I'd prefer you to focus on the dpi part. I mean, this dpi will end asking dillo to do the job.

Hmmm, I think a simple cli switch to tell dillo to listen to the reloads.dpi is enough: dillo -reloads (or something like it) Then, the client communicates with the dpi socket. All this API is what needs to be designed. I'd appreciate you to work on this part. > > > The first duty is to define what is required for a good, > > > general purpose, kind of reloading dpi.

For instance: fprintf(reloads_dpi_socket, "push http://localhost/someurl visible\n"); may be all the client program needs to know. Of course it could also be something like: fprintf(reloads_dpi_socket, "<dpi cmd='reloads' url='http://localhost/someurl' visible>" * The first example makes more clear that it goes trough reloads.dpi who parses it and then sends a dpip tag to dillo to request the job done. This may also be handy: "<dpi cmd='reloads' url='http://localhost/someurl' stop>" Note that it may be good to integrate the remote control functionality into the same dpi (and maybe call it remote.dpi?). This means adding a simple and useful API for help programs to use. For instance to let them push new URLs into the same instance of dillo (and not having to start a new dillo per requested page). Ex: The client app. asks the remote control dpi whether there's a running instance of dillo. YES -> send new to-be-pushed URL NO -> start "dillo -rc" (remote control) send new to-be-pushed URL Please polish along these lines. Cheers Jorge.-

I don't always have time for Dillo. Maybe this weekend, maybe the next. Concerning the reload time, I should be able to fix it when I have time. Concerning the cached images, I will need more time.

tab and frames in webmail

Aug. 27, 2003

hi, Frank de Lange: I apply you dillo tab frame patch,and it seem very cool. But when I go to the www.163.com and www.163.net, I found I can't go into my mailbox.It only says that "This page uses frames, but your browser doesn't support them."And the statusbar shows "Contacting host", for ever. In windows IE I can see the soursecode of that page as following: <html><head> <title>网易邮件系统</title> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> </head> <frameset frameborder=NO rows=80,* border=0 framespacing=0> <frame name="2" src="/newtop.htm" target=contents scrolling=NO marginwidth=0 marginheight=0 frameborder=NO > <frameset border=0 cols=160,* framespacing=0 marginheight=0 marginwidth=0 frameborder=NO> <frame name="folder" src="/cgi/ldapapp?funcid=simplefdr&sid=DBTpkvElTAQAKUwf" target=rtop marginwidth=0 marginheight=0 frameborder=NO scrolling=yes>  <frame name="main" src="/cgi/ldapapp?funcid=foldmain&sid=DBTpkvElTAQAKUwf" target=rbottom marginwidth=0 marginheight=0 scrolling=AUTO frameborder=NO> </frameset> </frameset> <noframes> <body bgcolor="#FFFFFF"><p>This page uses frames, but your browser doesn't support them.</p> </body></noframes> </html> What's wrong? best reguards 　　　　　　　　Jewen_Luo(a)163.com 　　　　　　　　　　2003-08-27

libc dependency in 0.8.0pre (bug 487)
by David McKee Aug. 26, 2003

Aug. 26, 2003

Folks, Updated my CVS at home (Debian 3.0) to 0.8.0pre the other day, and I like what I see. When I tried to do the same at work today (Redhat 6.2), I had problems building. Dpid uses mkdtemp() which was introduced in glibc 2.1.9. However, ./configure has no problems with my glibc 2.1.3. Submitted as bug 487. This constitutes a change from the 0.7 days when (according to the Compatibility web page) any glibc2 would do. Introducing (by hand) a definition of mkdtemp() I found on the web solved all my problems. Browsing the source suggests that you are not in the habit of carrying around lot of little libc bits---and the associated preprocessor code munging---for systems with variant or insufficient libc's. That is fine. It keeps the code base small and simple, but perhaps ./configure should look out for these things. So does this mean some previously working libc's are now going to be excluded, that more conditional compilation stuff will need to go in, or that dpid needs some work to increase it's universal compatibility? -- -- David McKee -- dmckee(a)jlab.org -- (757) 269-7492 (Office)

