MixScript
A build utility that allows you to to use mix packages in an elixir script.
Example
Let us say, you have a file at ~/scripts/elixir_curl.exs
mix_dep {:httpotion, ">0.0.0"}
if args == [] do
IO.puts "invalid args"
else
IO.inspect HTTPotion.get(hd args)
endYou can run the following:
# compile our elixir script
mix_script compile ~/scripts/elixir_curl.exs
# run it with args
~/scripts/elixir_curl http://google.com
> %HTTPotion.Response{body: "<HTML><HEAD><meta http-equiv=\"content-type\" content=\"text/html;charset=utf-8\">\n<TITLE>302 Moved</TITLE></HEAD><BODY>\n<H1>302 Moved</H1>\nThe document has moved\n<A HREF=\"http://www.google.co.in/?gfe_rd=cr&ei=DBAaWbWTLurx8AeKp4uwCg\">here</A>.\r\n</BODY></HTML>\r\n",
headers: %HTTPotion.Headers{hdrs: %{"cache-control" => "private",
"content-length" => "261", "content-type" => "text/html; charset=UTF-8",
"date" => "Mon, 15 May 2017 20:31:08 GMT",
"location" => "http://www.google.co.in/?gfe_rd=cr&ei=DBAaWbWTLurx8AeKp4uwCg",
"referrer-policy" => "no-referrer"}}, status_code: 302}
Installation
mix escript.install hex mix_script
This will install the binary into your $HOME/.mix/escripts directory, so make sure that is part of your $PATH
TODO
- Make this more efficient by using a common directory for the mix packages
- Make it usable via a shebang
#!/usr/bin/env mix_scriptwhich does compilation and execution
