After go1.16, go will use module mode by default, even when the repository is checked out under GOPATH or in a one-off directory. Add go.mod, go.sum to keep this repo buildable without opting out of the module mode. > go mod init github.com/mmcgrana/gobyexample > go mod tidy > go mod vendor In module mode, the 'vendor' directory is special and its contents will be actively maintained by the go command. pygments aren't the dependency the go will know about, so it will delete the contents from vendor directory. Move it to `third_party` directory now. And, vendor the blackfriday package. Note: the tutorial contents are not affected by the change in go1.16 because all the examples in this tutorial ask users to run the go command with the explicit list of files to be compiled (e.g. `go run hello-world.go` or `go build command-line-arguments.go`). When the source list is provided, the go command does not have to compute the build list and whether it's running in GOPATH mode or module mode becomes irrelevant.

// Sanitized Anchor Names
|
|
//
|
|
// Blackfriday includes an algorithm for creating sanitized anchor names
|
|
// corresponding to a given input text. This algorithm is used to create
|
|
// anchors for headings when EXTENSION_AUTO_HEADER_IDS is enabled. The
|
|
// algorithm is specified below, so that other packages can create
|
|
// compatible anchor names and links to those anchors.
|
|
//
|
|
// The algorithm iterates over the input text, interpreted as UTF-8,
|
|
// one Unicode code point (rune) at a time. All runes that are letters (category L)
|
|
// or numbers (category N) are considered valid characters. They are mapped to
|
|
// lower case, and included in the output. All other runes are considered
|
|
// invalid characters. Invalid characters that preceed the first valid character,
|
|
// as well as invalid character that follow the last valid character
|
|
// are dropped completely. All other sequences of invalid characters
|
|
// between two valid characters are replaced with a single dash character '-'.
|
|
//
|
|
// SanitizedAnchorName exposes this functionality, and can be used to
|
|
// create compatible links to the anchor names generated by blackfriday.
|
|
// This algorithm is also implemented in a small standalone package at
|
|
// github.com/shurcooL/sanitized_anchor_name. It can be useful for clients
|
|
// that want a small package and don't need full functionality of blackfriday.
