NAME

chbar - modify a context diff to add change bars

        before running patch

SYNOPSIS

changebar OLDFILE NEWFILE

FUNCTION

Installs ".mc |^G" as part of the first line of a changed-line region and is part of the first line of a region of added-lines as indicated by a context diff

        (diff -c oldfile newfile).

Also installs "^G.mc" as part of the last line of a changed-line region, and as part of the last line of an added-line region. This fools the patch program into believing that these characters are part of the patch to be installed to create the new file. Following running patch, a filter must be run to change the Control-G characters into line feeds; results in placing the ".mc |" on a separate line ahead of the changed region and the ".mc" on a separate line just following the end of the changed region, thus causing the region to be marked.

LIMITATIONS

See LIMITATIONS in the man-page that describes ``changebar''.
