TemplateData é uma extensão usada para armazenar informações sobre uma predefinição de wikitexto e seus parâmetros, de forma que o editor visual possa as recuperar e exibir esta informação em seu editor de predefinições, facilitando a edição de páginas que usam aquela predefinição.

Desde abril de 2019, TemplateData é parte da experiência padrão do usuário para todos os usuários nas wikis da Wikimedia quando eles adicionam um template, incluindo usuários não-registrados. Tanto a fonte padrão quanto os editores visuais incorporam ela de alguma maneira. Ela também é usada em outros lugares como em scripts, ferramentas e gadgets. Se tem a sua própria wiki, então, terá de instalar Extensão:Dados de Modelo.

Adicionando TemplateData a um template consiste essencialmente em inserir um pequeno bloco de código JSON (explicado abaixo) no template de documentação da página. Há duas maneiras principais de fazer isso, manualmente ou usando o editor TemplateData, um usuário de interface gráfica localizado nas páginas "Editar"/"Editar Código-fonte" de templates da wikis com o TemplateData instalado. JSON contém uma lista de parâmetros com informações sobre cada parâmetro do template bem como o template como um todo. Eles estão sublinhados abaixo.

Uma vez que um template tenha TemplateData, esta informação aparecerá na interface do usuário quando um usuário adicionar o template, às vezes no lugar da informação original ou como informação adicional. Em alguns casos, isso pode mudar a maneira como o editor se comporta quando editando ou inserindo o template. Isso pode facilitar muito para usuários identificarem o que eles precisam fazer com o template ao adicioná-lo.

História

TemplateData foi originalmente desenvolvido no início de 2013 com VisualEditor em mente, que foi na época do estágio de testes da MediaWiki na época. Visualditor é a interface visual de edição principal para as wikis da Wikimedia, e TemplateData permitiu que houvesse uma interface mais útil ao adicionar templates. Ela foi imediatamente apoiada oficialmente pela VisualEditor Como VisualEditor foi lançado nas várias principais wikis da Wikimedia como um recurso padrão de 2013 a 2016, TemplateData se tornou parte disso também.

Em março de 2018, Sam Wilson desenvolveu TemplateWizard , uma extensão de edição de template GUI para o padrão de edição de código-fonte da Wikimedia, WikiEditor (também conhecido como o editor de wikitexto de 2010), projetado para fazer o processo de edição de templates mais fácil usando informações do TemplateData. Em abril de 2019, TemplateWizard foi feito parte padrão do editor de wikitexto de 2010 em todas as wikis da Wikimedia. Isso significava que TemplateData era agora parte padrão de ambos o editor visual e o editor de código-fonte das wikis da Wikimedia.

Editor TemplateData

O editor do TemplateData é uma ferramenta incorporada na extensão TemplateData para adicionar e editar "Dados de Modelagem" usando uma interface gráfica para usuários.

Para acessar a ferramenta, vá em qualquer página de modelo (ou subpágina de documentação) e clique em "Editar" ou "Editar código-fonte". Depois disso, você verá um botão acima da área de edição que diz "Administrar TemplateData".

Clique nesse botão para entrar na interface gráfica de edição da TemplateData.

O editor permite-lhe adicionar parâmetros de predefinições e definir os atributos mais comuns. Se a página que você editou já contém um bloco de TemplateData, então a informação já documentada será mostrada automaticamente quando você abrir a página correta no editor de TemplateData. Na primeira caixa, pode adicionar ou atualizar uma breve descrição da predefinição em texto simples. Depois, você pode usar os botões Adicionar parâmetros sugeridos e Adicionar parâmetro para documentar os nomes e atributos dos parâmetros que a predefinição usa.

