User:Kevin Reid/E tasks
This is Kevin Reid's classification of tasks not implemented in E, or just poorly done in E, by what kind of problem they are, or what kind of library/language work should come first.
As of 16:52, 26 July 2009. When updating this list, consult the diffs since then for what to add/remove.
Should go ahead and do
Problems
Data structures
Algorithmic

Funky control flow
GUI
- Basic Animation
- Keyboard macros

- User Input - graphical
Reflective
Graphics
Using Basic bitmap storage

Mathematics
- Polynomial long division
- improve Median (research better algorithms)

Argue with
Needs a ... to be done well
Reflection toolkit
User-defined exceptions
Parser library
Iter/accum/stream tools
- N distinct objects (needs better answer than accumulator)
Matrix type
Complex type
Rational type
Calendar
Stream IO
Console input
Sockets
- Echo Server
- Sockets
- improve Discover the Hostname (done by shell command, but should be done internally)
Operating system interfaces
FFI
Database
Protocol/language implementations
- Connect to Active Directory
- Creating a SOAP Client
- Send an email
- HTTPS Request
- Client-Authenticated HTTPS Request
- HTTPS request with authentication
- SQL-Based Authentication
- Search Yahoo
- Search for a User in Active Directory
- XML Creation
- XML Reading
- XML and XPath
- Xlib simple window
Miscellaneous
- BNF Grammar
- Formatted Numeric Output
- Print a Stack Trace (cross-impl agreement)
- Write float arrays to a text file (same as Formatted Output)
- Regular expression matching (need agreement on regexp substitution and regexp search-as-opposed-to-match)
- Sort stability (Need to find/write the documentation on this)
- improve Dynamic variable names (Once environment-
withis builtin, show using it together withinterp.setTopScope)
Special cases
- Measure relative performance of sorting algorithms implementations -- waiting on sorts, Query Performance
Notable omits
- Evens Sum To Even wants a 'proof'
- Rendezvous (Hard to define what this means in E. Intervat perhaps? Is currently marked omit.)
