Re: [Pythoncad-developer] Added command line support

[Matteo B. <mat...@bo...>]

Hi Gertwin,

I sow your command line and it working well .. no bugs found ..
Could we implement a Multi text viewer where pythoncad put the output 
If the command succeed say .. "o boy ..  well done :-)"
> The idea is that every module can register commands that it can
handle.
I like this idea, but I wold like that the interpret stay under kernel
(pycadapplication)

I had made some modification at the pythoncad structure ..

now the main api file is not pycadkernel but pycadapplication ...

I made this change to support the new command class  ..
This class have not the some functionality of your and is not intend to
replace you class .. it's a generic api file in witch all the gui
interface are interfaced ..

This class will provide hight level functionality to perform drawing
operation.
for now I have implemented only the getCommand method ..
this method give to you the command object so you can fill it with the
needed value and perform the applyCommand method to apply the command..

The following line will sow to you an exsample.

cObject=pyCadApplication.getCommand("segment")

for iv in cObject:  #<<-- Loop for all the needed value
    try:
        raise iv(None) #<<-- Raise the exception of the needed value
    except ExcPoint: #<<-- if it's a point came here 
        cObject[iv]=self.imputPoint()   #<<--This is my io text imput
But could be a function that ask to the user to pick a
point                   
    except ExcLenght:
        cObject[iv]=self.inputMsg("Insert A
Distance/Radius")            
    except ExcAngle:
        cObject[iv]=self.inputMsg("Insert An angle")            
    except:
       print "Bad error !!"
       raise 
else:
   cObject.applyCommand() #<<-- applay the command if all the data are
right.

you can find a working test if you run the test_kernel.py 

I intend to provide all the drawing command with this method ..


Let me know what you are thinking about it..
I think that your function Parser should be part of the pycadapplication
and not part of the interface ..so let me know if you fill the some

At this stage there is a lot of code written ..so for my point of view
we have to make a class diagram and start to discuss at the new class
structure ..so our work can be more profitable.


Regards,
Matteo
