Foremost is that it will dramatically simplify +the quoting for batch tagging, which shares the same input format. +While the hex-encoding is no better or worse for the simple ID queries +used by dump/restore, it becomes onerous for general-purpose queries +used in batch tagging. It also better handles strange cases like +"id:foo and bar", since this is no longer syntactically valid. +--- + notmuch-dump.c | 9 +++++---- + notmuch-restore.c | 22 ++++++++++------------ + tag-util.c | 6 ------ + test/dump-restore | 14 ++++++++------ + 4 files changed, 23 insertions(+), 28 deletions(-) + +diff --git a/notmuch-dump.c b/notmuch-dump.c +index 29d79da..bf01a39 100644 +--- a/notmuch-dump.c ++++ b/notmuch-dump.c +@@ -20,6 +20,7 @@ + + #include "notmuch-client.h" + #include "dump-restore-private.h" ++#include "string-util.h" + + int + notmuch_dump_command (unused (void *ctx), int argc, char *argv[]) +@@ -141,13 +142,13 @@ notmuch_dump_command (unused (void *ctx), int argc, char *argv[]) + fprintf (stderr, "Error: cannot dump message id containing line break: %s\n", message_id); + return 1; + } +- if (hex_encode (notmuch, message_id, +- &buffer, &buffer_size) != HEX_SUCCESS) { +- fprintf (stderr, "Error: failed to hex-encode msg-id %s\n", ++ if (make_boolean_term (notmuch, "id", message_id, ++ &buffer, &buffer_size)) { ++ fprintf (stderr, "Error: failed to quote message id %s\n", + message_id); + return 1; + } +- fprintf (output, " -- id:%s\n", buffer); ++ fprintf (output, " -- %s\n", buffer); + } + + notmuch_message_destroy (message); +diff --git a/notmuch-restore.c b/notmuch-restore.c +index 9ed9b51..77a4c27 100644 +--- a/notmuch-restore.c ++++ b/notmuch-restore.c +@@ -207,7 +207,7 @@ notmuch_restore_command (unused (void *ctx), int argc, char *argv[]) + INTERNAL_ERROR ("compile time constant regex failed."); + + do { +- char *query_string; ++ char *query_string, *prefix, *term; + + if (line_ctx != NULL) + talloc_free (line_ctx); +@@ -220,19 +220,17 @@ notmuch_restore_command (unused (void *ctx), int argc, char *argv[]) + &query_string, tag_ops); + + if (ret == 0) { +- if (strncmp ("id:", query_string, 3) != 0) { +- fprintf (stderr, "Warning: unsupported query: %s\n", query_string); ++ ret = parse_boolean_term (line_ctx, query_string, ++ &prefix, &term); ++ if (ret) { ++ fprintf (stderr, "Warning: cannot parse query: %s\n", ++ query_string); ++ continue; ++ } else if (strcmp ("id", prefix) != 0) { ++ fprintf (stderr, "Warning: not an id query: %s\n", query_string); + continue; + } +- /* delete id: from front of string; tag_message +- * expects a raw message-id. +- * +- * XXX: Note that query string id:foo and bar will be +- * interpreted as a message id "foo and bar".