On-line demonstration against software patents in Europe
by Frank de Lange Aug. 26, 2003

Aug. 26, 2003

Hi'all, As you might know, the European Parliament will vote on software patents in the EU on the 1st of september 2003. I have added a notice to my patch page (http://www.geocities.com/ikbenfrank) about this. Maybe the main Dillo page can do the same? For more info on this issue, go to http://swpat.ffii.org Cheers//Frank -- WWWWW ________________________ ## o o\ / Frank de Lange \ }# \| / +46-734352015 \ \ `--| _/ <Hacker for Hire> \ `---' \ +31-640037120 / \ frank(a)unternet.org / `------------------------' [ "Omnis enim res, quae dando non deficit, dum habetur et non datur, nondum habetur, quomodo habenda est." ]

Frameset & lanlaw.org
by Frank de Lange Aug. 26, 2003

Aug. 26, 2003

I just noticed that my current version of the tab+frame patch still has problems with sites like lamlaw.com, which put body content outside of frameset content. Even though this is against the spec, I've changed my current version of the patch so it displays the right (frameset) content for sites like this. BTW, lamlaw.com is really weird... The sequence of tags is html - head - frameset - /frameset - noframes - /head - body - /body - /noframes - /frameset - /html. So, it has frameset inside head (wrong), /head inside noframes, an extra /frameset, etc. The document claims to be html-4.0-transitional. Sure.

finger plugin
by Andreas Schweitzer Aug. 22, 2003

Aug. 22, 2003

Hi, as promised in a previous mail. Here is the still quite rough finger dpi intended for interested developers : http://www.hs.uni-hamburg.de/~stcd102/dillo/ http://www.hs.uni-hamburg.de/~stcd102/dillo/adpi-0.1.tar.gz It's configure.in is essentially dillo's configure.in :-) you could actually just put finger.c in the ./dpi/ subdirectory of dillo and adjust Makefile.am accordingly. but now I have an actual distribution :-) In the tarball is also what I call so far a library ... well, or at least the routines that have been re-used over and over. Lastly, there is also an experiment : a term plugin, which lets you call arbitrary programs from within dillo (read the source, though !) Installation: just copy the created .dpi files to ~/.dillo/ and edit ~/.dillo/dpidrc (as long as this file exists), then go to dpi:/finger/ If you want dillo to actually recognize the finger URL you will have to edit src/IO/Url.c and sr/capi.c. Search for the string "ftp" inside these two files and duplicate the relevant part for the finger protocol. Or await how dillo evolves :-) Cheers, Andreas -- **************************** NEW ADDRESS ****************************** Hamburger Sternwarte Universitaet Hamburg Gojenbergsweg 112 Tel. ++49 40 42891 4016 D-21029 Hamburg, Germany Fax. ++49 40 42891 4198

[PATCH] version 9 of tab+frame patch, frame support 'complete' (?)
by Frank de Lange Aug. 22, 2003

