[alicebot-general] ALICE Launching Programs

[mehri]

If you write a wrapper.exe of some type I'd then put it in a srai for exception handling:

<srai>wrapper call <system>wrapper.exe command.exe</system></srai>

And have the wrapper.exe return specific codes or strings for errors 

For example:

<pattern>wrapper call 401*</pattern>
<template>I am sorry, but system call <star/> cannot be found</template>

<pattern>wrapper call 403 * </pattern>
<template>The program <star/> has timed out</template>


<pattern>wrapper call 404 * </pattern>
<template><star/></template>

You could even use the <set> to set that the last system call was a success or not.

One precaution you should consider in any real-world time-critical
application using the <system> command, is that AIML has no mechanism
for exception handling.  So, if your command.exe runs forever, or
causes a crash, there is no way for AIML to recover.  It is therefore
prudent to write a wrapper.exe to handle such unforseen circumstances
and use the <system> command to call the wrapper.exe program, rather
than the application directly, unless you have a lot of confidence
that the program you are calling will terminate normally in a timely
fashion.
