Detailed Description

Simplified description of a clang AST node.

This is clangd's internal representation of C++ code.

Member Data Documentation

arcana

std::string clang::clangd::ASTNode::arcana

A one-line dump of detailed information about the node.

This includes role/kind/description information, but is rather cryptic. It is similar to the output from clang -Xclang -ast-dump. May be empty for certain types of nodes.

children

std::vector<ASTNode> clang::clangd::ASTNode::children

Nodes nested within this one, such as the operands of a BinaryOperator.

Definition at line 2029 of file Protocol.h.

Referenced by clang::clangd::operator<<(), and clang::clangd::toJSON().

detail

std::string clang::clangd::ASTNode::detail

Brief additional information, such as "||" for the particular operator.

The information included depends on the node kind, and may be empty.

kind

std::string clang::clangd::ASTNode::kind

The specific kind of node this is, such as "BinaryOperator".

This is usually a concrete node class (with Expr etc suffix dropped). When there's no hierarchy (e.g. TemplateName), the variant (NameKind).

range

std::optional<Range> clang::clangd::ASTNode::range

The range of the original source file covered by this node.

May be missing for implicit nodes, or those created by macro expansion.

role

std::string clang::clangd::ASTNode::role

The general kind of node, such as "expression" Corresponds to the base AST node type such as Expr.
