Templat:Tracks and uses Wikidata

Catatan: Kode yang merupakan fungsi utama modul (koord) ini secara langsung diuraikan dan/atau dimanipulasi oleh Modul:Location map dan fungsi lain dari modul ini sendiri (coord2text dan coordinsert). Jika struktur output berubah (misalnya, untuk menggunakan tag <mapframe> dan <maplink>), mohon perbarui skrip yang disebutkan di atas juga.

Menggunakan modul dengan coordinsert

Saat menggunakan templat {{Coord}} di dalam templat lain, seperti sebuah kotak info, mungkin ada parameter (seperti type:airport) yang harus ditambahkan secara otomatis. Untuk melakukannya, lakukan sesuatu seperti ini: 

{{#if:{{{coordinates|}}}|{{#invoke:Coordinates|coordinsert|{{{coordinates|}}}|parameter1:value1|parameter2:value2|parameter3:value3…}}|

Jangan menambahkan palang vertikal | lebih banyak dari yang diperlukan.

Menggunakan modul dengan coord2text untuk mengekstrak garis lintang atau garis bujur

Para pengembang yang memelihara kode warisan sebelumnya mungkin perlu mengekstrak garis lintang atau bujur untuk menggunakan parameter dalam kode lain, atau ekspresi matematis. Fungsi "coord2text" dari modul ini dapat digunakan untuk mengekstrak data dari templat {{Coord}}. Untuk mengekstrak garis lintang dari templat Coord, gunakan:

{{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|lat}} →

Untuk mengekstrak garis bujur, gunakan:

{{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|long}} → Lua error in mw.text.lua at line 223: bad argument #1 to 'len' (string expected, got nil).

Extracts a single value from a transclusion of {{Coord}}.
IF THE GEOHACK LINK SYNTAX CHANGES THIS FUNCTION MUST BE MODIFIED.

Usage:

    {{#invoke:Coordinates | coord2text | {{Coord}} | parameter }}

Valid values for the second parameter are: lat (signed integer), long (signed integer), type, scale, dim, region, globe, source

coordinsert

Injects some text into the Geohack link of a transclusion of {{Coord}} (if that text isn't already in the transclusion). Outputs the modified transclusion of {{Coord}}.
IF THE GEOHACK LINK SYNTAX CHANGES THIS FUNCTION MUST BE MODIFIED.

Usage:

    {{#invoke:Coordinates | coordinsert | {{Coord}} | parameter:value | parameter:value | … }}

Do not make Geohack unhappy by inserting something which isn't mentioned in the {{Coord}} documentation.
