关键代码

模板配置

[config]
camealCase = true

[var]
scopeName = Test
funcName = genetate
returnType = std::string
defaultReturn = ""

[template]
${returnType} ${scopeName}::get${funcName}() const
{
auto node = getNode();
if (!node)
return ${defaultReturn};

${returnType} ${funcName} = node->${funcName}(); // 修改属性名
return ${funcName};
}

生成后

std::string Test::getGenetate() const { auto node = getNode(); if (!node) return ""; std::string genetate = node->genetate(); // 修改属性名 return genetate; }
