TON FunC Contest #1 - solutions and tests

These are my solutions and tests for the TON Foundations's 1st smart contract developement contest for TON blockchain:

https://github.com/ton-blockchain/func-contest1

Project structure

/func - my contest solutions (all tasks)
/tests - toncli tests (tasks 1, 2, 3)
/js - TypeScript tests (tasks 1, 4, 5)

toncli tests

Install toncli and TON binaries, then run toncli tests with:

toncli run_tests -c task2

Initial project structure and toncli tests are based on: https://github.com/disintar/task-1-playground

TypeScript tests

Install TypeScript and project dependencies (once, in the root folder):

npm install -g typescript
npm install -g ts-node
npm install

To lanuch tests, run (from the root folder):

ts-node-esm ./js/tests_N.ts

Make sure this line in the tests_N.ts file:

let contract = await contractLoader('./../func/4.fc')(initialData);

points at the correct contract location

Errors

No exported member 'ExecutionResult'

If you get:

TSError: ⨯ Unable to compile TypeScript:
js/shared.ts:151:52 - error TS2694: Namespace '"/root/TON-FunC-contest-1/node_modules/ton-contract-executor/dist/index"' has no exported member 'ExecutionResult'.

then in the file: /node_modules/ton-contract-executor/dist/executor/SmartContract.d.ts change line 24 to:

export declare type ExecutionResult = FailedExecutionResult | SuccessfulExecutionResult;

(add "export" at the beginning)

Windows, Linux

If you are not on Mac, you'll get something like:

/bin/sh: 1: /root/TON-FunC-contest-1/node_modules/ton-compiler/bin/macos/func: Exec format error
/root/TON-FunC-contest-1/node_modules/ton-contract-executor/dist/vm-exec/vm-exec.js:147
      throw ex;

that's because ton-compiler package only officially works on MacOS. I found a way to fix it on Windows: install toncli and then replace the macos folder from above with the TON binaries folder (the one containing func.exe, fift.exe and where you placed libcrypto-1_1-x64.dll). It should work after this. Something similar will probably work on Linux.

Installing toncli is likely not necessary, you may try the fix above with just TON binaries. It's also probably not necessary to copy the entire TON binaries folder. Maybe copying just func.exe and fift.exe is going to be enough. But I tried neither of this. Storage is cheap.
