    Laravel Pint is an opinionated PHP code-style fixer for minimalists. Pint is built on top of PHP-CS-Fixer and makes it simple to ensure that your code style stays clean and consistent.

    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.

    fmt

    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.

    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.

    Buildtools for bazel

    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.
