I'm trying to replace a forward slash to back slash using gsub but can't get it to work.
gsub => ["message", "/", "\\"]
gsub => ["message", "/", "\"]
The above fails with a parse error.
gsub => ["message", "[/]", "[\\]"]
does the wrong thing by adding the brackets in the substituted string.
Any pointers would be appreciated.
Hi, you need a very tricky substitution
The only way of achieving it that comes to my mind is to use ruby code directly:
code => ' event.set("message", event.get("message").gsub("/", "\\") ) '
Be aware that if your output representation escapes special characters (for example Json), you'll see "doubled" backquotes in the result.
I add a link to a message with a related issue to have as reference and another unresolved one that might benefit from this.
That's exactly what I resorted to after many tries. I figured I was doing something wrong as replacing forward slash with backslash is a seemingly simple requirement.
