Here are some feature suggestions. You might choose a large handful of features to implement as your GSoC project. </p> </div> <h5><a name="geda_integration" id="geda_integration">gEDA integration</a></h5> <div class="level5"> <p> This project involves improving the integration of gwave into the interprocess-communication to and from the other tools, especialy gschem and gnucap. While gwave has an X11-based remote mechanism, Dbus is now the standard, and should probably be used instead. </p> </div> <h5><a name="developing_unit_tests_for_gtk_-20" id="developing_unit_tests_for_gtk_-20">Developing unit tests for GTK+-2.0</a></h5> <div class="level5"> <p> Gwave has been ported to Gtk2. As part of this effort, developing a battery of unit tests for gwave would be useful. The idea is to create a variety of different input files which exercise gwave's ability to import and display waveforms. An important feature for testing will be to compare the displayed waveform against a “golden” waveform to verify rendering correctness. </p> </div> <h5><a name="user_interface" id="user_interface">User Interface</a></h5> <div class="level5"> <ul> <li class="level1"><div class="li"> Replace the existing variable-list with a tree-style variable-selector. allow multiple ways of organizing the tree: file/sweep/variable vs. file/variable/sweep, extract circuit heirarchy from variable names, etc. Perhaps a two-pane tree browser, with the internal nodes of the tree in one pane, and the leaf nodes (variables that can be displayed) in another.</div> </li> <li class="level1"><div class="li"> Add icons to the toolbar elements</div> </li> <li class="level1"><div class="li"> Enhance use of Gtk2.0 file chooser: wildcards for selecting particular types of files,</div> </li> <li class="level1"><div class="li"> Accept drag-and-drop from a file manager to add files, run scripts </div> </li> <li class="level1"><div class="li"> Allow drag-and-drop from one wavepanel to another to move wave</div> </li> <li class="level1"><div class="li"> Remember/restore the position of the windows, both most-recent-session, and also save it in the scripts.</div> </li> <li class="level1"><div class="li"> Add keybinding mechanism</div> </li> <li class="level1"><div class="li"> An undo stack for operations that change the view</div> </li> <li class="level1"><div class="li"> Add a guile console window, where expressions can be typed to query/manipulate/debug gwave objects and variable data.</div> </li> </ul> </div> <h5><a name="data_visualization_and_analysis" id="data_visualization_and_analysis">Data visualization and analysis</a></h5> <div class="level5"> <ul> <li class="level1"><div class="li"> Draw a real graticule in wave panels, including a grid of faint/dotted lines and numeric scales</div> </li> <li class="level1"><div class="li"> Add ability to customize measurements</div> </li> <li class="level1"><div class="li"> Add additional drawing styles: dotted/dashed lines, symbols showing actual datapoints, </div> </li> <li class="level1"><div class="li"> Add user-configurable colors</div> </li> <li class="level1"><div class="li"> waveform calculations (Requires some of the infrastructure work below)</div> <ul> <li class="level2"><div class="li"> display-functions of a single wavevar and scalars</div> </li> <li class="level2"><div class="li"> display-functions of wavevars sharing the same independent var</div> </li> <li class="level2"><div class="li"> more general stuff that computes a new wavevar</div> </li> </ul> </li> <li class="level1"><div class="li"> Additional types of wavepanels for different types of viewing/analsis.
