Hi, is there a Livecode equivalent to scanf C function? It should be the opposite of the Livecode Format function.

Hi Mario,
not sure, maybe the ASK dialog?
Code: Select all
...
ask "Please enter your name:"
put it into tUserAnswer
## user clicked CANCEL:
if tUserAnswer = EMPTY then
## or:
## if the RESULT = "cancel" then
exit to top
end if
answer "Your name is:" && tUserAnswer
...
Best
Klaus

No, the scanf equivalent shoud fill a number of variables taking the values from partes of a string according to a template (look at the "format" Livecode function to have an idea, it makes to opposite).

Maybe matchText() is what you want?

For anyone with time in their hands, this includes a list of scanf options:

Probably most efficient to write an external for this, using any of the common C libs.

Effectively matchtext() seems to be the closer function to scanf at least for what concern the result, even if it uses regex.
