Sebex

The ultimate assistant in Membrane Framework releasing & development.

Installation

Sebex is a Python application and is officially supported on Linux and macOS systems. At least Python 3.8 is required. There is also Elixir analysis code, which is written in Elixir itself and distributed as an escript. For this to work, a reasonably fresh Erlang installation is also needed.

Currently, building and installation directly from source code is the recommended way, and the whole procedure is scripted using a makefile:

git clone https://github.com/membraneframework/sebex.git
cd sebex
make install

Under the hood this will build Elixir analyzer script and place it in the expected place, then it will install sebex package issuing pip install --user . command.

To update your existing installation, invoke make install again.

Usage

Setup communication with GitHub API

Make sure the repositories of your GitHub Organization are public. To allow Sebex to edit your repositories:

• Generate a GitHub Personal Access Token and set it as your SEBEX_GITHUB_ACCESS_TOKEN environment variable or pass it with the --github_access_token option.
• Generate SSH key, add it to the ssh-agent and add to your GitHub account.

Preparation

It's advisable to use the --workspace and --profile options when running Sebex or to set the corresponding env vars: SEBEX_WORKSPACE and SEBEX_PROFILE.

• The workspace is a directory, where sebex clones repositories, so that it can work on them later on. It also contains .sebex subdirectory, with some metadata files needed for sebex to run properly. The default workspace (applicable to a situation in which you haven't explicitly specified the workspace) is the directory, from which you are running the sebex.
• The profile helps you manage different sebex configurations. Each profile is described by the <profile name>.txt text file inside the <workspace_directory>/.sebex/profiles/ directory. You need to create that file on your own. An exemplary profile description file can be found inside examples/ subdirectory of this repository. Note, that the <profile name>.txt file has a .txt extension - later on, you will be able to refer to it with --profile <profile name> option within the command syntax.

To add an organization run:

sebex bootstrap -o <Github organization name>

This will create the manifest.yaml inside the .sebex subdirectory of your workspace directory. The manifest will contain a list of all public repositories in that organization. To exclude broken or unsupported repositories from further analysis add a new line containing !<project name> to your <workspace directory>/.sebex/profiles/<your profile>.txt file.

To perform further work Sebex must clone your organization's repositories to your local workspace:

sebex sync

You can view the dependency graph of your projects:

sebex graph --view

Releasing packages

Prepare a release plan by listing the project names (names of the repositories) of the packages you want to release. After passing the name of each project, you will be asked to pass a tag of the version, which will be released. At least one project name needs to be passed. When you are done with listing the needed projects, simply press enter.

sebex release plan
Project: sebex_test_b
Version: 0.10.0
Project: sebex_test_e
Version: 0.6.0
Project:

Important! All the projects updated with sebex must be Mix projects, with the @version tag inside their mix.exs file. All listed packages as well as their dependent packages will be bumped by one minor version (e.g. 0.2.1 -> 0.3.0).

Release "Purely Easy Wahoo"
===========================

1. Phase "Surely Vocal Kitten"
 * sebex_test_b, 0.2.0 -> 0.3.0, publish
 * sebex_test_e, 0.2.0 -> 0.3.0, publish
2. Phase "Easily Moved Tarpon"
 * sebex_test_c, 0.2.0 -> 0.3.0, publish
 dependencies: sebex_test_b, "~> 0.2.0" -> "~> 0.3.0"
3. Phase "Vastly Nice Impala"
 * sebex_test_d, 0.2.0 -> 0.3.0, publish
 dependencies: sebex_test_c, "~> 0.2.0" -> "~> 0.3.0"
 * sebex_test_f, 0.2.0 -> 0.3.0, publish
 dependencies:
 - sebex_test_c, "~> 0.2.0" -> "~> 0.3.0"
 - sebex_test_e, "~> 0.2.0" -> "~> 0.3.0"

Save this release? [y/N]:

The release plan will be saved inside the <workspace directory>/.sebex/release.yaml file. The release is divided into several phases. The subsequent phase can be launched, once the previous phase is finished, which is necessary due to dependencies between projects. In the first phase, we are releasing a new version of the listed projects. The later phase of the release comes with dependencies updates.

To execute the plan run:

sebex release proceed

for each phase of the plan. During the release, follow the instructions provided by sebex.

Elixir

At the moment Elixir is the only supported language.

Sebex will modify your Elixir projects by updating your project version and dependencies in the mix.exs file. Those changes will be committed to Github and tagged as a version release. To publish those updated packages to Hex you need to be logged in as an authorized Hex package maintainer on your machine.

You also need to set the HEX_API_KEY environment variable to your Hex user key. To generate the key run:

mix hex.user key generate

Only packages that were released at least once will be published automatically by Sebex to avoid publishing work-in-progress projects. However, packages belonging to the Github sebex-test-organization will always be published.

Development

We use Poetry to manage dependencies, virtual environments, and builds. Run poetry install to install all dependencies. To build wheels run make build.

Python tests are run using pytest, run pytest inside poetry shell to execute them. To run Elixir analyzer test, run mix test within its directory.
