A project will typically also have a project file and +may optionally have a manifest file: + +- **Project file:** a file in the root directory of a project, named + `Project.toml` (or `JuliaProject.toml`), describing metadata about the project, + including its name, UUID (for packages), authors, license, and the names and + UUIDs of packages and libraries that it depends on. + +- **Manifest file:** a file in the root directory of a project, named + `Manifest.toml` (or `JuliaManifest.toml`), describing a complete dependency graph + and exact versions of each package and library used by a project. + +**Package:** a project which provides reusable functionality that can be used by +other Julia projects via `import X` or `using X`. A package should have a +project file with a `uuid` entry giving its package UUID. This UUID is used to +identify the package in projects that depend on it. + +!!! note + For legacy reasons it is possible to load a package without a project file or + UUID from the REPL or the top-level of a script. It is not possible, however, + to load a package without a project file or UUID from a project with them. Once + you've loaded from a project file, everything needs a project file and UUID. + +**Application:** a project which provides standalone functionality not intended +to be reused by other Julia projects. For example a web application or a +commmand-line utility, or simulation/analytics code accompanying a scientific paper. +An application may have a UUID but does not need one. +An application may also provide global configuration options for packages it +depends on. Packages, on the other hand, may not provide global configuration +since that could conflict with the configuration of the main application. + +!!! note + **Projects _vs._ Packages _vs._ Applications:** + + 1. **Project** is an umbrella term: packages and applications are kinds of projects. + 2. **Packages** should have UUIDs, applications can have a UUIDs but don't need them. + 3. **Applications** can provide global configuration, whereas packages cannot. + +**Library (future work):** a compiled binary dependency (not written in Julia) +packaged to be used by a Julia project. These are currently typically built in- +place by a `deps/build.jl` script in a project’s source tree, but in the future +we plan to make libraries first-class entities directly installed and upgraded +by the package manager. + +**Environment:** the combination of the top-level name map provided by a project +file combined with the dependency graph and map from packages to their entry points +provided by a manifest file. For more detail see the manual section on code loading. + +- **Explicit environment:** an environment in the form of an explicit project + file and an optional corresponding manifest file together in a directory. If the + manifest file is absent then the implied dependency graph and location maps are + empty. + +- **Implicit environment:** an environment provided as a directory (without a + project file or manifest file) containing packages with entry points of the form + `X.jl`, `X.jl/src/X.jl` or `X/src/X.jl`. The top-level name map is implied by + these entry points. The dependency graph is implied by the existence of project + files inside of these package directories, e.g. `X.jl/Project.toml` or + `X/Project.toml`. The dependencies of the `X` package are the dependencies in + the corresponding project file if there is one. The location map is implied by + the entry points themselves. + +**Registry:** a source tree with a standard layout recording metadata about a +registered set of packages, the tagged versions of them which are available, and +which versions of packages are compatible or incompatible with each other. A +registry is indexed by package name and UUID, and has a directory for each +registered package providing the following metadata about it: + +- name – e.g. `DataFrames` +- UUID – e.g. `a93c6f00-e57d-5684-b7b6-d8193f3e46c0` +- authors – e.g. `Jane Q. Developer <jane@example.com>` +- license – e.g. MIT, BSD3, or GPLv2 +- repository – e.g. `https://github.com/JuliaData/DataFrames.jl.git` +- description – a block of text summarizing the functionality of a package +- keywords – e.g. `data`, `tabular`, `analysis`, `statistics` +- versions – a list of all registered version tags + +For each registered version of a package, the following information is provided: + +- its semantic version number – e.g. `v1.2.3` +- its git tree SHA-1 hash – e.g. `7ffb18ea3245ef98e368b02b81e8a86543a11103` +- a map from names to UUIDs of dependencies +- which versions of other packages it is compatible/incompatible with + +Dependencies and compatibility are stored in a compressed but human-readable +format using ranges of package versions. + +**Depot:** a directory on a system where various package-related resources live, +including: + +- `environments`: shared named environments (e.g. `v1.0`, `devtools`) +- `clones`: bare clones of package repositories +- `compiled`: cached compiled package images (`.ji` files) +- `config`: global configuration files (e.g. `startup.jl`) +- `dev`: default directory for package development +- `logs`: log files (e.g. `manifest_usage.toml`, `repl_history.jl`) +- `packages`: installed package versions +- `registries`: clones of registries (e.g. `General`) + +**Load path:** a stack of environments where package identities, their +dependencies, and entry-points are searched for. The load path is controlled in +Julia by the `LOAD_PATH` global variable which is populated at startup based on +the value of the `JULIA_LOAD_PATH` environment variable. The first entry is your +primary environment, often the current project, while later entries provide +additional packages one may want to use from the REPL or top-level scripts. + +**Depot path:** a stack of depot locations where the package manager, as well as +Julia's code loading mechanisms, look for registries, installed packages, named +environments, repo clones, cached compiled package images, and configuration +files. The depot path is controlled by the Julia `DEPOT_PATH` global variable +which is populated at startup based on the value of the `JULIA_DEPOT_PATH` +environment variable. The first entry is the “user depot” and should be writable +by and owned by the current user. The user depot is where: registries are +cloned, new package versions are installed, named environments are created and +updated, package repos are cloned, newly compiled package image files are saved, +log files are written, development packages are checked out by default, and +global configuration data is saved. Later entries in the depot path are treated +as read-only and are appropriate for registries, packages, etc. installed and +managed by system administrators. |
