2024-03-05all: comply with linter recommendations #3Shulhan
For HTTP server that use TLS, set the minimum TLS version and ReadHeaderTimeout to mitigate slowloris attack. For HTTP client or server that parameterize the use of InsecureSkipVerify, annotate the line with "nolint:gosec" to allow the code pass the check. Library that still use sha1, in example in DKIM and TOTP, skip the warnings by annotating the line with "nolint:gosec". A pointer variable now allocated their address before assigning its value. Any error that returned now wrapped using "%w". Also, replace error checking using [errors.Is] or [errors.As] instead of using equal or not-equal operators. In "lib/http", replace any usage of "math/rand" with "crypto/rand". Any call of [math/big.Rat.SetString] now annotated with "nolint:gosec" since its false positive, the issue has been fixed in Go >= 1.17.7. Any switch case that does not cover the rest of the possible values now handled by adding the cases or by replacing the "default" case with the rest of values.
2024-03-05all: comply with linter recommendations #2Shulhan
HTTP request now implicitly create request with context. Any false positive related to not closing HTTP response body has been annotated with "nolint:bodyclose". In the example code, use consistent "// Output:" comment format, by prefixing with single space. Any comment on code now also prefixing with single space. An error returned without variables now use [errors.New] instead of [fmt.Errorf]. Any error returned using [fmt.Errorf] now wrapped using "%w" instead of "%s". Also, replace error checking using [errors.Is] or [errors.As], instead of using equal/not-equal operator. Any statement like "x = x OP y" now replaced with "x OP= y". Also, swap statement is simplified using "x, y = y, x". Any switch statement with single case now replaced with if-condition. Any call to defer on function or program that call [os.Exit], now replaced by calling the deferred function directly. Any if-else condition now replaced with switch statement, if possible.
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].

2023-12-13all: fix linter warnings reported by reviveShulhan
There are some reports that I disagree with revive, in example, code should not declare the type after variables. In my opinion, on some cases, declaring the type make the code more readable and explicit. Since I did not want to add new configuration file, we changes it and follow revive for now.
