Wiktionary:Todo/Lists/Entries with missing headword lines/description

Technically speaking, the list is generated in two phases.

In the first phase, the script fetches a list of pages which are not in a Pages with n entries or LANG entries that don't exist category. These pages are identified as having no headword line at all.

In the second phase, the script:

1. calculates the number of distinct languages covered by a page's "LANG lemmas", "LANG non-lemma forms", "LANG alternative forms" and "LANG entries that don't exist" categories,
2. checks whether this number is consistent with the Pages with n entries category the page is in, and
3. lists the pages where these numbers don't match.

For example, suppose an entry is in the following categories (among others):

Pages with 5 entries, English lemmas, English non-lemma forms, French entries that don't exist, Franco-Provençal alternative forms, Japanese lemmas, Spanish non-lemma forms

This entry would not appear on the list. However, the following page would be included:

Pages with 2 entries, English lemmas, English non-lemma forms

There are 2 entries but only 1 language is represented among the relevant categories.

Exclusions

• Entries marked for speedy deletion are left off the list.
• Due to significant technical complexity with certain Chinese, Japanese and cuneiform entries, pages that are in Category:Chinese lemmas or transclude one of the CJK cross-reference templates ({{zh-see}}, {{ja-see}}, {{ja-see-kango}} or {{ja-gv}}) or the {{cuns}} template are excluded from the second phase of list creation for the time being. They will only appear in the list if they meet the criteria for the first phase.
• Pages with unrecognised parts of speech supplied to {{head}} are also excluded from the second phase. They may be reincluded in the list at a later time.
