A wish to use import statements in the handlebars custom helper functions...?

[rustyleaf]

I am attempting to simply require a file into that helper function but it seems to me that when it runs it is running from the "renderer" path location.
/Applications/Obsidian.app/Contents/Resources/electron.asar/renderer
The absolute path for requiring a file works but would be nice to have relative paths.
Not sure if this is doable with ease...?

//example file to require: planets.js

module.exports = {
  planet_symbol: {
    sun: '☉',
    earth: '⊗',
    moon: '☾',
    mars: '♂',
    venus: '♀',
    mercury: '☿',
    jupiter: '♃',
    saturn: '♄',
    neptune: '♆',
    uranus: '♅',
  }
}
// js 'require' with path relative to the helper function file...
const Planets = require('./planets.js');
console.log(Planets.planet_symbol[sun])

The contents of the supplied additional handlebars custom helper file are read into the importer and used as the body of a function using the following code:

let initJsonHelpers = new Function('handlebars', await helperfile.text());
if (initJsonHelpers) initJsonHelpers(handlebars);

The function is then called and the handlebars parameter is provided for the helper file to register it's own helpers. My testing used a file containing the following:

function hb_farling() {
	let orig = arguments[0];
	orig += ' from Helper';
	return orig;
}
handlebars.registerHelper('farling', hb_farling);

Thanks @farling42. I love what the helper functions can do and I love the functionality of your plugin!

I have got the helper functions working and have included an example of how I am trying to require the file... but it seems it goes beyond my basic javascript knowledge - because of how electron packages the module I got a bit lost.

Thought I would clarify - but no big issue if it gets complicated i will just use absolute paths to require the file.

console.log(__dirname);
/// Applications/Obsidian.app/Contents/Resources/electron.asar/renderer

const Elements = require('./elements.js');

/*
 I can add some of my extra js objects like this (below) *rt_expand_center()*
 that can be used in the helper functions etc.. but I was hoping to 
 use require's to bring them in from a local directory so I can use them like on line 36
 but it seems due to the path when the actual function runs
 it cannot find the file.

const bodygraph_centers = {
  identity: 'G-center',
  life_force: 'Sacral',
  mind: 'Ajna',
  emotion: 'Solar Plexus',
  expression: 'Throat',
  intuition: 'Spleen',
  drive: 'Root',
  willpower: 'Heart/Ego',
  inspiration: 'Head',
};

const clean_string = (str) => {
  return str.toLowerCase().replace(/\s/g, '_');
};

function rt_get_planet_symbol() {
  const planet = arguments[0];
  const _planet = clean_string(planet);
  const element = Elements.planet_symbol[_planet];
  let str = `${planet} [${element}]`;
  return str;
}

handlebars.registerHelper('get_planet_symbol', rt_get_planet_symbol);

function rt_expand_center() {
  const type = arguments[0];
  const _type = clean_string(type);
  const center = bodygraph_centers[_type];

  let str = `center: ${center}`;
  str += '\n';
  str += `center_type: ${type}`;
  return str;
}

handlebars.registerHelper('expand_center', rt_expand_center);

You could try using the full path from the root of your vault, such as:

const Elements = require(app.vault.root.path + 'foldername/elements.js');

That's perfect!!! It works...! Thanks so much!
