As we move towards extensible snapshots, we want to make sure we have the bare minimum of information to allow a shared data type for parsing all kinds of snapshots.

Most +old syntax is still supported with newer versions of Stack, but will +not be documented here. Instead, this section contains the recommended +syntax as of Stack v1.6.0. -The `packages` section lists all local (project) packages. The term _local -package_ should be differentiated from a _dependency package_. A local package -is something that you are developing as part of the project. Whereas a -dependency package is an external package that your project depends on. +There are two types of packages that can be defined in your +`stack.yaml` file: -In its simplest usage, it will be a list of directories or HTTP(S) URLs to a -tarball or a zip. For example: +* __Project packages__, those which you are actually working on in + your current project. These are local file paths in your project + directory. +* __Extra dependencies__, which are packages provided locally on top + of the snapshot definition of available packages. These can come + from Hackage (or an alternative package index you've defined, see + [package-indices](#package-indices)), an HTTP(S) tarball, a Git or + Mercurial repository, or a local file path. + +These two sets of packages are both installed into your local package database within your project. However, beyond that, they are completely different: + +* Project packages will be built by default with a `stack build` + without specific targets. Extra dependencies will only be built if + they are depended upon. +* Test suites and benchmarks may be run for project packages. They are + never run for extra dependencies. + +The `packages` key is a simple list of file paths, which will be +treated as relative to the directory containing your `stack.yaml` +file. For example: ```yaml packages: - - . - - dir1/dir2 - - https://example.com/foo/bar/baz-0.0.2.tar.gz +- . +- dir1/dir2 ``` -Each package directory or location specified must have a valid cabal file -present. Note that the subdirectories of the directory are not searched for -cabal files. Subdirectories will have to be specified as independent items in -the list of packages. +Each package directory or location specified must have a valid cabal +file or hpack `package.yaml` file present. Note that the +subdirectories of the directory are not searched for cabal +files. Subdirectories will have to be specified as independent items +in the list of packages. When the `packages` field is not present, it defaults to looking for a package in the project's root directory: ```yaml packages: - - . +- . ``` -#### Complex package locations (`location`) -More complex package locations can be specified in a key-value format with -`location` as a mandatory key. In addition to `location` some optional -key-value pairs can be specified to include specific subdirectories or to -specify package attributes as descibed later in this section. +The `extra-deps` key is given a list of all extra dependencies. If +omitted, it is taken as the empty list, e.g.: -In its simplest form a `location` key can have a single value in the same way -as described above for single value items. Alternativel it can have key-value -pairs as subfields to describe a git or mercurial repository location. For -example: +```yaml +extra-deps: [] +``` + +It supports four different styles of values: + +#### Package index + +Packages can be stated by a name/version combination, which will be +looked up in the package index (by default, Hackage). The basic syntax +for this is: ```yaml -packages: -- location: . -- location: dir1/dir2 -- location: https://example.com/foo/bar/baz-0.0.2.tar.gz -- location: http://github.com/yesodweb/wai/archive/2f8a8e1b771829f4a8a77c0111352ce45a14c30f.zip -- location: - git: git@github.com:commercialhaskell/stack.git - commit: 6a86ee32e5b869a877151f74064572225e1a0398 -- location: - hg: https://example.com/hg/repo - commit: da39a3ee5e6b4b0d3255bfef95601890afd80709 +extra-deps: +- acme-missiles-0.3 ``` -Note: it is highly recommended that you only use SHA1 values for a Git or -Mercurial commit. Other values may work, but they are not officially supported, -and may result in unexpected behavior (namely, stack will not automatically -pull to update