This change makes it possible to assign pre/post scripts to all
rebar commands. This allows users fine grained control over
when scripts and/or shell commands should be executed, where such
extensions are absolutely needed.
Several examples have been added to the rebar.config.sample file.
This commit changes how rebar determines which apps have been
updated, added and removed from a release during appup generation.
Rather than use app files it now determines this from the rel file
in each version of the release. In addition it fixes a bug reported
on the mailing list when generating appups when an application has
been added or removed from either release.
Rebar will exit with {error,bad_directory} when trying to restore the code
path after it has finished working on a subdirectory if there are invalid
relative paths in it. The problem was seen when executing the last line of
rebar_erlc_compiler:doterl_compile/3 (true = code:set_path(CurrPath)).
This change adds support for executing ct test runs based on test
specificiations, which was missing previously. The rebar_ct module
now looks for any number of files with a name ending in `test.spec`
and if it finds one or more, passes these after the `-spec` argument
to ct_run instead of explicitly configuring the config, user config
and coverage config variables.
When no specifications are found, then the module behaves as it did
before this change, and both the ct1 and (new) ct2 integration tests
appear to show this is a backwards compatible patch.
To further support OTP releases I have added support for generating
application appup files. These include instructions that systools uses
to generate a relup file which contains the low level instructions
needed to perform a hot code upgrade. My goal with this module is to
produce "good enough" appup files or at least a skeleton to help one get
started with something more complex. If an appup file already exists for
an application this command will not attempt to create a new one.
Usage:
$ rebar generate-appups previous_release=/path/to/old/version
Generally this command will be run just before 'generate-upgrade'.
If an app uses -include_lib for its own included files, compilation
fails if the app directory isn't in $ERL_LIBS because code:lib_dir/1
will return an error. An absolute path needs to be added to code path
instead of just "ebin".
In git origin/HEAD is a pointer to the default branch. This patch
allows two alternatives to explicitly specifying "HEAD" in git VC specs.
The first is a 2 arity form {git, Url} and the second is {git, Url, ""}
which worked in pre-update-deps rebars.
To support OTP release upgrades I have added support for building
upgrade packages. Support for this is included in the
rebar_upgrade module, specifically generate_upgrade/2. It requires
one variable to be set on the command line 'previous_release' which
is the absolute path or relative path from 'rel/' to the previous
release one is upgrading from. Running an upgrade will create the
needed files, including a relup and result in a tarball containing
the upgrade being written to 'rel/'. When done it cleans up the
temporary files systools created.
Usage:
$ rebar generate-upgrade previous_release=/path/to/old/version
This also includes a dummy application that can be used to test
upgrades as well as an example.
Special thanks to Daniel Reverri, Jesper Louis Andersen and
Richard Jones for comments and patches.
This change makes it possible to type the beginning (the prefix) of a
command name and rebar will guess the full name of the command,
thereby saving the user precious keystrokes. As long as the prefix
matches only one command, rebar runs that command, otherwise rebar
prints a list of candidate command names. The "-" character is
considered to be a word separator and the prefix matching is done per
word.
Example prefix matches:
co ==> compile
cl ==> clean
create ==> create
create-a ==> create-app
c-a ==> create-app
c-app ==> create-app
On one project I have a need to specify port_sources on R14 only
and on another different project port_sources for Darwin and Linux.
To this end add support to handle tuples of the form
{ArchRegex, PortSource} in the port_sources list, eg:
{port_sources, [{"R14", ["c_src/*.c"]}]}.
This patch remedies an issue where the ebin directory would be
erroneously created as a file by the first "mv" command in
rebar_protobuffs_compile.erl [line 106] if the ebin file did not
exist at the root application level.
In essence, the patch ensures that the ebin directory exists at
the application directory level before any "mv" commands are
executed. The following code was inserted at line 106:
ok = filelib:ensure_dir(filename:join("ebin","dummy")),
abnfc is an ABNF parser generator.
Options are:
- doc_root (defaults to "src")
- out_dir (defaults to "src")
- source_ext (defaults to ".abnf")
- module_ext (defaults to "")
Add support for defining template variables of the following form:
{variables, [{appid, "mochiwebapp"},
{author, "Mochi Media <dev@mochimedia.com>"},
{year, "2010"},
{version, "0.1"},
{port, 8080},
{dest, "{{appid}}"}]}.
Where dest may be overridden on the commandline but will default to
being the appid. Mochiweb uses this so that we can create new
projects from the template in a configurable directory.
So
$ rebar create template=mochiwebapp dest=foo appid=bar
I thought about special casing dest but figured it might be generally
useful to be able to nest template vars.
However this patch only does one level of resolution. So if
{variables, [{foo, "{{bar}}"},
{bar, "{{foo}}"}]}.
then bar will end up being the literal string {{bar}} and foo the
literal string {{foo}}.

Using rebar's commandline, enable/disable 'debug_info' for
compilation. This feature if added to all rebar compilers could help
simplify and standardize this common use case for all rebar build
targets.
Modify rm_rf and cp_r to work when {win32,_} = os:type().
Simplify rm_rf to only accept one filename, directoryname or wildcard.
Add unit tests to ensure a similar behaviour on windows and unix.
Thanks to tuncer for guidance and feedback.
The eunit_dir() does use the ?EUNIT_DIR macro internally, but it also builds, what I guess is, an absolute path, which might be better :) At least it's more consistent.
Normally the ebin directory doesn't contain any source files. Therefore it won't be kept in the repository by, at least, mercurial and also maybe git unless you put some .keep file in it or do some other hack. The ebin directory is created by rebar compile, but if rebar eunit is called before rebar compile, you end up with a {'EXIT', {{badmatch,{error,bad_directory}},...}. Another approach would be not to match cod:add_pathz(ebin_dir()) with ok, but I think this is an ok solution as well.
