Dependents Tree

Writes a list of local apps to "stdio" after ordering them topologically.

These local apps should be under some projects directory and environment variable PROJEX_DIR should be set to it.

Only projects containing file deps_tree.dot (created by mix deps.tree --format dot) will be considered. Each project's root directory must match its underlying app name. For instance, directory dependents_tree for app :dependents_tree. Does not support umbrella projects.

The dependencies of an app are specified in the mix.exs file. The dependents of an app are those apps using it as a dependency.

Allows to update local interdependent apps in a topological order. In other words, if a given app is changed, what other apps become outdated (directly or indirectly) and in what order should they be updated so that, at the end, they are all up-to-date.

Usage

To use Dependents Tree locally, run these commands:

• set PROJEX_DIR=<elixir_projects_dir>
• git clone https://github.com/RaymondLoranger/dependents_tree
• cd dependents_tree
• mix deps.get
• mix escript.build
• mix escript.install

You can now run the application like so:

• deps_tree --help
• deps_tree --all
• deps_tree <app_dir>
