qtruby overrides "to_s" depending on user's LOCALES

[Iñaki Baz Castillo]

Hi, is it an appropiate list for asking about QtRuby?

Note the following issue:

=2D---------------------
~# export LANG=3Des_ES.UTF-8

~# irb1.8

irb> require "Qt4"=20

irb> num =3D 1.1
irb> puts num
1.1

irb> app =3D Qt::Application.new(ARGV)
#<Qt::Application:0x7f48392e6a70 objectName=3D"irb1.8">

irb> puts num
1,1
=2D---------------------

As you can see, after creating a Qt::Application instance, FixNum#to_s has=
=20
been overriden and prints the number in a format depending on user's LOCALE=
S=20
(in Spanish 1.1 is displayed as 1,1).


I've critical issues with it because I use some external libraries as=20
httpclient which creates wrong HTTP request after creating a instace of=20
Qt::Application:

GET /index.html HTTP/1,1 <--- Note 1,1 !!!


Is there any way to disable this behaviour in QtRuby? any workaround?
Thanks a lot.

You can certainly post QtRuby related questions here, but probably you'll g=
et=20
more answers using the qtruby mailing list (e-mail address removed) or the qtru=
by=20
forum: http://rubyforge.org/forum/forum.php?forum_id=3D723.

Regarding your question, you can find an explaination of why this happens (=
and=20
some workarounds) in this thread of the qtruby forum:=20
http://rubyforge.org/forum/message.php?msg_id=3D67059

If you only want a quick solution, you can do the following: create a=20
Qt::Locale object based on the C locale using Qt::Locale.c, sets its=20
number_options property to Qt::Locale::OmitGroupSeparator and use its=20
to_string method to create the string. Something like this:

x =3D 1234.567
l =3D Qt::Locale.c
l.number_options =3D Qt::Locale::OmitGroupSeparator
puts l.to_string(x)

Without changing the number_options property, you'll get a number separator=
in=20
the string (in the example, you'd get the string "1,234.567").

I hope this helps

Yes, after sending the mail I found the same thread

If you only want a quick solution, you can do the following: create a
Qt::Locale object based on the C locale using Qt::Locale.c, sets its
number_options property to Qt::Locale::OmitGroupSeparator and use its
to_string method to create the string. Something like this:

x =3D 1234.567
l =3D Qt::Locale.c
l.number_options =3D Qt::Locale::OmitGroupSeparator
puts l.to_string(x)

But this is not valid to me since I use 3rd party libraries (as httpclient =
=20
which suffers this issue when generating a HTTP request).

Then, I assume that I must change the locales globally but this would break=
=20
the Qt translations and so...

Dark issue...

Thanks a lot.

You can try redefining the Float#to_s method after creating the application=
,=20
using the code I suggested inside it. This works in a simple example, but I=
'm=20
not sure what would happen in a real situation.

require 'Qt4'

a =3D Qt::Application.new []

class Float
def to_s
l =3D Qt::Locale.c
l.number_options =3D Qt::Locale::OmitGroupSeparator
l.to_string(self)
end
end
x =3D 1234.567
puts x

Thanks, I already saw this solution in the RubyForge thread. However I'm=20
afraid of what could happen if this issue affects to more Ruby classes than=
=20
just Float. But it seems the bets solution (even if it's obviously a painfu=
l=20
hack XD).

Thanks a lot.
