I've made a 1.0 release. See the first post for details. The major improvements are a new friendly greeter dialog, built-in beginner tutorials, undo/redo when editing, and post-game IGS chat directly in the board window.

The bump to 1.0 indicates that this now really is reasonably feature-complete, and it seems stable in everyday use. However, I still have some ideas for the future: half-finished code exists for direct online play without a server, and a new IGS observer window that can switch between multiple observed games, with clickable previews. These might make it into future versions. Other ideas include a built-in beginner bot, and a tsumego module.

bernds, thank you very much! KataGo works 13x19, 4x19, etc.

I choose a game against 13x19 KataGo, then I play. How to start a new game without restarting the program?

For a moment I didn't know what you mean, but I'm guessing the problem is that you used the "Play against the machine" button in the greeter dialog and that got closed? In previous versions q5go didn't have the greeter and started by showing the IGS client window, and that one sticks around when you open board windows. So you can work around the issue for now by choosing "Play online" and then use the client window as before.

I'll make a note to add something like a "Restart game" option for engine games.

Can I configure two programs for playing with each other? for example KataGo - KataGo 19x13?

Yes, it's a menu option in the client window (which used to be the main window). I still need to find a good way to expose these lesser used options in the greeter dialog.

big request, you can give an example of how to do it!
edit: I found! it was where I did not expect! I am happy as a child! thank you very much! I am so tormented with Sabaki
if so: play online or a match between two programs?

I don't understand the last question - was that part of the original problem where you couldn't find the option? The "Computer vs computer" menu item runs a game, or a multi-game match, locally between two engines. Nothing on-line is involved.

To see the client window, you must click the "play online". I didn’t find another way.
I suggest adding a "Computer vs computer" to the “play online” window to make it clear how to launch this. or add the window "Computer vs computer"

I installed qt5 creator manually

I managed to install on Ubuntu 18.04, but setting up Qt5 was a painful process. You need to make a qt.conf file to tell the build tools where to find your Qtcreator files. See vstepaniuk's answer at https://unix.stackexchange.com/question ... -for-qmake

On my system, I created ~/.config/qtchooser/qt5.12.5.conf with the following two lines:

(change /opt to your install location, and 5.12.5 to your version number)

and then I was able to build q5Go by typing these three lines:


I did this a few months ago, so I can't remember if any other steps were needed first. Hope this helps a bit.

on boards larger than 25x25 after "z" some symbols. can this be changed? KataGo version released with support for boards up to 29x29:
https://github.com/lightvector/KataGo/r ... 3.5%2Bbs29
the game starts, but after several moves - an error. maybe because of the coordinates after "z"?

Yes, that isn't supported right now. I'll look into it.

I was exhausted from waiting for a version with support for large boards. I’m happy to be a beta tester, if necessary

Well, I kind of wanted to add a few other things before a new release, but I've now made a 1.1 release on github. Enjoy!

bernds My gratitude to you is as great as Fuji!!!

Actually I didn't really consider saving and loading such SGF files - there's a comment in the source that suggests I saw inconsistencies in other programs and decided to disallow anything > 25. So that's a gap in version 1.1 - you can still play these against the computer.

maybe saving and loading sgf files implement as on KGS and in MultiGo? http://www.ruijiang.com/multigo/
37×37 http://files.gokgs.com/games/2012/7/22/ ... link38.sgf

EDIT: I checked, MultiGo loads without errors sgf(37x37) from KGS, and vice versa (CGoban loads without errors sgf from MultiGo).
Lizzie and Leela 0.4.6 uses the same format sgf for boards over 25x25 (I checked on 29x29)

q5go-1.1 saves sgf up to 29x29, using in addition "{", "|", "}". but does not load. I found a temporary solution - in sgf in a text editor, you need to replace these characters with "A", "B", "C". The resulting sgf opens without errors in MultiGo, CGoban, and Sabaki!

In FF[4], the latest version of the SGF standard (since 2006?), it seems to be explicitly documented how to continue beyond size 26 (sgf does not skip the "i"), all the way up to board size 52:
https://www.red-bean.com/sgf/go.html#types

So perhaps the inconsistencies you saw were either from other programs not conforming to the standard, or from choosing to implement a pre-FF[4] version of the standard? I do think there are quite a few SGF parsers that don't quite conform to the standard though which is maybe what you noticed... Go software in the wild is a bit of a mess sometimes. It's hard to get all the corners exactly right, good chance my code in KataGo doesn't either.
