| The following code:
addxml.trigger { match = "^(.*?) looks very uncomfortable\.$",
regexp = true,
sequence = 50,
enabled = false,
omit_from_output = false,
name = key,
script = "Process_Study_Message",
group="study_triggers"
}
Produces this error:
Compile error
Plugin: Miniwindow_Plugin (called from world: Aardwolf)
Immediate execution
[string "Plugin"]:249: invalid escape sequence near '"^(.*?) looks very uncomfortable'
Error context in script:
249*: addxml.trigger { match = "^(.*?) looks very uncomfortable\.$",
250 : regexp = true,
251 : sequence = 50,
252 : enabled = false,
253 : omit_from_output = false,
I know since the latest version of Mushclient it has been much more picky about regex errors, but for the life of me I can't figure out what the issue is here. It is actually an exact copy from a trigger that was created by convert to regex option.

The Aardwolf MUSHclient Package uses Lua 5.2 semantics now, and Lua 5.2 strictly rejects invalid string escape sequences whereas 5.1.4 just used the literal follower.
To fix your pattern you need to change that \. to \\. because \. is not a valid string escape sequence. Keep in mind that your pattern is a string first and only becomes a regular expression after initial parsing. Even though you weren't getting an error before, I'm pretty sure it wasn't giving you quite the regex pattern you expected. |

| Alternatively, use longstrings, which don't have escape sequences.
[[^(.*?) looks very uncomfortable\.$]]

Which isn't officially supported by MUSHclient.
There have been so many changes to Lua 5.2, including incompatibilities with existing DLLs that I have chosen to stay away from it.
I thought when I saw that string that perhaps the backslash should be double-escaped, but since I couldn't reproduce it, I didn't say that. |

I try telling people to come to me first because of this, but they don't always listen. Sorry about the spillover. |
