Logtalk - Object oriented extension to Prolog

Release 2.16.0

Upgrading from Logtalk 1.x
|
|
==========================
|
|
|
|
Logtalk 2.x is not compatible with programs written for version 1.x.
|
|
However, you should be able to translate most programs to make them
|
|
run under this new version. Most of the examples provided with previous
|
|
versions have been rewritten to run under version 2.x. Use them as
|
|
translation examples.
|
|
|
|
|
|
Upgrading from a previous Logtalk 2.x version
|
|
=============================================
|
|
|
|
If your Logtalk programs depend on some of the example files, it is
|
|
advisable that you check your code against the new version before
|
|
throwing away the older release.
|
|
|
|
Logtalk source files will need to be recompiled because of the changes
|
|
done in the version 2.5.0 to improve message sending performance.
|
|
|
|
Logtalk version 2.7.0 provides the first cut of the Logtalk standard library.
|
|
Most examples have been rewritten to take advantage of the library.
|
|
|
|
Logtalk version 2.8.0 introduces a small change on the logtalk_compile/1-2
|
|
and logtalk_load/1-2 predicates that may imply updating your loader utility
|
|
files: the first argument is now always a list of entities even if we want
|
|
to compile or load a single entity.
|
|
|
|
Logtalk version 2.9.0 changes compiled code functors postfixes from "_sdcl"
|
|
and "_sdef" to "_idcl" and "_idef", implying recompilation of all objects,
|
|
protocols, and categories.
|
|
|
|
Logtalk version 2.10.0 changes some of the semantics of object dynamic
|
|
predicates. See the release notes for a description of the changes.
|
|
|
|
Logtalk version 2.14.4 removes the definition of the deprecated built-in
|
|
predicate logtalk_version/3 (use current_logtalk_flag/3 instead).
|
|
|
|
Logtalk version 2.14.5 changes compiled code in order to correct a bug
|
|
where sending messages such as true/0 to an unknown object will succeeded
|
|
instead of throwing the expected exception, implying recompilation of all
|
|
objects, protocols, and categories.
|
|
|
|
Logtalk version 2.14.7 changes compiled code in order to optimize the
|
|
code generated by the compilation of dynamic predicate clauses.
|
|
|
|
Logtalk version 2.15.0 changes the "authors" key in the directive info/1 to
|
|
"author". All the XSLT, DTD, and XSD files have been update to conform to
|
|
this change. If you use the directive info/1 in your programs, you will need
|
|
to apply this change to take advantage of automatic generation of documenting
|
|
files.
|
|
|
|
Logtalk version 2.15.3 changes the format of the runtime entity tables,
|
|
implying recompilation of all objects, protocols, and categories.
|
|
|
|
Logtalk version 2.15.6 renamed the compiler option "named_anonymous_vars" to
|
|
"underscore_vars" and changed the possible option values form "on/off" to
|
|
"dont_care/singletons".
|
|
|
|
Logtalk 2.16.0 improves support for the declaration and use of operators
|
|
local to objects and categories. Recompilation of any objects and categories
|
|
contain operator declarations is needed in order to take advantage of the
|
|
improvements made.
