What's New in Oxygen JSON Editor 27.1

March 24, 2025

Related version: 27.0    

Oxygen JSON Editor version 27.1 is an incremental release of the industry-leading bundle of tools for JSON developers and collaborators.

When editing JSON documents with an associated schema in Author mode, the content completion feature now automatically inserts the required content, helping users maintain faster workflows and more consistent designs.

Enhancements to the Git Client add-on ensure a smoother user experience. Highlighted among the various improvements are the new Cherry-pick and Merge actions in the Git History view that make it easier to incorporate changes from selected commits.

This release also offers new APIs, refreshed components, security enhancements, and numerous bug fixes to refine the overall user experience.

There are changes in:

AI Positron Assistant

Preview All AI-Proposed Changes to Files

You now have the ability to preview all the changes in the documents that the AI proposes to create or update while processing particular actions (e.g. Split Topic or Create Topics). You are no longer required to confirm that you want to overwrite files. Instead, you can preview the proposed changes in all files and choose how to proceed in each instance. This helps to ensure control over AI-proposed modifications.

Notification for Unchanged Content

When an AI action processes content but does not result in any changes, you are now informed, eliminating the need for unnecessary previews or visual inspection. This improvement saves time and ensures a smoother workflow.

Fix Validation Problems

The Intelligent Agents category now includes a new Fix Validation Problems action. This action validates the current document and suggests fixes for all identified issues, streamlining both the validation process and the resolution of validation problems, ensuring high-quality content.

AI-based MathML Generation

The new Formula/Equation action (located in the Content Generation category) leverages AI to generate MathML formulas based on your descriptions. This feature simplifies the creation of complex mathematical representations and enhances technical documentation workflows.

AI-based Code Annotations

The new Annotate Code AI action (located in the Development category) can be used to generate XML comments within the code found in the current selection, at the cursor location, or in the whole document. The generated annotations explain key concepts of the code. This action is available for XSLT, Schematron, and XSD documents.

Resolve Comments from Contextual Menu

Invoking the Resolve Comments AI action is now much more efficient as it now appears directly in the contextual menu when you right-click a comment callout box in the editor or in the Review view. The action changes the selected content based on the suggestions within comments and then removes the comments.

New AI Callback Functions to Enable Dynamic Workflows

The plugin now includes several new AI callback functions, which are specialized mechanisms enabling the AI to dynamically invoke external processing and use the results in generating its response. These new functions can be used to invoke another AI action, to find all the available AI actions, and to validate a document, thus empowering users to create complex, dynamic workflows as part of a custom AI action.
  • invoke_ai_action - This callback function invokes an AI action that enables the delegation of processing to other AI actions, thus you can use a divide-et-impera approach to simplify and optimize the AI action processing.
  • retrieve_all_ai_actions - Instead of specifying a predefined set of AI actions that can be invoked, you can use this callback function that returns all the defined actions. This allows the AI to discover all the available AI actions and invoke them dynamically as needed.
  • validate_document_content - When processing or generating content, an AI action can now use this callback function that validates a document, ensuring that the generated content is valid. In case of errors, it offers the opportunity to automatically correct the detected problems.

Invoke Positron Actions from XPath

A new XPath function (ai:invoke-action) has been introduced, enabling you to seamlessly invoke an AI Positron action from any XPath context (such as XSLT, XQuery, Schematron, etc.) by providing the action ID, contextual text, and the content to be processed.

Multi-agent Architecture for Create Topics

The Create Topics action has been restructured using a multi-agent architecture and now leverages the invoke_ai_action() function. These improvements ensure better adherence to system instructions and more consistent execution.

Export and Import Chat Sessions

It is now possible to export a conversation with the AI to a JSON file using the new Export Chat action that appears in the Actions menu. You can also import a conversation from a JSON file using the new Import Chat action. This feature is especially helpful for debugging purposes or to resume an exported conversation with the AI. For example, an exported conversation could be sent to the developer of a custom action to help them investigate issues that were encountered and then you could import the previous conversation once you are ready to resume.

Disable/Enable All AI Features for a Specific Project

An option was added in the Preferences page for you to disable (or enable) all the AI features at project level (or globally for all projects). This allows you to control which projects have AI features available.

Updated Default Model

For the SaaS distribution and for the OpenAI connector in the Enterprise distribution, the default AI model has been updated to gpt-4o-2024-11-20, the latest gpt-4o snapshot from OpenAI.

JSON

Improved Content Completion in Author Mode

The Content Completion feature in Author mode for JSON documents has been improved with new functionality. Required content is now automatically inserted when editing JSON documents that have an associated JSON Schema, thus saving you time and ensuring consistency in your documents.

Quick Fixes

More Ways to Access Quick Fix Proposals

Now, quick fix suggestions for validation issues are also available in the contextual menu of the status bar at the bottom of the editor where the description of the current validation issue is displayed, providing even more convenient ways to quickly solve validation issues while editing XML documents.

Add-ons

Oxygen offers a range of add-ons that can be utilized to expand its functionality.

Git Client Improvements

Various improvements were made to the Git Client add-on:
  • The new Cherry-pick action (available in the Git History view) applies the changes from the selected commit to the current branch.
  • The Merge action is now available in the Git History view. You can use this action to merge an entire branch, or to integrate all changes from a selected commit and any of its ancestors that are not already in the current branch.
  • The Git History side-view can now be linked to the active editor using the Link with Editor option. Selecting an editor for a file within the same repository will automatically display that file's history.
  • It is now possible to sign commits using SSH keys.
  • For Git resources, the contextual menu in the DITA Maps Manager now includes a Git submenu with two actions. The Show history action displays the history of the selected resource within the DITA Maps Manager. The Show blame action reveals who made the last modification on each line of a file and in which commit.
  • Actions to create a repository in the project folder were added in the contextual menu of the Project side-view (look for Create repository here) and the Git main menu (see Create repository in project).
  • The JGit component was updated to version 7.1.0.
  • Other minor improvements and various bug fixes were implemented.

Miscellaneous

Speed Improvement for Format and Indent Files

The Format and Indent Files action is now done in parallel, decreasing the time it takes to format and indent lots of files at once.

API Additions

Custom Help for Plugin Preferences Page

The new OptionPagePluginExtension.getHelpPageURL() API method was added, allowing a plugin-contributed preferences page to provide its own help page URL.

Create a Link Label

The new OxygenUIComponentsFactory.createLinkLabel(String, ActionListener) API can be used to create a link label (a clickable label that looks and acts like a link).

Convert Visual Offset to Line/Column Information

The new AuthorDocumentProvider.getLineColumnMapping API method allows an offset in the Author visual editor to be converted to line/column information in the serialized XML document.
