What version of Go are you using (go version)?

$ go version
go version go1.14.2 linux/amd64

Does this issue reproduce with the latest release?

This isn't an issue with the go core.

I did install the latest version of present with go get -u golang.org/x/tools/cmd/present2md

What did you do?

I ran the tool to convert some slides.

What did you expect to see?

For code blocks that are part of a list, Markdown requires that there be extra indentation. So for example with a top-level list, you need two levels of indentation for a code block (8 spaces or 2 tabs). For a second level list you need three levels of indentation, etc.

Alternatively, CommonMark supports fenced code blocks, which work without any indentation in all contexts.

What did you see instead?

All code blocks are output with just one level of indentation, meaning any code block in a list was no longer formatted correctly.

Rather than trying to get the indentation right, I'd suggest just outputting a fenced code block. This is a lot simpler to edit later since you never have to fiddle with the indentation.
