[SOLVED] Match all instances of a character preceded by '/'

Match all instances of a character preceded by '/'

for example, I might have the string

/zombie nimble zombie quick
Plants vs Zombies reference

and I want to match every 'e' but only from the phrase "zombie nimble zombie quick", as it is preceded by a forward slash.

I can get the contents of the string preceded by the forward slash fairly easily with \/.*.
I can also match the first instance of 'e' in the correct string with \/.*?\Ke

But I want to match every instance of 'e' in the correct string in a way that's friendly for VSCode syntax highlighting, which afaik is the .NET flavour

Solution

If you are using PCRE, you may try the following regex:

^(?!\/).*(*SKIP)(*F)|e

^(?!\/).* a line doesn't start with a /
(*SKIP)(*F) skips the consumed text so far, which is the entire line
| or
e matches e, if the e didn't get skipped, means it's inside a line that starts with /

See the test cases

Edit

Thanks for Jan's advice.

If the / doen't always start from the beginning of a line, you may try

^[^\/]*(*SKIP)(*F)|e
