Analysis Board - Set moves with url parameter

[labbeast89]

We can already define in the URL what is the

• FEN
• Side of the board
• Color of the board
  And so on

It would be really handy to have a parameter moves (or line) as someone expressed on reddit:https://www.reddit.com/r/lichess/comments/kollls/is_it_possible_to_pass_a_pgn_line_to_lichess_via/

Let me know if this is possible!

Keep up the good work!

@ornicar I saw your recent commit, can it be used with a FEN starting position? If so how? Thanks!

This feels like a duplicate of #10205, so closing it for now. Feel free to comment/thumbs-up that issue.

As for how to use the current endpoint, you can do something like this:

https://lichess.org/analysis/pgn/1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6

I meant using both FEN and moves at the same time. Something like:

https://lichess.org/analysis/6k1/p5r1/8/3p1q2/2pP2P1/2P1PN2/PP4P1/R1BR2K1_b_-_-?pgn=1..._Qxg4_2._Rd2_Qxf3

So we use the following FEN as starting position:
6k1/p5r1/8/3p1q2/2pP2P1/2P1PN2/PP4P1/R1BR2K1

And the following pgn as moves:
1... Qxg4 2. Rd2 Qxf3

If all you want to do is specify color in combination with the PGN then you can do this:
https://lichess.org/analysis/pgn/{PGN}?color=black
For example: https://lichess.org/analysis/pgn/1.%20d4%20d5%202.%20c4?color=black