to new versions). +Using this syntax, the most recent Cabal file revision available will +be used. For more reproducibility of builds, it is recommended to +state the SHA256 hash of the cabal file contents as well, like this: -A `location` key can be accompanied by a `subdirs` key to look for cabal files -in a list of subdirectories as well in addition to the top level directory. +```yaml +extra-deps: +- acme-missiles-0.3@sha256:2ba66a092a32593880a87fb00f3213762d7bca65a687d45965778deb8694c5d1 +``` + +__NOTE__ Future versions of Stack may support specifying revisions by +the revision number, providing more convenient than a hash with +slightly less guarantees of reproducibility. + +#### Local file path -This could be useful for mega-repos like -[wai](https://github.com/yesodweb/wai/) or -[digestive-functors](https://github.com/jaspervdj/digestive-functors). +Like `packages`, local file paths can be used in `extra-deps`, and +will be relative to the directory containing the `stack.yaml` file. -The `subdirs` key can have multiple nested series items specifying a list of -subdirectories. For example: ```yaml -packages: -- location: . - subdirs: - - subdir1 - - subdir2 -- location: - git: git@github.com:yesodweb/wai - commit: 2f8a8e1b771829f4a8a77c0111352ce45a14c30f - subdirs: - - auto-update - - wai -- location: http://github.com/yesodweb/wai/archive/2f8a8e1b771829f4a8a77c0111352ce45a14c30f.zip - subdirs: - - auto-update - - wai +extra-deps: +- vendor/somelib ``` -#### Local dependency packages (`extra-dep`) -A `location` key can be accompanied by an `extra-dep` key. When the -`extra-dep` key is set to `true` it indicates that the package should be -treated in the same way as a dependency package and not as part of the project. -This means the following: -* A _dependency package_ is built only if a user package or its dependencies - depend on it. Note that a regular _project package_ is built anyway even if - no other package depends on it. -* Its test suites and benchmarks will not be run. -* It will not be directly loaded in ghci when `stack ghci` is run. This is - important because if you specify huge dependencies as project packages then - ghci will have a nightmare loading everything. +Note that if a local directory can be parsed as a package identifier, +Stack will treat it as a package identifier. In other words, if you +have a local directory named `foo-1.2.3`, instead of: + +```yaml +extra-deps: +- foo-1.2.3 +``` -This is especially useful when you are tweaking upstream packages or want to -use latest versions of the upstream packages which are not yet on Hackage or -Stackage. +You should use the following to be explicit: -For example: ```yaml -packages: -- location: . -- location: vendor/binary - extra-dep: true -- location: - git: git@github.com:yesodweb/wai - commit: 2f8a8e1b771829f4a8a77c0111352ce45a14c30f - subdirs: - - auto-update - - wai - extra-dep: true +extra-deps: +- ./foo-1.2.3 ``` -### extra-deps +#### HTTP(S) URLs -This is a list of package identifiers for additional packages from upstream to -be included. This is usually used to augment an LTS Haskell or Stackage Nightly -snapshot with a package that is not present or is at an different version than you -wish to use. +This one's pretty straightforward: you can use HTTP and HTTPS URLs +referring to either tarballs or ZIP files. + +__NOTE__ Stack assumes that these files never change after downloading +to avoid needing to make an HTTP request on each build. ```yaml extra-deps: -- acme-missiles-0.3 +- location: https://example.com/foo/bar/baz-0.0.2.tar.gz +- location: http://github.com/yesodweb/wai/archive/2f8a8e1b771829f4a8a77c0111352ce45a14c30f.zip ``` -Note that the `extra-dep` attribute in the `packages` section as described in -an earlier section is used for non-index local or remote packages while the -`extra-deps` section is for packages to be automatically pulled from an index -like Hackage. +#### Git and Mercurial repos -### resolver +You can give a Git or Mercurial repo at a specific commit, and Stack +will clone that repo. + +```yaml +extra-deps: +- git: git@github.com:commercialhaskell/stack.git + commit: 6a86ee32e5b869a877151f74064572225e1a0398 +- hg: https://example.com/hg/repo + commit: da39a3ee5e6b4b0d3255bfef95601890afd80709 +``` -Specifies how dependencies are resolved.
