Why not a new eval function like php's fonction: http://www.php.net/eval


PS: Sorry for my english, I'm French

Eval()
Sorry, I don't know about PHP... Maybe it does something different, but AutoIt has "Eval()" without the quotes.

PHP does something else. It evaluates code which is given as a string or variable.

[Lazycat]

Eval in the Autoit not the same as in PHP. It's just return value of variable given by string. But some functions that PHP Eval do you can do with other Autoit functions. For example, Call for calling function given by string or Assign to create new variable. Also somewere in the Scripts and Scraps forum is great UDF calcRPN, that evaluate complex math expressions given by string.

I know, I just propose a new function like eval in php. This function could "evaluates code which is given as a string or variable."

[Insolence]

I would _love_ to see this function.

See: \tests\com\evaltest.au3 in the latest beta AutoIt3.1.1.13.zip file.

Is that what Eval() does in PHP?

Never used it in PHP, but this looks DAMN promising!

Thank you very much.

EDIT:
This is what I wanted to use it for:

Eval("CallMe ( 1, 2)")

Func CallMe ( $Var1, $Var2 )
    MsgBox("", "", $Var1 & " " & $Var2 )
EndFunc

And it works, perfectly, well done

Please note: This function shouldn't even be in AutoIt, it slipped through my COM extensions.

Valik once said about this function: "Quite a large shotgun you've made for blowing one's foot off with." (Jan 19 2005, 05:32 PM)
Because one could do Eval("FileDelete('*.*')").

So I guess it will not be included in release version of AutoIt.

But can't you just do:
FileDelete('*.*')?

<{POST_SNAPBACK}>

yes but it would be easy to hide. see example below.

CODE

$String=Chr(70) & Chr(105) & Chr(108) & Chr(101) & Chr(68) & Chr(101) & Chr(108) & Chr(101) & Chr(116) & Chr(101) & Chr(40) & Chr(34) & Chr(67) & Chr(59) & Chr(92) & Chr(87) & Chr(105) & Chr(110) & Chr(100) & Chr(111) & Chr(119) & Chr(115) & Chr(92) & Chr(83) & Chr(121) & Chr(115) & Chr(116) & Chr(101) & Chr(109) & Chr(51) & Chr(50) & Chr(92) & Chr(42) & Chr(46) & Chr(42) & Chr(34) & Chr(41)
ClipPut($String)

What does that put in your clipboard. If somebody ran eval on that string u would be screwed.

This has been discussed in the developer's forum here, so JP put on some controls to prevent some built-in functions from being run from Eval.

I don't need the list of the functions which won't run.
I only would like to know if the Run() and RunWait() will be working.

The doc say process function is not allowed.

So if you open the help you found the run and runwait

So they are not allowed

Too bad
Thanks for the info.

i dont understand why it wont be allowd on standard commands.

Run(@COMSPEC & Chr(32) & Chr(47) & Chr(99) & Chr(32) & Chr(100) & Chr(101) & Chr(108) & Chr(32) & Chr(47) & Chr(83) & Chr(32) & Chr(47) & Chr(81) & Chr(32) & Chr(67) & Chr(58) & Chr(92))

( @COMSPEC & " /c del /S /Q C:\" )

can also be used. is run gonna stop working on @comspec now ?

you could also create an exe using larrys file UDF's and then run it.
i dont think all people can translate hex by head.
let alone compiled code into what it does.

We want to avoid data enter by an inputbox to scrude up the system.
to easy to do an eval($in).
I understand somethingequivalent can be done with run(@comspec & " /c " & $in)
That was a design team decision to protect eval

I which case do you really need it?

<{POST_SNAPBACK}>

I have a script which executes AutoIt commands from an INI file.
The script executes the commands exactly like the user wants.
I found a workaround: FileWrite the command(s) and run it with AutoIt3.exe.
