 goquery brings a syntax and a set of features similar to [jQuery][] to the [Go language][go]. It is based on Go's [net/html package][html] and the CSS Selector library [cascadia][]. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), detach()) have been left off.

Invalid selector strings compile to a `Matcher` that fails to match any node. Behaviour of the various functions that take a selector string as argument follows from that fact, e.g. (where `~` is an invalid selector string):

+# Unicode Text Segmentation for Go
+
+[![Godoc Reference](https://img.shields.io/badge/godoc-reference-blue.svg)](https://godoc.org/github.com/rivo/uniseg)
+[![Go Report](https://img.shields.io/badge/go%20report-A%2B-brightgreen.svg)](https://goreportcard.com/report/github.com/rivo/uniseg)
+
+This Go package implements Unicode Text Segmentation according to [Unicode Standard Annex #29](http://unicode.org/reports/tr29/) (Unicode version 12.0.0).
+
+At this point, only the determination of grapheme cluster boundaries is implemented.
+
+## Background
+
+In Go, [strings are read-only slices of bytes](https://blog.golang.org/strings). They can be turned into Unicode code points using the `for` loop or by casting: `[]rune(str)`. However, multiple code points may be combined into one user-perceived character or what the Unicode specification calls "grapheme cluster". Here are some examples:
+
+|String|Bytes (UTF-8)|Code points (runes)|Grapheme clusters|
+|-|-|-|-|
+|Käse|6 bytes: `4b 61 cc 88 73 65`|5 code points: `4b 61 308 73 65`|4 clusters: `[4b],[61 308],[73],[65]`|
+|🏳️‍🌈|14 bytes: `f0 9f 8f b3 ef b8 8f e2 80 8d f0 9f 8c 88`|4 code points: `1f3f3 fe0f 200d 1f308`|1 cluster: `[1f3f3 fe0f 200d 1f308]`|
+|🇩🇪|8 bytes: `f0 9f 87 a9 f0 9f 87 aa`|2 code points: `1f1e9 1f1ea`|1 cluster: `[1f1e9 1f1ea]`|
+
+This package provides a tool to iterate over these grapheme clusters. This may be used to determine the number of user-perceived characters, to split strings in their intended places, or to extract individual characters which form a unit.
+
+## Installation
+
+```bash
+go get github.com/rivo/uniseg
+```
+
+## Basic Example
+
+```go
+package uniseg
+
+import (
+	"fmt"
+
+	"github.com/rivo/uniseg"
+)
+
+func main() {
+	gr := uniseg.NewGraphemes("👍🏼!")
+	for gr.Next() {
+		fmt.Printf("%x ", gr.Runes())
+	}
+	// Output: [1f44d 1f3fc] [21]
+}
+```
+
+## Documentation
+
+Refer to https://godoc.org/github.com/rivo/uniseg for the package's documentation.
+
+## Dependencies
+
+This package does not depend on any packages outside the standard library.
+
+## Your Feedback
+
+Add your issue here on GitHub. Feel free to get in touch if you have any questions.
+
+## Version
+
+Version tags will be introduced once Golang modules are official. Consider this version 0.1.
