 Posted: Mon Sep 28, 2009 12:28 pm Post subject: Arrays with strings? |
 |
|
Hey guys,
I was wondering if there is any kind of arrays where you can use strings. In a normal array, syntax is something like:
| Code: |
array set <arrayname> {
Type Value
}
|
e.g.
| Code: |
array set blah {
prizes 19
victories 44
lostgames 6
}
|
What if I wanted to use strings instead of numbers in the array values?
e.g.
| Code: |
array set messages {
#channel 1 "I'm trying to make strings working on arrays"
#channel2 "This is the message that will be shown on channel2."
}
|
and so forth and so forth.... I tried to do it like that, but I got an error when I rehashed and loaded the script.
Any suggestions? |

Obviously the code you pasted is going to throw an error since the arguments are not balanced (i.e. #channel 1 ...etc). Try
| Code: | array set messages {
#channel1 "your string here"
#channel2 "another string here"
} |
and it should perfectly work.

In Tcl there are only really string values. There are no other data types.
Numbers are strings. They are only treated as numbers when used in the context of a number.
Array element names are strings, as are array element values.
Even a list is a special type of string where any list defining characters are also stored in the string.
I think Tcl is the only language I have used that has this distinct lack of data types. It took me a long time to become comfortable with it.
