If the application's Makefile specify either:
DEP_PLUGINS = $(PROJECT)
or e.g.:
DEP_PLUGINS = $(PROJECT)/mk/dist.mk
then load the plugin from the application instead of a dependency.
This helps when you have an application with common Erlang modules and
Erlang.mk plugins: your common application can load Erlang.mk plugins
exactly like other applications depending on the common application.

We do not touch the erlang.mk file anymore. We only patch the
Makefile to include the top-level Erlang.mk by changing the
'include erlang.mk' line to look for ERLANG_MK_FILENAME if it
is defined. The modified Makefile can be committed safely.

Regular plugins (`$(DEP_PLUGINS)`) are loaded near the end of Erlang.mk.
This is fine when you want to modify variables initialized earlier in
Erlang.mk or add new targets and variables.
However, it doesn't allow you to declare more dependencies because they
are loaded too late for that.
This commit introduces a new variable, `$(DEP_EARLY_PLUGINS)`, which can
be used to list plugins meant to be loaded near the beginning of
Erlang.mk. Those allow to append to the list of dependencies.
They work exactly like regular plugins otherwise. The default filename
loaded is `early-plugins.mk`.

Before this change, the build would continue, even if a dependency
failed to build. This could lead to obscure errors in the middle of a
testsuite for instance.
With this change, the build fails immediately, exactly like when a
regular dependency fails to build.
While here, replace most uses of `|| exit $$?` with `set -e`. This
simplifies error handling if we need to add more commands to each
blocks.
Also, echo error messages to stderr.

This silences warnings such as:
mv: rename file.app to file.app.src: No such file or directory
They are harmless really, but still annoying.

we also use LOCAL_DEPS at the top-level, if it exists, to determine
which local apps to compile, in the interest of saving compile time
for projects that have many apps and multiple release configurations
|
|
`rm deps.log` was not being executed, because of 1) the ifeq around
it, checking for an empty ALL_DEPS_DIRS, which i believe was a logical
error; and 2) deps depended on apps, which means apps were compiled
before its recipe was executed, and the `rm deps.log` would be
executed after it had been written to by recursive make of the
apps.
the important reason to remove deps.log is so that dependencies get
remade when they change. otherwise you'll get mysterious errors about
missing dependencies if they need to be rebuilt, or worse, have wrong
stale beam files bundled in your release.
tests core-deps-apps and core-deps-apps-only now manually clean the
cowlib dep and rebuild at the top-level to make sure cowlib gets
rebuilt. both tests indeed fail without this fix.
this attempts to fix #1 by removing the ifeq, and #2 by having deps
and apps depend on deps.log, with deps.log 'built' (but actually
removed) by a double-colon rule with no prerequisites (which means its
recipe always be run).

This allows all plugins to append to existing variables
and makes it easier to augment the functionality of the
core plugins.
|

Erlang.mk projects either have a .app.src, or just the Makefile
with an optional .app file for compatibility.
|
|
If we have a .app and a .app.src we delete the .app.
If we have a Rebar project with a .app file, rename it to
.app.src and continue with autopatch.
If we have a non-Rebar project, leave the .app file, and then...
For all cases, delete the ebin/ folder after autopatch completes.

.. to fetch and list deps recurvively.
Therefore, they work on direct dependencies, dependencies' dependencies,
and so on. Nothing is built with those targets.
The following targets are also available to work on other kinds of
dependencies:
make fetch-doc-deps
make fetch-rel-deps
make fetch-test-deps
make fetch-shell-deps
make list-doc-deps
make list-rel-deps
make list-test-deps
make list-shell-deps
In all cases, they include "normal" and eg. "test" dependencies of the
top-level project, then only "normal" dependencies' dependencies.
It's possible to include several kinds in one go:
make fetch-deps DEP_TYPES='doc test'
make list-deps DEP_TYPES='doc test'
As it may be difficult to use the output of `make list-*` because
the list could appear after other targets output (like dependencies
fetching), the list is available in files pointed by the following
variables:
$(ERLANG_MK_RECURSIVE_DEPS_LIST)
$(ERLANG_MK_RECURSIVE_DOC_DEPS_LIST)
$(ERLANG_MK_RECURSIVE_REL_DEPS_LIST)
$(ERLANG_MK_RECURSIVE_TEST_DEPS_LIST)
$(ERLANG_MK_RECURSIVE_SHELL_DEPS_LIST)
Internally, `list-deps` is simply implemented on top of `fetch-deps`:
the latter fills a sorted log with all the directories it traversed.
`list-deps` finally just prints the log file to stdout.
Fixes #560.

This change makes it possible to override the ERL_CFLAGS and ERL_LDFLAGS
Makefile variables in project dependencies. For the main project, the
ability to override variables associated with C compilation already
existed in plugins/c_src.mk. With this change, the C compiler flag
semantics are similar for both the main project and dependencies.
This is important for cases where the automatically determined values
for the ERTS include and library directories are incorrect. This happens
in cross-compiled environments where they point to the host's include
and library directories. However, the desired behaviour is to have them
point to those that have been cross-compiled for the target.

One case was added, where a -compile attribute specified a list
that included a parse_transform. This affected alog, for example.
The COMPILE_FIRST variable is now filled from a digraph. This
allows us to keep track of the dependency tree properly, rather
than rely on luck. This affected erlando.
With both of these changes in, a large chunk of the rebar
autopatch code can be removed, the part that concerned the
auto detection of file dependencies.
On the other hand, we still need to honor the erl_first_files
configuration value, otherwise the parse_trans project fails
to build. While it would be possible to detect these dependencies
automatically too, it's probably too complex to bother, at least
for now.

This allows us to avoid autopatching when the Makefile of an
Erlang.mk project contains the word "rebar".
Had to update elvis and xref_runner to master for now because
of incompatibilities. The problem went unnoticed for a while
because they were autopatched.

... not the first.
dep_autopatch can be an expensive macro, in particular because it
executes Erlang. So if NO_AUTOPATCH is set, it's best to avoid calling
dep_autopatch as the result will be unused anyway.
While here, add a test for autopatched rebar-based dependencies.

The `-n` flag is not standard and not portable. It is supported by many
Bourne shell to suppress the trailing newline character. But some old
shells do not support this and "-n" is printed.
This is the case for instance on some old versions of Mac OS X where
`/bin/sh` is Bash 3.2.

Therefore, if neither $(dep_something) nor $(pkg_something_name) is
defined, $(dep_name) will return the name specified in the various
dependencies lists.
This fixes `core-app-pt-erlc-opts` and `core-deps-fetch-fail-unknown`
because now, the dependency is not "forgotten" anymore. Before,
the dependency directory was missing from $(ALL_DEPS_DIRS) because
$(dep_name) returned nothing.

This changes adds Rebar-like "apps/" functionality.
From this commit onward, Erlang.mk supports 4 types of repositories:
- Repo with an Erlang app at root level + deps/
- Repo with an Erlang app at root level + apps/ deps/
- Repo with no app at root level + deps/
- Repo with no app at root level + apps/ deps/
Example usage:
- make new-app in=webchat
- make new t=gen_server n=my_chat in=webchat
- make
Replace new-app with new-lib to create an OTP library instead of
an OTP application.

Fix IGNORE_DEPS handling with autopatched Rebar projects,
where the user defined value was overriden with the one
from autopatching.
