1. Description




Bigloo 1.9 is a Scheme system devoted to one goal: enabling
Scheme based programming style where C(++) is usually
required. Bigloo attempts to make Scheme practical 
by offering
features usual to traditional programming languages but unusual
to Scheme and functional programming:








The release 1.9a was successfully compiled on:



It should run correctly (but has not been tested) on:





For those who already know Bigloo:

The release 1.9 mostly presents new language constructions. This release
does not improve the compilation results (except that allocation routines
are a bit faster). Here is the list of the changes:

3. Getting Bigloo

You can get Bigloo by clicking on one of these:






If the transfer fails due to connections time out, you can alternatively
pick these files:

They have been produced by the Unix split command.
Unsplited they will produce a uuencoded version of the 
Bigloo1.9a.tar.gz file.



4. Documentation

In order to taste the flavor of Bigloo you can pick here its documentation
Bigloo1.9.ps.gz (120k).



5. Examples



5.1 Foreign Interface

This example illustrates the use of C functions into Bigloo.
This program uses the Unix functions fork, wait and 
sleep to fork and wait for child process. This program illustrate
how to import C functions. This operation require Bigloo extern module
clause that can be automatically produced by the Cigloo tools
(process.scm).


5.2 Foreign Interface (2)

This example illustrates the use of C data structures into
Scheme code. It uses the rusage Unix facility to
measure the time spent by evaluation. This program illustrates
how to define complex C data structures and how to use (allocate
and access) them into Bigloo (runtime.scm).


5.3 Object

This example makes use of the Bigloo object system. It contains the definition
of classes, generic functions and methodes. It instantiate objects and 
illustrates how to use them (object.scm).


5.4 Lexing

This example contains the definition of a regular grammar 
that reads arabic and roman numbers. The main program is a simple 
read-eval-print loop that performs simple numeric computation on arabic 
and roman numbers (roman.scm).


5.5 Parsing

This example illustrates the use of Lalr grammars into Bigloo. This
program contains the definition of regular grammars and one lalr
grammar. It reads a file contains the definition of an
lalr grammar expressed in the Yacc syntax and rewrites it
into the Bigloo syntax (yacc2bigloo.scm).



6. Miscellaneous


6.1 Emacs

My Emacs regular expressions to highlight Bigloo1.9 code:


(setq scheme-font-lock-keywords 
  (list
   (cons (concat "^\(\\(define\\|define-inline\\|define-struct"
		 "\\|define-macro\\|define-generic\\|define-method"
		 "\\|define-command\\)[ ]+\\(\(.*\)\\|[^ \n]+\\)")
	 color-function)
   (cons "^\(module[ ]+[^ \n]+" color-2)
   (cons "::[^ \n)]+" color-7)
   (cons (concat "\(\\(type\\|export\\|import\\|from\\|static\\|use"
		 "\\|include\\|foreign\\|extern\\|Cforeign\\)[ \n]")
	 color-type)
   (cons (concat "\(\\(class\\|wide-class\\|final-class\\|generic"
		 "\\|inline\\|macro\\|infix[ ]macro\\)[ \n]")
	 color-6)
   (cons (concat "\(\\(let[ ]\\|let[*][ ]\\|letrec[ ]"
		 "\\|set[!][ ]\\|with-access\\|instantiate\\|duplicate"
		 "\\|widen[!]\\|lambda[ ]\\|labels[ ]"
		 "\\|multiple-value-bind[ ]\\|match-case[ ]\\)")
	 color-keyword)
   (cons (concat "\\[assert[^\]]*\\]\\|\(assert[^\)]*\)\\|\(error[ \n]"
		 "\\|\(warning[ \n]\\|(pragma[ ]\\|trace \\|\(bind-exit "
		 "\\|\(try \\|\(unwind-protect")
	 color-3)
   (cons "\\(`\\|,\\|'\\|,@\\)" color-2)))
