Thanks! I've now recreated the issue. Here's a smaller example:

import pe
p = pe.compile("[0-9] [ \t\n]* [0-9]", flags=pe.DEBUG)
p.match("1\n2")

(and due to some confusion in the use of compile-time vs parse-time flags, just doing pe.match(..., flags=pe.DEBUG) does not work; this may be a separate issue)

The output of the above is:

## Grammar ##
Start <- [0-9] [ \t\n]* [0-9]

1
2          |    [0-9] [ \t\n]* [0-9]
1
2          |      [0-9]

2           |      [ \t\n]*

2           |        [ \t\n]
2            |        [ \t\n]
2            |      [0-9]
<Match object; span=(0, 3), match='1 2'>

And I see that the problem is not the printout of the grammar rules but with the context on the left. I agree that this makes the output hard to read.
