It'd be great if we can have formatBytes32String and parseBytes32String in the utils. I guess there just is a mismatch in my use-case and what simdjson provides, I'll advise the company I work for to use RapidJSON instead. You should not need any Web3 libraries. So called strings are just char arrays. The null terminated strings are basically a sequence of characters, and the last element is one null character (denoted by '\0'). It may be a bug in web3, but I'm not certain. And neither tool highlights the core issue - passing a string that doesn't fit into a bytes32 should throw. (Basically Dog-people). Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Where bytes32 should be a bytes representation of the CDPId. I'm curious, what are you sending as the length to simdjson? What I have tried: I also had to install web3-utils separate from web3 and downgrade web3 to avoid errors. This is why the ethers.utils.stringToBytes32 and ethers.utils.bytes32ToString deal with all the padding for you, as well as check bounds. I will give it a try. Also, strings in JavaScript are already UTF-8 strings, so you do not need the toUtf8String. Such an ingenious transformation, beautiful! // pads 00s from left until the hex string is bytes32 const padded = ethers.utils.hexZeroPad (shortHexString, 32) Thanks @ricmoo! Would Marx consider salary workers to be members of the proleteriat? A single null byte is not sufficient for this code, because many Unicode characters contain null bytes as either the high or the low byte. Passing in the wrong length is actually ambiguous. If some code considers that the string content is . Tested using a function: createCharacter(bytes32 name, uint stat1, uint stat2). Well occasionally send you account related emails. rev2023.1.18.43173. There are dozens of other ways to store strings, but using a library is often better than making your own. (Basically Dog-people). Just for the sake of completeness and nail this down completely. And a few for which I think they just ignore anything after the closing bracket: ultrajson, json-parser. Or have a variant that did, or take in a second parameter on what bytesXX to align to? at CoderFixedBytes.encode (/node_modules/ethers/utils/abi-coder.js:473:20) The web3StringToBytes32 is more a string-to-hex than bytes32 conversion as it returns an arbitrary length hex string. :). I try in general to make sure if a developer is doing something they (in many cases) shouldn't, that they realize it. Have a question about this project? If the '\0' is at the end of the strings, why don't you trim it off before sending the content to the parser? So, I have confirmed with the author of Solidity that this is at least strange behaviour and likely a bug in web3. Maybe I'm going at this all the wrong way. Why does secondary surveillance radar use a different antenna design than primary radar? To learn more, see our tips on writing great answers.

Find centralized, trusted content and collaborate around the technologies you use most. Standard (18.1). It is literally one line of code to remove a zero padder. For Truffle, the answer is (2) - it does not truncate, but instead corrupts the data by appending the whole string as a series of bytes32, pushing the extra calldata out. This will encourage your compiler to barf if you ever accidentally try to pass it to a function expecting a C-style string. My greater project is to have a user input a string on the front-end that can be hashed with keccak256 then keyed to a value in a mapping in my contract.
, or , is an implementation-defined C++ null pointer constant in this International Due to a legacy Web3 bug, this currently sometimes works, but as you pointed out can corrupt things. How to convert a std::string to const char* or char*, Improve INSERT-per-second performance of SQLite. The string you sent is the full bytes sent to the network, including the function selector.

As soon as the parser doesn't see a \0, everything is fine. For lower case output, just change 7 to 39 in the code. The biggest problem with this convention is that there is many cases where it's inefficient. arguments: [stringArray.map(name => web3.utils.asciiToHex(name))] I'm need to make a "migrating from web3 to ethers.js" document sometime, and I will certainly add this.
