Use list-transduce. 2023-10-14T22:38:58+00:00 Arun Isaac 2023-10-14T22:38:58+00:00 urn:sha1:e200e606900328bea1c237287d55ccd1f2b3ff2f list-transduce allows us to see desired house listings as soon as they are found. We don't have to wait until all desired house listings are processed. * rent.scm (main): Use list-transduce. Abstract JSON requests. 2023-10-14T20:46:45+00:00 Arun Isaac 2023-10-14T20:46:45+00:00 urn:sha1:82333d70f3a5dc64af99463516c5490bfd4e3894 * rent.scm (json-get): New function.

(cycling-distances): New function. (%wembley-stadium): New variable. (list-house): Use cycling-distances with multiple destinations. Directly query TfL API to find tube lines at station. 2023-10-14T20:33:57+00:00 Arun Isaac 2023-10-14T20:08:29+00:00 urn:sha1:156dd142883f924cdce11e9ddd41dc11ed604294 Earlier, we were laboriously building a lookup table mapping all tube lines to the stations they serve, and inverting that lookup table. * rent.scm (all-tube-lines, stations-on-line): Delete functions. (lines-at-station): Rewrite to directly query TfL API. Show hours live in more human-readable units. 2023-10-13T18:55:41+00:00 Arun Isaac 2023-10-13T18:53:47+00:00 urn:sha1:5550bdf055b8ec9619f5ebfe6c47e13fb4605590 * rent.scm (list-house): Show hours live in hours or days as appropriate.

Add date constructor. 2023-09-26T09:34:10+00:00 Arun Isaac 2023-09-26T09:32:59+00:00 urn:sha1:392bca3614fdef2e2fc23baca3e86ba46b2a5b81 * rent.scm (date): New function.
