Create Your Contract

Official Docs

https://docs.inery.io/docs/category/tutorials/

• Download Tools

git clone https://github.com/inery-blockchain/inery.cdt

• Export inery.cdt

nano ~/.bashrc

Lalu paste ini kedalam file .bashrc taruh saja paling bawah

export PATH="$PATH:/root/inery.cdt/bin"

Dan simpan CTRL+X Y Enter

• Buat directory inrcrud

mkdir inrcrud

• Pindah directory

cd inrcrud cd; source .bashrc; cd -

• Buat file baru inrcrud.cpp

nano inrcrud.cpp

• Copy semua code ini, dan paste kedalam file inrcrud.cpp

#include <inery/inery.hpp> #include <inery/print.hpp> #include <string> using namespace inery; using std::string; class [[inery::contract]] inrcrud : public inery::contract { public: using inery::contract::contract; [[inery::action]] void create( uint64_t id, name user, string data ) { records recordstable( _self, id ); auto existing = recordstable.find( id ); check( existing == recordstable.end(), "record with that ID already exists" ); check( data.size() <= 256, "data has more than 256 bytes" ); recordstable.emplace( _self, [&]( auto& s ) { s.id = id; s.owner = user; s.data = data; }); print( "Hello, ", name{user} ); print( "Created with data: ", data ); } [[inery::action]] void read( uint64_t id ) { records recordstable( _self, id ); auto existing = recordstable.find( id ); check( existing != recordstable.end(), "record with that ID does not exist" ); const auto& st = *existing; print("Data: ", st.data); } [[inery::action]] void update( uint64_t id, string data ) { records recordstable( _self, id ); auto st = recordstable.find( id ); check( st != recordstable.end(), "record with that ID does not exist" ); recordstable.modify( st, get_self(), [&]( auto& s ) { s.data = data; }); print("Data: ", data); } [[inery::action]] void destroy( uint64_t id ) { records recordstable( _self, id ); auto existing = recordstable.find( id ); check( existing != recordstable.end(), "record with that ID does not exist" ); const auto& st = *existing; recordstable.erase( st ); print("Record Destroyed: ", id); } private: struct [[inery::table]] record { uint64_t id; name owner; string data; uint64_t primary_key()const { return id; } }; typedef inery::multi_index<"records"_n, record> records; };

Lalu simpan

• Setelah itu, Compile

inery-cpp inrcrud.cpp -o inrcrud.wasm

Cek menggunakan command ls apakah sudah generate file inrcrud.abi inrcrud.wasm atau belum

• Unlock wallet

cline wallet unlock -n NamaWallet

• Lalu hubungkan akun mu Crud Contract

cline set contract NamaAkun ./ --json

Simpan semua “block_num” dari transaksi mu, untuk mengecek di explorer nantinya

• Selanjutnya create contract

cline push action NamaAkun create '[1, "NamaAkun", "The First Contract by me"]' -p NamaAkun --json

• Coba untuk read contract

cline push action NamaAkun read [1] -p NamaAkun --json

• Ubah data contract

cline push action NamaAkun update '[ 1, "First Modify to my Contract"]' -p NamaAkun --json

• Lakukan update data beberapa kali

cline push action NamaAkun update '[ 1, "Bebas Isi Apapun Disini"]' -p NamaAkun --json

Karena task nya disuruh push some transaction, jadi jangan cuma update sekali

• Create Token menggunakan ID yang berbeda

cline push action NamaAkun create '["2", "NamaAkun", "1000000.0000 YUHUU"]' -p NamaAkun --json

• Cobalah untuk mencetak beberapa token sepeti task 2

cline push action NamaAkun issue '["2", "NamaAkun", "1000000.0000 YUHUU", "YO!"]' -p NamaAkun --json

Akan muncul error karena tidak ada fungsi issue didalam contract dan juga tidak dapat di transfer

• Langkah terakhir, cobalah untuk menghapus token di ID 2. Ini bisa dihapus karena ada fungsi destoy didalam contract

cline push action NamaAkun destroy [2] -p NamaAkun --json

Kalo ngga di approve ku update lagi kapan-kapan💜
