String

[Lu5ck]

Hi all,

How do you add text to string? Something like insert or var + "this message" in other language.

Using append (for strings) or concat (for lists):

Code: Select all

append var "more text"
concat var "other stuffs"

Hi there,

Thanks for the answer. What if I want to add text into the center of the string or any location in the string.

Code: Select all

set test "This is just a test uh"
set test [concat [lrange $test 0 2] "OOPS" [lrange $test 3 end]]

Code: Select all

Tcl return: This is just OOPS a test uh

use lrange to grab what you want.

Errmmm.... NO!
First learn do tell the difference between lists and strings in tcl...
Add a { or such into the test-string and watch how your code falls apart...

Proper code would look something like this:

Code: Select all

set test "This is just a test uh"
set list1 [split $test]
set list2 [list "This" "is" "just" "a" "test" "uh"]
set result1 [join [concat [lrange $test1 0 2] "OOPS" [lrange $test1 3 end]]]
linsert list2 3 "OOPS"

Edit:
In order to accomplish the same result without resorting to lists, use something like this:

Code: Select all

set test "This is just a test uh"
set result [string replace $test 12 12 "OOPS "]

Hi there,

Is there a easiler way to do it if I wanted to add text infront of the string?
