What is a CLANG file? A CLANG file is a plain text file that defines a custom programming language's functions, constructors, and other code. Developers use CLANG files to describe custom languages they've created, so others can understand and code in those languages.

More Information Many programmers create custom programming languages, in hopes of improving on existing languages. These custom languages are often variants of existing languages, which borrow concepts from other languages or include slight tweaks to an existing language's functions. One way developers describe their custom languages to others is by creating a CLANG file. The CLANG file lists the functions, constructors, and other code the developer's language uses. It may also include comments explaining the developer's language and additional example code.
