Running an Eagle script to add to a library

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am sometimes unable to run an Eagle script to update an existing library.  I have to run it on a new empty library.  I gets errors about layers not being available.  I'm not sure what the context is that leads to this working sometimes and sometimes not.  Maybe others have seen it and know.

	I know that layers are called out at the top of every script file. If those don't match to the layers of the library, ya I could see it having a problem. Not much I can do about it though other than continue to generate a script file per your requested layers.

	I've found too that if you run the script into a new, empty library, these errors will not happen. What seems to matter is what type of object is open in the library while the script is executed. If a package is open, then the script will always work. More accurately, if the library is not empty, then a device or symbol could be active and the package script might generate errors. If a package is being edited in the library and the script is run, it will work. So, while an empty library will work, it's more to do with executing the script only in the context of editing a package in the library.
