I want to match strings containing MYSTUFF in all cases, except when MYSTUFF is preceded by ENABLED_. So that the following would match:
我希望在所有情况下都匹配包含MYSTUFF的字符串，除非MYSTUFF前面有ENABLED_。因此，以下内容将匹配:
MYSTUFF- MYSTUFF
m_MYSTUFF- m_MYSTUFF
MYSTUFFIsGreat- MYSTUFFIsGreat
allOf_MYSTUFF- allOf_MYSTUFF
but the following wouldn't:
但以下不会:
ENABLED_MYSTUFF- ENABLED_MYSTUFF
m_ENABLED_MYSTUFF- m_ENABLED_MYSTUFF
ENABLED_MYSTUFFIsGreat- ENABLED_MYSTUFFIsGreat
allOf_ENABLED_MYSTUFF- allOf_ENABLED_MYSTUFF
I tried several variations using negative lookahead (variations of \w*(?!.*ENABLED_)MYSTUFF\w*), and conditional (variations of (?(?!=ENABLED_)(MYSTUFF))), but I did not manage to get the results I'm after.
我尝试了几种不同的方法，使用消极的前视(w*(?!.*ENABLED_)MYSTUFF\w*)和有条件的(?(?)=ENABLED_ (MYSTUFF)))，但是我没有得到我想要的结果。
Is what I want even doable with regexes?
我想要的是regexes吗?

You could accomplish this by using a negative look-behind assertion ...
你可以通过消极的背后判断来实现这一点。
\w*(?<!ENABLED_)MYSTUFF\w*