Aug. 22, 2003

Hi'all, The next version (9) of my tab patch is ready (see bottom of this message for download instructions). Frameset support is now almost complete, manual resize has been added, targeted link functionality has been improved, most frame-related attributes actually work, try it I'd say... Frameset (and iframe) support is enabled by default, it can be disabled using the configure option --enable-xhtml-dtd=strict. You can also use --enable-xhtml-dtd=transitional, which will give you iframe but no frameset support. The default option, --enable-xhtml-dtd=frameset, gives both iframe and frameset support. As usual, tab support can be disabled using --disable-tabs. Other new features (since the last version): - CTRL-U pops up the view source window - CTRL-B bookmarks the current page - CTRL-S pops up save page window New preferences frame_blank_in_tab=([NO]/YES): show frames with "_blank" target in new tab (instead of new window) (read the Browser_Frames.txt and Browser_Tabs.txt documents (in the doc/ directory) and the dillorc file for more info on tab- and frame-related preferences (after applying the patch, of course...)) Of course, the patch also fixes some bugs (and possibly introduces new ones). More on frame/iframe support ============================ Frameset support is based on a new widget (GtkFrameset) which implements <frameset> as specified in xhtml-dtd-frameset. This widget is not Dillo-specific, so it can in theory be used in any GTK program. It is a pure GTK widget, not rooted in Dw. It does not provide any special support for Dw-specific features (eg. the full-screen-off-button is not displayed in the widget). I might make a special version for Dillo after the GTK-version has been debugged sufficiently. What works: - loading (nested) framesets, displaying frames at their appropriate location and appropriate size, including margin width/height and scrolling. - loading (nested) iframes, displaying iframes at their appropriate location and with (mostly) appropriate size and alignment. - manual frame resize (row, column or both at the same time (drag border crossing - this does not work between nested framesets) - all frame-related menu options (in the popup menu). Frame menus can be accessed using the 'This Frame...' button in the popup menu, nested framesets have their own 'This Frameset...' menu. This way, Dillo allows you to limit actions to a subset of a framed document, eg. you can search for text in just one frame/iframe/frameset. Top-level menu options usually refer to the whole document (the frameset). An exception to this is the 'Jump To' option, which refers to the frame in which the menu was opened (question: should this contain the anchors for all frames?). Use the 'Show only this Frame' option in the Frame Options menu to get a full-page view of a frame. Same for 'Show only this Frameset'. What does not work yet: - the full_screen_off_button is not shown in frame documents. Use double-click instead to toggle the full screen setting... - the frameborder attribute works, but dw_gtk_scrolled_frame always draws a (focus) shadow around itself - even with the border size is set to 0. This makes it impossible to draw frames seamlessly.

Some points about the dpi's
by Andreas Schweitzer Aug. 22, 2003

Aug. 22, 2003

Hi, All right, I did it. I made my first dpi ! :-) (heavily based on the hello dpi, though). I will poilsh it a bit and release it soon. It can handle finger URLs. Two caveats : there is no standard for finger URL's, only some drafts http://www.watersprings.org/pub/id/draft-ietf-uri-url-finger-00.txt http://www.watersprings.org/pub/id/draft-ietf-uri-url-finger-01.txt http://www.watersprings.org/pub/id/draft-ietf-uri-url-finger-02.txt http://ftp.ics.uci.edu/pub/ietf/uri/draft-ietf-uri-url-finger-03.txt I implemented version 01 and 03 (if you check the documents you'll know why). However, I did find real finger URL's in the wild. The second caveat : dillo does not automatically call this plugin upon such a URL. It is easy to patch dillo, though. However, this brings me to my questions : 1) will there be a generic URL->dpi mapping ? I could imagine that dpid could actually handle that. I think, one would need to only modify IO/Url.c and capi.c to simply pass through EVERYTHING to the dpi framework. However, some "core URL handling dpi's" that will become part of the dillo package can probably stay hardcoded in dillo. 1b) Either way, I am planing on writing a "catch-all-URL handler" or "fallback handler" or "univeral URL handler" or the like. It will give the user the possibility to start an external program for handling certain URL's. In fact, with my current dpi, this is quite easy to do :-). 2) Does it make sense to write a library for all the dpi's ? I, for myself, did start simply collecting all the functions that I found in dpi/ and are used by many dpi's and put them in a library. Like the various send_stream functions or the get_attr_value function, or the encoding and decoding functions. 3) About configuration (and I think I read comments about this in the code), shouldn't there be only one config file ? and not dpidrc and possibly different configs for all the dpis ? maybe even merge cookiesrc with dillorc ? I guess some of this (or all of it ?) is being worked on by some of you. Maybe this mail helps to avoid duplication :-) Cheers, Andreas P.S.: I also have some ideas about improving the ftp plugin. There is a pretty simple ftp library, and I think it does make sense to actually log in an ftp server and stay logged in for all the operations. (unlike wget which logs in and out for every file). This is not only faster but helps with busy ftp sites, too ! -- **************************** NEW ADDRESS ****************************** Hamburger Sternwarte Universitaet Hamburg Gojenbergsweg 112 Tel. ++49 40 42891 4016 D-21029 Hamburg, Germany Fax. ++49 40 42891 4198
