Help with a script

JayMan · January 2, 2018

Hi All,

Looking for some help if anyone can provide it.

I run this Twitter Bot. https://twitter.com/OntarioRoads A friend made this script years ago but he has passed and I've been able to keep it running just by sheer luck but I am trying to improve it since Twitter can do 280 char now.

How it works is the below script looks on this website for anything new http://www.mto.gov.on.ca/english/traveller/trip/road_closures.shtml and then makes it into a format like this and emails it out.

Subject: *-NEW-* HWY 401 Westbound Collector(s) [ McCOWAN ROAD - ] - Disabled Vehicle ...21:23:09

Body:

*-NEW-*
HWY 401 Westbound Collector(s) [ McCOWAN ROAD - ] - Disabled Vehicle
Highway: HWY 401
Direction: Westbound
From/At: McCOWAN ROAD
Lanes Affected: right lane and right shoulder blocked
Reason Disabled Vehicle
Last Change: Entered 2018-01-01 21:13

Event Start: January 01, 2018 21:13
====END====

To which then I grab the subject line and feed it into a basic command line windows app I have and tweet it out.

What I am looking to do is increase the info in the tweets now that I can. I think if I can just add more info to the subject line and then tweet that out it would work but I am up for any ideas you may all have to make it better. I don't make any money off this twitter bot you will see there are no ads etc..

I've included a screenshot of a piece of the DB so you can see what all gets populated.
