fixabi

Adds secondary indexes to ABI files

To-do

• Check if this is correct: currently, checksum256 C++ type is mapping to sha256 ABI type and the i256 ABI type is not generated.

Requirements

• perl
• jq (not mandatory; for indented output only)

Usage

fixabi.pl processes only one input C++ file at a time. If the source for the ABI is spread across multiple files, you have to call fixabi.pl for each one, and pass the output file as the input file of the next call.

$ chmod +x fixabi.pl
$ ./fixabi.pl
Usage: ./fixabi.pl <input ABI file> <input C++ file> [output ABI file]

Example (if you put it in a directory in your PATH):

~/doh/doh-hegemon-contract$ fixabi.pl build/hegemon/hegemon.abi include/hegemon.hpp fixed.json
~/doh/doh-hegemon-contract$ diff fixed.json build/hegemon/hegemon.abi
  (...)
~/doh/doh-hegemon-contract$ cp fixed.json build/hegemon/hegemon.abi

Spec

Example entry for a table before post processing :

        {
            "name": "players",
            "type": "player",
            "index_type": "i64",
            "key_names": [],
            "key_types": []
        }

This is the table index definition.

      typedef eosio::multi_index< "players"_n, player,
           indexed_by<"unique"_n, const_mem_fun<player, uint64_t, &player::by_unique>>,
           indexed_by<"faction"_n, const_mem_fun<player, uint64_t, &player::by_faction>>,
           indexed_by<"location"_n, const_mem_fun<player, uint64_t, &player::by_location>>,
           indexed_by<"locafaction"_n, const_mem_fun<player, uint128_t, &player::by_location_faction>>> players_table;

When post-processing is complete, the resulting table entry in the ABI should be this:

        {
            "name": "players",
            "type": "player",
            "index_type": "i64",
            "key_names": ["unique", "faction", "location", "locafaction"],
            "key_types": [i64, i64, i64, i128]
        }

Supported key_types are : i64, i128, i256, float64, float128, ripemd160, sha256
