Posting to Twitter account using Windows .bat file code - bash

Question

I'm trying to setup an automatic tweet script that runs after a git commit. I'm using Windows 7 have curl available in the command line.
I'm not sure how to set variables with the language windows scripts run and also am not positive about the oauth process.
I have the api key and secret, and also the consumer key and secret but I'm just not sure how to wrap it all together.
Here is a paper clipped mashup of code I'm trying to use as a foundation:
#!/bin/sh
# PATH modification needed for http_post and oauth_sign
export PATH=$PATH:/usr/local/bin
toplevel_path=`git rev-parse --show-toplevel`
toplevel_dir=`basename "$toplevel_path"`
branch=`git rev-parse --abbrev-ref HEAD`
subject=`git log --pretty=format:%s -n1`
hashtags="#code #$toplevel_dir"
tweet=$hashtags' ['$branch']: "'$subject'"'
# truncate tweets that are longer than 140 characters
if [ ${#tweet} -gt 140 ]
then
tweet_trunc=$(echo $tweet | cut -c1-137)
tweet=${tweet_trunc}...
fi
//set vars
consumer_key="mPijnvYpD0sHAY8r*******"
consumer_secret="OWuvuyQeYrT3ToJgyvNdR6baNuDldmTDF5IIJCI************"
access_token="2476143012-ld78CrgnNY3kUmD0QRdvIchXeDC13nO3********"
access_secret="3HTdOlf8jCVzPi5I9usV7rIbGFtM5f****************"
//build oauth
//post data
//example curl code found during research
curl --request 'POST' 'https://api.twitter.com/1.1/statuses/update.json' --header 'Authorization: OAuth oauth_consumer_key="mPijnvYpD0sHAY8r6fkox0KBj", oauth_nonce="OWuvuyQeYrT3ToJgyvNdR6baNuDldmTDF5IIJCIablQbyHA2PS", oauth_signature="Ba6IB8uH2SjtrK8a%2FgZnqCgvIKs%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1346207448", oauth_token="14814762-vvYtBOLX8hBAQ0i0f1k4wxrioG1jOk49MJrqn3myE", oauth_version="1.0"' --verbose -F "media[]=#mack.jpg" -F "status=Test from cURL" --header "Expect: "
Any help at all is appreciated.

Bro, on Windows you should use PowerShell now. .bat is lame!
$toplevel_path = git rev-parse --show-toplevel
$toplevel_dir = Split-Path $toplevel_path -Leaf
$branch = git rev-parse --abbrev-ref HEAD
$subject = git log --pretty=format:%s -n1
$hashtags = "#code #$toplevel_dir"
$tweet = '{0} [{1}]: "{2}"' -f $hashtags, $branch, $subject
if ($tweet.length -gt 140) {
$tweet = $tweet.substring(0,137)
}
$oauths =
'oauth_consumer_key="mPijnvYpD0sHAY8r6fkox0KBj"',
'oauth_nonce="OWuvuyQeYrT3ToJgyvNdR6baNuDldmTDF5IIJCIablQbyHA2PS"',
'oauth_signature="Ba6IB8uH2SjtrK8a%2FgZnqCgvIKs%3D"',
'oauth_signature_method="HMAC-SHA1"',
'oauth_timestamp="1346207448"',
'oauth_token="14814762-vvYtBOLX8hBAQ0i0f1k4wxrioG1jOk49MJrqn3myE"',
'oauth_version="1.0"'
$header = 'Authorization: OAuth {0}' -f ($oauths -join ',')
curl --verbose --request POST -F 'media[]=#mack.jpg' `
-F 'status=Test from cURL' --header 'Expect: ' `
--header $header https://api.twitter.com/1.1/statuses/update.json
command substitution is actually better than with Bash
PowerShell "printf" is cool
arrays are cool
the continuation character ` is too small though, hard to see
