Snekdown - More than just Markdown

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

Usage

``` USAGE: snekdown [OPTIONS] [SUBCOMMAND]

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

OPTIONS: -f, --format the output format [default: html]

ARGS: Path to the input file Path for the output file

SUBCOMMANDS: help Prints this message or the help of the given subcommand(s) render Default. Parse and render the document watch Watch the document and its imports and render on change ```

Syntax

Images

```md Simple Syntax !(url)

Extended syntax with a description description

Extended syntax with metadata to specify the size description[metadata]

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

When generating the html file the images are base64 embedded.

Quotes

```md Simple (default) Syntax

This is a quote

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.

```md <[path]

<[document.md]

<[style.css] ```

Tables

Tables MUST start with a pipe character |

```md 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.

```md 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.

```md String value [key = value]

String value [key = "String value"]

Integer value [key = 123]

Float value [key = 1.23]

Boolean [key]

Boolean [key = false]

Placeholder [key = [[placeholder]]]

Formatting [author = "The Great snek" date = [[date]] time = [[time]] display = "author - date at time"] ```

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 [[toc]][ordered] ```

Centered Text

|| These two lines || are centered

Inline

md *Italic* **Bold** ~Striked~ _Underlined_ ^Superscript^ `Monospace` :Emoji: §[#0C0]Colored text§[] §[red] red §[]

Bibliography

Bibliography entries can be defined and referenced anywhere in the document.

Definition: md

Usage: There is a book about snekdown[^book] and a github repo[^github].

Bibliography entries are only shown when used in the document.

Math

Snekdown allows the embedding of AsciiMath:

``` inline math $$ a^2 + b^2 = c^2 $$

Block Math $$$ A = [[1, 2],[3,4]] $$$ ```

The expression get's converted into MathML which is then converted by MathJax when loaded in the browser.

Roadmap

The end goal is to have a markup language with features similar to LaTeX.
