Pesto - Bazel Dependency Manager

Pesto is a simple dependency manager for Bazel. In order to use Pesto, you'll need to add a bazel_spec.json file at the root of your workspace with the following contents:

{
  "name": "pesto_sample_project",
  "version": "0.0.1",
  "doc": "Sample project that uses Pesto for dependencies.",
  "bazel_compatible": "0.21.0",
  "deps": [<dependencies>]
}

In addition, you'll need to add the following at the top of your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

git_repository(
    name = "pesto",
    remote = "https://github.com/sergiocampama/pesto",
    tag = "0.0.1",
)

load("@pesto//:pesto.bzl", "pesto_setup")
pesto_setup()

load("@pesto_generated//:load.bzl", "pesto_load")
pesto_load()

load("@pesto_generated//:init.bzl", "pesto_init")
pesto_init()

This is all the setup required to start using Pesto.

Dependencies

Dependencies can be either remote Git repositories or local dependencies. To declare a remote dependency, add it like this:

{
  ...,
  "deps": [
    {
      "url": "https://github.com/remote/dependency",
      "from": "0.0.1"
    }
  ]
}

The url field points to a remote repository containing a Pesto enabled dependency. The from field specifies the version requested from that dependency. This version is resolved by means of Git tags. Tags are automatically created when creating a Release in Github, for example.

Local dependencies are declared using absolute paths:

{
  ...,
  "deps": [
    {
      "path": "/path/to/local/dependency"
    }
  ]
}

Local dependencies override any remote dependency. Local dependencies can only be declared in the root manifest file (i.e. the manifest file of the workspace where Bazel is being run). These are mostly used for development or debugging purposes.
