Help:TemplateData/nl

 is een extensie voor het opslaan van informatie en parameters geassocieerd met een wikitext sjabloon, het maakt het beschikbaar voor het bewerken met een nterface die het kan tonen in een sjablooneditor -- dat helpt gebruikers bij het toevoegen en bewerken van sjablonen op pagina's.

In april 2019 is de TemplateData functionaliteit deel van de standaard gebruikerservaring voor alle gebruikers op alle Wikimedia wiki's bij het toevoegen van een sjabloon, ook voor anonieme gebruikers. Zowel de standaard source als de visual editor gebruiken het, net zoals veel script, hulpmiddelen en gadgets. Als u deze functionaliteit op uw eigen wiki wilt gebruiken, installeer dan.

Het toevoegen van TemplateData aan een sjabloon om deze extensie te gebruiken heeft het toevoegen van een klein stukje eenvoudige code  JSON nodig (hieronder uitgelegd) in de documentatiepagina van het sjabloon. U kunt dit handmatig doen of met de TemplateData editor, een grafische gebruikersinterface die u kunt benaderen via de pagina's ""/"" van het sjabloon op wiki's waar de extensie TemplateData is geïnstalleerd. Het JSON bevat een lijst met de parameters van het sjabloon en informatie over die parameters en het template zelf (details hieronder).

Als een gebruiker een sjabloon toevoegt op een pagina dan zal een sjabloon dat TemplateData bevat zal deze informatie tonen in de gebruikersinterface. Soms zal het het gedrag van de editor zich aanpassen wanneer u het gebruikt voor het bewerken of het invoegen van het sjabloon. Het maakt het gemakkelijker voor gebruikers om de stappen uit te voeren die nodig zijn voor het toevoegen van een bepaald sjabloon.

Geschiedenis
TemplateData is oorspronkelijk in 2013 ontwikkeld voor, dat was in die tijd in MediaWiki is de testfase. VisualEditor is de belangrijkste visuele interface voor bewerkingen in Wikimedia wiki's, door TemplateData is de interface krachtiger bij het toevoegen van sjablonen. Het is direct officieel door VisualEditor ondersteund. Bij de uitrol van VisualEditor in verschillende grote Wikimedia wiki's als standaardfunctie in de periode 2013 - 2016, maakte TemplateData daar deel van uit.

In december 2016 is de VisualEditor interface beschikbaar gemaakt voor het bewerken van source als een betafunctie. Dit was een voorwaarde bij de. Dit bracht voor het eerst de functies van TemplateData naar het bewerken van de bron.

In maart 2018 heeft Sam Wilson ontwikkelt, een GUI sjablooneditor extensie voor de standaard Wikimedia source editor,  (ook bekend als de 2010 wikitext editor), ontworpen voor het vereenvoudigen van het toevoegen van sjablonen door gebruik te maken van informatie uit TemplateData. In april 2019 is TemplateWizard een standaardonderdeel van de 2010 wikitext editor gemaakt op alle Wikimedia wiki's. Dit betekent dat TemplateData toen een standaardonderdeel is van zowel de visual editor als de source editor op Wikimedia wiki's.



TemplateData toevoegen en bewerken
Om TemplateData toe te voegen of te wijzigen, ga eerst naar een sjabloonpagina, dus iets met "/Template:Templatename".



De huidige status controleren
Kijk eerst of het sjabloon een subpagina documentatie heeft. Controleer dan of het sjabloon al TemplateData bevat en of dat dan op de sjabloonpagina staat of op de subpagina documentatie.



Documentatie subpagina's
Er zijn twee manieren waarop sjablonen op de meeste Wikimedia wiki's hun gebruiksaanwijzingen en andere informatie opslaan die niet toegevoegd moeten het sjabloon zelf, zoals categorieën waar het sjabloon in zou moeten zitten:


 * De meeste sjablonen houden gebruiksaanwijzingen en andere gegevens die niet bij de sjabloonpagina zelf behoren op een subpagina documentatie: "/Template:Templatename/doc". Op dergelijke pagina's, transcludes het sjabloon {{}} alle /doc pagina inhoud op de sjabloonpagina, hierdoor is de broncode van het sjabloon veel duidelijker.
 * Bij sjablonen met documentatie subpagina's wordt de kop "Test Template Info-Icon - Version (2).svg Template documentation" gevolgd door links als [view], [edit], [history] en [purge].


