Add simple predicate evaluation feature so that developers can sanity-check their predicates 
        include Stellar::DSL

predicate = ClaimPredicate { before_relative_time(1.week) & ~before_relative_time(10.seconds) }

# predicate.evaluate(balance_creation_time, claim_evaluation_time)
predicate.evaluate("2020-10-20 09:00:00", "2020-10-20 09:00:05") # => false
predicate.evaluate("2020-10-20 09:00:00", "2020-10-20 09:01:00") # => true
predicate.evaluate("2020-10-20 09:00:00", "2020-10-27 08:50:00") # => true

# you can also pass an instance of ActiveSupport::Duration as a second parameter, in this case
# it works as a relative offset from `balance_creation_time`
predicate.evaluate("2020-10-20 09:00:00", 1.week + 1.second) # => false

# it is effectively the same as
predicate.evaluate("2020-10-20 09:00:00", "2020-10-27 09:00:01") # => false
    • Add CAP-33 Sponsored Reserves support
      • Extend the operation class with helpers that allow sponsoring reserves and also revoke sponsorships.

        • Operation.end_sponsoring_future_reserves

        • Operation.revoke_sponsorship(account_id:, asset:)
        • Operation.revoke_sponsorship(account_id:, offer_id:)
        • Operation.revoke_sponsorship(account_id:, data_name:)
