Modul:FormatTemplate
 | Ta modul je ocenjen kot alfa. Pripravljen je za urejanje drugih uporabnikov in se lahko uporablja na nekaj straneh, da se ugotovi, ali se pojavijo težave, vendar je treba z njim biti pazljiv. Dobrodošli so predlogi za nove funkcije ali spremembe njihovih vhodnih in izhodnih mehanizmov. |
This module formats a template, indenting each line beginning "|" according to the number of parser functions, templates, links, and parameters it is embedded within.
It still needs proper documentation and hopefully some solution to the problem of making the text re-pastable before I'll call it an alpha.
| Zgornja dokumentacija je vključena iz Modul:FormatTemplate/dok. (uredi | zgodovina) Urejevalci lahko preizkušate ta modul v peskovniku (ustvari | mirror) in testnihprimerih (ustvari). Prosimo, da dodate kategorije v /dok podstran. Podstrani te predloge. |
---- This module is intended to format templates to make them readable.
---- It should work by recognizing every beginning that ''should'' not be intermingled: [[, {{, {{#, {{{
---- It will count how many levels deep you've gone.
---- It will add 4 times that many spaces before each pipe | in a non-[[ element, removing any now present
---- It will label the beginning and end with a color specific to the type of element even when it can't indent
---- It will return everything in a nowiki wrapper (excluding the color formatting)
