@cindex linterna m@value{AACUTE}gica, what is
@cindex userscript
@cindex how it works

Linterna M@value{AACUTE}gica is ``tiny'' (at least it started that way)
script written in JavaScript for the Greasemonkey extension. It
searches web pages for flash objects with links to video clips and
replaces them with <object> tag that is playable by browser video
plugin. The program is named after an early version of a projection
apparatus.

@node Why it exists?
@section Why it exists?
@cindex why it is needed
@cindex flash disadvantages
@cindex free software flash plugins
@cindex html, video
@cindex HTML5

The short answer: I had spare time and was curious is it going to
work.@*
@ifnottex
@sp 1
@end ifnottex
The long answer: Free software flash plugins like Gnash and
Swfdec do not work well with video flash players on every site. On top
of that:

@itemize
@item
Even with free software plugin you run a lot of proprietary software
as ActionScript
@item
Even the free software plugins use too much resources
@item
Flash is proprietary technology
@item
Flash is not a web standard
@item
Most of the flash objects in a page contain useless stuff
@end itemize

Playback of video clips in a browser is technically possible since the
existence of the <object> tag (around 1999; maybe even before
that?!). To watch a video inside a browser the user always needs a
plugin (HTML5 changes that a bit).  Why it should be flash plugin?

Most of the time I do not have Gnash or Swfdec installed. I do not
care about flash except, sometimes for video clips. I got tired of
using Bash/Perl/Python@dots{} scripts to download video clips and watch
them. Linterna M@value{AACUTE}gica was born.

@cindex pronounce, linterna m@value{AACUTE}gica

The name Linterna M@value{AACUTE}gica is in Spanish. The pronunciation
in @acronym{IPA} is @value{pronouncelm}.  You can also find the answer
to that question by playing the Ogg Vorbis file @file{linterna

@node Building the userscript
@section Building the userscript

Since version 0.0.9 of Linterna M@value{AACUTE}gica the userscript have to be
build, if you have downloaded the source code tarball. If you do not
want to build the script, visit Linterna M@value{AACUTE}gica's web site and
download the compiled version of the script, which is ready for
installation. To build the userscript you will need the following
packages:

@table @samp
@item GNU make 
@item GNU sed 
@item GNU grep
@item GNU bash
@item GNU Coreutils
@command{ls},
@command{cp},
@command{rm},
@command{cat},
@command{tac},
@command{head},
@command{tail},
@command{cut},
@command{tr},
@command{sort},
@command{uniq},
@command{base64},
@command{basename},
@command{mktemp},
@command{test},
@command{echo},
@command{chmod}
@end table

To build the userscript, inside a terminal change the directory to
the source code directory of Linterna M@value{AACUTE}gica and type:
@sp 1 
@samp{make}
@sp 1
If everything went fine, at the end of the building process you should
see the following message:
@sp 1
@example
  linternamagica.user.js is ready.
@end example
@sp 1
To remove all the generated files without the userscript,
type:
@sp 1
@samp{make clean}
@sp 1
To remove all the generated files and the userscript file, type:
@sp 1
@samp{make distclean}
@sp 1

@node Installation
@section Installation

First of all install the userscript extension for your browser and
activate it. For Epiphany it is part of the Epiphany-extensions
package. For GNU IceCat, Abrowser and other versions of Firefox see
the Greasemonkey and/or the Scriptish web pages. For Chromium see the
Tampermonkey website.

@sp 1
@noindent
Probably these extensions are available in your GNU/Linux distribution
as a package.

@sp 1
@noindent
Second, install the video plugin that you prefer.

@sp 1
@noindent
If you have downloaded version of the userscript compressed with gzip
or bzip2, decompress it to get a copy of the file ready for
installation.

@subsection Installation from browser

Load the path where you downloaded Linterna M@value{AACUTE}gica in your browser:
@sp 1		
@samp{file:///home/user/linterna-magica/}
@sp 1
		
You can also start it from a terminal:
@sp 1		
@samp{epiphany file:///home/user/linterna-magica/}

Right-click the user script and from the menu select

@table @asis
@item For Epiphany
``Install userscript''

@item For GNU IceCat and other free software versions of Firefox
``View User Script Source''. In the new window click the Greasemonkey
``Install'' button. If you are using Scriptish, choose ``Install User
Script…''.

@item For Midori
For Midori version 0.3.0 and above select ``Open Link in Bew Tab''. In
the new tab click ``Install user script'' button. Versions before
0.3.0 do not support instala do not support installation of
userscripts from the browser.

@item For Iceape (and other versions of Seamonkey)
``Install User Script…''

@end table

@node Installation from terminal
@subsection Installation from terminal

Another option to install the userscript is to copy it from a
terminal. The paths in the examples bellow might be different in your
configuration and setup.

