Bash : Read each line of Localizable.strings

Question

In Xcode we have a Localizable.string file we used to support multiple languages in our app. I want to spell check the Localizable.string file. When I use this script the output gets printed to the console

cat ~/Desktop/Localizable.strings

But when I try to read line by line to spell check using this script a bunch of blank lines are printed to the console.

cat ~/Desktop/Localizable.strings | while read line; do
echo $line
done

This is how the Localizable.strings file looks like. It has a key and a value. I only want to check the Value

"SOME_KEY" = "Spell check this";

Any ideas?

Answer 1

This will print all values of a specified Localizable.strings file

plutil -p $FILE_PATH | grep '" *=> *"' | while read line; do key=$(echo "$line" | sed -E 's/(.*)=>(.*)/\2/') echo $key done

Here is the Swift 5 version of @user529758's answer:

import Foundation

// ref: https://stackoverflow.com/a/15426631
let path = CommandLine.arguments[1]
let url = URL(fileURLWithPath: path)
let dict = NSDictionary.init(contentsOf: url)

for value in dict?.allValues ?? [] {
    print(key)
}

run via swift main.swift /path/to/Localizable.strings
