Markdown and Chart Rendering

Companion replies are rendered as rich Markdown. Headings, lists, tables, code blocks, formulas, and diagrams can be read directly in the chat, and copied either as plain text or as Markdown.

Supported Content

Content	Behavior
Markdown	Headings, lists, tables, and code blocks are formatted automatically
Mermaid	Rendered as diagrams with fullscreen preview
KaTeX / LaTeX	Inline and block math are typeset
.md paths	Trusted assistant replies can expose clickable local Markdown paths
Images	Image attachments can be previewed and exported

Mermaid Diagrams

Mermaid blocks are rendered inline. Click a diagram to open fullscreen preview, then zoom with the wheel, drag to pan, or reset the view to fit the screen.

If rendering fails, DesireCore keeps the original code block so you can ask the Companion to fix it.

Math Formulas

DesireCore supports common LaTeX syntax:

• Inline: $E = mc^2$
• Block: $$\int_a^b f(x) dx$$

Long formulas scroll inside the message bubble instead of breaking the layout.

Rendering Examples

The following examples show common Markdown elements in Companion replies:

Code blocks (with syntax highlighting and one-click copying):

```python
def hello():
    print("Hello, DesireCore!")
```

Tables (automatically aligned, with horizontal scrolling on narrow screens):

| Feature | Status |
|---------|--------|
| Rendering | ✅ |
| Copying | ✅ |

Mermaid diagrams (automatically rendered as visual diagrams):

```mermaid
graph LR
    A[User input] --> B[Companion processing]
    B --> C[Return results]
```

Math formulas (typeset with KaTeX):

Inline: $E = mc^2$
Block: $$\int_0^1 x^2 dx = \frac{1}{3}$$

Troubleshooting Rendering

Issue	What Happens	What to Do
Invalid Mermaid syntax	The original code block is kept instead of a diagram	Ask the Companion to correct the syntax and output it again
Invalid LaTeX formatting	The raw LaTeX source is displayed	Check that the $ delimiters are paired
Inconsistent table column counts	Some columns may be misaligned	Make sure each row has the same number of | characters
Unclosed code block	Subsequent content is treated as code	Make sure opening and closing triple backticks (```) are paired

Practical Tips

• If a Companion's Mermaid diagram does not render, tell it: "The Mermaid syntax is invalid. Please fix it."
• To copy diagram source, use "Copy Markdown" instead of "Copy".
• Long formulas scroll horizontally inside the message bubble without breaking the layout.

Copying

Action	Result
Copy	Plain text for chat or regular documents
Copy Markdown	Preserves headings, lists, code blocks, tables, and diagram source
