Basic Makefile Commands

The following are some of the commands that may be used in an m3makefile. They declare their arguments as private: visible only within the current package. To declare an interface or module as public, use the capitalized version (e.g., Interface(), Implementation(), etc.).

interface(X) / generic_interface(X)

Declares that the file X.i3 (or X.ig for generics) contains an interface. All interface files that you create must appear in interface commands. Leave the .i3/.ig extension off.

implementation(X) / generic_implementation(X)

Declares that the file X.m3 (or X.mg for generics) contains a module. All module files that you create must appear in implementation commands. Leave the .m3/.mg extension off.

module("X") / generic_module("X")

Declares X.i3 and X.m3 with one command (X.ig and X.mg for generics).

program(<name>)

An m3makefile generally has one program command. This specifies what to name the program executable.

library(<name>)

If the m3makefile describes a collection of interfaces and modules that are designed to be a library instead of a program, use this command instead of program().

import(<lib>)

This command specifies packages to be imported. The libm3 package must be included in all Modula-3 programs with the import command.
