\ cora_4.0.fs -- Coraphyco COnversion RAtios and PHYsical COnstants
\ Version 4.0
\ 2011/6/14 David Meyer <papa@freeshell.org>
\ Coraphyco provides a Forth environment to facilitate conversion of
\ quantities among a large variety of measurement units and systems.
\ Inspired by Frink by Allan Eliasen.
\ Changes in version 4.0
\ - Convert to integer arithmetic from floating-point for
\ portability and usability.
\ - Rewrite user interface to present unique word for each
\ conversion instead of unit-to-base constants and generic
\ conversion word ->.
\ Notes:
\ - On Zaurus, one cell is four bytes, therefore max. single-
\ precision integer is $ffffffff = 4294967295 (unsigned) or
\ $7fffffff = 2147483647 (signed)
\ - NetBSD (SDF) compilation uses eight-byte cells. Max. single-
\ precision integer: $ffffffffffffffff = 18446744073709551615
\ (unsigned), $7fffffffffffffff = 9223372036854775807 (signed)
\ - Largest conversion ratio: parsec:mm (30856775813057300000.)
\ (requires double-precision for integer arith., even on SDF)

Forth Strings
In order to flexibly generate HTML, Forth requires the ability to
construct strings of arbitrary length in memory by concatenating and
nesting multiple string segments.
There are several string-handling Forth modules available, but none
are straightforward, so I'm considering a custom module.
For string concatenation, my first idea was to allocated space
for the combined string for each concatenation, but I'm afraid
generation of a page of HTML in memory would require allocating
several times the final page size as each string segment is combined
and recombined several times into larger and larger sections or the
document.
An alternative idea is to allocate two buffers each of the estimated
maximum page size. Then all concatenations are expressed as appending
and/or prepending strings to the current pafe image. An appended
string could simply be copied to the end of the page buffer. To
prepend a string, the copy buffer would be initialized with the
string, page buffer contents appended, then the resulting combined
string copied back to the page buffer. Would have to track end of
page image within buffer. This would limit memory usage to twice the
estimated maximum page size, but would require a check for buffer
overflow on exceptionally large pages.
Current average size of *.html, *.txt, *.org files in cavenet
green dataset is approx. 2500 bytes. Average word count per file is
24000.
Another alternative: use an array of string addesses and one of
string lengths. Concatenate strings by appending or inserting
compiled string addresses and lengths in their respective arrays.
This would avoid duplication of strings and memory for them. Would
impose maximum on number of string segments that could comprise
a web page.
Taking as an upper estimate each word in a page requiring a start
and an end tag would make an average of approximately 72000 string
segments.
Of course, must ask if complexity of building strings in memory
before printing is justified versus just printing strings in
sequence as they occur in processing.

Forth Application Presentation -*-org-*-
Date: 2011/11/30
How should an application implemented in Forth be presented to users?
I can think of the following formats.
1. Forth Extension: User invokes application with word(s) in the Forth
interpreter.
* Advantages: Most flexible and portable, immediate debugging.
* Disadvantages: Requires user to have access to shell and Forth
interpreter. User must know how to use Forth
interpreter. Text-only interface.
2. Shell Application: User invokes shell script that starts Forth
interpreter and invokes application.
* Advantages: Low impact on implementation, good portability. User
need not know Forth or Forth interpreter.
* Disadvantages: User must have shell access. Text-only
interface. Debugging requires modulization of
application. Dependency on Forth interpreter interface for
argument handling, environment var's, etc.
3. CGI Application: User invokes application from browser via CGI
script.
* Advantages: User can access application from any platform with
web browser. User needs no knowledge of Forth or
shell. Interface can use text styling and graphics.
* Disadvantages: Requires web server running on application
host. Dependency on Forth interpreter interface for environment
var's, etc. Application must wrap output in HTML. Must finesse
dictionary, stack persistence.
4. GUI Application: Aplication packaged as GUI program invoked on
user's PC.
* Advantages: Easiest access for user. Greatest options for
interface media.
* Disadvantages: Highly dependent on user's platform. Depends on
linking graphics libraries with Forth modules. Requires user to
install application on own PC.
Currently, I don't possess the knowledge to implement pattern 4., and
it has so many disadvantages I doubt it would be worthwhile even if I
could.
Pattern 2. does not offer much meaningful advantage over
pattern 1. (Users who can use the shell are able to learn enough
Forth to invoke the application.)
Therefore, I expect to do initial development as a
pattern 1. application, then make a pattern 3. wrapper for
appropriate aplications.

