Thanks Jesse, that's a great post. I wish I had found it when I started.
I wonder why its not higher on a google of "bash loadable builtin". It
would have saved me a lot of time figuring out how some of the internals
work like creating variables and understanding the global vs in-function
states.
Are there any resources available for understanding the bash internals
more?
Is this an appropriate place to ask questions on that or is there better
place for that?
Currently I am trying to figure out how to properly create a nameref
var. I specified the att_nameref attribute to make_local_variable but
when I examine the variable back in the script it is a simple variable
and not a nameref. I see specific functions in variables.h for creating
arrays but not one for namerefs.
in builtin..
// local -n this="$oid"
SHELL_VAR* this=make_local_variable("this",att_nameref);
this = bind_variable_value(this, pObj->vThis->name, 0);
..then in script...
declare -p this
..output..
declare -- this="myObj"

Question 3: what is the best practice for maintaining loadable builtins?
Can anyone suggest an existing loadable builtin project that I could
model mine after?
I don't have too much advice on best practices, but I did write a blog post
on writing builtins, along with some sample code, which you may find
helpful.
