Introduction

Crowdin CLI uses a YAML configuration file that contains a description of the resources to manage: files to be uploaded into Crowdin and the locations of the corresponding translations.

To use Crowdin CLI, you should first generate your configuration file and then run the tool. By default, Crowdin CLI looks for a configuration file named crowdin.yaml (so you don’t have to specify the file name unless it’s different from crowdin.yaml).

To create the configuration file run the following command:

$ crowdin generate

Configuration File Structure

A valid Crowdin CLI YAML configuration file has the following structure, so please make sure that you fill out all the needed information:

  • Head of the file with project credentials, preferences, and access information
  • One files array element that describes a set of source and translation files you will manage
  • Required fields in the files array: Source that defines filters for the source files and Translation with instructions on where to store the translated files or where to look for translations you already have if you want to upload them while setting up the CLI

See API Integration Setup article to learn where to find your project credentials.

Writing a Simple Configuration File

A typical YAML configuration file looks similar to the following:

"project_identifier": "your-project-identifier"
"api_key": "54e01e81--your-api-key--f6a2724a"                                   #can be found in your project settings page
"base_path": "/home/office/source-code"

"files": [
  {
    "source" : "/resources/en/*.json",                                          #source files filter
    "translation" : "/resources/%two_letters_code%/%original_file_name%"        #where translations are stored
  }
]

Note: On Windows, if you use Windows-style directory separator, it should be doubled according to the YAML syntax:

{
"source" : "\\resources\\en\\*.json",
"translation" : "\\resources\\%two_letters_code%\\%original_file_name%"
}

To run the above configuration file and upload source files to Crowdin:

$ crowdin upload sources

Get translations from Crowdin and put them to the right places:

$ crowdin download

API Credentials from Environment Variables

You could load the API Credentials from an environment variable, for example:

"api_key_env": CROWDIN_API_KEY
"project_identifier_env": CROWDIN_PROJECT_ID
"base_path_env": CROWDIN_BASE_PATH

If mixed, api_key and project_identifier are prioritized:

"api_key_env": CROWDIN_API_KEY            # Low priority
"project_identifier_env": CROWDIN_PROJECT # Low priority
"base_path_env": CROWDIN_BASE_PATH        # Low priority
"api_key": "xxx"                          # High priority
"project_identifier": "yyy"               # High priority
"base_path": "zzz"                        # High priority

Split Project Configuration and API Credentials

The crowdin.yaml file contains a description of the resources to manage and API credentials (api_key, project_identifier, base_path). This means that it is unsafe to commit this file into the code repository because the API key would be accessible to other users. Crowdin CLI supports 2 types of configuration files:

  • a description of the resources to manage, residing in the project directory
  • API credentials, probably residing in $HOME/.crowdin.yaml

Note: API credentials from .crowdin.yaml configuration file are of higher priority than credentials from project directory(crowdin.yaml).

If you need to run a command with user-specific credentials (for example upload sources) then run the following command:

$ crowdin upload sources --identity 'path-to-user-credentials-file'

But if user-specific credentials file residing in $HOME/.crowdin.yaml you can simply run:

$ crowdin upload sources

General Configuration

The sample configuration provided above has source and translation attributes containing standard wildcards (also known as globbing patterns) to make it easier to work with multiple files.

Here are patterns you can use:

* (asterisk)

Represents any character in file or directory name. If you specify a “*.json” it will include all files like “messages.json”, “about_us.json” and anything that ends with “.json”.

** (doubled asterisk)

Matches any string recursively (including sub-directories). Note that you can use ** in both source and translation patterns. When using ** in the translation pattern, it will always contain sub-path from source for a certain file. For example, you can use source: ‘/en/**/*.po’ to upload all *.po files to Crowdin recursively. The translation pattern will be ‘/%two_letters_code%/**/%original_file_name%’.

? (question mark)

Matches any single character.

[set]

Matches any single character in a set. Behaves exactly like character sets in Regexp, including set negation ([^a-z]).

\ (backslash)

Escapes the next metacharacter.

