2025-01-23all: replace [lib/bytes.WriteXxx] with standard libraryShulhan
The "encoding/binary.BigEndian" in standard library provides method PutXxx that do the same thing.
2025-01-23all: replace "lib/bytes.ReadXxx" with standard libraryShulhan
Package "encoding/binary" from standard library support reading integer from bytes using BigEndian, LittleEndian variables.
2025-01-23all: replace "lib/bytes.AppendXxx" with standard libraryShulhan
Since Go 1.19, package "encoding/binary.BigEndian" support appending byte order.
2025-01-22lib/bytes: replace Copy and Concat with standard libraryShulhan
Since Go 1.20, the standard bytes package have the Copy function. Since Go 1.22, the standard slices package have the Concat function.
2024-12-28lib/bytes: split the hexdump related functions to separate packageShulhan
Package hexdump implements reading and writing bytes from and into hexadecimal number. It support parsing output from hexdump(1) tool.
2024-09-30lib/bytes: add function AppendInt64 and AppendUint64Shulhan
The AppendInt64 append an int64 value into slice of byte. The AppendUint64 append an uint64 value into slice of byte.
2024-03-26lib/bytes: add parameter networkByteOrder to ParseHexDumpShulhan
If networkByteOrder is true, the ParseHexDump read each hex string in network byte order or as order defined in text. While at it, fix reading and parsing single byte hex.
2024-03-02all: move the repository to "git.sr.ht/~shulhan/pakakeh.go"Shulhan
There are several reasons that why we move from github.com. First, related to the name of package. We accidentally name the package with "share" a common word in English that does not reflect the content of repository. By moving to other repository, we can rename it to better and unique name, in this "pakakeh.go". Pakakeh is Minang word for tools, and ".go" suffix indicate that the repository related to Go programming language. Second, supporting open source. The new repository is hosted under sourcehut.org, the founder is known to support open source, and all their services are licensed under AGPL, unlike GitHub that are closed sources. Third, regarding GitHub CoPilot. The GitHub Terms of Service [1], allow any public content that are hosted there granted them to parse the content. On one side, GitHub helps and flourish the open source, but on another side have an issues regarding scraping the copyleft license [2].

2023-06-04lib/bytes: add function RemoveSpacesShulhan
Unlike TrimSpaces, which only remove spaces on beginning and end, RemoveSpaces remove all spaces including in between characters.
2023-04-13lib/bytes: change the package name in Example to have _test suffixShulhan
Package name in test Example should be different with the actual package. This is to minimize leaking un-exported functions or methods.
2023-04-05lib/bytes: implement function ParseHexDumpShulhan
The ParseHexDump parse the default output of [hexdump](1) utility from parameter in back into stream of byte. An example of default output of hexdump is 0000000 7865 5f70 6964 2f72 0000 0000 0000 0000 0000010 0000 0000 0000 0000 0000 0000 0000 0000 * 0000060 0000 0000 3030 3030 3537 0035 3030 3130 The first column is the address and the rest of the column is the data. Each data column is 16-bit words in big-endian order, so in the above example, the first byte would be 65, second byte is 78 and so on. The asterisk "*" means that the address from 0000020 to 0000050 is equal to the previous line, 0000010. [hexdump]: https://man.archlinux.org/man/hexdump.1
2023-04-05lib/bytes: add function TrimNullShulhan
The TrimNull function remove 0 value ("\0" or NULL in C) at leading and trailing of input.
2023-04-04lib/bytes: changes the DumpPrettyTable output formatShulhan
The change is to accommodate large bytes data, more than 0xFFFF. The hex address in the first column is increased to 8 digits, the characters compacted without space in between.
2023-03-22lib/bytes: add function DumpPrettyTableShulhan
The DumpPrettyTable write each byte in slice data as hexadecimal, ASCII character, and integer with 8 columns width.
2023-03-22lib/bytes: add function SplitEachShulhan
The SplitEach funciton split the slice of byte into n number of bytes. If n is less or equal than zero, it will return the data as chunks.
2021-10-17lib/bytes: refactoring and cleaning up the bytes packageShulhan
The bytes package, and many other packages in this module, is written when I still learning and using the Go language for master thesis. Some of the code, like function signature, does not follow the Go idiom, at least not how the Go source code looks like. A breaking changes, * WriteUint16 and WriteUint32 accept slice only without pointer. There is no need to pass slice as pointer to function if we want to modify the content, as long as the backing storage is not changed. Bug fixes, * PrintHex: fix print layout on the last line * ReadHexByte: fix possible index out of range * SkipAfterToken return -1 and false if no token found, as promised in the comment, instead of the length of text. We move all unit test to example so we have test and example in the documentation at the same time. This changes make all test coverage 100%.
2021-10-14lib/bytes: refactoring AppendXxx functionsShulhan
Previously, we pass pointer to slice on AppendInt16, AppendInt32, AppendUint16, and AppendUint32 functions. This model of function signature is not a Go idiom. It is written when I am still new to Go.
2019-09-27bytes: add function to get indexes of word in stringShulhan
Unlike Indexes, the word parameter must be separated by space or placed at beginning or end of string.
2019-09-25bytes: add function to take snippets from string by indexesShulhan
2019-09-24bytes: add function get all indexes of token in stringShulhan
