This PR improves the validation of `modules.yaml` by introducing a custom validator that checks if an attribute listed in `properties` or `patternProperties` is a valid spec. This new check applied to the test case in #9857 gives: ```console $ spack install szip ==> Error: /home/mculpo/.spack/linux/modules.yaml:5: "^python@2.7@" is an invalid spec [Invalid version specifier] ``` Details: * Moved the set-up of a custom validator class to spack.schema * In Spack we use `jsonschema` to validate configuration files against a schema. We also need custom validators to enforce writing default values within "properties" or "patternProperties" attributes. * Currently, validators were customized at the place of use and with the recent introduction of environments that meant we were setting-up and using 2 different validator classes in two different modules. * This commit moves the set-up of a custom validator class in the `spack.schema` module and refactors the code in `spack.config` and `spack.environments` to use it. * Added a custom validator to check if an attribute is a valid spec * Added a custom validator that can be used on objects, which yields an error if the attribute is not a valid spec. * Updated the schema for modules.yaml * Updated modules.yaml to fix a few inconsistencies: - a few attributes were not tested properly using 'anyOf' - suffixes has been updated to also check that the attribute is a spec - hierarchical_scheme has been updated to hierarchy * Removed $ref from every schema * $ref is not composable or particularly legible * Use python dicts and regular old variables instead. |

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 libelf
