Julia Package Management

Manage Julia packages in the current environment.

Arguments

• action - One of: add, rm, status, update, instantiate, resolve, test, develop, free
• packages - Package names or paths (required for add/rm/develop/free, optional for update/test)

Instructions

Parse the user's arguments to determine the action and packages:

User Input	Action	Packages
add JSON	add	JSON
add JSON DataFrames CSV	add	JSON, DataFrames, CSV
rm OldPackage	rm	OldPackage
status	status	(none)
update	update	(none - updates all)
update JSON	update	JSON
instantiate	instantiate	(none)
resolve	resolve	(none)
test	test	(none - tests current project)
test MyPackage	test	MyPackage
develop ./MyLocalPkg	develop	./MyLocalPkg
free MyPackage	free	MyPackage

Call pkg with the appropriate action and packages parameters.

Notes

• After adding packages, remind the user to load them with using PackageName
• The instantiate action installs dependencies from Project.toml/Manifest.toml
• The test action runs Pkg.test() - can be slow for large test suites
• The develop action puts a package in development mode (uses local code)
• The free action exits development mode (returns to registry version)
• After develop, consider using revise(action="revise") to hot-reload changes
