This module implements the {{listen}} template.
Usage from wikitext
This module cannot be used directly from wikitext. It can only be used through the {{listen}} template. Please see the template page for documentation.
Usage from Lua modules
To use this module from other Lua modules, first load the module.
local mListen = require('Module:Listen')
You can then generate the listen box by using the _main function.
mListen._main(args)
The args variable should be a table containing the arguments to pass to the module. To see the different arguments that can be specified and how they affect the module output, please refer to the {{listen}} template documentation.
Tracking/maintenance categories
- Category:Articles with hAudio microformats
- Category:Articles with empty listen template
- Category:Listen template using plain parameter
