This article is part of the Scripts series.

Creating en and em dashes from typewriter hyphens

This script is a stripped down and modified version of Autoquote.py.

Instead of converting typewriter quotes to typographic quotes, here we want to set up a system so that we can type and enter '-' (a single hyphen) when we just want a hyphen, '--' (2 hyphens) when we want an en-dash, and '---' (3 hyphens) when we want an em-dash. If you have something like '----' (4 hyphens) you'll probably end up with an em-dash followed by a hyphen.

There are no dialogs except for the message box at the end.

USAGE
 
You must have a document open, and a text frame selected.
There are no dialogs. The presumption is that you have encoded a single
hyphen to mean a single hyphen, two hyphens to mean an en-dash, and three
hyphens to mean an em-dash.
