Example 3 with DefineExpressionCode

use of jetbrick.template.parser.code.DefineExpressionCode in project jetbrick-template-1x by subchen.

the class JetTemplateCodeVisitor method visitMacro_directive.

@Override

            scopeCode.define(c.getName(), c.getTypedKlass());
        }
    }
    // 需要先定义 macro，这样可以支持 macro 的递归调用 (issue 102)
    if (macroMap == null) {
        macroMap = new HashMap<String, MacroCode>(8);
    }
    MacroCode old = macroMap.put(name, macroCode);
    if (old != null) {
        throw reportError("Duplicated macro defination " + name, ctx);
    }

    // 访问 macro body
    // add body content
    scopeCode.setBodyCode(ctx.block().accept(this));