Forth Revisited
I was taking a look at the Coraphyco unit converter program I did in Forth almost five years ago (can't believe it). I'd forgotten how to use the cute little thing, so I'm now determined to learn enough Forth to put in the help commands I've been intending to add all along.
In the process, I started falling in love with this little language again. Maybe Common Lisp can wait? At least I want to include Forth as a tool in my online "world building".

\ html5cgi.fs -- Generate HTML5 tags for CGI script
\ 2016 David Meyer <papa@sdf.org> +JMJ
\ Tags are generate with words with format *X*, where X usually corresponds to the
\ tag to be generated, and which generally have a stack effect like:
\
\ ( c-prefix c-content [c-attrib ...] -- c-result )
\
\ Where: c-prefix is a pointer to a counted string containing the preceding contents
\ of the current element; 0 when the current tag will be the first
\ contents of the element.
\ c-content is a pointer to the contents for the current tag.
\ c-attrib points to one or more optional strings for tag attributes.
\ c-result points to a string concatenating the prefix contents with the current
\ tag (input strings are recycled to the heap).
\ Supported tags/structure:
\ *http-resp*
\ *html*
\ *head*
\ *title*, *style*, *meta*, *base*
\ *body*
\ *article*, *aside*, *div*, *header*, *footer*, *nav*, *section*

\ lcstr.fs -- Long counted string data type
\ 2016 David Meyer <papa@sdf.org> +JMJ
\ Long counted strings (lcstr) are similar to standard counted strings, except
\ that the string length is stored as an unsigned single-precision integer (4
\ bytes) instead of a character (which limits standard counted strings to 255
\ character maximum length). Long counted sting maximum length is
\ 256^4-1 bytes subject to the limit of heap space allocation.
\ Stack effects, variables, etc. representing long counted strings will
\ conventionally start with "L", addresses of long counted strings with "L-".

\ MAILFIG program to handle forms for comments to FIG
\ This is an ANS Forth program requiring:
\ 1. The File Access word set.
\ 2. The words CMOVE and COMPARE from the String word set.
\ 3. A system dependent word GETENV to get the specified
\ environment string,
\ GETENV ( str count -- str' count' )
\ 4. The word STDIN to get the file ID of standard input.
\ 5. The words OPEN-PIPE and CLOSE-PIPE to open and close pipes to
\ processes. (These are communicated with via the normal File access
\ words).
\ 6. READ to write to Unix file descriptors (because of a problem with
\ ThisForth 94-09-12).

Forth Sandbox -*-org-*-
Date: 2011-11-04
A project I think I'll put on a front burner soon is my web-based
Forth programming environment. I've had a prototype[1] online for
several months, and it's already been handy.
Since the purpose is to execute arbitrary code from arbitrary
programmers, security is big concern and should be developed in
parallel with primary functionality. (The interface is currently
secured with HTTP basic authentication, but that will not be
sufficient when made publicly available.)
I have so far identified three technologies I may use to provide
security (probably in combination).
1. wordlists can block access to problematic words within the Forth
environment.
2. Plash is a user program that creates a restricted sandbox
environment and executes a specified program in the sandbos
3. Host the program in an isolated virtual server (VPS).

Yuko Development Notes
* Purpose
To replace Cora Phyco with unit conversion system using primarily
integer arithmetic.
* Style
Instead of Cora Phyco-style
conversion-constants-with-universal-converter, use more conventional
function-per-unit-pair style. Results not prnted but left on top of
stack for user to print or use in further calculation.
Reduce supported units to minimum necessary to reduce number of
functions to program.
Reduce all ratios to lowest terms to reduce chance of overflow.
* Conversion Ratios
The statement "The ratio of unit A to unit B is x:y" means that for a
given quantity, the magnitude of the quantity measured in unit A and
the magnitude of the same quantity measured in unit B are in the
ratio x:y. (NOT the ratio of the quantities of 1 unit of A and 1 unit
of B.)
