模組:Lang/sandbox
这是Module:Lang(差异)的沙盒。 参见本模块的测试样例(运行)。 |
此模块sandbox被引用於許多頁面。 為了避免造成大規模的影響,所有對此模块sandbox的編輯應先於沙盒或測試樣例上測試。 測試後無誤的版本可以一次性地加入此模块sandbox中,但是修改前請務必於討論頁發起討論。 模板引用數量會自動更新。 |
該模塊主要用於為中文維基百科中使用該文本的非中文文本提供正確的html標記。 它的第二個目的是為這個此文本提供正確的視覺渲染。 該模塊將{{lang}}
和許多{{lang-??}}
模板的處理合併為一個單一來源,並使用從國際標準中提取的明確定義的數據集。
數據集在Module:Language/name/data及其包含的數據模塊中指定:
- 關於語言代碼和名稱的資料(language code-and-name data)
- Module:Language/data/iana languages – 來自 IANA 的語言子標籤註冊表檔案
- Module:Language/data/ISO 639-3 – 來自 sil.org 的 UTF-8 完整的代碼表集合
- 關於語言之書寫系統的資料(language script data)
- Module:Language/data/iana scripts – 來自 IANA 的語言子標籤註冊表檔案
- 關於語言之所在區域的資料(language region data)
- Module:Language/data/iana regions – 來自 IANA 的語言子標籤註冊表檔案
- 關於語言之變體的資料(language variant data)
- Module:Language/data/iana variants – 來自 IANA 的語言子標籤註冊表檔案
- suppressed-script data
- Module:Language/data/iana suppressed scripts – 來自 IANA 的語言子標籤註冊表檔案
該數據集還包括補充數據模塊:
- 重寫和其他非標準數據(override and other non-standard data)
- Module:Lang/data – 例如,當IANA不同意ISO 639-3或標準語言名稱很麻煩或包含不適合在文章空間中使用的信息時,
override
表可以保存該語言信息;在中文维基此子模块包括各语言名称的中文显示功能,如果语言名称显示为英文或显示不正确请在此添加或修改中文名覆盖 - Module:Lang/ISO 639 synonyms – 將使用三個字符的ISO 639-2,-2T,-3代碼映射到只使用兩個字符的ISO 639-1代碼 – 來自 語言名稱表示法規範(Codes for the Representation of Names of Languages)。
該模塊不需要無數的 {{ISO 639 name ??}}
模板、{{Language with name}}
、{{Language with name and transliteration}}
和{{transl}}
。它亦提供了錯誤檢查和報告,以確保呈現的HTML對於瀏覽器和屏幕閱讀器是正確的。

This function attempts to invert the italic markup a args.text by adding/removing leading/trailing italic markup
in args.text. Like |italic=unset, |italic=invert disables automatic italic markup. Individual leading/trailing
apostrophes are converted to their html numeric entity equivalent so that the new italic markup doesn't become
bold markup inadvertently.
Leading and trailing wiki markup is extracted from args.text into separate table elements. Addition, removal,
replacement of wiki markup is handled by a string.gsub() replacement table operating only on these separate elements.
In the string.gsub() matching pattern, '.*' matches empty string as well as the three expected wiki markup patterns.
This function expects that markup in args.text is complete and correct; if it is not, oddness may result.

Validates |italic= or |italics= assigned values.
When |italic= is set and has an acceptible assigned value, return the matching css font-style property value or,
for the special case 'default', return nil.
When |italic= is not set, or has an unacceptible assigned value, return nil and a nil error message.
When both |italic= and |italics= are set, returns nil and a 'conflicting' error message.
The return value nil causes the calling lang, lang_xx, or transl function to set args.italic according to the template's
defined default ('inherit' for {{lang}}, 'inherit' or 'italic' for {{lang-??}} depending on
the individual template's requirements, 'italic' for {{transliteration}}) or to the value appropriate to |script=, if set ({{lang}}
and {{lang-??}} only).
Accepted values and the values that this function returns are are:
nil - when |italic= absent or not set; returns nil
default - for completeness, should rarely if ever be used; returns nil
yes - force args.text to be rendered in italic font; returns 'italic'
no - force args.text to be rendered in normal font; returns 'normal'
unset - disables font control so that font-style applied to text is dictated by markup inside or outside the template; returns 'inherit'

