Examples

Decorated blocks.

Code blocks in several languages, each labelled by the extension as this page renders.

Warning

This extension is superseded by Code Window.

Every block below is labelled by the extension as this page is rendered.

Note

This site runs only this extension, and not the code-window filter the other sites in the family use. Both decorate code blocks, so running the two together would make it impossible to tell which decoration came from which.

One block per language

MARKDOWN

```r
summary(cars)
```

R

summary(cars)

PYTHON

print(sum(range(10)))

BASH

find . -name '*.qmd' -print

YAML

filters:
  - language-cell-decorator

Each carries the language Quarto recorded on it, and nothing was written on the blocks themselves.

A block with no language

MARKDOWN

```
Plain text, with no language.
```

Plain text, with no language.

There is no language to show, so the block is left alone.

A filename as well as the language

MARKDOWN

```{.r filename="analysis.R"}
summary(cars)
```

R

analysis.R

summary(cars)

filename is Quarto’s own attribute. The filter adds its label to the one Quarto drew, so the block carries both, language first.

What Code Window does with the same blocks

Code Window shows the language by default, so these blocks look the same there without any configuration, and it adds window chrome and per-block styling besides.

Every other site in this family renders its code blocks through it; this one does not, so that the decoration above is unambiguously this extension’s.
