logtalk_load/2¶
Description¶
logtalk_load(File, Flags)
logtalk_load(Files, Flags)
Compiles to disk and then loads to memory a source file or a list
of source files using a list of compiler flags. The Logtalk source file name
extension (by default, .lgt
) can be omitted. Source file paths can be
absolute, relative to the current directory, or use library notation.
Compiler flags are represented as flag(value). This predicate can also be
used to compile Prolog source files as Logtalk source code. When no recognized
Logtalk or Prolog extension is specified, the compiler tries first to append a
Logtalk source file extension and then a Prolog source file extension.
If that fails, the compiler tries to use the file name as-is. For a
description of the available compiler flags, please see the
Compiler flags section in the User Manual.
When this predicate is called from the top-level, relative source file paths are resolved using the current working directory. When the calls are made from a source file, relative source file paths are resolved by default using the source file directory (unless a relative_to flag is passed).
Note that only the errors related to problems in the predicate argument are listed below. This predicate fails when errors are found during compilation of a source file.
Warning
The compiler flags specified in the second argument only apply to the files listed in the first argument and not to any files that those files may load or compile. Notably, if you are loading a loader file, the flags only apply to the loader file itself and not to the files loaded by it.
Modes and number of proofs¶
logtalk_load(@source_file_name, @list(compiler_flag)) - zero_or_one
logtalk_load(@list(source_file_name), @list(compiler_flag)) - zero_or_one

Examples¶
% compile and load the "list" source file in the
% current directory using default compiler flags:
| ?- logtalk_load(list, []).
% compile and load the "tree" source file in the "types"
% library directory with the source_data flag turned on:
| ?- logtalk_load(types(tree)).
% compile and load the "file_system" source file in the
% current directory with portability warnings supressed:
| ?- logtalk_load(file_system, [portability(silent)]).
