SLE is defined as the application of systematic, disciplined, and measurable approaches to the development, deployment, use, and maintenance of software languages — SLEBoK (Software Language Engineering Body of Knowledge)

This is a collection of software language engineering (SLE) tools, frameworks and books.
With a focus on maintained and open-source projects.
Pull requests are very welcome!

Language Workbench

A language workbench is a software development tool designed to define, reuse and compose domain-specific languages together with their integrated development environment. Language workbenches support language-oriented programming. Language workbenches were introduced and popularized by Martin Fowler in 2005. - Wikipedia

Attribute grammar

An attribute grammar is a formal way to define attributes for the productions of a formal grammar, associating these attributes with values. The evaluation occurs in the nodes of the abstract syntax tree, when the language is processed by some parser or compiler. - Wikipedia


Broadly, any metalanguage is language or symbols used when language itself is being discussed or examined. In logic and linguistics, a metalanguage is a language used to make statements about statements in another language (the object language). Expressions in a metalanguage are often distinguished from those in an object language by the use of italics, quotation marks, or writing on a separate line. The structure of sentences and phrases in a metalanguage can be described by a metasyntax. - Wikipedia
