This module provides support functions for writing CGI scripts and
ML Server Page scripts.
[wseq] is the type of efficiently concatenable word sequences.
Building an HTML page (functionally) as a wseq is more efficient
than building it (functionally) as a string, and more convenient
and modular than building it (imperatively) by calling print.
[Empty] represents the empty string "".
[Nl] represents the string "\n" consisting of a single newline character.
[$ s] represents the string s.
[$$ ss] represents the string String.concat(ss).
[&&(ws1, ws2)] represents the concatenation of the strings
represented by ws1 and ws2. The function && should be declared
infix &&
[prmap f xs] is f x1 && ... && f xn evaluated from left to right,
when xs is [x1, ..., xn].
[prsep sep f xs] is f x1 && sep && ... && sep && f xn, evaluated
from left to right, when xs is [x1, ..., xn].
[flatten ws] is the string represented by ws.
[printseq ws] is equivalent to print(flatten ws), but avoids
building any new strings.
[vec2list vec] is a list of the elements of vector vec. Use it to
convert e.g. the results of a database query into a list, for
processing with prmap or prsep.
Shorthands for accessing CGI parameters:
[%? fnm] returns true if there is a string associated with CGI
parameter fnm; otherwise returns false.
[% fnm] returns a string associated with CGI parameter fnm if there
is any; raises ParamMissing(fnm) if no strings are associated with
fnm. Equivalent to
case Mosmlcgi.cgi_field_string fnm of
NONE => raise ParamMissing "fnm"
| SOME v => v
In general, multiple strings may be associated with a CGI parameter;
use Mosmlcgi.cgi_field_strings if you need to access all of them.
[%# fnm] returns the integer i if there is a string associated with
CGI parameter fnm, and that string is parsable as ML integer i.
Raises ParamMissing(fnm) if no string is associated with fnm.
Raises NotInt(fnm, s) if there is a string but it is not parsable
as an ML int.
[%%(fnm, dflt)] returns a string associated with CGI parameter fnm
if there is any; otherwise returns the string dflt.
[%%#(fnm, dflt)] returns the integer i if there is a string
associated with CGI parameter fnm, and that string is parsable as
an ML int; otherwise returns the string dflt.

[mark0 t] generates the HTML tag <t> as a wseq.
[mark0a attr t] generates the attributed HTML tag <t attr> as a wseq.
[mark1 t ws] generates <t>ws</t> as a wseq.
