+ <perex>fifth public release of Relational pipes</perex>
+ <m:release>v0.12</m:release>
+
+ <text xmlns="http://www.w3.org/1999/xhtml">
+ <p>
+ We are pleased to introduce you the new development version of <m:name/>.
+ This release brings AWK support and some smaller changes:
+ </p>
+
+ <ul>
+ <li>
+ <strong>AWK transformations</strong>:
+ now it is possible to write transformations using the classic AWK tool and its language.
+ Relational data can be filtered and modified (incuding additions of new records) or any AWK code can be executed for given relation or records.
+ Structural changes are also possible (adding or removing attributes or dropping relations).
+ The command line syntax is mostly the same as for the Guile transformation.
+ The AWK and Guile transformations are now the most powerful ones in the Relpipe world.
+ </li>
+
+ <li>
+ <strong>AWK and Guile transformations</strong>:
+ option <code>--debug-variable-mapping</code> was added, so it is possible to print mappings (in relational format, of course)
+ between relational attributes and AWK or Guile variables.
+ The mapping is needed because not all valid attribute names are also valid variable names in particular language,
+ thus sometimes some escaping or prefixing is necessary.
+ </li>
+
+ </ul>
+
+ <p>
+ See the <m:a href="examples">examples</m:a> and <m:a href="screenshots">screenshots</m:a> pages for details.
+ </p>
+
+ <p>
+ Please note that this is still a development relasease and thus the API (libraries, CLI arguments, formats) might and will change.
+ Any suggestions, ideas and bug reports are welcome in our <m:a href="contact">mailing list</m:a>.
+ </p>

+ <m:name/> are modular thus you can download and install only parts you need (the libraries are needed always).
+ Tools <code>out-gui.qt</code> and <code>tr-python</code> require additional libraries and are not built by default.
+ </p>
+
+ <p>
+ The module <code>relpipe-in-filesystem</code> uses C++ filesystem API which is supported since GCC 8.
+ This module can be compiled and seems usable even with GCC 6, but requires some patching (switch to the experimental API):

+ The module <code>relpipe-tr-guile</code> uses GNU Guile 2.2 but can also work with 2.0.
+ In such case, it requires this patch:
