Many years ago I tried it, but didn’t really read up on it. Wanted to back up my Pi’s sdcard while the system was running. I even fucking named that script “online-backup”.
Now every time I ran that, after hours, I noticed my Pi was crashing, and never booted back up. I used chinese sd cards so I blamed it on them.
But this happened multiple times, just to learn I was using dd absolutely wrong.
dd was always a scary utility to me, and still is. I fucked up things with dd, regardless I quadruple checked everything 😅
but to answer the question; it’s possible, but you really need to know what are you doing.
NVU, Dreamweaver were tried to be like this. Only thing that wysiwyg’ing HTML isn’t that easy as one might think, especially nowadays where thousands of web css frameworks exists and every structuring is done via divs.
You could make your own framework, or select/import one you like, but then the app will have way too much parameter, which needs to be configured by the user. It would be a really neat power tool, though.
ps.: Funny thing I was just thinking about wysiwyg editors in the recent days 😅
I don’t know if this memory of mine is real, or just a (day)dreaming or my brain just fucks with me, or just too much acid, but I clearly remember lots of years ago I opened GIMP and the splash screen had this fox IN A FUCKING GIMP SUIT!
