External Clang Examples¶
Introduction¶
This page provides some examples of the kinds of things that people have done with Clang that might serve as useful guides (or starting points) from which to develop your own tools. They may be helpful even for something as banal (but necessary) as how to set up your build to integrate Clang.
Clang’s library-based design is deliberately aimed at facilitating use by external projects, and we are always interested in improving Clang to better serve our external users. Some typical categories of applications where Clang is used are:
- Static analysis.
- Documentation/cross-reference generation.
If you know of (or wrote!) a tool or project using Clang, please send an email to Clang’s development discussion mailing list to have it added. (or if you are already a Clang contributor, feel free to directly commit additions). Since the primary purpose of this page is to provide examples that can help developers, generally they must have code available.
List of projects and tools¶
