Obsidian: Get and Set Parent

README.md

Get and Set Parent

These scripts are useful when you want to create a QuickAdd macro to remember the active note as the parent, create a new note, and then set a note property with a link to the parent. The QuickAdd macro would look like the following:

1. Get Parent
2. <Template>
3. Set Parent

Make sure the Template step opens the new note.

Get Parent.js

const SETTING = {
    ALIAS: "Use Alias",
};

const VARIABLE = "kherge:parent";

async function getParent({ app, variables }, settings) {
    delete variables[VARIABLE];

    const file = app.workspace.getActiveFile();

    if (!file) {
        throw new Error("No active file found.");
    }

    if (settings[SETTING.ALIAS]) {
        const cache = app.metadataCache.getFileCache(file);

        if (cache?.frontmatter?.aliases) {
            variables[VARIABLE] = `[[${file.basename}|${cache.frontmatter.aliases[0]}]]`;
        }
    }

    if (!variables[VARIABLE]) {
        variables[VARIABLE] = `[[${file.basename}]]`;
    }
}

module.exports = {
    entry: getParent,
    settings: {
        name: "Get Parent",
        author: "Kevin Herrera",
        options: {
            [SETTING.ALIAS]: {
                defaultValue: true,
                description: "Use the first alias of the parent note, if it exists?",
                type: "checkbox",
            }
        }
    }
};

Set Parent.js

const SETTING = {
    PROPERTY: "Parent Property",
};

const VARIABLE = "kherge:parent";

async function setParent({ app, variables }, settings) {
    if (!variables[VARIABLE]) {
        throw new Error("No parent has been selected.");
    }

    const file = app.workspace.getActiveFile();

    if (!file) {
        throw new Error("No active file found.");
    }

    await app.fileManager.processFrontMatter(
        file,
        (frontmatter) => {
            frontmatter[settings[SETTING.PROPERTY]] = variables[VARIABLE];
        }
    );

    delete variables[VARIABLE];
}

module.exports = {
    entry: setParent,
    settings: {
        name: "Set Parent",
        author: "Kevin Herrera",
        options: {
            [SETTING.PROPERTY]: {
                defaultValue: "parent",
                description: "What is the name of the parent property in the child note?",
                type: "text",
            }
        }
    }
};
