Thanks. Reviewed to 27d2e1e. Please consider;

• make the collabwrapper changes first in https://github.com/sugarlabs/collabwrapper
• add COPYING files for the LGPLv2 and GPLv3 licenses.

@quozl

• Added the COPYING files
• I didn't understand what changes were to be made in the collabwrapper.
• Also, I didn't understand what the collabwrapper is for? I read the docs then, but what is the collaboration system for Sugar. Looking interesting for sure. Is it the thing that makes participating in other activities possible?

Added the COPYING files

Thanks.

didn't understand what changes were to be made in the collabwrapper.

You made changes to a collabwrapper file; so you ought to be able to explain what changes you made. Make these changes first in the other repository.

didn't understand what the collabwrapper is for

As far as this activity is concerned, it is a Python module. See the other repository for what collabwrapper is.

However, your changes here to collabwrapper are different, please resolve.

@quozl The difference in changes are just of whitespace. I can fix that as well but it's not that critical. Should I?
I think this PR is ready to go, at least.

[quozl]

Yes, I know they are whitespace changes, but you did make them here and did not make them there, so the files won't match, and there's a risk of future patches to collabwrapper not being applied easily here. You can either remove the whitespace changes here, or make the whitespace changes there.

[vipulgupta2048]

@quozl That's what I am trying to reason here, there are no problems left with Collabwrapper/texteditor.py, I checked it again with my editor plugins and with both flake8 and pylint that I used. No whitespace errors found. (Your code has been rated at 8.19/10)
My editor might have automatically removed the whitespace in browse/Collabwrapper/texteditor.py which is modified a little. Here, time package is being imported but the original script in collabwrapper repo has no reference to that. So it's safe to say that we are good. I think.

[quozl]

Looking deeper;

• texteditor.py wasn't necessary,
• collabwrapper.py was out of date,
• placement in a subdirectory made applying collabwrapper patches less automatic.

[vipulgupta2048]

@quozl It's very odd, indeed. If the activity has a maintainer, maybe he/she can work towards improving it.

[quozl]

I did, pushed to your branch, then merged. You're welcome to review.
