OK, published it warts and all, spotted one or two issues in the blog article but right now I am burned out on a Friday night and I still have two episodes of Start Trek Discovery to get through and latest Raised By Wolves,....
I still say 'Thanks Paul' though because writing this has cheered me up as to how well I am getting to know Mercury...I never thought I'd make it this far!
All the best, thanks all once again.,

Seems to be working well for me. Today I will finish up the blog post, upload a new GitHub project with the offending code and then... just maybe I will make a small YT video... I've always held back because, being from the West-Country (Devon, not SW London) I hate the sound of my own voice, something of a barrier to making commentary coding content. At age 56 you'd think I'd given up caring but obv. not.

This is why software is art, not engineering, for me it is anyway.

>>> ...in one of your videos you mentioned something called 'err' which you said puts errors into the source so you can read it. I thought that was such an elegantly simple idea I immediately chose to write one for nano and integrate it via the external formatter command. Nano, with a hand rolled syntax file based on the prolog one, is my editor of choice now for Mercury, and Kitty.app, the BEST terminal emulator I've discovered.

>>> In the next day or so I will push the code to github, publish the post and reveal all! TBH I could have achieved the same thing in a few lines of python code but...that's day job stuff, and besides I am so utterly into Mercury that I don't really need much of a reason to go off on a tangential hacking spree with it!
