# Jekyll Theme TFG <!-- omit in toc -->

TFG is a tiny friendly giant Jekyll theme for powering blogs. The name of this theme is from [Koenigsegg Gemera](https://www.koenigsegg.com/gemera/)'s engine ["Tiny Friendly Giant"](https://www.koenigsegg.com/gemera/tiny-friendly-giant-engine/). It is small when it comes to emissions and consumption, and at the same time, it is big when it comes to power, torque, and sound. The target of this theme is similar—While providing friendly and powerful blog functions, try to keep the code and the design as tiny as possible.

TFG is built on [Tachyons](https://tachyons.io/).

## Installation

Add this line to your Jekyll site's `Gemfile`:

```ruby
gem "jekyll-theme-tfg"
```

And add this line to your Jekyll site's `_config.yml`:

```yaml
theme: jekyll-theme-tfg
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install jekyll-theme-tfg

If your website is hosted on GitHub Pages, you can install this theme via [`jekyll-remote-theme`](https://github.com/benbalter/jekyll-remote-theme).

Add the following to your `Gemfile`:

```ruby
gem "jekyll-remote-theme"
```

And add this line to your Jekyll site's `_config.yml`:

```yml
plugins:
  - jekyll-remote-theme
```

Add the following to your site's `_config.yml`:

```yml
remote_theme: vfvong/jekyll-theme-tfg
```

## Usage

Ease of use is one of the design goals of TFG. Basically, you only need to refer to the [`_config.yml`](https://github.com/vfvong/jekyll-theme-tfg/blob/gh-pages/_config.yml) file of the demo to set the basic parameters required to run the website.

### Customization

You can of course fork the entire repository and make custom changes on your copy, but there is a much cleaner way: after referencing the theme, you just need to copy the [`_sass/tfg/_variables.scss`](https://github.com/vfvong/jekyll-theme-tfg/blob/main/_sass/tfg/_variables.scss) file to your repository in the corresponding path, and then modify some variables, you can customize the color and fonts you like.

If you want to put some extra data into the `<head>`, you don't need to overwrite the entire `_includes/head.html` file, and you just need to create a file `_includes/custom-head.html` in your repository, and then put your data into there.

### Archive Pages

TFG provides a template `archive` to archive posts by years, categories, or tags.

If you want to show an archive page of years, just create a file and put these front matter in it:

```yml
---
layout: archive
type: years
title: Archive by Years
---
```

Similarly, if you want to show an archive page of categories, just create a file and put these front matter in it:

```yml
---
layout: archive
type: categories
title: Archive by Categories
---
```

Besides, if you want the categories and tags displayed in the post to link to the archive pages, you need to configure the paths to the category and tag archive pages in the `_config.yml` file, for example:

```yml
categories_path: /categories/
tags_path: /tags/
```

### Google Analytics 4

TFG support the [Google Analytics 4](https://support.google.com/analytics/answer/10089681). To enable it, just set the Measurement ID in the `_config.yml`, for example,

```yml
google_analytics: G-XXXXXXXXXX
```

### Disqus

To enable [Disqus](https://disqus.com/), just set the [Disqus shortname](https://help.disqus.com/en/articles/1717111-what-s-a-shortname) in the `_config.yml`, for example,

```yml
disqus: <your disqus shortname>
```

### MathJax

TFG relies on the [MathJax](https://www.mathjax.org/) to render math. The MathJax is disabled by default. You need to set `math: true` on the page where you want to enable the MathJax.

### Navigation

The navigation in TFG is very easy to configure, just specify the titles and URLs in the [`_data/navigation.yml`](https://github.com/vfvong/jekyll-theme-tfg/blob/gh-pages/_data/navigation.yml) file, for example,

```yml
- title: Home
  url: /
- title: About
  url: /about.html
- title: Archive
  url: /archive.html
```

### Social Links

The social links in TFG is also very easy to connfigure. You don't need to import any large SVG file to render the icons because TFG supports the [Font Awesome](https://fontawesome.com/). Specify the titles, URLs, and icons in the [`_data/social.yml`](https://github.com/vfvong/jekyll-theme-tfg/blob/gh-pages/_data/social.yml) file, for example,

```yml
- title: Email
  url: mailto:[email protected]
  icon: fas fa-envelope
- title: Twitter
  url: https://twitter.com/vfvong
  icon: fab fa-twitter
- title: GitHub
  url: https://github.com/vfvong
  icon: fab fa-github
```

## Development

To set up your environment to develop this theme, run `bundle install`.

Your theme is setup just like a normal Jekyll site! To test your theme, run `bundle exec jekyll serve` and open your browser at `http://localhost:4000`. This starts a Jekyll server using your theme. Add pages, documents, data, etc. like normal to test your theme's contents. As you make modifications to your theme and to your content, your site will regenerate and you should see the changes in the browser after a refresh, just like normal.

When your theme is released, only the files in `_layouts`, `_includes`, `_sass` and `assets` tracked with Git will be bundled.
To add a custom directory to your theme-gem, please edit the regexp in `jekyll-theme-tfg.gemspec` accordingly.
