海外TECH	DEV Community	Read All Files of Directory and Subdirectories with Recursive Generators in JavaScript	https://dev.to/zirkelc/read-all-files-of-directory-and-subdirectories-with-recursive-generators-in-javascript-2pbd	Read All Files of Directory and Subdirectories with Recursive Generators in JavaScriptReading all files from a directory and its subdirectories is a common requirement in many projects While there are several ways to accomplish this one approach is to use a recursive generator function to create a sequence of file paths Let s start by taking a look at the code import fs from fs import path from path export function readAllFiles dir string Generator lt string gt const files fs readdirSync dir withFileTypes true for const file of files if file isDirectory yield readAllFiles path join dir file name else yield path join dir file name The function readAllFiles takes a directory path as input and returns a generator object that creates a sequence of file paths Inside the function we first use fs readdirSync to read all files and directories in the specified directory We pass the withFileTypes option to get fs Dirent objects instead of filenames Then we loop through each file or directory with a for of loop If the current item is a directory we recursively call the readAllFiles function with the new directory path using the yield syntax This creates a nested sequence of file paths for each subdirectory If the current item is a file we use the path join function to construct the full path of the file and yield it Now that we have our generator function let s see how we can use it to read all the files in a directory and its subdirectories for const file of readAllFiles path to directory console log file We can simply use a for of loop to iterate through the generator object and print each file path to the console Using a recursive generator function to read all the files in a directory and its subdirectories has several benefits over other approaches Instead of pushing all file paths into an array the generator yields each path one at a time This means that only one file path is kept in memory at a time making it more memory efficient Moreover the generator only generates file paths when they are requested by the consuming code This means that if we only need to process a subset of the files we don t waste time and resources generating paths for files we don t need	2023-02-23 12:29:14

海外TECH	DEV Community	Bits and Bytes: A Comprehensive Guide to Bit Manipulation for Developers	https://dev.to/dariocasciato/bits-and-bytes-a-comprehensive-guide-to-bit-manipulation-for-developers-m5c	Bits and Bytes A Comprehensive Guide to Bit Manipulation for DevelopersAh bit manipulation Another classic when learning to develop embedded software It saved me half of my lifetime once when I found out that I could concatenate values that are saved in an array This was the piece of code unsigned long UID UID tempUID lt lt tempUID lt lt tempUID lt lt tempUID This is an example of bit manipulation The tempUID array holds one byte in every index To concatenate them you can use bit manipulation like this one It looks complicated at first I know But after this article you will exactly know how this works and feel like this this was my case What is Bit Manipulation Bit manipulation is the process of using bitwise operators to manipulate individual bits within a number or value It is very powerful when you have to make very specific operations It s not to be confused with logical operations which work on boolean values e g true false So let s get straight into it OperatorsThere are six different operators of which the last two are very similar to do bit manipulation These are the operators AND Operator amp The bitwise AND operator as it is in the name sets the bit to if the compared bits are both Input AInput BOutputThis operator is used for bit masking With bit masking you select specific bits to be read Here is an example result address amp xF xF gt bWith this mask xF the first four bits from the right do not have the possibility of becoming because with the AND operator both bits must be to obtain a So if address for example is the result would be OR Operator The bitwise OR operator sets the bit to if at least one bit is Input AInput BOutputThis operator is used a lot for combining values or concatenating them for concatenation you would also need bit shifting test x x gt test test x same resultThis will set the th bit of the variable test to regardless of the value of test XOR Operator The bitwise XOR operator is a very interesting one In my previous article I mentioned that this operator can be very powerful The XOR operator sets a bit to if the two compared bits are unequal Input AInput BOutputThere are many different use cases for the XOR operator such as encryption with a key toggling or change detection But there are many more I used the change detection for Edge detection In this example we are going to toggle values value value xFF xFF gt Every bit in value that is a will turn to since XOR will result in Every bit in value that is a will turn to since XOR will result in NOT Operator The bitwise NOT operator is the easiest one to understand It does exactly the same as in the example above for the XOR It inverts every bit The syntax is very simple InputOutputThis operator is very useful for example if you need to initialize a value inverted you can use the bitwise NOT operator value xF xF gt value value After the operation value is LEFTSHIFT Operator lt lt Now the interesting ones begin These operators do exactly the thing they are called They shift You only need to specify how many bits the value should be shifted As mentioned in the first example this is very useful to concatenate values value xF lt lt xF gt You have inputs with this operator The one on the left is the value that needs to be shifted and the right one specifies how many bits it needs to be shifted So the result of this example would be You can also see that the new bits that are pushed in from the right are This is default and cannot be changed RIGHTSHIFT Operator gt gt The right shift bitwise operator also shifts bits The only difference is that it shifts bits to the right Also this one can be used for concatenating values It also comes in handy in encryption You can shift a value in a direction by a known amount of times Combining it with other operators makes this extremely powerful value x gt gt x gt I think you can already guess the result If we shift x to the right by we get Understanding the first exampleNow that the theoretical part is done we should be able to understand the first example of bit manipulation I made The goal is to concatenate them all together to get one value that contains all other values unsigned long UID UID tempUID lt lt tempUID lt lt tempUID lt lt tempUID To illustrate this we assign a value to each array index HEX BINtempUID xA xA tempUID xFF xFF tempUID x x tempUID xF xF This bit manipulation involves two steps The first step is to shift the values and the second step is to combine them using the OR operator We need to shift all the values by the number given in the calculation tempUID shifted by tempUID shifted by tempUID shifted by tempUID not shiftedThe second step is to combine them using the OR operator UID So That s it When you first look at a calculation involving bit manipulation it can be confusing However when you split up the whole process into steps it becomes more comprehensible FinaleThank you for reading I hope you learned something new from this article The series will continue soon with a new article about structuring your firmware Feel free to leave any comments or questions below and I ll do my best to help you out May your code be bug free	2023-02-23 12:20:25
