DEPENDENCY:
This package depends on Meta by Jochen Schmidt, version 1.0.0 or later.
http://www.cliki.net/Meta
Now also: meta fare-utils fare-matcher named-readtables
USAGE:
You can enable Racket-like Scribble behavior for the macro-character #\@ with
(scribble:enable-scribble-at-syntax)
and disable it with
(scribble:disable-scribble-at-syntax)
You may also use
(named-readtables:in-readtable :scribble-racket)
Or
(named-readtables:in-readtable :scribble-both)
Or
(named-readtables:in-readtable :scribble)
For details, see:
http://docs.racket-lang.org/scribble/reader.html
If you additionally pass the keyword argument :skribe t
You will also have Skribe-like syntax.
You can enable only Skribe-like syntax for the macro-character #\[ with
(scribble:enable-scribble-syntax)
and disable it with
(scribble:disable-scribble-syntax)
You may also use
(named-readtables:in-readtable :scribble-skribe)
Or
(named-readtables:in-readtable :scribble-both)
Or
(named-readtables:in-readtable :scribble)
Alternatively, you can enable behaviour for the character #\[
under the dispatching macro-character #\# using
(scribble:enable-sub-scribble-syntax)
(scribble:disable-sub-scribble-syntax)
AT SYNTAX:
The syntax of text after @ is just like
Racket's Scribble syntax by Eli Barzilay.
His Scribble "at-syntax" is described thus:
http://barzilay.org/research.html
http://barzilay.org/misc/scribble-reader.pdf
http://docs.racket-lang.org/scribble/reader.html
BASIC SYNTAX:
The syntax of text within brackets is Skribe-like:
* Text between brackets will expand to a string containing said text,
unless there are escape forms in the text,
which are identified by a comma
followed by either an opening parenthesis or an opening bracket.
* If there are escape forms in the text,
then the text will be split into components,
which will be non-empty strings and escape forms.
The result of parsing the text will be a (LIST ...) of these components.
* A comma followed by a parenthesis denotes an escape form,
whereas a SEXP beginning with said parenthesis
is read and used as a component of the surrounding text.
For instance, [foo ,(bar baz) quux] will (on first approximation) be read as
(LIST "foo " (bar baz) " quux")
Mind the spaces being preserved around the internal form.
EXTENSION TO SCRIBE SYNTAX:
Scribble extends the Scribe syntax in a way that I find very convenient.
* As an extension to Scribe syntax,
if the first character of text within bracket is an unescaped colon #\:
then an expression after it is read that is used
as a "head" for the body of the text resulting from parsing as above.
[:emph this] is read as (EMPH "this")
[:(font :size -1) that] is read as (FONT :SIZE -1 "that")
* As another extension to Scribe syntax,
a comma followed by a bracket will also denote an escape form,
whereas the bracketed-text using Scribble syntax
is read and used as a component of the surrounding text.
This extension is only useful in conjunction with the previous extension.
SYNTACTIC CATCHES:
There are a few possible sources of problems with the Scribe syntax,
and solutions provided by Scribe and Scribble to avoid these problems.
* A closing bracket closes the current text.
Standard Scribe syntax doesn't provide a mean
to include a closing bracket in bracketed text.
* Conversely, so as to prevent difficult to track syntax errors
resulting from typos, Standard Scribe syntax forbids
to include an opening bracket in the text.
* As an extension to Scribe syntax,
you can include any character in the text,
without triggering any special or error-raising behaviour,
by preceding it with a backslash character #\\ in the text
(which preceding backslash character won't be included in the result string).
This is useful to include a character among #\\ #\: #\, #\[ #\] #\(.
* While #\\ will always be able to escape all non-alphanumeric characters,
including the special characters listed above,
future extensions may give a special meaning to #\\ followed by a character
in the regexp range [_a-zA-Z0-9].
If you feel the need for such an extension, I will accept patches;
I suppose that the C or Perl syntax is what is needed here.
* In the bracket-colon syntax extension, after reading the "head",
all spacing characters (space, tab, newline, linefeed, return, page)
are skipped until the next non-space character.
To insert a space character immediately after the head,
just escape it using #\\ as above.
* As a restriction from Scribe syntax, Scribble syntax
doesn't recognize the use of semi-colon as denoting discardable comments.
In Scribe, a semi-colon at the beginning of a line or of bracketed text
or of a string component of bracketed text will denote a comment,
whereas Scribe will ignore any text to the next end of line.
Scribble will include any such text in the result string.
You can emulate the original Scribe behaviour in this regard
by using the preprocessing customization feature described below.
CUSTOMIZATION:
Scribble can be customized in many ways,
to accomodate the specificities of your markup language backend.
* As an extension to Scribe semantics, all strings resulting from reading
bracket-delimited text (as opposed to those resulting from "normal"
double-quote delimited strings that may appear inside escape forms)
may be preprocessed. There may be compile-time or run-time preprocessing.
The variable *SCRIBBLE-PREPROCESS* decides what kind of preprocessing is
done. If it is NIL, then no preprocessing is done (i.e. strings from the
[...] notation will be read as such). If it is T, then run-time
preprocessing is done, via the function PP which itself issues a dynamic
call to the function *SCRIBBLE-PREPROCESSOR* if not NIL (or else behaves
as identity). If it is a function or non-boolean symbol, then said value
is funcall'ed at read-time to preprocess the string form by e.g. wrapping
it into some macro evaluation. Note that when using run-time preprocessing,
you may either lexically shadow the function PP or dynamically rebind the
variable *SCRIBBLE-PREPROCESSOR* to locally select a different preprocessor.
A macro SCRIBBLE:WITH-PREPROCESSOR is defined to do the dynamic rebinding,
as in (scribble:with-preprocessor #'string-upcase [foo]) which (assuming
run-time preprocessing is enabled) will evaluate to "FOO".
* Though the default behaviour of Scribble is to return
a (possibly preprocessed) string if there are no subcomponents,
and a form (cl:list ...) if there are multiple components,
you can customize this behaviour by binding the customization variable
scribble:*scribble-list* to a function that will do the job,
taking as many arguments as there were components (zero for empty text).
If you only want to keep the same general behaviour,
but change the head of the resulting list from cl:list to something else,
then don't modify scribble:*scribble-list*
(or bind it back to scribble:default-scribble-list)
and instead bind scribble:*scribble-default-head* to a symbol
that at evaluation time will be bound to a function
that will properly combine the multiple components.
Note that this scribble:*scribble-list* is processed at read-time,
whereas the function named by scribble:*scribble-default-head* (if applicable)
will be processed at evaluation-time.
* You can select a package from which Scribble will read head forms
of bracket-colon syntax [:head ...] or [:(head args) ...]
by changing the symbol-value of scribble:*scribble-package*.
Typical use is
(setq scribbe:*scribble-package* :keyword)
which will do wonders with AllegroServe's net.html.generator.
Note that this feature happens at read-time, and doesn't affect
the current package used to read escape forms.
If the *scribble-package* feature prevents reading
the arguments to structured head form arguments in the right package,
[:(head form arguments) ...]
then you can fall back to normal scribe syntax
,(head form argument [...])
or qualify the symbols in your head form by their package
[:(cl:head my-package:form foo:arguments) ...]
* You can modify the way that scribble combines
the head and body of bracket-colon syntax
by changing the value of variable scribble:*scribble-cons*
from the default value scribble:default-scribble-cons.
The function takes as parameters the head specified by bracket-colon syntax
and the list of components of the bracketed text, and has to return
Typically, you might want to special case the behaviour
according to the type of the head: cons or symbol.
Note that this happens at read-time.
* Example functions to customize scribble for use with various backends
are given at the end of this file. Check functions
scribble:configure-scribble
scribble:configure-scribble-for-araneida
scribble:configure-scribble-for-htmlgen
scribble:configure-scribble-for-lml2

