// Exposing clang's AST can give insight into the precise meaning of code.
|
|
// (C++ is a complicated language, and very few people know all its rules).
|
|
// Despite the name, clang's AST describes *semantics* and so includes nodes
|
|
// for implicit behavior like conversions.
|
|
//
|
|
// It's also useful to developers who work with the clang AST specifically,
|
|
// and want to know how certain constructs are represented.
|
|
//
|
|
// The main representation is not based on the familiar -ast-dump output,
|
|
// which is heavy on internal details.
|
|
// It also does not use the -ast-dump=json output, which captures the same
|
|
// detail in a machine-friendly way, but requires client-side logic to present.
|
|
// Instead, the key information is bundled into a few fields (role/kind/detail)
|
|
// with weakly-defined semantics, optimized for easy presentation.
|
|
// The -ast-dump output is preserved in the 'arcana' field, and may be shown
|
|
// e.g. as a tooltip.
|
|
//
|
|
// The textDocument/ast method implemented here is a clangd extension.
