HowTo Variable Expansion ?

Recommended Posts

EdDyreen

In CMD;

@Echo off &SetLocal EnableExtensions EnableDelayedExpansion

set "VAR=echo.Hello there ^! 1 &1 = 2"
::
%VAR%

OUTPUT;

Hello there ! 1 &1 = 2

In AU3;

AutoItSetOption ( 'ExpandVarStrings' , 1 )
;
$VAR = MsgBox ( 0, '', 'Hello there ! 1 &1 = 2' )
;
$VAR$

OUTPUT;

ERROR: syntax error (illegal character)

$VAR$

In AU3;

AutoItSetOption ( 'ExpandVarStrings' , 1 )
;
$VAR = MsgBox ( 0, '', 'ok' )
;
$VAR

OUTPUT;

ERROR: syntax error

$VAR

How do I set a variable and then execute it as if it were a command ?

Don't mean the obvious solution;

MsgBox ( 0, '', $VAR )

Otherwise the code would grow very looong, when I start doing much more complex things

Also a related problem

in CMD;

set "Debug.Define=if defined Debug.Sub"

:ThisFunction
::(
   set "Debug.Sub=ThisFunction"

   %Debug.Define% echo.Debugging !Debug.Sub!
...

I am stumbled how can I do that simply in AU3 &then I mean the %Debug.Define% part

Am I really going to have to write a complete function for something that simply in CMD ???

This is in a nutshell how it works:

$var = " I am text"
MsgBox(0,"Debug: doesn't show its content","var contains: $var$ ")
AutoItSetOption ( 'ExpandVarStrings' , 1 )
MsgBox(0,"Debug: Show content","var contains: $var$ ")
; -or -
MsgBox(0,"Debug","var contains:" & $var)

So u say IT IS NOT POSSIBLE to store a command inside a variable &then using the variable like it were a command ?

like:

$VAR = msgbox ( 0, '', 'hello there' )

;

$VAR$

AHA so there it had been hiding :D

Searched the help over and over &didn't find it

Maybe they should add this to FAQ in HELP for COMMAND.COM, CMD.EXE users

That would really help

Can't thank u enough for such an easy solution ;)

Why do you need something like this?

I am yet to write my first script using Execute() (only Obfuscator is using it for making statements unreadble)

Can you give me a simple example where you want to use this for?

But now I have another problem

$VAR = "msgbox ( 0, '', 'hello there' )"
Execute($VAR)

Works

$VAR = "if 1 = 1 Then msgbox ( 0, '', 'hello there' )"
Execute($VAR)

Does not work ?? :D

Try answering my question first so I understand what you want to do, because I have the feeling you are heading down the wrong path here.

I finished a sjablon in CMD language that I can load everytime when I want to write an APP

This sjablon holds all the functions I would ever need

So I copy the sjablon rename it to my new APP &start from there

for example when i need networking support I do:

sjablon code init

   ...

sjablon /code init

app code init

   ...set /a Sjablon.NET = 2 &:: 0 = Essential, 1 = Local, 2 = Network...

app /code init

sjablon code main

   ...

sjablon /code main

app code main

   .. my actiual program ...

app /code main

sjablon code exit

   ...

sjablon /code exit

The sjablon will detect i want to connect to my server &it will do so before the APP starts

This is an example of a typical sjablon function in CMD to copy a file

    EndLocal

    set /a ModeColState = %ModeColState%

    set /a ERR = %ERR%
)
::
goto :eof ()
::)

You then call from your app for example like this

%XCopy.STABLE% /FullPathFile.SOURCE: FullPathFile.SOURCE /FullPathFile.TARGET: FullPathFile.SOURCE /Show_BIG /Show_OK /Halt_ERR

Here comes the cool part

set "Debug.Sub=:XCopy.STABLE"

%XCopy.STABLE% /FullPathFile.SOURCE: FullPathFile.SOURCE /FullPathFile.TARGET: FullPathFile.SOURCE /Show_BIG /Show_OK /Halt_ERR

echo.endoftest
pause
exit

This will make the sjablon print debug information ONLY for the calling function since %Debug.Equals% is

for %%! in ( Debug.Equals ) do          set "%%!=if defined Debug.Sub call set "Ó=%%Sub.^^^!Sub.Depth^^^!.Name%%" ^&if /i ["^^^!Debug.Sub^^^!"] == ["^^^!Ó^^^!"]"

