    Source metafiles

    - -

    -Sometimes is useful to be able to define several entities in the same source file. This can be accomplished by using Logtalk source metafiles. Logtalk source metafiles are identified by the extension .mlgt. A metafile can be interpreted as the concatenation of source files. Logtalk compiles a source metafile by automatically splitting it into individual entity source files. In addition, two helper files for compiling and loading the extracted entity files are generated. The names of these helper files are the concatenation of the metafile name with the sufixes _load and _compile. Both helper files use the extension .lgt. For example, splitting a metafile named my_program.mlgt results in helper files named my_program_compile.mlgt and my_program_load.lgt. -

    -

    -Source metafiles may be compiled and loaded in the same way as single-entity source files by using the Logtalk built-in predicates logtalk_compile/1-2 and logtalk_load/1-2 (omitting the .mlgt file name extension). For example, assuming a metafile named my_program.mlgt, the following call: -

    -
    -    :- logtalk_compile(my_program). 
-
    -

    -results in the compilation of all extracted entity files. Likewise, the call: -

    -
    -    :- logtalk_load(my_program). 
-
    -

    -results in the compilation and loading of all extracted entity files. If compilation options are given (through the use of the predicates logtalk_compile/2 or logtalk_load/2), these will be used in the compilation and loading of each extracted entity file. -

    -

    -Currently, only limited error checking is performed during extraction of individual source files from a source metafile. The extraction process is guided by the occurrence of opening and closing entity directives, with all terms being copied to the generated files without further analysis. -

    -

    -As with source files, clauses and directives occurring before an entity opening directive are copied unchanged to the extracted entity source file. In the unlikely event that a source metafile does not contain any entity definitions, any predicate clauses and directives it might contain are copied, unchanged, to the generated loading helper file (but not to the generated compiling helper file). +Logtalk source files may contain arbitrary Prolog directives and clauses interleaved with Logtalk entity definitions. These directives and clauses will not be compiled by the Logtalk preprocessor and will be copied unchanged to the corresponding Prolog output file.

However, there are some differences between the usual implementation of Prolog debuggers and the current implementation of the Logtalk debugger that you should be aware. First, unlikely most Prolog debuggers, the Logtalk debugger is not implemented as a meta-interpreter. This translates to a different, although similar, set of debugging features with some limitations when compared with some Prolog debuggers. Second, debugging is only possible for objects compiled in debug mode. When compiling an object in this mode, Logtalk keeps each clause goal in both source form and compiled form in order to allow tracing of the goal execution. Third, implementation of spy points allows the user to specify the execution context for entering the debugger. This feature is a consequence of the encapsulation of predicates inside objects.
