Golang : Spell checking with ispell example
Chinese New Year for 2017 celebration just over and now it is time to get back to work. Here is a simple example on how to wrap ispell
program in Golang. ispell
is a command line utility that can be used to check if a word is spelled correctly and if not, it will give a list of suggestions.
Pretty straightforward explanation can be found in the code below. This version should work correctly for International Ispell Version 3.4.00 8 Feb 2015
.
Here you go!
package main
import (
"fmt"
"os"
"os/exec"
"strings"
)
func handleError(err error) {
if err != nil {
fmt.Println(err)
os.Exit(1)
}
}
func ispellWrapper(inputWord string) string {
cmd := exec.Command("ispell")
stdin, err := cmd.StdinPipe()
handleError(err)
stdin.Write([]byte(inputWord + "\n"))
stdin.Close()
data, err := cmd.Output()
if err != nil {
panic(err)
}
// skip the credit line and get the remainder text
interestData := data[52:]
// check for "word: ok"
test := string(interestData[:8])
if (strings.Contains(test, "word: ok")) || (strings.Contains(test, "word: how")) {
//fmt.Println("Word ok")
return "Word ok"
} else {
// remove the "how about:" and the new line prompt "word: "
// and return the suggestions from ispell
test1 := interestData[17 : len(interestData)-7]
trimmed := strings.TrimSpace(string(test1))
return trimmed
}
}
func main() {
// spell check some words, if nothing is wrong with the given word
// you will get "Word ok" else you will get suggestions from ispell
fmt.Println(ispellWrapper("hello"))
fmt.Println(ispellWrapper("stinge"))
fmt.Println(ispellWrapper("wattee"))
}
Output:
Word ok
singe, sting, stinger, stings, stingy, tinge
wattle
Happy coding!
