I was also thinking of extending it to a level in which programs and languages can be run simultaneously: <?program id="g" interpreter="/usr/bin/env guile" ?> <?program id="p" interpreter="/usr/bin/env perl" ?> <?g (define title "My Title") (define user "CoolDude1024") ?> <html> <head><title><?g (write title) ?></title></head> <body> <h1><?g (write title) ?></h1> How are you doing today, <?g (write user) ?>? <?p print "I've written this in Perl!!!" ?>. </body> </html> I was wondering if anybody had any suggestions on this concept before I get too far through coding it. -- - Luiji Maryo (a.k.a.

For what its worth, there is an implentation of something like this inside of gtt, the gnome time tracker. It uses html so that users can write customized reports & layouts, while pulling actual data from the inside of the time-tracker engine. At one point, gnucash was supposed ot do something similar, too, for its reports/graphs, but I am not sure what actually happened there. I really like the general idea, I think it was under-utilized by most of the desktop-application apps. --linas ^ permalink raw reply [flat|nested] 7+ messages in thread

For one thing, the Guile and Perl interpreters would not be able to evaluate just one section of code at a time, because:: - Guile would output "guile> " every line, which would appear in the output. - Perl would require an EOF in order to run the program, which would also end with the state being lost, which is unacceptable. The second problem is that the script would not be able to do cool things like allow editing HTTP headers like in PHP since the programs could not properly communicate with MHP (Multi-lingual Hypertext Preprocessor as it is currently named), thus giving PHP a major advantage. I have come up with a resolution to both of these problems: languages are not referenced by interpreter like [interpreter="/usr/bin/env guile"], it would instead need a plugin-based system so that [language="Guile"] would be translated by a plugin registered by "/usr/lib/mhp/interpreters/Guile.so". How would this solve the problem? Well you see, the interpreter would:: - Be able to evaluate single lines while retaining state. - Be able to communicate with MHP to send messages like "mhp_set_header('content-type', 'text/plain')". This would add a lot more power to MHP, but would also require a plugin for each available language. I currently see no alternative, but anybody may feel free to suggest one. -- Luiji On Wed, Aug 11, 2010 at 10:57 PM, Linas Vepstas <linasvepstas@gmail.com>wrote: > On 11 August 2010 19:12, Luiji Maryo <luiji@users.sourceforge.net> wrote: > > Hello, > > > <?g > > (define title "My Title") > > (define user "CoolDude1024") > > ?> > > <html> > > <head><title><?g (write title) ?></title></head> > > <body> > > <h1><?g (write title) ?></h1> > > How are you doing today, <?g (write user) ?> > > > I was wondering if anybody had any suggestions on this concept before I > get > > too far through coding it. > > For what its worth, there is an implentation of something like > this inside of gtt, the gnome time tracker.

Another idea is to instruct the interpreter not to output this prompt at all, or (even better) to structure the REPL dialogue in a manner most convenient for the controlling (parent) process. ^ permalink raw reply [flat|nested] 7+ messages in thread

I agree with Dan that the large template with small amounts of code is not the way that the web is going now. It really is about dynamically building webpages from the ground up. One strategy would be to use run Guile scripts as CGI scripts, or FastCGI or ModLisp. There are Guile CGI, FastCGI and ModLisp parsing routines in Guile-WWW, if I recall correctly. (http://savannah.nongnu.org/projects/guile-www) For the actual web-page construction, you might consider constructing the webpages as Scheme lists in SXML and then dynamically converting them to HTML and CSS. There is some SXML support in Guile 1.9.x. Consider this paper: http://sjamaan.ath.cx/docs/scheme/sxslt.pdf -Mike ^ permalink raw reply [flat|nested] 7+ messages in thread
