Split-pane editing

[Hendrik Boom]

When editing code in emacs, I oftern split the pane so I have views on two parts of a
file.
Typically, this is so I can see a function definition in one pane at the same time as I
see a corresponding function application in another pane.
Sometimes, this escalates to three panes.

Is there any way to do something similar in drracket?

in DrRacket you can hit View|Split, and you can split multiple times.

I have recently been trying to do this too, as it looks like DrRacket *should* allow this…

That’s true, but that doesn’t seem to result in the same behavior as emacs, where it is possible to view two different files side-by-side, rather than one file of definitions in one pane, and the ‘interactions’ in the other pane. I can hide the interactions, but then I seem to have two panes which can only display the same functions and which scroll together, making even looking at two different functions in the same file, impossible (AFAICT).

It’s definitely possible to view two portions of a file side by side, using View > Split. See the screenshot below. But it doesn’t seem to be possible to view two different files side by side. Nonetheless, it should be straightforward to create a DrRacket extension to do that.

The OP was about splitting the same file. And in DrRacket, you can scroll the two panes independently.

If you want to look at 2 different files, a workaround is to open 2 DrRacket windows and put them side by side.
