BUG: Error opening Book -> SetParameters dialog

[SuperNose]

I've tried to recognize a Russian lyrics based on the forum feedback here and added to the org.audiveris.text.Language.defaultSpecification value "+rus". Afterwards I cannot longer open the Book->SetParameters window, it gives me:

Hm, now also after I've removed the "+rus" suffix, I can no more access that "Set book parameters" menu-item, although I've reopened the .pdf file freshly, I've restarted Audiveris and even reinstalled it. Seems like there is some still-persisted option somewhere.

Error in BookParameters java.lang.NullPointerException: Cannot invoke "String.trim()" because "spec" is null

I've of course downloaded the RU-trained data from here

Quite frustrating, I can't open that dialog now no matter what; and instead of spending the Sunday with music, I'm analyzing the log-files 😂. But the app is really nice, kudos to the author, unbelievable it exists - I would be glad to help somehow, just tell me how 🙂!

[hbitteur]

Which Audiveris are you using? The installed one (on Windows, the master branch) Or the one built on your own (from the development branch) And which OS too?

[hbitteur]

There is a bug in the handling of book parameters. Something I discovered yesterday by chance. I can easily push a fix on the development branch I guess you are on the development branch, because this is where the bug on book parameters was introduced a few days ago.

[hbitteur]

I just pushed a fix on the development branch. Could you pull and rebuild? And tell me if it's OK now...

[SuperNose]

I've used the Win-Installer "Audiveris_Setup-5.3.1-windows-x86_64.exe" provided at your "Releases" Page, it's dated July-2023. So I didn't build it myself - and in this moment I can't, although I would love to 🤦‍♂️😖. PS: I've tried yesterday quite a lot more with a quite simple music-sheet and was not able to add the score staff/stave to the unrecognized area. Somehow the tool has quite problems with it and although I'm a senior SW architect and play a bit guitar and sing, I was totally lost and gave up 😁!

[hbitteur]

@SuperNose I'm trying to reproduce your problem. For this, I just installed Audiveris using the .exe available on the Releases page, as you did. Then, I made sure that the system environment variable TESSDATA_PREFIX was defined and pointing to the tessdata folder where I put the Tesseract language files. I downloaded the rus.traineddata file to this tessdata folder.

Then I launched Audiveris, using Windows start menu. The Help | About menu gave me this:

Then I could use Book | Set Book Parameters to set the language selection to eng+rus:

And things were OK. I can't reproduce your problem.

When you say:

I've tried to recognize a Russian lyrics based on the forum feedback here and added to the org.audiveris.text.Language.defaultSpecification value "+rus"

It is not clear to me how you proceeded:

• have you manually modified the constant using -option org.audiveris.omr.text.Language.defaultSpecification=rus
• have you gone through the UI interface (using Book | Set book parameters)

I must reproduce your problem, otherwise I won't be able to help you.

[SuperNose]

Book | Set Book Parameters did not show me such options at the beginning, when it was possible to open that dialog: it was empty and I was a bit confused, what´s that option for, when empty.

No, I did not modify the options/settings manually, but as you´ve described via the UI.

Is there any log-file I could send you? Or a TRACE-flag I could increase so it can generate a diagnostic log for sending to you?

Reading the stack-trace, the spec is null, so when you look into the sources, the reason should be clear for you (and you're faster in your code than me ;-)!)

Tell me pls how to proceed: the tool looks amazingly complex and I'm happy to send you any more information which makes it a bit more stable 👍!

[hbitteur]

To get us out of this dead end, I have just published a "pre-release" 5.4-alpha. You can grab the Windows installer here Please install, and tell me how it goes on your side.

[SuperNose]

No crashing now, I can reach that book-settings menu from the alpha version 🙂, TY 👍!

PS: Now I'm left with the more gentle user-challenge: the app won't recognize fully my song (the score stuff was skipped in the beginngin); I've checked the user-docs (for level Einstein skills 😁) how to force/repair the recognition and could not solve it so far🤦‍♂️
