Mac Command Line Tool for Solona - Accessible Captcha Reading Service

Solona provides an image to text service for the visually impaired. Images are uploaded and a volunteer reads it and replies with a text translation. This is currently used for translating Captcha images when no audio is provided. Please see the Solona.Net website for account and information detail.

This page has download links for a utility for Mac users to easily upload screenshots and get responses without having to navigate through the Solona website. It was created at the request of one of my friends, and has been approved for use by the development team at Solona.

sendtosolona Version 1.1 - Command line program that takes username, password, and file path/name as arguments and sends these to Solona.Net. If a valid response is received, it is copied to the clipboard. One system beep means it worked. Two system beeps means there was an error.

configuration Version 1.0 - This is an optional shell script that stores the username, password, and the png file directory. Version 3.1 - This is an optional shell script that reads the configuration file and takes the most recently modified png file in that directory, confirms that this is the one you want to send, and then calls the sendtosolona program. Version 2.0 - This is an optional shell script that updates the configuration file.

Don't use any special characters in your path/file name.

The sendtosolona command line tool expects you to provide the absolute path to your file, so:
instead of:

If you get a "Bad CPU Type" error, try replacing sendtosolona with sendtosolona386, which is the 32 bit version. You will need to rename it without the 386 for the script to work.

If you get a "./configuration file not found" error, upgrade to version 3.1 or higher for the script.

Source code for the sendtosolona application (objective c) is available on request.
