gmi-web/README.md

This project is home to a [gmi-to-html reference](#gmi-to-html), a [gmi.css](#gmi-css) stylesheet and the [gmi-web(1) ](#gmi-web-1) command-line tool.

# 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>  ↔  >
````

`<li>` must be wrapped with a `<ul>` tag. Take care to render `<pre>` blocks with their original formatting, DO NOT indent the generated
HTML for these tags.

`<a>` tags are categorized as [inline](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flow_Layout/Block_and_Inline_Layout_in_Normal_Flow#elements_participating_in_an_inline_formatting_context) which CSS [Normal Flow](https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Normal_Flow) presents _vertically_—Gemini only deals with _horizontally_ flowing content, this can be addressed by using [`display: block;` at the CSS level.](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flow_Layout/Block_and_Inline_Layout_in_Normal_Flow#changing_the_formatting_context_an_element_participates_in)

## optional: inline media

If a link is consumable by `<img>`, `<audio>` or `<video>` you may insert the respective tag inline, instead of an `<a>`. It's a good idea to also include the `controls` property.

These are categorized as inline just like `<a>` and will need `display: block;` styling. Images and video should also have `max-width: 100%;` so they don't overflow the body.

## `<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://" />
<meta name="color-scheme" content="dark light" />
```

# gmi.css

[core.css](./core.css) is a maximally miniminal stylesheet that overrides the default CSS Normal Flow to render content horizontally in a Gemini way. [gmi.css](./gmi.css) extends upon that slightly with font and color options. The default values are optimized for readability and mobile-friendliness and may be customized by adding a style property to `<html>`.

```html
<head>
  <!-- assuming you wanna host a copy and link to it... -->
  <link rel="stylesheet" type="text/css" href="gmi.css" />
  <meta name="color-scheme" content="dark light" />
  <!-- ... -->
</head>
<html style="--foreground:#555555; --background:#9EEBCF;">
  <!-- ... -->
</html>
```

The `--foreground` and `--background` variables will be inverted when
[prefers-color-scheme](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-color-scheme) is "dark".

  gmi-web --image jpg --audio mp3 --image png --body < doc.gmi

See the gmi-web(1) man page for more information.
```

## config

A JSON file can be passed to `--config` for conveniently applying any option without using the command-line flag. For example a `web.json` file with the following contents...

```json
{
  "html": "en",
  "descriptions": 200,
  "foreground": "#137752",
  "background": "#F4F4F4"
}
```

...can be used like so:

```sh
gmi-web --config web.json $(find ~/gmi/dst -name '*.gmi')
```
