Options and environment variables for where to find external tools #17

Closed HenrikBengtsson closed 8 years ago

HenrikBengtsson commented 9 years ago

Add options and environment variables for where to find external tools such as Pandoc and Asciidoc and utilize these in findPandoc() and findAsciidoc(). The default should be that they fall back to using Sys.which(), but it should be possible to override it (and thereby even disable external tools).

This is actually already implemented:

findPandoc(): R_PANDOC -> RSTUDIO_PANDOC -> Sys.which("pandoc")
findAsciidoc(): R_ASCIIDOC -> Sys.which("asciidoc")
