many other pdf readers should work, above is a list that I have tested.
For async support (Compiling in background)
Just like any other vim plugin
To start the preview mode:
:StartMdPreview
This will compile your markdown document and open it in one of the above pdf viewers.
If the preview is currently running every save will recompile the document and the previewer will be refreshed.
To stop the preview mode:
:StopMdPreview
Once the preview is stopped the document won't be automatically compiled when saved.
Stick the following in your vimrc, replacing <previewer>
with the name of your preferred pdf viewer.
let g:md_pdf_viewer="<previewer>"
You can make use of the g:md_arg
variable to pass arguments to pandoc. For example, taken from my vimrc.
let g:md_args = "--template eisvogel --listings"
This compiles markdown using the eisvogel template.
