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. -

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. -

Input mask for Android
User input masking library repo
Input masks restrict data input and allow you to guide users to enter correct values. Apply formatting to your text fields, see examples. Filter out nonessential symbols (e.g. extract 0123456 from +1 (999) 012-34-56) For international phone numbers. Apply number/currency formatting. Be careful when specifying the field's android:inputType. The library uses the native Editable variable received on afterTextChange event in order to replace text efficiently. Because of that, field's inputType is actually considered when the library is trying to mutate the text. For instance, having a field with android:inputType="numeric", you cannot put spaces and dashes into the mentioned Editable variable by default. Doing so will cause an out-of-range exception when the MaskedTextChangedListener will try to reposition the cursor. -

Input mask for iOS
User input masking library repo
Input masks restrict data input and allow you to guide users to enter correct values. Interface Builder struggles to support modules imported in a form of a dynamic framework. For instance, custom views annotated as IBDesignable, containing IBInspectable and IBOutlet fields aren't recognized properly from the drag'n'dropped framework. When you cut text, characters get deleted yet you won't be able to paste them somewhere as they aren't actually in your pasteboard. Shortly after new text is being pasted from the clipboard, every UITextInput receives a new value for its selectedTextRange property from the system. This new range is not consistent with the formatted text and calculated caret position most of the time, yet it's being assigned just after set caretPosition call. -

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 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. -
