Autocompleting ssh, rake, cap command parameters using PowerShell

I have mentioned in my previous posts that PowerShell has excellent and customizabme autocompletion support.
And some awesome plugins like powertab exist to take this functionality to another level.
Here is one easy way you can customize autocompletion easily by writing a couple of lines of code.

Open your PowerShell profile file (for help see here) and create a function with name "global:TabExpansion" in it.
This function basically overrides default autocompletion and sends your values to the prompt. For example for it to read your ssh files and display hosts in it the function would look something like this:

# customized tab expansion

function global:TabExpansion {

  param($line, $lastWord)

  if ($line -match 'ssh'){

    return cat C:\Users\Gaurav\.ssh\config | Select-String '^Host ' | % { if($_.Line -match "^Host ($lastword\S*)" ){ $matches[1] }}

  }

}

Creating a new Flex project:

Open Flex builder and create a new Flex project.

Leave all the options to default and click Finish. A blank project is now created for you.

Using Silverlight with Ruby on Rails

In this post I will be showing a really simple example of creating a Silverlight frontend for a Rails backend. This is what I think will be a three part series comparing Silverlight with Flex.

The steps will be:

1. Creating a Rails application.
2. Creating a frontend for it in silverlight.
3. Creating a frontend for it in Flex.
4. Comparing the approaches taken in both the frontends.

I will try to keep changes in the backend Rails application to a minimum.
