    UltraEdit 2022.1.0.100 64-bit

    I'm rewriting some code that Mofi helped me with many years ago. (Really delighted that's he's still helping us novices along. Great!)

    !´ve got used to testing all my regex code in RegexBuddy nowadays - it's a real help, I use it regularly. I can thoroughly recommend it. (Except: it has no converter for the UE flavor.)
    The following regex works just fine in RegexBuddy:

    RegexBuddy (latest version) set for "Perl 5.30-532")

    FIND STRING:

    Code: Select all

    (?P<FNplaceholder><<--1)-->>(?P<mainText>\p{Any}*?)(?P<footnote>\[1*\N.*)
    REPLACE STRING:

    Code: Select all

    $+{FNplaceholder}$+{footnote}>>$+{mainText}
    Using the "convert to java string" converter inside RegexBuddy hence produces:

    Code: Select all

    "(?P<FNplaceholder><<--1)-->>(?P<mainText>\\p{Any}*?)(?P<footnote>\\[1*\\N.*)","$+{FNplaceholder}$+{footnote}>>$+{mainText}"
    In RegexBuddy this regex works just fine. Here's what it does. It takes a text like the one below and does the following: it replaces the footnote placeholders in the main text (marked by <<--x-->> ) with the footnotes in the footnote block, at the end of the text, which start with "[x] footnote footnote<CR>"  But if I put this regex inside this UE script (which I think Mofi once wrote for me) it doesn't work.

    What am I doing wrong?
    (Once this regex is up and running, I will want to put it inside that "WHILE" loop, so that it iterates through all of the place markers in the text "<<--x-->>") (Which means my next problem is: how to turn that "1" into a variable.)

    (If it's not too expensive I'd be quite happy to join the VIP+ club.)
    Very best, and most grateful for help ...

      Hi,

      this Perl Replace All replaces all footnotes at once. But preserves the list of footnotes at the end of file so you have to delete them separately.
      F: <<--(?<FNnum>\d+)-->>(?=(?s:.*?)(?<footnote>^\[\k<FNnum>\].*))
      R: <<--$+{footnote}>>

      or if you really wish to keep the placeholder number. Or tailor the replace string as you need.
      R: <<--$+{FNnum}$+{footnote}>>

      Tested on your sample in UE 2022.1.0.108 x64

        Thank you very much indeed. I'll need some time to try all this out. Much appreciated!

          Sep 24, 2022#4

          @fleggy:
          This is working like a charm. What I've learnt from you:

          a) How to use the "positive lookahead" (?=)
          b) How to use the "dot matches line breaks" ?s: instead of  p{Any}
          c) That the \k really works like a variable, enabling a loop.

          I'm discovering also that simply running this in RegexBuddy has the advantage that it gives you a full log of all find/replace operations, enabling you to check to see that everything is working. (In addition to getting a full debug and documentation of all the commands used. This novice really needs that, learns from it.)

          As a mark of appreciation, I've become a VIP+ user, putting something into PayPal. Thanks again!

            I'm still having problems in getting a regex to work in a UE script. Take the following.
            A common task in DTP (Desktop Publishing) is the identification of footnote placeholders. (Think of a docx file, containing footnotes, that's just been converted to TXT.) So, the task is to identify the sequence of footnotes starting with 1, render them unique (by turning them into <<--x-->>), while ignoring all the other digits in the text. So, with RegexBuddy, I first of all did some preliminary sorting, with:

            Code: Select all

            (?<!Chapter )(?<![ |`|.])\d+(?=[ |\)])
            Footnote placeholders:
            must precede either a blank or a ")"
            must NOT follow on a blank or a tilde ` (The latter can then be used as an escape character.)

            But this script of mine isn't working at all - I'm doing something wrong. (Nothing happens, no error messages.)
            I'd be really grateful for a helping hand.
            (The last line is an acknowledgement that this is a script that Mofi helped me with many years ago!)

            Areas where I'm unsure:
                            var counter == counter++ ;
            Those double backslashes which UE scripts needs in the regex.

            Code: Select all

            //////20220925/////// find footnote placeholders in text //////////////////////////////

              Hi,

              just two things:
              1) do not use "|" as an OR in a character class. Simply put all required characters/intervals inside []. For example [ `\.]
              2) I do not understand why you use a script when Replace All should be enough.
              and 3) :) I have zero DTP skills and knowledge yet it seems to me that your pattern (?<!Chapter )(?<![ `\.])\d+(?=[ \)]) finds many false positives.

