nom - Rust parser combinator framework

  •    Rust

nom is a parser combinators library written in Rust. Its goal is to provide tools to build safe parsers without compromising the speed or memory consumption. To that end, it uses extensively Rust's strong typing and memory safety to produce fast and correct parsers, and provides macros and traits to abstract most of the error prone plumbing. If you need any help developing your parsers, please ping geal on IRC (mozilla, freenode, geeknode, oftc), go to #nom on Mozilla IRC, or on the Gitter chat room.

plotnine - A grammar of graphics for Python

  •    Python

plotnine is an implementation of a grammar of graphics in Python, it is based on ggplot2. The grammar allows users to compose plots by explicitly mapping data to the visual objects that make up the plot. Plotting with a grammar is powerful, it makes custom (and otherwise complex) plots easy to think about and then create, while the simple plots remain simple.

chevrotain - Parser Building Toolkit for JavaScript

  •    TypeScript

Chevrotain is a blazing fast and feature rich Parser Building Toolkit for JavaScript. It can be used to build parsers/compilers/interpreters for various use cases ranging from simple configuration files, to full fledged programing languages. A more in depth description of Chevrotain can be found in this great article on: Parsing in JavaScript: Tools and Libraries.




dplyr - dplyr: A grammar of data manipulation

  •    R

These all combine naturally with group_by() which allows you to perform any operation “by group”. You can learn more about them in vignette("dplyr"). As well as these single-table verbs, dplyr also provides a variety of two-table verbs, which you can learn about in vignette("two-table"). dplyr is designed to abstract over how the data is stored. That means as well as working with local data frames, you can also work with remote database tables, using exactly the same R code. Install the dbplyr package then read vignette("databases", package = "dbplyr").

vega - A visualization grammar.

  •    Javascript

Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs. With Vega you can describe data visualizations in a JSON format, and generate interactive views using either HTML5 Canvas or SVG. For documentation, tutorials, and examples, see the Vega website. For a description of changes between Vega 2 and later versions, please refer to the Vega Porting Guide.

languagetool - Style and Grammar Checker for 25+ Languages

  •    Java

LanguageTool is an Open Source proofreading software for English, French, German, Polish, Russian, and more than 20 other languages. It finds many errors that a simple spell checker cannot detect. LanguageTool is freely available under the LGPL 2.1 or later.

f2 - πŸ“±πŸ“ˆAn elegant, interactive and flexible charting library for mobile.

  •    Javascript

F2 is born for mobile, developed for developers as well as designers. It is Html5 Canvas-based, and is also compatible with Node.js, Weex and React Native. Based on the grammar of graphics, F2 provides all the chart types you'll need. Our mobile design guidelines enable better user experience in mobile visualzation projects. Special thanks to Leland Wilkinson, the author of The Grammar Of Graphics, whose book served as the foundation for F2 and G2.


g2 - G2 (The Grammar of Graphics)

  •    Javascript

G2 is a visualization grammar, a data-driven visual language with a high level of usability and scalability. It provides a set of grammars, takes users beyond a limited set of charts to an almost unlimited world of graphical forms. With G2, users can describe the visual appearance of a visualization just by one statement. Special thanks to Leland Wilkinson, the author of The Grammar Of Graphics, whose book served as the foundation for G2.

lalrpop - LR(1) parser generator for Rust

  •    Rust

Despite its name, LALRPOP in fact uses LR(1) by default (though you can opt for LALR(1)), and really I hope to eventually move to something general that can handle all CFGs (like GLL, GLR, LL(*), etc).

PEGTL - Parsing Expression Grammar Template Library

  •    C++

The Parsing Expression Grammar Template Library (PEGTL) is a zero-dependency C++ header-only parser combinator library for creating parsers according to a Parsing Expression Grammar (PEG). Grammars are written as regular C++ code, created with template programming (not template meta programming), i.e. nested template instantiations that naturally correspond to the inductive definition of PEGs (and other parser-combinator approaches).

railroad-diagrams - :steam_locomotive: A small JS+SVG library for drawing railroad syntax diagrams

  •    Python

This is a small library for generating railroad diagrams (like what JSON.org uses) using SVG, with both JS and Python ports. Railroad diagrams are a way of visually representing a grammar in a form that is more readable than using regular expressions or BNF. They can easily represent any context-free grammar, and some more powerful grammars. There are several railroad-diagram generators out there, but none of them had the visual appeal I wanted, so I wrote my own.

rust-peg - Parsing Expression Grammar (PEG) parser generator for Rust

  •    Rust

This is a simple parser generator based on Parsing Expression Grammars. Please see the release notes for updates.

lark - A modern parsing library for Python, implementing Earley & LALR(1) and an easy interface

  •    Python

Beginners: Lark is not just another parser. It can parse any grammar you throw at it, no matter how complicated or ambiguous, and do so efficiently. It also constructs a parse-tree for you, without additional code on your part. Experts: Lark lets you choose between Earley and LALR(1), to trade-off power and speed. It also contains a CYK parser and experimental features such as a contextual-lexer.

Grammar framework

  •    DotNet

The purpose of this project is doing grammatical analysis of verbal languages more complex and accuracy. The finish goal is cultural language translation from one culture to another. Project is under initial construction, targeting to globalization.

meta#

  •    CSharp

Meta# is a pattern matching library for .net, which includes a flexible grammar language, a visual studio extension and many other tools to help create custom DSLs.

PGIrony - Tookit & Examples for AST Generation with Irony

  •    

A tool-kit to ease AST generation,, and further ease grammr construction, with Irony.

A simple grammar based intellisense for Html / JavaScript

  •    Javascript

A JavaScript library to enable intellisense based on a grammar. Example: Sentence -> Greeting | Command Greeting -> "hello" Name Name -> string Command -> "execute " commandName commandName -> "test" | "build" | "verify" Then users will be guided with suggestions as they type

Line Drawing Demo

  •    WPF

This is a three-liner demo program that leverages a grammar-based approach to picture generation. It does not contain the "Line Drawing Language" itself.

vim-grammarous - A powerful grammar checker for Vim using LanguageTool.

  •    Vim

vim-grammarous is a powerful grammar checker for Vim. Simply do :GrammarousCheck to see the powerful checking. This plugin automatically downloads LanguageTool, which requires Java 8+. This plugin can use job feature on Vim 8.0.27 (or later) or Neovim. It enables asynchronous command execution so you don't need to be blocked until the check has been done on Vim8+ or Neovim.
