Code blocks

Slides allows you to execute code blocks directly inside your slides!

Just press ctrl+e and the result of the code block will be displayed as virtual text in your slides.

Currently supported languages:

  • bash
  • zsh
  • fish
  • elixir
  • go
  • javascript
  • python
  • ruby
  • perl
  • rust
  • java
  • cpp

Go

Use /// to hide verbose code but still allow the ability to execute it.

If you press y to copy (yank) this code block it will return the full snippet.

And, if you press ctrl+e it will run the program without error, even though what is being displayed is not a valid go program because we have commented out some boilerplate to focus on the important parts.
