Seeking various 'utility functions'

[guyhaw]

Would appreciate help in finding utilities to:

a) convert from .pgn LAN to list of (position + chosen-move-from-that-position) ... preferably handling multiple games per file, and

b) to check that a list of moves are all playable from a given FEN position

thanks in advance - Guy

Rémi Coulom's pgn2epd writes the chosen move as bm:

Tim Foden's pgn2fen writes chosen moves as pm:

PGNposition by Koundinya Veluri creates pm annotated EPD.

Crafty's epdpfdr will detect any errors in an EPD record.

As a related note, my friend Les Fernandez has written a utility that will take an EPD record and turn all of the pm, bm, and pv fields into the resulting (forward) EPD records.

So that {for instance} this record:
rn1qkb1r/pbp2ppp/1p2p3/3n4/3P4/P1N2N2/1P2PPPP/R1BQKB1R w KQkq - acd 24; acn 3067947357; acs 410400; bm g3; c0 "Analysis by Rybkav2.3.2a.mp.x64 @10800sec@3.0GHz@4threads W512MB hash"; ce 7; pm Bd2 {92} Nxd5 {3} Qa4+ {8} Qc2 {591} e3 {367}; pv g3 Be7 Bg2 Nxc3 bxc3 Be4 O-O O-O Ne5 Bxg2 Kxg2 Nc6 Nf3 Qd5;

is transformed into this:
rn1qkb1r/pbp2ppp/1p2p3/3n4/3P4/P1N2NP1/1P2PP1P/R1BQKB1R b KQkq - id "NM(pv)-1a"; pv Be7 Bg2 Nxc3 bxc3 Be4 O-O O-O Ne5 Bxg2 Kxg2 Nc6 Nf3 Qd5;

Thanks Dan. Forgot to specify that the chosen-move shown after the FEN position should be in LAN rather than SAN. Is that possible? Thanks. g
