Regular Expression Functions

Hey Chris,

I'm trying to use regexReplaceAll() to escape the pattern string to make it safe for use with regexSearch().

Unfortunately, I can't seem to make regexReplaceAll() function work.  I rather not use sustitute() function for each and every special characters in regular expression.

In function regexReplaceAll(), the replacement string doesn't seem to support the regular expression substitution syntax.  I need to be able dynamically escape special characters and I can't seem to be able to dynamically escape characters I'm escaping.

Let me know if there is a way to get it to work in using your library.  I'm trying to escape the usual suspects:

., +, *, ?, ^, $, (, ), [, ], {, }, |, \ (not including commas).

Also, I remember using the regular expression plugin twice in the last decade and I remember that version was more like the industry standard regular expression function behavior, similar to one implemented in Java.  Am I wrong?  Also, could it be possible to be more of a transparent call to how the regular expression works in Java?

Thanks.

I got it to work.  Here's an excerpt of my code in case anybody else is interested in escaping their regular expression pattern using regexReplaceAll() function.

local!escapedPatternList: a!forEach(
    items: local!patternList,
    expression: fn!regexreplaceall(
      "([+-.\*?^$\(\)\[\]\{\}\|\\])",
      fv!item,
      "\\$1"
    )
)
