Notus QML: LSP para análise estática de padrões de qualidade de código QML

Abstract

Source code quality directly impacts the productivity, readability, and maintainability of software. With the growth of projects and the involvement of multiple developers, standards and best practices should be adopted to ensure readability, consistency, and ease of system maintenance. In this context, static analysis and automatic formatting tools have gained prominence, such as ESLint and Prettier. The creation of the LSP (Language Server Protocol) reinforces this trend by enabling efficient integration between editors and language servers, promoting contextual diagnostics and suggestions. However, languages such as QML (Qt Modeling Language) still lack robust and flexible solutions for code validation and standardization. Given this gap, this work aimed to develop the Notus QML Language Server Protocol, a tool focused on static analysis and standardization of QML code. The system allows the creation and execution of custom rules, validation of predefined properties, standardization of nomenclatures, automatic suggestions through snippets, and formatting of import instructions. The results obtained demonstrated that Notus QML LSP is capable of identifying inconsistencies, suggesting corrections, and assisting in code standardization, significantly contributing to the improvement of quality and productivity in the development of QML-based applications.
