language changing

Naderstouhy · 07-21-2011, 04:47 AM

i have changed the funcation set_language() to be able to accept a parameter the language i wish to set, i need to know if there's any way we can modify the .html code in order to be able to access this function and also to change the <html dir="rtl"> tag dynamicly , as i did some research i know that we don't have any python scripts in html, so i need to have a solution for language changing if you have any.

i have thought about some solution:
- making 2 instances of calibre on the server, and switch from one instance to another but i think it wont work because calibre need to be restarted in order to change the language.

any suggestions ?

Briefly:
1) You will have to write code to load translators dynamically.
2) You will have to replace the use of the _() function in the server code with a local function that can be changed dynamically
3) You will need to add a dir variable to all the HTML templates of the server.

whenever you start browser.html, what .py code is being executed first ? and if i add to this .py code :

from calibre.utils.localization import set_translators

set_translators('ar')

will it work properly or i need to make more changes ? thanks

or in fact i need to ask how to add an action for a button ( in the web ) to be able to put the set_dyntranslators('ar') into this action?

my browse.py code is :

connect('browse_language', base_href, self.browse_language)

def browse_language(self, lang):
set_dyntranslators('lang')

i'm getting a 404 (path not found) when compiling

You need to replace every instance of the use of _() in the server code with dynamic_translate() then you need to create an endpoint in browse.py that changes dynamic_translate. Then you need to create some HTML in browse.html that calls that endpoint.

Thanks a lot Mr. kovid, my Code in case anyone wishes to use it is :

in the browse.py code is :

def add_routes(self, connect):
...
connect('browse_language', base_href+'/language', self.browse_language)

def browse_language(self, lang):
set_dyntranslators('lang')

in the localization.py :

def set_dyntranslators(newlang):

lang = newlang
if lang:
buf = iso639 = None
...

in html :

<a href="{prefix}/browse/language" id="nav-ar" title="The Arabic version of this webiste" OnClick='getElementById("htmltag").dir="rtl";getEl ementById("datebet").innerHTML= "التاريخ بين:";</a>

There's no way to do that. Those string are translated at program startup.

Naderstouhy · 07-27-2011, 06:33 AM

for the sorting list i modified : sort_opts.append((x, n)) to sort_opts.append((x, _(n))) then the list worked fine !!!!!

for the category i modified : cats.append((meta['name'], category, icon)) to cats.append((_(meta['name']), category, icon))

That will only work if the language of the main calibre interface is in English or the words are not translated in the language of the calibre interface. Try setting your calibre interface to Spanish and you will see that it wont work.

Sure, open a bug report with your patch attached.

Mr kovid do you have any idea why in Internet Explorer everything worked fine with my code modifications, but while working on Firefox i've got some errors regarding the translations issue, i need to refresh the page whenever navigate in the website in order to have my dynamic translation back ! what is the difference that we are facing here ? and what should i modify in order to have it work on firefox as well ?
