ഘടകം:Mapframe
ദൃശ്യരൂപം
This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected. |
On English Wikipedia, this module is called by {{Maplink}}
, see that template's documentation for usage instructions.
Usage
[തിരുത്തുക]- Standard usage
- Just use {{Maplink}}, which passes its parameters to this module's main function.
- From another module
-
- Import this module, e.g.
local mf = require('Module:Mapframe')
- Pass a table of parameter names/values to the _main function. See {{Maplink}} documentation for parameter names and descriptions. E.g.
local mapframe = mf._main(parameters)
- Preprocess _main's output before returning it, e.g.
return frame:preprocess(mapframe)
- Import this module, e.g.
Set up on another wiki

symbols with local values (when necessary)
- Edit the top bits of the module, between the comments
- Add documentation
- to the template (e.g. by translating Template:Maplink/doc, adjusting as necessary per any localisations made in the previous step)
- to the module (please transfer/translate these instructions so that wikimedians who read your wiki but not the English Wikipedia can also set up the module and template on another wiki).
