library.json
|
|
============
|
|
|
|
``library.json`` is a manifest file of development library.
|
|
|
|
Initially it was
|
|
developed for :ref:`librarymanager`, but later was accepted by worldwide embedded
|
|
community like a **standard library specification**.
|
|
|
|
A data in ``library.json`` should be represented
|
|
in `JSON-style <http://en.wikipedia.org/wiki/JSON>`_ via
|
|
`associative array <http://en.wikipedia.org/wiki/Associative_array>`_
|
|
(name/value pairs). An order doesn't matter. The allowable fields
|
|
(names from pairs) are described below.
|
|
|
|
.. contents::
|
|
|
|
.. _libjson_name:
|
|
|
|
``name``
|
|
--------
|
|
|
|
**Required** | Type: ``String`` | Max. Length: 50
|
|
|
|
A name of the library.
|
|
|
|
* Must be unique.
|
|
* Should be slug style for simplicity, consistency and compatibility.
|
|
Example: *Arduino-SPI*
|
|
* Title Case, Aa-z, can contain digits and dashes (but not start/end
|
|
with them).
|
|
* Consecutive dashes are not allowed.
|
|
|
|
|
|
.. _libjson_description:
|
|
|
|
``description``
|
|
---------------
|
|
|
|
**Required** | Type: ``String`` | Max. Length: 255
|
|
|
|
The field helps users to identify and search for your library with a brief
|
|
description. Describe the hardware devices (sensors, boards and etc.) which
|
|
are suitable with it.
|
|
|
|
|
|
.. _libjson_keywords:
|
|
|
|
``keywords``
|
|
------------
|
|
|
|
**Required** | Type: ``String`` | Max. Length: 255
|
|
|
|
Used for search by keyword. Helps to make your library easier to discover
|
|
without people needing to know its name.
|
|
|
|
The keyword should be lowercased, can contain a-z, digits and dash (but not
|
|
start/end with them). A list from the keywords can be specified with
|
|
separator ``,``
|
|
|
|
|
|
.. _libjson_authors:
|
|
|
|
``authors``
|

|
|
|
|
* ``name`` Full name (**Required**)
|
|
* ``email``
|
|
* ``url`` An author's contact page
|
|
* ``maintainer`` Specify "maintainer" status

|
|
|
Examples:
|
|
|
|
.. code-block:: javascript
|
|
|
|
"authors":
|
|
{
|
|
"name": "John Smith",
|
|
"email": "me@john-smith.com",
|
|
"url": "http://www.john-smith/contact"
|
|
}
|
|
|
|
...
|
|
|
|
"authors":
|
|
[
|
|
{
|
|
"name": "John Smith",
|
|
"email": "me@john-smith.com",
|
|
"url": "http://www.john-smith/contact"
|
|

|
|
"url": "http://www.andrew-smith/contact",
|
|
"maintainer": true
|
|
}
|
|
]
|
|
|
|
|
|
.. note::
|
|
You can omit :ref:`libjson_authors` field and define
|
|
:ref:`libjson_repository` field. Only *GitHub-based* repository is
|
|
supported now. In this case
|
|
|PIOAPICR| will use information from
|
|
`GitHub API Users <https://developer.github.com/v3/users/>`_.
|
|
|
|
|
|
.. _libjson_repository:
|
|
|
|
``repository``
|
|
--------------
|
|
|
|
*Required* if :ref:`libjson_downloadurl` field is not defined | Type: ``Object``
|
|
|
|
The repository in which the source code can be found.
|
|
|
|
Example:
|
|
|
|
.. code-block:: javascript
|
|
|
|
"repository":
|
|
{
|
|
"type": "git",
|
|
"url": "https://github.com/foo/bar.git"
|
|
}
|
|
|
|
|
|
.. _libjson_downloadurl:
|
|
|
|
``downloadUrl``
|
|
---------------
|
|
|
|
*Required* if :ref:`libjson_repository` field is not defined | Type: ``String``
|
|
|
|
It is the *HTTP URL* to the archived source code of library. It should end
|
|
with the type of archive (``.zip`` or ``.tar.gz``).
|
|
|
|
|
|
.. _libjson_version:
|
|
|
|
``version``
|
|
-----------
|
|
|
|
*Required* if :ref:`libjson_repository` field is not defined | Type: ``String``
|
|
| Max. Length: 20
|
|
|
|
A version of the current library source code.
|
|
|
|
* Can contain a-z, digits, dots or dash.
|
|
* `Semantic Versioning <http://semver.org>`_ is recommended.
|
|
* A `CVS <http://en.wikipedia.org/wiki/Concurrent_Versions_System>`_
|
|
revision from the latest commit. Example: ``13`` (*SVN*) or first 10
|
|
chars of *SHA* digest ``e4564b7da4`` (*Git*).
|
|
|
|
.. note::
|
|
You can omit :ref:`libjson_version` field and define
|
|
:ref:`libjson_repository` field. In this case
|
|
|PIOAPICR| will use the *CVS*-revision from the latest commit.
|
|
|
|
|
|
.. _libjson_url:
|
|
|
|
``url``
|
|
-------
|
|
|
|
*Optional* | Type: ``String`` | Max. Length: 255
|
|
|
|

|
|
|
|
|
|
.. _libjson_include:
|
|
|

|
|
-----------
|
|
|
|
*Optional* | Type: ``String`` or ``Array`` |
|
|
`Glob Pattern <http://en.wikipedia.org/wiki/Glob_(programming)>`_
|
|
|
|
If :ref:`libjson_include` field is a type of ``String``, then
|
|
|PIOAPICR| will recognize it like a "relative path inside
|
|
repository/archive to library source code". See example below where the only
|
|
source code from the relative directory ``LibrarySourceCodeHere`` will be
|
|
included.
|
|
|
|
.. code-block:: javascript
|
|
|
|
"include": "some/child/dir/LibrarySourceCodeHere"
|
|
|
|
If :ref:`libjson_include` field is a type of ``Array``, then
|
|
|PIOAPICR| firstly will apply :ref:`libjson_exclude` filter and
|
|
then include only directories/files which match with :ref:`libjson_include`
|
|
patterns.
|
|
|
|
Example:
|
|
|
|
.. code-block:: javascript
|
|
|
|
"include":
|
|
[
|
|
"dir/*.[ch]pp",
|
|
"dir/examples/*",
|
|
"*/*/*.h"
|
|
]
|
|
