// In Solidity, a mapping is like a hashmap and works with `string` like this: | |
// mapping (string => uint) a; | |
// | |
// However it doesn't support accessors where string is a key: | |
// mapping (string => uint) public a; | |
// | |
// "Internal compiler error: Accessors for mapping with dynamically-sized keys not yet implemented." | |
// | |
// An accessor returns uint when called as `a(string)`. |

This document will walk you through how to deploy your first module to Testnet using the Command Line. To achieve this, we will use the pact
command line tool's API Request formatter (pact -a
) and the curl
command line tool.
We will be deploying the following pact module. For simplicity's sake, this walkthrough expects that the pact code we are deploying is not using a transaction's data
field (read-keyset
is one such pact function that makes use of this field). Otherwise, the accompanying YAML file will have to change. We also assume that this pact code is saved as test.pact
.
