really short term todo list

• parsing: 1/2*3/4 (not as expected, but correct)
• parsing: 1/2-3/4 (incorrect)
• install formulaeditor separately on dam02
• check/update really short todo list
• displaying mathml presentation in the page
• xsl transformation using js or web service to product gap/... output
• look into integration with tinyMCE

short term todo list

• manual: document editor1.input_box/editor1.*
• manual: document classnames
• manual: create manual for users (preferably in the webpage, list of symbols, linear input, meaning of symbols)
• manual: create manual for authors (with palette.xml description, options)
• manual: create manual for programmers (describe keywords, and integral/sum)
• manual: first version in english, possibly i18n support
• manual: describe support we offer (what do people have to do before asking us)
• think about generic function application: (f+g)(x) (problem: (x+1)(x+2) )
• add default css option
• reorganize short term todo list
• add support for all mathml symbols, add support for generic mathml described constructs
• vertical align 1/2*3/2
• --x doesn't parse... should this be fixed ? a--2 does parse ? is this desired
• keywords slanted/italic
• check slanted/italic symbols are described
• list symbols available, add more symbols
• look into extending with symbols not yet in sprite fonts (how)
• formulate challenges
• continual error indication (something red)
• multiple objects in one formulaeditor using enter/newlines (as a list ?)
• use classnames for formulaeditor html elements: mathdoxeditor mathdoxtextarea mathdoxinput, ...
• extra symbols: arith1.root: baselining (nicer display)
• speed up: redrawing
• speed up: cursor movement/inserting/deleting
• key repetition (key stays pressed, count as multiple inputs?, does not seem to be a problem under windows)
• speed up: code cleanup : move method to cache symbols/drawImage to a function
• palette: make palette floating with css
• palette: toggle button
• palette: add documentation about the custom palette
• palette customization: depending on user ?
• palette customization: depending on page ?
• extending: preference classes
• extending: documentation
• keywords: further distinction between constants and applications (do not allow pi(a); maybe also disallow 1+sin;) support already present in keyword, not used to check for pi(a)
• implement growing/shrinking matrices, vectors, lists, .... Idea: usepalette for growing/shrinking, as well as shortcuts

mid term todo list

• calculator: make a calculator powered by the formula editor like WIMS has
• show formulaeditor contents when printing
• moving fe around (hans has an url ?)
• option: placing the formulaeditor to the left
• use variable size brackets for abs and list
• getOpenMath/getMathML button
• list of all supported symbols
• slanted letters for variables
• fix vertical navigation with 1/2 inside a matrix
• palette: parse symbols from xml
• some symbols in blue: keywords/parentheses
• reload button
• add != (neq) symbol
• idea: backspace inside a fraction or a sqrt: quick delete
• adding units (like keywords):harder because of prefixes and m/s (which is one symbol)
• selection
• tooltips
• partial copy/paste

items done

• added options: size (and scaling with ctrl +/-), palette.xml origin (must be on the same site as the javascript)
• added sum, product, integral
• silent multiplication 3x becomes 3*x
• automatically require all automatically generate files
• create about popup with version
• created first version of the conversion page: openmath.html
• added support for generic cd.name (from and to openmath)
• added more space around cdot, -, + (no longer needed to make them larger)
• added symbols support for \ and _
• fixed palette on IE (race condition, which should only occur very rarely now, instead of everything palette.xml could be retrieved from cache)
• fixed a bug with navigating out of a vector with the cursor
• going left from a matrix: seems to work now
• OM parser: xml comment support (all are ignored)
• added working integer1.factorial
• custom palette: how to enter blanks : editor1.palette_whitespace
• custom palette:parsing (infix) OMS symbols inside a paletterow: solved with support for keyword types: constant, function, infix
• custom palette: changed margin back to 10.0
• custom palette: now loading from org/mathdox/formulaeditor/palette.xml file (openmath input)
• custom palette: solved blocksymbol different sizes problem: implemented context dependent presentation
• custom palette: describing entries by openmath
• scalability: did enough of cmsy10 and < > pi
• palette: make showing palette optional
• now loading only a small number of files
• automatic versioning from build.xml
• no longer slow with multiple fields, see wortel: books/differentieren/exams/nl/exam1.xml
• fix race condition in main.js (only start loading after main.js)
• document.body.attachEvent race condition fixed (now setting a timeout if document.body does not exist yet)
• ORBEON field update only on blur
• sensible margin for palette/input canvas on mathdoxplayer
• allow toggling palette on/of from mathdoxplayer
• toggling palette on/off (per textarea)
• MS IE: fixed problem with ORBEON forms updating
• sqrt(x,2) when added from palette: problem with filling blue field, problem with clicking with sqrt(x,2)
• extra symbols: list1.list (using curly brackets)
• extra symbols: arith1.root: clicking and the right cursor position
• extra symbols: arith1.root: number above root
• extra symbols: arith1.root: sqrt special case
• extra symbols: arith1.root: convert to semantics
• extra symbols: arith1.root: convert to openmath
• add root(a,b) for bVa) NOTE: not root(a,b) but rt(a,b)
• relations work again (was missing $require in FormulaEditor.js)
• MS Internet Explorer support (first step)
• fixed problems with inserting the wrong item from the palette (this was caused by problems with a PArray inside another PArray and ``reuse'' of colInfo and rowInfo
• fixed problems with redrawing brackets (at least 3 heigh, custom length)
• create a more suitable test website with todo list
• palette: display vectors and matrices with (small) blocks
• scalability
• vector positioning like matrix
• F5 do not reload with error
• fix a index bug with inserting 2 symbols in an emptyrow (done)
• check which other symbols to add(done)
• palette: add symbols from mathadore : 2x2 matrix, 2x3 matrix 2 vector, 3 vector, sin(.) (done
• ignore spaces (done)
• growing brackets (done)
• palette: add palette to page (done)
• palette: add some basic symbols to palette (done)
• reload with F5 (done)
• More space around multiplication-cdot, '-' (done)
• palette: add symbol on 'current' position (done)
