[PATCH] make downloads.dpi use http_user_agent from dillorc
by a1ex＠dismail.de Dec. 10, 2024

Dec. 10, 2024

Hi, Here is a patch which allows wget called from downloads.dpi to use the user agent provided in dillorc, and fallback to the hardcoded Dillo/version agent if not defined.

XSLT
by Schimon Jehudah Nov. 14, 2024

Nov. 14, 2024

Good day, everyone! I would want to know of an example or an elaboration as of how would it be possible to wriite a plugin which would parse XSLT. I want to know how to trigger Dillo to engage such type of a plugin. P.S. Did anyone examine my XMPP plugin for Dillo, yet? Kind regards, Schimon

XMPP PubSub Plugin
by Schimon Jehudah Nov. 9, 2024

Nov. 9, 2024

Good day, to one and all! My name is Schimon, I am a pianist, attorney at law, and I also work on software that mainly involve the technologies of Syndication and XMPP. My current intention, is to design an XMPP client, based on Slixmpp, to allow Dillo to interact with Atom Over XMPP (XEP-0277 and XEP-0472). Atom Over XMPP specifies storage of textual content (be it text or HTML) on XMPP PubSub nodes. It is useful for publishing (see Libervia, Movim, Rivista XJP), annotating resources (see Blasta) and for any sort of mean which may require textual content. References: https://blasta.woodpeckersnest.eu/help/about/xmpp/atomsub https://blasta.woodpeckersnest.eu/help/about/xmpp/pubsub Projects: https://schapps.woodpeckersnest.eu/blasta/ https://schapps.woodpeckersnest.eu/rivista/ I intend to utilize the Python computer language for this task. Any help, encouragement, and especially accompanying (not in the musical sense) my efforts be welcome. This is my first time which I intend to collaborate with Dillo developers, and I am excited by this opportunity. Kind regards, Schimon

Testing without Dillo
by Schimon Jehudah Nov. 8, 2024

Nov. 8, 2024

Greetings! Is it possible to run Dillo plugins without installing them? I ask for two reasons: 1) Ease of development. 2) I fail to activate plugins. ** ERROR **: [Dpi_read_comm_keys] No such file or directory Dpi_blocking_start_dpid: try 1 [dpid]: a_Misc_mksecret: 1j91dh5 dpid started Dpi_get_server_port: can't read server port from dpid.

[PATCH] Hide tab close button
by a1ex＠dismail.de Oct. 28, 2024

Oct. 28, 2024

Hi list, In an attempt to keep the UI as configurable as possible for accessibility and themeing purposes, here is an example patch to hide the close tab button. Since we can already close the tab with the right or middle mouse button click, the button might be useless for some users, and may also be taking up valuable horizontal real-estate in the tab bar. Maybe it seems silly, but when using Dillo on a constrained portrait display, this can be useful. It can probably be made into a dillorc option if there is any interest. --- a/src/uicmd.cc Mon Oct 28 19:01:28 2024 +++ b/src/uicmd.cc Mon Oct 28 19:01:57 2024 @@ -142,7 +142,7 @@ class CustTabs : public Fl_Group { (public) Fl_Group(0,0,ww,th,lbl) { Pack = NULL; focus_counter = 0; - tab_w = 50, tab_h = th, ctab_h = 1, btn_w = 20, ctl_w = 1*btn_w+2; + tab_w = 50, tab_h = th, ctab_h = 1, btn_w = 20; resize(0,0,ww,ctab_h); /* tab buttons go inside a pack within a scroll */ Scroll = new Fl_Scroll(0,0,ww-ctl_w,ctab_h); I've also done some preliminary work to theme the tab bar, scroll bar, url bar, icons, and ui highlights. Dillo isn't really designed for that, so to create a proper user configurable theme-engine will probably be quite a lot of work, and not something that I can handle alone. Regards, Alex

[WIP PATCH] Use SIGUSR1 to reload the page
by a1ex＠dismail.de Oct. 25, 2024

Oct. 25, 2024

Hi Rodrigo, I find your recent idea[0] to refresh the page on local file changes interesting, and it could be a quite useful feature. [0] https://github.com/dillo-browser/dillo/issues/255 I imagine it can be triggered with a tool like entr[1]: ls /tmp/test.html | entr 'pkill -SIGUSR1 dillo' [1] http://eradman.com/entrproject/ So far, I have a working signal handler which will act upon receipt of a SIGUSR1 signal. It just prints the signal # to the console right now. I am trying to make it perform an 'a_UIcmd_reload', but haven't been successful yet: dillo.cc:389:19: error: use of undeclared identifier 'vbw' a_UIcmd_reload(*vbw); ^ 1 error generated bw.h and uicmd.hh are defined in dillo.cc, so its probably a skill issue on my end :) Any hints would be appreciated!

Rendering issue with view source and large embedded images
by a1ex＠dismail.de Oct. 19, 2024

Oct. 19, 2024

Hi, There is a small rendering glitch when trying to view the source of a page which has larger embedded data uri images. See attached screenshot. This is an example of a page which uses large embedded jpegs: https://www.da.vidbuchanan.co.uk/blog/dram-emfi.html When you view the source in Dillo, the issue should be evident. Since the encoded image is just one super-long line in the html, the vsource dpi probably isn't designed to handle that. I don't think its typical that a site will embed large images into the page like this, but maybe its still worth considering. Regards, Alex

Navigation by pages
by a1ex＠dismail.de Oct. 18, 2024

Oct. 18, 2024

Hi Rodrigo, I saw your recent issue on GH: https://github.com/dillo-browser/dillo/issues/268 This is something I have thought about for quite a while. Basically, scrolling sucks, and it would be nice to be able to move up and down the page more cleanly. Obviously we can use PgUP/PgDN keys and spacebar, but I always wanted a way to do this with mouse-only. In the past I had scripted a small window which sits on-top of Dillo in the corner, which had 2 buttons: up and down. This works, but is a bit clunky. So, while I don't have a quick solution to the layout / pagination issues you mentioned, I created a simple toolbar icon which allows page navigation with the mouse. I think it really makes it easier when reading a long page. Patch and screenshot attached. Regards, Alex

scroll_step description
by Kevin Koster Oct. 18, 2024

Oct. 18, 2024

There's a new "scroll_step" option in the example configuration file for 3.1.0-rc1. The comment "Mouse wheel scroll step in pixels" suggests that this only affects the mouse wheel, but it also changes the distance the page moves when the arrow keys are pressed and the overlap of previous page content that's left when you press Page Up/Down. I think that's a little confusing, especially as the value has changed since the default behaviour in 3.0.5 (the old value seems to have been about 25).
