Konsole already has this amazing "URL Hints" feature. You wouldn't have to use your mouse to open the URL's. The idea is extending the same feature to it supports "hints" for any regular expressions. For example, I personally have to deal with a lot of uuid's during the day. They generally look like this: 7b6436b2-005d-11e7-b9c2-f23c91b0d077 The idea is that I'd give this regular expression to Konsole: /^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89AB][0-9a-f]{3}-[0-9a-f]{12}$/i Then, every time I hold the "hint" keyboard shortcut, it would detect those strings as well, and offer them to me to open them. And instead of opening them in the browser, it would just copy them to the clipboard. Konsole can then provide a list of widely known regular expressions by default. For example: UUID Hex Colors ISO Date's ... That'd make Konsole much much more keyboard friendly.
I actually looked into Konsole's source code. It seems that the basis for executing this feature is almost already there through filter chain. There is already an extendable Filter Chain which can take in classes for processing. I think the majority of the work is just adding the UI to manage the list of regular expressions.
I like the idea, considering that you already looked in the sources any change you could also provide a small implementation?
I have not done any cpp programming in many years, so I'd be struggling about it. However, I can try. But I'm not sure if I'll be successful at it.
You can always ask questions, we really need more developers. :)
I will give it a try, but I probably am gonna fail ;)