Você pode listar o nome do parâmetro, seus nomes alternativos, seu rótulo e a descrição que será exibida aos usuários. Você pode fornecer também um exemplo de como usar o parâmetro. O único campo obrigatório é Nome (o primeiro campo de cada linha), em que você pode guardar o nome exato do parâmetro, sensível a letras maiúsculas e minúsculas. No menu suspenso Tipo você poderá escolher o tipo de conteúdo que o parâmetro deverá receber, como uma string (para respostas em texto sem formatação), uma página (para ligações a outras páginas), ou datas. Caso a predefinição possa gerar um erro se o parâmetro for deixado em branco, marque como Obrigatório. Caso o parâmetro seja usado frequentemente ou seja recomendado, marque como Sugerido. O botão Remover informação do parâmetro deletará a entrada do parâmetro do TemplateData.

Quando você terminar com a documentação de cada parâmetro, clique em Aplicar para inserir o TemplateData pré-formatado dentro da caixa de edição aberta. Você deve ainda salvar a página, usando o botão Salvar abaixo da janela de edição.

Atenção: O editor do TemplateData posicionará o TemplateData ou na página da predefinição ou na subpágina da documentação. Você poderá determinar onde o TemplateData será adicionado abrindo (editando) a página em que você deseja posicioná-lo. Todavia, se múltiplos blocos de TemplateData são posicionados na mesma predefinição, então apenas um desses blocos será utilizado. Caso já haja TemplateData numa página, então você deverá editar a página em que o TemplateData foi anteriormente colocado para evitar a criação acidental de múltiplos blocos de TemplateData.

Localização do TemplateData

TemplateData deve estar na página que descreve, ou deve estar transcluído nela. In a template, it shall typically be wrapped into <noinclude> tags. On normal page rendering, it displays autogenerated documentation as shown in #Example.

Estrutura do TemplateData

A estrutura do TemplateData é baseada no padrão JSON. Note que todas as descrições no TemplateData devem estar em texto sem formatação (sem wikitexto, sem links, etc.).

A primeira coisa a fazer é digitar um par de tags <templatedata>, em qualquer lugar da subpágina de documentação da predefinição, assim:

<templatedata>
{
    ...       // O conteúdo TemplateData fica aqui
}
</templatedata>

Isso diz ao programa que tudo que está entre as duas tags é TemplateData, e deve ser usado como referência quando a predefinição for empregada.

Exemplo

The descriptions inside TemplateData follow a standard layout; let's say that you have a template called "Commons" for linking to a Commons category about a topic. It takes one mandatory parameter: the name of the category on Commons. The TemplateData would look something like this:

<templatedata>
{
    "description": "A template for linking to a commons category about an article",
    "params": {
        "1": {
            "label": "Categoria do Commons",
            "description": "A categoria do commons à qual você deseja vincular.",
            "default": "Category:CommonsRoot",
            "type": "string",
            "required": true
        }
    }
}
</templatedata>

Isto seria apresentado, na predefinição, assim:

Um modelo para vincular a uma categoria da commons sobre um artigo

Template parameters

ParameterDescriptionTypeStatus
Categoria do Commons1

A categoria da commons à qual você deseja vincular.

Default
Category:CommonsRoot
Stringrequired

Parâmetro da TemplateData

Each parameter for TemplateData is listed below with a description and example. They are also listed at Extension:TemplateData#Format.

The order of the parameters does not affect functionality, as long as those within, for example, the "params" object are kept within the object.

This information is current as of February 2020 and may change if new parameters are added or the template editing interfaces get updates to treat certain parameters differently or fix certain behaviours.
Parameter Description Example
description

The "description" parameter describes what the template does. It is optional but highly recommended.

Wiki markup will not work in the description. It is strictly a plain text string.

Effects

On the template documentation page, the description will show in plain text below the "Template data for [template name]" subheading.

In all main editors (VisualEditor , the Editor de wikitexto 2017 and the 2010 wikitext editor with TemplateWizard), the description shows in two main instances:

  • below the template name in each search suggestion when the user is searching for a template
  • below the template name in the template editor, while they are adding values to parameters in the template.

In the VisualEditor and 2017 wikitext editor, approximately 50 characters of the description show under each search suggestion, followed by a "...", but the whole description shows in the main template editor window. Both are shown in grey text.

