All of the pieces have been sitting around for years.
Added several debug CLI commands:
"define <variable-name> <value>"
"undefine <variable-name>"
"show macro [noeval]"
"echo <whatever>"
Macros may refer to other macros. To defer evaluation:
"define foo \$(bar)" or some such.
The macro evaluator is not smart about "define foo \$(foo)" or more
complicated circular definitions, so don't do that.
Environment variables are available, simply use $<name-of-environment-vbl>
The macro expander has a table of (overrideable) builtin names, which
are evaluated by calling functions.
Simple example:
echo $USER
define ip1 192.168.1.1/24
define ip2 192.168.2.1/24
loop create
loop create
set int ip address loop0 $ip1
set int ip address loop1 $ip2
show int addr
show macro
undefine ip1
undefine ip2
