How to use the blocks feature?

[Enrico B. da Luz]

Hi, I noticed this in a recent update:

It also adds a new "blocks" feature for quoting
blocks of code, including an in-the-terminal
button to copy code to the pasteboard.

How do I use it? Can someone share more details?

Thanks!

Here’s some sample code:

https://github.com/gnachman/gptline/blob/main/src/highlight.py#L157

Here’s what it looks like:

The block is defined by the bar on the left side. The “copy to clipboard” link and button refer to its identifier. The main use of blocks is to simplify copying chunks of code to the clipboard. If you have ideas on what else it could do, let  me know!

Nice, thanks for that George!

For reference, I've managed to replicate this using bash, either I'm doing something wrong or it's copying the next line beyond the output:

#!/usr/bin/env bash

start_block() {
  block_id="$1"
  type="$2"
  echo -ne "\033]1337;Block=attr=start;id=$block_id;type=$type\a"
}

end_block() {
  block_id="$1"
  echo -ne "\033]1337;Block=attr=end;id=$block_id;render=0\a"
}

copyButton() {
  block_id="$1"
  echo -ne "\033]1337;Button=type=copy;block=$block_id\a"
}

block_id=$(uuidgen)
block_type='python'

content="print('$block_id')"

echo $(copyButton $block_id)
echo -n $(start_block $block_id $block_type)
echo $content
# With `-n` it will copy the next line (typically a PS1 / prompt)
# Without `-n` it won't copy the prompt but it will print an extra line
echo -n $(end_block $block_id)

In terms of ideas, it would be nice to be able to collapse blocks. Actually, that would be handy for the whole command output and maybe blocks could be collapsed as a sub-level.

The bug with selecting an extra line is fixed now.

I agree collapsing would be nice. That’s been in the todo list for a long time but it’s pretty difficult to get right.
