This module handles ruby texts. It converts between the following 4 forms:

  1. Wikitext
    [[振る|<ruby><rt></rt></ruby>り]][[仮名|<ruby><rt></rt></ruby><ruby><rt></rt></ruby>]]
    
    ()
  2. Texts of the term and the ruby
    [[振る|振り]][[仮%名]]
    
    ふりが%な
    
  3. []() markup
    [[振る|[振](ふ)り]][[仮名|[仮](が)[名](な)]]
    
  4. Lua table, used by modules
    local example_ruby_table = {
        {
            text = {
                {text = '振', ruby = 'ふ'},
                {text = 'り'},
            }, linkto = "振る"
        },
        {
            text = {
                {text = '仮', ruby = 'か'},
                {text = '名', ruby = 'な'},
            }, linkto = "仮名"
        },
    }
    

function export.to_text(ruby_table)

Concatenates the texts in a ruby table. Discards all ruby and links.

function export.to_ruby(ruby_table)

Concatenates the texts in a ruby table. Discards all links. Ruby are used in place of the text below it when present.

function export.to_markup(ruby_table, options)

Generates "[]()" markups from ruby tables.

  • options.break_link = true: Change [[...|<ruby>...<ruby>]] to <ruby>[[...]]<ruby>.
  • options.markup: Use custom markups other than "[...](...)" and "[[...|...]]". Custom markups are not recognized and can not be converted back.

function export.to_wiki(ruby_table, options)

Generates wikitexts from ruby tables.

  • The options are the same as function export.to_markup()

export.parse_markup

සංස්කරණය

function export.parse_markup(markup)

Constructs a ruby table form "[]()" markups.

function export.parse_text(term, kana, options)

Constructs a ruby table from the 2 strings passed to this function. The differences in the 2 strings are converted into ruby, with the corresponding part of kana becoming the ruby text and that of term becoming the text under the ruby. Links in term will be integrated into the result. Links in kana will be ignored by default.

Details about the format of term and kana can be found in Template:ja-r/documentation#Ruby_and_transliteration.

To better adapt to Japanese texts, this function assumes that all non-letters (except for 5 symbols "^", ".", "-", "゠", "・" for transliteration reasons) and all kana always represent themselves. These literal characters when appearing in term should also appear unchanged or as a hira-kata counterpart in kana. This behaviour can be changed by using options.try, or by manually isolating a single literal character with "%".

  • options.try == nil: Lauch an error when the assumption of literal characters fails.
  • options.try == 'force': Discard the assumption of literal characters when it fails, and try to find any differences in the strings.
  • options.try_force_limit: Limit the time used by options.try == 'force'.
  • options.space == nil: Remove spaces between kana or kanji but preserve elsewhere.
  • options.space == 'all': Preserve all spaces.
  • options.space == 'none': Remove all spaces.
  • options.allow_ruby_link == true: Try to match the links in kana.

function export.ruby_auto(args)

A shortcut for combinations like to_wiki(parse_text(...)). It accepts a table containing named arguments instead of positional ones.

  • term, kana: Arguments for parse_text().
  • markup: Argument for parse_markup().
  • to_target: Default to to_wiki(). 'text' for to_text(); 'ruby' for to_ruby(); 'markup' for to_markup().
  • options: A shared option table passed to all functions involved.

--[==[Constructs a ruby table from the 2 strings passed to this function. The differences in the 2 strings are converted into ruby, with the corresponding part of {kana} becoming the ruby text and that of {term} becoming the text under the ruby. Links in {term} will be integrated into the result. Links in {kana} will be ignored by default.
Details about the format of {term} and {kana} can be found in [[Template:ja-r/documentation#Ruby_and_transliteration]].
To better adapt to Japanese texts, this function assumes that all non-letters (except for 5 symbols "^", ".", "-", "゠", "・" for transliteration reasons) and all kana always represent themselves. These literal characters when appearing in {term} should also appear unchanged or as a hira-kata counterpart in {kana}. This behaviour can be changed by using {options.try}, or by manually isolating a single literal character with "%".
* {options.try == nil}: Lauch an error when the assumption of literal characters fails.
* {options.try == 'force'}: Discard the assumption of literal characters when it fails, and try to find any differences in the strings.
* {options.try_force_limit}: Limit the time used by {options.try == 'force'}.
* {options.space == nil}: Remove spaces between kana or kanji but preserve elsewhere.
* {options.space == 'all'}: Preserve all spaces.
* {options.space == 'none'}: Remove all spaces.
* {options.allow_ruby_link == true}: Try to match the links in {kana}.]==]
