# Find all CRAN package with FORTRAN code
packages <- c()
base_url <- 'https://api.github.com/search/repositories?q=user:cran%20language:fortran'
for(page in 1:100){
  url <- paste0(base_url, "&page=", page)
  cat("Reading", url, "\n")
  repos <- jsonlite::fromJSON(url)
  if(!length(repos$items)) 
    break
  packages <- c(packages, repos$items$name)
}
