      You need an "R" in your options for regular expressions. "T" btw has no
      effect when "R" is used.

      Please address any followup or other clip questions to the clips list.

          I just tested and this works perfectly:

          ^!Replace "^Ak(\s)" >> "Ik$1" ATWSR
          ^!Replace "^\-Ak(\s)" >> "-Ik$1" ATWSR

          Specifically:
          Akbar
          Ak at the bar
          -Ak at the bar
          Rawr!

          Becomes:

          Akbar
          Ik at the bar
          -Ik at the bar
          Rawr!

          If you want the space character to be optional, you need to use this
          instead:
          ^!Replace "^Ak(\s)?" >> "Ik$1" ATWSR
          ^!Replace "^\-Ak(\s)?" >> "-Ik$1" ATWSR

            janderri,

            These are the same 2 lines posted previously, they worked after adding
            an 'R' to the settings and deleting the extra Tab in the first ^!Replace
            line. In the original email the first line had a Tab preceding the
            double chevron.

                  Just one more question, the regular expressions and replace commands are really clumsy laid out in the help file. For example : ^!Replace . Rik . RIk

                    Just one more question, the regular expressions and replace commands are really clumsy laid out in the help file.

                    For example : ^!Replace "\.\Rik" >> "\.\RIk" ATWR

                    Why doesn't this replace :

                    "
                    someline.
                    ik something here.
                    "

                    with :
                    "
                    someline.
                    Ik something here.
                    "

                    instead it does this (doesn't care about the regular expression \R which is newline)

                    "
                    someline.RIk something here.
                    "

                    Please how I can make it do a newline in the replacement command ?
                    TIA!

                        file format) is only active on the left side. If you want a linefeed
                        inserted in the replacement use "\r\n".

                        so: ^!Replace "\.\Rik" >> "\.\r\nIk" ATWR
                        also: "." only has special meaning on the find side (necessitating
                        escaping it as \.). On the replace side "." is just a regular character
                        so it doesn't need to be escaped.
                        hence: ^!Replace "\.\Rik" >> ".\r\nIk" ATWR

                          Actually I think the capitalization may be the issue. Even with ignore case - the case of the slash command matters. r matches ends of lines R matches

                            Actually I think the capitalization may be the issue. Even with
                            "ignore case" - the case of the slash command matters. \r matches ends
                            of lines \R matches everything EXCEPT ends of lines.

                            As for the other question on how to do ORs-

                            If it's only one letter, place it in a bracket:

                            ([ab]) matches a or b

                            If it's whole sequences place them in a (?: ... ) series (for each)
                            separated by a pipe (|)

                            So,

                            ((?:Clarissa)|(?:Claire)) matches "Clarissa" or "Claire" but nothing else.

                            --Keith

                              Hi Keith,

                              There are a few metacharacters that are like that (where the capital
                              version is opposite the lowercase version), but not true of "r".

                              Backslash-R is a metacharacter for:| "(?>\r\n|[\r\n])"|.

                              You can cause it to match: |"(?>\r\n|\n|\x0b|\f|\r|\x85)"

                              instead by including (*BSR_UNICODE) at the start of a pattern.|

                              Dot is what matches everything but line breaks (unless the ?s option is
                              used).

                              Backslash-R was not a metacharacter in PCRE versions earlier than 7.0.
                              It is only since PCRE 7.4 that there are alternative meanings for \R. In
                              7.0-7.3, it matched only the unicode version.

                              Regards,
                              Sheri

                                  As long as you are still using regular expressions, it's the answer I
                                  gave before. Namely:

                                  One-character ORs are done with a bracketed pair:
                                  [ab]
                                  Matches a or b

                                  Multiple-character ORs are done with a non-capturing group like so:
                                  (?:apple)|(?:bannanna)
                                  Matche apple or bannanna but not say applanna.

                                  In regards to your other question about the replace command and new
                                  lines, did it get answered with the prior responses or is it still
                                  outstanding?

                                      Isn't it more a matter of "style" to use non-capturing groups here
                                      than
                                      a demand of logical OR? I learned from Jeffrey Friedl that it's more
                                      a
                                      side effect of (?:) to save run time and memory (since the contents

                                      these brackets isn't stored). Maybe this has an effect with very big
                                      files.

                                      IMHO even the grouping is not essential. Also "apple|banana" would
                                      match here (or more precisely: "bannanna").

                                      To add to your examples: Also a simple question mark can make an OR,
                                      e.g. "Alfredo?" matches "Alfred" OR "Alfredo".

                                          There is definitely no requirement to make each alternative into a
                                          subpattern. If you choose to make them subpatterns, I would recommend
                                          making them non-capturing in NoteTab's present implementation. Among
                                          alternatives, only one choice will be set and all others unset.
                                          NoteTab currently has issues with unset substrings.

                                          But capturing multiple substrings where one or more will be unset is
                                          usually not desired anyway. If anything, you would usually want to
                                          retrieve the overall result among alternatives, which can be achieved
                                          by surrounding the whole group with parentheses: (apple|bandanna). If
                                          that were the whole pattern no parenthesized subpatterns would be
                                          needed because the result would be the whole match.

                                          Regards,
                                          Sheri

                                            Expressions I was using made the | evaluate only the letters beside
                                            the pipe. Thus in the example of apple|bannanna (whoops on my previous
                                            spelling btw) it would only match:

                                            appleannanna or applbannanna

                                            But, I just tested your post and it certainly (at least in this
                                            version of PCRE) works just as you describe woot!!

                                            Which IMO, looks a lot nicer.

                                            So am I correct that the following:

                                            Mary went to the store|market\.

                                            Would match:
                                            Mary went to the market.
                                            Mary went to the store.

                                            ??
