Title: exec | A | B and wait or pause execution (SOLVED!)
Post by: 80063r on May 28, 2009, 11:18:45 AM: What I really need to do is run a command-line exe and pause the template execution until the process is finished. The process completes in less than half a second. It is similar to RAWR-Designs thumbnail and preview generator.

There is no console output, but can I capture the exit code? Something like >1 is failed and 0 means success.
Also, the command line can include /M to show a small dialog box upon completion.

Or, can HFS possibly be updated to include the output of the error code. Like:

{.exec|filenameAndPath|commandLineParameters|out=#colsoleoutput|code=#errorcode.}

I'm not sure where to ask a question like this. I searched for "pause execution" and found no results.

Also, if you can give advice on this, I only want the process run if the picturename_tn.jpg file does not exist in the /thumbs subfolder. I've been working on this only for a few hours, so given time I may be able to figure it out myself. I may have to make my own thumbnail generator which I could do.

Thanks in advance for any advice.

...the out parameter...

This program, EasyThumbs or ezthumbs.exe, does not appear to support any console output. The only output I can get is to use the /M switch to display a dialog box.

When I tried the "out" parameter, I got a blank output, but the thumbnail was correctly created.

BUT, can I be assured that by using the "out" parameter that the process IS actually complete. That would be enough.

I like the program because of the many option switches for the command line.

@mars:
I tried {.WHILE|true|{: {.exec|......} :}|timeout=5.} and the exec didn't get exec'd.
According to the Wiki:
Quote
The special macros with such behaviour are: if, set, for, switch and breadcrumbs.
Is this correct?
When I removed the quoting, {: :}, it worked but the timeout didn't delay the macro execution at all.
Just for fun, I also tried "false" and it had identical results.
What is surprising to me is that, when I watched "Task Manger", I only saw one "ezthumbs.exe" process. I thought it may show many copies running. Maybe it is set for "only one instance" by default.
I ran:
Code: [Select]
{.while|true|{.exec|ezthumbs.exe|{:"C:\Users\80063r\Pictures\Screen Shots\UltraEdit_Environment_2.jpg" /D="C:\Users\80063r\Pictures\Screen Shots\thumbs" /P=_tn /W=100 /H=100 /Z=ShrinkToFit /F=Nearest /Q=70 /B=0 /C=0 /S=0 /R=0 /Log=tnlog:}.}|timeout=20.} {.set|#tn|1.} {.call|#tn.} {.focus.}and the "Run Script" dialog focused immediately and showed the "1".

I can't seem to get any delay with "while".

Code: [Select]
> exec|ezthumbs.exe|{:"C:\Users\80063r\Pictures\Screen Shots\UltraEdit_Environment_2.jpg" /D="C:\Users\80063r\Pictures\Screen Shots\thumbs" /P=_tn /W=100 /H=100 /Z=ShrinkToFit /F=Nearest /Q=70 /B=0 /C=0 /S=0 /R=0 /Log=tnlog:} < > while|true| |timeout=20 < > set|#tn|1 < > call|#tn < 1 > focus <
Also, just to be crazy, I set a variable to the value of the thumbnail and tried to compare or "cut" that. I can't get cut to work properly with any variable even with:
Code: [Select]
{.set|#tn|abcdefg} {.cut|3|4|#tn.}I get "n" as in the third character of "#tn". I tried every combination of ! # ^ % {. .} I can think of.

Setting a variable to the value of the thumbnail just seemed to mess up macro execution.

Post by: Mars on May 28, 2009, 10:56:41 PM: Forget my suggestion, I have just realized that she is in fact supposed to execute the macro ' exec ' as often as she can it during the granted lapse of time. >:(

This is the perfect example of the fact what is a bad example ;D

{.set|#x|ragnagna.}
{.WHILE|#x|{: {.add to log|RAGNAGNA.} :}|timeout=5.}

Saddened for it but even rejetto did not think of it, it will be necessary to wait for the next build.

Post by: 80063r on May 29, 2009, 01:16:58 AM: Have a look at this. I thought that quoting could be grouped. Like {:.....{:.....:}.....:}. But apparently it can't.
Wouldn't it be nice if this script would "add to log" 10 times at 1 second intervals. If quoting was grouped, then I could do what I wanted to as the first post requests.
Code: [Select]
{.focus.} {.set|#x|1.} {.set|#y|10.} {.while|#y|{:{.dec|#y.}{.set|#flag|1.}{.while|#x|{:{.if|#flag|{:{.set|#flag|0.}{.add to log|RAGNAGNA.}:}/if.}:}|timeout=1/while.}:}.}This is not what I intended.

i think that using the "out" parameter it should wait for the process to complete, or it could not give you the output!

YES! I just confirmed that using the "out=" parameter does pause the execution until the process is complete.

With this program "ezthumbs.exe", it provides no output, so the #variable after "out=" will serve as a dummy variable.

Thank you. That is what I needed to know.

By the way, my exec macro looks like this:
Code: [Select]
{.exec|ezthumbs.exe|{:"C:\Users\80063r\Pictures\Screen Shots\UltraEdit_Environment_2.jpg" /D="C:\Users\80063r\Pictures\Screen Shots\thumbs" /P=_tn /W=100 /H=100 /Z=ShrinkToFit /F=Nearest /Q=70 /B=0 /C=0 /S=0 /R=0 /Log=tnlog:}|out=#tn.}
EasyThumbs is also Freeware.

Thank you, that covers my other questions.

I will keep trying.
