+FWIW, I actually have a hacky date parser baked into my\r
+remote-usage-and-other-stuff script (a more idiosyncratc python\r
+version of the bash script on the wiki). I found that I needed\r
+date-searching pretty frequently, since language and senders seem to be\r
+repeated pretty often in my world. It just parses a "date:" term, passes\r
+it to GNU date, and proceeds with a term in notmuch language. It also\r
+does some day-rounding, since by "date:'2 days ago'..yesterday", I mean\r
+"beginning of day before yesterday to end of yesterday," not "48 hours\r
+ago until 24 hours ago."\r
+\r
+I'm not swearing by its efficiency, or even its correctness, but it has\r
+made my life easier. The basics are as follows:\r
+\r
+ DATE_PATTERN = re.compile(r'^date:([^.]+)(\.\.)?([^.]+)?')\r
+ \r
+ def replace_date_args(st):\r
+ out = subprocess.check_output([GNU_DATE, "+%s", "-d", st])\r
+ return out.strip()\r
+ \r
+ def round_day_down(timestamp):\r
+ tup = datetime.fromtimestamp(int(timestamp)).date().timetuple()\r
+ return time.mktime(tup)\r
+ \r
+ def round_day_up(timestamp):\r
+ date = datetime.fromtimestamp(int(timestamp)).date()\r
+ date += timedelta(days=1)\r
+ tup = date.timetuple()\r
+ return time.mktime(tup)\r
+ \r
+ def parse_date_args(st):\r
+ re_match = DATE_PATTERN.match(st)\r
+ if re_match:\r
+ grps = re_match.groups()\r
+ start_term = grps[0]\r
+ if not (grps[1] or grps[2]):\r
+ stop_term = start_term\r
+ elif not grps[2]:\r
+ stop_term = "now"\r
+ else:\r
+ stop_term = grps[2]\r
+ \r
+ try:\r
+ start = round_day_down(replace_date_args(start_term))\r
+ stop = round_day_up(replace_date_args(stop_term))\r
+ return "%d..%d" % (start, stop)\r
+ except OSError:\r
+ return st\r
+ else:\r
+ return st\r
+\r
+And then in the main routine, I have a parse-and-replace step:\r
+\r
+ args = sys.argv[1:]\r
+ try:\r
+ if args[-1] == ")'":\r
+ args = args[:-2] + shlex.split(sys.argv[-2]) + [")'"]\r
+ else:\r
+ args = args[:-1] + shlex.split(sys.argv[-1])\r
+ except IndexError, ValueError:\r
+ pass\r
+\r
+ args = [parse_date_args(a) for a in args] \r
+\r
+I'm only giving the relevant parts here, of course.\r
+\r
+Best,\r
