RM2 support? about remy HOT 11 CLOSED

Hi @mefistoso I can help you with that but would you mind opening a new issue for this? Your question is not related to RM2 support...

from remy.

I checked local method with Remarkable 2 (have a separate SSH backup script), and it works. The only couple of issues

• one notebook out of few isn't opening and the app gets unresponsive when I try to.. I'll try to debug this
• pdfs aren't opening, but it's more likely to be some poppler/QT issue

@karlicoss I answered your question in #8

It should work in principle, but I cannot test it first hand.
The best performance in my tests is obtained using the rsync method which requires installing rsync on the tablet.
For that, you need to compile rsync for the correct version of the OS/chipset shipped with RM2.

Thanks! Much appreciated.

When I try to run python remygui.py wifi (wifi is rsync), I'm getting the following error complaining it doesn't find a templates.jsonfile:

File "/home/user/Downloads/software/remarkable/remy/remy/remarkable/filesource.py", line 372, in __init__
    with open(self._local("templates.json", branch=TEMPLDIR), 'r') as f:
FileNotFoundError: [Errno 2] No such file or directory: '~/remarkable/rsync/templates/templates.json'

Not sure what this templates.json file is supposed to be or where to get one to adapt. FWIW my remy.json config file is at https://gist.github.com/mefistoso/c2b2ab081ecf1949a4af3fe3765a412b

@karlicoss thanks so much for testing it!
Let me know if you find bugs.
Unfortunately reMy is still quite unfinished, I am planning to work on it but I have very limited time.
Which OS are you on? I could provide binaries to see if the poppler/QT issue is resolved.
(I also added new instruction in the README on how to install the stubborn python-poppler-pyqt5)

@bordaigorl No problem! Thanks for your time spent implementing this :)
I've moved in a separate issue, since it seems irrelevant to RM2 support: #7

from remy.

@karlicoss regarding unresponsiveness: a common reason for inefficient rendering is the heavy use of eraser.
I know it sounds stupid, but the eraser is really annoying/inefficient to render correctly. This is why reMy offers various methods to render it. If you set the eraser mode to ignore for previews you'd probably get those notebooks to display normally (although some details of the rendering might be off). See the Readme for details.
To my knowledge, none of the other exporters render the eraser accurately when exporting to vectorial form (most would be equivalent to reMy's ignore mode).

If you have any idea on how to make that more efficient I'm all ears!

from remy.

Thanks, indeed, setting it to ignore helped!
I guess in theory it's possible to detect when the file takes too long to open and suggest this setting to the user. Or maybe, always open in ignore mode first, and only after that try to apply the more accurate setting (but this might get too complicated).

I didn't quite understand from the readme (and from a brief look at pagerender.py), what's the core cause of slow erasing? Is this because without eraser drawing is relatively straightforward -- you need to draw the layers from bottom to top; whereas the eraser acts on all the layers simultaneously? Or is it because it's not a 'native' operation in QT canvas, and you have to 'subtract' the strokes?

I think this can be closed as RM2 works fine
