fmt
Formatting library as an alternative to C stdio and C++ iostreams
{fmt} is an open-source formatting library providing a fast and safe alternative to C stdio and C++ iostreams. The format API is similar in spirit to the C printf family of function but is safer, simpler and several times faster than common standard library implementations. The format string syntax is similar to the one used by str.format in Python. The library is fully type safe, automatic memory management prevents buffer overflow, errors in format strings are reported using exceptions or at compile time. The library produces compact per-call compiled code. The library is highly portable and relies only on a small set of C++11 features, like variadic templates, type traits, rvalue references, decltype, trailing return, types, deleted functions, alias templates. These are available in GCC 4.8, Clang 3.0, MSVC 19.0 (2015) and more recent compiler version. For older compilers use {fmt} version 4.x which is maintained and only requires C++98. -

dprint
Pluggable and configurable code formatting platform written in Rust
A pluggable and configurable code formatting platform written in Rust. This project is under active early development. I recommend you check its output to ensure it's doing its job correctly and only run this on code that has been checked into source control. Monorepo for dprint—a pluggable and configurable code formatting platform. The plugins property specifies which plugins to use for formatting. These may be URLs or file paths to a WebAssembly file of the plugin. By default, plugins will pull in files based on their extension. Sometimes a file may have a different extension or no extension at all, but you still want to format it with a certain plugin. The plugin "associations" config allows you to do that by associating a certain file pattern to one or multiple plugins. -

StyLua
An opinionated Lua code formatter
An opinionated code formatter for Lua 5.1, 5.2, 5.3, 5.4 and Luau, built using full-moon. StyLua is inspired by the likes of prettier, it parses your Lua codebase, and prints it back out from scratch, enforcing a consistent code style. By default, these are built with all syntax variants enabled (Lua 5.2, 5.3, 5.4 and Luau), to cover all possible codebases. If you would like to format a specific Lua version only, see installing from crates.io. You can use the stylua-action GitHub Action in your CI to install and run StyLua. This action uses the prebuilt GitHub release binaries, instead of running cargo install, for faster CI times. This command will format the foo.lua and bar.lua file, and search down the src directory to format any files within it. StyLua can also read from stdin, by using - as the file name. -

SwiftFormat
A command-line tool and Xcode Extension for formatting Swift code
SwiftFormat is a code library and command-line tool for reformatting Swift code on macOS or Linux. SwiftFormat goes above and beyond what you might expect from a code formatter. In addition to adjusting white space, it can insert or remove implicit self, remove redundant parentheses, and correct many other deviations from the standard Swift idioms. Many programmers have a preferred style for formatting their code, and others seem entirely blind to the existing formatting conventions of a project. When collaborating on a project, it can be helpful to agree on a common coding style, but enforcing that manually is tedious and error-prone, and can lead to arguments if some participants take it more seriously than others. Having a tool to automatically enforce a common style eliminates those issues, and lets you focus on the behavior of the code, not its presentation. -
17
CSharpier
CSharpier is an opinionated code formatter for c#
CSharpier is an opinionated code formatter for c#. It uses Roslyn to parse your code and re-prints it using its own rules. The printing process was ported from prettier but has evolved over time. CSharpier can also format on save in your editor or as a pre-commit hook. Then you can ensure code was formatted with a CI/CD tool. -

MegaLinter
Mega-Linter analyzes 50 languages, 22 formats, 21 tooling formats etc.
Verify your code consistency with an open-source tool. MegaLinter is an Open-Source tool for CI/CD workflows that analyzes the consistency of your code, IAC, configuration, and scripts in your repository sources, to ensure all your projects sources are clean and formatted whatever IDE/toolbox is used by their developers, powered by OX Security. Supporting 54 languages, 24 formats, 22 tooling formats and ready to use out of the box, as a GitHub action or any CI system highly configurable and free for all uses. Projects need to contain clean code, in order to avoid technical debt, which makes evolutive maintenance harder and time-consuming. By using code formatters and code linters, you ensure that your code base is easier to read and respects best practices, from the kick-off to each step of the project lifecycle. Not all developers have the good habit to use linters in their IDEs, making code reviews harder and longer to process. -

Prettier is an open source, opinionated code formatter that basically takes all the original styling of your code and enforces a consistent code style through parsing and reprinting following its own rules. It takes the maximum line length into account, wrapping code if needed. Prettier makes writing code in one consistent style automatic, painless and so much easier. No need to spend so much time, effort and mental energy discussing styles or formatting your code. Simply press save and your code is formatted. Prettier supports several languages including JavaScript, TypeScript, JSON, CSS, HTML and more. It also integrates with most editors (Atom, Visual Studio, Vim, Espresso and more). -

SQL Formatter
A whitespace formatter for different query languages
SQL Formatter is a JavaScript library for pretty-printing SQL queries. It started as a port of a PHP Library, but has since considerably diverged. It supports various SQL dialects: GCP BigQuery, IBM DB2, Apache Hive, MariaDB, MySQL, Couchbase N1QL, Oracle PL/SQL, PostgreSQL, Amazon Redshift, SingleStoreDB, Snowflake, Spark, SQL Server Transact-SQL, Trino/Presto. See language option docs for more details. The CLI tool will be installed under sql-formatter and may be invoked via npx sql-formatter. If you don't use a module bundler, clone the repository, run npm install and grab a file from /dist directory to use inside a script tag. This makes SQL Formatter available as a global variable window.sqlFormatter. -

prettierd
Prettier, as a daemon, for improved formatting speed.
Prettier, as a daemon, for improved formatting speed. Many parsers ship with prettierd, including JavaScript, TypeScript, GraphQL, CSS, HTML and YAML. Please notice that starting with version 0.12.0, prettierd now supports invoking the local version of prettier, so instead of adding new languages to prettierd, you should rely on that feature to use it locally with your custom version of prettier and enabled plugins. -
22
Prettier PHP Plugin
Prettier PHP Plugin
Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary. This plugin adds support for the PHP language to Prettier. We're considering the plugin to be stable when pure PHP files are formatted. Formatting of files that contain mixed PHP and HTML is still considered unstable. This package exposes a standalone.js that can be used alongside Prettier's own standalone.js to make the PHP plugin work in browsers without a compile step. -

Pronto
Quick automated code review of your changes
Pronto runs analysis quickly by checking only the relevant changes. Created to be used on GitHub pull requests, but also works locally and integrates with GitLab and Bitbucket. Perfect if you want to find out quickly if a branch introduces changes that conform to your style guide, are DRY, don't introduce security holes, and more. Pronto runs the checks on a diff between the current HEAD and the provided commit-ish (default is master). You can run Pronto as a step of your CI builds and get the results as comments on GitLab commits using GitlabFormatter. You can run Pronto as a step of your CI builds and get the results as comments on Bitbucket commits using BitbucketFormatter or BitbucketPullRequestFormatter. The behavior of Pronto can be controlled via the .pronto.yml configuration file. -