Default behavior of the {{lang}} and {{lang-??}} templates is to add categorization when the templates are used in mainspace.
This default functionality may be suppressed by setting |nocat=yes or |cat=no. This function selects one of these two parameters
to control categorization.
Because having two parameters with 'opposite' names and 'opposite' values is confusing, this function accepts only affirmative
values for |nocat= and only negative values for |cat=; in both cases the 'other' sense (and non-sense) is not accepted and the
parameter is treated as if it were not set in the template.
Sets args.nocat to true if categorization is to be turned off; to nil if the default behavior should apply.
Accepted values for |nocat= are the text strings:
'yes', 'y', 'true', 't', on, '1' -- [[Module:Yesno]] returns logical true for all of these; false or nil else
for |cat=
'no', 'n', 'false', 'f', 'off', '0' -- [[Module:Yesno]] returns logical false for all of these; true or nil else

Extracts and returns IETF language tag parts:
primary language subtag (required) - 2 or 3 character IANA language code
script subtag - four character IANA script code
region subtag - two-letter or three digit IANA region code
variant subtag - four digit or 5-8 alnum variant code; only one variant subtag supported
private subtag - x- followed by 1-8 alnum private code; only supported with the primary language tag
in any one of these forms
lang lang-variant
lang-script lang-script-variant
lang-region lang-region-variant
lang-script-region lang-script-region-variant
lang-x-private
each of lang, script, region, variant, and private, when used, must be valid.
Languages with both two- and three-character code synonyms are promoted to the two-character synonym because
the IANA registry file omits the synonymous three-character code; we cannot depend on browsers understanding
the synonymous three-character codes in the lang= attribute.
For {{lang-??}} templates, the parameters |script=, |region=, and |variant= are supported (not supported in {{lang}}
because those parameters are superfluous to the IETF subtags in |code=).
Returns six values; all lower case. Valid parts are returned as themselves; omitted parts are returned as empty strings, invalid
parts are returned as nil; the sixth returned item is an error message (if an error detected) or nil.

The value |script= is not used in {{transliteration}} for this purpose; instead it uses |code. Because language scripts
are listed in the {{transliteration}} switches they are included in the data tables. The script parameter is introduced
at {{Language with name and transliteration}}. If |script= is set, this function uses it in preference to code.
To avoid confusion, in this module and the templates that use it, the transliteration script parameter is renamed
to be |translit-script= (in this function, tscript).

lang_xx() always provides code, language_name, and translit; may provide tscript; never provides style

For the {{lang-??}} templates, the only parameter required to be set in the template is the language code. All
other parameters can, usually should, be written in the template call. For {{lang-??}} templates for languages
that can have multiple writing systems, it may be appropriate to set |script= as well.
For each {{lang-??}} template choose the appropriate entry-point function so that this function knows the default
styling that should be applied to text.
For normal, upright style:
<includeonly>{{#invoke:lang|lang_xx_inherit|code=xx}}</includeonly>
For italic style:
<includeonly>{{#invoke:lang|lang_xx_italic|code=xx}}</includeonly>
All other parameters should be received from the template's frame (parent frame)
Supported parameters are:
|code = (required) the IANA language code
|script = IANA script code; especially for use with languages that use multiple writing systems
|region = IANA region code
|variant = IANA variant code
|text = (required) the displayed text in language specified by code
|link = boolean false ('no') does not link code-spcified language name to associated language article
|rtl = boolean true ('yes') identifies the language specified by code as a right-to-left language
|nocat = boolean true ('yes') inhibits normal categorization; error categories are not affected
|cat = boolian false ('no') opposite form of |nocat=
|italic = boolean true ('yes') renders displayed text in italic font; boolean false ('no') renders displayed text in normal font; not set renders according to initial_style_state
|lit = text that is a literal translation of text
|label = 'none' to suppress all labeling (language name, 'translit.', 'lit.')
any other text replaces language-name label - automatic wikilinking disabled
for those {{lang-??}} templates that support transliteration (those templates where |text= is not entirely latn script):
|translit = text that is a transliteration of text
|translit-std = the standard that applies to the transliteration
|translit-script = ISO 15924 script name; falls back to code
For {{lang-??}}, the positional parameters are:
{{{1}}} text
{{{2}}} transliterated text
{{{3}}} literal translation text
no other positional parameters are allowed

{{lang-xx |<text> |<transl> |<xlate> }}

positional parameters.
{{lang-??}} depends on the calling template to select 'inherit' or 'italic' to establish the default rendering.
{{langx}} can't do that. The initial version of {{langx}} relied on a list of language tags (inherit_t in ~/langx)
scraped from those {{lang-??}} templates that call lang_xx_inherit() to render text in upright font. Langx now
