Pyre

[edit]

Basic pyre:

What is pyre?
What is an application framework?
What is a script?
What is a component?
What is a property?
What is a facility?
How is a script different from a component? How do I decide which to use?
What does pyre require of the format (input/output, etc) of my code?
What is the difference between a facility and an component?
What is a factory?
What is a .pml file? How and when is it intended to be used?
What is a .obd file? How and when is it intended to be used?
How is a .odb file different from the same file with a .py extension?
Should I write an additional python layer around my code, or should all of that go into a pyre component?

[edit]

The pyre inventory:

What goes in the inventory, versus what is a state variable?
How do I manipulate a component's inventory after the component has been instantiated?
How can I get a component to manipulate its parents inventory?
If I use a component as a facility, can I access one of the facility's methods to return a result?
In __init__, what is the preferred naming convention for the instance? for the facility?
What is the preferred naming convention for the component file versus the component class?
Where can I find out more (documentation) on what is available in the inventory?
Is it preferred to change a variable in the inventory or at the state level?
Behind the scenes: How does the Inventory class work?

[edit]

Inheritance:

Are there reserved method names within pyre, and how can I find out what they are?
My component needs to inherit from something else, can pyre handle that?
Do I have to include methods like "_defaults" if I don't use them?
What are the minimum methods I have to include to have a functional pyre component?

[edit]

Using pyre:

How do I run everything from the commandline?
Can an application/script drive another application/script?
How do I have a component use another component?
Recombinant graphs: Can two components use the same instance of a child component?
Lists & dicts don't work in pyre from the commandline, what am I doing wrong?
Can I change the wiring of a pyre application on the fly?
What goes in a script's run method versus, say, a 'greet' method?
Can I use different explicit functions within my C code as seperate pyre components, or do I have to wrap all of my code at once?
How can I replace a method within my C code if all the C code is within a single library?
How can I know where user inputs of my application come from (command line? odb? pml?)? How can I track where user inputs of subcomponents ( and subsubcomponents ... ) of my application come from?
