Logtalk 2.22.0 released

[Paulo Moura]

Hi!

Logtalk 2.22.0 is now available for downloading from the Logtalk web 
site:

        http://www.logtalk.org/

This release introduces a notion of library as a directory of source 
files, adds a dynamic predicate for declaring library names and paths, 
allows source files to be compiled and loaded using the notation 
<library>(<entity>), improves installation instructions and scripts, 
and provides several usability enhancements.


From the release notes:

* Implemented a notion of library as simply a directory containing 
source files. Added a new dynamic predicate, logtalk_library_path/2, 
for specifying library paths. Added sample file for setting library 
paths for the Logtalk standard library and for all the supplied 
examples.

* Added support for using the notation <library>(<entity>) with the 
built-in predicates logtalk_compile/1-2 and logtalk_load/1-2 for 
compiling and loading source files contained on a library, without the 
need to first change the current working directory.

* Changed the library and the examples loading instructions to use the 
notation <library>(<entity>).

* Improved installation instructions and installation scripts. Added a 
new environment variable, LOGTALKUSER, for defining the location of the 
copies of the user-modifiable Logtalk files in a multiple users setup 
environment.

* Added utility predicates to most configuration files for querying and 
changing the current working directory (needed for the 
<library>(<entity>) notation to work).

* Corrected a bug in the code that checks for file existence when 
compiling or loading source files and source metafiles.


The CVS tag for this release is "lgt2220".


Happy logtalking!

Paulo
