Project directory structure

The directory structure of an Acton project follows a certain convention.

.
├── Acton.toml
├── build.sh
├── out
│   ├── dev
│   │   ├── bin
│   │   │   └── foo
│   │   └── lib
│   │       ├── foo.o
│   │       └── libActonProject.a
│   ├── rel
│   │   ├── bin
│   │   │   └── foo
│   │   └── lib
│   │       ├── foo.o
│   │       └── libActonProject.a
│   └── types
│       ├── foo.c
│       ├── foo.h
│       ├── foo.root.c
│       └── foo.ty
├── README.org
└── src
    └── foo.act

An Acton.toml file must be present in the project root, otherwise it is not considered a project.

src/ is used for all source files of the project. Use subdirectories to create hierarchies of modules, for example src/a/b.act is imported in an Acton program as import a.b.

Output goes into out/. A project archive file (libActonProject.a) contains the compiled output of all modules, but is considered an internal implementation detail. Don't touch it.

Executable binaries go in out/bin. The name of the binary is the name of the module which contains the specified root actor. In the example above, the root actor is foo.main, i.e. actor main in the module foo and consequently, the executable name is foo.
