I. News

1.1 Recent Version Releases:

The current version of this repository is @mermaid-js/layout-elk@0.1.7

1.2 Version Information:

On November 27, 2024, a patch update was released for the Mermaid library, which included a fix for offset calculations related to the diamond shape when handling intersections, as contributed by @knsv.

II. Issues

2.1 Top 5 Active Issues:

We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.

1. mermaid.parse always return false in Node.js but truthy value when parsing the same result in browser: This issue describes a problem where the mermaid.parse function returns false when executed in a Node.js environment, but returns a truthy value indicating a valid diagram type when the same code is run in a browser. The user is questioning whether the .parse function requires a browser environment to function correctly, as the discrepancy in behavior suggests a dependency on browser-specific features.

   • The comments reveal that the issue is due to a missing dependency on DOMPurify in the Node.js environment, which is required by the mermaid library. Another user confirms experiencing the same problem, indicating it might be a common issue.
   • Number of comments this week: 2

Since there were fewer than 5 open issues, all of the open issues have been listed above.

2.2 Top 5 Stale Issues:

We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.

1. vite build failure for 10.9.0: This issue involves a build failure in version 10.9.0 of a project using Vite with vite-react-swc, where the build process succeeds during development (npm run dev) but fails during the build and preview stages (npm run build & npm run preview) due to a TypeError in the browser. The error message indicates an "Uncaught (in promise) TypeError: Cannot set properties of undefined (setting 'prototype')" which suggests a problem with the JavaScript code execution, and it is noted that version 9.4 does not exhibit this issue, although there are slight API differences.
2. Control brackets around loopText and friends: This issue proposes that the Mermaid project should provide a feature to control the addition of brackets around elements like loopText in sequence diagrams, allowing users to customize their appearance through CSS. The request highlights the need for flexibility in styling, such as hiding brackets to match user-specific design preferences, and includes an example of how this can be achieved with custom CSS.
3. Lots of whitespace around C4 graph.: This issue involves excessive whitespace being generated around C4 context diagrams when using the Mermaid tool, which is not observed with other types of diagrams. The problem can be reproduced by exporting a diagram using the command mmdc -o out.png -t neutral -i example.mmd, and the user has provided a code sample and a screenshot to illustrate the issue.
4. Mermaid versions after v9.2.2 cannot be injected into Firefox addons: This issue involves a problem with injecting the mermaid.min.js script into Firefox browser extensions, where versions after v9.2.2 fail to inject due to a Content Security Policy (CSP) restriction that blocks a call to Function(). The problem does not occur in Chromium-based browsers, and the issue has persisted since the release of Mermaid v9.3.0, with the user unable to identify the specific change causing the failure.
5. support for Block diagrams to merge row blocks: This issue is a feature request for the Mermaid project, specifically seeking support for merging row blocks within block diagrams to enhance their visual representation. The user provides a code sample and screenshots to illustrate the desired outcome, highlighting the current limitations and expressing the need for this enhancement to improve diagram functionality.

2.3 Open Issues

This section lists, groups, and then summarizes issues that were created within the last week in the repository.

Issues Opened This Week: 5

Summarized Issues:

• Mermaid Diagram Customization: Users have requested enhancements to the Mermaid tool to allow for more customization options in diagrams. These requests include the ability to customize participant colors in sequence diagrams and assign custom IDs to edges for individual styling, which are currently limited or not possible.
  • issues/6367, issues/6372

• Mermaid Diagram Functionality Issues: There are several issues affecting the functionality of Mermaid diagrams, including problems with the mermaid.parse function in Node.js environments and text labels being truncated in diagrams. These issues suggest a need for better compatibility and rendering consistency across different environments and diagram elements.
  • issues/6370, issues/6379

• Entity-Relationship Diagram Enhancement: A feature request has been made to enhance the Entity-Relationship Diagram (ERD) functionality in Mermaid to support relationships involving more than two entities. This enhancement would allow for more complex and accurate representations of data relationships.
  • issues/6366

2.4 Closed Issues

This section lists, groups, and then summarizes issues that were closed within the last week in the repository. This section also links the associated pull requests if applicable.

Issues Closed This Week: 2

Summarized Issues:

• Generic Type Display in Class Diagrams: The issue involves a problem where a generic type is correctly displayed in a class diagram unless the class is used as a base for another class. When inheritance occurs, the generic type information disappears from the interface name, indicating a need for consistent display of generic types regardless of inheritance.
  • issues/6356

• Arrowhead Color Consistency in Flowcharts: This issue addresses the need for the arrowhead color in flowchart diagrams to match the color of the edge. A code snippet demonstrates the current problem where the visual outcome does not meet the expected rendering, highlighting a discrepancy in color consistency.
  • issues/6369
