((?!\.done))$ &nbsp; &nbsp; &nbsp; &nbsp;//this expression produces an error &quot;Infinite loop&quot;

((?!\.done))$        //this expression produces an error "Infinite loop"

<div>
This works for me... but negative operators can vary by regex interpreter<br />

<pre><code id="code-20-41940244-1">/^((?!\*\.Done)[\s\S])*$/gm</code></pre>

I need to have a 1 line expression that excludes patterns that include a specific pattern or substring.<br />

Not sure where to start:<br />
I have the following pattern &nbsp;<b>&quot;*.Done&quot;</b>, and I want an expression that excepts all patterns except this one.<br />

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