That means that ONLY if Debug.Sub=:XCopy.STABLE AND !Sub.%Sub.Depth%.Name!=:XCopy.STABLE :DEBUG () will run :

Of course u will have to remove the %debug% comments in :XCopy.STABLE () otherwise it won't work.

the comments are there to speed up CMD exec a little while I am not debugging a none compiled sjablon

So the reason I want it is because i am doing a language conversion battle

I WAN'T EVERY CMD FUNCTION TO EXIST AS AU3 YEP THAT's RIGHT :D

&I want to minimize the amount of rewriting I have to do !

Why ?

I have 514961 characters inside my sjablon, it is incredibly huge since it tries to catch any possible error at any time

But it does about everything i want it to in CMD, it is written to handle multiple instances

It can even spawn a new instance of itself to execute a sub Function so doing multiprocessing :huggles:

Now I wan't to update to AU3 &VBS since CMD is SLOW, WEAK, HARD to DEBUG &no fun to program in

I have been looking for an editor that can syntax check a CMD script for ages without succes :D

So in short I am converting from the CMD language

I wan't to stick close to the CMD code I already have since I am

reading a CMD function

writing an AU3 equivalent etc..

reading a CMD line,

writing an AU3 equivalent

This is why %expandable_var% is such a problem for me

if I can't find a good solution I'll have to go a long way to get to the same poin't.

I know I can avoid %expandable_var% but hey, it's already there... :D

In CMD you typically set a variable to a command or series of commands that can itself also contain variables that need expansion

example:

@echo off &SetLocal EnableExtensions EnableDelayedExpansion

for %%? in ( Slash.Rem.Last ) do set "%%?=set "%%^^!=^^^!%%^^!^^^!\###" &set "%%^^!=^^^!%%^^!:\\###=^^^!" &set "%%^^!=^^^!%%^^!:\###=^^^!" "

set "VAR=C:\Path\"

for %%! in ( VAR ) do %Slash.Rem.Last% %()%

this will give u VAR=C:\Path

Just back... I am not constantly online :huggles:

I need to let this sink in before trying to answer as its a little more complex than expected.

I am used to the good old dos prompt and batch files but not to a level that you are at with these Sjablon/templates.

I knew you are from Belgium already.

Saw some Dutch in your dos stuff so checked from which surrounding you were coming.:

Looking at the stuff you posted it seems to me you need to do a total rewrite of all these template functions in AutoIt3 without trying to stick to the DOS type syntax, because what else is the purpose of doing this in AutoIt3?

I have yet to figure out what the purpose is of doing this in AutoIt3

I have been doubting for a long time what language to convert my sjablon to since my main problem with the

windows terminal always has been execution speed, syntax checking &easy debugging

I considered VBS 6 since it does a syntax check when the file is loaded &has great execution speeds

I also considered C++ since when you master it you won't need anythin else

In C you really can do everything :huggles:

However i chose AU3 since it's a great tutor for API COM etc.., very popular, FREEEEE &easy to learn.

I also chose it since CMD &VBS is soon to be replaced by PowerShell

When I found out about PowerShell my first thought was 'O great, yet ANOTHER script language !'

Like we don't have enough already.

I try to avoid having to learn PowerShell :D

Eventiually i like to have sjablon's for:

BAT, CMD, VBS older Windows OSes

AU3 Windows OSes

C++ Any OS

C++ is my goal but AU3 seems like a good inbetween to master

When I find time I will post my sjablon's for these languages on me future website

For others to learn &learn from others :D

Well see ya &happy programming :

Hi.

Either use the statement where you need it:

; $VAR = "msgbox ( 0, '', 'hello there' )"
; Execute($VAR)
msgbox ( 0, '', 'hello there' )

... or, if there are several places in your code, where you need this statement, wrap it into a fuction:

MyFunc()

Func MyFunc()
if 1 = 1 Then msgbox ( 0, '', 'hello there' )
endfunc

Regards, Rudi.
