Welcome to Extra Clang Tools

We start by creating a new clang-tidy check. We then examine the Abstract Syntax Tree to determine how it relates to the source code, prototype a Matcher to process the AST and use the Clang FixItsystem to replace patterns in the source code. This process is iterated until all relevant patterns are ported by the … See more Let’s start with intent and motivation to get everyone on the same page.
