Storing metadata with PyGhidra

[bdemick]

Following on to #7343 - Is there a simple way store extra metadata with the program/project? In the past, I've used GhidraState.add/getEnvironmentVar() for this to serialize data between scripts. However, this appears to require the GhidraScript API to accomplish (as far as I can tell) and it seems like that's probably not the right route here. I've achieved the desired effect using the PropertyMapManager interface:

prop_mgr = program.getUsrPropertyManager()
string_map = prop_mgr.createStringPropertyMap("user_data")
map_addr = program.getMinAddress()
string_map.add(map_addr, "my data")

Then when using the program later, I can just get the property manager and access the data that way. This seems to work, but I'm wondering if there's a more generic approach that I'm missing. The data in this case isn't address-specific, it's just required by the API.

What are you trying to store? Is is program-specific or project-specific?

[bdemick]

Program-specific, but could probably use both. Basically metadata (can be as simple as a json string) that I can grab from a script later on to do things like configure analysis.

Here's one way to store some basic metadata in a program:

Options props = program.getOptions(Program.PROGRAM_INFO)
props.setString(optionName, value)

This will then be visible in the CodeBrowser under Help -> About <program>

This works, much cleaner than my initial approach. Thanks!
