perlquestion stefan k Fellow Monks, <p> I just ran into the problem of renaming a C++ class throughout many files. The class-name was in camel case (say TheClass) whereas the filenames were lower case (theclass.cc). The bundle came with a Makefile and naturally I wanted to replace the names in there, too. <p> The renaming of the files was done using <code>mmv</code>. <p> And for the contents of the files I wanted to use that favorite perl-one-liner: <code> perl -pi.bak -e 's/theclass/thenewclass/' </code> And, yes, I <em>could</em> have done this for every possible case, but I wondered whether all that could be done in one line. After reading <code>man perlre</code> and surfing the Monastery I finally found one solution at [id://307638]. <p> But, honestly, this can't be it, can it? <p> I'd appreciate a "I" modifier (or something like that) for regexeps that means "preserve case" very much like the (X)Emacs variable <code>case-replace</code> does it. It would match case insensitive but perform some magic to the replacement in that it would preserve the case of the matched pattern there. <p> I am well aware that this would be quite hard for replacements that have a different length from the search pattern. Still, even then the cases at some prominent positions (like the first or the last character or characters after a grouping construct, etc) could be figured out. <p> Is that possible or already existing, or already planned? Am I missing something here? <p> In expectation of deeper enlightenment and with many thanks... <div class="pmsig"> <div class="pmsig-5094"> <p> <table width="80%" border="0" cellspacing="0" cellpadding="0"> <tr> <td><small>Regards...</small></td> <td align="right"><small> <a href="http://www.skamphausen.de">Stefan</a> </small></td> </tr> <tr> <td colspan="2" align="center"> <small>you begin bashing the string with a +42 regexp of confusion</small> </td> </tr> </table> </div></div>
