Subject: Hooking up to function definition via module
Date: Tue, 18 Apr 2017 10:23:46 +0200	[thread overview]
Message-ID: <etPan.58f5cd12.2eb141f2.15fbc@MacMini.local> (raw)

Hello,
I would like to receive a callback or something else, when a function is defined. For example, I can detect setopt by wrapping bin_setopt(), like this:

    Builtin bn = (Builtin) builtintab->getnode2(builtintab, "setopt");
    bn->handlerfunc = bin_setopt2;

So in theory I can analyze setopt arguments in bin_setopt2(), record which option is being set, even if it is already set to requested state, then call original bin_setopt().

I think I cannot do something similar with function redefinition/definition, because there isn't a builtin dedicated to this, so I cannot wrap that builtin. But maybe I'm wrong?
