2021.11.01 New version was released: 2.0.0!

This release brings following new features:

Kitty board

Nocheto now support graphical board on kitty console.
(This console is part of most Linux distributions, so you should be able to install it by your package manager.)

kitty board

  • Nocheto can create graphics board from image of size 800x800px (whole board) or 200x100px (two squares).
  • Dependencies on Magick library were removed from nocheto, which increase its portability. Nocheto uses its own image file format now, called nepix.
  • Graphics board can be created just by setting two colors.
  • Board and pieces images can be read from directories under ~/.nocheto/themes/ directory

Stoppable commands

Commands analyze+, play (to end, vs <engine> or <engine> vs <engine>) and replay are running in background now (in a separate thread), and therefore can be stopped by a new stop command.

You can list all stoppable commands by new stoplist command.
(Some other commands become stoppable in the future releases!)

New commands

  • stop and stopstoplist commands (see Stoppable commands above).
  • keepontop command enable clearing console before drawing board, which causes drawing the board always from the top.
  • switchsounds command can now enable/disable sounds.
  • debug command was added, which can enable/disable debugging on the fly.
  • listthemes command list themes you can use with boardtheme and piecestheme command
  • boardtheme, piecestheme, boardwhitecolor and boardblackcolor allows you to change values for corresponding configuration properties, see below.
  • clearboardcolors clears boardwhitecolor and boardblackcolor so the boartheme takes effect.
  • up<< command undo back to the main line

New configuration possibilities

Example of configuration for several engenes
[engine_stockfish] name = Stockfish 14 engine = /usr/games/stockfish [engine_komodo] name = Komodo 10 engine = komodo [engine_gnuchess] name = "Gnuchess" engine = gnuchessu

With this configuration, you can play against komodo by play vs komodo command, or let play stockfish against gnuchessu by play stockfish vs gnuchess command.

Other changes

  • Nochetoclient gets tablebase from nocheto, which decrease the amount of internet requests into the tablabase.
  • board command can now change the board. (It takes the same arguments as --board options).
  • goseconds configuration value affects time used by nochetoclient (in analyze mode) for analyzing one move. Value -1 is used for an infinite search. It is recommended to add goseconds=30 in your client.ini configuration file (use whatever you like instead of 30).
  • play vs <engine> command can switch the engine against which you play.
  • play <engine> vs <engine> command plays two given engines against each other.
  • Revision number is shown as a part of nocheto version now.

Buf fixes

  • fixed evaluation of mate and stalemate positions in nochetodbeval
  • UCI engine is now reconnected only if it is not running

nochetodbload can now delete loaded game. Use --delete-game option.

New features in nochetopgn

This new UTF-8 annotations are now detected: ∞,⩲,⩱,±,∓,⨀,○,⟳,↑,→,⇆,⨁,=/∞,− +,− + and N (for novelty).
