Description Jerry James 2023-07-06 14:57:52 UTC

Create a trivial asciidoc document, say test.txt, with these contents:

= Document Header

This is a trivial AsciiDoc document.

Then run "asciidoc test.txt" in Rawhide.  You will see:

<unknown>:1: SyntaxWarning: invalid escape sequence '\S'

I have tracked the issue down to asciidoc/asciidoc.py, line 2911:

self.separator = ast.literal_eval('"' + self.separator + '"')

The issue is that self.separator can be an escape sequence, so the code should include an 'r' to ask for evaluation of a raw string; i.e.,

self.separator = ast.literal_eval('r"' + self.separator + '"')

The '\S' in question comes from asciidoc's own configuration files, by the way.

Reproducible: Always

Steps to Reproduce:
1. See above
2.
3.
Actual Results:  
Warning about an invalid escape sequence while asciidoc reads its configuration files.

Expected Results:  
No warnings.
