Inside of our document we wish to define a new environment for blocks of source code

newenvironment{srcblock}%

  % Define the environment

Later, we will use the environment:

begin{srcblock} % use the environment

  % source code here

end{srcblock}

We seek the following behavior:

• Each line in a src code block is numbered


• The font used for a src code block is monospaced


• A border is drawn around a code code block, much like fbox does


• Each code block "floats" to a position so that it will fit all on one page.

Variation on my answer here: Seemingly trivial: verbatim, newenvironment, and colorbox. It requires a small modification to my verbatimbox package.

This approach is not a simple environment but a standard minted environment nested in you own float environment. Not exactly the asked but:

☑ Each line in a src code block is numbered (optionally)

☑ The font used for a src code block is monospaced (and syntax highlited)

☑ A border is drawn around a code code block, much like fbox does (with top caption inside using stdcaption, for a botom caption outside the box use caption*)

☑ Each code block "floats" to a position (concretely to top of a new page) so that it will fit all on one page.
