Workflow

With spack v0.18 we suggest local/individual spack instances and the use of spack environments.

A user clones the spack repo

git clone --depth 1 --recurse-submodules --shallow-submodules -b v0.18.1.10 https://github.com/C2SM/spack-c2sm.git

gets spack in the command line

. spack-c2sm/setup-env.sh

activates an environment

spack env activate <path_to_env>

and starts exploring

spack info <package>
spack spec <spec>

and building

spack install <spec>
spack dev-build <spec>

a package.

Updating spack-c2sm is in the hands of the user.

git pull
git submodule update --recursive

After an update we advice to clean

spack uninstall -a
spack clean -a
rm -rf ~/.spack

and rebuild.

Command cheat sheet

	Command
Clone	git clone --depth 1 --recurse-submodules --shallow-submodules -b <branch/tag> https://github.com/C2SM/spack-c2sm.git
Load	. spack-c2sm/setup-env.sh autodetects machine or . spack-c2sm/setup-env.sh <machine> forces machine or . spack-c2sm/setup-env.sh unknown uses blank config spack compiler find autodetects compilers spack external find --all autodetects externally installed packages
Update	git pull git submodule update --recursive
Clean	spack uninstall -a uninstalls all packages spack clean -a cleans all misc caches rm -rf ~/.spack removes user scope data

Spec syntax: <package>@<version>%<compiler>+<variant> ~<variant>^<sub-package> +<sub-package-variant><compiler flags>

	Command
Find	spack find lists all installed packages. spack find <spec> lists all installed packages that match the spec.
Info	spack info <package>
Spec	spack spec <spec> concretizes abstract spec (unspecfied variant = any) Spack is not required to use the default of an unspecified variant. The default value is only a tiebreaker for the concretizer.
Install	spack install <spec>
Locate	spack location --install-dir <spec> prints location of all installs that satisfy the spec
Load env	spack load <spec> loads run environment
Activate env	spack env activate <env_name>
Deactivate env	spack deactivate
