Lists strings that may be required safely with a plain ruby installation
This produces a list of strings such as "set" and "base64" that should always succeed with require… unless there’s a broken ruby installation.
This program provides a script you can run, like so:
$ ruby-builtin-requireables English abbrev base64 benchmark ...
This is meant for use in things like git commit hooks or Rakefiles for providing dependency management hints.
An snippet from Rakefiles I use this in:
builtin_requireables = IO.popen("ruby-builtin-requireables").readlines.map(&:chomp)
# ... define all_requires to be a list of all the strings given to `require` keywords # ... make hashes of gem name = version, for dependencies and dev_dependencies
missing_deps = (all_requires - builtin_requireables - dependencies.keys - dev_dependencies.keys)
if missing_deps.length > 0
puts "There may be some dependencies not listed in project.yml:"
puts missing_deps.join(", ")
end
