Template:ISO 639 name

Template documentation[view] [edit] [history] [purge]

This template is used on approximately 27,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template uses Lua:

Module:ISO 639 name (sandbox)

This template may be used to convert a language name (e.g. 'Spanish' or 'German') to an ISO 639 language code ('es' or 'de', respectively) and vice-versa, or to determine if a given code or language is valid in ISO 639.

Usage

{{ISO 639 name|ISO code}}
{{ISO 639 name|fn=iso_639_code_to_name|ISO code}}
{{Iso 639 name|fn=iso_639_name_to_code|Language name}}
{{ISO 639 name|fn=iso_639|ISO code or language name|link=yes|hide-err=yes}}
{{iso 639 name|fn=iso_639_code_exists|ISO code}}

Parameters

There is one required parameter and four optional parameters:

|1= – unnamed (positional) param: either an ISO 639 language code, or an ISO 639 language name (required)
|fn= – function name: identifies what to do with the code or name in param 1 (convert it, check if it exists; etc.) (optional). These are the most commonly used values:
- iso_639_code_to_name – convert the ISO 639 code in param 1 to a language name. (This is the default if fn is omitted.)
- iso_639_name_to_code – convert the language name in param 1 to an ISO 639 code
- iso_639_code_exists – return true if the value in param 1 is an ISO 639 code, otherwise empty
- iso_639_name_exists – return true if the value in param 1 is an ISO 639 language name, otherwise empty
- iso_639 – try to convert the value in param 1 from a language name to an ISO 639 code, and if that fails then try the other way (code to language)
(For more values of |fn=, see § Additional function values below).
|link=yes – if a language name is returned, links it to the Wikipedia article about the language (optional, default=no)
|label=any string – if a language name is returned, and linked with |link=yes, then you can alter the link text by setting this param
|hide_err=yes – blocks the error message returned upon failure of any of the three conversion functions ( iso_639_code_to_name, iso_639_name_to_code, iso_639 ) (optional; default=no)

Additional function values

The following function values are also available for parameter |fn=:

iso_639_code_1_to_name – same as iso_639_code_to_name except constrained to the ISO 639-1 data table
iso_639_code_2_to_name – same as iso_639_code_to_name except constrained to the ISO 639-2 data table
iso_639_code_2B_to_name – same as iso_639_code_to_name except constrained to the ISO 639-2B data table
iso_639_code_3_to_name – same as iso_639_code_to_name except constrained to the ISO 639-3 data table
iso_639_code_5_to_name – same as iso_639_code_to_name except constrained to the ISO 639-5 data table

Language names and codes

For a list of language names and ISO-639 codes, see:

Examples

One parameter

{{ISO 639 name|en}} → English
{{ISO 639 name|fr}} → French

With |fn=iso_639_name_to_code

{{ISO 639 name|English|fn=iso_639_name_to_code}} → en
{{ISO 639 name|French|fn=iso_639_name_to_code}} → fr

Notes

The {{ISO 639 name}} template will trim extraneous IETF language tags to just the ISO 639 code. E.g.: Sanskrit in Latin script, which IETF language tag is sa-Latn, renders as:

{{ISO 639 name|sa-Latn}} → Sanskrit error: sa-Latn is an IETF tag (help)

The error message can be suppressed with |hide-err=yes:

{{ISO 639 name|sa-Latn|hide-err=yes}} → Sanskrit

The rendered language name can be linked to the appropriate language article with |link=yes:

{{ISO 639 name|sa-Latn|hide-err=yes|link=yes}} → Sanskrit

When linking, an alternate link label can be provided with |label=<label text>:

{{ISO 639 name|sa-Latn|hide-err=yes|link=yes|label=sa-Latn}} → sa-Latn

The {{ISO 639 name link}} template is the same as {{ISO 639 name}} except that it presets |link=yes.

Both of these templates can be safely substituted.

Error messages

This template produces error messages. These messages are:

<code> is an IETF tag – IETF language tags are not ISO 639 language codes. When these tags are encountered, the template attempts to render the correct language and also emits this error message
ISO 639-<part> code is required – where <part> is 1, 2, 3, 5; template was called without the required language code
<code> is not an ISO 639-<part> code – <code> fails simple length validation; 639 part 1, language codes are two characters, for 639 parts 2, 3, and 5, language codes are three characters
<code> not found in ISO 639-<part> list – <code> not found after searching ISO 639-<part> data

The module that does the work for this template has other functionality not supported by this template. See Module:ISO 639 name. Error messages related to that other functionality are:

language name required – module function iso_639_name_to_code() only – this message emitted when a language name is not provided in the {{#invoke:}}
<part> not an ISO 639 part – module functions iso_639_name_to_code() and iso_639() only – this message emitted when <part> is not one of 1, 2, 3, or 5
language code or name required – module function iso_639() only – this message emitted when a language name or a language code is not provided in the {{#invoke:}}