In the 2010 wikitext editor with TemplateWizard, the whole description shows under each search suggestion, in grey text. In the main template editor window, descriptions longer than four lines (about 540 characters) are provided a separate scrollbar, and they are shown in black text.

If not specified

If the description parameter does not exist or is not specified, the text "No description." will be displayed in the TemplateData documentation below the "Template data for [template name]" subheading. Additionally:

  • in VisualEditor and the 2017 wikitext editor, it will behave the same as a template that does not have TemplateData; instead of a description, the following text will display:
"The "Template:Cleanup/sandbox" template doesn't yet have a description, but there might be some information on the template's page."
  • in the 2010 wikitext editor with TemplateWizard, the following text will display where the description would be (though not in search suggestions):
"No description exists for this template."
This is different to the two standard placeholder descriptions when TemplateData doesn't exist:
  • "Due to missing TemplateData, parameters for this template have been auto-generated. Please be aware that they may not be accurate."
  • "No parameters could be determined for this template due to absence of TemplateData documentation. You may insert the template without parameters."
"description": "Um modelo para vincular a uma categoria comum",
format

The "format" parameter describes how the template's wikitext should be laid out. This can be set to the standard formats of "inline" and "block", or the user can input a set of wikitext symbols to create a custom format; these symbols and some examples are listed in the section #Custom formats.

This parameter is not required, but it is recommended. The default behaviour when this parameter does not exist is inline formatting, and no corresponding notice is displayed in the TemplateData documentation below the table heading.

Effects

Inline:

If the parameter is set to "inline", the template will display a corresponding notice about the preference in its TemplateData documentation, below the table heading, "Template parameters":

"[circles and pipes icon] This template prefers inline formatting of parameters."

When inserted, the template will lay its wikitext out on a single line with no white space between elements, like so:

{{Foo|bar=baz|qux=quux}}

Block:

If the parameter is set to "block", the template will display the following preference notice in its TemplateData documentation:

"[stacked blocks and pipes icon] This template prefers block formatting of parameters."

When inserted, the template will distribute its parameters each on a new line, with single spaces between each element, like so:

{{Foo
| bar = baz
| qux = quux
}}

Custom formatting:

Alternatively, if the parameter is set to a custom string of wikitext, as per the rules listed at #Custom formats, the template will display the following preference notice in its TemplateData documentation:

"[cogwheel icon] This template has custom formatting."

When inserted, the template will lay its wikitext out as per the given wikitext.

"format": "inline"
params

The "params" object contains the information for each parameter of the template. It is required, and its parameters can be viewed in the #Within params section.

It should contain the name of each parameter followed by a set of TemplateData sub-parameters listed in #Within the parameter's name.

If there are multiple parameters, separate each parameter object with a comma between each one, after the closing curly bracket (i.e. not after the last one).

"params": {
    "parameter1": {
        ...    //  parameter info
    },      // vírgula aqui
    "parameter2": {
        ...    //  parameter info
    },      // e aqui
    "parameter3": {
        ...    //  parameter info
    }       //  but not here
}
paramOrder

The "paramOrder" object in an optional object that can force the parameters of a template to show in a specific order when added in the template editor.

It is used by adding the parameter "paramOrder", followed by a colon and space, then including the name of each of the template's parameters in speech marks in a desired order, separated by commas, between two square brackets (an array). The parameters do not have to be on new lines (they can be "paramOrder": ["param1","param2","param3"]), but placing them on new lines may aid in legibility. Every parameter mentioned in the TemplateData must be included, or an error will show.

Effects

In VisualEditor and the 2017 wikitext editor, paramOrder forces its order regardless of the status of each parameter.

In the 2010 wikitext editor with TemplateWizard, "required" parameters will always appear at the top, while "suggested" parameters will always appear second, above "optional" ones ("deprecated" parameters won't appear at all; see the description of "deprecated" for more info). paramOrder will only enforce its order within these categories (i.e., all "required" parameters will be in the order specified by "paramOrder", and all "suggested" parameters will be too, but all "suggested" parameters will appear below all "required" parameters).

