TCL的搜索行为

Question

lsearch的奇怪问题没有表现.我可能做了一些愚蠢的事.任何想法/帮助将非常感谢!

set mylist {}

lappend mylist a
lappend mylist b
lappend mylist c

set test [lsearch -exact mylist b]
puts "This doesn't work, result should be 1 = $test"

set test2 [lsearch {a b c d e} c]
puts "This works, result should be 2 = $test2"

Answer 1

您正在搜索包含单个元素的列表:

{mylist}

您需要传递变量mylist:

lsearch -exact $mylist b
