Unrecognized escape sequence \_

v1ktor — Sat, 09 May 2020 16:03:46 GMT

Not sure if it's a bug or by design, I thought I report it just in case.

I was adding a filter with regex enabled but LogViewPlus threw an error because I escaped underscores. I know I don't have to escape them, but it shouldn't be a problem regardless. Here's a screenshot (I couldn't upload an image here, it kept inserting broken image).

Thanks for reporting this issue. Not sure why you had upload problems. For future reference, your screenshot image is:

LogViewPlus parses regular expressions using the standard Microsoft .Net library. This library supports a limited set of predefined escape characters discussed here:
https://docs.microsoft.com/en-us/dotnet/standard/base-types/character-escapes-in-regular-expressions

As you have already discovered - it is not necessary to escape the underscore character.

Hope that helps,

Toby
