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
- 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
- Bitmap/Bézier curves/Cubic
- Bitmap/Bézier curves/Quadratic
- Image convolution
- Bitmap/Histogram
- Grayscale image
- Median filter
- Bitmap/Midpoint circle algorithm
- Bitmap/PPM conversion through a pipe
- Bitmap/Read an image 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
- Factors of a Mersenne number
- Seven-sided dice from five-sided 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
- Execute SNUSP
- Huffman coding
- LZW compression
- Monty Hall problem
- Pascal's triangle/Puzzle
- Number names
- Roman numerals
- Sudoku
Rosetta Code processing
Argue with
Needs a ... to be done well
Reflection toolkit
User-defined exceptions
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
Calendar
Stream 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
- Create an object at a given address
- Host introspection (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 withinterp.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
- Proof wants a 'proof'
- Rendezvous (Hard to define what this means in E. Intervat perhaps? Is currently marked omit.)
Completed
