Golang : Converting individual Jawi alphabet to Rumi(Romanized) alphabet example

Recently I've been busy enhancing my Jawi to Rumi converter and I found out that some Jawi words cannot be converted back to Rumi(Romanized) form if there's no available match in the map based dictionary. To tackle this type of problem, I've to devise a better way to convert the Jawi words to Rumi. One such way is to break the Jawi word into each individual characters and perform a map(a.k.a hash-table) search for the individual character.

Depending on the Jawi input, some Rumi results are easy to figure out. Words such as foto or syampu are easily comprehensible from their final Rumi result. However, some words will require the reader to have some ability to read Jawi. At the minimum, the reader needs to know about the placement rules of ا - alif alphabet in a word.

Ok, here you go!

 package main

 import (
  "log"
 )

 var jawiAlphabet = map[string]string{}
 var rumiAlphabet = map[string]string{}

 func main() {
  // build the Jawi map
  jawiAlphabet["ا"] = "alif"
  jawiAlphabet["ب"] = "ba"
  jawiAlphabet["ت"] = "ta"
  jawiAlphabet["ث"] = "sa(tha)"
  jawiAlphabet["ج"] = "jim"
  jawiAlphabet["چ"] = "ca"
  jawiAlphabet["ح"] = "ha(ḥa)"
  jawiAlphabet["خ"] = "kha(khO)"
  jawiAlphabet["د"] = "dal"
  jawiAlphabet["ذ"] = "zal(dhal)"

  jawiAlphabet["ر"] = "ra(rO)"
  jawiAlphabet["ز"] = "zai"
  jawiAlphabet["س"] = "sin"
  jawiAlphabet["ش"] = "syin"
  jawiAlphabet["ص"] = "sad(ṣod)"
  jawiAlphabet["ض"] = "dad(ḍod)"
  jawiAlphabet["ط"] = "ta(ṭo)"
  jawiAlphabet["ظ"] = "za(ẓo)"
  jawiAlphabet["ع"] = "ain"
  jawiAlphabet["غ"] = "ghain"

  jawiAlphabet["ڠ"] = "nga"
  jawiAlphabet["ف"] = "fa"
  jawiAlphabet["ڤ"] = "pa"
  jawiAlphabet["ق"] = "qaf"
  jawiAlphabet["ک"] = "kaf"
  jawiAlphabet["ݢ"] = "ga"
  jawiAlphabet["ل"] = "lam"
  jawiAlphabet["م"] = "mim"
  jawiAlphabet["ن"] = "nun"
  jawiAlphabet["و"] = "wau"

  jawiAlphabet["ۏ"] = "va"
  jawiAlphabet["ه"] = "ha"
  jawiAlphabet["ء"] = "hamzah"
  jawiAlphabet["ي"] = "ya"
  jawiAlphabet["ڽ"] = "nya"
  jawiAlphabet["ى"] = "e(ye)"

  // build the Rumi map
  rumiAlphabet["ا"] = "a"
  rumiAlphabet["ب"] = "b"
  rumiAlphabet["ت"] = "t"
  rumiAlphabet["ث"] = "t'"
  rumiAlphabet["ج"] = "j"
  rumiAlphabet["چ"] = "c"
  rumiAlphabet["ح"] = "H"
  rumiAlphabet["خ"] = "H'"
  rumiAlphabet["د"] = "d"
  rumiAlphabet["ذ"] = "d'"

  rumiAlphabet["ر"] = "r"
  rumiAlphabet["ز"] = "z"
  rumiAlphabet["س"] = "s"
  rumiAlphabet["ش"] = "s'"
  rumiAlphabet["ص"] = "S"
  rumiAlphabet["ض"] = "D"
  rumiAlphabet["ط"] = "T"
  rumiAlphabet["ظ"] = "Z"
  rumiAlphabet["ع"] = "g"
  rumiAlphabet["غ"] = "g'"

  rumiAlphabet["ڠ"] = "N"
  rumiAlphabet["ف"] = "f"
  rumiAlphabet["ڤ"] = "p"
  rumiAlphabet["ق"] = "q"
  rumiAlphabet["ک"] = "k"
  rumiAlphabet["ݢ"] = "k'"
  rumiAlphabet["ل"] = "l"
  rumiAlphabet["م"] = "m"
  rumiAlphabet["ن"] = "n"
  rumiAlphabet["و"] = "o"

  rumiAlphabet["ۏ"] = "v"
  rumiAlphabet["ه"] = "h"
  rumiAlphabet["ء"] = "-"
  rumiAlphabet["ي"] = "y"
  rumiAlphabet["ڽ"] = "ñ"
  rumiAlphabet["ى"] = "e"

  testRumi := "cendawan"
  testJawi := "چنداون"
  
  //testRumi := "foto"
  //testJawi := "فوتو"
  
  //testRumi := "syampu"
  //testJawi := "شمڤو"
  

  log.Println("Breaking down :", testRumi + " --> " + testJawi)

  var hurufResult []string
  var rumiResult []string
  


  for _,t := range testJawi {
 j := jawiAlphabet[string(t)]
 r := rumiAlphabet[string(t)]

 log.Println(string(t),j,r)
 hurufResult = append(hurufResult,j)
 rumiResult = append(rumiResult,r)
 

  }

  log.Println("hurufResult : ", hurufResult)
  log.Println("rumiResult : ", rumiResult)

 }

Sample output:

 2020/01/12 20:27:34 Breaking down : syampu --> شمڤو
 2020/01/12 20:27:34 ش syin s'
 2020/01/12 20:27:34 م mim m

 2020/01/12 20:27:34 hurufResult :  [syin mim pa wau]
 2020/01/12 20:27:34 rumiResult :  [s' m p o]

Hope this helps and happy coding!
