The result will contain a few empty lines, but I'm sure, you can solve that. The \n at the beginning of the substitution is needed for a formatting issue The ? (= optional) match won't give you an error if there aren't enough matches for all substitutions. You have to copy this regex as often as needed to match all lines (i.e. (\1: ( *))? = optional matches on consecutive lines, belonging to the same group. ^( ): ( *) = matches on the first line of a group The problem with the substitution is the uncertain number of matches. Keeping the remainder of the rows aligned is, of course, sugar on the cake… If you know better, please, point me into the right direction. On the other hand, I might just not be able to come up with the right question to search the net for. I wonder, whether there is an elegant (say: one search pattern, one replacement, run once) solution at all. How to merge lines that start with the same items in a text file Not sure, it's going into the right direction anyway, though. Is rejected for the lookbehind not being fixed length. Gets me anywhere close to what I'm looking for. Matches correctly, neither the replacement There could be up to about a dozen (and a half) lines starting with the identical sequence of characters. If consecutive lines start with the same sequence of characters up to / including some separator (here the colon (and the blank following it)), only the first instance should be preserved - as should be the remainder of all lines. ![]() › Scala how to get class of mixin compositionĬd: asdf, asdfas dfasdfa,asdfasdfa,afdsfa sdf › Error at createindex elasticsearch using elasticsearchoperations why is the quotbytesreference class was expectedquot exception happening › Scala object private scope with inner classes and methods › Bootstrap use css class at breakpoint xs md › Androidviewsinflateexception binary xml file line 1 error inflating class toolbar › In python any way to automatically run functions as soon as a class is defined › Could not find or load main class org gradle wrapper gradlewrappermain › How to setup learning environment for udacity deep learning class with tensorflo › How to save training history on every epoch in keras › Reflecting a private field from a base class › Printing attributes of objects in a class in python ![]() › Cannot construct instance of class name although at least on creator exists › Java return only attributes of superclass › If a subclass refers to a superclass ivar synthesizing an unrelated property fa › Can i declare class object globally in c › Android studio 3 0 canary 5 errorunable to load class org gradle api interna › Python class variable update based on dictionary › Add a css class to single code chunks in rmarkdown › How can i determine a class39s superclass at runtime › Hibernate java lang classcastexception org hibernate action entityidentityinser › C how to convert listdog to listanimal when dog is a subclass of animal › How to generate typescript uml class diagrams › Why is a character class faster than alternation › How to find and remove unused class files from a project ![]() › Adding class files to an eclipse project › Classcastexception javamathbiginteger cannot be cast to javalanglong on connect to mysql › Change class of multiple columns in data frame without for loop › Dynamically converting java object of object class to a given class when class name is known › Is it pythonic to use init py modules of a package for generic abstract classes › Modelmapper choose mapping based on child class ![]() › Python course 2022 session 3 functions unmanned aerial › Attempted to load class classname from namespace even though namespace
