Automatically replace NSLocalizedString(...) in Swift with corresponding tr(...) calls for https://github.com/AliSoftware/SwiftGen. Copy both into the project and call 'sh replaceNSlocalized.sh'

replaceNSlocalized.sh

#/bin/sh

# Run this inside the project to replace NSLocalizedString calls with swiftgen calls in all .swift files.
# Do not forget to make a backup before.

find . -type f | grep ".swift" > swiftindex.temp

while IFS= read -r filename
do
  grep -o "NSLocalizedString(\"[^\")]*\", comment:\s*\"\")" "$filename" > strings.temp
  while IFS= read -r localizable
  do
    echo $localizable
    replacement=$(ruby transformToTR.rb $localizable)
    echo "$replacement"
    sed -i .bak "s/$localizable/$replacement/g" $filename
    rm "$filename.bak"

rm swiftindex.temp

transformToTR.rb

# takeas an NSLocalizedString(...) string and transforms it to the tr(...) format

localizable=ARGV[0]

def makeFirstLetterUpper(string)
  string[0].upcase + string[1..-1]
end

# remove all whitespace and "" and ,
localizable = localizable.gsub(/\s+/, "").gsub("\"", "").gsub(",", "")

# remoe leading and trailing code
localizable = localizable.gsub("NSLocalizedString(", "").gsub("comment:)", "")

# handle _ like .
localizable = localizable.gsub("\_", ".")

# uppercase first letters of every word, leaving the rest be as it is
localizable = localizable.split(".").map { |a| makeFirstLetterUpper(a) }.join("")

puts "tr(.#{localizable})"

Thanks for this! I had to change the regex string to NSLocalizedString(\"[^\")]*\", comment:\s*\"[^\"]*\") before I could get it to work, though.

Thanks! I modified your scripts to create R.swift.localizable calls: https://github.com/seasox/RswiftStringTransform
