Content format

Lake uses its own markup language, Lake Markup Language (LML), which is similar to HTML. LML defines the content within the editor and provides various tags and attributes for formatting and embedding content.

Selection

The <focus /> tag represents the current position of the cursor.

<p>This is the paragraph of text.<focus /></p>

The <anchor /> and <focus /> tags together define the range of content selected by the user.

<p><anchor />This is the paragraph of text.<focus /></p>

Box

The <lake-box> tag is used to embed content to enhance editing capabilities. It supports the following attributes:

• type: inline | block

  Determines whether the box is rendered as an inline or block element.

• name: string

  Specifies the type of embedded content.

• value: Base64 string

  Contains the encoded data for the box.

• focus: start | center | end

  Indicates the cursor position within the box.

<lake-box type="block" name="hr" focus="start"></lake-box>
<lake-box type="inline" name="image" value="..." focus="end"></lake-box>

Headings

The <h1> to <h6> tags represent six levels of section headings. <h1> is the highest level and <h6> is the lowest.

<h1>Heading level 1</h1>
<h2>Heading level 2</h2>
<h3>Heading level 3</h3>
<h4>Heading level 4</h4>
<h5>Heading level 5</h5>
<h6>Heading level 6</h6>

Paragraph

The <p> tag represents a paragraph.

<p>This is the first paragraph of text.</p>
<p>This is the second paragraph.</p>

Line break

The <br /> tag represents a line break within text.

<p>First text<br />Second text</p>

Block quotation

The <blockquote> tag represents a block quotation.

<blockquote>This is a block quotation.</blockquote>

Numbered list

Numbered lists use the <ol> tag with <li> elements. The start attribute sets the starting number, and the indent attribute defines sub-levels.

<ol start="1"><li>first item</li></ol>
<ol start="2"><li>second item</li></ol>
<ol start="1" indent="1"><li>second item first subitem</li></ol>
<ol start="2" indent="1"><li>second item second subitem</li></ol>
<ol start="3" indent="1"><li>second item third subitem</li></ol>
<ol start="1"><li>third item</li></ol>

Bulleted list

Bulleted lists use the <ul> tag with <li> elements. Indentation is similarly managed with the indent attribute.

<ul><li>first item</li></ul>
<ul><li>second item</li></ul>
<ul indent="1"><li>second item first subitem</li></ul>
<ul indent="1"><li>second item second subitem</li></ul>
<ul indent="1"><li>second item third subitem</li></ul>
<ul><li>third item</li></ul>

Checklist

For checklist items, specify type="checklist" on the <ul> tag. Each <li> includes a value attribute indicating its state (true for checked, false for unchecked).

<ul type="checklist"><li value="true">first item</li></ul>
<ul type="checklist"><li value="false">second item</li></ul>
<ul type="checklist" indent="1"><li value="false">second item first subitem</li></ul>
<ul type="checklist" indent="1"><li value="false">second item second subitem</li></ul>
<ul type="checklist" indent="1"><li value="false">second item third subitem</li></ul>
<ul type="checklist"><li value="false">third item</li></ul>

Table

Tables are defined using <table>, <tr>, and <td> tags. The <tr> tag represents a row of cells in a table. The <td> tag represents a cell of a table that contains data.

<table>
  <tr>
    <td>Person</td>
    <td>Most interest in</td>
    <td>Age</td>
  </tr>
  <tr>
    <td>Chris</td>
    <td>HTML tables</td>