"paramOrder": [
	"date",
	"reason",
	"talk"
]

Within params

Parameter Description Example
parameter name

The only first-level item of the params object is the name of a parameter of the template.

For example, in a template's source code, if you see {{{date}}}, this is a parameter, and this should be added under "params" with the name "date".

You may also see parameters named {{{1}}} or another number (whose TemplateData name should be, for example, "1"). These parameters behave in such a way that, when a user inserts a template, they can omit their name and the equals sign (i.e., |value| instead of |parametername=value|). Their number indicates which empty parameter they are when multiple empty parameters are used. For example, expect that in

{{example template|value1|value2}}

value1 is the value of parameter {{{1}}}, and value2 is the value of parameter {{{2}}}. Make sure to describe your TemplateData parameters accordingly. Note: a user can still force the use of {{{2}}} without {{{1}}} by simply inserting a parameter named "2" in the template editor or typing "|2=" in wikitext.

Each of these "parameter name" objects should contain all of the information about the parameter, in the form of more parameters. These are listed in the following section, Within the parameter's name.

"1": {     // name of the parameter
    ...    // information about the parameter goes here
}

Within the parameter's name

Parameter Description Example
aliases

The "aliases" parameter is a optional item for when a template parameter has multiple names. You can check this by going into the template's source code and looking for:

{{{parameter1|{{{parameter2}}}}}}, or {{{parameter1|{{{parameter2|}}}}}}

This literally translates to, "Value of parameter1. If parameter1 doesn't exist or have a value, value of parameter2." In the second case, it also means, "If parameter2 doesn't exist or have a value, no value." This means that if the user inserts either of these parameters with a value, they will perform the same function.

To insert the "aliases" parameter, add the text "aliases" followed by a colon and space, then include the name of each of the parameter's aliases in speech marks, separated by commas, between two square brackets (an array).

"aliases": ["1", "talk", "talksection"]
inherits

"inherits" is an optional parameter for when a parameter should inherit all of the TemplateData of another parameter. This can then be overridden by any parameters specified for the inheriting parameter.

To use this parameter, type "inherits" : followed by another template parameter's name, such as "talk" or "1". You can then type another specific setting for the parameter underneath if you wish, like "label" : "A different label". The first parameter will inherit all of the second parameter's properties except this one.

    "params": {
        "tópico1": {
            "label": "Tópico",
            "description": "A topic mentioned on this disambiguation page",
            "type": "string"
        },
        "tópico2": {
            "inherits": "tópico1"
        },
        "tópico3": {
            "inherits": "tópico1",
            "label" : "A different label"
        }
    }
label

The "label" parameter is a human-readable title for the parameter that will be displayed within the template editor. It displays this in place of the parameter's raw name. This parameter is optional but highly recommended.

"label": "Month and year",
description

Within each object named after a parameter, "description" is a description of the parameter, not the template as a whole. This description is shown in a tooltip when the user hovers over the "i" symbol next to the parameter in the template editor. It is optional but highly recommended.

"description": "The month and year that the template was inserted.",
type

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

  • "string" - um conjunto de caracteres, como esta sentença;
  • "number" - um conjunto de dígitos;
  • "boolean" - '0' for false, '1' for true, '' for unknown;
  • "wiki-user-name" - um conjunto de caracteres que representa um nome de usuário;
  • "wiki-page-name" - um conjunto de caracteres que representa um título de página;
  • "wiki-file-name" - um nome de arquivo

Other types include: "unknown", "date", "url", "wiki-template-name", "content", "unbalanced-wikitext", "line"

To see the effects of the type parameter, see the section #Effects of the type parameter.

"type": "string",
default

Occasionally, a template parameter is programmed to have a default value that is used unless you change it. The "default" item is an optional item intended to tell the user what this value is. The value does not have to match the actual default and has no functional effect. You can ignore this parameter if there's no default.

