Each component must have a component.json in JSON format that
describes the main information about itself. The file must be structured
as a single object which corresponds to a PHP array once unserialized
with json_decode(). Each key/value pair of the object is an array
key/value entry. The format is under development and may change further.
Note that, when using the adminstyle plugin for bibliographic styles, the component.json file is automatically created for you when creating a new style and updated when editing a style.
Description of fields:
| Field | Type | M | Description |
|---|---|---|---|
| component_type | string | Y | Name of a type of component. Must be: plugin, style, or template. |
| component_id | string | Y | Component identifier. Must be identical to the name of the root component directory. |
| component_version | string | Y | Component public version number: this integer is up to you, but should increase with new releases. It is recommended to use \UTILS\computeComponentVersion() function to choose this number. |
| component_name | string | Y | Component short name. |
| component_longname | string | Y | Component long name. |
| component_description | string | Y | Component short description (without line break). Use the README.txt file for long description, notes… |
| component_licence | string | N | Component license name or abbreviation (abbreviation recommended). |
| component_website | string | N | A single full URL to the maintainer website to use as a link. |
| component_sha256 | string | Y | Unique signature corresponding to a sha256 hash of the component files. Use cli-sign-components.php in the top level of the wikindx folder to compute it. |
| component_authors | array | N | An array of objects that, unserialized, will be a PHP array of PHP arrays. Each object is an author or contributor. |
| author_name | string | Y | Name of the author. |
| author_role | string | Y | Role of the author. Something like: developer, packager, translator, tester, maintainer. |
| author_copyright | string | Y | Contribution period. E.g. the years: 2004-2017. |
| author_email | string | Y | A single email address of the author that could be embedded in a href with mailto. |
| author_website | string | Y | A single full URL to the author website/personal page to use as a link. |
Column M indicates a mandatory field: Y=Yes, N=No.
Any additional fields will be ignored.
For the exact syntax of each data type, consult the official format specifications for JSON.
When WIKINDX starts or the components admin panel is opened a
components.json file is created in the cache folder, and a
components.json file is created in the data folder.
The file in cache folder, listing all components installed, is an array
of objects in JSON format. Each object is the content of a
component.json file with additional fields. Original component.json
fields remain unchanged.
| Field | Type | M | Description |
|---|---|---|---|
| component_integrity | integer | Y | Error code returned when the component is checked. 0 is OK. Not 0 is an error. |
The file in data folder, listing persistent data of some components, is
an array of objects in JSON format. Each object is a short component
description (component_type + component_id) like a component.json file
with additional persistent fields. This list can contain data about
components that are no longer installed but that we want to keep for a
future reinstallation. Original component.json fields remain unchanged.
| Field | Type | M | Description |
|---|---|---|---|
| component_status | string | Y | Code status value: enabled or disabled. “enabled”, if the component is executed on WIKINDX startup. |
When the release script release/cli-make-package.php script is executed, it creates
also a components.json, listing all components released with the current
core.
As with the previous file, it is an array of objects in JSON format. Each
object is the content of a component.json file with additional fields,
but different. Original component.json fields remain unchanged.
| Field | Type | M | Description |
|---|---|---|---|
| component_packages | array | N | Array of object. Each object is the description of a downloadable package of the component. |
| package_location | string | Y | A single full URL to a downloadable package in zip format. |
| package_sha256 | string | Y | Unique signature corresponding to a sha256 hash of the package generated by make.php. |
| package_size | integer | Y | Size in bytes of the package. |

From WIKINDX v6.6.0, the support of vendor components type is removed. Vendor components have been merged with core.
From WIKINDX v6.4.11, the component_builtin and component_updatable fields have been removed. From WIKINDX v6.3.5, the support of language components type is removed. Translations are stored in core and plugin components directly.
