Tcl。如何用字符串映射返回的值替换代码行？

字符串映射[list//$function\u parameter\u comment\u sign]“argc//number\”“argc；number”字符串映射返回的值替换行“argv；arguments”

unittest.tclutest_-utils.tclgen_-test.tcl下载整个代码的代码链接：假设您总是希望不断地进行替换（即，您不会在每个站点上改变
$function\u parameter\u comment\u sign字符串映射即可。（我不能100%确定我有你想要替换的东西，但从这里开始修复应该很容易。）
如果您不想用常量替换不需要的字符串的每个实例，那么事情将变得更加复杂，因为您需要使用subst
（因此还需要额外的清理步骤）.幸运的是，我认为您不需要这样做；您的案例似乎很简单。我不完全确定您在寻找什么，但如果我做对了，您可以尝试使用以下方法：
good_signature_tcl [list "" \
"" \
[string map [list // $function_parameter_comment_sign] " argc // number "] \
[string map [list // $function_parameter_comment_sign] " argv // arguments "] \
" " \
] procedure public { "argc" "argv" } ""
由于您的{}
正被用于创建列表，因此使用[list]
应该会产生同样的结果，因为函数和替换可以工作。对不起，我没有正确解释我的问题。这是上面代码的过程调用。我需要传递过程，而不是“argc；number”
表示“argc$var1号”
并代替“argv；参数”
表示“argv$var2参数”
。我该怎么做？$var1
和$var2
是保存字符串映射
操作结果的变量，这是我的问题。非常感谢！这正是我想要的。
