Hi,
I look for a method to transform a list of string expression in list of
symbol expression.
An example :
I have : ( "a" "b" "c")
I would ( a b c) or ( A B C )
Thanks you in advance.

Well, you can do that with
(let ((*package* ...)) ; you want to control where these symbols get interned
(mapcar #'intern string-list))
But that's kind of a weird thing to do. So, to back up a minute, why
do you think you want to do this?

Do you have a simpler method ?!!
I look for easilier method to transform a string in symbol. I use a function
which returns the string but i need a symbol or a string without the quotes.

I meant that question in a broader sense: what are you trying to accomplish here?

I'm trying to transform a word (string) in symbol for evaluate its. For
example, i have "print" "i" (i is a variable) and i would like eval (print
i).
The read-from-string function seems very nice. I will try it.
Thank you all.

I see signs of Perlite here, with Tclite complications.

Read about READ and the reader. :) It is goo medicine.

Are you "scapegoating" for some Perl programmer? :)

Good grief. That *is* a simple method. Were you expecting
there to be a single function that does this?

Why do you need a symbol? Why can't you just use the string?
And what do you mean by "a string without the quotes"? The quotes aren't
part of the string, they're just part of the string's printed
representation. If you print it with FORMAT's ~A format control, the
quotes won't be printed.

Use MAPCAR with either INTERN, MAKE-SYMBOL, or READ-FROM-STRING, depending
on your precise needs.

I think that i going to use 'read-from-string' but i tried the make-symbol
function and i had surprised by the result.
(make-symbol "TOTO") returns #:TOTO. Why? What is it represent by '#:' ??

>(make-symbol "TOTO") returns #:TOTO. Why? What is it represent by '#:' ??
That indicates that the symbol isn't interned in any package. Read the
documentation of INTERN and MAKE-SYMBOL and compare them.

Depending on what you want, you should look at either
#'intern or #'make-symbol (the HyperSpec is your friend).
For lifting that functionality to lists, have a look at #'mapcar,
perhaps coupled with some lambda'ing.
Kind regards,
Hannah.