Effects

In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), the "default" text will show as grey text in the input box of any open parameter when it is empty, in the format "Default: default text". Additionally, it will show in plain black text in the parameter description (when the user hovers over the "i" symbol). In VisualEditor and the 2017 wikitext editor, this will be below the parameter description, below "Field is required"/"Field is deprecated", if specified (the 2010 wikitext editor doesn't show this text), and above "example", if specified ("example" does not show in the parameter description in the 2010 wikitext editor). In the 2010 wikitext editor with TemplateWizard, the "default" text shows directly after the parameter description, on the same line, following a space. It shows in the same format as the other editors ("Default: default text").

With other parameters

In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), if "default" is specified, the "example" value will not show in the input box.

"default": "Category:CommonsRoot",
autovalue

You can specify an "autovalue" for a parameter. When a user adds the template to a page, this value will automatically appear in the input box. For example, many cleanup templates are supposed to have the date added; if you set the autovalue for the template's date parameter to be {{subst:CURRENTMONTHNAME}} {{subst:CURRENTYEAR}}, the month and year that the template was added will be filled in automatically.

This parameter does not force the value to always be this value. The user can freely change the value that is automatically inputted into the parameter in the template editor.

With other parameters

In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "autovalue" overrides the visible effects of "url" in VisualEditor and the 2017 wikitext editor. See the description for "type" for more info.

"autovalue": "{{subst:CURRENTMONTHNAME}} {{subst:CURRENTYEAR}}"
example

The "example" value is an optional value intended to display an example input to show how the parameter is used.

Effects

In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), it shows a grey text in the input box of any open parameter when it is empty, in the format "e.g. example text". Additionally, in VisualEditor and the 2017 wikitext editor, it shows the same text in black, non-italic font below the parameter description (and below the "default" text, if specified).

With other parameters

In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "example" will not show in the input box if "default" is specified.

"example": "January 2013",
required

We then have "required", which can be set to either true or false. If you don't specify, it will be assumed to be false.

This specifies whether filling out the parameter is mandatory for that template.

Effects

This status has several effects in VisualEditor and the Editor de wikitexto 2017 :

  • it makes the parameter automatically show up when a user inserts a template;
  • it shows a grey asterisk next to the parameter label;
  • it shows a black asterisk within the input box, on the right;
  • it shows the grey, italic text "Field is required" below the parameter description;
  • it makes the input box glow red if the user clicks away without entering a value;
  • if a user attempts to insert the template without a value in the required parameter, it will show them a prompt, asking if they are sure. If they confirm, it will insert the parameter with a blank value. It will not stop them from inserting the template, though, and it does not result in a visible error by itself (though templates can be programmed to display an error when a required parameter is not filled in).

In the 2010 wikitext editor with TemplateWizard, like in the other editors, it causes the parameter to automatically show up when a user inserts a template, but in this editor the parameter cannot be removed. It also does not display "Field is required" in the parameter description; rather, it lists the parameter on the side under "Required parameters". Other than this, it generally behaves the same as in the other editors, except that the prompt says that the input doesn't "match the expected format".

With other parameters

In VisualEditor and the 2017 wikitext editor, the "deprecated" status does not override the functionality of this parameter, but in the 2010 wikitext editor with TemplateWizard it does. See the description of "deprecated" for more info.

"required": true
suggested

There is "suggested", which can be set to either true or false. If you don't specify, it will be assumed to be false.

This is a status for parameters that are not "required" but are recommended to be high value (but not mandatory) for template users.

Effects

In VisualEditor and the Editor de wikitexto 2017 , it causes the parameter to automatically show up when a user inserts a template. If the parameter has an autovalue set, this will also automatically be in the parameter's input box. It has no other effect and doesn't show any additional text or warnings.

In the <tvar|1>2010 wikitext editor with TemplateWizard, it does not place the parameter in the template automatically but instead causes it to be listed on the side under "Suggested parameters". The user can then click a "+" next to the parameter to add it to the template.

