Re: ANN: Spontini-Editor version 1.12-alfa

[Jan-Peter Voigt]

Hello Paolo,

thank for that hint, I wasn’t aware of it.
I’d delegate the SSL-Question to some docker-compose setup with Traefik and 
maybe Authelia.
Until now I haven’t used Authelia yet and I use another image for the SSL part 
for my own setups, but it is also a setup with  nginx serving as a reverse 
proxy with certs from lets-encrypt.
That way you don’t need to bloat the Spontini image with this Cert-Stuff.

Cheers
Jan-Peter

Re: ANN: Spontini-Editor version 1.12-alfa

[Paolo Prete]

Hello Jan-Peter,

thanks for your contribution!
There's already a docker setup for the editor, similar to yours, together
with other very useful setups (ly2video, fonts etc.), made by Alexis:

https://github.com/jeandeaual/docker-lilypond/pulls

However, it's not pushed yet because we have to find a practical way to
solve an issue which appears in your setup too: the need to use the 0.0.0.0
address with HTTP, which could be unsafe.
It is possibile, with Spontini, to use certs, so to switch to HTTPS and
avoid this issue:

https://github.com/paopre/Spontini/blob/master/documentation/webserver.md

However, this could be a bit cumbersome with docker, because the user would
have to create certs and then push them to the container through some
command. If we find a shorter way to obtain a HTTPS setup it would be much
better.
I don't know if a sort of duckdns plugin can be a solution...
Please let me know if you have any idea about this.

Cheers
Paolo

Hello Paolo,

I really like Spontini and created a docker setup to test it. I just
started it again. It takes some time to build, but then one can use it
from http://localhost:8000/spontini-editor/.

Hi Paolo,

Thanks, I was not aware of it and I'll surely test it ASAP

Hello,

I tested the editor on macOS Catalina, with LilyPond 2.22.0 from unofficial
64-bit app bundles and had no problems.

1) Which browser are you using?
2) Please can you paste the complete log of the SpontiniServer window on
the issues page of GitHub https://github.com/paopre/Spontini/issues (or pm
to my email)?

thanks

If you mean an unstable release, you cannot, since these
aren't built with Cairo yet -- the switch to Guile 2
and the new infrastructure for binaries was already enough
for a single release. So if you want to test it (which
will be very much appreciated if you can report any
problems you find), you have to compile LilyPond yourself
by following the procedure described in

http://lilypond.org/doc/v2.23/Documentation/contributor/compiling

To enable Cairo, you have to configure with

../configure --enable-cairo-backend

and then you run with Cairo using

lilypond --svg -dbackend=cairo file.ly

(if you use --svg, -dbackend=cairo must be last).


> 2) Is there a plan of when it will be included into a released version?

I haven't followed this story very closely, but I guess
it will be included at some point in this development
series. When it will become the default is another question.


> 3) Is it already well working, or is it in unstable/buggy state?

Working quite well overall.

Jean

Hello,

after installation I get an application window at 
localhost:8000/spontini-editor/, but cannot use it:

"Error while connecting to SpontiniServer.“

Did I miss something?

Thanks for these infos.

1) once I download a development snapshot, how can I test it?
2) Is there a plan of when it will be included into a released version?
3) Is it already well working, or is it in unstable/buggy state?

For your information, a new backend for LilyPond has been developed
over the last year, based on the Cairo library, which solves this
problem (it makes PDF output a bit faster and brings SVG on par
with PDF in speed). This is just a heads-up, since it not enabled

ANN: Spontini-Editor version 1.12-alfa

[Paolo Prete]

Hello,

I have published a new version of Spontini-Editor (1.12-alpha): it is still
in the testing phase and therefore not available in the list of releases,
but it is already working and it can be downloaded from the main project
page.

https://github.com/paopre/Spontini

The important features of this version are:

1) support for PDF output, in order to speed up the compilation of scores.
Thanks to the PDF mode, instead of SVG, the compilation time drastically
decreases: once the score has been sketched it is possible to switch to SVG
mode, in order to complete it through tweaks with the mouse.

2) MIDI input: it is now possible to enter notes / chords via a MIDI
device, using the Web MIDI API on both Chrome and Firefox. It is also
possible to insert these notes automatically in the tables for the creation
of piano / cross-staff music.
In this case the notes are automatically inserted in the upper staff, but
they can then be quickly moved to the lower staff (or vice versa) with the
arrow keys of the keyboard (see the image below)

https://github.com/paopre/Spontini/blob/master/documentation/images/midiInput.gif
