Hexo: Helpers not available when using hexo.render

[cyberwombat]

I have a console plugin which calls hexo.load() then proceed to do a custom render of a post. All works fine except for any helper I have added. Seems like these either get loaded too late or not at all when using the render API. I've also tried a standalone script that creates a new instance of Hexo and inits it per API docs with same result. How does one create a console script that can render with helpers?

@cyberwombat Helpers works for themes, such as .ejs files.

Do helpers only work for .ejs and not for Swig/Nunjucks?

I also need more info about this.
In a custom generator I use the render API:

hexo.extend.generator.register('gen1', function (locals) {
    return {
        path: 'gen1.html',
        data: hexo.render.renderSync({path: 'template.ejs'}, locals); // <--- ERROR here
    };
}

template.ejs

<p> Text <%-partial('partialTemplate') %>

The code throws error because partial is not defined.
It seems helpers aren't loaded or unavailable.
Any thoughts?

@Xuanwo so is not possible to load partials from files inside the /source folder?

[NoahDragon]

@cesarvarela I don't think so.

Commenting here because I have the exact same issue as @giuseppelt

Trying to use hexo.render.renderSync and my template file won't run because has a partial() inside of it. I get the error partial is not defined.

Is there no way around this? It seemed intuitive to me that hexo.render would render just like all my other templates...
