Intelligent Paper
CoSy
is the product
of a unique life optimizing the computer for support in the everyday business of
life . It is unique in providing a notebook/log in which
tapping the F6
key on a line instructs the computer to Eval it . ` Programming is simply writing
sentence in the CoSy
language . CoSy
evolves from Ken Iverson's APL ,
evolved from array algebra , via Arthur Whitney's K
in Chuck Moore's Forth , Each step can be accused of taking simplicity to the extreme .
The essentials of the language are below .
The ` normal person will generally use the highest level vocabulary which builds upon the more fundamental APL vocabulary . The ` nerd may dive all the way down to the machine code underlying the Forth definitions creating the vocabulary .
Captain Picard's Log
Find anything from any fragment you remember
Compute anything in language evolved from mathematics
Find anything from any fragment you remember
Compute anything in language evolved from mathematics
- Ken Iverson's ( father of APL ) Tool of Thought
- Goal like Evernote but Built and Commanded in Open Language
- Effectively a year long course in the APL K and Forth .
- Beyond APL , CoSy
is human level language oriented to everyday business tasks
- Intrinsically a Data Base language | Language for the parallel age |
- Unique interactive environment . Most rapid
development environment . Forth IDE at an undreamed of level
- Each word created is an idea encoded
- Single infinitely flexible environment
- Continually create and refine language at the level needed
The only environment in which you can create new vocabulary word by word
or look at the definition of a word all the way down to the chip
Extreme Simplicity :
Split your note text on lineFeeds and return the lines
containing the
word
And to make it a word
So can write
The rest is Vocabulary
( so a lot of vocabulary is help vocabulary )
- a `
wordis any non blank string of characters .
Space is the prime delimiter .
- The syntax is noun
noun verb aka: RPN ( Reverse Polish Notation ) .
But Note : a verb can look forward in the sentence it is in .
- Tap
F6instead ofEnteron any line & your computer
will try to execute it .
- all nouns are lists . At the Forth level they have a
3 cell header
`( Type Count refCount )`
Indexing is modulo -
- like counting on your thumb & fingers : 0 1 2 3 4 0
: name . . . ;adds a word to the dictionary .
- an extensive vocabulary evolved from APL , mainly
slicing and dicing ,
searching & replacing , and applying verbs to each item in lists .
The philosophical goal of APLs is the succinct expression of algorithms
whether cleaning HTML , handling mailing lists or family accounting ,
or finite element modeling the planet .
- The CoSy notebook environment itself is written in CoSy
R ` text v@ "lf
VM ` cash con cash . And to make it a word
: log R ` text
v@ "lf VM ;
log ` cash con
The rest is Vocabulary
( so a lot of vocabulary is help vocabulary )
( public open code )
