## Block Reference

### Headings

```python
from markdownpal.blocks import H1Block, H2Block, H3Block, H4Block, H5Block, H6Block

doc.append(H1Block("Title"))       # # Title
doc.append(H2Block("Section"))     # ## Section
doc.append(H3Block("Subsection"))  # ### Subsection

Text

from markdownpal.blocks import TextBlock, QuoteBlock, HRBlock, CommentBlock

doc.append(TextBlock("A plain paragraph."))
doc.append(QuoteBlock("A blockquote.\nSpanning multiple lines."))
doc.append(HRBlock())                               # ---
doc.append(CommentBlock("Hidden in rendered output."))  # <!-- ... -->

Code

from markdownpal.blocks import CodeBlock

doc.append(CodeBlock("print('hello')", lang="python"))
doc.append(CodeBlock("SELECT * FROM users;", lang="sql"))
doc.append(CodeBlock("no language specified"))

Lists

from markdownpal.blocks import ULBlock, OLBlock, TaskListBlock

doc.append(ULBlock(["Apples", "Bananas", "Cherries"]))

doc.append(OLBlock(["Install", "Configure", "Run"]))

doc.append(TaskListBlock([
    ("Write tests", True),
    ("Write code", True),
    ("Deploy",      False),
]))

Table

from markdownpal.blocks import TableBlock

doc.append(TableBlock(
    headers=["Name", "Role", "Status"],
    rows=[
        ["Alice", "Engineer", "Active"],
        ["Bob",   "Designer", "Active"],
    ]
))

Images & Links

from markdownpal.blocks import ImageBlock, LinkBlock

doc.append(ImageBlock(src="logo.png", alt="Project Logo"))
doc.append(LinkBlock(text="Documentation", url="https://example.com/docs"))

---

Inline Helpers

Inline helpers return plain strings and can be embedded inside any block content:

from markdownpal.inline import bold, italic, code, strikethrough

bold("important")            # **important**
italic("note")               # *note*
code("os.path.join()")       # `os.path.join()`
strikethrough("deprecated")  # ~~deprecated~~

# Composable
bold(italic("emphasis"))     # ***emphasis***

# Embed in blocks
doc.append(TextBlock(f"Call {code('render()')} to get the output string."))

---

Document API

doc = Document()
doc.append(block)   # Add a Block instance
doc.render()        # Returns the full Markdown string
doc.save("out.md")  # Writes UTF-8 Markdown file to disk

append() raises TypeError if the argument is not a Block instance.
render() joins all blocks with a blank line (\n\n) between them.
