@ -5,6 +5,33 @@ All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased](https://git.rustybever.be/vieter/vieter/src/branch/dev)
## [0.3.0-alpha.2](https://git.rustybever.be/vieter/vieter/src/tag/0.3.0-alpha.2)
### Added
* Web API for adding & querying build logs
* CLI commands to access build logs API
* Cron build logs are uploaded to above API
* Proper ASCII table output in CLI
* `vieter repos build id` command to run builds locally
### Removed
* `vieter build` command
* This command was used alongside cron for periodic builds, but this has
been replaced by `vieter cron`
### Changed
* `vieter build` command now only builds a single repository & uploads the
build logs
* Official Arch packages are now split between `vieter` & `vieter-git`
* `vieter` is the latest release
* `vieter-git` is the latest commit on the dev branch
* Full refactor of Docker socket code
## [0.3.0-alpha.1](https://git.rustybever.be/vieter/vieter/src/tag/0.3.0-alpha.1)

previously created image as a base. Each container goes through the following steps:
1. The repository is cloned

2. `makepkg --nobuild --syncdeps --needed --noconfirm` is ran to update the `pkgver` variable inside

This module provides a framework for parsing a configuration, defined as a
struct, from both a TOML configuration file & environment variables. Some
notable features are:
* Overwrite values in config file using environment variables
* Allow default values in config struct
* Read environment variable value from file
