Format a line of one or more IPA pronunciations as {{tl|IPA}} would do it, i.e. with a preceding {"IPA:"} followed by
the word {"key"} linking to an Appendix page describing the language's phonology, and with an added category
{{cd|<var>lang</var> terms with IPA pronunciation}}. Other than the extra preceding text and category, this is identical
to {format_IPA_multiple()}, and the considerations described there in the documentation apply here as well. There is a
single parameter `data`, an object with the following fields:
* `lang`: Object representing the language of the pronunciations, which is used when adding cleanup categories for
pronunciations with invalid phonemes; for determining how many syllables the pronunciations have in them, in order to
add a category such as [[:Category:Italian 2-syllable words]] (for certain languages only); for adding a category
{{cd|<var>lang</var> terms with IPA pronunciation}}; and for determining the proper sort keys for categories. Unlike
for {format_IPA_multiple()}, `lang` may not be {nil}.
* `items`: List of pronunciations, in exactly the same format as for {format_IPA_multiple()}.
* `err`: If not {nil}, a string containing an error message to use in place of the link to the language's phonology.
* `separator`: The default separator to use when separating formatted items. Defaults to {", "}. Does not apply to the
first item, where the default separator is always the empty string. Overridden by the per-item `separator` field in
`items`.
* `sort_key`: Explicit sort key used for categories.
* `no_count`: Suppress adding a {#-syllable words} category such as [[:Category:Italian 2-syllable words]]. Note that
only certain languages add such categories to begin with, because it depends on knowing how to count syllables in a
given language, which depends on the phonology of the language. Also, this does not suppress the addition of cleanup
or other categories. If you need them suppressed, use `split_output` to return the categories separately and ignore
them.
* `split_output`: If not given, the return value is a concatenation of the formatted pronunciation and formatted
categories. Otherwise, two values are returned: the formatted pronunciation and the categories. If `split_output` is
the value {"raw"}, the categories are returned in list form, where the list elements are a combination of category
strings and category objects of the form suitable for passing to {format_categories()} in [[Module:utilities]]. If
`split_output` is any other value besides {nil}, the categories are returned as a pre-formatted concatenated string.
* `include_langname`: If specified, prefix the result with the language name, followed by a colon.
* `q`: {nil} or a list of left qualifiers (as in {{tl|q}}) to display at the beginning, before the formatted
pronunciations and preceding {"IPA:"}.
* `qq`: {nil} or a list of right qualifiers to display after all formatted pronunciations.
* `a`: {nil} or a list of left accent qualifiers (as in {{tl|a}}) to display at the beginning, before the formatted
pronunciations and preceding {"IPA:"}.
* `aa`: {nil} or a list of right accent qualifiers to display after all formatted pronunciations.

--[==[
Format a line of one or more bare IPA pronunciations (i.e. without any preceding {"IPA:"} and without adding to a
category {{cd|<var>lang</var> terms with IPA pronunciation}}). Individual pronunciations are formatted using
{format_IPA()} and are combined with separators, qualifiers, pre-text, post-text, etc. to form a line of pronunciations.
Parameters accepted are:
* `lang` is an object representing the language of the pronunciations, which is used when adding cleanup categories for
pronunciations with invalid phonemes; for determining how many syllables the pronunciations have in them, in order to
add a category such as [[:Category:Italian 2-syllable words]] (for certain languages only); and for computing the
proper sort keys for categories. `lang` may be {nil}.
* `items` is a list of pronunciations, each of which is an object with the following properties:
** `pron`: the pronunciation, in the same format as is accepted by {format_IPA()}, i.e. it should be either phonemic
(surrounded by {/.../}), phonetic (surrounded by {[...]}), orthographic (surrounded by {⟨...⟩}) or a rhyme
(beginning with a hyphen);
** `pretext`: text to display directly before the formatted pronunciation, inside of any qualifiers or accent
qualifiers;
** `posttext`: text to display directly after the formatted pronunciation, inside of any qualifiers or accent
qualifiers;
** `q` or `qualifiers`: {nil} or a list of left qualifiers (as in {{tl|q}}) to display before the formatted
pronunciation; note that `qualifiers` is deprecated;
** `qq`: {nil} or a list of right qualifiers to display after the formatted pronunciation;
** `a`: {nil} or a list of left accent qualifiers (as in {{tl|a}}) to display before the formatted pronunciation;
** `aa`: {nil} or a list of right accent qualifiers to after before the formatted pronunciation;
** `refs`: {nil} or a list of references or reference specs to add after the pronunciation and any posttext and
qualifiers; 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;
** `gloss`: {nil} or a gloss (definition) for this item, if different definitions have different pronunciations;
** `pos`: {nil} or a part of speech for this item, if different parts of speech have different pronunciations;
** `separator`: the separator text to insert directly before the formatted pronunciation and all qualifiers, accent
qualifiers and pre-text; defaults to the outer `separator` parameter.
* `separator`: The default separator to use when separating formatted items. Defaults to {", "}. Does not apply to the
first item, where the default separator is always the empty string. Overridden by the per-item `separator` field in
`items`.
* `no_count`: Suppress adding a {#-syllable words} category such as [[:Category:Italian 2-syllable words]]. Note that
only certain languages add such categories to begin with, because it depends on knowing how to count syllables in a
given language, which depends on the phonology of the language. Also, this does not suppress the addition of cleanup
categories. If you need them suppressed, use `split_output` to return the categories separately and ignore them.
* `split_output`: If not given, the return value is a concatenation of the formatted pronunciation and formatted
categories. Otherwise, two values are returned: the formatted pronunciation and the categories. If `split_output` is
the value {"raw"}, the categories are returned in list form, where the list elements are a combination of category
strings and category objects of the form suitable for passing to {format_categories()} in [[Module:utilities]]. If
`split_output` is any other value besides {nil}, the categories are returned as a pre-formatted concatenated string.

Format an IPA pronunciation. This wraps the pronunciation in appropriate CSS classes and adds cleanup categories and
error messages as needed. The pronunciation `pron` should be either phonemic (surrounded by {/.../}), phonetic
(surrounded by {[...]}), orthographic (surrounded by {⟨...⟩}), a rhyme (beginning with a hyphen) or a combined
phonemic/phonetic spec (of the form {/.../ [...]}). `lang` indicates the language of the pronunciation and can be {nil}.
If not {nil}, and the specified language has data in [[Module:IPA/data]] indicating the allowed phonemes, then the page
will be added to a cleanup category and an error message displayed next to the outputted pronunciation. Note that {lang}
also determines sort key processing in the added cleanup categories. If `split_output` is not given, the return value is
a concatenation of the formatted pronunciation, error messages and formatted cleanup categories. Otherwise, three values
are returned: the formatted pronunciation, the cleanup categories and the concatenated error messages. If `split_output`
is the value {"raw"}, the cleanup categories are returned in list form, where the list elements are a combination of
category strings and category objects of the form suitable for passing to {format_categories()} in [[Module:utilities]].
If `split_output` is any other value besides {nil}, the cleanup categories are returned as a pre-formatted concatenated
string.

Format a line of one or more enPR pronunciations as {{tl|enPR}} would do it, i.e. with a preceding {"enPR:"} (linked to
[[Appendix:English pronunciation]]) followed by one or more formatted, comma-separated enPR pronunciations. The
pronunciations are formatted by wrapping them in the {{cd|AHD}} and {{cd|enPR}} CSS classes and adding any left and
right regular and accent qualifiers. In addition, the overall result is wrapped in any overall left and right regular
