Metanorma: Aequitate Verum


Metanorma supports a subset of HTML form elements, encoded using Asciidoctor macros [added in]. In PDF and Word output, these elements are rendered with simple fallbacks.

  • A form is entered as an open block or example block with style parameter [form], and with optional parameters id, name, action, and [added in] class.

  • An input element is entered as the macro input:type:[attributes], where type is the input type attribute, and attributes are the remaining supported attributes (id name value disabled readonly checked maxlength minlength), as comma-delimited name=value expressions. The supported types of input are button checkbox date file password radio submit text.

  • A label element is entered as the macro label:for:[text], where for is the value of the label for attribute (i.e. the id attribute of the element it references), and text is the textual content of the label.

  • A select element is entered as the macro select:[attributes], where attributes are the supported select attributes (id name size disabled multiple value). The select element is followed by one or more option:[text,attributes], where 'text` is the display text for the option, and attributes are the supported option attributes (disabled value). For consistency with input, the select/@value is used to indicate a preselected value, instead of option/@selected.

  • A textarea element is entered as the macro textarea:[attributes], where attributes are the supported textarea attributes (id name rows cols value). For consistency with input, the textarea/@value is used to indicate a prepopulated value, instead of text content for the textarea.

The following is an illustration of a Metanorma encoding of a form, and the HTML that it generates:

label:fname[First name:] +
input:text[id=fname,name=fname] +
label:lname[Last name:] +
input:text[id=lname,name=lname] +
label:pwd[Password:] +
input:password[id=pwd,name=pwd] +
label:male[Male] +
label:female[Female] +
label:other[Other] +
label:vehicle1[I have a bike] +
label:vehicle2[I have a car] +
label:vehicle3[I have a boat] +
input:date[id=birthday,name=birthday] +
label:myfile[Select a file:]
input:file[id=myfile,name=myfile] +
label:cars[Select a car:] +
textarea:[id=t1,name=message,rows=10,cols=30,value="The cat was playing in the garden."]
input:button[value="Click Me!"]
