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.
- Tooltips for emoji in Diagram Syntax doc tree: This issue proposes adding tooltips to the emoji displayed next to the names of various diagram types in the "Diagram Syntax" section of the documentation tree. The goal is to help users understand the meaning of these icons, as currently there is no reference explaining their significance, which can lead to confusion even for experienced users.
- log scale for
xychart-beta: This issue proposes adding ascalestring field to thexychart-betacomponent that defaults tolinearbut can also acceptlogas an option, enabling logarithmic scaling of chart data. This enhancement aims to allow users to maintain version control over graph descriptions with original (non-logged) values while displaying the data on a logarithmic scale, with potential for future extension to other scale types. - Unable to Style Sequence Diagram Title: This issue reports a problem with the inability to style the font size of the title in sequence diagrams created using Mermaid, where the user currently resorts to using a Markdown title as a workaround. The user notes that while other diagram types in Mermaid support title-related attributes for customization, such as QuadrantChartConfig, this functionality is not yet available for sequence diagrams, leading to very small and unreadable titles.
- SVG rendering formatting issues with markdown input: This issue addresses problems with SVG rendering when nodes in a diagram use markdown formatting, resulting in inconsistent visual output such as added height or text being cut off in the SVG files. Specifically, these formatting issues occur when opening the SVG in a new tab or downloading it from the editor, causing discrepancies between the expected and actual appearance of the diagram nodes.
- Vite build error with mermaid version 10.9.0: This issue describes a problem encountered when building a Vue 3 and Vite application that uses Mermaid version 10.9.0 to visualize graphs. While the development server runs without errors and displays the graphs correctly, the build process fails on application startup with a TypeError related to setting properties on an undefined object, preventing the Mermaid graphs from rendering as expected.
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: 6
Summarized Issues:
- Diagram Rendering and Syntax Issues: Several issues highlight problems with diagram rendering and syntax handling in Mermaid. These include the need for slanted or offset arrows in sequence diagrams to better represent race conditions, syntax errors caused by special characters or duplicate IDs, and failures in parsing labels with quotes or accented characters, all of which hinder proper diagram creation and display.
- issues/7151, issues/7154, issues/7156, issues/7157, issues/7159
- Performance and Usability Problems in Documentation: There is a significant usability issue where pressing a key causes the documentation page to reload diagrams continuously, resulting in slow performance and flickering elements. This problem makes navigation difficult, especially on pages like the ZenUML syntax documentation.
- issues/7152
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:
- Versioning and Changesets: This topic covers issues related to the absence of changesets in pull requests, which are necessary to trigger version bumps for affected packages. Without proper changesets, versioning may not update correctly, potentially causing confusion or deployment problems.
- issues/7153
- SVG Rendering Problems: This topic addresses problems with rendering Mermaid diagrams exported as SVG files, where text elements are present in the code but not visible in certain applications like GIMP. The issue suggests a rendering incompatibility specific to the application rather than the SVG file itself.
- issues/7158
