Open Source Julia Code Formatters

Width-sensitive formatter for Julia code. Inspired by gofmt, refmt, black, and prettier. Built with CSTParser. Sane defaults out of the box with options to customize. Supports YAS, Blue and SciML style guides. JuliaFormatter.toml configuration file to store options. JuliaFormatter exports format, format_file, format_text, and format_md. format_md has the same API as format_text but differ in that format_md expects the text content to be a Markdown document. See format_text docstring for formatting options at the text level and format_file docstring for formatting options at the file level. JuliaFormatter should work on any valid Julia and Markdown files. If JuliaFormatter cannot parse the code for any reason, it will throw an error pointing to the line that could not be parsed. If running format on multiple files, you may want to set verbose = true to print information about which file is being formatted.

vim-codefmt is a syntax-aware code formatting plugin for Vim that provides a unified interface to many best-in-class formatters across languages. It exposes simple commands to format either a selected range or an entire buffer, and integrates cleanly into everyday editing workflows. The plugin ships with a registry of built-in formatters and a pluggable architecture, allowing other plugins to register additional formatters without friction. Configuration is handled through maktaba and Glaive flags, so you can choose per-filetype tools, pass custom options, or point to specific formatter executables. Autoformat can be enabled via standard Vim autocommands, making it easy to format on filetype or on write while still allowing opt-out on a per-buffer basis. With broad language coverage—from C, C++, Java, Python, and Go to Kotlin, Rust, Swift, Bazel, Markdown, and more—vim-codefmt helps teams maintain consistent style across heterogeneous codebases.
