Transifex Command Line Tool uses Transifex iOS SDK to assist developers in pushing and pulling localizations of an iOS application (written in Swift or Objective-C) to and from Transifex CDS.
For pushing the base localization of the application, the tool uses the xcodebuild
command to export the base localization to a temporary folder, then parses the generated
.xliff file that contains all the localizable strings of the app and transforms them in the
format that CDS accepts (TXSourceString). After getting all the translated strings in the
proper format, it pushes them to CDS. For more information, look into the
Pushing section of this README.
For pulling the translated localizations, the developer must specify the locale codes and an
output folder, and the command line tool will download them, serialize them in a file
(txstrings.json) and store them in the specified folder. For more information, look into
the Pulling section of this README.
Developer can also use the invalidate command to force CDS cache invalidation so
that the next pull command will fetch fresh translations from the CDS.
The token and secret strings can be provided by the developer either as arguments in the
command line tool or as enviroment variables (TRANSIFEX_TOKEN, TRANSIFEX_SECRET).
You can either use the tool by typing: swift run txios-cli in the root directory of
the project, or you can install the executable to /usr/local/bin directory so that you can
call it from any folder.
In order to copy the executable, you can first build the project with
swift build -c release and then copy it with
cp .build/release/txios-cli /usr/local/bin/txios-cli.
The following calls can be either made from within the TXCli project directory by:
swift run txios-cli <cli command>
or after following the installation instructions above, from any folder of your computer by:
txios-cli <cli command>.
Bear in mind that due to naming collision, the --verbose flag won't be detected if the
txios-cli is executed via the swift run command, as the flag will be applied on the
swift executable instead. So to avoid collisions like this, it's recommended to execute
txios-cli directly after building it.
For simplicity the following examples will use the latter command.
txios-cli, txios-cli -h, txios-cli --help
Displays helpful information for the CLI tool and lists all the subcommands.
txios-cli [subcommand] --help
or
txios-cli help [subcommand]
Displays helpful information for a subcommand and lists all of its options.
txios-cli push --token <transifex_token> --secret <transifex_secret> --project MyApp.xcodeproj
Exports the base localization of the provided Xcode project, parses the generated XLIFF file, transforms the translation units to the format Transifex accepts and pushes them to the Transifex server.
If the developer has already set the enviroment variables mentioned above, then this command can be simplified to:
txios-cli push --project MyApp.xcodeproj
With the --excluded-files option in the push command, an optional list of filenames can be excluded from processing.
Developers can offer a space separated list of filenames that must be filtered out by the CLI before the strings are pushed to CDS.
Example:
txios-cli push ... --excluded-files ExcludedFile1.strings ExcludedFile2.strings
Note: If a string is included both in the excluded filenames and is also found in non-excluded filenames, it will be included in the push data.
By default, the txios-cli tool will hash the key of each source string that
is about to be pushed to CDS.
If the developer prefers to maintain the original keys as they already exist in
the application, they can provide the --disable-hash-keys option.
The keys are always printed to the console when the --verbose option is active.
Example:
txios-cli push --project MyApp.xcodeproj --verbose
Pushing translations to CDS: [
"hashkey1": "string1"
,
"hashkey2": "string2"
]...
txios-cli push --project MyApp.xcodeproj --verbose --disable-hash-keys
Pushing translations to CDS: [
"string key 1": "string1"
,
"string key 2": "string2"
]...
The txios-cli tool calls the xcodebuild process to export the localizations
using the -exportLocalizations option. When that happens, the system automatically
picks the base SDK to be used (iphoneos, macosx etc).
There have been cases where the base SDK is not picked up correctly by the xcodebuild
process and a specific base SDK needs to be provided externally.
If the push command fails with errors like "no such module 'UIKit'", the developer
can manually specify the base SDK to be used using the --base-sdk option of the push
command. For example, for iOS applications the option can be set to --base-sdk iphoneos.
Currently (version 0.1.0) pluralization is supported but only for cases where one variable is used per pluralization rule. More advanced cases such as nested pluralization rules (for example: "%d out of %d values entered") will be supported in future releases.
Also, at the moment of writing (version 0.1.0), the .stringsdict specification only supports
plural types (NSStringPluralRuleType) which is the only possible value of the
NSStringFormatSpecTypeKey key (Ref).
If more rule types are added in the .stringsdict specification, the XLIFF parser must be
updated in order to be able to extract them properly and to construct the ICU format out
of them.
Width Variants in .stringsdict files are also not currently supported (Ref).
txios-cli pull --token <transifex_token> --translated-locales <translated_locale_list> --output <output_directory>
Downloads the localizations from Transifex CDS for the specified translated locales, stores
them in a txstrings.json file to the output directory specified.
If the developer has already set the enviroment variables mentioned above, then this command can be simplified to:
txios-cli pull --translated-locales <translated_locale_list> --output <output_directory>
txios-cli invalidate --token <transifex_token>
Forces CDS cache invalidation so that the next pull command will fetch fresh translations
from CDS.
If the developer has already set the enviroment variable mentioned above, then this command can be simplified to:
txios-cli invalidate
