Sage Tasks Outline
This is a general outline of targeted areas, including specific tasks, for improving the usability of Sage. The sources include the Sage Usability Improvements List and sagenb/todo.txt, but the scope here is wider. Feel free to make changes.
1. General
2. Build / Test
- Tests:
- Increase coverage.
- Meaningful statistics / benchmarks, e.g., %timeit for individual doctests.
- Build logs:
- Separate file for each spkg for parallel builds.
- Group by install, upgrade, or spkg install event.
- Remotely aggregate and display refreshed statistics.
- Porting:
VirtualBox Sage.
- andLinux Sage.
- Windows.
- Windows build farm.
- Sagelite for Windows.
- Binary distributions that don't use SSE3, etc.
Automated notebook benchmarking and [stress] testing: FunkLoad, Selenium,Watir, Windmill, Zope.testbrowser.
3. Development
Auto-reload / auto-build changed files - attach, paster serve --reload, CherryPy's AutoReload.
More convenient development workflow:
Code review tools - Rietveld.
- Automated, continuous builds and testing for new patches.
4. Documentation
- Document:
5. Notebook: Admin
- Authentication - abstract interface:
- LDAP.
- UNIX accounts.
- Dashboard for server settings / status:
- Statistics: all / logged-in users, load, processes, worksheets [per user], etc.
- Backups: all critical data, selective.
- Configure thresholds, alerts, snapshot behavior.
- Manage user accounts, groups, privileges.
- Restricted version for users.
- Install new / updated modules and spkgs.
- Registration:
- Challenge questions.
- Admin approval.
- Revokable custom tokens.
- Users:
- Groups.
- Privileges.
- Email address as username.
- Use secure tokens to reset passwords.
6. Notebook: Introspection
- Use Sphinx for sagenb.org docstrings.
Matrix B mentioned twice in B.solve_left?: B.solve_left(B, ...).
- Better error detection, e.g., for Maxima command completion.
- Completions link for mobiles.
- Live introspection cells.
- Introspection cross-links.
- Improve introspection / completion interface: floating div, RHS div.
New documentation browser. Send worksheet docstrings to this browser.
7. Notebook: "Modes"
- %timeit.
%cython mode, full and outside sage.
- Slideshow mode.
- interacts:
- Auto updates.
- Live published.
- Control over widget layout.
- Examples to include with Sage.
- Display nicely formatted docstrings (or captions).
- Simplify extension, via HTML templates or an API.
- More widgets: vertical sliders, spreadsheets, interactive plots, etc.
Graph editor - #1321.
- reST:
%rest cells (auto-hide, double-click to show) converted to HTML by Sphinx.
- Preparse in the browser: implicit multiplication, less work for server.
- Rich content, e.g., equations.
- Sage compute bot.
- Add to help page.
- Debugging:
- Prettier tracebacks for %modes.
Python debugger a la Pylons.
Draw - SVG-edit.
- Annotate output from matplotlib's SVG backend.
Code editor a la BeSpin
- Command-line history.
- Syntax highlighting.
- Context-sensitive completion.
8. Notebook: Under the hood
Implement base_url.
Move is_valid_username, etc., out of twist.py.
notebook():
Allow default_mode='python', i.e., not 'sage'.
- Allow a different sage command on a remote machine.
- Smartly manage Jmol applet count, or memory use.
Use Python's logging facility.
- Cythonize pexpect.
- Processes:
- Balance server pool loads.
- Run the worksheet process as another user.
- Make ctrl-c quit the server's reference implementation.
- Upload worksheets without blocking the server.
- Remote worksheet processes.
Use fork, named pipes, and/or memory-mapped files for worksheet processes.
- Client-server and server-server interaction:
- TinyMCE problem.
- Load JS / CSS components on demand.
- Load browser-specific code only in the specific browser.
- Better handling of concurrent worksheet use.
- Server-to-server for backups, possibly with authentication.
- Decouple secure transport from sage/dsage. Use OpenSSL.
- Storage:
- Implement infinite undo with revision logs, not snapshots.
- Track user data / worksheets with Mercurial.
Deprecate the [unused] objects directory.
- Access a user's data directory securely, e.g., via an API.
Use the filesystem or a database, not an sobj:
- Worksheet list.
- Notebook configuration.
Migrate to server / framework: Django, Pylons, Pyjamas, Tornado, etc.:
Switch from twisted.web2 to twisted.web.
9. Notebook: User Interaction
- Help:
- Reorganize help page.
- Search for commands
- linking to similar and related commands
- Easy set up of shipped jsMath fonts.
- Automatic tips for keyboard shortcuts, editing features, etc. Opt out.
- Friendly bug buddy that emails reports, bundles session history, etc.
- Reorganize help page.
- Customization:
- Typeset output default setting.
- Implicit multiplication default setting.
- Custom window close callback.
- Function to update worksheet titlebar.
- Easy backups of own work, with or w/o data, output, snapshots, etc.
Download zip files of multiple worksheets, even if accounts=True.
- Keys
- Restart worksheet shortcut.
- Splash-screen with common keys.
- Insert new cell after current cell shortcut.
Custom shortcuts, e.g., ctrl-bksp to delete previous word, not join cells - js-hotkeys.
- Cells:
- Auto-updating cells, e.g., interacts.
- Prevent text movement by a pixel on cell frame focus.
- Always show links for long output cells, regardless of length or interruption.
- Easily identify idle, queued, and running cells.
Select, delete, (un)group, move multiple cells.
Leading space input bug - #6729.
- 2D / 3D plots:
JavaScript animations.
Mouse-over for coordinates - matplotlib.
Interactively zoom, pan, annotate - canvas, SVG, Flot, Open Flash Chart.
- Worksheets:
- Export screen with checkboxes for images, data, etc.
- Use notebook as IDE for running sage instance.
- Always visible menubar at top of worksheet.
- Make "Browse your computer" upload fields editable.
- Fix "undefined" bug on first save in Safari 4.0.3.
- Don't list "Sage Users" when sharing.

- Toolbar with buttons to interrupt running code, save, attach files, etc.
Parens matching - #3646.
TinyMCE synchronization problem.
