There are three types of logical operators in Rell: AND, OR System library This section covers Rell's system libraries, including immutable entities, namespaces for blockchain access, built-in functions, the require function for validation, partial Simple types In Rell, there are several simple data types to represent different kinds of data. Here's an overview of the fundamental types you'll use. Define the Book entity In Rell, entities are similar In Rell, the fundamental building blocks of programming are encapsulated within basic statements. Chromia provides a postchain-client that allows you to link your dapp's frontend to the decentralized backend running on Chromia's blockchain network. Complex data types in the Rell programming language provide advanced features and capabilities beyond basic types like integers and strings. You can use the repl command (chr repl) to run specific Rell methods in the shell, which can be suitable for Install VS Code plugin This topic contains instructions to install the Rell plugin for Visual Studio Code. rell file or a directory Expressions in Rell are used to perform operations and control program flow, combining data, variables, and operators. These operations are automatically executed at specific points in the blockchain lifecycle Iterable values introduce a unified concept for processing sequences in various data structures. Function In Rell, functions streamline repetitive tasks by encapsulating reusable logic, such as validation or data retrieval. These statements enable you to perform a wide range of operations, from Rell's approach to defining operations allows for straightforward and efficient manipulation of the state without the complexities of managing gas fees, as Chromia does not have gas fees. Module definitions Module definitions in Rell create reusable code components, including entities, objects, structs, enums, queries, operations, and functions. This example demonstrates building a simple English Auction in both Solidity and Rell, Chromia's language. Virtual types use Merkle trees to efficiently verify data integrity and selectively retrieve specific elements. The postchain-client When statement In Rell, when statement is similar to switch in C++ or Java, but uses the syntax of when in Kotlin. It offers developers a powerful environment for building Rell is a programming language specifically designed for dapp development on the Chromia blockchain. Unlike traditional platforms that rely on virtual machines, Rell takes a language Rell is a language for relational blockchain programming. Chromia dapp overview Before we start with code examples, let's take a quick look at the architecture of Chromia and talk a bit about the programming language Rell.
