When compiling on FreeBSD, use gmake instead of make.

The compile_dir functionality was broken (again).
This test case was very much over due..

As `rebar eunit` doesn't compile .yrl files,
we need to make sure those are already compiled
when running the eunit tests.

The backward incompatible change introduced in commit
0b61b69 is reverted, and instead a
new `render` function is added for those who wish to get the tagged
result tuple `{ok, iolist()} | {error, Reason}`.

Old API still available: new api's responses are converted to
old ones.
There is phrase information fields added, which we currently don't
extract, like 'msgid_plural', 'context'. Will be implemented later.

Also make sure that the needed source files are present
when running the test suite.

Dependencies are not pinned down, but follow their
respective development branches.

Our version is generated on build time using git
(e.g. it requires a git cloned repository to build).

The NEWS files is flushed, so it only contains the
bullets of news since the last release merge.

Conflicts:
	NEWS.md
	rebar.config
	src/erlydtl.app.src

Resolved conflicts to keep master a development branch, with a clean
NEWS file, while the stable branch has the full NEWS history and
pinned dependencies and a hard coded version in the .app.src file.

As the NEWS items are merged with stable and released,
they are dropped from the master branch to keep it
clean and tidy around here..

this makes the code so much more readable, and easier to tweak.

vars is deprecated (aliased to default_vars).

The `forloop` variable is now marked as a reserved internal variable name,
and can't be used default/constant variable.

it is no longer used.

merl depends on changes in erl_syntax introduced in R15B02: erlang/otp@5374607

Avoid always running the merl tests when only compiling.

cf. richcarl/merl#6

call the {# .. #}-construct for comment tag (previously comment_inline).
n.b. {% comment %} ... {% endcomment %} is a comment block.

some cleanups in sources_parser + handle the new comment_tag token.

beginnings of tests for the unparser (currently lives in the sources parser test suite).

open question: we ought to support multiple plural tags
  to support languages that have more than two variations
  dependent on the count.

Support trans_fun/1 as compile time translation fun too..

Print warning message to stderr on unclosed variable in block translation.

Completely backwards compatible, but means we can enable
warnings_as_errors, and name unused variables with an underscore.
(see 2 new tests)

Merge branch 'master' into stable

Previously, we were checking if the directory exists, but not checking
it with respect to the doc_root exists.  Instead, we were ensuring the
directory with respect only to the originally provided "debug_root".

This patch ensures (har har) that when we are ensuring the directory for
debug purposes, that it includes the full path to the file.

*Additionally* calling filelib:ensure_dir(Dir) will only ensure the
directories up to the *parent* of Dir.  It's a little bit wonky, so
typically one would append a "dummy" file to a Dir path.  But we don't
need to do this since Abs is itself a file, so we ensure_dir(Abs), and
it'll ensure all the directories correctly.

Example: filelib:ensure_dir("/foo/bar/whatever/something"), will only
ensure that the directories "/foo/bar/whatever" exist and will create
them if necessary. "something" is not actually used.

The short of it is that this will fix debug_root if a doc_root is
specified, and the File to be compiled is specified with directories as
well, such as "src/view/whatever.html".

Fix ensure_dir when debug_root is specified

When base and parent templates within {%block%} tags contain for loops,
there is an 'unsafe L' error due to matched variables automatically
being bound in case expressions.  This wraps the case statement in a
function call, containing the 'L' variable, and preventing a crash.

This also adds the relavent test.

Now, the . for looking up an attribute of a variable will bypass any other reserved meaning that the
indentifier may normally hold. So, in a way, the attribute lookup opertaion short-circuits the
keyword mechanism. Which makes sense, as it won't make sense to put a keyword after the dot any way.

Added a note about why merl may fail to compile

fixes #176.

avoid duplicate entries in ast info.

add trace message on includes.

Ref. #176.

Merl is an application dependency

Don't run tests by default.

N.b. without auto_escape enabled, it works as expected.

…ces.

Fix quoting in pre_hooks to get it compiling when folder name has spaces...

Added optional list of filters to apply when looking up scoped
variables.

The `block.super` variable has the `safe` filter applied to it, to
avoid further escaping.
