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 to 100%.
    • Fix all sagenb doctests and run them from Sage library.
    • 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:
    • andLinux Sage.
    • Windows.
    • Windows build farm.
    • Sagelite for Windows.
    • Binary distributions that don't use SSE3, etc.
  • Notebook load tests - The Grinder, FunkLoad, Pylot, Watir, Zope.testbrowser.

3. Development

4. Documentation

5. Notebook: Admin

  • Don't list all users' worksheets.

  • Authentication - abstract interface:
    • LDAP.
    • UNIX accounts.
  • Dashboard:
    • Real-time and cumulative statistics, aggregate and per user.
    • Backups: complete or selective.
    • Manage user accounts, passwords, groups, privileges.
    • Send email to all registered users.
    • Install new / updated modules and spkgs.
  • Lots of options with sensible defaults:

    • Email address as username.
    • Secure tokens to reset passwords.
    • Moderated new account registration.
    • Custom analytics tags, geolocation (ClustrMaps).

6. Notebook: Introspection

  • 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. Open worksheet docstrings to this browser.

7. Notebook: "Modes"

8. Notebook: Under the hood

  • Implement base_url.

  • Deprecation message at top of old notebook .py files.

  • Move is_valid_username, etc., out of twist.py. A validation module for all types of notebook form fields.

  • notebook():

    • Allow default systems besides 'sage'.
    • Allow a different sage command on a remote machine.
  • Manage Jmol applet count / memory use - sage-notebook.

  • Use Python's logging facility.

  • Component architecture.

  • Cythonize pexpect.
  • Processes:
    • Balance server pool loads.
    • Run the worksheet process as another user.
    • Reference implementation:
      • Make ctrl-c quit.
      • Don't put "data" link in all output cells.
    • Don't blocking the server: making docbrowsers, etc.
    • Remote worksheet processes.
    • Use fork (cf. #6967), named pipes, and/or memory-mapped files for worksheet processes.

  • Client-server and server-server interaction:
    • Load JS / CSS components on demand - Ajile.

    • Server-to-server backups, possibly with authentication.
  • Decouple secure transport from sage/dsage. Use OpenSSL.
  • Remote access Python API - Google Documents List Data API.

    • (Non-)authenticated modes.
    • Manipulate, share, up/download, publish worksheets at a given Sage(Forge) server.
  • Storage:
    • Fix worksheet.autosave().

    • Always retrieve worksheet content from disk on open.
    • Use a revision control tool (e.g., Mercurial) for undo, history, snapshots, etc.
    • File size limit - auto-delete and warn above threshold.
    • Access a user's data directory securely via the new storage API.

    • Handle permissions better for directories, history, output, conf files, etc.
  • Migrate to server / framework: Django, Pylons, Pyjamas, Tornado, etc.:

9. Notebook: User Interaction

    • 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.

    • Defaults: typeset, implicit multiplication, 3D viewer, rename "Untitled" worksheets.
    • Custom window close callback.
    • Function to update worksheet titlebar.
    • Easy backups, selective or complete.
    • 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:
  • Worksheets:
    • Export screen with checkboxes for images, data, etc.
    • Use notebook as IDE for running sage instance.