For Epiphany:
@sp 1		
@noindent @samp{cp linternamagica.user.js \@* ~/.gnome2/epiphany/extensions/data/greasemonkey/linterna_magica.user.js}
@sp 1		

For GNU IceCat:
@sp 1		  
@noindent @samp{mkdir ~/.gnuzilla/icecat/profile/gm_scripts/linterna_magica/}@*
@noindent @samp{cp linternamagica.user.js \@* ~/.gnuzilla/icecat/profile/gm_scripts/linterna_magica/linterna_magica.user.js}
@sp 1

For other free software versions of Firefox:
@sp 1		
@noindent @samp{mkdir ~/.mozilla/firefox/profile/gm_scripts/linterna_magica/}@*
@noindent @samp{cp linternamagica.user.js \@* ~/.mozilla/firefox/profile/gm_scripts/linterna_magica/linterna_magica.user.js}
@sp 1
@sp 1

For Midori:
@sp 1
@noindent @samp{mkdir ~/.local/share/midori/scripts/}@*
@noindent @samp{cp linternamagica.user.js \@* ~/.local/share/midori/scripts/linterna_magica.user.js}
@sp 1

For Iceape (and other versions of Seamonkey):
@sp 1
Iceape works only with Scriptish for which there is no easy way to
install scripts from a terminal. The scripts are located in 
@sp 1
@sp 1
@noindent @samp{~/.mozila/seamonkey/profile/scriptsh_scripts}
@sp 1
@sp 1
but for every installed script there is a definition needed in the file 
@sp 1
@sp 1
@noindent @samp{~/.mozila/seamonkey/profile/scriptsh_scripts/scriptish-config.json}
@sp 1 
which does not seem simple enough to be done by hand.

@node Configuration
@chapter Configuration
@cindex configuration

Linterna M@value{AACUTE}gica has some configuration options. The only
way (for now) to configure it, is to edit the code of the userscript.

To change the configuration of Linterna M@value{AACUTE}gica open the
userscript file and look for @code{var linterna_magica_options}. This
is a JavaScript object that keeps configuration options in
``option'':''value'' format:
@example
 var linterna_magica_options =
 @{
    "debug": 0,
    "log_to": "web",
    "web_log_expand": false,
    "updates": "1w",
    "priority": "self",
    "manual_run": "on",
    "skip_manual_run":
     [
       "youtube.com",
       "vimeo.com",
       "dailymotion.com",
     ],
    "autostart": "off",
    "controls": "self",
    "locale": "auto",
    "cookies": "restore",
    "wait_xhr": "off",
    "quality": "low",
    "format": "mp4"
 @};
@end example

Since version 0.0.10 it is possible to keep your configuration in
separate userscript file. This way your preferences will stay intact
when new version is installed. The userscript with your configuration
must have special structure. If you want this feature, install the
file @file{linternamagica_user_condfig.user.js} from the
@file{utilities} directory. To change the configuration look for
@code{var linterna_magica_user_config}. The format is the same as for
the main userscript file. Have in mind that this file is not going to
be updated and you will have to add manually new options implemented
in future versions, if you don't like the default ones. If an option
is missing in this file, the default one provided by the main
userscript will be used.

@node Disadvantages of the cookies hack
@section Disadvantages of the cookies hack
@cindex cookies, disadvantages

A weird hack to get data from YouTube and Dailymotion without cookies
is used. With cookies the video link data is garbage for Linterna
M@value{AACUTE}gica. Since version 0.0.11, the hack is not needed for
YouTube, and it is not used.

First the cookies are removed by setting their expiration dates in the
past. A request on the background (XMLHttpRequest) for the video page
(for example watch?v=x) is made. The required data is extracted and
the replacement video object is created. Cookies values can be saved
before the request and restored later, but not their original
expiration dates. Restored cookies will expire when the browser is
closed. This hack might break login/favourites/recently watched and
other features for sites supported this way. The browser will
automatically set new values to some of the cookies with the
background request. 

@node Timed-out background requests
@section Timed-out background requests
@cindex timeout, xhr
@cindex delay
@cindex XHR, delay
@cindex background request

For Dailymotion you could use a timeout option. During the first
tests of this fix there were some problems if the background request
was made too soon. It seemed that not all cookies were set by the site
and cleared by Linterna M@value{AACUTE}gica before the request. Later
everything worked without timeout. If you have problems with
Dailymotion increase the value for the ``wait_xhr'' option.

The wait_xhr option is effective for every site that is supported with
background requests.


@node Localisation
@section Localisation
@cindex localisation

In version 0.0.10 translations were split from the main
userscript. Every localisation was a separate userscript with special
structure. In version 0.0.11 userscript files are automatically
generated form PO files. If there is translation for your language and
you want to use it, you will have to build and install it. Compiled
userscripts are also available at Linterna M@value{AACUTE}gica
website.

By default Linterna M@value{AACUTE}gica tries to use the
language of the browser interface if available. You could also set a
custom locale by the ``locale'' config option.

To build all the localisation userscripts in the top source directory
type:
@sp 1
@samp{make locales}
@sp 1


You could also build the scripts from the @file{po} directory:
@sp 1
@samp{cd po}@*
@indent @samp{make}
@sp 1

Compilation of userscript for single language is possible. To do so,
type:
@sp 1
@samp{cd po}@*
@indent @samp{make linternamagica_l10n_@var{langcode}.user.js}
@sp 1

Replace @var{langcode} in the example above with the code of the
desired supported language.

@node Stop execution on every site
@section Stop execution on every site

By default Linterna M@value{AACUTE}gica will run on every site. This is something
that you might not like. You can configure it to run only on some
pages. Open the source file and look for @code{// @@include http://*}.
Remove this and place the same statement for every site you wish to

Linterna M@value{AACUTE}gica is programmed in such a way that it might work (and it
does) with web sites not specifically tested and supported. This is
achieved by regular expressions, patterns and similarities between
video sharing and posting sites. The main idea is that very little
should be needed to support a new site - few changes in a regular
expression, adding an address from where the clip should be extracted
and so on.

There are more than 30 web sites, found with random web searches that
are known to work. See the @file{WEBSITES} file for all known working
sites and more information.
