Code Librarian is a Web frontend to CVS repositories, conceptually a merge of Bonsai and ViewCVS/cvsweb. It allows browsing recent commits to the repositories monitored by date as well as browsing the repository by path as a tree of files and their revisions. Colored unidiffs are shown in popup layers one click away from any browse view, and the interface tries to be both clean and powerful, without scaring away the novice user.
The HTML::Defaultify Perl module is designed to allow CGI programmers to present forms with some fields filled in, which is handy for letting users correct bad input, show records to be edited, and much more. The main function, defaultify(), takes any block of HTML and a hash of field names and values, and returns the HTML with the form fields set to those values. Value lists for multiple same-named fields are supported, as are pages with multiple forms. Several different input formats are supported for compatibility with existing tools.
NovaTK is an object-oriented, cross-platform GUI toolkit. One of the focuses of NovaTK is to facilitate rapid development of cross-platform applications requiring fewer lines of code.
