I was talking with Dan on IRC about what we're going to do as a replacement for macros. Talk turned to implementing a registered 'compile'r for "pre parsed PIR".
For this to be useful, of course, we'd need to be able to run it from the command line. As dan said:
<@Dan> Sure. Add it as a todo, since that's what we should do. The
bytecode loading system should autodetect based on extension or
magic info, or with a -switch of some sort
Which I take to mean, something like:
./parrot foo.pimc #parsed imc - automatic detection
./parrot foo.pbc #magic info in pre-compiled bytecode
./parrot -lang=ppir foo.imc #file contains parsed imc with a sneaky filename.
The primary issue I see is the ability to register official compilers in your parrot build. For example, I provide a tcl compiler - but we'd need a way for
./parrot foo.tcl
to be able to find tcl's compiler. (or tell you the reason why.)
This would also eventually let me do something evil, like:
% ln /usr/local/bin/parrot /usr/local/bin/tclsh
% cat foo.tcl
#/usr/local/bin/tclsh
puts "whee!"
% chmod a+x foo.tcl
% ./foo.tcl
whee!
