[Scons-users] Get a list of emitted targets from the previous run

[Bill Deegan]

Erik,

Here's what I'd do.
It's a little hacky.
In your emitter if the flag to parse is set to parse, add all the parsed
info to your source node via source[0].attributes.pyang
Then in your action (probably actionlist), add a python action to write
that info to a file.
Make sure you add that file name as a sideeffect when parsing.

When the flag is set, you can read that file in in your emitter.

I think that should work.
If you want to interactively discuss, please hop on the discord server.

Please consider contributing the tool to scons-contrib repo?

Hope that helps.
-Bill
