# Dependents Tree
Writes local apps to "stdio" after ordering them topologically.
Change management app topologically listing local apps residing
in a project directory set by environment variable `PROJEX_DIR`.
Only projects containing file `deps_tree.dot` will be considered.
To generate the DOT graph file, run `mix deps.tree --format dot`.
Each project's root directory must match the app name it contains.
For instance, dir `dependents_tree` for app `:dependents_tree`.
Does not support umbrella projects.
Allows to update local interdependent apps in a topological order.
In other words, if a given app changes, what other dependent apps
become outdated and in what order must they be updated themselves.
## Usage
To use `Dependents Tree` locally, run these commands:
- `set PROJEX_DIR="<elixir_project_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 <some_app>`
