This repo is home to:

- [the gmi-web(1) command-line tool](#gmi-web-1)
- [a gmi.css stylesheet](#gmi-css)
# gmi-to-html
The converted Gemini document should exist inside the `<body>`. Consider if sharing the page with other HTML to put the core document inside `<main>`. Each available line-type may be translated using the following guide:
````
<p>
<a> ↔ =>
<pre> ↔ ```
<h[1-3]> ↔ #[##]
<li> ↔ *
<blockquote> ↔ >
````
List items must be wrapped with a `<ul>` tag. Empty lines should be represented as `<p><br></p>`. Take care to render `<pre>` blocks with their original formatting, DO NOT indent the generated
HTML for these tags.
`<a>` tags are considered [inline elements](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flow_Layout/Block_and_Inline_Layout_in_Normal_Flow) which has presentational implications—CSS 2.1's _Normal Flow_ renders inline elements vertically. Gemini only deals with horizontally flowing content, this can be addressed by either re-defining `a {display: block;}` at the CSS level or by wrapping `<a>` tags in a "block" level element such as `<p>`. [MDN: Changing Element Levels](https://developer.mozilla.org/en-US/docs/Web/HTML/Inline_elements#changing_element_levels)
### Optional: inline media
If a link is consumable by `<img>`, `<audio>` or `<video>` you may insert the respective tag inline instead of an `<a>`. Images and video should be styled to have `max-width: 100%;` so they don't overflow the body. It's a good idea to also include the "controls" attribute. These are all categorized as inline just like `<a>` and should be handled accordingly.
## `<html>` and `<head>`
When producing a complete and valid HTML5 document the first declaration is the required `<!DOCTYPE html>`. At the root of a document is the `<html>` tag which should have a [`lang` attribute which declares the overall language of the page](https://www.w3.org/International/questions/qa-html-language-declarations) and if necessary should also include `dir="rtl"`.
Additionally a `<head>` tag with at least the following must also be included:
```html
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1" />
<title></title>
```
These may also be nice to have:
```html
<meta name="author" content="" />
<meta name="description" content="" />
<link rel="canonical" href="gemini://" />
```

# gmi.css
Optimized for readability, predictability and mobile-friendliness. Ships with a handful of customizable variables.
The `--foreground` and `--background` variables will be inverted when
`prefers-color-scheme` is "dark" which is a system-level preference on
devices.
Any of the variables can be customized by adding a style to the `<html>` element.
```html
<html style="--foreground:#555555; --background:#9EEBCF;"></html>
```