With other parameters

The "required" status overrides the functionality of this status in all main editors (VisualEditor, the 2017 wikitext editor and the 2010 wikitext editor). It also overrides the displayed "suggested" status in TemplateData documentation (it will display "required" if both "required" and "suggested" are set to true).

"suggested": true
deprecated

Finally, there is "deprecated", which can be set to true, false, or a string describing what users should instead do. If you don't specify, it will be assumed to be false.

This is a status for parameters that should not be used any more but still exist for the time being. This could be because uses of the template are being moved from one set of parameters to another.

Effects

The effect of this parameter in VisualEditor and the 2017 wikitext editor is that a grey exclamation mark shows next to the parameter's label when it is inserted, and in the parameter's information tooltip, the grey, italic text "Field is deprecated" is shown below the parameter description. It does not affect the functionality or usability of the parameter or show any additional warnings.

Despite the fact that it can take a string, as of January 2020 none of the main editors (VisualEditor, the 2017 wikitext editor or the 2010 wikitext editor) display the contents of the string anywhere to users. Inputting a string has the same effect as true.

In the 2010 wikitext editor with TemplateWizard, setting this value as true does not allow the parameter to be added or seen.

With other parameters

If you set both this and "suggested" as true, the parameter status will show as "deprecated" in the TemplateData documentation, but in VisualEditor and the 2017 wikitext editor both functionalities will be retained; the parameter will automatically show up when a user inserts a template, but it will have the "deprecated" warnings around it.

If you set both this and "required" as true, the parameter status will show as "deprecated" in the TemplateData documentation, but in VisualEditor and the 2017 wikitext editor it will have the same functionality as only "required"; the parameter will automatically show up when a user inserts a template, and it will have the "required" warnings around it. This is the same for if you set "deprecated", "suggested" and "required" as true.

In the 2010 wikitext editor with TemplateWizard, "deprecated" overrides the parameters "required" and "suggested".

"deprecated": "Please use 'publicationDate' instead."

Note: if neither "required", "suggested" nor "deprecated" are set as true for a parameter, its status will show as "optional" in the TemplateData documentation.

Once you're done, hit "save". 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 true and false) and separated from the next bit by a comma (unless it's the last one).

Effects of the type parameter

The "type" parameter can have multiple different effects or no effect depending on the value and depending on the template editor. Its effects are listed as follows.

"number":

The "number" value is intended for numerical values, including minus values and decimals.

  • In VisualEditor and the 2017 wikitext editor, "number" has no visible effect.
  • In the 2010 wikitext editor with TemplateWizard, "number", causes the input box to display a "+" and "-" button on either side, which raise or lower a number value in the input box, respectively, and the user can only type numbers into the box. The buttons can also lower the number into negatives.

"string":

The "string" value is intended for any string of plain text.

  • In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "string" has no visible effect compared to "unknown".

"line":

The "line" value is intended for content that should be forced to stay on one line.

  • In VisualEditor and the 2017 wikitext editor, "line" prevents a parameter's input box from allowing new lines, which are usually possible in these editors.
  • In the 2010 wikitext editor with TemplateWizard, "line" has no visible effect (input boxes do not allow new lines by default in this editor).

"url":

The https:// value is intended for a URL, with Internet protocol (e.g., "https://") included.

  • In VisualEditor and the 2017 wikitext editor, "url" makes the input box display an external link icon (a square with arrow pointing out of it) in the left hand side of the box and makes the box glow red when the user clicks away without entering a URL value that includes a valid Internet protocol (e.g., "https://", "ftp://" or "//") followed by some text. This second effect is similar to that of the "required" setting, but it does not warn the user if they attempt to insert the template without a valid URL. It also occurs with any status setting (such as "suggested" or "deprecated").
  • In the 2010 wikitext editor with TemplateWizard, "url" has no visible effect.

"wiki-page-name":

The "wiki-page-name" value is intended for a page name on a wiki.

