From: David Bremner <brem...@debian.org> sup is the old format, and remains the default, at least until restore is converted to parse this format.
Each line of the batch-tag format is modelled on the syntax of notmuch tag: - "notmuch tag" is omitted from the front of the line - The dump format only uses query strings of a single message-id. - Each space seperated tag/message-id is 'hex-encoded' to remove trouble-making characters. - It is permitted (and will be useful) for there to be no tags before the query. In particular this format won't have the same problem with e.g. spaces in message-ids or tags; they will be round-trip-able. --- dump-restore-private.h | 13 +++++++++++++ notmuch-dump.c | 48 ++++++++++++++++++++++++++++++++++++++++++------ 2 files changed, 55 insertions(+), 6 deletions(-) create mode 100644 dump-restore-private.h diff --git a/dump-restore-private.h b/dump-restore-private.h new file mode 100644 index 0000000..896a004 --- /dev/null +++ b/dump-restore-private.h @@ -0,0 +1,13 @@ +#ifndef DUMP_RESTORE_PRIVATE_H +#define DUMP_RESTORE_PRIVATE_H + +#include "hex-escape.h" +#include "command-line-arguments.h" + +typedef enum dump_formats { + DUMP_FORMAT_AUTO, + DUMP_FORMAT_BATCH_TAG, + DUMP_FORMAT_SUP +} dump_format_t; + +#endif diff --git a/notmuch-dump.c b/notmuch-dump.c index 88f598a..d2dad40 100644 --- a/notmuch-dump.c +++ b/notmuch-dump.c @@ -19,6 +19,7 @@ */ #include "notmuch-client.h" +#include "dump-restore-private.h" int notmuch_dump_command (unused (void *ctx), int argc, char *argv[]) @@ -43,7 +44,13 @@ notmuch_dump_command (unused (void *ctx), int argc, char *argv[]) char *output_file_name = NULL; int opt_index; + int output_format = DUMP_FORMAT_SUP; + notmuch_opt_desc_t options[] = { + { NOTMUCH_OPT_KEYWORD, &output_format, "format", 'f', + (notmuch_keyword_t []){ { "sup", DUMP_FORMAT_SUP }, + { "batch-tag", DUMP_FORMAT_BATCH_TAG }, + { 0, 0 } } }, { NOTMUCH_OPT_STRING, &output_file_name, "output", 'o', 0 }, { 0, 0, 0, 0, 0 } }; @@ -83,27 +90,56 @@ notmuch_dump_command (unused (void *ctx), int argc, char *argv[]) */ notmuch_query_set_sort (query, NOTMUCH_SORT_UNSORTED); + char *buffer = NULL; + size_t buffer_size = 0; + for (messages = notmuch_query_search_messages (query); notmuch_messages_valid (messages); notmuch_messages_move_to_next (messages)) { int first = 1; + const char *message_id; + message = notmuch_messages_get (messages); + message_id = notmuch_message_get_message_id (message); - fprintf (output, - "%s (", notmuch_message_get_message_id (message)); + if (output_format == DUMP_FORMAT_SUP) { + fprintf (output, "%s (", message_id); + } for (tags = notmuch_message_get_tags (message); notmuch_tags_valid (tags); notmuch_tags_move_to_next (tags)) { - if (! first) - fprintf (output, " "); + const char *tag_str = notmuch_tags_get (tags); - fprintf (output, "%s", notmuch_tags_get (tags)); + if (! first) + fputs (" ", output); first = 0; + + if (output_format == DUMP_FORMAT_SUP) { + fputs (tag_str, output); + } else { + if (hex_encode (notmuch, tag_str, + &buffer, &buffer_size) != HEX_SUCCESS) { + fprintf (stderr, "Error: failed to hex-encode tag %s\n", + tag_str); + return 1; + } + fprintf (output, "+%s", buffer); + } } - fprintf (output, ")\n"); + if (output_format == DUMP_FORMAT_SUP) { + fputs (")\n", output); + } else { + if (hex_encode (notmuch, message_id, + &buffer, &buffer_size) != HEX_SUCCESS) { + fprintf (stderr, "Error: failed to hex-encode msg-id %s\n", + message_id); + return 1; + } + fprintf (output, " -- id:%s\n", buffer); + } notmuch_message_destroy (message); } -- 1.7.10.4 _______________________________________________ notmuch mailing list notmuch@notmuchmail.org http://notmuchmail.org/mailman/listinfo/notmuch
