abieos

Binary <> JSON conversion using ABIs. Compatible with languages which can interface to C; see src/abieos.h.

Alpha release. Feedback requested.

Packing transactions

1. Create a context: abieos_create
2. Use abieos_set_abi to load eosjs2/src/transaction.abi into contract 0.
3. Use abieos_set_abi to load the contract's ABI.
4. Use abieos_json_to_bin and abieos_get_bin_hex to convert action data to hex. Use abieos_get_type_for_action to get the action's type.
5. Use abieos_json_to_bin and abieos_get_bin_hex to convert transaction to hex. Use contract = 0 and type = abieos_string_to_name(context, "transaction").
6. Destroy the context: abieos_destroy

Usage note

abieos expects object attributes to be in order. It will complain about missing attributes if they are out of order.
