myriad

% This is a (manually crafted) configuration file of rebar3, so that
% Ceylan-Myriad can better integrate in the current OTP ecosystem, despite its
% (more complex) build based on GNU make.


% Base layout was obtained thanks to: 'rebar3 new lib myriad', as Myriad is a
% library OTP application (without supervision trees).

% To be run from the library root as 'rebar3 compile' or 'rebar3 release'.

% Settings for the 'default' profile follow.


% No dependency (except Erlang of course):
{deps, []}.


% We need to rely on our dedicated build procedure (ex: for the parse transforms
% involved):
%
% Could not set REBAR_PROFILE=$(REBAR_PROFILE):
%
%{pre_hooks, [ {compile, "make -s rebar3-info"} ]}.
{pre_hooks, [ {compile, "make -s rebar3-compile"} ]}.

%{post_hooks, [
%	{compile, "echo 'Myriad post-compile hook!'"} ]}.



% For release generation:
%
% (defaults are for the development mode)
%
{relx, [

  {release, {myriad_release, {cmd, "cat GNUmakevars.inc | grep 'MYRIAD_VERSION := '| sed 's|^MYRIAD_VERSION := ||1' | tr -d '\n'"}}, [sasl, myriad]},

  %{sys_config, "./config/sys.config"},
  %{vm_args, "./config/vm.args"},

  {dev_mode, true},
  {include_erts, false},

  {extended_start_script, true},
  {include_src, false}

]}.


{profiles, [

  % Production mode:
  {prod, [ {relx, [

	% Same as default profile:
	{release, {myriad_release, {cmd, "cat GNUmakevars.inc | grep 'MYRIAD_VERSION := '|sed 's|^MYRIAD_VERSION := ||1' | tr -d '\n'"}}, [sasl, myriad]},

	% For the build makefiles:
	{env, [ { 'REBAR_PROFILE', "prod" } ] },

	% Not wanting the release to contain symlinks to applications:
	{dev_mode, false},
