Cadence Standard Library Wishlist Grant #179

Open j1010001 opened 1 year ago

j1010001 commented 1 year ago

Overview

This grant proposes tasks related to the Cadence Standard Library, which extend its functionality and are ordered in increasing difficulty / effort.

Problem

The Standard Library of Cadence is currently relatively small and only offers essential features. However, it is still missing some essential and useful functionality. This has led to the community creating smart contracts that provide some of the missing functionality.

Providing such functionality as directly in Cadence as built-ins has several advantages over implementing them in smart contracts:

This grant is structured specifically to enable and encourage new Flow contributors to progressively demonstrate their skills and abilities by working through a diverse range of problems with an increasing level of challenge. Each task has a discrete grant award for completion, providing that all technical standards and quality expectations have been met. Issue-specific expectations are defined within issue descriptions, however, the general expectation for all items will be:

Solution

Please see each respective issue for a detailed description, requirements and acceptance criteria.

Requirements

The community developer selected for this grant must submit each fix PR individually in the prescribed order below. This is to ensure work quality as the challenge increases and that contributions meet engineering and quality expectations for Flow. Through this process we can guide and support you and enable you to demonstrate a broader range of problem solving skills. Contributors who consistently meet the expected engineering quality expectations through the course of this grant will be invited to take on larger, more challenging, and rewarding grants for Flow.

About Me

I'm a Software Engineer with ~5 years of technical experience. My primary skills include C++, C, Rust & TypeScript. Recently picked up Go & Scala. I have the past experience of implementing an interpreter for a DSL.

I am a new but an active contributor to Cadence and have contributed to a few standard library related issues. Working on this grant would help solidify my understanding of Cadence & the Flow blockchain.

I have also made some contributions to the interpreter for the smart contract language of the Ergo blockchain.
