Hello,

I am writting an extension for firefox for a niche problem. I want, when in a study or in an analysis board, get the current fen to be fetched and copied to clipboard.

This would permit me to create anki notes from position I want to keep informations about (in majority, remember what I did wrong).

I see there is a FEN displayed underboard but I can't find a way to copy it without me having to click onto the button.

I am not a dev in the first place but I have an embryonic of something but is it normal to have to develop a JS beast just to fetch the FEN of the currently displayed board ?

We don't want all the features

Adding lines of code to a program is like adding weight to a plane. It better be worth it.

#

If Lichess starts adding every single feature user wants it's gonna be unmaintainable

#

And automatically copying the FEN to the clipboard isn't a feature a lot of people want.

#

But you can always make an extension.

#

Maybe try with AI assistants first if you don't know anything about coding, but it'll be hard. If you already know JS programming it should be quite easy.

I am doing. But cant someone just explain how the fen is fetched and displayed on a url like https://lichess.org/gameID/black#23 for example ? I inspected the DOM and all stuff and I can see at some point one WSS call. This call is unique and fetches all the PGN data plus the list of ply/fen but I can't find the wayt it then shows up in the FEN input tag

#

(and I do not want lichess implementing something wich is obvisouly my need huh)

DO NOT manipulate the WebSocket directly. This WILL ban your account.

#

Just fetch the FEN from the input box.

#

why would I be banned in the analysis or study board ?

#

I am not in a live game, never

#

It is easier to fetch the FEN from the FEN share box under the board with some JS.

#

Also I'm not sure if the WebSocket uses FEN, they might use a more compact and efficient format.

Ok, I won't risk my account for that. Will try another way. Thank you.

I guess if you give the AI the page's source code and maybe a screenshot of the page, it should figure out something working after a few iterations? Worth a try at least

Maybe, but most websites have extremly complex partially obfuscated HTML
