Asynchronous Lint Engine

Checks syntax and semantic errors in Neovim and Vim asynchronously, acting as a Vim Language Server Protocol client.

About

ALE (Asynchronous Lint Engine) provides real-time linting (syntax and semantic error checking) in Neovim and Vim, enhancing the editing experience by highlighting errors as you type. Functioning as a Language Server Protocol (LSP) client, ALE supports features like diagnostics, go-to-definition, completion, finding references, hover information, and symbol search. It also offers code fixing capabilities with command-line tools like `prettier` and `eslint`. ALE emphasizes minimal dependencies, a lightweight architecture, and near-zero configuration for better defaults.
