Thank you for your prompt response Bill,
How exactly do I write this directive?
I dont undestand how it would be used...
Is it instead of the #macro directive???
Also the parsing of macros right now does not include the '#end' tag, it is
like a simple line directive. Do you think it would be posible to
diferentiate macros defined with a new directive (say #macrowb -a macro with
body) that assigns to its macros the property of accepting child nodes
during parse time?
Would you join me if I start developing this?
Do you think it is possible?
Do you think it is simple to do?
best regards,
Dario.
PD: Perhaps a simpler startup is to have a simple directive that catches all
its content and puts it in a string. Say:
#text into $mystr until '---end---'
here code or anything
---end---
so with this simple directive I could perform a parse on runtime and even
cache the internal representation in a hashTable according to filename and
linenumber.
Then it is just a matter of naming things or alike so to have this variable
accesible from within any VM.
What do you think?
