finding binaries / version string #5

some observations of a first test. after installing with

echo 'deb [arch=amd64 trusted=yes] https://lichess-org.github.io/external-engine/debian bullseye main' | sudo tee /etc/apt/sources.list.d/external-engine.list
sudo apt update
sudo apt install remote-uci stockfish

and enabling with http://localhost:9670/ I noticed that the external engine was shown as stockfish 12 not stockfish 15. It turned out that the external engine found was an old one in /usr/local/bin/stockfish and not the freshly installed one in /usr/bin/stockfish. Probably because of the order of these directories in the PATH. Not sure this needs or can be fixed easily.

After removing the /usr/local/bin/stockfish (now having /usr/bin/stockfish found with which), the label shown on the web page was still stockfish 12, probably not updated. I think this got fixed after installing/reinstalling remote-uci and visiting http://localhost:9670/ again. Maybe the version check could be done at always.

Thanks for testing!

I temporarily reduced this repo to a more minimal example provider. It updates the meta data on every startup. Will have to keep this in mind for a more fully-featured provider as well.
