The default value is false; it can be set to true with the -quietdec command line option; see Section 3. When quotation is false the default , the backquote character is an ordinary symbol which can be used in ML symbolic identifiers. If a non-zero integer is returned, this must indicate that the operating system has failed to execute the command. The file must be in the current directory or in a directory on the loadPath list. A file loaded by use may, in turn, evaluate calls to use.

Command-line option -valuepoly sets valuepoly to true the default , whereas option -imptypes sets valuepoly to false; see Sections 3. The printed signature follows the syntax of Moscow ML signatures, so the output of compile "U. The default value is false.

The response provides much information about the declaration. It is worth learning how to interpret this information. A compilation unit consists of an implementation file unitid. A unit must be compiled in one of two modes: Structure mode: File A. Structure-mode units are backwards compatible with the simple structures used in Moscow ML version 1. Hence old Moscow ML programs can be compiled in structure mode with no changes. To compile a unit in structure mode, use the function compileStructure see Section 3.

Toplevel mode: File A. To compile a unit in toplevel mode, use the function compileToplevel see Section 3. The implementation file and the interface file if any of a unit must be compiled in the same mode. The precise syntax of structure-mode units and toplevel-mode units is given in the Moscow ML Language Overview [9]. A programming project may consist of a mixture of structure-mode and toplevel-mode compilation units.

See the example in Section 8. Compiling a unit implementation A. In addition, if there is no correspond interface A. Only the compiled unit interface A. Thus the following file name extensions have a special meaning: Extension Contents. The linker will automatically link in any required bytecode files into mosmlout. Compiled units can be loaded into the interactive system mosml using the primitives load and loadOne; see Sec- tion 3.

Loading a unit makes the entities declared by the unit accessible to subsequent declarations in the interactive system. For instance, file A. By contrast, in Moscow ML,. More precisely, Moscow ML expects file A. Thus it may be necessary to rename A. Under MS Windows, file names are not truly case sensitive. Since file names are used as unit names, this may cause problems.

Hence a unit which resides in file commands. The file unitid. When the unit interface is present, it is called the explicit signature to distinguish it from the signature inferred when elaborating the unit implementation. When present, the explicit signature must be matched by the implementation, and only those identifiers specified in the signature are visible outside the unit. More generally, when a compilation unit depends on a number of other compilation units "unitid1 ",. There must be no corresponding explicit signature file U.

Note that the file name, signature name, and structure name must be the same. When the unit interface is present, the unit implementation must implement ev- erything specified in the unit interface, and only those identifiers specified in the interface are visible outside the unit. It is considered a mistake for the implementation to declare more identifiers than specified in the interface or for the implementation to declare an identifier as a constructor or exception, but the interface to specify that identifier as an ordinary value: a warning is issued in these cases.

If there is no unitid. More generally, when a toplevel compilation unit depends on a number of other compilation units "unitid1 ",. It consists of two structure-mode units, Expr and Reduce and two toplevel-mode units, Evaluate and Test. File Expr. However, when modifying a program consisting of several units, it suffices to recompile just those units that have changed, and those units that depend on units that have changed.

Moreover, compilation uses only the interfaces of other units, so it suffices to recompile just those units that depend on unit interfaces that have changed. Thus if Expr. Similarly, if Reduce. The next section explains recompilation management using mosmldep and make. Consider the example program in Section 8 consisting of the four units Expr, Reduce, Evaluate and Test.

Edit the Makefile so that the names of the compiled unit implementation files Expr. Compute the dependencies among the files by executing: make depend 4. Recompile all those files which have not yet been compiled, or which have been modified but not yet recompiled, or which depend on modified files, by executing: make Step 4 must be repeated whenever you have modified a component of the program system.

Step 3 need only be repeated if the inter-dependencies of some components change, or if you add or remove an explicit signature file. Steps 2 and 1 need only be repeated when you add, delete or change the mode of an entire unit in the program system. Unfortunately, this means that mosmldep will generally create an inefficient Makefile, containing more dependencies than are actually in your source files.

However, it still saves some recompilation which is cheap in Moscow ML anyway and is more convenient than hand-crafting the Makefile. We hope to improve on this situation in the future, but computing dependencies for full Standard ML programs is known to be difficult. Unfortunately, this process only works for programs containing just structure-mode units, that themselves contain only flat structures, but no functors or sub-structures.

New in version 2.10.1 of Moscow ML

This is the behaviour of mosmldep in releases of Moscow ML prior to 2. It compiles units and links programs, and can turn them into standalone executable bytecode files.

The batch compiler can be invoked from a Makefile see Section 9 , which simplifies the re compilation of large programs considerably. It accepts several types of arguments: source files for unit interfaces, source files for unit implementations, compiled unit interfaces which are added to the compilation context , and compiled unit implementations which are added to the linked executable. An argument ending in. Given a file U. It also produces an inferred interface file U.

The contents of that compilation unit are added to the compilation context of the remaining source files. Such files are linked together, along with the compiled unit implementations obtained by compiling. The linker automatically includes any additional bytecode files required by the files specified on the command line; option -i makes it report all the files that were linked.

The linker issues a warning if a file B is required by a file A that precedes B in the command line. At run-time, the top-level declarations of the files are evaluated in the order in which the files were linked; in the absence of any warning, this is the order of the. The linker and the load function in the interactive toplevel ensure probabilistically type-safe linking, so it is virtually impossible to cause the system to create a type-unsafe program. The output of the linking phase is a file containing compiled code that can be executed by the runtime system camlrunm. If mosmlout is the name of the file produced by the linking phase with option -o mosmlout , the command mosmlout arg1 arg Executing the code means executing the toplevel declarations of all the bytecode files involved, in the order in which they were linked.

The list of command-line arguments arg Hence, an output file named mosmlout. The executable invokes the camlrunm runtime system to interpret the bytecode. As a consequence, this is not a standalone executable: it still requires camlrt. Unix: The output file produced by the linking phase is directly executable unless the -noheader option is used. It automatically invokes the camlrunm runtime system, either using a tiny executable prepended to the linked byte- code file, or using the Unix incantation!

To create a true stand-alone executable, use mosmlc option -standalone. Suppresses the linking phase of the compilation. Source code files are turned into compiled files. This option is useful for compiling separate units. File names in response-file are separated by blanks spaces, tabs, newlines and must end either in.
