Remove or rename Listing caption

[vfacta]

Considering the following code block in a .qmd file:

```{.python filename="helllo.py" }
print("hello, world!")
```

It is converted in Latex's pdf output to something like this:

Listing 1 helllo.py

print("hello, world!")

I have already tried including in header the following commands, but nothing changed:

\usepackage{listings}
\renewcommand{\lstlistingname}{}

Here is a minimal working example:

---
title: "Untitled"
format: 
    pdf:
      include-in-header: 
        text: |
          \usepackage{caption}
          \usepackage{listings}
          \renewcommand{\lstlistingname}{}
---

```{.python filename="helllo.py"}
print("hello, world!")
```

How can I rename the listing caption or remove it entirely with its number?

Could you share a small "working" (reproducible) example to work with, i.e., a complete Quarto document or a Git repository? Thanks.

You can share a Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).

````qmd
---
title: "Reproducible Quarto Document"
format: html
---

This is a reproducible Quarto document using `format: html`.
It is written in Markdown and contains embedded R code.
When you run the code, it will produce a plot.

```{r}
plot(cars)
```

The end.

sure, just updated the post

Update: Following intructions from Quarto cross-references doc, I managed to remove the name "Listing" adding an empty string '' to lst-title in crossref:

crossref:
  lst-title: ''

However, it doesn't seem to be an option for removing the listing's number

Just to be sure - you are looking to only have hello.py shown in the box header above the code ? and remove "Listing 1" ?,

[vfacta]

Yes, that's the idea

Unfortunatly I don't think you can do that. Those environment are numbered by definition, and I don't think you can unnumbered them. You could try not use the listing feature but another LaTeX tools that allows you to create a box with a caption and that you can tweak how you like it

You might need to use LaTeX partials here, see https://quarto.org/docs/journals/templates.html#latex-partials.
In particular, the whole template.tex (it's where listings LaTeX package is imported, thus why your command did not change anything).
