Overview
| Comment: | Extend functionality to sum up all wind directions by mapping. Need to tidy up formatting and make it consistent and sort out the naming of variables - it's such a mess. |

| 20:43 | Housekeeping: Formatting, variable naming consistency, etc - Get rid of the mixed up mess of CamelCase, underscores, prefixes, suffixes, abbreviations, full names, etc. - Make indenting of lists:map functions consistent - Remove spurious whitespace check-in: 301914a6a1 user: base@atomicules.co.uk tags: trunk, origin/master | |

| 17:52 | Yay! Working prototype. Will sum up the distances of headwinds... ...for a polyline route. I'd made silly mistakes like forgetting which order the list of tuples were in. I.e {Distances, Wind} or {Wind, Distances}. It doesn't really matter which order I use, but I should back sure it is consistent and matches the variable naming. Now need to extend this to sum up all wind directions and check for other bugs (such as sum of distances making sense, headwinds are actually headwinds and not tailwinds, etc). check-in: 289839a15d user: base@atomicules.co.uk tags: trunk, origin/master | |
