erlang support: seperate hex and rebar3 support Building Hex packages is a superset of building with rebar3. There is no need to force folks that use rebar3 but not hex to build with hex. This commit seperates the rebar3 specific bits and the hex specific bits into seperate functions that can be used independently. 2016-01-11 02:25:45 +03:00			`{ stdenv, buildRebar3, fetchHex }:`

Add support for Hex package name There are some packages on Hex which have custom hex-specific names, but inside there's a base project name. Remove most packages andadd ibrowse, meck, jiffy 2015-12-10 23:39:13 +03:00			`, hexPkg ? name`

Add shell env to buildHex packages. This adds erlangPackages.${name}.env, which is usable to launch a shell with the package and it's dependencies like this: nix-shell -A erlangPackages.lager.env This required: 1) refactoring buildHex to become a fixed-point function, 2) moves output of a package into $out/${name}, 3) introduces erlEnv (buildEnv, which links in package and it's deps into one directory - a super-simple plagiarization of haskellPackages.compiler.ghcWithPackages) and 4) shell function producing a un-buildable derivation to be used by nix-shell 2015-12-19 01:51:51 +03:00			`let`
