FREQUENTLY ASKED QUESTION
How does it work?
GNU sed in fact offers quite beneficial debugging user interface, attempt it yourself with– debug flag. The user interface is not interactive and I desired something closer to conventional debugger. I’ve composed something here.
Does it actually work?
Depends. Sed really does not inform me which line number is it presently carrying out, so I need to replicate parts of sed to think that. Which may not be bulletproof. It definitely worked excellent enough to debug tetris without problems.
Why sed??
Sed is the best shows language, particularly for chart issues. It’s plain and basic and does not mess your screen with ineffective identifiers like if, for, while, or int. Considering that it does not have things like numbers, it’s really basic to utilize.
Why?
I wished to program in sed however it did not have great tooling approximately this point, so I needed to find a solution for it.
Why?
Due to the fact that it’s the basic stream editor for filtering and changing text. And somebody composed tetris in it!
What is the roadmap for future updates?
