PageTree – Module for parsing and validation of (geo) coordinates.

Functions for templates

feed

Parse single string

1 – coordinate value, to be parsed
latitude – 1 = latitude, else longitude
parameters for direction configuration
parameters for error management

fragments

Process four components

1 – degree
2 – (optional) minutes
3 – (optional) seconds
4 – (optional) direction (N, E, S, W usw.)
latitude – 1 = Breitenkoordinate, sonst Länge
parameters for direction configuration
parameters for error management

failsafe: Version management

The Failsafe interface is heading for version management of globally distributed Lua modules. It enables modules equipped with this interface to

ensure, that a library module required by a template or another module available as local copy does support certain functionality, or complain if not.
administrate global updating and linking of module codes via Wikidata.

The Failsafe interface is present both at template level and for direct Lua access.

The functions in detail are (not all supported yet completely by every library):

Parameter
Value	Result	current
nothing `false`	local version ID	»2022-09-15«
Minimal version	version ID required at least date in ISO format It will be compared whether the current local implementation matches this version or later. empty, if minimal version not achieved	2001-01-01 → »2022-09-15« 2099-01-01 → »«
`wikidata`	version ID of global upstream version ID at Wikidata local, if not found there	»2022-09-15«
`item`	ID of the Wikidata item empty if not defined	`Q113956219`
`~`	Corresponding version ID locally and registered at Wikidata empty, if up to date version ID at Wikidata, if not equal	»«
`@`	Is the current (module) page linked correctly with Wikidata item? empty, if linked to the item which is supposed Iitem ID, if not
The return value is in template programming empty or under Lua `false`, otherwis a non-empty string as described.

Functions for Lua modules (API)

Some functions described above can be used by other modules:

local lucky, CoordParse = pcall( require, "Module:CoordParse" )
if type( CoordParse ) == "table" then
    CoordParse = CoordParse()
else
    -- failure; CoordParse is the error message
    return "<span class='error'>" .. CoordParse .. "</span>"
end