 * Een paar sjabloonpagina's hebben die informatie op de sjabloon hoofdpagina staan. U kunt het op die pagina's vinden door te zoeken naar  tussen  tags.

De weergave kan per wiki verschillen. Een hoofdpagina van een sjabloon kan heel soms toch nog documentatie bevatten ook al heeft u al het voorgaande gecontroleerd. Een gebruiker kan een aangepaste pagina-kop /doc hebben toegevoegd tussen " " en " " en daarna inhoud na " " hebben toegevoegd.

U kunt ook kijken naar een opmerking onderaan de pagina, die ongeveer het volgende is: "The above documentation is transcluded from Template:Templatename/doc".



Sjablonen zonder documentatie subpagina's
Als het sjabloon geen documentatie subpagina heeft, maak die dan aan en verplaats de sjabloon documentatie daarheen (of met een placeholder). U kunt dan TemplateData toevoegen aan de subpagina documentatie.



Subpagina aanmaken en documentatie verplaatsen
Om de subpagina documentatie aan te maken, klik op ""/"" op de hoofdpagina van het sjabloon; zoek naar de tags tags en de inhoud (meestal onderaan).

Het is iets als dit:

U kunt ook zien dat het al TemplateData bevat. Als dat zo is, dan is het iets als dit:

Selecteer alles tussen " " en "" en verplaats het in je klembord of sla het even ergens neer. Verwijder " ", dan blijft over:

Sla de sjabloonpagina op.

Om nu de nieuwe subpagina aan te maken, ga naar je adresbalk van je browser en voeg /doc toe aan het einde van de URL. Druk op Enter, kies dan de optie om een nieuwe pagina aan te maken.

If this wiki has a {{}} notice template, add it at the top of the new page. You may also wish to add other templates, such as a {{}} or {{}} link (if supported by the wiki in question). See m:Help:Template documentation for more info.

Insert the text you cut or saved in the previous text (beneath the notice template, if applicable).

Wrap any categories in tags so that they apply only to the template's main page:

Many wikis have a  template. Use this template here if it's likely that the template you're editing exists in a sandbox version (located at "Template:Templatename/sandbox") in order to prevent the categories from applying to the sandbox page:

Finally, publish the page.

You can now add and edit the TemplateData on the documentation subpage using the instructions described in #Methods.



TemplateData toevoegen of bewerken op de hoofdpagina van het sjabloon
If you can't create the /doc page, you can add and edit TemplateData on the template's main page by following the instructions in #Methods.

If a template has a documentation subpage, check both the main page and the documentation subpage for the presence of TemplateData (the tag followed by an array inside curly brackets:  ).

Alternatively, the TemplateData extension can perform this check for you. Click "" or "" on either page. If the template already has TemplateData on either page, you will see a yellow notice at the top of the page saying either:



or

If the template has TemplateData on its documentation subpage

If the template has TemplateData on its documentation subpage, this is the page you should edit. You can do this by clicking the "[edit]" located after the heading " Template documentation" (or similar), or, if you are already on the /doc page, by clicking "" or "" at the top. Follow the guidance at #Methods to add or edit the TemplateData.

If the template has TemplateData on its main page

If the template has TemplateData on its main page, you once again have two options:


 * You can either move to its documentation subpage. This is the preferred option.


 * Or, you can edit it on the main template page.

Moving TemplateData to the documentation subpage

To do this, click ""/"" on the main template page, and look for the tags, enclosed within  tags. It should look something like this:

Cut only the tags and their contents out of the code, then save the page.

