I want to replace all occurrences of abc in my string to xyz as below:

The following must be replacd with xyz:

abc with space in either side ,abc abc, abc; abc.

But the following must be left unchanged:

abc as part of any other word like aabcd or abcdef abchaving _ after or before it like abc_ or _abc

I tried the following codes but didn't work out:

string.gsub(str,'%W'.."abc"..'%W', "xyz")

string.gsub(str,'[ ,]'.."abc"..'[ ,.;]', "xyz")

is t possible to do so in lua? May you please guide me? regards

`string.gsub(str, "%f[%w]".."abc".."%f[%W]", "xyz")` – Egor Skriptunoff Nov 27 '16 at 07:44
@EgorSkriptunoff thank you, you've put me in right direction :) – Majid NK Nov 27 '16 at 08:09
Sorry, it should be `string.gsub(str, "%f[%w_]".."abc".."%f[^%w_]", "xyz")` to work correctly with underscores. – Egor Skriptunoff Nov 27 '16 at 11:53
