Re: jumanji - a web browser

@bernarcher: looking forward to seeing JumNav 1.0

would there be a way to use vimprobable2's/vimperator's hints instead?

Currently using this:

var elements = [];
var active_arr = [];
var hints;
var overlays;
var active;
var lastpos = 0;
var last_input = "";
var last_strings = [];

focus_color = "#00ff00";
normal_color = "#ffff99";
opacity = 0.3;
border = "1px dotted #000000";

hint_foreground = "#000000";
hint_background = "#b1ba29";
hint_border = "2px dashed #000000";
hint_opacity = 0.4;
hint_font =  "11px monospace bold";

vertical_offset = 0;
horizontal_offset = -10;

function Hint(element) {
  this.element = element;
  this.rect = element.getBoundingClientRect();

  function create_span(element, h, v) {
    var span = document.createElement("span");
    var leftpos = Math.max((element.rect.left + document.defaultView.scrollX), document.defaultView.scrollX) + h;
    var toppos = Math.max((element.rect.top + document.defaultView.scrollY), document.defaultView.scrollY) + v;
    span.style.position = "absolute";
    span.style.left = leftpos + "px";
    span.style.top = toppos + "px";
    return span;
  }
  function create_hint(element) {
    var hint = create_span(element, horizontal_offset, vertical_offset - element.rect.height/2);
    hint.style.font = hint_font;
    hint.style.color = hint_foreground;
    hint.style.background = hint_background;
    hint.style.opacity = hint_opacity;
    hint.style.border = hint_border;
    hint.style.zIndex = 10001;
    hint.style.visibility = 'visible';
    return hint;
  }
  function create_overlay(element) {
    var overlay = create_span(element, 0, 0);
    overlay.style.width = element.rect.width + "px";
    overlay.style.height = element.rect.height + "px";
    overlay.style.opacity = opacity;
    overlay.style.backgroundColor = normal_color;
    overlay.style.border = border;
    overlay.style.zIndex = 10000;
    overlay.style.visibility = 'visible';

        update_hints(strings[strings.length-1]);
    }
    last_input = input;

}

It's luakit's hinting script, which has been slightly modified. A couple of bugs need to be worked through, but still quite usable.

Re: jumanji - a web browser

Just wanted to say thanks alot for this awesome browser! I've just changed from Firefox/Vimperator to Jumanji! Thanks again!

Btw, untill the annoying bug with JumNav.js v0.4 is fixed(pressing 'f' goes to the top of the page even though you're longer down ,or at the bottom), then portix's hints file(dwb2_hints.js) works great!

Latest version:

wget http://bitbucket.org/portix/stuff/raw/1b8fe0282f20/jumanji/dwb2_hints.js

Re: jumanji - a web browser

thanks portix for your work, i've been using your script since you've posted it here. just two remarks, when i first hit 'f', there's a green selection of the first link, i guess hitting 'enter' should go to that link but it doesn't, you still have to use the assigned letters. second and last remark, your latest revision seems to be way slower than the previous one (on my machine at least)...

edit/ for the speed, i should check a bit more sites but it /feels/ slower on full of links pages.

It is fixable already. You need to change a few lines. See this post.

Again apologies. This bug really is annoying.

Re: jumanji - a web browser

Just pulled in the latest git and now the bookmark access doesn't work. Hit o (for :open),then I type in bbs and then hit Tab (to get access to the bookmarks.

I experience the same since august 22nd. As soon as I hit Tab on an :open command the input line seemingly becomes unresponsive, even to Esc.

Yeah, same here.

Re: jumanji - a web browser

hi,neldoreth, i've seen your project home,http://pwmt.org/projects/jumanji
but i do not know how to compile, can you add a wiki to teach how to compile, or add  a script to automate compile.thanks
if compile by myself, can you write some detail about compile?
# and can i compile jumanji under ubuntu?

Thanks mate!

Btw, sorry for really stupid question, but i'm getting ready for a reinstall of Arch and hence, am polishing up my post-install script which installs apps and sets everything up right unattended, and so the script just wget's your hints file, but as I do not know anything about bitbucket and such, then does the url change upon each new revision(i'm hoping not ) ?

It is fixable already. You need to change a few lines. See this post.

Again apologies. This bug really is annoying.

Thanks mate! Also, I aplogize for posting about issues allready posted as fixable(I haden't read the whole thread before posting, but i'm gonna do that now so as to not make this kinda error again!)

Thanks again!

Re: jumanji - a web browser

you would be better off asking in the ubuntu forums. Their package names might be different. Try to see which packages provide the required dependencies for jumanji.

Last time cc_open was change is "Jun 29" ...
Try to clean a little your history file, if it's too long completion function can take time.

new version add an "history_limit" parameter that limit the history file length.

Re: jumanji - a web browser

Since upgrade to kde4.5, jumanji autostart  runs at boot-up desktop but does not display the selected URL's...no window appears after 30 second download of eight url's.

This action is contrary to the response before kde4.5 wherein the window was opened and jumanji could be utilized for browsing.

Assume that kde4.5 has changed its response to jumanji.

Re: jumanji - a web browser

a new version have been release : 2 new feature :
* ability to add tags to bookmark
* ability to map shortcut and/or buffer to user defined command (use sc_spawn and bcmd_spawn) :
     example :

{"^gfv$",        bcmd_spawn,             { 0,                 "xterm -e sh -c 'cd ~/tempo/flash ; get_flash_videos -p \"%s\"'" } },

+ some bugfix

Re: jumanji - a web browser

I'd like to reiterate a feature request: session support.

I know absolutely no C, but I'd like to poke around tonight with the following approach:

  Just before exit, write out open URLs to .config/jumanji/session
  Right at open, just before processing commandline args, open any urls found in this file

Is anyone else working on a different approach?

good

Important function for you : init_data, main, cb_destroy (take example at cmd_write).

You should add a variable to enable/disable your feature.

(you can contact me by mail if you want help)

I implemented session support for dwb, and could try to adapt it to jumanji.

that'd might be better -- i'm looking at jumanji.c right now and it's over my head to say the least.

i have the same problem.

i tried everything but its still the same. deleted the bookmark/history/cookies files, completely removed jumanji and reinstalled it, set a history_limit but nothing helps.

Re: jumanji - a web browser

I made some error (cherry pick a former commit git without checking what it as done ...) I last version ... so I fix a bug and remade it in the following patch.

I just send 2 new patch to neldoreth to correct 2 completion bug :

• default search engine : truc
  another search engine : much
  :open muchmuch

  -> it should search with "truc"
  -> currently it take "much"

• if you search for "machin chose", currently it only record "machin" in the history

i tried everything but its still the same. deleted the bookmark/history/cookies files, completely removed jumanji and reinstalled it, set a history_limit but nothing helps.

Can you open a bug report and give configuration, history, bookmark file (just a sample that allow me to reproduce the bug)

I was not successfull in adapting the dwb-session support without heavy changes, so only the currently loaded url in
each tab willl be saved, not the history of each tab. I also noticed, that there is a bug when loading more than one
url at startup which also affects the patch: jumanji will not have keyboard focus before clicking somewhere on the
webpage.
