A feature wish on Toplevel directives.

A feature wish on Toplevel directives.

[sejourne_kevin]

Hello,


Here an example of what is a problem to me:
.-------------------------------------------
|         Objective Caml version 3.08.3
|
| # let p = read_line()^".ml";;
| printer
| val p : string = "printer.ml"
| # #use p;;
| Wrong type of argument for directive `use'.
| #
`-------------------------------------------

Because 'p' has the type 'string', it seemed to me natural that '#use p' 
would be an equivalent to '#use "printer.ml"'. Naturally, in this cases, 
I do not want to use DynLink because all the definitions would be hidden.


regards.

Try this,

let eval s =
   let l = Lexing.from_string s in
   let ph = !Toploop.parse_toplevel_phrase l in
   assert(Toploop.execute_phrase false Format.err_formatter ph)
;;

eval (sprintf "#use \"%s\";;" p);;
