Config File

The config.json file is an essential component of developing a Quick Design framework. This file contains both meta information that describes the calculator as well as input variable information that describes the inputs available in your calculator.

The config.json file serves as the foundation for your calculator's user interface which is generated directly from the file. You can customize the layout, appearance, and input variables of your calculator by editing the information provided in the config.json file.

Layout#

The config.json file uses the JSON file format. At a high level the config starts with the following layout.

{
"meta": {
},
"input_variables": {
}
}

Meta Information#

The meta information is used to both describe the calculator as well as configure certain settings like access control.

Contact Objet#

When developing a calculator in the SkyCiv software framework, you may wish to provide information about the calculator's developer.

This is where the contact object comes into play. The contact object is an optional object that can be included in your calculator to display information about the developer. Specifically, this information is displayed in the 'View Module Info' option.

At a minimum this object must be include the email key. If no logo is included the SkyCiv Logo will be used.

{
"email": "Your Email",
"name": "Your Name",
"role": "Your Role",
"company": "Your Company",
"logo": "Logo URL",
"custom_header_html": "(Optional. Add a html string here to add it to the top of the report"
}
tip

Include the logo in the images folder of the calc pack. Reference the logo as /image_name.png to use this option.

Input Variable Information#

The input_variable object contains a set of nested objects that are used to build the input form of your calculator. Essentially, you can think of this part of the calculator as a form builder.

Each element in the form is represented by a separate object within the input_variable object. The key of each object represents the name of the related input variable. These elements appear in the user interface in the same order as they are listed in the JSON.

By specifying the necessary information in the input_variable object, you can create a user-friendly input form for your calculator. You can customize each input element, including its label, data type, default value, and other attributes.

Additional Input Variable Parameters#

KeyValue TypeDescription
s3d_onlyBooleanIf set to true, this input will be only be available in S3D.
disableBooleanIf set to true, this input will be disabled (greyed out) and not editable.
exclude_from_input_tableBooleanIf set to true, this input will be hidden from the main input table.
exclude_from_input_table_s3dBooleanIf set to true, this input will be hidden from the main input table in S3D only.
hide_info_tip_in_input_tableBooleanIf set to true, the information tips will be hidden from the input table of the design report.

display_units StringOverrides the units to display in the UI, report still shows the units key.
info_table StringOverrides the info tip in the Input Summary table.

Input Elements#

Input elements allow they user to interact and adjust sections the element in the calculator's user interface.

Number Element Example#

"section_width": {
"type": "number",
"label": "Section Width",
"symbol": "S_{W}", //optional, but looks better on reports
"units": "mm",
"info": "The width of the section.",
"default": 12,
"min": 3, //used in validation
"max": 400,
"step": 1, //increments the input by this number
"class": "section-width",
"nullable": true
}

Dynamic Min/Max Logic#

Dynamic min/max can be used to logically specify the min/max of an input based on another inputs value.

KeyDescription
greater_thanEnsures that the input will always be greater than the specified input.
less_thanEnsures that the input will always be less than to the specified input.
greater_than_or_equalEnsures that the input will always be greater than or equal to the specified input.
less_than_or_equalEnsures that the input will always be greater than or equal to the specified input.
equal_toEnsures that the input will always be equal to the specified input.
Example#
"heading_1": {
"type": "heading",
"label": "Width > Height"
},
"section_width": {
"type": "number",
"label": "Section Width",
"symbol": "S_{W}",
"units": "mm",
"info": "The width of the section.",
"default": 16,
"greater_than": "section_height"
},
"section_height": {
"type": "number",
"label": "Section Height",
"symbol": "S_{W}",
"units": "mm",
"info": "The width of the section.",
"default": 13
}

Text Element Example#

"text_input": {
"type": "text",
"label": "Text Input",
"default": "Some Text"
}

Display Inputs on One Row#

In some cases it may be useful to combine certain input together to be displayed on the same row. Two number or text elements are able to be displayed on the same row using the combine_with key. The labels and tooltip of this combined row can be overridden using the combined_label and combined_tooltip keys. In the report and calculations these inputs will still appear and be treated as if they were separate inputs.

tip

The input you are combining with should always appear after the input that contains the combine_with" key.

Display Inputs on One Row Example

"x_input": {
"type": "number",
"label": "X",
"units": "mm",
"info": "The X coordinate.",
"default": 12,
"min": 0,
"max": 100,
"step": 1,
"combine_with": "y_input",
"combined_tooltip": "The X and Y coordinates.",
"combined_label": "X,Y Coordinates"
},
"y_input": {
"type": "number",

tip

Images can be served directly from the calc pack by including an images folder. Reference the image as /image_name.png to use this option.

Heading Element Example#

"heading_1": {
"type": "heading",
"label": "My Heading"
}

Canvas Element Example#

"canvas": {
"type": "canvas",
"id": "ui-canvas"
},
note

Experimental support for sending canvas elements containing SVG elements as base64 to the calculate.js has now been added. To do this please include base_64_to_report: true as a key/value pair in the canvas element.

Div Element Example#

"div": {
"type": "div",
"id": "ui-div"
},
note

Experimental support for sending div elements containing SVG elements as base64 to the calculate.js has now been added. To do this please include base_64_to_report: true as a key/value pair in the div element.

Visibility Options#

This option allows users to show/hide certain parameters based on another field's input. For instance, if you have a dropdown to choose a shape, and want to show different inputs for circular VS rectangular, you can use use the visible_variables key:

"shape": {
"label": "Shape",
"s3d_only": true,
"type": "dropdown",
"options": [
{
"value": "circular",
"name": "Circular"
},
{
"selected": true,
"value": "hollow rectangular",
"name": "Hollow Rectangular"
}
],
"visible_variables": {
"custom": [
["show", "rect_image"],
["show", "shape-dimensions"],
["show", ".circular-input"]
],
"hollow rectangular": [
["show", "rect_image"],
["show", "b"],
["show", "d"],
["show", "t1"],
["show", "t2"],
["hide", ".circular-input"]
]
}
}

You can choose to show/hide based on the following options:

  • ["show", "all"] - will show all input variables
  • ["hide", "all"] - will hide all input variables (unless they also have a visible_variables key)
  • ["show", "section_width"] - will show the specific input section_width
  • ["show", ".circular-input"] - will show all inputs that have the class "circular-input"
tip

Want to add dynamic user interface elements like charts and drawings that can be updated based on user input? The canvas and div elements are perfect for the job, controlled from your ui.js file.

Settings (Optional)#
