Rating bar

[waldomiro dias machado junior]

Picochess is wonderful, congratulations to all the programmers! One suggestion, if possible: add the option to have the rating bar like Chess Dojo's, it's incredible! Thanks, Waldomiro.

Ok. Good. Now, your best chance of connecting consistently to the Chessnut Air is to start the Pi then immediately turn on the board (this just ensures the board led is still flashing blue when PicoChess starts looking for it). From experience, if it doesn't connect, turn both the Pi and the board OFF and start again.

Hello Randy,

I was only able to connect my Chessnut by downloading the PicoChess 3.4 image with the fix; the command didn't work for me. 

Thank you very much.

It is something that I have in mind and I have done several tests, but it would only be when analyzing the webserver's stockfish. I haven't moved forward because I don't know the acceptance it would have and seeing that there is a tendency towards minimalism...

[Antonio]

would it be good like that???
Although the usefulness that I see is when analyzing with the smartphone, it is not necessary to slide the screen, because with a larger screen, 

it is repeating the information that the engine already shows.

I keep trying...

Hello Antoni (and others)

Should I open an issue and create a branch where this can be tested as part of the V4 code? If I open a branch you can place the code there for testing or?

BR, Johan

[Antonio]

Estoy fuera de casa, esta noche lo subo a github para probar. Se modifican los archivos web como los de la presentación del motor anterior.

I'm away from home, tonight I'll upload it to github to test. The web files are modified like those in the previous engine presentation.

There is now a issue 101, to do these modifications in that branch do something like:

git fetch origin git checkout 101-rating-bar

Note, nothing done there yet, just a branch created which is currently same as master branch.

BR Johan

[Antonio]

I have uploaded the complete webserver folder to github in branch 101.    Is it okay like this?

[Johan Sjöblom]

I rebased it and created a PR, so anyone can now test the branch or read what the PR would change. Its basically additions...

https://github.com/JohanSjoblom/picochess/pull/102

Test and comment in the issue or in the PR. You can also review the code in the PR and comment.

Interestingly, if you are on the master branch and run an update, it doesn't update the other branches. I did an update, then had to use 'git pull' after using 'git switch':

pi@picochess:/opt/picochess $ git switch 101-rating-bar
Switched to branch '101-rating-bar'
Your branch is behind 'origin/101-rating-bar' by 2 commits, and can be fast-forwarded.
  (use "git pull" to update your local branch)
pi@picochess:/opt/picochess $ git pull
Updating fe9b1302..08f3aeab
Fast-forward
 web/picoweb/static/js/app.js | 53 +++++++++++++++++++++++++++++++++++++-------
 1 file changed, 45 insertions(+), 8 deletions(-)

I guess that's normal. My question would be, if I use the menu now to update v4, will it be the current branch that (only) gets updated?

Randy

[RandyR]

It appears that if you have never switched to a different branch (e.g. 'git branch' only shows 'master') if you have done a 'git pull' (on 'master') and then 'git switch' to a desired branch, it will be up-to-date. This makes sense as you wouldn't want git to make changes to your local branch if it's different from the remote repo. It's a complicated and powerful system.

[RandyR]

However, if you are not on the master branch and do an update, it will fail (at least for a git switch to a different branch):

WARNING: You are on branch '101-rating-bar', not 'master'.
Skipping update to avoid interfering with work on another branch.
Backup completed at: /home/pi/pico_backups/current

[Johan Sjöblom]

At the moment the update script has a protection so that if you are not on master branch it will not update. This is what you now experienced. Working on branches means you have to manually switch to the branch and manually do git pull.

[Peter Eggen]

Is there any info available on how to test this? I have updated Picochess using the Menue System->Power->Restart and Update Picochess but not seeing it?

[RandyR]

I believe these steps should work via ssh or locally:

cd /opt/picochess

sudo systemctl stop picochess

git fetch origin

git checkout 101-rating-bar

git pull

sudo reboot

Switch back to master before updating via the menu:

cd /opt/picochess

sudo systemctl stop picochess

git checkout master

sudo reboot

<update via menu>

Or, just update using the terminal:

cd /opt/picochess

sudo systemctl stop picochess

git pull

sudo reboot

Note: instead of rebooting you could just restart PicoChess:

sudo systemctl start picochess

To refresh the kiosk web browser in an attached display you can use:

DISPLAY=:0 xdotool key F5

or press F5 on an attached keyboard.

To see the analysis bar, press the ANALYZE button on the ENGINE tab in the browser.

Thx, worked perfectly

[Johan Sjöblom]

For those that now do git pull (which is the only way to update when you are testing a branch like the 101):

There is now more information in the System -> Information menu: In addition to version (like 4.1.4) there is now also "Update info" and "git info". If the git info does not start with "git:" then the system is not updatable and it means you are on a branch, tag, or some specific commit... As said, the only way to currently update a branch is to switch back to master, and then you can do an update from the menu. If you tried the update on a branch the Update info will show failed. Note that the update info is meant for "normal" non-development users so it will only show when you last updated pico from the menu. If you do your own "git pull" then it will now know that you have updated.

Currently this update and git info is only updated upon starting picochess... So if you manually switch to master branch on a terminal a "still running" pico will show old git info as it was when it started... So there are some improvements that could be made but at least now there is information available for users without an external extra screen. If you do have an external screen you can run the info scripts yourself (without sudo) at any point to get the fresh info:

> ./check-update-status.sh
or

>./check-git-status.sh

These are the two scripts that show the information in the System -> Information menu. So by changing the scripts we can improve the info.

Obviously you can simply also do "git status" instead of the check-git-status.

Let me know when you think this "rating bar" is good enough to be taken into master branch and I can merge. If you have received an invite to be a developer you can mark it as approved to indicate that. With 2 approvals anyone can merge (typical rule that I use). Before merging one would need to check for the need to rebase the PR to avoid conflicts if something has happened on the master branch.

BR, Johan