Next, edit the documentation subpage by clicking the "[edit]" located after the heading " Template documentation" (or similar).

Type a heading, like "TemplateData", then beneath it paste the TemplateData.

You can now edit the TemplateData based on the guidance at #Methods.

Editing TemplateData on the main template page

If you do not wish to move the TemplateData to the /doc page, you can edit it on the main template page. See #Methods for how to edit TemplateData.

If the template does not yet have TemplateData but has a doc subpage

If the template does not yet have TemplateData, you should add it to the documentation subpage.

Do this by clicking the "[edit]" located after the heading " Template documentation" (or similar), or, if you are already on the /doc page, by clicking "" or "" at the top. Type a heading, like "TemplateData", then add it beneath this heading. The section #Methods explains how to add TemplateData.

Methoden


TemplateData bewerkingsmethode
This is a simple way to add or edit TemplateData, recommended for less experienced users.

The TemplateData editor is a graphical user interface for adding and editing TemplateData. It is part of the TemplateData extension, available on any template's page (or documentation subpage) by clicking "" or "".

After clicking "" or "", you will see a button above the editing area and page title that says "".

|453px

Clicking this button will take you to the TemplateData Editor. If the page you are on already contains TemplateData, it will automatically appear here.

600px| The TemplateData editing tool, on a page with no TemplateData.

Features in the above window:


 * The top item chooses the language of the interface text. It allows you to enter text content in multiple languages, displayed to users based on their settings in Preferences, not based on the wiki's language; different wikis have entirely different template databases. If no language TemplateData exists, the interface will only offer users the wiki's own language, but users can click "" to add more inputs. The language code is displayed in brackets next to the parameters to which it can be applied, such as descriptions and labels.
 * The next item is the template description. This is the description of the template as a whole; it's shown to users in numerous places in the template editors while adding a template. This parameter and its effects are outlined here.
 * The third item controls the wikitext formatting of the template. This parameter determines how the wikitext will be laid out when the user clicks "", the two main types being  (on one line) and   (on new lines). This parameter and its effects are outlined here.
 * If the user chooses "", they can enter wikitext under "" according to rules outlined here, in order to create a custom layout for the template when the user clicks "".


 * The fourth item configures a template's parameters. If parameters have already been defined in TemplateData, this area displays them in a list. If the template's source code specifies parameters for which no TemplateData exists, you may see a button labeled "". The editor extracts these suggestions from the template's source code by looking for  or  . Clicking "" will add these parameters using their names as defined in the source code. A green notice will also appear at the top, for example, "".
 * At the bottom of the window you see an "" button. This allows you to add a parameter manually with a custom name.

Continue to the next step by clicking any one of the parameters in the list. This will allow you to edit that parameter's info.

All of these features and their effects are outlined in the section #Within a parameter's name.

When finished, click "". This will automatically insert the TemplateData at the bottom of the page before the tag; or, if already present, it will be updated with the new information without changing its position. The TemplateData text will also be selected when you click "".

The TemplateData editor creates a  parameter at the bottom of the TemplateData (or updates it if it already exists). contains the current TemplateData parameters in the order in which they were displayed by the TemplateData editor. You can change the  by dragging the parameters up and down in the TemplateData editor using the three horizontal bars on the left. and its effects are described here.

After this, click "" to save your revision of the page.



Handmatige methode
You can also add or edit TemplateData manually. TemplateData is written in JSON, but you do not need to learn JSON to learn how to create TemplateData. TemplateData follows a few very simple rules and accepts only a few dozen possible predefined parameters and values, typically following a  format.

Adding TemplateData manually

Considerations:


 * If you're adding TemplateData on a template's documentation subpage (recommended), you may add it anywhere on the page; check to see if your language's Wikipedia has a preferred location for it. For example, on the English Wikipedia, TemplateData is typically near the bottom of the documentation page; on the German Wikipedia, it is typically at the top.
 * If you're adding TemplateData on a template's main page (not recommended; see #Prior checks), you must make sure to place it inside the  tags.

