Parse exception when using %

[jonthansen]

Describe the bug:

Using a percent sign (%) anywhere in the prompt produces a parse exception. It appears related to a (new?) wrap command. I cannot find any documentation for the wrap command and this exception now prevents any other extensions or scripts from using the percent sign without breaking Dynamic Prompts. This has always been the case for the dollar sign ($).

Local Install, Version 2.17.1 of the WebUI extension, dynamicprompts library Version 0.31.0

Expected behavior:

Parsing of percent and dollar signs not conforming to Dynamic Prompts syntax should be handled gracefully, leaving them in place, and allowing Dynamic Prompts to continue without the exception

Please show the prompt you're using.

You're right the wrap command is new; it's documented here.

Some prompts where the percent sign or dollar sign produce an error:

# A percent sign as part of prompt text
a sign with text 100% FREE

# A dollar sign as part of prompt text
a sign with text You pay $0

# A line from a wildcard file using Umi-AI syntax that snuck into my wildercards folder
{20%::blue|30%::green|red} car

# A Prompt Fusion extension variable
$haircolor=ash-brown
a man with $haircolor hair

# A Useless Useful Variables extension variable
%eyecolor=amber%
a woman with %eyecolor% eyes

# A percent sign as a modulo operator in an Unprompted extensions expression
[if "var % 2 == 0"]I'm even![/if]

What I am hoping for is that these symbols can be ignored by Dynamic Prompts if they are not part of the Dynamic Pormpts syntax. For my own use I got around the problem by adding a few lines before and after the parsing of the prompt:

import re
# BEFORE PARSE
newprompt = ''
offset = 0
# regex finds these four possible parts:
# 1: Matches variation Combinations syntax: {#-#$$,$$
# 2: Matches everything inside %{} when $$ exists (TODO: learn wrap syntax then update to handle properly)
# 3: Matches ${
# 4: Matches %{
# Even index contains substring NOT matching the regex, replace $ and % with placeholders
for index, match in enumerate(re.split(r"({[\d-]+\$\$(?:.+\$\$)?|%{.*\$\$(?:.*\$\$)*}|\${|%{)", prompt)):
  if index%2 == 0:
    newprompt = newprompt + match.replace('$', '<dp_dollar_sign>').replace('%', '<dp_percent_sign>')
  else:
    newprompt = newprompt + match
  offset += len(match)

prompt = newprompt

#AFTER PARSE
prompt = prompt.replace('<dp_dollar_sign>', '$').replace('<dp_percent_sign>', '%')
