text

A golang module for handling various text-related functions. Currently contains only a text wrapping function set.

Synopsis

This module provides a parser that consumes a string, treating it as UTF-8. It divides the string into "whitespace" and "words". Words are contiguous sequences of non-whitespace runes. The parser rearranges the string text into rows that are no longer than a specified length wide. It tries to break around whitespace. If a resulting row is a single word that exceeds the maximum line length, it breaks the word at exactly the line length, placing the remainder on the subsequent row (or rows, if the string is long enough).

Install

go get -u github.com/blorticus-go/text

Example

import "github.com/blorticus-go/text"
import "fmt"

func panicIfError(e error) {
    if e != nil {
        panic(e.Error())
    }
}

func main() {
    fh, err := os.Open(os.Args[1])
    panicIfError(err)

    wrapper := textwrapper.NewTextWrapper().
        UsingRowWidth(50).
        UsingIndentStringForRowsAfterTheFirst("   ")

    formattedString, err := wrapper.WrapUTF8TextFromAReader(fh)
    panicIfError(err)

    fmt.Print(formattedString)
}
