Ruby lsp

The Ruby LSP is an implementation of the language server protocol for Ruby, used to improve rich features in editors. It is a part of a wider goal to ruby lsp a state-of-the-art experience to Ruby developers using modern standards for cross-editor features, documentation and debugging, ruby lsp. Want to discuss Ruby developer experience?

It connects to the ruby-lsp language server gem to analyze Ruby code and enhance the user experience. Want to discuss Ruby developer experience? Consider joining the public Ruby DX Slack workspace. By default, the Ruby LSP will generate a. Additionally, it will attempt to use available version managers to select the correct Ruby version for any given project. Refer to configuration for more options. Adding method support for definition, completion, hover and workspace symbol is planned, but not yet completed.

If you haven't already done so, you'll need to first set up Ruby LSP. As of v0. There is no need to add the gem to your bundle. See the documentation for more in-depth details about the supported features. LSP tooling is typically based on static analysis, but ruby-lsp-rails actually communicates with your Rails app for some features. The addon communicates with this process over a pipe i. When extension is stopped e. Prior to v0. That approach was brittle and susceptible to the application's configuration, such as routing and middleware. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the Contributor Covenant code of conduct. The gem is available as open source under the terms of the MIT License. Skip to content.

This allows the LSP to index the correct gem versions, and to ensure formatting behavior is consistent with CI.

Features The Ruby LSP features include Semantic highlighting Symbol search and code outline RuboCop errors and warnings diagnostics Format on save with RuboCop or Syntax Tree Format on type Debugging support Running and debugging tests through VS Code's UI Go to definition for classes, modules, constants and required files Showing documentaton on hover for classes, modules and constants Completion for classes, ruby lsp, constants and require paths Fuzzy search classes, modules and constants anywhere in the project and its dependencies workspace symbol Adding method support for definition, completion, hover and workspace symbol is planned, but not yet completed.

During this time, my go-to Ruby language server has been Solargraph, which has served me well. However, the winds of curiosity recently led me to explore Ruby LSP, the newcomer in the Ruby development scene and I though to write this post to share my recent experience. Before we dive into the Solargraph vs. LSP is a standardized protocol for facilitating communication between an Integrated Development Environment IDE and a language server, enhancing the development experience. Solargraph is a veteran in the Ruby world, as it has been released in March Ruby LSP is the newcomer, it is developed by Shopify, a major player in the Ruby community and Ruby LSP aims to provide a more modern and scalable solution in the long run.

There are infinite ways in which one can configure their development environment. Not only is there a vast combination of tools that one can use such as shells, plugins, version managers, operating systems and so on , but many tools allow for customization to alter their default behaviors. Trying to account for every different setup and customization diverts efforts from improving the experience for the larger audience and increases the long term maintenance costs. Based on this, we will always: - Favor more common development setups and ways of working with Ruby - Favor defaults and conventions over customization - Aim to deliver a zero-configuration experience for common setups - Provide flexibility where possible as long as it does not compromise the default experience. Adding a more complete set of editor features or improving correctness is always desired. However, we will always prioritize the stability and the performance of Ruby LSP over adding new features. Even if a feature is useful or if a modification improves the correctness of existing functionality, if it degrades performance and negatively impacts the responsiveness of the editor it may actually result in a worse developer experience. Example : the Ruby syntax for constant references is ambiguous. Therefore, we started the semantic highlighting feature considering all constant references as namespaces, which is the token type available that more closely represents the three possibilities. To improve highlighting correctness, the Ruby LSP must resolve the references to figure out to which declaration they point to, so that we can assign the correct token type class, namespace or constant.
