If you are using NHTSA's VIN decoder to get information regarding the U.S. Electric Vehicle Tax Credit, please refer to information released by the U.S. Department of Energy, U.S. Department of the Treasury and Internal Revenue Service, and these FAQs.
This tool is designed to solve a wide variety of codes and ciphers (currently 255 supported variations). To use this tool, enter the encrypted text in the box below along with any other relevant data (keywords, alphabets, numbers, etc) and it will attempt to solve it for you. See the FAQ below for more details.
This multi decoder is designed to support a large number of codes and ciphers. Not all codes and ciphers have keywords, alphabets, numbers, letter translation, etc so if the code or cipher doesn't require it, those fields will be ignored. If one does require something, the text of that box will be updated to tell you what it is missing in order to decode.
Typically you would put any keywords in the first Key/Alphabet box and any custom alphabets in the next one. If all you have are keywords or alphabets, try rotating the order just in case the cipher was coded with them switched.
If you find any tools that aren't working quite right, please reach out to me. It would be helpful if you provided as much information as you can and an example of how it should be.
Studying the docs and implementations, my understanding is that Decoders are immutable value type objects. That means that it should be safe to make copies of them. I'd like to extract the Decoder instance so that I can make some more convenient top-level functions.
With that, I can create more powerful versions of Decodable that pass parameters (as with DecodingConfiguration). I currently have to create top-level wrapper objects to get the process started, just to get a Decoder.
Decoder is intentionally meant to be opaque to give implementations as much flexibility as possible to be performant, which means that you might not be holding on to the type of object you may think you are.
(While originally working on this, one ideal goal was to have the compiler prevent escaping references to Encoder/Decoder and their containers past the end of the method [which would much more strongly codify that this shouldn't be possible], but to this day I don't know how feasible that is; I'm not certain that even move-only types would be enough to express this restriction.)
While in some cases they might be, I don't think this is the norm. Many Decoders are neither immutable nor value types, since they can have reference semantics and mutable internal state. JSONDecoder's internal __JSONDecoder, for instance, is a class with exactly such state:
No, this is neither safe in the general case today, nor recommended. You should not hold on to an Encoder or its containers past the end of an encode(to:) call, nor a Decoder or its containers past the end of an init(from:) call; doing so can actually affect the results of encoding and decoding in unpredictable ways.
Thanks. I'd been studying JSONDecoderImpl instead of the Darwin version, I thought it was more indicative of the intended promises than it is. (But the lack of explicit promises is why I posted the question. :D)
Out of curiosity, what were the types of additions you were looking to make with an escaped Decoder? There might be other options that fit within the current promises that Codable does make. (e.g., it's sadly not strongly typed, but: usually threading additional data in can be done with userInfo, and there's even room for fairly flexible communication through that, depending on what you're looking for.)
This doesn't exist for any reason except to pull apart the response. It is completely possible to make this generic if there are several responses with the same structure, but if the structures are more adhoc, it's kind of annoying to make the extra layer.
I have other approaches that I'm exploring to improving ad-hoc decoding, but often a handy thing was to get my hands on a Decoder, and the only way I can do that is with a top-level type. That said, the wrapper type hasn't been my biggest problem. It was just something I was exploring how to remove.
Passing parameters is a very early exploration into tracking recovered errors, and providing configuration (for example, formatters). userInfo is very ugly to use. It has no type safety and there's no way to make values required. I don't have any clear question here; I'm still exploring. I just didn't want to get too far down the "escape a Decoder" road without checking its legitimacy.
BTW, this does point to another question I should ask. Is it safe to fetch more than one keyed container from the same Decoder. I'd assumed "sure, that's fine" but I suddenly realized it may not be fully safe.
I've explored several ways to encode and decode this, but I'm now questioning whether they're all legal. For example, this first creates a container keyed by CodingKeys, and then a separate one keyed by AnyCodingKey (subtracting out the explicit keys).
I believe I have my own answer from the docs. A keyed decoding container is documented to be "a view" over the decoder's storage. That seems pretty explicit that I'm free to create different views over the same storage.
Exactly. Containers are intended to be views into the data the decoder is holding at the current coding path, and conforming implementations should allow you to ask for any type of container you want, as many times as you want (and just be prepared to handle a type mismatch for keyed vs. unkeyed containers, if relevant).
What you are trying to solve is a common problem since Codable was introduced. My rule of thumb is to avoid to try to go against the design but play by the rules. Regarding Codable it is fairly acceptable to do so since property wrappers were introduced. In your case like with @Contained(in: "response", "result"). It can get noisy but it is solid. I know that I'm not going to get into troubles with this in the future. I use these a lot do deal with many problems that I'm otherwise unable to naturally solve on Coders. Like for instance to support different types of internet time formats etc. Actually I've needed so many of them (correctors, dealing with optionals, enums resilient to unknowns, ...) that I've found it better to have a general @Transcoded to keep all those "Codable add-ons" under a single namespace.
This isn't a direct answer to your question though. I don't have any. I just feel more safe to do these adjustments on Codables instead of Coders.
But note that BART is a seq2seq (encoder-decoder) model, it has been pre-trained in an encoder-decoder set-up, so the best results will probably be obtained by using both the encoder and decoder. But of course you can still use only the decoder if you want
I would like to program some led strips through a dmx controller but I am having a problem finding a profile that will control my lights with the ION console. The controller is one of these DC 12-24V 3 Channels DMX 512 Decoder - DMX Driver Controller for LED Lights and DMX Devices bought through Amazon. I have seen other people sue these decoders but they are not using an ION. Some help would be greatly appreciated. The lights are RGB with dimming capability.
I'm attempting to enable the quadrature decoder in a K10 series part. I have an encoder connected to inputs PHA/B or PTA10 & 11, corresponding to FTM2. Reading the manual, in order to enable this, I need to set FTMEN and QUADEN. Here's what I did:
I've read and reread the section of the manual on quadrature decoder mode, and I can't see anything in the block diagram or anywhere else that I'm not putting into the required state. I have also tried the same configuration with FTM1, and got the same results. What am I missing?
There is something important here, QUADEN field selects quadrature mode for FTM and has to be written before FTM configuration. Also FTM1_SC[CLKS] needs to be 0 during the configuration in order to apply changes, after that you need to select a Clock Source.
Thanks for the suggestions. I found that if I write something other than 0 to the CNTIN register I can count from whatever I write up to 0 before the counter stops counting, & counting works in both directions. If I look at the FTM2_MOD register in codewarrior, it's always 0, no matter what I write to it. Not only that, but the FTM_CNT register doesn't appear to be writable either. It comes up with a count (consistently) but it's not what I wrote, ever. Are these registers locked, or only writable at certain times? Is FTM2_MOD not readable? Do I need to write something somewhere else first in order to make it work?
The 'SDXH167_octalL_16.spj' (download) is the current factory-loaded sound project for the SDXH167 and will download and run on any 16Mbit "X" series Digitrax sound decoder. It will allow return to factory sound after you try one of the many other schemes available on Sound Depot, or other .spj sources." The 'sdxh167d_20may24.dmf' (download) file upgrades a SDXH167 decoder to XF capability for expanded function and sound mapping, and other maintenance updates. It will set CV253 to 6 after a CV8 to 8 reset. See the Series7 CV definitions document for CV settings, or use the DT602 with latest XF editor capability or JMRI to configure XF.
