Code blocks#

Fenced code blocks are highlighted at build time by Pygments. Every block gets a copy button; no JavaScript highlighter is shipped.

def greet(name: str) -> str:
    return f"Hello, {name}!"

File names#

Add title="…" after the language to show a file name above the code:

```toml title="pyproject.toml"
[project]
name = "my-docs"
dependencies = ["mkdocs-sumi"]
```

pyproject.toml

[project]
name = "my-docs"
dependencies = ["mkdocs-sumi"]

Line numbers and highlighted lines#

These options come from Python-Markdown's codehilite, or from pymdownx.highlight if you use it:

```python hl_lines="2 3"
def total(items):
    subtotal = sum(i.price for i in items)
    return subtotal * 1.2
```

def total(items):
    subtotal = sum(i.price for i in items)
    return subtotal * 1.2

To show line numbers on every block, configure the extension:

mkdocs.yml

markdown_extensions:
  - codehilite:
      linenums: true

Shell sessions#

Use console for transcripts with prompts and output. The copy button then copies only the commands — without the $ prompts and without the output.

$ mkdocs build
INFO    -  Building documentation to directory: site
INFO    -  Documentation built in 0.42 seconds

Diffs#

 theme:
-  name: mkdocs
+  name: sumi

Inline code#

Write inline code with single backticks: mkdocs serve. In prose, Sumi gives inline code a quiet background that works in light and dark mode.
