dagger install --export

Problem

In monorepos, it's common for each sub-project of the repo to have its own submodule. But there is no easy way for the root module to "pass through" the functions of its submodules to the user. For example:

• submodules frontend and backend are installed in the root module
• dagger call frontend build won't work: instead dagger call -m frontend build is required.
• dagger functions shows no functions

Solution

Allow specifying a dependency as exported. This passes through the dependency's types and functions to the parent's namespace.

Example:

1. Export some dependencies

dagger install --export ./cli
dagger install --export ./engine
dagger install --export ./sdk
dagger install --export ./docs

1. Inspect functions

$ dagger functions
cli
engine
sdk
docs

1. call a function

dagger call cli build -o ./bin/dagger
