An OBS service to replace a regex with some package version available in the build time environment or repositories.

This service makes sense mostly in buildtime mode.

Travis CI:

This is a python project that makes use of setuptools and virtual environment.

To set the development environment consider the following commands:

# Get into the repository folder
$ cd obs-service-replace_using_package_version

# Initiate the python3 virtualenv
$ python3 -m venv .env3

# Activate the virutalenv
$ source .env3/bin/activate

# Install development dependencies
$ pip install -r requirements.txt

# Run tests and code style checks
$ tox

Consider a _service file that includes the following:

<service name="replace_using_package_version" mode="buildtime">
  <param name="file">mariadb-image.kiwi</param>
  <param name="regex">%%TAG%%</param>
  <param name="package">mariadb</param>
  <param name="parse-version">minor</param>
</service>

The service in this case would look for the mariadb package in the build environment, get its version, and try to replace any occurrence of %%TAG%% in mariadb-image.kiwi file with the mariadb package version.

The parse-version states to use only up to the minor version part for a given versio string. For instance, in this specific case, the service will apply the ^(\d+(\.\d+){0,1}) regular expression and use only the first match. In case mariadb version was 10.3.4~git_r154 only the 10.3 part would be used as the replacement string.

This service is mainly designed to work in buildtime mode, so it is applied inside the build environment just before the start of the build.
