I'm dealing with a big number of signals. I've been able to store them into a list, but since their name have brackets the signals are store in a list. Latter on, using regexp, I analyze some output produced and, if there's a match, I needed to set a flag.
In this following example I show the element added to the list and, later one, I try to check if the same element is inside of the list using lsearch
set mylist [list]
set element {aux[1]}
lappend mylist $element
puts "mylist: $mylist \nelement: $element\n\[list element\]: [list $element]"
The result of this puts is:
mylist: {aux[1]}
element: aux[1]
[list element]: {aux[1]}
Since my element is stored as {a[1]}, I've not found a way to make lsearch to return a match
set result [lsearch $mylist $element]
set result2 [lsearch $mylist [list $element]]
puts $result
puts $result2
Both results return '-1'.
I've seen solutions, but none of them using Tcl 8.4; And I need to use it due to backwards compatibility.
Use the -exact matching style. The default style is -glob, which means that the substring [1] matches a single 1.
lsearch -exact $mylist $element
# => 0
