// Package tabwriter implements a write filter (tabwriter.Writer) that
// translates tabbed columns in input into properly aligned text.
//
// The package is using the Elastic Tabstops algorithm described at
// http://nickgravgaard.com/elastictabstops/index.html.
//
// The text/tabwriter package is frozen and is not accepting new features.
// based on https://github.com/golang/go/blob/master/src/text/tabwriter/tabwriter.go Last modified 690ac40 on 31 Jan

// ----------------------------------------------------------------------------
// Filter implementation
// A cell represents a segment of text terminated by tabs or line breaks.
// The text itself is stored in a separate buffer; cell only describes the
// segment's size in bytes, its width in runes, and whether it's an htab
// ('\t') terminated cell.
type cell struct {
size int // cell size in bytes
width int // cell width in runes
htab bool // true if the cell is terminated by an htab ('\t')
}
// A Writer is a filter that inserts padding around tab-delimited
// columns in its input to align them in the output.
//
// The Writer treats incoming bytes as UTF-8-encoded text consisting
// of cells terminated by horizontal ('\t') or vertical ('\v') tabs,
// and newline ('\n') or formfeed ('\f') characters; both newline and
// formfeed act as line breaks.
//
// Tab-terminated cells in contiguous lines constitute a column. The
// Writer inserts padding as needed to make all cells in a column have
// the same width, effectively aligning the columns. It assumes that
// all characters have the same width, except for tabs for which a
// tabwidth must be specified. Column cells must be tab-terminated, not
// tab-separated: non-tab terminated trailing text at the end of a line
// forms a cell but that cell is not part of an aligned column.
// For instance, in this example (where | stands for a horizontal tab):
//
// aaaa|bbb|d
// aa |b |dd
// a |
// aa |cccc|eee
//
// the b and c are in distinct columns (the b column is not contiguous
// all the way). The d and e are not in a column at all (there's no
// terminating tab, nor would the column be contiguous).
//
// The Writer assumes that all Unicode code points have the same width;
// this may not be true in some fonts or if the string contains combining
// characters.
//
// If DiscardEmptyColumns is set, empty columns that are terminated
// entirely by vertical (or "soft") tabs are discarded. Columns
// terminated by horizontal (or "hard") tabs are not affected by
// this flag.
//
// If a Writer is configured to filter HTML, HTML tags and entities
// are passed through. The widths of tags and entities are
// assumed to be zero (tags) and one (entities) for formatting purposes.
//
// A segment of text may be escaped by bracketing it with Escape
// characters. The tabwriter passes escaped text segments through
// unchanged. In particular, it does not interpret any tabs or line
// breaks within the segment. If the StripEscape flag is set, the
// Escape characters are stripped from the output; otherwise they
// are passed through as well. For the purpose of formatting, the
// width of the escaped text is always computed excluding the Escape
// characters.
//
// The formfeed character acts like a newline but it also terminates
// all columns in the current line (effectively calling Flush). Tab-
// terminated cells in the next line start new columns. Unless found
// inside an HTML tag or inside an escaped text segment, formfeed
// characters appear as newlines in the output.
//
// The Writer must buffer input internally, because proper spacing
// of one line may depend on the cells in future lines. Clients must
// call Flush when done calling Write.

# 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.
