lproj2es

lproj2es is a utility to extract all localized strings *.lproj/*.strings into an ElasticSearch index for easy look-up. This allows translators to produce localizations using terms from endorsed by Apple.

Loading the iOS root filesystem

1. Download an IPSW from https://ipsw.me. IPSWs nowadays are typically over 2 GB in size, so make sure you have got enough time to download the file, and enough harddisk space to store and unzip it.

2. Unzip the IPSW to extract the root filesystem image (the filenames vary between iOS versions).

   $ unzip iPhone_7Plus_10.3.1_14E304_Restore.ipsw 058-55433-171.dmg

3. Attach the image.

   $ open 058-55433-171.dmg

Building the index

1. Start the ElasticSearch cluster. We assume ElasticSearch is accessible via http://127.0.0.1:9200.

2. Run the program. It typically takes less than 3 minutes to finish with ElasticSearch on the local machine.

   $ ./lproj2es /Volumes/Erie14E304.D11D111OS/

Document structure

The indexed translations are stored in the localizations index with ios type, using 1 replica and 1 shard. Each document looks like:

{
    "BUNDLE": "/Volumes/Erie14E304.D11D111OS/System/Library/CoreServices/SpringBoard.app",
    "FILE": "SpringBoard.strings",
    "KEY": "AWAY_LOCK_LABEL",
    "en_US": "slide to unlock",
    "fr_FR": "Déverrouiller",
    "es_ES": "Deslizar para desbloquear",
    "de_DE": "Entsperren",
    ...
}

The BUNDLE field specifies the bundle the translation belongs to. The FILE field gives the *.strings file that contains the translation. The document encodes a single key-value entry in the *.strings file, with the key in the KEY field, and values in their respective locale-id field (en_US, fr_FR, etc.)
