EOSIO C++ IntelliSense in VSCode

If you're a developer nowadays chances are high that you're using VSCode as your IDE of choice. It's my favourite IDE for web development, but I also use it for C++ EOSIO smart contract development because it's free, unlike the CLion alternative. Per default, there is no IntelliSense (code completion, jump to class definitions, etc.) for EOSIO smart contract development which is a big productivity killer. However, there's an easy way to enable it for your VSCode workspace. <ol> <li>Install and enable the <a href="https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">C/C++ IntelliSense Extension <li>Edit C++ Configuration: <code>CMD + SHIFT + P => <code>C/C++: Edit Configuration (UI) <ol> <li>In the Include paths sections add the path to your <code>eosio.cdt include directories and optionally your whole worksapce folder. ${workspaceFolder}/** /usr/local/opt/eosio.cdt/opt/eosio.cdt/include/eosiolib/core/** /usr/local/opt/eosio.cdt/opt/eosio.cdt/include/eosiolib/contracts/** <li>In the Defines section add definitions for <code>uint128_t.
