But either way, all of these are, indeed, syntax errors and need to be
corrected. (It turns out, just looking at the first example on line
1236, that they cannot all be fixed by turning them into raw strings:
this string has both '\p', which should be '\\p' (with a literal
backslash), and '\n', which presumably is intended as a new line
character.
Oh, and just to add on to this: I believe that this will become a
SyntaxError in Python 3.13 or Python 3.14.
Ok, thanks for clarifying!
I was able to reproduce the warnings in Python 3.12:
$ python3.12
Python 3.12.2 (main, Mar 3 2024, 09:11:00) [GCC 13.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
import dot2tex
/usr/lib/python3/dist-packages/dot2tex/dot2tex.py:900: SyntaxWarning: invalid
escape sequence '\i'
variables['<>'] = "\input{gvcols.tex}"
/usr/lib/python3/dist-packages/dot2tex/dot2tex.py:1236: SyntaxWarning: invalid
escape sequence '\p'
...
They were silent using Python 3.11, which is suppose is why I hadn't seen them
before.
