Trigger Templater without creating a new file

[art.genosse]

I would like to add some some datview-queries with templater to existing notes.
For automatization I use the variable [[<% tp.file.title %>]].

It works (in the sens that it adds the title of the note) when I crate a new not.
It doesn’t work when I add it to an existing note

How to trigger Templeter for existing notes? (When I only want to add snippets with variables to an existing note)?

[Yurcee]

when it comes to variables, i usually use dataviewjs because they are easier to work with (no need to learn the documentation)

as for the dataview documentation, look up dv.view and use cases on the forum

otherwise you can simply paste a dataviewjs query with a templater script: at cursor position with tR += or at a particular line (say, last line), or even replace a line

e.g your script would start like this:

<%*
const dv = this.app.plugins.plugins["dataview"].api;
const currentFile = app.workspace.getActiveFile();
if (!currentFile) {
    new Notice("No active file found.");
    return;
}

const editor = app.workspace.activeEditor.editor;

• you ought to learn this last line, for instance: make notes in a different vault on obsidian related functions
• you ought to learn that if you want to embed dataviewjs functionality in a templater script, you need to add const dv = this.app.plugins.plugins["dataview"].api;
• all these stuff i had to gather from the forum myself so i’m no coder, you know…

then you have your dvjs query written and you format it like this (this is my use case, yours will be different):

// Create the dataviewjs query with the extracted parts
const dataviewjsQuery = `
\`\`\`dataviewjs
const regex = ${regexPattern};
const myPage = dv.page("${fileName}");

const content = await dv.io.load(myPage.file.path);
const lines = content.split('\\n');
const matches = lines.map(line => {
    const match = line.match(regex);
    if (match) {
        let part1 = match[1].trim();
        // Remove trailing ")" if present
        if (part1.endsWith('")')) {
            part1 = part1.slice(0, -2).trim();
        }
        return { part1: part1, part2: match[2].replace(/\\|/g, '').trim() };
    } else {
        return null;
    }
}).filter(match => match);

dv.table(
    [\`File\`, \`Content\`],
    matches.map(match => [\`**\${match.part1}\**`, match.part2])
);
\`\`\`
`;

• you can use a ${tp.file.title} variable what you tried or dv.current
• notice how the dataviewjsQuery variable is built and the way you needed to add \ before backticks

in the last part you will do the insert, based on where you want it – in my case it was selection replacement:
editor.replaceSelection(dataviewjsQuery.trim());
but you can navigate the cursor to the end of the file, using:
this.app.workspace.activeLeaf.view.editor.setCursor({ line: 99999, ch: 0 });
then you can add the dataviewjsQuery with tR +=

then finally you close the script with:

%>

using the ingredients above, you can have your script written with a 2024 version gpt (gpt4o)
