Installed commands can be checked at runtime using require_cmd:
#!/usr/bin/env powscript
require_cmd 'echo'
echo 'hello world'
Remote packages can be included using aap, which is npm for bash+git. Assume this powscript:
#!/usr/bin/env powscript
require 'username/powscriptrepo/foo.pow'
echo 'hello world'
This can be installed by simply running aap install in the projectdirectory (which contains an aap.json).
Create aap.json like this:
$ wget "https://github.com/coderofsalvation/aap/raw/master/aap" -O ~/bin/aap && chmod 755 ~/bin/aap
$ git init
$ aap init
$ aap install ssh+git://user@github.com/username/powscriptrepo.git --save
$ git add aap.json && git commit -m "added remote dependencies" && git push origin master
once you pushed your repo to github, other users can simply run:
$ aap install
installing 'user@github.com/username/powscriptrepo.git'
├─ $ git clone ssh+git://user@github.com/username/powscriptrepo.git
