Snekdown - A wonderful markdown parser

This projects goal is to implement a fast markdown parser with an extended syntax fitted for my needs.

Usage

USAGE:
    snekdown [OPTIONS] <input> <output>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -f, --format <format>     [default: html]

ARGS:

    <output>

Syntax

Images

Simple Syntax
!(url)

Extended syntax with a description
![description](url)

Extended syntax with metadata to specify the size
![description](url)[metadata]

Extended syntax with metadata and no description
!(url)[metadata]

Quotes

Simple (default) Syntax

Multiline
> This is a 
> Multiline Quote

Quote with metadata (e.g. Author)
[author=Trivernis year=2020 display='{{author}} - {{year}}']> This is a quote with metadata

Imports

Imports can be used to import a different document to be attached to the main document. Imports are parsed via multithreading.

<[path]

Tables

Tables MUST start with a pipe character |

Standalone header:
| header | header | header

Header with rows
| header | header | header
|--------|--------|-------
| row    | row    | row

Placeholders

Placeholders can be used to insert special elements in a specific place. Placeholders are always case insensitive.

Insert the table of contents
[[TOC]]

Insert the current date
[[date]]

Insert the current time
[[time]]

Metadata

Additional metadata can be provided for some elements.

Boolean
[key] 

Boolean
[key = false]

Placeholder

Usage

Hide a section (including subsections) in the TOC
#[toc-hidden] Section

Set the size of an image
!(url)[width = 42% height=auto]

Set the source of a quote
[author=Me date=[[date]] display="{{author}} - {{date}}"]> It's me

Set options for placeholders
