eos-rc-parser

EOS Ricardian contract parser

This library strips out the {{ param }} tags and replaces it with data from the transaction itself.

Installation

npm i -S eos-rc-parser 

Usage

const parser = require('eos-rc-parser');
 
const abi = await eos.contract(contractAccountName);
const data = abi.fc.fromBuffer(action.name, action.data);
const actionAbi = abi.fc.abi.actions.find(fcAction => fcAction.name === action.name);
 

const parsedRicardianContract = parser.parse(action.name, data, actionAbi.ricardian_contract);
 
// Optional HTML formatting
const htmlOptions = {h1:'b', h2:'div class="someclass"'};
const parsedRicardianContract = parser.parse(action.name, data, ricardian, signer, true || htmlOptions);

Or constitution:

const ricardian = systemAbi.abi.ricardian_clauses[0].body;
const parsedRicardianContract = parser.constitution(ricardian, 'testaccount', {h1:'h1'});

Examples results:

No HTML formatting

parser.parse('bidname', {bid: '3 EOS', bidder: 'testaccount', newname: 'somename'}, ricardian, 'testaccount');
