lang params use Sys.getenv("LANGUAGE") result?

[mrchypark]

how about use lang params Sys.getenv("LANGUAGE") ??

That would work, but on a general basis, I prefer not to mess with environment variables :)

Any reason this would be better than the current implementation?

Sys.getenv("LANGUAGE") is already used variables. that's why I suggest.

[ColinFay]

Ah, that makes sense indeed!

I thought you were suggesting to ask the user to set an environment variable or to set a variable with a function.

We should make it optional though, I'm not sure it's set on every machine.

get_sys_lang <- function(){
  if (!is.null(Sys.getenv("LANG")) && Sys.getenv("LANG")  != ""){
    gsub("([^\\.]*)\\..*", "\\1", Sys.getenv("LANG"))
  } else {
    invisible(NULL)
  }

Also, it should also be possible for the user to prevent the use of the env variable
