示例1: BinaryExpression
const node = path.node;
if (t.isIdentifier(node) && node.name === "n") {
node.name = "x";
}
}
});
// Examples from https://github.com/thejameskyle/babel-handbook/blob/master/translations/en/plugin-handbook.md#writing-your-first-babel-plugin
const v1: Visitor = {
BinaryExpression(path) {
if (t.isIdentifier(path.node.left)) {
// ...
}
path.replaceWith(
t.binaryExpression("**", path.node.left, t.numericLiteral(2))
);
path.parentPath.replaceWith(
t.expressionStatement(t.stringLiteral("Anyway the wind blows, doesn't really matter to me, to me."))
);
path.parentPath.remove();
},
Identifier(path) {
if (path.isReferencedIdentifier()) {
// ...
}
if (t.isQualifiedTypeIdentifier(path.node, path.parent)) {
// ...
}
},示例2: plugin
//.........這裏部分代碼省略.........
// Underscore uses them for templates though.
