Release Name: 0.5.9

Notes: This release does not bring many new and cool features (some naturally made it into this release ;-) but it is another step to bringing more advanced functionality like image gallery and blog support to webgen. Since gallery and blog template files will rely heavily on embedded Ruby scripts via erb, haml and thelike, the functionality of the `context` object has been expanded to allow the programmatic inclusion of tags and the rendering of blocks. Another important change in this release is that the naming convention for paths has been made stricter sothat it is easier to derive the (a)(l)cn from a source path. Also note that there have been some incompatible API changes!

Changes: * Major enhancements: - webgen tags can now be accessed and used via the `context` object provided by some content processors ([builder][1], [erb][2], [erubis][3], and [haml][4]). > Tag handlers that do not use the `Webgen::Tag::Base` module now need to provide one more > method - see the [API documentation](../documentation/rdoc/Webgen/Tag/Base.html)! {.information} - Likewise, blocks can now be rendered via the `context` object in the same way as can be done via the [`blocks` content processor][5]. - Change in source path naming convention: only files have different parts now (sort information, basename, extension), directories and fragments not - see [Source Paths Naming Convention][6]! Also note that directories now always have a trailing slash (source paths and canonical names)! > This change may lead to unexpected behaviour if you used the sort information part or an > extension in your directory names! Check this before upgrading to this version! {.warning} - There is the new notion of *passive sources* which do not actively create nodes from paths but only on-demand when a to-be-resolved path is not found. This is, for example, very useful for shipping default files that can easily be overridden with custom files by putting the custom files under the to-be-resolve path in a normal source directory. - There is now a better system for error reporting which allows for more detailed and more specific (with path name and approximate line number) error reports. * Minor enhancements: - Added new content processor [`head`][8] for inserting CSS/JS fragments and links into the head section of an HTML file. Arbitrary `meta` tags can also be inserted. - Added new content processor [`tidy`][10] for running tidy over a (most often generated) HTML file (requested by Michael Franzl). - Special characters like German umlauts and spaces are now allowed in paths (suggested by Michael Franzl). However, note that using paths with such characters may lead to problems when accessing them later on the server! - Added new configuration option [`output.do_deletion`][7] for specifying if generated files should be deleted if their respective source is deleted (suggested by Matthias Kirschner). - Added new configuration option [`tag.coderay.css`][9] which allows the inclusion of external stylesheets. - Added new meta information [`used_nodes`][11] for specifying dependencies for a node (suggested by Hermann Schichl). - The feed source handler now uses the passive sources system for finding its templates and does not rely on the `feedtools` library anymore (which gives a huge speedup). - The sitemap source handler now uses the passive sources system for finding its templates and dos not rely on the `builder` library anymore. And the format of a `*.sitemap` file is now similar to that of a `*.feed` file for consistency. - The `ERB::Util` module is now available when using the `erb` content processor. - Directories are not created anymore if they do not contain any files. - There is now the distinction between textual and binary content processors. - The leading and trailing whitespace of content blocks in Webgen Page Format is not removed anymore. * Bug fixes: - Fixed bug RF#25943: apply command did not work without explicitly specifying a directory - `Tag::Relocatable`: the resolved node is now additionally used as dependency for detecting a change - Switching on `host_os` instead of `arch` for specifying Windows specific behaviour (in preparation for the change of the Windows Ruby Installer). - Using `$?.exitstatus` instead of bit shifting to fix a JRuby issue - webgen tag handlers are now called only if all mandatory parameters are set - Fixed `Website#render` to work when called multiple times - Fixed `Node#is_directory?` to also work when called on a fragment with a trailing slash * Incompatible API changes: - Since one can now get at the parent node of a to-be-created node directly via the Path object, the interface for creating nodes has been simplified. The method `SourceHandler::Base#create_node` now only takes a path parameter and optionally an options hash for special cases (fragment nodes and virtual nodes), `SourceHandler::Base#node_exists` has seen a similar change. The `create_nodes` service signature also changed. Also note that the `before_node_created` message now only sends the path instead of parent and path. > These changes will in most cases render custom source handlers nonfunctional! Read the API > documentation and have a look at the shipped source handlers! {.warning} - `Node.absolute_name` has been removed since it has no purpose anymore! * Deprecation notes: - `Path#cnbase` and `Path#cnbase=` are now deprecated, use `Path#basename` and `Path#basename=` instead! - `Common.absolute_path(path, base)` is deprecated, use `Path.make_absolute(base, path)` instead! Note the different parameter order! - `Node#absolute_cn` and `Node#absolute_lcn` are now deprecated, use `Node#acn` and `Node#alcn` instead!