Please send me updates that include support for your favorite backend.
EXAMPLE USE:
(load "scribble")
(use-package :scribble)
(enable-scribble-syntax)
'[foo ,[:emph bar] ,[:(baz :size 1) quux ,(tata toto [\:titi])] tutu]
==>
(LIST (PP "foo ") (EMPH (PP "bar")) (PP " ")
(BAZ :SIZE 1 (LIST (PP "quux ") (TATA TOTO (PP ":titi")))) (PP " tutu"))
(let ((p "/home/fare/fare/www/liberty/white_black_magic.scr")
(eof '#:eof))
(with-open-file (s p :direction :input :if-does-not-exist :error)
(loop for i = (read s nil eof nil)
until (eq i eof)
collect i)))
(configure-scribble-for-araneida-html)
(html-stream *stdout* '[:html ...])
TODO:
* Make it work with aserve, who, and other backends.
Share and enjoy!

NAMING NOTE
Eli Barzilay started using the name "Scribble" in 2006;
I started using it in 2003 or earlier for my Scribe-like syntax, now Skribe-like.

Syntax extensions akin to Racket’s Scribble and Bigloo’s Skribe
Scribble offers two syntax extensions allowing you to very nicely
mix text markup data and Lisp code. One syntax is a port to CL of Racket’s Scribble syntax,
and the other is a port to CL of Bigloo’s Skribe syntax.
