Hi all,
I am playing with rtt scripts and I am hurt by 2 things.
1/ I have a "Clock Component" with a periodic activity which is awaking
Subscribers via an EventPort. Each event port have an Activity with no
period ( setActivity("Io",*0*,0,ORO_SCHED_OTHER); ) and some of these
components are trying to use scripts. As they don't have a real period the
scripting plugin is complaining with "Loading program configureNode in a
TaskContext with getPeriod() == 0. Use setPeriod(period) in order to setup
execution of scripts.". So I wonder :
_ Is it the rigth methodto awake a clocked component with a 0 period
Activity ? (I am not using SlaveActivity because I don't want the clock to
be stalled on each component, they have to run alltogether with a common
start point)
_ If this is the rigth method, Is the warning a problem ? Will I have
scripting problem due to this indirect periodicity ?
_ If all is good, do I have a mean to deactivate this warning ?
2/ My components automatically load scripts during the configure phase. If a
component miss its configure after having successfully loaded all the its
scripts, I can't call the configure once again since It will try to reload
the scripts and will fail because a program with the same name is already
existing. My problem is that I know which scripts I have loaded (xxx.ops)
but I don't know which programs are in it. Do I have a mean to check the
second time I do a configure if the script was successfully loaded ?

This is certainly allowed.

Well, it's just hard to predict where your script will end up (ie how far it
gets in one trigger()) in a non periodic component. Each time the script
logic does not find an immediate continuation branch (even maybe due to a bug),
the script will stall and wait for the next execution.

We can add a property to that scripting service to disable it (nice exercise
in RTT programming :-D ) You should still be careful not to assume too much on
when your script will 'pause'.

You can check for program names, but not for files. In case you use scripted
deployment, you could load the scripts from there too, and then call
configure() on the component.

Here is a try, it is not very nice, but anyway it a base you can critizise,
especially on naming. I "stupidly" addProperty to the scripting interface
but this doesn't seems to work (or I don't know how to check it with the
taskbrowser).
I there other pieces of RTT code doing similar job I could copy ?

scripting.propWarnZeroPeriodScripts = false
can be called from the taskbrowser (after you .provide scripting), or
from a script you're loading.
> I there other pieces of RTT code doing similar job I could copy ?
It should work. Could you rename it to 'ZeroPeriodWarning' and default
to true in the constructor ?

Yes it does, I didn't tryied it directly. In fact what I did was to hit tab
after writing "scripting.p". It doesn't show this property is existing. Did
I do something wrong ? Is a an expected behavior ?
How a user could find this property ?
BTW should I write any documentation ?

I meant to do this, it is was testing code I did not switched back. I'll do
a patch after you answered for the "Z".
Would you like a trac ticket ?

It was a bug in the taskbrowser. I pushed a fix to toolchain-2.3.
Could you test that ?

You need to document it as well with the .doc("...") function of addProperty.

You should update the warning message with a reference to
'scripting.ZeroPeriodWarning' that should do it I guess, in
combination with the .doc().

Patch on mailinglist is fine. we're having already the discussion here :-)

I am just interested in knowning if the Program is finished without errors.
Is that yourt point, I'll never know if it is blocked on an Operation or if
the script end ? Maybe I should use a variable that I set to true at the end
of the program.

Each program Foo { } is available as a service. So you can query if it
is 'Foo.inError()' or 'Foo.isRunning()' But you could also set a
success/error flag as easily.

This use is for my configureHook. Isn't it simpler to use runScript in C++

The only way is to throw a C++ exception from C++ code. You can throw
anything, like 'throw -1', this will trigger the Error state.
runScript() will stop and return false if such an exception is caught.

Could we add a throwError Operation in the scripting plugin so that script

Yes. I do prefer a 'service' function above an extension to the
language/parsers.
I would just abbreviate it to 'throw' (ie scripting.throw("foo reason") )
For this function, we could create an exception class that takes a
string argument, giving some information about the reason why we're
throwing.

$ rosrun ocl deployer-gnulinux
Switched to : Deployer
This console reader allows you to browse and manipulate TaskContexts.
You can type in an operation, expression, create or change variables.
(type 'help' for instructions and 'ls' for context info)
TAB completion and HISTORY is available ('bash' like)
Deployer [S]> .provide scripting
Trying to locate service 'scripting'...
Service 'scripting' loaded in Deployer
Deployer [S]> scripting.
scripting.activateStateMachine scripting.getProgramStatus scripting.getStateMachineStatus scripting.inStateMachineError scripting.isStateMachineRunning scripting.pauseStateMachine scripting.stepProgram
scripting.deactivateStateMachine scripting.getProgramStatusStr scripting.getStateMachineStatusStr scripting.inStateMachineState scripting.loadProgramText scripting.requestStateMachineState scripting.stopProgram
scripting.eval scripting.getProgramText scripting.getStateMachineText scripting.isProgramPaused scripting.loadPrograms scripting.resetStateMachine scripting.stopStateMachine
scripting.execute scripting.getStateMachineLine scripting.hasProgram scripting.isProgramRunning scripting.loadStateMachineText scripting.runScript scripting.unloadProgram

Deployer [S]> scripting.ZeroPeriodWarning
= true
Deployer [S]> scripting.ZeroPeriodWarning =false
= false
Deployer [S]>
Here it does... It did not occur in the TAB completion (have a fix for that) but from the moment you type the capital 'Z', it completes it further.
