The Eclipse Notebook
The Eclipse Notebook is an Eclipse editor to manage your notes. All notes are stored in a single XML file in your workspace, making it easily manageable with version control etc. For authoring, it supports embedded Graphviz/Dot (needs to be installed separately) and Wikitext. The Eclipse Notebook allows you to view, filter and edit your notes in two ways (each in a different tab of the editor): As an HTML preview (which can be saved) and as a form editor. In both modes, the notes can be filtered for flexible search criteria (like all notes tagged as x or all notes from 2003, etc). The filtered notes can be exported as an HTML page or as a new Notebook file.
Installation: The Eclipse Notebook can be installed from the update site at http://quui.de/updates (requires Eclipse 3.4, aka Ganymede). Use the wizard to create a new empty Notebook after installation. Note that this is an early release, and out of the box will only work on Linux systems. On other platforms, you currently need to add “-Dfile.encoding=UTF-8” to your eclipse.ini file. It also has some other rough edges, e.g. no Undo in the Edit tab, so you have been warned.
