5/21/2023 0 Comments Morse decoder in forth![]() ![]() I couldn't find anything on the web that did this, not even close. I thought the best way to do this would be a visual decoder, where you can just position the "flags" the way you want it to. The best alternative I've seen is the "pie-slice" semaphore chart, but even that one takes feels slow and painful for me to read (even though in theory it should be just like the pigpen chart). You don't really have a search strategy besides looking through every single letter. Quick, what does the semaphore with left flag horizontal and right flag at a 45 degree angle towards the ground mean? Hunting for the right shape in the lookup table is tedious. In semaphore, there isn't a clear way to do this: no text representation, no hierarchy, no ordering. Similarly, if you wanted to decode Morse code by hand, you can use a Morse decoding tree to quickly converge on the right letter. Why? It has a visual hierarchy: even though there are four different subcharts in the lookup table, it is immediately obvious which one to look at from the shape of the code and the dot (or absence of a dot). It's not just that the encoding is visual.įor example, the pigpen cipher is very visual, but it's comparatively painless to decode. There are two distinct lines radiating out from a single point.īut even if I know that, it's still pretty tedious to actually decode it.įor encodings that are easily representable by text, there's often very good online tools to solve them -įor example, dCode has nice decoders for things likeīut none of the existing tools I found are very good for solving visual encodings like semaphore. ![]() It's usually fairly quick to recognize a code that could be semaphore: These are often encoded as times on a clock,īut sometimes also as things like tree branches or I've been doing a lot of puzzles lately with my friend Johnny, and these puzzles often involve flag semaphore, a visual representation of letters using the position of two flags. I can't believe you made my pipe dream into a reality, and it only took you about two days - Johnnyįor the record, it was much closer to 1.5 days for the code, but then I spent at least another half-day writing this post, so I guess he's not wrong. I recently built a point-and-click visual semaphore decoder for puzzling (link).Īs far as I can tell, it is the only semaphore decoder online that lets you enter inputs visually (but let me know if there are others!).
