We can define a new category in the same way we write Prolog code: by using a text editor. Each category (object or protocol) we define should be contained in its own text file. It is recommended that this text file be named after the category. By default, all Logtalk source files use the extension <code>.lgt</code> but this is optional and can be set in the configuration files. Compiled source files (by the Logtalk pre-processor) have, by default, a <code>.pl</code> extension. Again, this can be set to match the needs of a particular Prolog compiler in the corresponding configuration file. For instance, we may define a category named <code>documenting</code> and save it in a <code>documenting.lgt</code> source file that will be compiled to a <code>documenting.pl</code> Prolog file.

In general, Logtalk does not verify if a user predicate call/return arguments comply with the declared modes. On the other hand, Logtalk built-in predicates, built-in methods and message sending control structures are carefully checked for calling mode errors.

Logtalk error handling strongly depends on the ISO compliance of the chosen Prolog compiler. For instance, the error terms that are generated by some Logtalk built-in predicates assume that the Prolog built-ins behave as defined in the ISO standard regarding error conditions. In particular, if your Prolog compiler does not support a <code>read_term/3</code> built-in predicate compliant with the ISO Prolog Standard definition, then the current version of the Logtalk pre-processor will not be able to detect misspell variables in your source code.

<p>
We can define a new protocol in the same way we write Prolog code: by using a text editor. Each protocol (object or category) we define should be contained in its own text file. It is recommended that this text file be named after the protocol. By default, all Logtalk source files use the extension <code>.lgt</code> but this is optional and can be set in the configuration files. Compiled source files (by the Logtalk pre-processor) have, by default, a <code>.pl</code> extension. Again, this can be set to match the needs of a particular Prolog compiler in the corresponding configuration file. For example, we may define a protocol named <code>listp</code> and save it in a <code>listp.lgt</code> source file that will be compiled to a <code>listp.pl</code> Prolog file.

Protocol names must be atoms. Objects, categories and protocols share the same name space: we can not have a protocol with the same name as an object or a category.
