Usage
beccè'- Standard usage
- Just use {{Maplink}}, which passes its parameters to this module's main function as default.
- If a page has a rendering time by Lua of between 5 seconds and 10 seconds using {{Maplink}} the use of the direct module call by syntax like:
{{#tag:mapframe|[raw GeoJSON]|frameless=[1 for frame]|align=[left/right/center]|text=[caption]|width=[in px]|height=[in px]|latitude=[decimal degrees]|longitude=[decimal degrees]|zoom=[zoom factor]}}saves Lua over-head. An example of this substitution is at https://en.wikipedia.org/w/index.php?diff=970846012. Such code minimises the chances of hitting the ten second Lua timeout if the back-end servers are busy.
- If a page has a rendering time by Lua of between 5 seconds and 10 seconds using {{Maplink}} the use of the direct module call by syntax like:
- 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
beccè'- Create template and module:
- Import this module and its template to that wiki (or copy the code over, giving attribution in the edit summary). Optionally, give them a name that makes sense in that wiki's language
- On Wikidata, add them to the items Modul:Mapframe (Q52554979) and Templat:Maplink (Q27882107)
- Localise the module
- Edit the top bits of the module, between the comments
-- ##### Localisation (L10n) settings #####and-- #### End of L10n settings ####, replacing values between""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).