Click "" or "" on the respective page, then move to the place in the page where you intend to add TemplateData and write a heading: "TemplateData".

Many wikis have a TemplateData header template that adds a short notice regarding TemplateData. If your wiki does, add it after the heading.

To start adding TemplateData, type an opening and closing tag and a pair of curly brackets on new lines, with an empty line between them:

Next, add an indent on the empty line between the two curly brackets, and start adding parameters. Details for the parameters can be found at #TemplateData parameters. Most are optional; some are highly recommended.

Parameters can be in any order, but what follows is the order that best conforms to TemplateData documentation and makes the content easiest to use for editors:

Make sure the parameters, for example, in the  object, remain inside that object; otherwise you will trigger an "" error when you try to save.

 Example 

Here is some example TemplateData for a hypothetical cleanup template. Such a template would display a notice and place the page into a dated category based on the month and year entered. The notice might also contain a link to a talk page section. The TemplateData would look something like this:

The corresponding TemplateData documentation would display as follows:

{	"description": "Use this template to indicate that an article is in need of cleanup.", "format": "inline", "params": { "date": { "label": "Month and year", "description": "The month and year that the template was added", "type": "string", "autovalue": " ", "example": "January 2013", "suggested": true },		"reason": { "aliases": ["1"], "label": "Reason", "description": "The reason the article is in need of cleanup", "type": "string" },		"talk": { "aliases": ["talksection"], "label": "Talk page section", "description": "The section of the talk page containing relevant discussion", "type": "string" }	},	"paramOrder": [ "date", "reason", "talk" ] }

TemplateData parameters
All available TemplateData parameters are listed below with a description and example. They are also listed in more technical detail at Extension:TemplateData#Format.



Binnen parameters


Binnen de naam van een parameter
Note: if neither,   nor   are set as   for a parameter, its status will show as   in the TemplateData documentation.

Once you're done, hit "". If you've made errors, it will not let you save (which is disruptive but means you can't break anything). Should you run into errors, explain on the feedback page what you were trying to do, and we will be happy to help.

Note that if you are abusing a hack template to dynamically generate TemplateData, it cannot be checked for errors before saving.

Note that each item of information is enclosed in quotation marks (except for  and  ) and separated from the next bit by a comma (unless it's the last one).

Type parameter
The  parameter is meant to signal to a template editor the nature of a parameter's value. In some cases, template editors have been programmed to modify the user interface for a certain parameter according to this TemplateData value, such as to only allow the user to enter valid values that match the specified type. This parameter does not have any functional effect on the template parameter or its value; it merely controls how template editors see and treat the parameter in editing mode.

How to use

It is used by adding the  parameter, followed by a colon and a space, then adding any of the values listed in the table below in quotation marks.

Example:

Effects

As of February 2020, only 5 of the 13 type values have visible effects in VisualEditor and the 2017 wikitext editor, while 8 have visible effects in TemplateWizard.

The effects of certain values are likely to change as the template editors get updates to support them. One such effort for VisualEditor and the 2017 wikitext editor is tracked in the Phabricator task T55613. A similar effort to get TemplateWizard to support the boolean value is tracked in T200664.

The currently known effects are listed as follows.

Custom formats
When editing the  value, you create custom formats by inputting a set of wikitext symbols using some predefined rules.


 * - start of the template
 * - content (e.g., string, integer or parameter). This underscore serves to indicate the minimum length of a value in characters and can be repeated, like . If this length is not reached, it fills the remaining characters with spaces. This can be used to align all equals signs to a specific position after a parameter (if used with   for new lines).
 * - pipe (separates parameters)
 * - equals sign (precedes the value of a parameter)
 * or pressing the enter key - new line (this will display as  in the entry field)
 * - space (can be used with  to indent new lines)
 * - end of the template

The wikitext should at least meet the minimum of, otherwise there will be an invalid format string error.

Blank boilerplate
You can copy the blank boilerplate below to add new TemplateData to a template. Only the most common tags are included.

