Bug: Can't install a package without imports

[jrosell]

Here an example:

rix::rix(
  r_ver = "bleeding_edge",
  r_pkgs = c("tidyverse", "digest", "bench"),
  git_pkgs = list(list(package_name = "uwu", repo_url = "https://github.com/JosiahParry/uwu/", commit = "cb20213e6faed74323634c404334c0fbdfdebfaf"))
)
#> Error in strsplit(unlist(imports), split = ","): non-character argument

I assume it's here because {uwu} has no imports.

rix/R/fetchers.R

Line 154 in 287e8bd

output <- unname(trimws(unlist(strsplit(unlist(imports), split = ","))))

Not tested, but here a suggested fix:

if (!is.null(imports) && length(imports) > 0) {
  output <- unname(trimws(unlist(strsplit(unlist(imports), split = ","))))
} else {
  output <- character(0) 
}
