parsing options

[vondele]

fishtest sends this option to cutechess-cli / fast-chess:

./fast-chess    -recover -repeat -games 466 -tournament gauntlet\
                -pgnout results-a181cd67-43a0-4d6e-b6b4-98f9b5fa7e7e.pgn\

                -srand $RANDOM  -resign movecount=3 score=600 -draw movenumber=34 movecount=8 score=20\

works with cutechess, but fast-chess has:

terminate called after throwing an instance of 'std::runtime_error'
  what():  
Error while reading option "-engine" with value "option.EvalFileSmall=nn-37f18f62d772.nnue"
Reason: Error; Engine not found:

maybe because of the dash in the filename?

[gahtan-syarif]

or on second thought its probably the dot

        // Strip option.Name of the option. Part
        const std::size_t pos         = key.find('.');
        const std::string strippedKey = key.substr(pos + 1);

std::find_first_of ?

wait, weirdly enough it works for me:

log also shows its inputting the correct setoption

[Engine] [04:55:29.453200] <  5> Engine1 ---> readyok
[Engine] [04:55:29.453312] <  4> Engine2 <--- setoption name EvalFile value nn-ddcfb9224cdb.nnue

[Engine] [04:55:29.453488] <  4> Engine2 <--- ucinewgame

perhaps theres something off with your configuration?

[gahtan-syarif]

im guessing the culprit is actually this

cmd=./stockfish_ee6fc7e38b4aeef44862159215a56d97122f59a0 dir=.\

and the error is incorrectly blaming it on EvalFileSmall as its the last option set for the engine
