Hi
I want to make a web browser in Ruby Tk. I used "net/http" to connect
to net. url is to be given in Tk entry. I am getting data from url
using "response = http.get(url)" . when i printed "response.body" it
gives the HTML source of the given Url. Now I want to display the
content in Ruby Frame. How can i print this ( data of url) in Ruby
Frame.
Please Help

When I run Ruby's source archive ("ext/tk/sample/tkextlib/tkHTML/hv.rb").
I got error
/usr/local/lib/ruby/1.8/tk/package.rb:86:in `require': TkPackage can't
find package Tkhtml (RuntimeError)
from /usr/local/lib/ruby/1.8/tkextlib/tkHTML/htmlwidget.rb:15
from /usr/local/lib/ruby/1.8/tkextlib/tkHTML.rb:13:in `require'
from /usr/local/lib/ruby/1.8/tkextlib/tkHTML.rb:13
from hv.rb:10:in `require'
from hv.rb:10
When i run the program in example given by you it also gives same error.
I want to display HTML text in Ruby widget as the HTML file displays
in web browser.
bye

Hi,
I am new to ruby. How to install the extension onTcl/Tk
environment and use the Tcl/Tk's library on Ruby/Tk ? My OS is fc3
and I installed everything of the option on fc3 cd. My ruby version is
"ruby 1.8.2 (2004-12-25) [i686-linux]". I tried to install from
http://www.hwaci.com/sw/tkhtml/... link but it doesn't work.
ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.2-previ... is
also not working.
What packages do i need for installing the extension? I don't know
about Tcl . How to check it is properly installed? It would be
helpfull if you send me some suitable link for these.
Thanks

Hi
I installed ActiveTcl8.5.0.0b3.121397-linux-ix86.tar.gz in
/usr/local/ActiveTcl.
Now how to " add ActiveTcl's library directory to your library path"
I tried to use

[bash]$ D_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH \
ruby your-Ruby/Tk-script
it gives "ruby: No such file or directory -- your-Ruby/Tk-script (LoadError)"
how can i find the path of "ruby your-Ruby/Tk-script"? Is it
"/home/sujeet/Soft/ruby-1.8.2/ext/tk" or it is in /usr directory or
else.

[bash]$ _LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH irb
gives "irb(main):001:0> "
what to do next?

or how to use TCLLIBPATH ?
'Tk::AUTO_PATH.value' or 'Tk::AUTO_PATH.list' gives
bash: Tk::AUTO_PATH.value: command not found
bash: Tk::AUTO_PATH.list: command not found

After this in ./configure --with-tcl-dir=/usr/local/ActiveTcl/ > --with-tk-dir=/usr/local/ActiveTcl/ > --with-tcllib=tclstub8.4 > --with-tklib=tkstub8.4 > --enable-tcltk-stubs )
step what is tclstub8.4 ? should i replace it with tclstub8.5 as my
package is ActiveTcl8.5.0.0b3.121397-linux-ix86.tar.gz.

Rest steps are clear. This will be a great help for me .
Thanks

Hi,
This is summary of what i did.
I got ActiveTcl8.5.121397-linux-ix86.tar.gz.
1)I used :
tar xvzf ActiveTcl8.5.0.0b3.121397-linux-ix86.tar.gz
2)cd ActiveTcl8.5.0.0b3.121397-linux-ix86.tar.gz
3)sh ./install.sh
Now, ActiveTcl is installed at /usr/local/ActiveTcl
4)add ActiveTcl's library directory to your library path
i used :
export PATH="/usr/local/ActiveTcl/bin:$PATH"
3) i installed ruby
tar xvzf ruby-1.8.2.tar.gz
4)cd ruby-1.8.2
5)./configure --with-tcl-dir=/usr/local/ActiveTcl/ --with-tk-dir=/usr/local/ActiveTcl/ --with-tcllib=tclstub8.5 --with-tklib=tkstub8.5 --enable-tcltk-stubs
6)make
7)make install
8) LD_LIBRARY_PATH=/usr/local/ActiveTcl8.5.0.0b3/lib:$LD_LIBRARY_PATH
/usr/local/bin/irb
irb(main):001:0> require 'tk'
=> true
irb(main):002:0> Tk::TK_PATCHLEVEL

irb(main):003:0> Tk::AUTO_PATH.list
=> ["/usr/share/tcl8.4", "/usr/share", "/usr/local/lib", "/usr/lib",
"/usr/share/tk8.4"]
irb(main):004:0> require 'tkextlib/tkHTML'

from (irb):4
9)since i installed ActiveTcl8.5.0.0b3.121397-linux-ix86
but Tk::TK_PATCHLEVEL, gives "8.4.7"
Is this mean I have ActiveTcl"8.4.7" installed?

Also,Tk::AUTO_PATH.list
doesnot give "/usr/local/ActiveTcl/"

What sould I do?
How to uninstall ActiveTcl"8.4.7"
How to add Path of "/usr/local/ActiveTcl/" in k::AUTO_PATH.list

Thanks

hi, Firstly i add
/usr/local/ActiveTcl/lib to /etc/ld.so.conf on top
But it didn't work. Then I
i uninstall Tcl package of fc3.
i used " rpm -qa | grep tcl"
rpm -e --nodeps tcl-devel-8.4.7-2
rpm -e --nodeps tk-8.4.7-2
rpm -e --nodeps tcl-8.4.7-2

After this I reinstall ActiveTcl is installed at /usr/local/ActiveTcl
and set path.

Then i used tar xvzf ruby-1.8.2.tar.gz
cd ruby-1.8.2
/configure --with-tcl-dir=/usr/local/ActiveTcl/ --with-tk-dir=/usr/local/ActiveTcl/ --with-tcllib=tclstub8.5 --with-tklib=tkstub8.5 --enable-tcltk-stubs

make
make install
Then , LD_LIBRARY_PATH=/usr/local/ActiveTcl8.5.0.0b3/lib:$LD_LIBRARY_PATH
=/usr/local/bin/irb
irb(main):001:0> require 'tk'
LoadError: libtk8.4.so: cannot open shared object file: No such file
or directory - /usr/local/lib/ruby/1.8/i686-linux/tcltklib.so
from /usr/local/lib/ruby/1.8/i686-linux/tcltklib.so
from /usr/local/lib/ruby/1.8/tk.rb:7
from (irb):1:in `require'
from (irb):1
irb(main):002:0> Tk::TK_PATCHLEVEL
NameError: uninitialized constant Tk
from (irb):2
irb(main):003:0> Tk::AUTO_PATH.list
NameError: uninitialized constant Tk
from (irb):3
irb(main):004:0> require 'tkextlib/tkHTML'
NameError: uninitialized constant TkPackage
from /usr/local/lib/ruby/1.8/tkextlib/tkHTML/htmlwidget.rb:15
from /usr/local/lib/ruby/1.8/tkextlib/tkHTML.rb:13:in `require'
from /usr/local/lib/ruby/1.8/tkextlib/tkHTML.rb:13
from (irb):4:in `require'
from (irb):4
what should I do?
I want to install it any way. For this i can uninstall and reinstall
all things.Just tell me what to do.?
presently
rpm -qa | grep tcl
gives
tclx-8.3.5-4 db4-tcl-4.2.52-6 tcl-html-8.4.7-2
postgresql-tcl-7.4.6-1.FC3.1
tclx-devel-8.3.5-4
ruby-tcltk-1.8.1-7
tclx-doc-8.3.5-4

Should I erase all the above?
I think problem is that Ruby is not taking the path of Tcl/Tk
extension correctly.
bye
