A tool for users on tilde servers to cross publish blog posts to HTML and Gemini.

cargo install crosspub

Linux binaries are available on the Releases page

Run

make
sudo make install

crosspub is designed to not need any configuration out of the box. To start create a containing directory and initialize it.

mkdir website
crosspub --init

This creates two directories, one for posts (blogs and articles written on a specific day) and one for topics (evolving documents that change and grow over time), as well as creating a default config file.

crosspub content is written in gemtext, a lightweight markup language. Files should end in .gmi.

Next, change the settings in your config.toml, see Basic Configuration.

Create posts directories in your HTML and Gemini root directories

mkdir ~/public_html/posts
mkdir ~/public_gemini/posts

Change these paths to match your configuration.

When you're ready to generate your website just navigate to the directory you initialized and run

crosspub

All gemtext files in posts/ must start with a mandatory TOML frontmatter

---
title = "Example Title"
date = "YYYY-MM-DD"
slug = "example"
---

Content goes here
...

The "slug" is a small string that becomes part of the filename, basically a shortened title.

Files in topics/ start with a slightly different frontmatter that lacks a date field.

---
title = "Example Topic"
slug = "example_topic"
---

...

The config file is located at $HOME/.config/crosspub/config.toml

• name is the title of your site
• url is the base URL of the site (not including the tilde part)
• username is your username, your tilde extension on the site minus the ~ character
• html_root and gemini_root are the paths to your public_html and public_gemini files.

crosspub allows you to write a bio and have it generate an About page. First make sure you have a directory for crosspub data:

mkdir -p ~/.local/share/crosspub

Next create a file in that directory called about.gmi. This is just a plain gemtext file, no frontmatter.

Finally edit ~/.config/crosspub/config.toml so that use_about_page = true

If desired, more unique sites can be created by utilizing custom templates. First create the proper directories

mkdir -p ~/.local/share/crosspub/templates/html
mkdir -p ~/.local/share/crosspub/templates/gemini

The default templates are located at /usr/share/crosspub/templates/. It is recommended to look at the built-in templates for an explanation of how they work.

crosspub uses 5 templates each for HTML and Gemini

• index
• post
• topic
• postlist
• about

Some or all of these templates can be shadowed by ones located in ~/.local/share/crosspub/templates.

Similar to the templates, site-wide CSS can be modified. User CSS should go in ~/.local/share/crosspub/templates/html/style.css

The default index.html and index.gmi templates both list posts on the homepage. If you'd like to move this listing to a separate page set post_list = true in your config. This creates a listing at {HTML_ROOT}/posts/posts.html and {GEMINI_ROOT}/posts/posts.gmi. crosspub will NOT automatically link to these listings, so it's up to you to modify other templates as necessary.
