UNWRAPDIFF(1)                                                    UNWRAPDIFF(1)




NAME

       unwrapdiff - demangle word-wrapped patches


SYNOPSIS

       unwrapdiff [-v] [file...]

       unwrapdiff {--help | --version}



DESCRIPTION

       unwrapdiff demangles patches that have been word-wrapped, in an attempt
       to make them useful.


       The corrected diff is sent to standard output. Note that you will prob-
       ably need to use the -l option when applying the patch, in order to ig-
       nore any whitespace differences there may be.



OPTIONS

       -v     Verbose operation. A list of lines that are modified  in  a  way
              that might be wrong is sent to stderr.


       --help Display a short usage message.


       --version
              Display the version number of unwrapdiff.



LIMITATIONS

       Some  heuristics  are used to decide whether use a space to recombine a
       wrapped line, or just join them together. Currently  this  is  done  by
       comparing with last three characters of a line with the first two char-
       acters of its continuation, and using a space of any of them  are  dif-
       ferent.


       The patch needs to have been valid before being word-wrapped.


       The  last  line  of a hunk is nearly always ambiguous. If the next line
       begins ‘‘@@’’, ‘‘Index: ’’, ‘‘diff ’’ or ‘‘--- ’’ then it is  taken  to
       be complete; otherwise it is unwrapped using the next line.