  • In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "wiki-page-name" makes the parameter input box show a suggestion dropdown menu containing a list of pages on the wiki, such as Wikipedia articles, which can be selected. Namespaces can also be defined in the search. Additionally, in VisualEditor and the 2017 wikitext editor, it forces the input box content to stay on one line. It has no other visible effect and doesn't prevent a non-page from being inputted.

"wiki-file-name":

The "wiki-file-name" value is intended for a file name hosted either locally on a wiki or on Wikimedia Commons.

  • In VisualEditor and the 2017 wikitext editor, "wiki-file-name" has no visible effect.
  • In the 2010 wikitext editor with TemplateWizard, "wiki-file-name" makes the parameter input box show a suggestion dropdown menu containing a list of files hosted both locally and on Wikimedia Commons, which can be selected. It also shows the thumbnail of the files. It has no other visible effect and doesn't prevent a non-file from being inputted.

"wiki-template-name":

The "wiki-template-name" value is intended for the name of a template.

  • In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "wiki-template-name" makes the parameter input box show a suggestion dropdown menu containing a list of templates, which can be selected. Additionally, in VisualEditor and the 2017 wikitext editor, it forces the input box content to stay on one line. It has no other visible effect and doesn't prevent a non-template from being inputted.

"wiki-user-name":

The "wiki-user-name" value is intended for a username on a wiki.

  • In all main editors (VisualEditor, 2017 wikitext editor and the 2010 wikitext editor with TemplateWizard), "wiki-user-name" makes the parameter input box show a suggestion dropdown menu containing a list of actual users' names, which can be selected. Additionally, in VisualEditor and the 2017 wikitext editor, it forces the input box content to stay on one line. It has no other visible effect and doesn't prevent a non-username from being inputted.

"content":

The "content" value is intended for wikitext of page content, for example, links, images or text formatting.

  • In VisualEditor and the 2017 wikitext editor, "content" has no visible effect.
  • In the 2010 wikitext editor with TemplateWizard, "content" makes the parameter input box one line taller and allows new lines, which regular input boxes in the 2010 wikitext editor do not.

"unbalanced-wikitext":

The "unbalanced-wikitext" value is intended for wikitext that cannot stand alone, i.e. it lacks an opening or closing tag or refers to other parts of wikitext.

  • In VisualEditor and the 2017 wikitext editor, "unbalanced-wikitext" has no visible effect.
  • In the 2010 wikitext editor with TemplateWizard, "unbalanced-wikitext" makes the parameter input box one line taller and allows new lines, which regular input boxes in the 2010 wikitext editor do not.

With other parameters

  • In VisualEditor and the 2017 wikitext editor, "autovalue" overrides the visible effects of "url" - when both are set, the input box will not contain a URL icon nor glow red when the user clicks away without entering a valid URL.
  • In the 2010 wikitext editor with TemplateWizard, "number" overrides the effects of "autovalue" - the value of "autovalue" will not be automatically placed in the input box if the parameter type is "number".

Formatos personalizados

When editing the "format" 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 \n for new lines).
  • | - pipe (separates parameters)
  • = - equals sign (precedes the value of a parameter)
  • \n or pressing the enter key - new line (this will display as in the entry field)
  • - space (can be used with \n 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.

Examples of formats you can use
Objective Format string Output
Inline formatting {{_|_=_}}
inline
{{Foo|bar=baz|qux=quux}}{{Bar}}
Block formatting {{_\n| _ = _\n}}
block
{{Foo
| bar = baz
| qux = quux
}}{{Bar
}}
No space before the parameter name,

each template on its own line

\n{{_\n|_ = _\n}}\n
{{Foo
|bar = baz
|qux = quux
}}
{{Bar
}}
Indent each parameter {{_\n |_ = _\n}}
{{Foo
 |bar = baz
 |qux = quux
}}{{Bar
}}
Align all parameter names to a given length {{_\n|_______________ = _\n}}\n
{{Foo
|bar             = baz
|qux             = quux
|veryverylongparameter = bat
}}
{{Bar
}}
Pipe characters at the end of the previous line {{_|\n _______________ = _}}
{{Foo|
  bar             = baz|
  qux             = quux}}{{Bar}}
Inline style with more spaces, must be at start of line \n{{_ | _ = _}}
{{Foo | bar = baz | qux = quux}}
{{Bar }}
Template at the start of a line, indent-aligned parameters, pipe beforehand \n{{_ |\n _______________ = _}}
{{Foo |
  bar             = baz |
  qux             = quux}}
{{Bar}}

