From d9b1d57351d104d7ec1a5621f090657dcce8cb7f Mon Sep 17 00:00:00 2001 From: Jon Steinhart Date: Wed, 7 Dec 2005 21:25:46 +0000 Subject: [PATCH] Fixed a bug where anno -append put the headers in the wrong place if applied to a message that didn't contain any headers. Added a special value of "all" to the -number option that causes anno -delete to delete all matching components instead of just the first one. Added new -preserve and -nopreserve options. Using -preserve retains the original last accessed and last modified times on annotated messages. --- h/prototypes.h | 1 + man/anno.man | 20 +++++++++++++- uip/anno.c | 25 +++++++++++++++--- uip/annosbr.c | 79 ++++++++++++++++++++++++++++++++++++++++++++------------ 4 files changed, 104 insertions(+), 21 deletions(-) diff --git a/h/prototypes.h b/h/prototypes.h index 21c15a7..fe41962 100644 --- a/h/prototypes.h +++ b/h/prototypes.h @@ -159,6 +159,7 @@ char *OfficialName(char *); */ int annotate (char *, char *, char *, int, int, int, int); void annolist(char *, char *, char *, int); +void annopreserve(int); int distout (char *, char *, char *); void replout (FILE *, char *, char *, struct msgs *, int, int, char *, char *, char *); diff --git a/man/anno.man b/man/anno.man index b626e2a..e2a77c1 100644 --- a/man/anno.man +++ b/man/anno.man @@ -20,7 +20,8 @@ anno \- annotate messages .RB [ \-list ] .RB [ \-delete ] .RB [ \-number -.IR [ num ]] +.IR [ num|all ]] +.RB [ \-preserve " | " \-nopreserve ] .RB [ \-version ] .RB [ \-help ] .RB [ \-text @@ -133,6 +134,23 @@ whose name matches the component is deleted.
