Module:Lang/data/iana languages/make/doc

This is a crude tool that reads a local copy of an IANA language-subtag-registry file and extracts the information necessary to create the data tables held by:

• Module:Lang/data/iana languages
• Module:Lang/data/iana scripts
• Module:Lang/data/iana regions
• Module:Lang/data/iana variants
• Module:Lang/data/iana suppressed scripts
• Module:Lang/data/ISO 639-1 – not an IANA file per se, but used by Module:ISO 639 name; included here so that -1 is not neglected when the other files are updated

The tool skips records that contain the words: 'Deprecated', 'Preferred-Value', and 'Private use'.

At this writing, the tool extracts only the subtag code and description(s) from language, script, region, and variant records.

Usage

To use this tool:

1. Open a blank sandbox page and paste the following at the top:

   {{#invoke:Language/data/iana languages/make|iana_extract}}

2. Go to the current language-subtag-registry file (or any of the files held by archive.org). Copy the whole (or just as much as you need) and paste it into the sandbox page below the {{#invoke:}}.
3. Click Show preview
4. Wait
5. Copy result

There is some crude error checking that will insert an error message in the output. No guarantees that such messaging will be helpful. Search for the word 'error' in the tool's output.
