Install the Galleon Theme

Add the theme as a dependency to your Gatsby site.

npm i --save @shetharp/gatsby-theme-galleon
# or
yarn add @shetharp/gatsby-theme-galleon

Add the theme to your gatsby-config.js file

module.exports = {
  plugins: ["@shetharp/gatsby-theme-galleon"],
};

Modify the theme options and site metadata in your gatsby-config.js file.
Create .mdx files for your site's pages or posts.
Shadow, override, and customize the theme to fit your needs.

Start with the Galleon Workspace

To start developing your own theme using this repo as a starting point:

gatsby new gatsby-theme-custom https://github.com/shetharp/gatsby-theme-galleon
cd gatsby-theme-custom
yarn
yarn workspace demo develop

Replace gatsby-theme-custom with whatever you wish to name your theme.

The theme workspace directory contains the components, styles, and theme configurations.

You should update the package.json to match the details for your theme (such as name, author, repository, etc.)
This workspace can be used to publish your theme as its own npm package

The demo workspace directory contains the content, components, and styles for an example site that consumes the theme.

You should update the package.json to include your theme as a dependency. Make sure the name of the dependency matches the name in your theme's package.json file!
You should then update the gatsby-config.js to include your theme as a plugin
This workspace can be used to deploy a demo site for your theme

Features

Galleon builds on top of the features provided in @lekoarts/gatsby-theme-minimal-blog.

MDX
Theme UI
Light mode / Dark mode
Typography driven, minimal style
Tags/Categories support
Syntax highlighting for code blocks with prism-react-renderer and react-live support. Also allows adding line numbers, line highlighting, language tabs, and file titles.

Code Highlighting

If you want to change certain code styles or add additional language tabs, you need to shadow the file src/@shetharp/gatsby-theme-galleon/styles/code.js.

Language tabs:

When you add a language (such as e.g. js or javascript) to the code block, a little tab will appear at the top left corner.

```js
// code goes here
```

Code titles:

You can display a title (e.g. the file path) above the code block.

```jsx:title=your-title
// code goes here
```

Or without a specific language:

```:title=your-title
// code goes here
```

Line highlighting:

You can highlight single or multiple (or both) lines in a code block. You need to add a language.

```js {2,4-5}
const test = 3;
const foo = "bar";
const harry = "potter";
const hermione = "granger";
const ron = "weasley";
```

Hide line numbers:

If you want to hide line numbers you can either globally disable them (see Theme options) or on a block-by-block basis. You can also combine that with the other attributes.

```noLineNumbers
// code goes here
```

Shadowing

Please read the guide Shadowing in Gatsby Themes to understand how to customize the this theme! In general, you will want to place your files in src/@shetharp/gatsby-theme-galleon/ to shadow or override files.

Adding content

Adding a new blog post

New blog posts will be shown on the index page (the three most recent ones) of this theme and on the blog overview page. They can be added by creating MDX files inside content/posts. General setup:

Create a new folder inside content/posts
Create a new index.mdx file, and add the frontmatter
Add images to the created folder (from step 1) you want to reference in your blog post
Reference an image as your banner in the frontmatter
Write your content below the frontmatter
Add a slug to the frontmatter to use a custom slug, e.g. slug: "/my-slug" (Optional)

📍 The fields description and banner are optional! If no description is provided, an excerpt of the blog post will be used. If no banner is provided, the default siteImage (from siteMetadata) is used.

📍 The date field has to be written in the format YYYY-MM-DD!

Adding a new page

Additional pages can be created by placing MDX files inside contents/pages, e.g. an "About" or "Contact" page. You'll manually need to link to those pages, for example by adding them to the navigation (in siteMetadata). General instructions:

Create a new folder inside content/pages
Create a new index.mdx file, and add the frontmatter
Write your content below the frontmatter
Optionally add files/images to the folder you want to reference from the page
