Python YAML

Open-source Python projects categorized as YAML

YAML is a digestible data serialization language that is often utilized to create configuration files and works in concurrence with any programming language. YAML targets many of the same communications applications as Extensible Markup Language but has a minimal syntax which intentionally differs from SGML.

Top 23 Python YAML Projects

  • jc

    CLI tool and python library that converts the output of popular command-line tools, file-types, and common strings to JSON, YAML, or Dictionaries. This allows piping of output to tools like jq and simplifying automation scripts.

    Project mention: Human redable multiline string into Json. | | 2023-01-26

    As others have mentioned you can use YAML to create the values and then convert the YAML to JSON. Here's how you can do that at the command line with jc:

    yamllint, as the name suggests, is a linter for YAML files. It checks syntax validity, as well as looking for more-complex errors like key repetition and cosmetic problems such as line length, trailing spaces, indentation etc. This one was indly recommended by yankdevil.

    Project mention: is there any difference between using string.format() or an fstring? | | 2022-10-10

    They did finally change the default, in PyYAML 6, after many many bugs pointing out that their previous approach is broken (including one by yours truly), so the default is now safe.

    The site also provide a link to the github repo of the underlying program.

  • strictyaml

    Type-safe YAML parser and validator.

    Project mention: DO YOU YAML? | | 2023-01-16

    YAML stands for "YAML Ain’t Markup Language" - this is known as a recursive acronym. YAML is often used for writing configuration files. It’s human readable, easy to understand and can be used with other programming languages. Although YAML is commonly used in many disciplines, it has received criticism on the amoutn of whitespace .yml files have, difficulty in editing, and complexity of the standard. Despite the criticism, properly using YAML ensures that you can reproduce the results of a project and makes sure that the virtual environment packages play nicely with system packages. (If you're looking for another way to share environments there are other alternatives to YAML which include StrictYAML (a type-safe YAML parser) and NestedText)

  • python-benedict

    :blue_book: dict subclass with keylist/keypath support, built-in I/O operations (base64, csv, ini, json, pickle, plist, query-string, toml, xls, xml, yaml), s3 support and many utilities.

    Project mention: What are the best Python libraries to learn for beginners? | | 2023-01-30

  • shyaml

    YAML for command line

  • Yamale

    A schema and validator for YAML.

    Project mention: Recommended ways to catch missing environment variables in github actions? | | 2023-01-10

  • nestedtext

    Human Readable and Writable Data Interchange Format

    Project mention: The yaml document from hell | | 2023-01-12

    As /u/astatine said, an excellent but under-recognized alternative syntax for configuration files is NestedText, where everything is a string unless the ingesting code says otherwise, and there is no escaping needed ever.
