Palamedes 1.0-a64 TODOs

[ ] Refactor string code. Must remove quotes in parse stage. Remove removequotes junk throughout utils.js and AST.js
[ ] Finish help strings for all functions and operators
[ ] Graph objects, random graphs, display graph, some graph theory functions. Application: random dungeons.
[ ] Re-write SQL stuff, changing MapAST/FilterAST to map/filter functions
[ ] Debugging function to print AST of given input: `ast(table(percent(p)))``

Palamedes 1.0-a61 TODOs

[X] TESTME: Allow scripts to be loaded from the web
[X] New interface for long scripts
[X] Re-write EXAMPLES/REFMAN/README
[X] FIXME: in history/toString identifier identifier should be identifier(identifier); and identifier(identifier identifier) should be identifier(identifier(identifier))

Palamedes 1.0-a60 TODOs

[X] new bin function
[X] run/debug/edit test scripts
[X] code to delete variables/functions/history/tables/conditional probabilities are alliteratively named
forget [num1,...] -- selectively forget history. TESTME
void(v) -- voids a variable. OK
efface(f) -- effaces a function. TESTME
trash(t) -- trashes a table. TESTME
cut() -- clears all conditional probabilities. TESTME
new() -- delete/reset everything. OK
[X] run() -- re-runs everything in history. Seems OK, but outputs all as array, owing to fact it simply calls In[0,Counter()-1]. Perhaps re-write?
[X] Output matrices in either HTML or plaintext. utils.js: matrix_align line 1872
[X] FIXME: This works:TEST <- lookup [choose["foo","bizz"], ["bizz","bazz"] => 0, ["foo", "bar"] => 1] but p(TEST) doesn't, likely owing to to quotes around strings.
[X] FIXME: width/gap table output problem for 0-length objects
[X] A--B operator as a shorthand for [A..B]
[X] Barcharts
[X] Probability distr for lookup
[X] History() in AST.js printing JsonAST wrong: MagicItem ← [object Object] instead of MagicItem ← {"magic":"debug"}
[X] when printing History, skip outer parens when only arg of fcn is primary: block or array or json or scalar (str num, bool)
[X] Make sure History() printing apostrophe in front of SymbolAST
[X] Get rid of quotes around values in r_str in utils.js, e.g.,
```
In[24]  := 'TreasureTypeA1
Out[24] := {"cp":"d6 ≥ 5 ? A1CP : 0","sp":"d6 ≥ 5 ? A1SP : 0","gp":"d6 ≥ 5 ? A1GP : 0","gems":"d6 ≥ 4 ? A1Gems : 0","jewels":"d6 ≥ 4 ? A1Jewelry : 0"}
```
Maybe convert leading and trailing quotes and medial quotes without a backslash prefix to nothing first, then convert \\" to quotes

[X] Implement lookup function, distinct from if:

<s>lookup [z100, [1--9] => Invisibility, [10--15] => Mammal_Control, ...99 => Spell_Storing, 00 => Many_Wishes]</s>

lookup [z100, 01--09 => Invisibility, 10--15 => Mammal_Control, ..., 99 => Spell_Storing, 00 => Many_Wishes]

[X] Make !> and <! operators synonyms for :> and <:
[X] Convert map, reduce, scan, filter and recur into functions, not grammar
- Change map et al so that the default argument is just _. Example: map({_^2}, [1..10])
- Can we make a grammar rule so that 2-arg functions don't need parens? Example: map {_^2}, [1..10] ???
- Change map so that it can take a block like {_^2} or a function like square
- Maybe _ becomes a synonym for id so that {_^2} is just {id^2}. That way myfunc <- 2*(id^2 + 1) can be written more simply as myfunc <- 2*(_^2 + 1)
[X] Add operator to pipe into second argument of 2-argument function ||> and backwards version <||

- `[1..10] > map {_^2}`
[X] Mathematica /@ shortcut for map/infix so we can write the above more simply as
- {_^2} /@ [1..10]
- _^2 /@ [1..10] ???
- square /@ [1..10]
[X] Convert high/low/take/drop into functions, not grammar:
- take(5, [1..10])
- [1..10] ||> take 5
- take 5 <|| [1..10]
- take 5, [1..10] ???
[X] Convert other 2-arg and 3-arg grammar rules into functions: binom, orderstat, pick, geom, pick, comp, nb.
- No plans to convert infix operators (mod, +, sdiff, etc.) or sql (select...from...where) to functions.
[X] Create Help() function. Internally, there will be a help key in each function's JSON. It can be a string or a function.
- Help
- Help Help
- Help function_name
[X] License(): Add new object/function for license, not (just) external license file
[X] Time() function to time how long it takes to run a function
For some reason, jison now produces a function called dice rather than parser. This must be changed to parser in dice_min.js or the web interface won't load the javascript correctly. This didn't happen a year ago with the last release, a57. But I have updated all my nodejs packages, including jison, so something changed. In the build.sh, I use a short sed script to change this:
```
var dice=function(){function
```
to this:
```
var parser=function(){function
```
Fix solve function. NB. solve(ξ^2 + 2 ξ - 1, ξ, 0) |> exact produces -1+√2 ok, but won't find positive root √2 - 1
- need ability to thread over array of starting points
- unreliable solve(ξ^2 + 2 ξ - 1, ξ, [-5:5:0.5]) |> uniq |> exact should produce -1±√2
Parser is a mess
- cleanup
- precedence rules must make sense
- revisit juxtaposition operator
Number converters? Maybe convert the following to numbers (for sorting, arithmetic, etc.) and vice versa
- Unary, Binary, Octal, Hex: Built in recognition of hex and octal. For binary, set base=2 and use juxtaposition.
- Month names and 3-letter abbreviations
- Weekday names and 2- and 3- letter abbreviations
- Hebrew for gematria (Greek too)
Post more blog entries
- The maths problem making Scottish kids cry (mostly written)
- pwgen: randomly generate list of pronounceable passwords. Use Markov chain? (under consideration)
- soundex: find homophones (under consideration)
Form to convert CSV to matrix. CSV-JS looks like it does what I want.
Separate // from |>
- Make // bind tightly
- Continue to let |> bind loosely

Lots to do here! These TODOs may be broken up into several builds.

These TODOs will turn Palamedes into a full-fledged programming language and finally bring the alpha-stage to an end.

After these TODOs, features will be frozen, and the next build will be beta 1.
