Swift library to programmatically generate Markdown output and files

MarkdownGenerator

A small Swift library to generate Markdown documents.

Features

• ✅ Easily generate Markdown from structured data
• ✅ Extendible: make your classes and structs MarkdownConvertible
• ✅ Swift Package Manager compatible
• ✅ Linux compatible 🐧

MarkdownConvertible

Types conforming to the MarkdownConvertible protocol can be rendered as a markdown string, by implementing the .markdown computed property.

Out of the box, MarkdownGenerator provides the following Markdown elements:

• Unordered lists
• Ordered lists
• Tables
• Block-quotes
• Code Blocks
• Collapsible Blocks
• Images
• Links
• Headings

Please take a look at the following examples, or read the reference documentation.

Lists

List can be nested to any levels and contain single or multi-line items. Lists can be ordered, unordered, or mixed.

let list = MarkdownList(items: ["🍏", "🍌", "🍊", "🍇"])
print(list.markdown)

Generates the following output:

-   🍏
-   🍌
-   🍊
-   🍇

Which renders as:

• 🍏
• 🍌
• 🍊
• 🍇

Tables

While Markdown didn't have support for tables originally, most modern Markdown readers (including GitHub) properly render tables nowadays.

let data: [[String]] = [
    ["🍏", "Apple", "Fruits"],
    ["🍊", "Orange", "Fruits"],
    ["🥖", "Bread", "Bakery"],
]
let table = MarkdownTable(headers: ["", "Name", "Department"], data: data)
print(table.markdown)

Generates the following output:

|   | Name | Department |
| - | ---- | ---------- |
| 🍏 | Apple | Fruits |
| 🍊 | Orange | Fruits |
| 🥖 | Bread | Bakery |

Which renders as:

	Name	Department
🍏	Apple	Fruits
🍊	Orange	Fruits
🥖	Bread	Bakery

Blockquotes

Any MarkdownConvertible content (including String) can be easily .blockquoted.

let input = """
## This is a header.

1.   This is the first list item.
2.   This is the second list item.

Here's some example code:

    return shell_exec("echo $input | $markdown_script");

> This is a quote.
"""

print(input.blockquoted.markdown)

Generates the following output:

> ## This is a header.
>
> 1.   This is the first list item.
> 2.   This is the second list item.
>
> Here's some example code:
>
>     return shell_exec("echo $input | $markdown_script");
>
> > This is a quote.

Which renders as:

This is a header.

1. This is the first list item.
2. This is the second list item.

Here's some example code:

return shell_exec("echo $input | $markdown_script");

This is a quote.

Collapsible Blocks

Collapsible blocks look great on GitHub and other Markdown viewers. Great way to provide detailed content without cluttering the output.

let details: [MarkdownConvertible] = [
    MarkdownHeader(title: "Title"),
    MarkdownList(items: ["🐶", "🐱", "🦊"]),
    MarkdownTable(headers: ["Name", "Count"], data: [["Dog", "1"], ["Cat", "2"]]),
    MarkdownCodeBlock(code: "let foo = Bar()", style: .backticks(language: "swift"))
]

print(MarkdownCollapsibleSection(summary: "This is cool stuff", details: details).markdown)

Generates the following output:

<details><summary>This is cool stuff</summary>

# Title

-   🐶
-   🐱
-   🦊

| Name | Count |
| ---- | ----- |
| Dog | 1 |
| Cat | 2 |

```swift
let foo = Bar()
```
</details>

Which renders as (click to expand):

This is cool stuff

Title

• 🐶
• 🐱
• 🦊

Name	Count
Dog	1
Cat	2

let foo = Bar()
