Set Publish Flag shortcut destroys frontmatter meta-tags

[janfromm]

I encountered a problem when using the "Digital Garden: Add Publish Flag" feature. It seems to corrupt the meta-tags in the frontmatter. For example:
dg-metatags: { description: "some description" }
gets replaced by:
dg-metatags: [object Object]
This breaks the structure and format of the metadata.

Suggested Solution
To avoid this issue, I propose modifying the setPublishFlagValue() function so that only the dg-publish flag is updated without affecting other frontmatter fields. Here's an updated version of the function:

setPublishFlagValue(value) {
  return __async(this, null, function* () {
    const activeFile = this.getActiveFile(this.app.workspace);
    if (!activeFile) {
      return;
    }

    const fileContent = yield this.app.vault.read(activeFile);

    // Extract the frontmatter by matching the first three lines
    const frontMatterMatch = fileContent.match(/^---\n([\s\S]+?)\n---/);
    
    if (!frontMatterMatch) {
      // If no frontmatter exists, add it
      const newFrontMatter = `---\ndg-publish: ${value}\n---\n\n${fileContent}`;
      yield this.app.vault.modify(activeFile, newFrontMatter);
      return;
    }

    // Parse the frontmatter
    let frontMatter = frontMatterMatch[1];

    // Modify only the "dg-publish" flag
    if (/dg-publish:\s*(true|false)/.test(frontMatter)) {
      // Replace the existing "dg-publish" flag
      frontMatter = frontMatter.replace(/dg-publish:\s*(true|false)/, `dg-publish: ${value}`);
    } else {
      // If the "dg-publish" flag doesn't exist, add it
      frontMatter += `\ndg-publish: ${value}`;
    }

    // Create the new file content
    const newFileContent = fileContent.replace(/^---\n[\s\S]+?\n---/, `---\n${frontMatter}\n---`);

    // Save the file with the updated frontmatter
    yield this.app.vault.modify(activeFile, newFileContent);
  });
}

Why This Works:
It directly manipulates the frontmatter, ensuring other fields like dg-metatags remain intact.
Only the dg-publish flag is updated or added if it doesn’t exist.
The rest of the frontmatter stays unchanged, avoiding issues with formatting or data loss.
