Accessing Symbol properties from SKILL

ElectronMonkey over 10 years ago

In Allegro PCB, when I do Show Element from the GUI and select a symbol, it shows something like this:

< SYMBOL>

RefDes: R7

Properties attached to symbol definition

PROP1 = blah
PROP2 = blahblah

How do I access these properties in SKILL? I want to read and edit/set them. The properties are defined in the global dictionary.

p=axlSelectByProperty("symbol" "PROP1")

returns nil and does not select anything.

axlDBGetProperties()

never returns anything but nil.

Poking around on the command line investigating symbols and components has not revealed the desired properties.

First, I want to be able to read them, and then I want to modify/add these properties.

Any ideas on how I should be doing this?

Thanks.

As you indicated, the properties are on the symbol definition so you would need to do:

     p = axlSelectByProperty("symdef" "PROP1")

If axlSelectByProperty finds dbids it returns a list of dbids, so to look at the 1st symdef in the list

    symdef = car(p)

To get the property value

     symdef->prop->PROP1

To delete the prop off all objects found

     axlDBDeleteProp(p '("PROP1"))

To modify property with a new value on all objects found

     axlDBAddProp(p '("PROP1" "foo"))

Excellent! Thanks, fxffxf. Those seem to be the main pieces I was missing.
