The original, it seems to me, was looking for a "grep" output line,
of form
  file-name: found-line-content

I have similar macros to open a file from a grep output-line and position
the cursor on the line that grep found.

You want to double-up the backslash - when reading the string, the macro
language parser turns \s into s. (Note that \t, \n, \r, \a, \b, \e, \f, \v
are substituted with the tab, linefeed, carriage-return, bell, baskspace,
escape, formfeed, and vertical tab characters; \\ is substituted with a
single \.) So to get the regex to see "\s" you need to write your macro
string as "\\s".

The grep output lists the file-name followed by a colon, so the colon
becomes the delimiter there.
