export.format_audio

function export.format_audio(data)

Display a box that can be used to play an audio file. data is a table containing the following fields:

• lang (required): language object for the audio files;
• file (required): file containing the audio;
• caption: Caption to display before the audio box; normally "Audio", and does not usually need to be changed;
• nocaption: If specified, don't display the caption;
• q: nil or a list of left regular qualifier strings, formatted using format_qualifier() in Module:qualifier and displayed before the audio box and after the caption (and any accent qualifiers);
• qq: nil or a list of right regular qualifier strings, displayed directly after the audio box (and after any accent qualifiers);
• a: nil or a list of left accent qualifier strings, formatted using format_qualifiers() in Module:accent qualifier and displayed before the audio box and after the caption;
• aa: nil or a list of right accent qualifier strings, displayed directly after the homophone in question;
• refs: nil or a list of references or reference specs to add directly after the audio box; the value of a list item is either a string containing the reference text (typically a call to a citation template such as {{cite-book}}, or a template wrapping such a call), or an object with fields text (the reference text), name (the name of the reference, as in <ref name="foo">...</ref> or <ref name="foo" />) and/or group (the group of the reference, as in <ref name="foo" group="bar">...</ref> or <ref name="foo" group="bar"/>); this uses a parser function to format the reference appropriately and insert a footnote number that hyperlinks to the actual reference, located in the <references /> section;
• text: Text of the audio snippet; if specified, should be an object of the form passed to full_link() in Module:links, including a lang field containing the language of the text (usually the same as data.lang); displayed before the audio box, after any regular and accent qualifiers;
• IPA: IPA of the audio snippet, or a list of IPA specs; if specified, should be surrounded by slashes or brackets, and will be processed using format_IPA_multiple() in Module:IPA and displayed before the audio box, after any regular and accent qualifiers and after the text of the audio snippet, if given;
• nocat: If true, suppress categorization;
• sort: Sort key for categorization.

export.format_multiple_audios

function export.format_multiple_audios(data)

FIXME: Old entry point for formatting multiple audios in a single table. Not used anywhere and needs rewriting to the standard of format_audio().

Meant to be called from a module. data is a table containing the following fields:

 <syntaxhighlight lang=lua>
  lang = LANGUAGE_OBJECT,
  audios = {{file = "FILENAME", qualifiers = nil or {"QUALIFIER", "QUALIFIER", ...}}, ...},
  caption = nil or "CAPTION"
</syntaxhighlight> 

Here:

• lang is a language object.
• audios is the list of audio files to display. FILENAME is the name of the audio file without a namespace. QUALIFIER is a qualifier string to display after the specific audio file in question, formatted using format_qualifier() in Module:qualifier.
• caption, if specified, adds a caption before the audio file.

export.construct_audio_textobj

function export.construct_audio_textobj(args)

Construct the text object passed into format_audio(), from raw-ish arguments (essentially, the output of process() in Module:parameters). On entry, args contains the following fields:

• lang (required): Language object.
• text: Text. If this isn't defined and neither are any of t, tr, ts, pos, lit or g, the function returns nil.
• t: Gloss of text.
• tr: Manual transliteration of text.
• ts: Transcription of text.
• pos: Part of speech of text.
• lit: Literal meaning of text.
• g: Gender/number spec(s) of text. Automatically split on commas.
• sc: Optional script object of text (rarely needs to be set).
• pagename: Pagename; used in place of text when text is unset but other text-related parameters are set. If not specified, taken from the actual pagename.

export.show

function export.show(frame)

Entry point for {{audio}} template.

Display a box that can be used to play an audio file. `data` is a table containing the following fields:
* `lang` ('''required'''): language object for the audio files;
* `file` ('''required'''): file containing the audio;
* `caption`: Caption to display before the audio box; normally {"Audio"}, and does not usually need to be changed;
* `nocaption`: If specified, don't display the caption;
* `q`: {nil} or a list of left regular qualifier strings, formatted using {format_qualifier()} in [[Module:qualifier]]
  and displayed before the audio box and after the caption (and any accent qualifiers);
* `qq`: {nil} or a list of right regular qualifier strings, displayed directly after the audio box (and after any
  accent qualifiers);
* `a`: {nil} or a list of left accent qualifier strings, formatted using {format_qualifiers()} in
  [[Module:accent qualifier]] and displayed before the audio box and after the caption;
* `aa`: {nil} or a list of right accent qualifier strings, displayed directly after the homophone in question;
* `refs`: {nil} or a list of references or reference specs to add directly after the audio box; the value of a list item
  is either a string containing the reference text (typically a call to a citation template such as {{tl|cite-book}}, or
  a template wrapping such a call), or an object with fields `text` (the reference text), `name` (the name of the
  reference, as in {{cd|<nowiki><ref name="foo">...</ref></nowiki>}} or {{cd|<nowiki><ref name="foo" /></nowiki>}})
  and/or `group` (the group of the reference, as in {{cd|<nowiki><ref name="foo" group="bar">...</ref></nowiki>}} or
  {{cd|<nowiki><ref name="foo" group="bar"/></nowiki>}}); this uses a parser function to format the reference
  appropriately and insert a footnote number that hyperlinks to the actual reference, located in the
  {{cd|<nowiki><references /></nowiki>}} section;
* `text`: Text of the audio snippet; if specified, should be an object of the form passed to {full_link()} in
  [[Module:links]], including a `lang` field containing the language of the text (usually the same as `data.lang`);
  displayed before the audio box, after any regular and accent qualifiers;
* `IPA`: IPA of the audio snippet, or a list of IPA specs; if specified, should be surrounded by slashes or brackets,
  and will be processed using {format_IPA_multiple()} in [[Module:IPA]] and displayed before the audio box, after any
  regular and accent qualifiers and after the text of the audio snippet, if given;
* `nocat`: If true, suppress categorization;
* `sort`: Sort key for categorization.
