Formulas in help pages are not rendered on Windows #6

Closed roundnose closed 3 years ago

roundnose commented 3 years ago

I have met the same trouble as described at stackoverflow-66106745.

In implementation of matjhaxr, the formulas in help documentation are not rendered on win 10 platform. What causes this behavior?

wviechtb commented 3 years ago

Indeed, that seems to be some kind of Windows issue (confirmed under Windows 7 and 10). In the recent update to mathjaxr, the MathJax library is included in a slightly different way and that seems to cause this problem.

As a workaround for the moment, you can use Sys.setenv(MATHJAXR_USECDN=TRUE) to force use of the CDN instead of using the locally installed MathJax library.

Also, if you install mathjaxr from the source package (with install.packages("https://cran.r-project.org/src/contrib/mathjaxr_1.2-0.tar.gz")), then it also should work.

Could you confirm that these workarounds work for you?

I will try to fix the underlying issue as soon as I can figure out where the problem is coming from.

Yep! Both of the two treatments work well while the use of CND is slightly slow.

Thanks for confirming. And that's to be expected with the CDN. Ok, for now at least you have a workaround. Will try to fix the actual issue asap.

Thanks again for raising this issue. This should be fixed now in 730b342. Will submit a new version to CRAN soon.

roundnose commented 3 years ago

It is available on CRAN and it is workable on Win-platform. Thank u.

Reopening until I am 100% sure it is working. As far as I can tell, at the moment, CRAN only has the 1.4-0 version as source; the zip binary for Windows is being built. Once https://cran.r-project.org/package=mathjaxr shows that mathjaxr_1.4-0.zip is available, please try again (as will I). Then we can be certain that it is working properly.

wviechtb commented 3 years ago

Ok, confirmed to work now under Windows when installing the binary from CRAN, so closing this for good.
