Modules

Name Spaces

A single-level global name space is available for the names of atoms. An atom name p can be qualified with a module name m. The resulting qualified atom name m.p can be referred to globally.

Currently, no syntax exists to prohibit a programmer from writing arbitrary qualified names, and, moreover, no syntax exists to abbreviate the module name part of 'exported' names.

Compile-Time Module Loading

Syntax

Definition
   { module(modulename), Process } 
Use
   modulename.Atom

Membranes that contain module uses will be supplied with the copies of the rules specified in the corresponding module definitions.

Example

{ module(acc),
     acc.add(A),   acc.value(N) :- acc.value(A+N).
     acc.get(Res), acc.value(N) :- int(N) | Res=N, acc.value(N).
     acc.new                    :- acc.value(0) }.
{ acc.new, acc.add(3), acc.add(4), acc.get(N) }

Link-Time Module Loading

Link-time module lookup is performed when the source file does not contain the definition of a referred module. When module m needs to be looked up, the file ${LMNTAL_ROOT}/lmntal_lib/m.lmn is loaded, compiled and linked before the execution of the user program starts, where ${LMNTAL_ROOT} is the directory lmntal.jar is located at.
