Re: [Frescobaldi] convert-ly don't work in 3.0.1 in Windows

[Federico Bruni]

Hi Anders

I confirm the problem on Windows 7.
Detailed versions:

Frescobaldi: 3.0.1
Python: 3.5.2
python-ly: 0.9.4
Qt: 5.8.0
PyQt: 5.8.1
sip: 4.19.1
poppler: 0.52.0
python-poppler-qt: 0.24.2
OS: Windows-7-6.1.7601-SP1

I wonder if any Windows user using Frescobaldi 3 can confirm it. That's 
why I've added lilypond-user in Cc.

My **guess** is that Frescobaldi is trying to use the bundled python3 
to run convert-ly (which is a LilyPond file) and this is going to fail. 
It does even on Linux:

$ python3 /usr/bin/convert-ly /home/fede/tmp/lilypond/converting.ly
Traceback (most recent call last):
 File "/usr/bin/convert-ly", line 52, in <module>
   import lilylib as ly
 File "/usr/share/lilypond/2.19.82/python/lilylib.py", line 238
   print log[0]
           ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean 
print(log[0])?

The best fix would be make LilyPond convert-ly work on python3 as 
well...
Even though Frescobaldi should handle better this kind of errors and at 
least print some information instead of being silent.

Best
Federico

In the meanwhile, you may install the latest Python 2.7 (put a tick to 
add python to PATH) and run convert-ly in PowerShell. See for example:


PS C:\Users\fede\Documents> python.exe 'C:\Program Files 
(x86)\LilyPond\usr\bin\convert-ly.py' .\convert-test.ly
convert-ly.py (GNU LilyPond) 2.19.28

convert-ly.py: Processing `.\convert-test.ly'...
Applying conversion: 2.17.0, 2.17.4, 2.17.5, 2.17.6, 2.17.11, 2.17.14, 
2.17.15, 2.17.18, 2.17.19, 2.17.20, 2.17.2
.27, 2.17.29, 2.17.97, 2.18.0, 2.19.2, 2.19.7, 2.19.11, 2.19.16, 
2.19.22, 2.19.24, 2.19.28


\version "2.19.28"

}
