Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Library Metadata

A module can contain an optional file which describes the libraries that it contains. This is located at meta/libraries.json. It either contains a single json object for a single library, or a list or json objects for any number of libraries.

For example, for a single library:

{
    "key": "unordered",
    "name": "Unordered",
    "authors": [ "Daniel James" ],
    "maintainers": [ "Daniel James <dnljms -at- gmail.com>" ],
    "description": "Unordered associative containers.",
    "category": [
        "Containers"
    ]
}

An example for multiple libraries:

[
    {
        "key": "functional",
        "name": "Functional",
        "authors": [ "Mark Rodgers" ],
        "description": "The Boost.Function library contains a family of class templates that are function object wrappers.",
        "category": [
            "Function-objects"
        ]
    },
    {
        "key": "functional/factory",
        "name": "Functional/Factory",
        "authors": [ "Tobias Schwinger" ],
        "maintainers": [ "Tobias Schwinger <tschwinger -at- isonews2.com>" ],
        "description": "Function object templates for dynamic and static object creation",
        "documentation": "factory/",
        "category": [
            "Function-objects"
        ]
    },
]

Json fields

key

This is a unique identifier for the library, typically the path to it from the libs directory.

name

Human readable name of the library

status

Used for libraries with special statuses, currently can have value deprecated for deprecated libraries, and hidden for libraries which shouldn't be displayed to the user.

authors

Either a string, or a list of strings, containing the names of the authors

description

A brief description of what the library does

category

A list of categories that the library belongs to, the full list is below.

documentation

Path to the documentation, defaults to the root of the module.

cxxstd

The minimum C++ standard compilation level at which all, or the large majority, of the functionality in the library is usable. The possible values are:

  • 98 = C++98
  • 03 = C++98/C++03
  • 11 = C++11
  • 14 = C++14
  • 17 = C++17
  • 20 = C++20

The level only indicates the minimum level, which means that the functionality of the library can be used when compiling at that level or at a higher level. There may be some functionality in the library which will need a higher C++ standard compilation level than is indicated by this value, but the information about that specific functionality will be provided for the end-user within the documentation for that library. If a library does not have this field it indicates that the end-user will have to read the library documentation to understand what C++ standard compilation level is needed to use the library.
