External API access

[jvsteiner]

Hi - I would like to use this library to implement opening explorer type functionality, by connecting the board, in Edit mode, to a back end server which knows opening moves, and game outcomes - typical opening tree type information like you can see on Lichess or chess.com.

It doesn't seem, however, that I can get the current FEN string out of the object returned by PGNV.pgnEdit() - which, strangely, seems to be null. Is there any way to expose a programmatic api, for getting the current Fen, or passing in a move from an external integration, rather than visually through the UI? This latter capability would allow me to click on a move in the database results, and have that move made in the UI.

Maybe there is already a way to do this, and I am missing it?

Thanks

just an observation - after looking at the code a bit, it seems that somehow the GLOB_SCHED.schedule function, which I believe has to do with the internationalization features, prevent the exposure of the usual pgnBase public api. Therefore it should be fairly simple to just prepare my own instance, with the same initialization. I have hacked a bit, on exposing a slightly different api, for the use case I described above. When I get it done, I will PR you, which, you can take or leave as you see fit.

Thanks very much for this very excellent, and well documented project.

Thank you a lot, I will check your PR on the weekend. But great when you could help yourself!

See the ticket #174 which is a necessary pre-requisit to implement a public API. Currently (as you have noticed), no return value is given to the caller.

have a look at modules/pgn-viewer/examples/tickets/ticket171.html that shows how to use your function manualMove to play from the outside. Hope this is what you had in mind.
