# Azure template for installing dependencies from various package managers,
# necessary for building, testing, and packaging OpenTitan.
#
# This template can be included from pipelines in other repositories.
# In this case, set the the REPO_TOP parameter to point to the root of the
# checked out opentitan repository.
#
# This template executes:
# - apt-get install for all packages listed in apt-requirements.txt
# - pip install for all packages listed in python-requirements.txt

parameters:
- name: REPO_TOP
  type: string
  default: .

steps:
  - bash: |
      set -e

      cd "${{ parameters.REPO_TOP }}"

      # Ensure apt package index is up-to-date.
      sudo apt-get update

      # NOTE: We use sed to remove all comments from apt-requirements.txt,
      # since apt-get doesn't actually provide such a feature.
      sed 's/#.*//' apt-requirements.txt \
        | xargs sudo apt-get install -y

      # Python requirements are installed to the local user directory so prepend

      export PATH=$HOME/.local/bin:$PATH

      # Explicitly installing six is a workaround for pip dependency resolution:
      # six is already installed as system package with a version below the
      # required one.  Explicitly installing six through pip gets us a supported
      # version.
      #
      # Explicitly updating pip and setuptools is required to have these tools
      # properly parse Python-version metadata, which some packages uses to
      # specify that an older version of a package must be used for a certain
      # Python version. If that information is not read, pip installs the latest
      # version, which then fails to run.
      pip3 install --user -U setuptools pip six
      pip3 install --user -U -r python-requirements.txt
