Tenets of Markdown to HTML conversion

Converting Markdown to HTML involves adhering to certain tenets or principles to ensure the process is accurate, efficient, and consistent. Here are the key tenets:

  1. Simplicity and Readability:
  • Markdown: Designed to be easy to read and write with minimal syntax.
  • HTML Output: Should maintain the simplicity and readability of the original Markdown.
  1. Correctness and Accuracy:
  • The conversion should accurately map Markdown syntax to the correct HTML elements.
  • No loss of information or incorrect rendering should occur during the conversion.
  1. Efficiency:
  • The conversion process should be computationally efficient, handling large documents without significant performance issues.
  • Libraries and tools should optimize parsing and rendering for speed.
  1. Consistency:
  • The same Markdown input should consistently produce the same HTML output.
  • Conversion rules should be strictly followed to avoid discrepancies.
  1. Extensibility and Customizability:
  • The conversion process should allow for customization to handle non-standard or extended Markdown syntax.
  • Users should be able to add plugins or extensions to enhance functionality.
  1. Handling Edge Cases and Errors Gracefully:
  • The converter should handle edge cases and malformed Markdown gracefully.
  • Providing meaningful error messages or fallback mechanisms is essential.
  1. Preservation of Semantics:
  • The semantic meaning of the original Markdown content should be preserved in the HTML output.
  • Structural elements like headings, lists, and emphasis should maintain their intended purpose.
  1. Accessibility:
  • The generated HTML should adhere to web accessibility standards (e.g., WCAG).
  • Ensuring that the content is accessible to all users, including those using screen readers or other assistive technologies.
  1. Security:
  • The conversion process should sanitize inputs to prevent injection attacks or malicious code execution.
  • Libraries should provide options to filter out potentially harmful content (e.g., script tags).
  1. Cross-Platform Compatibility:
  • The conversion tool should work across different platforms and environments.
  • Ensuring that the output HTML renders correctly on all major browsers and devices.

Application of Tenets in Conversion Process

  1. Simplicity and Readability:
  • Markdown: # Heading
  • HTML: <h1>Heading</h1>
  1. Correctness and Accuracy:
  • Markdown: **bold text**
  • HTML: <strong>bold text</strong>
  1. Efficiency:
  • Using efficient algorithms to tokenize and parse Markdown.
  • Libraries like marked in JavaScript and markdown in Python are optimized for performance.
  1. Consistency:
  • Markdown: - List item
  • HTML: <ul><li>List item</li></ul>
  1. Extensibility and Customizability:
  • Extending Markdown syntax to support tables or footnotes.
  • Using plugins in marked to add custom rendering functions.
  1. Handling Edge Cases and Errors Gracefully:
  • Handling malformed Markdown: *unclosed emphasis
  • Outputting safe HTML with warnings or auto-corrections.
  1. Preservation of Semantics:
  • Markdown: ## Subheading
  • HTML: <h2>Subheading</h2>
  1. Accessibility:
  • Ensuring HTML has appropriate ARIA roles and attributes.
  • Adding alt text for images in Markdown: ![Alt text](image.jpg)
  1. Security:
  • Sanitizing input to remove script tags: <script>alert('XSS');</script>
  • Using libraries like DOMPurify in conjunction with Markdown converters.
  1. Cross-Platform Compatibility:
    • Ensuring HTML uses standard elements and attributes that work across all browsers.
    • Testing output on different devices to ensure consistency.

By adhering to these tenets, the conversion process from Markdown to HTML can be robust, reliable, and suitable for a wide range of applications.



Markdown Guide

Markdown is a lightweight markup language that you can use to add formatting elements to plaintext text documents. Created by John Gruber in 2004, Markdown is now one of the world's most popular markup languages.

Basics

Headers

Use the # symbol to create headers. The number of # symbols indicates the header level.

# H1
## H2
### H3
#### H4
##### H5
###### H6

Emphasis

You can add emphasis by using asterisks (*) or underscores (_).

  • Bold: **bold text** or __bold text__
  • Italic: *italic text* or _italic text_
  • ~~Strikethrough~~: ~~strikethrough text~~
**bold text**
*italic text*
~~strikethrough text~~

Lists

Unordered Lists

Use *, +, or - to create unordered lists.

- Item 1
- Item 2
  - Subitem 1
  - Subitem 2

Ordered Lists

Use numbers followed by periods to create ordered lists.

1. First item
2. Second item
3. Third item
   1. Subitem 1
   2. Subitem 2

Links

To create a link, use the following syntax:

[link text](URL)

Example:

[Creative Commons](https://creativecommons.org)

Images

To add an image, use the same syntax as links but with an exclamation mark (!) in front.

![alt text](image URL)

Example:

![Creative Commons Logo](https://creativecommons.org/wp-content/uploads/2019/02/ccheart_black.png)

Blockquotes

Use the > symbol to create blockquotes.

> This is a blockquote.

Code

Inline Code

Use backticks (`) to create inline code.

Here is some `inline code`.

Code Blocks

Use triple backticks (```) or indent the code by four spaces to create code blocks.

```
This is a code block.
```

Horizontal Rules

Use three or more hyphens (---), asterisks (***), or underscores (___) to create a horizontal rule.

---

Tables

You can create tables using pipes (|) and hyphens (-).

| Header 1 | Header 2 |
| -------- | -------- |
| Row 1    | Data 1   |
| Row 2    | Data 2   |

Task Lists

Use - [ ] for unchecked boxes and - [x] for checked boxes.

- [ ] Task 1
- [x] Task 2

Extended Features

Some Markdown processors support additional features, such as:

Footnotes

Here's a sentence with a footnote. [^1]

[^1]: This is the footnote.

Definition Lists

First Term
: This is the definition of the first term.

Second Term
: This is the definition of the second term.

Strikethrough

~~This text is strikethrough~~

Task Lists (GitHub Flavored Markdown)

- [x] Completed task
- [ ] Incomplete task

Tips

  • Consistency: Stick to one style of formatting to maintain consistency.
  • Readability: Ensure that the Markdown document is readable in plaintext.
  • Preview: Use a Markdown previewer to check your formatting before finalizing the document.
