While surfing on net I came across a javascript library(animator.js) based on prototype library written by Bernie Sumption.

I found this library a bit interesting. One that appeals me is the ability to define start state and end state through CSS

As far as I know there are very few people working on RubyOnRails in India. Vinayak solutions Pvt. Ltd. is doing great in this field. Recently Manik Juneja (Director) attended the Rails conf. Landon and last week traveled Colombo to train a team of web programmers on Ruby on Rails.

Tab completion in irb

Oct 7th

Posted by Akhil Bansal in irb

5 comments

irb has tab completion support, you need to activate this by requiring ‘irb/completion’. You can load it when you invoke irb from the command line:


% irb -r irb/completion

Or you can load the completion library when irb is running:


% irb(main):005:0> require 'irb/completion'

If you often use tab completion then:

Linux users: Can create an alias in .bashrc by following these steps:

  • % vi ~/.bashrc
  • add alias irbtc="irb -r 'irb/completion'"
  • % source ~/.bashrc

Windows Users: Can create a file named irbtc.bat in your windows\system32 folder as irb -r "irb/completion" the file content.

<
Now you can run irb with tab completion support by:
% irbtc

Example:

% irbtc
irb(main):001:0> st="this is a string"
=> "this is a string"
irb(main):002:0> st.lentab
irb(main):002:0> st.length
=> 16
irb(main):003:0> st.uptabtab
st.upcase st.upcase! st.upto
irb(main):003:0> st.up

Sep 13th

Posted by Akhil Bansal in ROR

If you are not interested in installing a plugin just for one method(state_select) then You can put state_select.rb file in you rails lib directory. And include state_select.rb file in your controller where ever you want to use state_select method.

The url for state_select.rb is http://github.com/bansalakhil/stateselect/tree/master/lib/state_select.rb
Feedback please….

Plugin: state_select, generate drop down selection box for states

Sep 12th

Posted by Akhil Bansal in ROR

39 comments

I have wrote my first plugin(state_select). This plugin allows to create drop down list for states, same as country_select method in rails. I know this is not a big deal…

UPDATE: Curently it can generate state list for India, US, Canada, Australia, Spain and Uganda(default is US).

Usage:

state_select(object, method, country=’US’, options = {}, html_options = {})

Return select and option tags for the given object and method, using state_options_for_select to generate the list of option tags.

state_options_for_select(selected = nil, country = ‘US’)

Returns a string of option tags for states in a country. Supply a state name as selected to have it marked as the selected option tag.

NOTE: Only the option tags are returned, you have to wrap this call in a regular HTML select tag.

github URL: http://github.com/bansalakhil/stateselect/tree/master

Install plugin by

script/plugin install git://github.com/bansalakhil/stateselect.git
