General infos about spack

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 v0.20.1.5 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
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>`
