    TOML

    TOML

    Tom Preston-Werner's obvious, minimal language

    Tom's Obvious, Minimal Language. By Tom Preston-Werner, Pradyun Gedam, et al. TOML aims to be a minimal configuration file format that's easy to read due to obvious semantics. TOML is designed to map unambiguously to a hash table. TOML should be easy to parse into data structures in a wide variety of languages. TOML shares traits with other file formats used for application configuration and data serialization, such as YAML and JSON. TOML and JSON both are simple and use ubiquitous data types, making them easy to code for or parse with machines. TOML and YAML both emphasize human readability features, like comments that make it easier to understand the purpose of a given line. TOML differs in combining these, allowing comments (unlike JSON) but preserving simplicity (unlike YAML). Because TOML is explicitly intended as a configuration file format, parsing it is easy, but it is not intended for serializing arbitrary data structures.

    Configuration markup language

    Human readable and human writable format for the config files

    For object-oriented programs is useful to supply the configuration information in structured manner also. Seems the XML is the an answer. But too much <tag></tag> everywhere make the XML for *.config or *.ini files almost human unreadable and uneditable. This library intended to read text of markup configurations files in uniform way. Text information from the file is loaded by your program as a structural tree. After slurping a *.config file we can supply the resulting objects to object instances of our program to let them configure themselves. So, it facilitates text information to supply configuration data to object-oriented software. Advantage - we can use markups to mark just the groups of the parameters only. And we do obliged not to keep markups for the every Name=Value pairs like XML does. Such text in *.config file is less messy, and much more human readable then XML.

    Djot

    Djot

    A light markup language

    Djot is a light markup syntax. It derives most of its features from commonmark, but it fixes a few things that make commonmark's syntax complex and difficult to parse efficiently. It is also much fuller-featured than commonmark, with support for definition lists, footnotes, tables, several new kinds of inline formatting (insert, delete, highlight, superscript, subscript), math, smart punctuation, attributes that can be applied to any element, and generic containers for block-level, inline-level, and raw content. The project began as an attempt to implement some of the ideas I suggested in Beyond Markdown.
