Support for Pasting and Copying via Clipboard Using Text Formats (XML/JSON) to speed up Microflow creation

8

Proposal:

I would like to propose a feature enhancement in Mendix Studio Pro to support the ability to paste structured data (e.g., XML or JSON) from the clipboard directly into microflows, domain models, and other relevant areas of the Mendix development environment.

The Problem:

Currently, developers cannot paste content from the clipboard into microflows or domain models unless it is manually inserted within Mendix. This limits flexibility and productivity when trying to automate or bulk-generate parts of the application, such as microflows that handle large datasets or domain models that need to be replicated.

Moreover, there is an additional limitation: you cannot copy and paste elements (e.g., microflows, domain models, widgets) between different versions of Mendix Studio Pro. If a developer is working in an older version of Mendix Studio Pro and wants to move a part of the application to a newer version, the native copy-paste functionality doesn't work. This forces the developer to manually rebuild components, which is not only time-consuming but also prone to errors.

Proposed Solution:

The idea is to introduce support for clipboard operations using XML or JSON structures. This feature would allow developers to paste pre-generated structures directly into Mendix Studio Pro, regardless of the version they are using. Specifically:

1. Pasting Microflow Logic:

   • Developers could generate XML or JSON structures that define a microflow to handle operations like populating a list of non-persistent entities from a spreadsheet table. The microflow would be generated externally (via scripts or tools) and then pasted into Mendix.
   • The structure could include actions such as creating a list, creating objects, setting attributes, and adding those objects to the list, all with defined canvas positions for proper layout in Mendix.

2. Pasting Domain Model Structures:

   • Similarly, developers could paste XML/JSON structures to build domain models, automatically creating entities and defining their attributes. This would accelerate the development process when defining large or repetitive data models.

3. Overcoming Version Compatibility Issues:

   • This feature would solve the issue of copying and pasting between different versions of Mendix Studio Pro. By using standardized XML/JSON formats, developers could easily transfer components from older projects to newer projects, without manually recreating elements. For instance, if a developer creates a complex microflow in an older version of Mendix, they could export the microflow as XML/JSON, then paste it directly into a project in a newer version of Mendix Studio Pro.

4. Special Copy Button:

   • Introduce a "Copy as XML/JSON" button within Mendix, allowing developers to export a microflow or domain model to the clipboard in XML or JSON format. This would provide a two-way integration, enabling developers to inspect and modify these structures externally before pasting them back into Mendix.

Example Use Case:

Consider the following scenario:

• A developer is working with a spreadsheet and needs to create a microflow that will generate a list of non-persistent DisplayLabel objects, each representing a label for UI fields like "First Name", "Last Name", and "Email Address".
• Using an external tool or a simple script, the developer generates an XML/JSON structure representing the microflow actions (create list, create object, set attributes, add object to list, etc.), along with their positions on the canvas.
• The developer pastes this structure into Mendix Studio Pro, which recognizes it and builds the corresponding microflow, complete with positioned actions.

Additionally, if this project were initially built in an older version of Mendix, the developer could use the same XML/JSON structure to transfer the microflow to a newer version of Mendix Studio Pro seamlessly.

Example XML Structure:

Here’s an example of the XML that could be generated externally and pasted into Mendix to create three DisplayLabel objects in a microflow. The DisplayLabel entity has fields FieldName and Label. The XML also includes x and y positions for each action to define the layout on the microflow canvas.

 

<microflow> 

<variable type="list" name="List<DisplayLabel>" />

  <!-- Creating first object -->  <action type="createObject" x="100" y="200">    <entity>DisplayLabel</entity>    <setAttribute name="FieldName" value="FirstName" />    <setAttribute name="Label" value="First Name" />  </action>  <action type="addToList" object="CurrentRow<DisplayLabel>" list="List<DisplayLabel>" x="300" y="200" />

 

  <!-- Creating second object -->  <action type="createObject" x="100" y="400">    <entity>DisplayLabel</entity>    <setAttribute name="FieldName" value="LastName" />    <setAttribute name="Label" value="Last Name" />  </action>  <action type="addToList" object="CurrentRow<DisplayLabel>" list="List<DisplayLabel>" x="300" y="400" />

 

  <!-- Creating third object -->  <action type="createObject" x="100" y="600">    <entity>DisplayLabel</entity>    <setAttribute name="FieldName" value="EmailAddress" />    <setAttribute name="Label" value="Email Address" />  </action>  <action type="addToList" object="CurrentRow<DisplayLabel>" list="List<DisplayLabel>" x="300" y="600" />

 

  <!-- Final List with all objects -->  <action type="finalAction" x="500" y="800">    <comment>This action can represent any further processing with the created list.</comment>  </action>

</microflow>

 

Explanation:

• Entity and Fields:

  • The entity is DisplayLabel with fields FieldName and Label. The microflow creates objects, sets these attributes, and adds the objects to a list.

• Positioning with x and y:

  • The x and y attributes define the canvas positions for each action, ensuring proper visual layout when the microflow is rendered in Mendix Studio Pro.

• Real-life Data:

  • The three objects represent a typical scenario where fields like FirstName, LastName, and EmailAddress need to be created dynamically for user interface labels.

Benefits:

1. Automation and Scripting: Developers could build scripts/tools that generate XML/JSON structures to automate large portions of their development work, significantly reducing manual efforts and errors.

2. Faster Development: Clipboard support for structured data allows developers to bulk-generate microflows, domain models, and other application components in a fraction of the time.

3. Version Compatibility: By introducing XML/JSON clipboard pasting, developers can easily copy components from older versions of Mendix Studio Pro to newer versions, overcoming the current limitation of version compatibility when copying and pasting elements. This will be especially helpful for teams that are transitioning between Mendix versions but still need to reuse components from older projects.

4. Flexibility: This feature would provide the ability to export and import XML/JSON structures, allowing developers to refine their projects externally and paste the results directly into Mendix.

5. Enhanced Developer Experience: This functionality would give developers a powerful way to integrate external tools into their Mendix workflows, improving productivity, consistency, and control over the development process.

Conclusion:

By adding support for XML/JSON clipboard pasting and copying, Mendix can empower developers to create complex microflows and domain models more efficiently and solve the issue of copying between different Mendix Studio Pro versions. This enhancement would also provide a two-way integration with external tools, allowing for the automatic generation of Mendix structures from spreadsheets, scripts, or other external sources. The feature would enhance productivity, reduce manual work, and open up new opportunities for automation in Mendix development.

While the above can be done throught the Mendix SDK, it easily gets complex if you want to implement it and maintain it, I believe this proposal would greatly simplify automating certain tasks and take out boring work for developers.
