注意：下面有部分代码我认为对我的问题来说已经足够了。但我也把整个脚本的zip存档放在这篇文章的末尾。
需要做什么：我需要将行" argc ; number "替换为string map [ list // $function_parameter_comment_sign ] "\" argc // number \""返回的值和行" argv ; arguments "的值{由string map [ list // $function_parameter_comment_sign ] "\" argv // arguments \""
我尝试了不同的方法：将它们包含在[]或{}中，为变量赋值并将其置于该行以及许多其他方式但未成功。我该怎么办？

假设你总是想要一个不断的替换（即，你没有在每个站点改变$function_parameter_comment_sign！）那么它并不太难。只需构建地图即可在几个阶段中应用string map。 （我不是100％确定我有你想要替换的东西，但你应该很容易从这里修复它。）
# Shared value to keep line length down
set replacer [list "//" $function_parameter_comment_sign]
# Build the map (no need to do it in one monster [list]!)
set map {}
lappend map {" argc ; number "} [string map $replacer "\" argc // number \""]
lappend map {" argv ; arguments "} [string map $replacer "\" argv // arguments \""]
# Apply the map
set theMappedText [string map $map $theInputText]
如果你想做一些事情而不是用常量替换不需要的字符串的每个实例，那么你需要使用subst就会变得更加复杂（因此你还需要额外的清理工作）步）。幸运的是，我认为你不需要那个;你的情况似乎很简单。

我不完全确定你在寻找什么，但如果我做对了，你可以尝试使用这样的东西：
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{}被用于制作列表，因此使用[list]应该会产生相同的功能，并且可以使用功能和替换功能。
