Revision as of 02:14, 31 January 2011

This is Kevin Reid's personal 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. The presence of items on this list is managed by Task list updater.e (but is not automatically run); the classification is done manually.

Language features

Algorithmic

Closest-pair problem
Long multiplication
Longest common subsequence
Non-continuous subsequences
Ray-casting algorithm
Arena storage pool (Covers both implementing an allocator, and using it to allocate physical memory... Do the first part perhaps.)

GUI

Keyboard macros
Mouse position
Window management
Play recorded sounds (classified here because we can borrow Java facilities in the EoJ case)
User input/Graphical

Reflective

Graphics

Using Basic bitmap storage

Mathematics

Formal power series (similar to Polynomial long division)
improve Median (research better algorithms)

Integers

Numerics

Large projects

Rosetta Code processing

Argue with

Determine if only one instance is running

Needs a ... to be done well

Reflection toolkit

Add a variable to a class instance at runtime

User-defined exceptions

Exceptions/Catch an exception thrown in a nested call

Parser library

Arithmetic evaluation ought to use one even if it's not technically required. (improve)

Iter/accum/stream tools

N distinct objects (improve: needs better answer than accumulator)
...and many other tasks to improve

Matrix type

Complex type

Rational type

Arithmetic/Rational

Calendar

Stream IO

Bitwise IO

Console input

Sockets

Echo server
Sockets
Hostname (improve: done by shell command, but should be done internally)

Operating system interfaces

Secure temporary file
Fork
Handle a signal
Query Performance (improve: done EoJ; needs cross-platform)

FFI

Call a function in a shared library
Call a foreign-language function
Call a function from a foreign language
OpenGL
Host introspection (currently omitted)
Create an object at a given address (currently omitted)

Database

Protocol/language implementations

HTTP client

XML

XML/Output
XML/Input
XML/XPath (improve: needs revisiting when E-XML is better)

Miscellaneous

Formatted numeric output
Write float arrays to a text file (same as Formatted Output)
Regular expressions (need agreement on regexp substitution and regexp search-as-opposed-to-match)
Sort stability (Need to find/write the documentation on this)
Stack traces (cross-impl agreement)

Needs improvement

Dynamic variable names (improve: Once environment-with is builtin, show using it together with interp.setTopScope)

Special cases

Compare sorting algorithms' performance — waiting on Shell sort, Plot x, y arrays, Write float arrays to a text file, Polynomial regression

Notable omits

Rendezvous (Hard to define what this means in E. Intervat perhaps? Is currently marked omit.)

Completed

To classify

Insert new tasks here.

-* Add new tasks to [[#To classify]].
