Re: shell() in a separate thread with callback message at exit?
Here is an example script that does a ping. The handler includes the post-processing of the result, but you can just ignore that. function checkPing pIP ... put ping -c1 -npIP into tShellCmd put tFileName 21 after tShellCmd Thank you a lot Sarah. Your code let me discover the wait .. with messages which I have never been aware of (the old Hypercard practice?). This can actually do the job I am searching for. Also, your example raises two questions: 1.- Is there somewhere some documentation on synchronous/asynchronos parallel/threaded Transcript execution? I would like to learn about other such great features native in Transcript... 2.- I understand the shell command you wrote up to ping -c1 -n 192.168.0.1 and even the mandatory for executing the shell in a separate thread but I dont understand the 21 . Could you explain? Do you have a good MacOSX/Un*x tutorial on the shell commands?

Re: shell() in a separate thread with callback message at exit?
This is an important feature request - no? I am not sure how to do this - I have suspected you may be able to do this with some clever shell scripting - but not cracked it for things that you need results from. You can put a shell into the background using ie think, and you could look into the screen command, but the only ways I figured on doing this properly is to have a separate program running and executing the shell. This program can then talk to Rev using sockets or some other technique. On 10/03/07, Joel Guillod [EMAIL PROTECTED] wrote: What platforms are you supporting?

Hi Joel, This isn't exactly what you described, but here is how I do it. Start the shell command running in the background but directing it's output to a text file. Then have a loop to check for this text file until it appears or until a time out period has elapsed. Here is an example script that does a ping. The handler includes the post-processing of the result, but you can just ignore that. function checkPing pIP put specialFolderPath(Desktop) /ping.txt into tFileName if there is a file tFileName then delete file tFileName put ping -c1 -npIP into tShellCmd put tFileName 21 after tShellCmd get shell(tShellCmd) put 0 into timeCheck repeat 50 times wait 1 tick with messages if there is a file tFileName then put URL (file: tFileName) into tRes if tRes is empty then next repeat -- file created but no result yet put wordOffset(loss, tRes) into tWord if tWord = 0 then next repeat -- file created but result not complete put word tWord-2 of tRes into tPercent if tPercent = 0% then return true else return false end if end repeat if there is a file tFileName then delete file tFileName return false end checkPing Cheers, Sarah ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

shell() in a separate thread with callback message at exit?
How can I implement the following features: - invoque a shell command in a separate thread, i.e. a non blocking shell during execution of the command; - receive a callback message with the output and the error result when the thread exits? This would be some function similar to the load command, i.e.: shellExecute commandLine [with message callbackMessage] where The commandLine is a string or an expression that evaluates to a string. The callbackMessage is the name of a message to send after the shell exited. The callbackMessage signature would be: on callbackMessage pCmdOutput,pCmdError,pShellError where - pCmdOutput is the value returned by the shell function, i.e. the result of the sdtout commandLine, including any error messages the commandLine generates. - pCmdError is the error the command generate (sdterr under unix). - pShellError is the shell command's exit code. If I remember well the externals API allows for such threading and callback but I am not a C expert. Could anyone give me refs/pointers to a solution? I need a multiplatform solution. Thanks a lot !
