Glossary of terms and abbreviations used in SwiftSyntax
Abbreviations and Terms
To avoid ongoing repetition of common long terms, SwiftSyntax uses a couple of abbreviations that are common in compiler projects.
Arena See SyntaxArena
Decl Abbreviation for Declaration
Expr Abbreviation for Expression
IfConfig Abbrevation for If Configuration. Refers to #if
clauses in the source code.
Layout Node A layout node can have an arbitrary number of children and provides structure to the syntax tree. All Syntax
nodes that aren’t TokenSyntax
are layout nodes. For example a StructDeclSyntax
consists of, among others, of the struct
keyword, the name and the memberBlock
. The latter is again a layout node that contains multiple children. Layout nodes never represent any source code in the syntax tree by themselves. All source code within the syntax tree is represented by tokens.
Node A layout node or token
RawSyntax The underlying storage of syntax nodes. These are manually memory managed inside an arena. You should not need to interact with them unless contributing to swift-syntax.
Stmt Abbreviation for Statement
Token See TokenSyntax
