Updates rebar3 to version 3.6.1, which amongst other things introduces
support for rebar3 on Erlang/OTP 21.
Changes made:
* rebar3 and dependencies updated to new versions
* rebar3 hermeticity patch updated to apply against new version
* hex package registry snapshot updated
* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
The documentation got a bit stale compared to actual contents of
nixpkgs. This commit focuses on updating existing docs, not on making
sure all details of beam packages are covered.
This allows you to turn on debug infor for all the beam packages in the
system with a single change at the top level. This is required for
debugging and dialyzer work. It also allows you to switch it on on a
package by package basis.
This adds changes to the rebar3 expression that patch rebar3 to force it
to be hermetic. Now, by default, rebar3 literally can't download
anything. A 'rebar3-open' expression was added for those folks whe want
the normal rebar3.
To successfully build rebar packages, it needs to be provided with
rebar3 plugins used to build it. This change passes them to env
variable. From there rebar3-nix-bootstrap takes them and symlinks into
_build/default/plugins.
