Using Twitter as a build status board

on
Twitter is an ideal medium for creating a build board. Everyone has an account, team members can elect how and when they'd like to be informed, it works on a multitude of devices for the BYOD crowd.

You need a Twitter account, and a Twitter development account so that you can define an application and request the necessary Keys and Tokens.

But once you have this information, you're good to send your first tweets

    $status = [System.Uri]::EscapeDataString($tweet);  
    $oauth_consumer_key = "";  
    $oauth_consumer_secret = "";  
    $oauth_token = "";  
    $oauth_token_secret = "";  
    $oauth_nonce = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes([System.DateTime]::Now.Ticks.ToString()));  

     $ts = [System.DateTime]::UtcNow - [System.DateTime]::ParseExact("01/01/1970", "dd/MM/yyyy", $null).ToUniversalTime();  
    $oauth_timestamp = [System.Convert]::ToInt64($ts.TotalSeconds).ToString();  
  
    $signature = "POST&";  
    $signature += [System.Uri]::EscapeDataString("https://api.twitter.com/1.1/statuses/update.json") + "&";

    $signature_key = [System.Uri]::EscapeDataString($oauth_consumer_secret) + "&" + [System.Uri]::EscapeDataString($oauth_token_secret);  
  
    $hmacsha1 = new-object System.Security.Cryptography.HMACSHA1;  
    $hmacsha1.Key = [System.Text.Encoding]::ASCII.GetBytes($signature_key);  
    $oauth_signature = [System.Convert]::ToBase64String($hmacsha1.ComputeHash([System.Text.Encoding]::ASCII.GetBytes($signature)));  
  
    $oauth_authorization = 'OAuth ';  
    $oauth_authorization += 'oauth_consumer_key="' + [System.Uri]::EscapeDataString($oauth_consumer_key) + '",';

    $oauth_authorization += 'oauth_token="' + [System.Uri]::EscapeDataString($oauth_token) + '",';  
    $oauth_authorization += 'oauth_version="1.0"';  

    $post_body = [System.Text.Encoding]::ASCII.GetBytes("status=" + $status);   
    [System.Net.HttpWebRequest] $request = [System.Net.WebRequest]::Create("https://api.twitter.com/1.1/statuses/update.json");  
    $request.Method = "POST";  
    $request.Headers.Add("Authorization", $oauth_authorization);  
    $request.ContentType = "application/x-www-form-urlencoded";  
    $body = $request.GetRequestStream();  
    $body.write($post_body, 0, $post_body.length);  
    $body.flush();  
    $body.close();  
    $response = $request.GetResponse();
}

Then, you're good to create tweets to suit your needs.

Set-TwitterStatus "Build 1000 has completed with 0 errors"
Set-TwitterStatus "Build 1000 was deploy to OAT in 1m:55s"
