Examples

Examples of incorrect code for this rule:

Non-block form (> 80 characters):

{{employee-details firstName=firstName lastName=lastName age=age avatarUrl=avatarUrl}}

Block form (> 80 characters):

  firstName=firstName lastName=lastName age=age avatarUrl=avatarUrl
  as |employee|
}}
  {{employee.fullName}}
{{/employee-details}}

HTML element (> 80 characters):

<input disabled id='firstName' value={{firstName}} class='input-field first-name' type='text' />

Examples of correct code for this rule:

Non-block form (attributes on separate lines):

{{employee-details firstName=firstName lastName=lastName age=age avatarUrl=avatarUrl}}

Block form (attributes on separate lines):

{{#employee-details
  firstName=firstName lastName=lastName age=age avatarUrl=avatarUrl
  as |employee|
}}
  {{employee.fullName}}
{{/employee-details}}

HTML element (attributes on separate lines):

<input disabled id='firstName' value={{firstName}} class='input-field first-name' type='text' />

Short invocations (< 80 characters) are allowed on a single line:

{{employee-details firstName=firstName lastName=lastName}}
