Create PHP array from letters

Question

I would like to create a PHP array from the Serbian alphabet.

Out of

а б в г д ђ е ж з и ј к л љ м н њ о п р с т ћ у ф х ц ч џ ш
a b c č ć d dž đ e f g h i j k l lj m n nj o p r s š t u v z ž

should become this (a custom array):

'а': 'a',
'б': 'b',
'в': 'c',
'г': 'č',
'д': 'ć',

How can I do this with awk or sed?

Answer 1

This gets pretty close:

$ awk 'NR==1 { for( i=1; i<=NF; i++ ) {out[i][0]=$i } } NR==2 { for( i=1; i<=NF; i++) {out[i][1]=$i }  } END {for( i=1; i<=NF; i++ ) { print "\""out[i][0]"\":\""out[i][1]"\","}}' input
"а":"a",
"б":"b",
"в":"c",
"г":"č",
"д":"ć",
"ђ":"d",
"е":"dž",
"ж":"đ",
"з":"e",
"и":"f",
"ј":"g",
"к":"h",
"л":"i",
"љ":"j",
"м":"k",
"н":"l",
"њ":"lj",
"о":"m",
"п":"n",
"р":"nj",
"с":"o",
"т":"p",
"ћ":"r",
"у":"s",
"ф":"š",
"х":"t",
"ц":"u",
"ч":"v",
"џ":"z",
"ш":"ž",

Answer 2

With zsh using its ${a:^b} array zipping operator:

{read -A a; read -A b} < your-file-with-those-2-lines.txt
printf "'%s': '%s',\n" ${a:^b}

Answer 3

In bash, with parallel arrays:

$ read -a src < <(sed -n 1p input)
$ read -a dest < <(sed -n 2p input)
$ for((i=0; i < "${#src[@]}"; i++))
do
  printf "'%s': '%s',\n" "${src[i]}" "${dest[i]}"
done

The output is:

'а': 'a',
'б': 'b',
'в': 'c',
'г': 'č',
'д': 'ć',
'ђ': 'd',
'е': 'dž',
'ж': 'đ',
'з': 'e',
'и': 'f',
'ј': 'g',
'к': 'h',
'л': 'i',
'љ': 'j',
'м': 'k',
'н': 'l',
'њ': 'lj',
'о': 'm',
'п': 'n',
'р': 'nj',
'с': 'o',
'т': 'p',
'ћ': 'r',
'у': 's',
'ф': 'š',
'х': 't',
'ц': 'u',
'ч': 'v',
'џ': 'z',
'ш': 'ž',

Using AWK:

awk '                                  
BEGIN { OFS="'"': '"'";start=1 }       
NR>=start && $0!="" {                  
    for(i=1;i<=NF;i++)                 
        a[i]=a[i] (NR==start?"":OFS) $i
    }
END {                                  
    for(j=1;j<i;j++)                   
        print "'"'"'"a[j]"'"',"'"                     
}' file.txt

Output

'а': 'a',
'б': 'b',
'в': 'c',
'г': 'č',
'д': 'ć',

Answer 5

printf  "'%s' : '%s',\n" $(datamash -W transpose < input.txt)

Input

а б в г д ђ е ж з и ј к л љ м н њ о п р с т ћ у ф х ц ч џ ш
a b c č ć d dž đ e f g h i j k l lj m n nj o p r s š t u v z ž

Output

'а' : 'a',
'б' : 'b',
'в' : 'c',
'г' : 'č',
'д' : 'ć',
'ђ' : 'd',
'е' : 'dž',
'ж' : 'đ',
'з' : 'e',
'и' : 'f',
'ј' : 'g',
'к' : 'h',
'л' : 'i',
'љ' : 'j',
'м' : 'k',
'н' : 'l',
'њ' : 'lj',
'о' : 'm',
'п' : 'n',
'р' : 'nj',
'с' : 'o',
'т' : 'p',
'ћ' : 'r',
'у' : 's',
'ф' : 'š',
'х' : 't',
'ц' : 'u',
'ч' : 'v',
'џ' : 'z',
'ш' : 'ž',

Answer 6

You ask for awk but you want to create PHP array, so I figured I'd give you a PHP way of doing it - and yes, you can run PHP from command line...

Stick your 2 lines into a file

а б в г д ђ е ж з и ј к л љ м н њ о п р с т ћ у ф х ц ч џ ш
a b c č ć d dž đ e f g h i j k l lj m n nj o p r s š t u v z ž

And then read that file with file() which brings each line into an element in an array.

Then loop through that array, breaking each line into its own array based on space separation using explode()

Then loop through your 2 lines and rebuild an associative array.

I do notice the last character in the first line seems to bring along a new line character, but that could be an encoding issue... not familiar enough with working with foreign character sets.

<?php

$letters=file("letters");

for($i=0;$i<count($letters);$i++){
    $line[$i]=explode(" ",$letters[$i]);
}

for($i=0;$i<count($line[1]);$i++){
        $newArray[$line[0][$i]]=$line[1][$i];
}

print_r($newArray);

?>

awk 'NR==1 { printf "%s\n",'$0' }' input.txt | tr ' ' '\n' > a.txt
awk 'NR== 2{ printf "%s\n",'$0' }' input.txt | tr ' ' '\n' >. b.txt
paste -d : a b
