factor/TODO.FACTOR.txt

- i/o tasks hanging around
- compile interruption checks
- check that set-datastack and set-callstack compile correctly in the
  face of optimization
- code walker & exceptions
- floating point intrinsics
- load all sources in stage1
- new basic block optimizer
- fix fixnum/mod overflow on PowerPC
- intrinsic char-slot set-char-slot
- split: return vectors
- set-path: iterative
- investigate if rehashing on startup is really necessary
- remove word transfer hack in bootstrap
- swap @{ }@ and { } syntax
- fix up the min thumb size hack
- long lines of text fail in draw-surface
- off-by-one error in pick-up?
- closing ui does not stop timers
- adding/removing timers automatically for animated gadgets
- [ ... is annoying
  perhaps on the last line of output, if a block doesn't fit, print
  it anyway?
- get outliner working with lots of lines of output
- listener continuations
- test copy-into of a sequence into itself
- vertical alignment of arrows -vs- outliner gadget
- slice: if sequence or seq start is changed, abstraction violation

+ ui:

- multi-part gradients
- tabular output
- debugger should use outlining
- support nested incremental layouts more efficiently
- make-pane should not need world-theme
- only redraw dirty gadgets
- find out why so many small bignums get consed
- use incremental strategy for all pack layouts where possible
- multiline editing in listener
- get stuff in examples dir running in the ui
- text selection
- clipboard support
- get things working without the [ >fixnum ] map hack

+ tutorial:

- multiline code snippets
- s-expression text styling language
- word wrap

+ misc

- signal handler should not lose stack pointers
- sigsegv handling on OS X:

- http keep alive, and range get

+ ffi:

- C structs, enums, unions: use new-style string mode parsing
- alien/c-types.factor is ugly
- smarter out parameter handling
- clarify powerpc passing of value struct parameters
- ffi unicode strings: null char security hole
- utf16 string boxing
- value type structs
- bitfields in C structs
- setting struct members that are not *
- callbacks

+ compiler:

- [ ] [ throw ] ifte ==> should raise 'unbalanced branches' error
- declare slot types for built-ins
- remove dead code after a 'throw'
- flushing optimization
- [ [ dup call ] dup call ] infer hangs
- the invalid recursion form case needs to be fixed, for inlines too
- recursion is iffy; if the stack at the recursive call doesn't match
  up, throw an error

+ sequences:

- specialized arrays
- instances: do not use make-list
- >c/c>: vector stack
- search: slow
- vectorize >n, n>, (get)
- mutable strings simplifying string operarations
- real Unicode support (strings are already 16 bits and can be extended
  to 21 if the need arises, but we need full character classification
  predicates, comparison, case conversion, sorting...)

+ kernel:

- better handling of random arrangements of html words when
  prettyprinting
- friendlier .factor-rc load error handling
- reader syntax for byte arrays, displaced aliens
- out of memory error when printing global namespace
- merge timers with sleeping tasks
- what about tasks and timers between image restarts
- there is a problem with hashcodes of words and bootstrapping
- delegating generic words with a non-standard picker
- code gc

+ i/o:

- faster stream-copy
- reading and writing byte arrays
- stream server can hang because of exception handler limitations
- better i/o scheduler
- utf16, utf8 encoding
- if two tasks write to a unix stream, the buffer can overflow
