DEPRECATED

I don't maintain this project anymore. I originally made this project because I wanted a way to create markdowndocuments in C#. I decided on the fly to also add different kinds of documents, that I have no need for. I think the project does too much and I'm not happy with some of the design choices I made. I'll be creating a seperate project just for markdowndocument creation.

DocumentBuilder

DocumentBuilder is a library that uses the Builder pattern to enable you to declaratively create different kinds of documents easily. It is not a full-fledged solution for creating complex documents. DocumentBuilder focuses on ease of use.

The following formats are currently supported:

• Markdown
• HTML
• Excel

DocumentBuilder exposes a GenericDocumentBuilder class that can be used to create a markdown or HTML document, it does not support Excel since its document structure is too different. DocumentBuilder also exposes a MarkdownDocumentBuilder and an HTMLDocumentBuilder. These can be extended with Markdown or HTML-specific elements.

Creating a document

Below are examples of how you can use the document builders provided by DocumentBuilder to create markdown, HTML and Excel documents. You can write your document to a stream by providing an output stream, or to a file by providing a file path.

// Given the following data:
var header1 = "Header1";
var header2 = "Header2";
var header3 = "Header3";
var header4 = "Header4";
var paragraph = "An interesting paragraph";
var imageName = "imageName";
var imagePath = "./image";
var imageCaption = "This is an image";
var blockquote = "blockquote";
var lanuage = "C#";
var codeblock = "codeblock";
var raw = "raw";

var orderedList = new List<string>
{
    "an",
    "ordered",
    "list"
};

var unorderedList = new List<string>
{
    "an",
    "unordered",
    "list"
};

Generic

The generic document builder allows you to create generic documents that can easily be written to a stream as either Markdown or HTML.

// Create a document using the generic document builder
var outputStream = new MemoryStream();

var documentBuilder = new DocumentBuilder(options)
    .AddHeader1(header1)
    .AddHeader2(header2)
    .AddHeader3(header3)
    .AddHeader4(header4)
    .AddParagraph(paragraph)
    .AddImage(imageName, imagePath, imageCaption)
    .AddUnorderedList(unorderedList)
    .AddOrderedList(orderedList)
    .AddTable(productTableRows) // More on tables below
    .BuildAsync(outputStream, DocumentType.Markdown); // Or HTML (DocumentType.HTML)

Markdown

The MarkdownDocumentBuilder allows you to create Markdown documents, it is not yet different from the GenericDocumentBuilder, but might include Markdown-specific functionality in the future.

// Create a document using the markdown document builder
var outputStream = new MemoryStream();

var markdownDocumentBuilder = new MarkdownDocumentBuilder(options)
    .AddHeader1(header1)
    .AddHeader2(header2)
    .AddHeader3(header3)
    .AddHeader4(header4)
    .AddParagraph(paragraph)
    .AddImage(imageName, imagePath, imageCaption)
    .AddUnorderedList(unorderedList)
    .AddOrderedList(orderedList)
    .AddTable(productTableRows) // More on tables below
    .AddHorizontalRule()
    .AddBlockquote(blockquote)
    .AddFencedCodeblock(codeblock, language)
    .AddRaw(raw)
    .BuildAsync(outputStream); // Or file path

HTML

The HTMLDocumentBuilder allows you to create Markdown documents, it is not yet different from the GenericDocumentBuilder, but might include HTML-specific functionality in the future.

// Create a document using the html document builder
var outputStream = new MemoryStream();

var htmlDocumentBuilder = new HtmlDocumentBuilder(options)
    .AddHeader1(header1)
    .AddHeader2(header2)
    .AddHeader3(header3)
    .AddHeader4(header4)
    .AddImage(imageName, imagePath, imageCaption)
    .AddParagraph(paragraph)
    .AddUnorderedList(unorderedList)
    .AddOrderedList(orderedList)
    .AddTable(productTableRows) // More on tables below
    .AddRaw(raw)
    .BuildAsync(outputStream); // Or file path

Excel

The Excel document builder allows you to create Excel documents. Since the structure of Excel documents is not comparable to Markdown or HTML, it's not supported by the GenericDocumentBuilder.

// Create a document using the excel document builder
var outputStream = new MemoryStream();

var excelDocumentBuilder = new ExcelDocumentBuilder(options)
    .AddWorksheet("my-worksheet-name")
    .AddTable(productTableRows) // More on tables below
    .BuildAsync(outputStream);  // Or file path

Tables

DocumentBuilder supports the creation of tables by creating a POCO (Plain Old C# Object). It will use the name of the property as the column name and will order the columns as defined on the POCO. There are options available to configure this.

Creating a Table

1. Define a POCO

public class ProductTableRow
{
    public string Id { get; set; }
    public string Amount { get; set; }
    public string Price { get; set; }
    public string Description { get; set; }
}

2. Put your POCOs in an IEnumerable

var productTableRows = new List<ProductTableRow>
{
    productTableRowOne,
    productTableRowTwo,
    productTableRowThree,
};

3. Use it inside a document builder to generate a table

var outputStream = new MemoryStream();

var markdownDocumentBuilder = new MarkdownDocumentBuilder(options)
    .AddTable(productTableRows)
    .BuildAsync(outputStream);

NOTE: In case of using an object, the values written to the table cell will be the object's ToString() method.

If the provided table row is an empty enumerable, it will be skipped.

Options

DocumentOptions

All document types have the following options:

Option	Type	Description	DefaultValue
LineEnding	LineEnding	What line ending to use	Environment
BehaviorOnEmptyEnumerable	EmptyEnumerableBehavior	What behavior to display when a provided enumerable is empty	SkipRender

LineEndings: Environment, Windows, Linux EmptyEnumerableBehavior: SkipRender, Render, ThrowException

Markdown

MarkdownTableOptions

Option	Type	Description	DefaultValue
Formatting	Formatting	How to align the table	AlignColumns
BoldColumnNames	bool	Wheter to have the column names in bold text	false
DefaultAlignment	Alignment	What default (github) alignment to use	None

Formatting: AlignColumns, None Alignment: None, Left, Right, Center

HTML

HtmlDocumentOptions

Option	Type	Description	DefaultValue
LineEnding	LineEnding	What line ending to use	Environment
IndentationType	IndentationType	What type of indentation to use	Spaces
IndentationSize	int	The size of one indentation	2

IndentationTypes: Spaces, Tabs

Attributes

You can annotate your POCO properties with the Column attribute.

public class ProductTableRow
{
    [Column(name: "ProductId", order: 1)] // Overwrite the column name
    public string Id { get; set; }

    [Column(nameof(Description))] // Not specifying an order will default the value to int.Max
    public string Description { get; set; }

    public string Price { get; set; }

    [Column(alignment: Alignment.Center)] // Applies github style markdown to align the column
    public string Amount { get; set; }
}

You can annotate your POCO properties with the IgnoreColumn attribute. This will ignore the column when converting to a document.

public class ProductTableRow
{
    [Column(name: "ProductId", order: 1)] // Overwrite the column name
    public string Id { get; set; }

    [Column(nameof(Description))] // Not specifying an order will default the value to int.Max
    public string Description { get; set; }

    [IgnoreColumn]
    public string Price { get; set; }

    [Column(alignment: Alignment.Center)] // Applies github style markdown to align the column
    public string Amount { get; set; }
}

Future work

If there are any features that you would like to see implemented, please create an issue with the enhancement label on the Github Issues page. Note that I am working on this project in my free time, and might not have time to implement your request (or simply decline it since I don't see the added value for the project).

Currently, I'm still looking to implement the following (no deadline set):

• Word support
• More insertables for Excel
• Better styling options for Excel
