![]() * Methods setting the environment now do it separately for build and run Before this commit the `*_environment` methods were setting modifications to both the build-time and run-time environment simultaneously. This might cause issues as the two environments inherently rely on different preconditions: 1. The build-time environment is set before building a package, thus the package prefix doesn't exist and can't be inspected 2. The run-time environment instead is set assuming the target package has been already installed Here we split each of these functions into two: one setting the build-time environment, one the run-time. We also adopt a fallback strategy that inspects for old methods and executes them as before, but prints a deprecation warning to tty. This permits to port packages to use the new methods in a distributed way, rather than having to modify all the packages at once. * Added a test that fails if any package uses the old API Marked the test xfail for now as we have a lot of packages in that state. * Added a test to check that a package modified by a PR is up to date This test can be used any time we deprecate a method call to ensure that during the first modification of the package we update also the deprecated calls. * Updated documentation |

Spack
Spack is a multi-platform package manager that builds and installs multiple versions and configurations of software. It works on Linux, macOS, and many supercomputers. Spack is non-destructive: installing a new version of a package does not break existing installations, so many configurations of the same package can coexist.
Spack offers a simple "spec" syntax that allows users to specify versions and configuration options. Package files are written in pure Python, and specs allow package authors to write a single script for many different builds of the same package. With Spack, you can build your software all the ways you want to.
See the Feature Overview for examples and highlights.
To install spack and your first package, make sure you have Python. Then:
$ git clone https://github.com/spack/spack.git
$ cd spack/bin
$ ./spack install zlib
Documentation
Full documentation is available, or
run spack help
or spack help --all
.
Tutorial
We maintain a hands-on tutorial. It covers basic to advanced usage, packaging, developer features, and large HPC deployments. You can do all of the exercises on your own laptop using a Docker container.
Feel free to use these materials to teach users at your organization about Spack.
Community
Spack is an open source project. Questions, discussion, and contributions are welcome. Contributions can be anything from new packages to bugfixes, documentation, or even new core features.

Contributing
Contributing to Spack is relatively easy. Just send us a
pull request.
When you send your request, make develop
the destination branch on the
Spack repository.
Your PR must pass Spack's unit tests and documentation tests, and must be PEP 8 compliant. We enforce these guidelines with Travis CI. To run these tests locally, and for helpful tips on git, see our Contribution Guide.
Spack uses a rough approximation of the
Git Flow
branching model. The develop
branch contains the latest
contributions, and master
is always tagged and points to the latest
stable release.
