User:Kevin Reid/E tasks

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.

If you wish to help update this list, please do only these:

• Add new tasks to #To classify.
• Move completed tasks to #Completed; I will review them.

As of 06:16, 18 August 2009. When updating this list, consult the main unimp list's diffs since then for what to add/move.

Language features

Algorithmic

• Closest-pair problem
• Long multiplication
• Longest common subsequence
• Non-continuous subsequences
• Point in polygon (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
• Get mouse position
• Window management
• Play recorded sounds (classified here because we can borrow Java facilities in the EoJ case)
• User input/Graphical

Reflective

• Color of a screen pixel
• Simulate key strokes
• Simulate mouse click

Graphics

• Dragon curve
• Plot x, y arrays

Using Basic bitmap storage

• Bitmap/Bézier curves/Cubic
• Image convolution
• Image histogram
• Grayscale image
• Median filter
• Midpoint circle algorithm
• PPM conversion through a pipe
• Quadratic bezier curves
• Read image file through a pipe
• Xiaolin Wu's line algorithm

Mathematics

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

Integers

• Factors of an integer
• Lucas-Lehmer test
• Multiplicative order
• Trial factoring of a Mersenne number
• Seven-dice from Five-dice

Numerics

• Gamma function
• Polynomial regression
• Multiple regression
• Roots of a quadratic function
• Roots of a function
• Sequence of non-squares
• Verify distribution uniformity/Naive
• Verify distribution uniformity/Chi-squared test

Large projects

• Text processing/1
• Text_processing/2
• RCRPG
• RCSNUSP
• Huffman codes
• LZW compression
• Monty Hall simulation
• Pyramid of numbers
• Number names
• Roman numerals
• Sudoku Solver

Rosetta Code processing

• Rosetta Code/Fix code tags
• Rosetta Code/Count examples
• Sort most popular programming languages

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.

Iter/accum/stream tools

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

Matrix type

• Matrix transposition
• Matrix exponentiation operator
• Matrix multiplication
• Reduced row echelon form

Complex type

• Arithmetic/Complex
• Mandelbrot set
• Roots of unity

Rational type

• Arithmetic/Rational

Calendar

• Yuletide Holiday
• Date manipulation
• Date format

Stream IO

• Bitwise IO

Console input

• Select
• Input loop
• Two-dimensional array (runtime)
• User input/Text

Sockets

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

Operating system interfaces

• Secure temporary file
• Fork
• Interrupts
• Query Performance (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
• Create an object at a given address
• Host introspection (currently omitted)

Database

• Table creation
• Table creation/Postal addresses
• SQL-based authentication

Protocol/language implementations

• Active Directory/Connect
• Search for a User in Active Directory
• SOAP
• Send an email
• Window creation/X11

HTTP client

• HTTPS
• HTTPS/Authenticated
• HTTPS/Client-authenticated
• Search Yahoo

XML

• XML/Output
• XML/Input
• XML/XPath

Miscellaneous

• Formatted numeric output
• 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)
• Stack traces (cross-impl agreement)

Needs improvement

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

Special cases

• Measure relative performance of sorting algorithms implementations — waiting on Shell sort, Plot x, y arrays, Write float arrays to a text file, Polynomial regression

Notable omits

• Proof wants a 'proof'
• Rendezvous (Hard to define what this means in E. Intervat perhaps? Is currently marked omit.)
