IAL-build

Tools for Source Code Management and build of IAL code.

This package wraps around IAL git repo management, bundling (ecbundle package) and build systems (for now gmkpack only) to help transitioning from source code to IAL binary executables. It provides a python package to do so, as well as a set of command-line tools.

Dependencies

• ecbundle : https://github.com/ecmwf/ecbundle --- (quick install: pip3 install --user git+https://github.com/ecmwf/ecbundle)
• Some functionalities may also clone and use IAL-bundle, especially for the research of "official" bundles for main cycles. If you don't have internet connection at time of use, you may have to specify a local, pre-cloned, origin repository for IAL-bundle, using env variable DEFAULT_IALBUNDLE_REPO, e.g. DEFAULT_IALBUNDLE_REPO=~/repositories/IAL-bundle, or specifying it using command-line options, cf. help with option -h.

Installation

pip install ial-build

Documentation

Cache directory:

When using a bundle (and ecbundle), the repositories are cloned/downloaded in a sort of cache directory, so as to speed-up the next use: only a fetch of the requested branch or git reference will be done. The requested git reference is then checkedout in this cache repository, before being copied/cloned into the pack (in the case of gmkpack).

Tools

When installed with pip, a bunch of ial-* commands are available in order to :

• help finding bundles (ial-find_bundle, ial-get_bundle)
• make packs (gmkpack) from bundles or IAL branches (ial-git2pack, ial-bundle2pack). They are auto-documented, see their argument -h.

Some examples:

Prepare a bundle for a personal branch

• Find a bundle appropriate for my IAL branch <my_branch>, based on CY50:

  % ial-find_bundle my_branch
  BDL50-default
  

• Get this bundle:

  % ial-get_bundle BDL50-default [-t my_bundle.yml]
  

• Edit and replace CY50 in my_bundle.yml

• Create a root pack from my bundle:

  % ial-bundle2pack my_bundle.yml [...pack creation arguments, cf. -h]
  

Install a root pack of BDL50-default

ial-bundle2pack BDL50-default

will:

• look for a bundle tagged BDL50-default in the IAL-bundle repository,
• download it
• clone/fetch/checkout each package referenced in the bundle in the requested version, in a cache local directory (cf. option -d)
• create a pack (by default: main)
• populate the pack with the source codes checkedout for each package

Install a root(=main) pack for the recommended (default) bundle for CY50

ial-git2pack -t main CY50 [...]

will:

• find a bundle appropriate for CY50 in IAL-bundle repository
• then do the same as ial-bundle2pack

Install an incremental pack with the content of my IAL branch on top of its most recent official ancestor pack

ial-git2pack my_branch

Install a pack with a modified branch in oops only

1. get a local copy of a bundle file that fits the basis of your development, e.g.

ial-find_bundle --get_copy CY50

2. rename and edit your bundle file, setting your (potentially local) oops repository and branch
3. in the bundle file still, set attribute incremental_pack of the oops_src project to True
4. create your pack using

   ial-bundle2pack <my_bundle.yml> -t incr
