Get a fresh copy of the `abra` source code from [here](https://git.coopcloud.tech/coop-cloud/abra).
Install [direnv](https://direnv.net), run `cp .envrc.sample .envrc`, then run `direnv allow` in this directory. This will set coopcloud repos as private due to [this bug.](https://git.coopcloud.tech/coop-cloud/coopcloud.tech/issues/20#issuecomment-8201). Or you can run `go env -w GOPRIVATE=coopcloud.tech` but I'm not sure how persistent this is.
Install [Go >= 1.16](https://golang.org/doc/install) and then:
Our [Drone CI configuration](https://git.coopcloud.tech/coop-cloud/abra/src/branch/main/.drone.yml) runs a number of checks on each pushed commit. See the [Makefile](https://git.coopcloud.tech/coop-cloud/abra/src/branch/main/Makefile) for more handy targets.
Warning, there is currently no stability promise for the `abra` public API! Most of the internals are exposed in order to allow a free hand for developers to try build stuff. If people start to build things then we can start the discussion on what is useful to have open/closed and keep stable etc. Please let us know if you depend on the APIs!
The `pkg.go.dev` documentation is [here](https://pkg.go.dev/coopcloud.tech/abra). Here's a brief example to get you going:
If there's no official release for the architecture you use, you can cross-compile `abra` very easily. Clone the source code from [here](https://git.coopcloud.tech/coop-cloud/abra) and then:
- enter the `abra` directory
- run `git tag -l` to see the list of tags, choose the latest one
- run `git checkout <tag>`, where `<tag>` is the latest version
- run `GOOS=<os> GOARCH=<arch> [GOARM=<arm>] make build`. You only have to use `GOARM` if you're building for ARM, this specifies the ARM version (5,6,7 etc). See [this](https://go.dev/doc/install/source#environment) for a list of all supported OS'es and architectures.
We use [goreleaser](https://goreleaser.com) to help us automate releases. We use [semver](https://semver.org) for versioning all releases of the tool. While we are still in the public beta release phase, we will maintain a `0.y.z-beta` format. Change logs are generated from our commit logs. We are still working this out and aim to refine our release praxis as we go.
For developers, while using this `-beta` format, the `y` part is the "major" version part. So, if you make breaking changes, you increment that and _not_ the `x` part. So, if you're on `0.1.0-beta`, then you'd go to `0.1.1-beta` for a backwards compatible change and `0.2.0-beta` for a backwards incompatible change.
- Change `ABRA_VERSION` in [`scripts/installer/installer`](https://git.coopcloud.tech/coop-cloud/abra/src/branch/main/scripts/installer/installer) to match the new tag (use [semver](https://semver.org))
We maintain a fork of [godotenv](https://git.coopcloud.tech/coop-cloud/godotenv) because we need inline comment parsing for environment files. You can upgrade the version here by running `go get git.coopcloud.tech/coop-cloud/godotenv@0<COMMID>` where `<commit>` is the latest commit you want to pin to. See [`abra#391`](https://git.coopcloud.tech/coop-cloud/abra/pulls/391) for more.
A number of modules in [pkg/upstream](https://git.coopcloud.tech/coop-cloud/abra/src/branch/main/pkg/upstream) are copy/pasta'd from the upstream [docker/docker/client](https://pkg.go.dev/github.com/docker/docker/client). We had to do this because upstream are not exposing their API as public.
