如何在TCL中結合兩個字符串？

Question

我在TCL下面的代碼：

set string1 "do the firstthing" 
set string2 "do the secondthing" 

如何做一個組合兩個字符串在TCL "do the firstthing do the secondthing"

Answer 1

你可以使用append這樣的：

% set string1 "do the firstthing" 
% set string2 "do the secondthing" 
% append string1 " " $string2 
% puts $string1 
do the firstthing do the secondthing 

你可以把它們放在旁邊的其他...

% set string1 "do the firstthing" 
% set string2 "do the secondthing" 
% puts "$string1 $string2" 
do the firstthing do the secondthing 

或者，如果你的字符串在列表中，你可以使用join，並指定連接器...

% set listofstrings [list "do the firstthing" "do the secondthing"] 
% puts [join $listofthings " "] 
do the firstthing do the secondthing 

Answer 2

字符串連接僅僅是並列關係，

set result "$string1$string2" 
set result $string1$string 

Answer 3

使用附加命令：

set string1 "do the firstthing" 
set string2 "do the secondthing" 
append var $string1 "," $string2 
puts $var 
# Prints do the firstthing,do the secondthing
