* implemented add, mul, div, sub assign for identifiers. * Implemented struct field initialization. * Implemented imports * Implemented storage VM API (interop layer) + additional bug fixes when encountered. * Bumped version 0.12.0 * fixed double point extension on compiled output file. * Fixed bug where callExpr in returns where added to voidCall * fixed binExpr compare equal * Check the env for the gopath first * removed travis.yml * custom types + implemented general declarations. * commented out the storage test to make the build pass |

neo-go
Go Node and SDK for the NEO blockchain.
Overview
This project is currently in alpha and under active development.
Project Goals
Full port of the original C# NEO project. A complete toolkit for the NEO blockchain, including:
- Full consensus node
- Full RPC node
- RPC client
- CLI tool
- Smart contract compiler
Current State
This project is still under heavy development. Still working on internal API's and project layout. T his should not take longer than 2 weeks.
The project will exist out of the following packages:
| Package | State | Developer |
|---|---|---|
| api | started | @anthdm |
| core | started | @anthdm |
| network | started | @anthdm |
| vm | started | @anthdm |
| smartcontract | started | @revett |
| cli | started | @revett |
Getting Started
Server
Install dependencies, this requires dep:
make deps
Build the neo-go CLI:
make build
Currently, there is a minimal subset of the NEO protocol implemented. To start experimenting make sure you a have a private net running on your machine. If you dont, take a look at docker-privnet-with-gas.
Start a NEO node:
./bin/neo-go node -seed 127.0.0.1:20333
You can add multiple seeds if you want:
./bin/neo-go node -seed 127.0.0.1:20333,127.0.01:20334
By default the server will currently run on port 3000, for testing purposes. You can change that by setting the tcp flag:
./bin/neo-go node -seed 127.0.0.1:20333 -tcp 1337
RPC
If you want your node to also serve JSON-RPC, you can do that by setting the following flag:
./bin/neo-go node -rpc 4000
In this case the server will accept and respond JSON-RPC on port 4000. Keep in mind that currently there is only a small subset of the JSON-RPC implemented. Feel free to make a PR with more functionality.
VM
TODO
Smart Contracts
NOTE: At this moment there is only a small subset of the Go language implemented.
Compile a smart contract
./bin/neo-go contract compile mycontract.go
By default the filename will be the name of your .go file with the .avm extension, the file will be located in the same directory where you called the command from. If you want another location for your compiled contract:
./bin/neo-go contract compile mycontract.go --out /Users/foo/bar/contract.avm
Debugging your smart contract
You can dump the opcodes generated by the compiler with the following command:
./bin/neo-go contract opdump mycontract.go
This will result in something like this:
INDEX OPCODE DESC
0 0x52 OpPush2
1 0xc5 OpNewArray
2 0x6b OpToAltStack
3 0x 0 OpPush0
4 0x6c OpFromAltStack
5 0x76 OpDup
6 0x6b OpToAltStack
7 0x 0 OpPush0
8 0x52 OpPush2
9 0x7a OpRoll
10 0xc4 OpSetItem
