The important thing your editor attracted me is the copy and paste function.
other editors doesn't have this.
But the annoying thing is it will be deleted instantly when downloaded by AV software.
Maybe I should close the AV when using it.
You should be able to add an exception in your AV somewhere. Or just don't use it IDC. It's really just a personal tool that I have made available for others if they want.
The format for PUD files is very simple and pretty well documented. Anyone who is capable of basic coding in any language could make their own. I think I spent a couple of hours one evening adding the cut/paste to the editor a few years ago.
The main code for my editor is very noobish, messy and kludgey. I wrote it a long time ago and have added bits into it but never really maintained it, if I was going to do anything public with a PUD file editor it would be a complete rewrite, but there's not a lot of point in bothering to do that in 2018.
I started a project to do a pud editor in ASM on this forum a while ago because people seemed interested, but in the end nobody else bothered contributing anything so the project didn't continue.
