[sage-devel] Re: Characteristic classes on manifolds

Thanks for your interest! :) I started the ticket right away (to be honest, it took some effort as newbie). I already finished the code, yet the first push will take some time. I need to create the doctests, first. Unless you say it's not necessary for

[sage-devel] Re: Characteristic classes on manifolds

Dear MJ, Also if you plan on including your code in Sage (which it sounds like you are, +1!), it would be a good idea to break the code into smaller pieces to help facilitate and easier review. For example, the algebra itself can be one ticket. Feel free to also cc me (by using tscrim) on

[sage-devel] Re: Poll: set online=True as the default for threejs viewer

The CDN fallback only applies to IPython/Jupyter notebooks, not plots generated at the command line. Notebooks need to be run in a local server, and the local server will always know how to find its files. The fallback will only be activated if the notebook is moved to a remote location, and

[sage-devel] Re: Poll: set online=True as the default for threejs viewer

https://trac.sagemath.org/ticket/27575 addresses this by fixing an apparently already existing "fallback to the online CDN" and claiming that this discussion here becomes moot. But I think what the discussion here tried to address is that it is bad for a local install of Sage to silently fetch

Great! So, the next step is cloning sage to my local repo and connect git to the trac server, right? Are there some important things I have to take care of? Am Sonntag, 31. März 2019 11:40:01 UTC+2 schrieb Eric Gourgoulhon: > > Hi, > > Le samedi 30 mars 2019 19:03:27 UTC+1, MJ a écrit : >> >>

Re: [sage-devel] Re: Problem with wedge of unnamed diff forms on non-parall. mfds

PS: if you have SageMath 8.7 installed and want to use the fix introduced in https://trac.sagemath.org/ticket/27576, it is quite easy: simply open a console at the SageMath root directory and type: git remote add trac git://trac.sagemath.org/sage.git git checkout -b wedge_fixed git pull trac