Blank boilerplate

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

<templatedata>
{
    "description": "",
    "params": {
        "1": {
            "label": "",
            "description": "",
            "type": ""
        },
        "2": {
            "label": "",
            "description": "",
            "type": ""
        }
    }
}
</templatedata>


Errors

Syntax error in JSON / Bad JSON format

This error occurs if you attempt to save TemplateData that has certain types of invalid JSON code, such as duplicate keys (parameters) or trailing/missing commas, in VisualEditor or the 2017 wikitext editor (JavaScript-based editors).

"Syntax error in JSON" shows if you attempt to save such code in VisualEditor or the 2017 wikitext editor, while "Bad JSON format" shows if you attempt to open up such code in the TemplateData GUI editor, on template pages.

This error can come up quite frequently while editing a template's TemplateData. The most common mistakes that cause this error include excess commas (such as trailing commas), missing commas and missing quotation marks.

Examples of trailing commas:
<templatedata>
{
    "description": "",
    "format": "inline",
    "params": {
        "1": {
            "label": "",
            "description": "",
            "type": "", // <-- This comma shouldn't be here.
        }, // <-- This comma shouldn't be here.
    }, // <-- This comma shouldn't be here.
}
</templatedata>
Examples of missing commas:
<templatedata>
{
    "description": "",
    "format": "inline" // <-- A comma should be here.
    "params": {
        "1": {
            "label": "",
            "description": "" // <-- A comma should be here.
            "type": ""
        }
    }
}
</templatedata>
Example of missing quotation marks:
"description": An example description // <-- This text should have quotation marks.

To fix these errors, you can either look for the errors in the code yourself, or you can enter the JSON block into an external JSON validator, such as JSONLint, and it will highlight the problematic commas and keys that should be removed.

Due to a longstanding bug, users using the 2010 wikitext editor are able to save pages that have such invalid JSON (details: tarefa T128029), as the JavaScript parser is less strict and allows invalid JSON.

Required property "paramOrder(number)" not found.

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

"params": {
    "date": { ...
    },
    "reason": { ...
    },
    "talk": { ... // <-- This parameter is not stated in "paramOrder", but it should be.
    }
},
"paramOrder": [
	"date",
	"reason"
]

// Error: Required property "paramOrder[2]" not found.

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

Invalid value for property "paramOrder(number)".

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

"params": {
    "date": { ...
    },
    "talk": { ...
    }
},
"paramOrder": [
	"date",
	"reason", // <-- This parameter is not stated in "params", but it should be.
    "talk"
]

// Error: Invalid value for property "paramOrder[1]".

To fix this, make sure all parameters stated in "paramOrder" are listed in "params".Alternatively, you can remove the "paramOrder" 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 "required" or "suggested".

"suggested": "true" // <-- These quotation marks shouldn't be here.

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

Property "format" is expected to be ...

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

"format": "notinline"

// Error : Property "format" is expected to be "inline", "block", or a valid format string.

To fix this, make sure the value after "format": equals "inline" or "block" 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 "format" parameter to remove this error.

Unexpected property "parametername".

This error occurs if you state a parameter in any 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 object under another object that it doesn't belong to.

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

<templatedata>
{
    "description": "",
    "format": "inline",
    "label": "", // <-- incorrectly placed parameter
    "params": {
        "1": { // ↓ it should be in here
            "description": "",
            "type": ""
        }
    }
}
</templatedata>

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

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

Required property "params" not found.

This error occurs if there is no "params" 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 "params" parameter.
