set of flags that it passes to the linker in order to link against a selected set of Mercury libraries (the standard libraries plus any others specified via the --ml option) in the current grade. This removes the need for using the ml script with standalone interfaces. (Which is useful on those systems that don't have a proper shell and can't use that script!) compiler/compiler_target_code.m: Add a predicate that prints out the above information. Refactor code in order to to avoid duplication between the new functionality and the existing code for invoking the linker. compiler/mercury_compile.m: compiler/options.m: Add the new option. doc/user_guide.texi: Add an entry for the new option. samples/c_interface/standalone_c/Makefile: Query the compiler directly about what flags to pass to the linker rather than using the ml script. Query the compiler about what flags to pass to the C compiler as well. (This was implemented a while ago, but this example was never updated.) Extend this example to optionally work with shared libraries.
This directory contains some example Mercury programs. hello.m "Hello World" in Mercury. cat.m An implementation of a simple version of the standard UNIX filter `cat', which just copies its input files or the standard input stream to the standard output stream. sort.m An implementation of a simple version of the standard UNIX filter `sort', which reads lines from its input files or the standard input stream, sorts them, and then writes the result to the standard output stream. calculator.m A simple four-function arithmetic calculator, with a parser written using the Definite Clause Grammar notation. calculator2.m A simple four-function arithmetic calculator, which uses the parser module in the standard library with a user-defined operator precedence table. committed_choice.m An example illustrating committed-choice nondeterminism in Mercury. interpreter.m An simple interpreter for definite logic programs. A demonstration of meta-programming in Mercury. expand_terms.m Another example meta-program, showing how to emulate Prolog's `expand_term' mechanism. e.m A small program which calculates the base of natural logarithms to however many digits you choose. It illustrates one way to achieve lazy evaluation in Mercury. Mmakefile The file used by `mmake', the Mercury Make program, to build the programs in this directory. The `solutions' sub-directory contains some examples of the use of nondeterminism, showing how a Mercury program can compute - one solution, - all solutions, or - some solutions (determined by a user-specified criteria) for a query which has more than one logically correct answer. There are also some sub-directories which contain examples of multi-module Mercury programs: diff This directory contains an implementation of a simple version of the standard UNIX utility `diff', which prints the differences between two files. c_interface This directory contains some examples of mixed Mercury/C/C++/Fortran programs using the C interface. rot13 This directory contains a few implementations of rot-13 encoding. muz This directory contains a syntax checker / type checker for the specification language Z. solver_types This directory contains an example solver type implementation and some sample applications.
