Eval code by sending it via stdin (Pipe)

[tionis]

I am currently experiencing issues that I believe come from my use of quotes in the source, I would propose the following changes so that complex quote handling won't be needed:

• Allow specifying that a command reads the {{src}} from stdin (like it's solved in https://github.com/gpanders/vim-medieval).
• As this is exactly how scripts are interpreted normally most tools should support it, and it completely forgoes most issues regarding quoting

I don't have time to implement that, but definitely, it makes sense.

I have this problem too. I found it easily solved using heredoc. For example

"template": "/opt/homebrew/bin/lua <<EOF\n{{src}}\nEOF"
