[NTG-context] Re: automatic character comparison

The first line shows different versions text. I wonder whether there would be an automatic way to get the \inframed highlighting with any character that differs from the other column (it might be different, or just missing or being added).

I'm not aware of anything built-in. One way would be to use buffers: you enter your text into two buffers ("left" & "right"); compare them using a script which then modifies the buffers to highlight the changes in red or green; and then \getbuffer the buffers from inside the columnset commands to print them. There's a good discussion of comparison algorithms at the link below, including source code in Javascript (but not Lua, unfortunately). However, Context supports Javascript with \startJScode ... \stopJScode so you could try adapting what's there. https://neil.fraser.name/writing/diff/ Regards, — Bruce Horrocks Hampshire, UK
