    google-java-format

    google-java-format

    Reformats Java source code to comply with Google Java Style

    google-java-format is a program that reformats Java source code to comply with Google Java Style. The formatter can act on whole files, on limited lines, on specific offsets, passing through to standard-out (default) or altered in-place. There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format. The formatter can be used in software that generates java to output more legible java code. Just include the library in your maven/gradle/etc. configuration. A google-java-format IntelliJ plugin is available from the plugin repository. To install it, go to your IDE's settings and select the Plugins category. Click the Marketplace tab, search for the google-java-format plugin, and click the Install button.

    LuaFormatter

    LuaFormatter

    Code formatter for Lua

    Reformats your Lua source code. The program will attempt to automatically use the current directory's .lua-format file if no config file is passed in the command line. If none is found, it will try to locate a .lua-format file in a parent directory recursively. On Linux, it will use $XDG_CONFIG_HOME/luaformatter/config.yaml if .lua-format does not exist. In case there's no file, it will fall back to the default configuration. The program will give the top priority to the configuration values given in the command line, then to the configuration files, and finally to the hard-coded default values.

    SwiftFormat

    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.

    dprint

    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.

    Buildtools for bazel

    A bazel BUILD file formatter and editor

    This repository contains developer tools for working with Google's bazel buildtool. buildifier For formatting BUILD, BUILD.bazel and BUCK files in a standard way. buildozer For doing command-line operations on these files. unused_deps For finding unneeded dependencies in java_library rules. See instructions in each tool's directory. Buildifier supports the following file types: BUILD, WORKSPACE, .bzl, and default, the latter is reserved for Starlark files buildifier doesn't know about (e.g. configuration files for third-party projects that use Starlark). The formatting rules for WORKSPACE files are the same as for BUILD files (both are declarative and have stricter formatting rules), and default files are formatted similarly to .bzl files, allowing more flexibility. Different linter warnings may be limited to any subset of these file types.
