Fanp
Overview
The fanp
command line tool is used to dissemble compiled fcode. If you have a burning desire to hack the compiler or the runtime emit code, then you will find fanp
indispensable. Like many of the other command line tools you can pass a pod name, a type qname, or a slot qname:
fanp fansh fanp fansh::Main fanp fansh::Main.main
By default only high level signatures and facets are printed. Print the usage via "-?" to see various options.
Dissembling Code
The "-c" option will dump the opcodes:
// fansh::Main.main static Void main() { Shell.make.run } // disassemble it C:\>fanp -c fansh::Main.main main () -> sys::Void [const public static] [Code] 0: CallNew fansh::Shell.make() -> sys::Void 3: CallVirtual fansh::Shell.run() -> sys::Void 6: ReturnVoid [LineNumber] size=2 158
