Looks like dpi > filters/servers are a good start. I think Lua is a good match for Dillo - it's designed to be statically embedded and like Dillo it puts a very high premium on being small and fast. My original motivation was thinking of all the work it take to write eg. a proper fully-featured HTTPS dpi and thinking "it would be *so* much easier to do this in a scripting language instead of C/C++".

Nice! For a few years I've entertained the idea of having lua scripting in dillo. Not only dpi, but also inside. Looks like dpi filters/servers are a good start. -- Cheers Jorge.-

OT: freehg.org gone?

by onepoint＠starurchin.org

Not that it affects us, but did anyone notice that freehg.org has gone? I can't Google anything useful, does anyone know more? Regards, Jeremy Henty

[patch]: fix the obsolete usage of AC_OUTPUT

by onepoint＠starurchin.org

While implementing the Lua DPI I saw that configure.in uses AC_OUTPUT in an obsolete way. This patch changes it to use the modern calling convention. (It also puts each of the generated files on a separate line, which makes it much easier to read patches that modify that list.) Regards, Jeremy Henty

OK, I plan to sit on this for a few more days and then push it if there have been no objections. Regards, Jeremy Henty

Dillo needs scripting

It's a small C program that embeds the Lua interpreter and extends its state with a global function called "dpi". I implemented "dpi" by modifying the main() function of the hello DPI filter in the Dillo source. Once lua-dpi has set up the Lua state it takes its first argument as the name of a Lua script which it loads and runs. > Can we have a look at it? It's a patch to the Dillo source. I'm attaching it. I have made it minimally intrusive: the code is in a new directory called dpi/lua and the only changes to existing files are one-liner changes to dpi/Makefile.am (to make the build recurse into the lua subdirectory) and configure.in (to create dpi/lua/Makefile). NB: I have renamed the dpi to "lua" instead of "starurchin", so the URL is now "dpi:/lua/". Also, if you install Dillo to a prefix other than "/usr" you will have to change the #! line of lua.filter.dpi to match (that's a bug that I will fix if this project gets serious). The current API is much too simple to do anything non-trivial. I think the final version will look more like this: dpi(function (request) url = request.url; html = ...; request:reply(html); end); Regards, Jeremy Henty

Hey nice! What's that lua-dpi? Is it a lua script? Can we have a look at it? Cheers, Johannes
