velocimacro.library - all specified required?
I’m trying to set up a system that has some built-in (to a JAR, class path loader) macros defined (in _macros.vm) and allows the user, in their own file system loader path, to define macros.vm (without underscore prefix) to add their own.
I’m trying this:
engine.setProperty(RuntimeConstants.VM_LIBRARY, "_macros.vm,macros.vm”);
But I get errors if macros.vm is not found.
Can I make it so that velocimacro.library loaded files are optional, such that if macros.vm isn’t there all works fine? It’s giving me an error currently.
Also, when given that comma-separated list, are they loaded in that order such that a macro defined in macros.vm can override one in _macros.vm?
Thanks for your help!
Erik

Glad you figured it out. I must have been thinking of the default macros
file lookup, which used to "warn" with a big error message. I suppose it
makes sense that a specified, but missing file be treated as an error.
Though that's certainly a debatable behavior.

Thanks Nathan for the reply.
I worked around this issue by setting up a special loader that had all the (all empty but one) velocimacro’s defined, allowing one or more of them to be overridden by earlier loaders.
But yeah, it chokes if the velocimacro’s specified don’t exist, not just a warning alas.

Those errors should effectively just be warnings and not interrupt the
process. (Disclaimer: i haven't dealt with that stuff in a while)

No, sorry, no way to mark a file as optional.

Later definitions should override newer ones by default, i think. But
again, it's been a while since i worked with macros in this way.
