Exporting feature

[Sim98B]

Hi, your work is amazing, and I can't stop using it. You've really sparked my interest in playing. It would be great if I could export the analysis results (accuracy, rating, move classifications) so I can use them elsewhere too. Thank you so much

[GuillaumeSD]

Hi @Sim98B, thank you for your kind words ❤️
What kind of export format are you thinking about ? Where exactly do you want to use this data ?

[Sim98B]

I was thinking of using JSON or some other format suitable for exporting mainly the move labels. Right now, I'm doing manual labeling by creating a JSON file containing my games like this:

I retrieve information from the PGN, such as the date and Elo rating, format the moves in the list, and then manually add the classifications, rating, and accuracy. The idea is to aggregate the analyses to create and extract Aimchess-like KPIs; for now, I’m simply looking at the percentage of moves per game. I hope I've made myself clear; I'd just like to avoid manual labeling, especially if the game is very long.

can I work on this

[Sim98B]

Hi @avishek0070 , I've already implemented the main functions in Python and created some functions to automatically generate JSON for extracting small insights. If it might be useful to you, I have a repository—take a look.

[avishek0070]

send the repo

[Sim98B]

https://github.com/Sim98B/ChessAnalyzer

[avishek0070]

Hi @Sim98B this repo is not same as Cheskit Repo,You need to pull the exact main branch code of Chesskit, and then make changes and changes need to be in Typescript

[avishek0070]

Hi @GuillaumeSD I have created a fix for this,also currently chesskit doesnt support chess960 game analysis if you want I can work on that

[GuillaumeSD]

Hi @avishek0070 , I don't know if we will add this feature to this project atm, I don't feel like it's requested enough. If we do at some point, it would not be as a button in the toolbar, since it would take space for a feature that 99.99% users won't use.
Regarding chess960, chesskit doesn't support castling in chess960 games because it relies on https://github.com/jhlywa/chess.js for chess rules and it doesn't support it yet. There is a PR there but it seems stuck. There is no easy solution to this atm so it's on standby for now.

[avishek0070]

Hi @GuillaumeSD
Got it, thanks for the context on Chess960.
I’ll take a look through the repo and see if there are smaller improvements or gaps I can pick up. If there’s anything specific you’d prefer I prioritize, feel free to point me to it.

@avishek0070 Those two are great and not too complex first issues to start with :

[nuttudot-art]

Ye somekind of login system or exporting the games I have saved to database would nice since they dont show If I use another browser (mozilla). Haven't tested If they show on my laptop with the same browser Im using (operagx)

[nuttudot-art]

And maybe option to save those games in to different folders and ability to move them around If needed so I could check easily my games for different openings <3. Also the discord link is not working anymore on the site, do you still have discord channel?
