           Summary: KReplace: Placeholder substitution for regular
                    expressions not implemented

            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: kdeui

Installed from:    Debian testing/unstable Packages

KReplaceDialog [1] allows for replacing text matched by a regular expressions with substituting content from the match using placeholders (\0, \1...). This can be set by giving option BackReference = 512.

KFindDialog implements widgets for setting this option in [2].

KReplace only implements placeholder \0 though, which means only substituting the whole match.

Currently extracting a partial match from the given regular expression is not supported.

I consider this a bug as this functionality is clearly wanted by the UI but not given by the underlying library. This feature is used in the KTextEdit widget.

See the Kate implementation on replacing using placeholders [4]. Maybe this can be merged into KReplace.
