This patch adds support for notmuch show --only-matching-messages which limits the output to only the top level messages matching the search terms provides.
Example: $ notmuch search subject:git AND thread:23d99d0f364f93e90e15df8b42eddb5b thread:23d99d0f364f93e90e15df8b42eddb5b July 31 [4/12] Johan Herland; [RFCv2 00/12] Foreign VCS helper program for CVS repositories (inbox unread) Note that in this thread 4 out of 12 messages matched. The default show behaviour is to show all messages in the thread: $ notmuch show subject:git AND thread:23d99d0f364f93e90e15df8b42eddb5b | grep 'message{' | wc -l 12 With the --only-matching-messages option the output is limited to the matching messages only: $ notmuch show --only-matching-messages subject:git AND thread:23d99d0f364f93e90e15df8b42eddb5b | grep 'message{' | wc -l 4 Signed-off-by: Bart Trojanowski <bart at jukie.net> --- notmuch-show.c | 48 +++++++++++++++++++++++++++++++++++++----------- notmuch.c | 7 +++++++ 2 files changed, 44 insertions(+), 11 deletions(-) diff --git a/notmuch-show.c b/notmuch-show.c index edebaca..8599c6c 100644 --- a/notmuch-show.c +++ b/notmuch-show.c @@ -211,6 +211,24 @@ notmuch_show_command (void *ctx, unused (int argc), unused (char *argv[])) notmuch_thread_t *thread; notmuch_messages_t *messages; char *query_string; + int only_matching = 0; + int i; + + for (i = 0; i < argc && argv[i][0] == '-'; i++) { + if (strcmp (argv[i], "--") == 0) { + i++; + break; + } + if (strcmp(argv[i], "--only-matching-messages") == 0) { + only_matching = 1; + } else { + fprintf (stderr, "Unrecognized option: %s\n", argv[i]); + return 1; + } + } + + argc -= i; + argv += i; config = notmuch_config_open (ctx, NULL, NULL); if (config == NULL) @@ -238,21 +256,29 @@ notmuch_show_command (void *ctx, unused (int argc), unused (char *argv[])) return 1; } - for (threads = notmuch_query_search_threads (query); - notmuch_threads_has_more (threads); - notmuch_threads_advance (threads)) - { - thread = notmuch_threads_get (threads); + if (only_matching) { + messages = notmuch_query_search_messages (query); + if (messages == NULL) + INTERNAL_ERROR ("No messages.\n"); + show_messages (ctx, messages, 0); - messages = notmuch_thread_get_toplevel_messages (thread); + } else { + for (threads = notmuch_query_search_threads (query); + notmuch_threads_has_more (threads); + notmuch_threads_advance (threads)) + { + thread = notmuch_threads_get (threads); - if (messages == NULL) - INTERNAL_ERROR ("Thread %s has no toplevel messages.\n", - notmuch_thread_get_thread_id (thread)); + messages = notmuch_thread_get_toplevel_messages (thread); - show_messages (ctx, messages, 0); + if (messages == NULL) + INTERNAL_ERROR ("Thread %s has no toplevel messages.\n", + notmuch_thread_get_thread_id (thread)); + + show_messages (ctx, messages, 0); - notmuch_thread_destroy (thread); + notmuch_thread_destroy (thread); + } } notmuch_query_destroy (query); diff --git a/notmuch.c b/notmuch.c index f45b692..a817ae3 100644 --- a/notmuch.c +++ b/notmuch.c @@ -177,6 +177,13 @@ command_t commands[] = { "\t\t(all replies to a particular message appear immediately\n" "\t\tafter that message in date order).\n" "\n" + "\t\tSupported options for show include:\n" + "\n" + "\t\t--only-matching-messages\n" + "\n" + "\t\t\tUsing this option will prevent output of any messages\n" + "\t\t\tthat do not match the search terms.\n" + "\n" "\t\tThe output format is plain-text, with all text-content\n" "\t\tMIME parts decoded.
