ExProjections

Elixir's umbrella structure doesn't work out-of-the-box with vim-projectionist. The problem is that vim-projectionist allows one wildcard expression in the path, and umbrella apps require two.

The workaround is to put a custom-generated file .projections.json into the root directory of your elixir project. This will provide quick navigation between source files and their corresponding tests, even for umbrella projects.

This library simply writes a custom .projections.json file to your local directory.

The .projections.json file will be read by vim-projectionist, and also by the projectionist plugins for vscode, atom and probably other editors.

Use as an Escript

First, clone the repo locally:

git clone https://github.com/andyl/ex_projections

Then install the escript:

cd ex_projections
mix deps.get
mix compile
mix escript.install --force
asdf reshim elixir           # if using asdf...

Once installed, you can run the escript:

cd <yourproject>
ex_projections

Use as a Mix Task

The package can be installed by adding ex_projections to your list of dependencies in mix.exs:

def deps do
  [
    {:ex_projections, git: "https://github.com/andyl/ex_projections"}
  ]
end

Once this is done, you can run the mix task:

mix ex_projections
