Installation

To install it into your Publish package, add it as a dependency within your Package.swift manifest:

let package = Package(
    …
    dependencies: [
        …
        .package(url: "https://github.com/sowenjub/CasperishTheme.git", .branch("main"))
    ],
    targets: [
        .target(
            …
            dependencies: [
                …
                "CasperishTheme"
            ]
        )
    ]
    ...
)

Configuration

Open main.swift and customize it using the example below

import Foundation
import Publish
import Plot
import CasperishTheme // 1

// This type acts as the configuration for your website.
struct MyWebsite: Website, CasperishWebsite { // 2
    enum SectionID: String, WebsiteSectionID {
        // Add the sections that you want your website to contain here:
        case posts
    }

    struct ItemMetadata: WebsiteItemMetadata, CasperishWebsiteItemMetadata { // 3
        // Add any site-specific metadata that you want to use here.
       var cover: String? // 3 bis
    }

    // Update these properties to configure your website:
    var url = URL(string: "https://your-website-url.com")!
    var name = "MyWebsite"
    var description = "A description of MyWebsite"
    var language: Language { .english }
    var imagePath: Path? { nil }

    // 4
    // Update these properties to configure your casperish-website:
    var rootPathString = "/"
    var headerColor = "#424242"
    var cover = ""
    var author = "Arnaud Joubay"
    var avatar = "http://i.pravatar.cc/300"
    var bio = "Swift & Rails Indie Maker"
    var icon = "🏝"
    var newsletterAction = ""
    var contacts: [(ContactPoint, String)] { [
        (.twitter, "sowenjub"),
        (.dev, "sowenjub"),
        (.linkedIn, "arnaudjoubay"),
        (.gitHub, "sowenjub"),
        (.stackoverflow, "229688"),
    ]}
}

// This will generate your website using the built-in Foundation theme:
try MyWebsite().publish(
    withTheme: .casperish,
    additionalSteps: [
        .installPlugin(.readingTime()),
        .installPlugin(.pygments()),
    ],
    plugins: [.pygments()]
)  // 5

1. Well, you need the CasperishTheme package obviously
2. Your Website must adopt the CasperishWebsite protocol, which enables theme-specific configurations (see 4.)
3. Your ItemMetadata must adopt the CasperishWebsiteItemMetadata, allowing you to add cover photos to each of your posts (which are items in the Publish jargon). So we also need to add the line var cover: String? inside.
4. This is where you can really make this theme your own:
   • rootPathString this allows you to publish the website in a subfolder, such as on GitHub Pages without a custom domain name. Leave it to "/" if your site will leave at the root domain
   • headerColor hexadecimal code for the header’s background-color. The cover image will hide it if you use one.
   • cover optional path to the cover image. Leave blank ("") if you want to use the headerColor instead. If you have a cover.jpg image, the path should be "/cover.jpg" if your image is at the root of your /Resources folder (don’t forget the / or it won’t work on subpages).
   • author and bio are displayed just above the footer
   • avatar is the path to your profile picture, displayed for each post. The path should be "/my avatar.jpg" if your image is at the root of your /Resources folder.
   • icon can be an emoji or any short text suitable to be the icon in the navigation bar on mobile
   • • newsletterAction leave blank ("") if you want to hide the newsletter, otherwise replace with the target URL
   • contacts is an array of nicknames used to display links to your web profiles in the header (on desktop). For now, it only supports Twitter, Dev.to, LinkedIn, Github and Stack Overflow.
5. To generate your website you need to include the 2 plugins that ship with the theme

Usage

Set your title in the front matter

Publish is smart, it will use the first title in your post content as the title, but this means your title will appear twice: once above the cover image, and once below.

Instead, you should set it in your front matter.

Add covers to your posts, or not

If you want to add a cover image to your post, add it in your posts’ front matter. To use /Resources/first_post.jpg as you cover for this post, add cover: /first_post.jpg like below:

---
title: My first post
cover: /first_post.jpg
date: 2020-08-04 00:46
description: A description of my first post.
tags: life, anew
---
# My first post

My first post's text.

If you don’t want a cover, just remove the cover line.

Organizing your content

In order to organize your content, you can play two variables:

• your categories (displayed in the menu, declared in your main.swift as SectionID)
• your tags (displayed above each post, declared in each post’s front matter)

Navigation: Pages & Sections

All pages and sections will appear in the navigation menu, first the pages, then the sections.

Modifying the theme

This theme is powered by Tailwind CSS.

If you want to customize the css, you will need to edit the Resources/CasperishTheme/theme.css file, and regenerate the styles.css file.

cd Resources/CasperishTheme
npx tailwindcss build theme.css -o styles.css -c tailwind.config.js
