구문

function renameVarrefsInFunc(
  f: FuncDecl,
  rename: (name: string) => string | undefined,
): FuncDecl

매개변수

f FuncDecl: The function whose body is rewritten.
rename (name: string) => string | undefined: Maps a current variable name to its new name, or returns undefined to keep the current name.

반환값

FuncDecl

A copy of f with the renamed body, or f itself when no reference was renamed.

설명

Every variable reference (an expression with op: 'varref') is passed to rename by name. When rename returns a string, the reference is re-pointed at that name; when it returns undefined, the reference is kept as is. Unchanged references keep their original objects, and f itself is returned when no name changed (see rewriteExprsInFunc).

예제

// Point reads of the `u` uniform block at `u_split`.
const g = renameVarrefsInFunc(f, (name) =>
  name === 'u' ? 'u_split' : undefined,
)
