CRENDER

Version

This is version 0.1.

General

This is a small tool intended to do linting, pre-rendering, and analysis of conda recipes. It supports some jinja2 features (be aware it doesn't support full python-language feature) It outputs files in yaml format.

Acquiring

Assuming a checkout from git, ensure submodules are updated: git submodule update --init

Building

Just use cmake as you normally would. For example:

mkdir Build && \
cd Build && \
cmake .. -G"Ninja" -DCMAKE_BUILD_TYPE=Release && \
ninja

Note that Windows isn't yet completely supported, though it's probably a trivial change.

Installing

The crender binary assumes there is a data/ directory either colocated with the execuable or at some level above it. If you move crender, don't forget to also move the data/ directory and its content accordingly.

Usage

Example (querying all of the feedstocks for linux-aarch64):

./bin/crender -a linux-aarch64 -o ./output_linux-aarch64 -i -S -p 3.8 ../aggregate/*-feedstock

NB1: You can specify multiple python versions using the -p parameter, and multiple architectures/subdirs with the -a parameter.

Outputs

info_envs.yaml - Lists environment variables set by feedstocks' meta.yaml files.

info_notes.yaml - Tells you for each recipe things that might be wrong. Like a linter.

nfo_o2p.yaml - "Output to package." The individual output from a recipe, and underneath that is the recipe from which it came. Example:

    libcurl:
      - curl_split_recipe
    curl:
      - curl_split_recipe
    curl_split_recipe:
      - curl_split_recipe

- Basically tells you which output belongs to which recipe.

info_p_dependson.yaml - "This package depends on the following packages."

info_p_dependson.yaml - Splits up by dependency type/kind (e.g. build, host, run, test).

info_p_usedby.yaml - "All these packages use this package" (represented by the key).

info_pv.yaml - Specific versions of packages used among the feedstocks scanned in AnacondaRecipes.

info_pv2o.yaml - "This recipe version produces these outputs." Example:

    curl_split_recipe 7.71.1:
      - libcurl
      - curl
      - curl_split_recipe

info_urls.yaml - Maps URLs (in the meta.yamls) to their types (e.g. source, home, dev, doc). - Can be used to verify the URLs are valid.