                Thank you for the help.
                I'm trying to write a regex (or a script/regex combination) that will replace the sequence: 1 2 3 4 .... 999 with <<--1-->> <<--2-->> <<--3-->> <<--4-->> <<--999-->>  (In the test text above.)
                In the good old emacs days, you could load the digit at the cursor position into a variable and let loose some if/then conditionals. If there's a workaround for this in a regex flavour out there, I'd be most interested. (I saw somewhere that JavaScript regex is starting to implement variables.)
                So for the moment, until I get more clued-up, the script has to do it: "if the current match is  1, then the next match needs to be 2 "
                (Thanks for the tip: the alternative "|" inside a [...] is superfluous.)
                For the moment, this regex is just a first filter:

                Code: Select all

                (?<![ `.])\d+(?=[ )])
                - and then the script figures out if the next match fits the sequence 1 2 3 4 ... 999  (I'd be interested to learn how to get rid of more of the false positives using the regex though...)
                Regards!

                  well, considering all mentioned rules this Perl regexp matches whole numbers

                  (?<!Chapter )(?<![ `.\d])\d+(?=[ )])

                  I added \d to the negative lookbehind to eliminate false positives like 59 in 1.359.
                  I don't use scripts so I can't help you with it, sorry...

                    Thank you very much.  I'm most obliged! I've learnt a lot. Here, for completeness, are the two regexes that you've helped me develop. They're now fully functional in RegexBuddy - i.e. I'm actually using them - though I haven't got them to work in a UE script yet.  Works like a charm!

[5] Der Text der französischen Verfassung vom September 1791 beginnt mit einem Katalog, der zwischen droits naturels und droits civils unterscheidet. Damit hat er der zeitlichen Diskrepanz Rechnung getragen, die zwischen dem aktuellen Geltungsbereich der allgemeinen Staatsbürgerrechte und dem noch nicht realisierten, weit über die terri-torialen Grenzen des französischen Staates hinausweisenden Geltungsanspruch der »na-türlichen«, allen Personen dank ihres Menschseins gleichermaßen zustehenden Rechte besteht. Paradoxerweise behalten aber die als Grundrechte positivierten Menschen- und Bürgerrechte auch innerhalb der nationalen Grenzen den Sinn universaler Rechte und erinnern auf diese Weise die lebenden und die künftigen Generationen, wenn schon nicht an eine Selbstverpflichtung zur aktiven Verbreitung dieser Rechte, so doch an die Eigentümlichkeit des normativ überschießenden Gehalts von universalen Menschen-rechten über den provisorischen Charakter ihrer einstweilen territorial eingeschränkten Inkraftsetzung hinaus. Der moralische Überschuss hinterlässt auch in den geltenden Grundrechten Spuren eines noch nicht abgegoltenen normativen Gehalts; diese verraten etwas vom beunruhigenden Charakter einer ungesättigten Norm. Die fehlende »Sättigung« betrifft die zeitliche Dimension einer im politischen Gemeinwesen noch ausstehenden und in sachlicher Hinsicht noch zu spezifizierenden Ausschöpfung des unbestimmt überschießenden Gehalts etablierter Grundrechte ebenso wie die räumliche Dimension einer noch ausstehenden weltweiten Implementierung von Menschenrechten.

Seeliger, Martin; Sevignani, Sebastian »Zum Verhältnis von Öffentlichkeit und Demokratie«, in diesem Band, S. 11, spezifiziert diese Rolle unter Gesichtspunkten der Transparenz öffentlicher Angelegenheiten, der allgemeinen Orientierung der Bürger und der reziproken Rechtfertigung von Themen und Beiträgen.
[10] Normativ betrachtet, erfüllt die sogenannte Output-Legitimität eines Regierungshandelns, das die Bürger bei Laune hält, nicht die Bedingungen demokratisch legitimen Handelns; denn solche staatlichen Leistungen decken sich zwar mit Interessen der Bürger, ohne diese aber in Ausführung eines demokratisch gebildeten Willens der Bürger selbst zu befriedigen.
