get theme branch main

[c1au6i0]

new_site does't download themes if the name of default branch is not master. People started to switch to main...

blogdown::new_site(theme = "wowchemy/starter-research-group")

It does if the main branch is called master, as in the repo that I forked herehttps://github.com/c1au6i0/starter-research-group.

Well I am not sure if that is the problem or not, but that is a possibility I guess

Hi- if you use ?new_site the theme argument help docs say:

A Hugo theme on Github (a character string of the form user/repo, and you can optionally specify a GIT branch or tag name after @, i.e. theme can be of the form user/repo@branch). You can also specify a full URL to the zip file or tarball of the theme.

So I just tried this and it "worked" (although the exampleSite results in a Hugo shortcode error):

blogdown::new_site(theme = "wowchemy/starter-research-group@main")

[c1au6i0]

Got it, sorry not sure why I missed that in the documentation.

You can specify the branch after @, e.g.,

blogdown::new_site(theme = "wowchemy/starter-research-group@main")

This is documented on the help page ?blogdown::new_site.

That said, I agree it should do a better job to just figure out the default branch automatically. Thanks for the report!

Update: Oh I didn't realize @apreshill had already replied. Again, I'll improve this function so you don't have to specify @main in the future.

[yihui]

Done. The development version should be able to figure out the default branch now:

remotes::install_github('rstudio/blogdown')

[yihui]

Also note that wowchemy/starter-research-group is not really a theme (but a sample site instead), so it won't work with new_site() at the moment. I might be able to figure out how to make it work with new_site() in the future, after I know more about these "Hugo modules" (which is currently still a pain to me).

[yihui]

It should work now:

remotes::install_github('rstudio/blogdown')
blogdown::new_site(theme = "wowchemy/starter-research-group")
