Lock file proposal

Dependency Locking with the Swift Package Manager

Introduction

In a vibrant packaging ecosystem, dependencies update continuously with bug-fixes and feature improvements. When working against a collection of dependencies, especially in a team, it is vital to lock the graph and update it so that all team members receive the exact same graph at the same time.

The typical flow for this in dependency management is to create and use a dependency “Lockfile”.

RFC: Dependency Manager Install Location

Motivation

One of the core benefits of tea: it's relocatable. tea does not pollute your system environment, everything gets "installed" in a relocatable folder ~/.tea.

tea can also install languages like node and ruby and it's dependency managers, npm and gem, respectively. However, these language dependency managers install packages to global directories like ~/.npm and ~/.gem. Tools from these ecosystems expect to find packages in these locations.

In this RFC, we would love to hear feedback from the community.
