Test JavaScript YAML parsers

Compare 3 YAML parsers available in the JS ecosystem:

• https://github.com/jeremyfa/yaml.js
• https://github.com/nodeca/js-yaml
• https://github.com/eemeli/yaml

Usage

• ./run.sh - runs test cases specified in index.js on all YAML parsers, resulting in log files written to results/:

  results/
  ├── js-yaml.txt
  ├── yaml-1.1.txt
  ├── yaml-1.2.txt
  └── yamljs.txt
  

• ./gen-results-diffs.sh - generates the results-diffs/ folder with diffs between logs in results/

• ./parse.sh <ks_base_dir> - parses 3 sets of YAML files, converts them to JSON and writes .json files to out/:

  • https://github.com/kaitai-io/kaitai_struct_formats
  • https://github.com/kaitai-io/kaitai_struct_tests/tree/master/formats
  • https://github.com/kaitai-io/kaitai_struct_tests/tree/master/formats_err

  Requires the <ks_base_dir> parameter (path to a full clone of https://github.com/kaitai-io/kaitai_struct).

  The resulting folder structure looks like this:

  out/
  ├── js-yaml/
  │   ├── ksf/
  │   ├── kst/
  │   └── kst_err/
  ├── yaml-1.1/
  │   └── ...
  ├── yaml-1.2/
  │   └── ...
  └── yamljs/
      └── ...
  

  This makes it easy to compare the results of YAML parsers between each other, for example:

  git diff --no-index -- out/{yamljs,js-yaml}/
