Would even be more awesome if it provided a function which
could be called from a custom main on top of the FancyMain.
I find e.g. custom parsing of command line arguments incredibly
useful.
Yea, the version 2.0 stuff inside cgi.d does that. You can call
`cgiMainImpl` from your own main thing (that's all the mixin does
anyway) and disaggregate it as much as you want.
I was improving that this week when the baby decided to come, so
the rest will be coming a little later. But on my copy right now
you can even break up cgiMainImpl because its implementation is:
---
void requestHandler(Cgi cgi) {
// if you call cgi.dispatcher in here, it does basically
// what the old FancyMain would do, going to a class.
}
void main(string[] args) {
alias CustomCgi = Cgi; // just normal class w/o more
custom
if(tryAddonServers(args))
return;
if(trySimulatedRequest!(requestHandler, CustomCgi)(args))
return;
RequestServer rs;
rs.listeningPort = 3000; // if you want to change default
rs.configureFromCommandLineArguments(args);
rs.handleRequests!(requestHandler, CustomCgi)(); // this
may never return
}

But I haven't pushed this live yet. Probably will write about it
in the blog next week or the week after depending on how
everything else irl goes. Still not 100% happy with it, but a big
goal with my version 2.0 implementation here is to make more
pick-and-choose customization possible while still using the
automation in the places you want that.