Fouten


/ Slecht JSON formaat
These errors occur when saving TemplateData, usually manually edited, with invalid JSON code (duplicate keys/parameters, trailing or missing commas, etc.) in VisualEditor or the 2017 wikitext editor.

"" appears in VisualEditor and the 2017 wikitext editor; "Bad JSON format" appears when editing in the TemplateData GUI editor.

These errors can be difficult to detect and come in too many forms to list. The best way to avoid them is to edit template data exclusively with the TemplateData editor; the best way to detect them once they've occurred is to use an external JSON validator, such as JSONLint, which will highlight errors and aid in fixing them.

The 2010 wikitext editor does not check for invalid JSON thanks to an old, unfixed bug. Pages that contain invalid JSON may throw alarming "" messages. To fix these errors, your best bet is to use a JSON validator (see above).

Required property "paramOrder(number)" not found.
This error occurs if you state a parameter in  that is not stated in. The number in the square brackets refers to the parameter in  that is missing. It refers to its order in the sequence, but it is one less than its actual position, since  is an array; 0 is the first one, 1 is the second, etc.

To fix this, make sure all parameters stated in  are listed in. Alternatively, you can remove the  object to remove this error.

Invalid value for property "paramOrder(number)".
This error occurs if you state a parameter in  that is not stated in. The number in the square brackets refers to the parameter in  that shouldn't be there. It refers to its order in the sequence, but it is one less than its actual position, since  is an array; 0 is the first one, 1 is the second, etc.

To fix this, make sure all parameters stated in  are listed in. Alternatively, you can remove the  object to remove this error.

Property "params.parametername.required" is expected to be of type "boolean".
This error occurs if you put quotation marks around the value of either  or.

These are boolean values, not strings, therefore they require no quotation marks. To fix this, remove any quotation marks around the values  or   for these parameters.

Property "format" is expected to be ...
If the  parameter exists but its value is not ,   or a valid format string, you will see the error message "".

To fix this, make sure the value after  equals   or   and that there no spelling mistakes. Alternatively, if it's wikitext, make sure it contains a minimum of  and that there are no mistakes in the syntax that would normally cause a template to fail, such as duplicate equals signs or missing/duplicate curly brackets; see the section #Custom formats for the syntax for custom formats. Alternatively, you can remove the  parameter to remove this error.

Unexpected property "parametername".
This error occurs if you state a parameter that does not exist in TemplateData. This is probably due to spelling mistakes.

It also occurs if you state a parameter in any TemplateData object that is not a parameter of that object. This may be due to spelling mistakes, or you may have written the parameter of one TemplateData object under another object that it doesn't belong to.

For example, you might have written the parameter  under the root TemplateData object instead of inside  :

Alternatively, if the unexpected parameter is under a template parameter inside, you'll see its name after "params.parametername." in the error.

To fix this, make sure there aren't any spelling mistakes in the parameter names, and make sure your parameters are in their correct location. Additionally, make sure you don't state any parameters that don't exist for a TemplateData object. You can check which parameters exist for an object in the section #TemplateData parameters.

Required property "params" not found.
This error occurs if there is no  object in the TemplateData. This is a necessary object, as it contains all the details of each parameter, so to fix this error, make sure it's added and that there are no spelling mistakes. See the section above on how to add the  parameter.



Beperkingen en feedback

 *  Missing features  – TemplateData is an example of a tool that was made available with few features, in hope that users would help to guide development of features that they desired. If you'd like to request new features for TemplateData, please let us know.
 *  Delays in showing in templates  – After adding TemplateData to a template, the metadata should be visible immediately when the template is opened in the visual editor. However, it is possible that it will take several hours before the metadata will show. You can force an update by making a null edit to the template page itself (not the documentation subpage). To perform a null edit, open the template page for editing, and save the page without making any change and without adding any edit summary.
 *  Current issues  – A list of current bugs and feature requests is available in the Wikimedia bug tracker.
