Detailed Description
Constructor & Destructor Documentation
◆ __construct()
| MediaWiki\Settings\Source\FileSource::__construct | ( | string | $path, |
| SettingsFormat | $format = null ) |
Constructs a new FileSource for the given path and possibly a custom format to decode the contents.
If no format is given, the built-in formats will be tried and the first one that supports the file extension will be used.
Built-in formats:
- JsonFormat
- YamlFormat
<?php $source = new FileSource( 'my/settings.json' ); $source->load();
While a specialized caller may want to pass a specialized format
<?php $source = new FileSource( 'my/settings.toml', new TomlFormat() ); $source->load();
- Parameters
-
string $path SettingsFormat | null $format

◆ locateInclude()
| MediaWiki\Settings\Source\FileSource::locateInclude | ( | string | $location | ) |
This method defines how a relative reference to the location of another settings source is interpreted.
It tries to make $location absolute by interpreting it as relative to the location of the SettingsSource it originates from.
Implementation are "best effort". If a location cannot be made absolute, it may be returned as-is. Implementations are also free to throw a SettingsBuilderException to indicate that the given include location is not supported in this context.
- Parameters
-
string $location
- Returns
- string
- Exceptions
-
SettingsBuilderException if the given location cannot be used as an include by the current source.
Implements MediaWiki\Settings\Source\SettingsIncludeLocator.
