Need help: ConsoleWrite not working

[JohnJF]

Hi, I cannot get the following to work - print a text string to stdout:

ConsoleWrite("hello, world" & @CRLF)

When I run it (hello.au3) using winxp command console, nothing happens and it exits to the shell. Do I miss something?

Thanks for help! I did try to search the forum, but did not find anything to solve the issue. If it is already asked before, would appreciated the link.

You must compile the script as a command line application to see it.

if you need to test very often you can run the script in scite using F5. the the printed text will be shown in the box under the source editing box.

Thanks! Running the following and then hello.exe solves the problem:

"c:\Program Files\AutoIt3\Aut2Exe\Aut2exe.exe" /in hello.au3 /out hello.exe /console

However, just wonder why running .au3 directly on cmd console does not work. It would be nice to have that feature: have to compile the script to use ConsoleWrite is not really convenient.

A follow-up question: can you (and if so how to) specify the command line arguments when running hello.au3 in the editor (your 2nd workaround)?

You can use the following Au3Wrapper directive to run your exe as an console application:

#AutoIt3Wrapper_Change2CUI=Y
ConsoleWrite("Hello World" & @CRLF)

JohnJF,

And you can run with parameters in SciTE by pressing "Shft-F8" or by using the <View - Parameters> menu item.

But you still need to compile it and run the hello.exe, *not* hello.au3, right? I mean you cannot just add the line:

#AutoIt3Wrapper_Change2CUI=Y

and run hello.au3 and get the same result. I would prefer just have an .au3 file and run it on command line w/o any compile or other procedures. The interpreter seems not able to detect it is now running in console mode and print to stdout correctly.

Cool! This will be handy. However, I still hope some future version can support the general command line usage, Shft-F8 only allows 4 args., this is really argc/argv in C program, and will make it easy to script and prototype.

Its simple to explain as the AutoIt3.exe is compiled a GUI not a CUI.

Have you tried to compile a script as CUI and then use that script to run the script with by using this format:

Compiled.exe [/ErrorStdOut] [/AutoIt3ExecuteScript file] [params ...]

Just put multiple arguments in one box

Can you give an example how to do this - how to write the compiled.au3? I assume then you can use the compiled.exe to run any .au3 script. This sounds to me that the compiled.au3/compiled.exe is the interpreter itself, but in CUI mode.

[Jos]

Its pretty simple.

Stub Script (mystub.au3)

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_UseUpx=n
#AutoIt3Wrapper_Change2CUI=y
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
; CUI stub

Compile it.

test1.au3 script:

ConsoleWrite("hallo")

Now run this in the commandprompt:

mystub.exe /AutoIt3ExecuteScript test1.au3

Thats all,

Jos

Hi Jos, this does work for my hello.au3. However, I run into issues with script using include, eg, the following:

#include <Array.au3>

ConsoleWrite("hello, world" & @CRLF)

$length = _ArraySize( $CmdLine )

ConsoleWrite("command line array length is: " & String($length))

Func _ArraySize( $aArray )

SetError( 0 )

$index = 0

Do

$pop = _ArrayPop( $aArray )

$index = $index + 1

Until @error = 1

Return $index - 1

EndFunc

Running the above pops up an error message, complaining that "Array.au3" cannot be opened. Do you know if this can be fixed?

Should work fine when you put it in the same directory as the Autoit3.exe.

Sweet - works now! Thanks for all the help and creating AutoIt! It is really cool and I guess I will sink lots of time into it :-)
