From 9d788d893620f868b9c0ee00ddec8ae4d5d8fea7 Mon Sep 17 00:00:00 2001 From: Fred Hebert Date: Fri, 5 Oct 2018 07:57:20 -0400 Subject: Abstracted path management Move path management out of rebar_utils manual code path function handling (which we leave there for backwards compat), and centralize them to allow easier coordination of paths between plugins and deps. On top of path handling, do a check of loaded modules to only purge and reload those that actually need it done in order to prevent all kinds of weird interaction and accidental purge kills. It also allows the possible cohabitation of both at once, with a "in case of conflict pick X" as a policy Changing path handling in providers also highlighted a bunch of bugs in some tests and appears to fix some in other providers, specifically around plugins. --- src/rebar_api.erl | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'src/rebar_api.erl') diff --git a/src/rebar_api.erl b/src/rebar_api.erl index 4dabe8a..00eb054 100644 --- a/src/rebar_api.erl +++ b/src/rebar_api.erl @@ -9,6 +9,8 @@ expand_env_variable/3, get_arch/0, wordsize/0, + set_paths/2, + unset_paths/2, add_deps_to_path/1, restore_code_path/1, processing_base_dir/1, @@ -67,6 +69,21 @@ get_arch() -> wordsize() -> rebar_utils:wordsize(). +%% @doc Set code paths.
