2 Auto Frontmatter

I have a couple of solutions to automatically create a frontmatter.

Snippet

I started from snippet...

markdown.json

 "Id": {
    "prefix": "Docusaurus-id",
    "body": [
      "---",
      "id: $TM_FILENAME_BASE",
      "title: ${TM_FILENAME_BASE/([^-]+)(-*)/${1:/capitalize}${2:+ }/g}",
      "date: $CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATE $CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND",
      "---",
      "",
      "$1"
    ],
    "description": "Print out Docusaurus markdown title"
  },

To run the snippet, start a new file, press Ctrl + Space, type id and choose Docusaurus-id.

Macro: createAutoFrontmatter

Then I created the createAutoFrontmatter macro using a multi-command extension. This macro is more convenient.

To use it, just press Alt+G c.

Macro: updateAutoFrontmatter

If you've changed the name of markdown file and want to update its frontmatter, just press Alt+G u.

tip

Currently, this macro not only changes the frontmatter of the file, but also saves the edited file and returns focus to the sidebar to continue working with the files.

settings.json

    {
      "command": "multiCommand.updateAutoFrontmatter",
      "label": "Markdown",
      "description": "Update Auto Frontmatter",
      "sequence": [
        "workbench.action.focusFirstEditorGroup",
        "cursorTop",
        "cursorDown",
        "cut",
        "cut",
        {
          "command": "editor.action.insertSnippet",
          "args": {
            "snippet": "id: $TM_FILENAME_BASE\n"
          }
        },
        {
          "command": "editor.action.insertSnippet",
          "args": {
            "snippet": "title: ${TM_FILENAME_BASE/([^-]+)(-*)/${1:/capitalize}${2:+ }/g}"
          }
        },
        "cursorLineStartSelect",
        {
          "command": "editor.action.insertSnippet",
          "args": {
            "snippet": "${TM_SELECTED_TEXT/(\\d+)\\s(?=\\d)/$1./g}\n"
          }
        },
        "type",
        "workbench.action.files.save",
        "workbench.action.focusSideBar"
      ]
    },

Add a Shortcut

keybindings.json

  {
    "key": "alt+g u",
    "command": "extension.multiCommand.execute",
    "args": { "command": "multiCommand.updateAutoFrontmatter" },
  },