Placeholders

Crowdin CLI allows to use the following placeholders to put appropriate variables into the resulting file name:

Name Description
%language% Language name (i.e. Ukrainian)
%two_letters_code% Language code ISO 639-1 (i.e. uk)
%three_letters_code% Language code ISO 639-2/T (i.e. ukr)
%locale% Locale (like uk-UA)
%locale_with_underscore% Locale (i.e. uk_UA)
%original_file_name% Original file name
%android_code% Android Locale identifier used to name "values-" directories
%osx_code% OS X Locale identifier used to name ".lproj" directories
%original_path% Use names of the parent folders in Crowdin project to build a file path in the resulted bundle
%file_extension% Original file extension
%file_name% File name without extension

You can also define the path for files in the resulting archive by putting a slash (/) at the beginning of the pattern.

Your translation option may look like: “/locale/%two_letters_code%/LC_MESSAGES/%original_file_name%”.

Usage of Wildcards

Structure of files and directories on the local machine:

- base_path
      |
      |-- folder
      |     |
      |     |-- 1.xml
      |     |-- 1.txt
      |     |-- 123.txt
      |     |-- 123_test.txt
      |     |-- a.txt
      |     |-- a1.txt
      |     |-- crowdin?test.txt
      |     |-- crowdin_test.txt
      |
      |-- 1.xml
      |-- 1.txt
      |-- 123.txt
      |-- 123_test.txt
      |-- a.txt
      |-- a1.txt
      |-- crowdin?test.txt
      |-- crowdin_test.txt
      |-- 3.txt

Example 1. Usage of wildcards in the source path:

#........your project configuration........
"files" : [
  {
    "source" : "/**/?[0-9].txt", #upload a1.txt, folder/a1.txt
    "translation" : "/**/%two_letters_code%_%original_file_name%"
  },
  {
    "source" : "/**/*\\?*.txt", #upload crowdin?test.txt, folder/crowdin?test.txt
    "translation" : "/**/%two_letters_code%_%original_file_name%"
  },
  {
    "source" : "/**/[^0-2].txt", #upload 3.txt, folder/3.txt, a.txt, folder/a.txt (ignore 1.txt, folder/1.txt)
    "translation" : "/**/%two_letters_code%_%original_file_name%"
  }
]

Example 2. Usage of wildcards for ignoring files:

#........your project configuration........

"files": [
  {
    "source" : "/**/*.*", #upload all files that  the base_path contains
    "translation" : "/**/%two_letters_code%_%original_file_name%",
    "ignore" : [
      "/**/%two_letters_code%_%original_file_name%", #ignore the translated files
      "/**/?.txt",                                   #ignore 1.txt, a.txt, folder/1.txt, folder/a.txt
      "/**/[0-9].txt",                               #ignore 1.txt, folder/1.txt
      "/**/*\\?*.txt",                               #ignore crowdin?test.txt, folder/crowdin?test.txt
      "/**/[0-9][0-9][0-9].txt",                     #ignore 123.txt , folder/123.txt
      "/**/[0-9]*_*.txt"                             #ignore 123_test.txt, folder/123_test.txt
    ]
  }
]

Language Mapping

Often software projects have custom names for locale directories. Crowdin CLI allows you to map your own languages to be recognizable for Crowdin.

Let’s say your locale directories are named ‘en’, ‘uk’, ‘fr’, ‘de’. All of them can be represented by the %two_letters_code% placeholder. Still, you have one directory named ‘zh_CH’. In order to make it work with Crowdin CLI without changes in your project, you can add a languages_mapping section to your file set.

Sample configuration:

#........your project configuration........

"files" : [
  {
    "source" : "/locale/en/**/*.po",
    "translation" : "/locale/%two_letters_code%/**/%original_file_name%",
    "languages_mapping" : {
      "two_letters_code" : {
        "ru" : "ros",
        "uk" : "ukr"
      }
    }
  }
]

Mapping format is the following: “crowdin_language_code” : “code_you_use”. Check the full list of Crowdin language codes that can be used for mapping.

You can also override language codes for other placeholders like %android_code%, %locale% etc.

Renaming Translations File

If you need to rename a file with translations after the export, you can easily do this with the help of the parameter translation_replace.

For example, if the file is named “strings_en.xml” it can be renamed to “strings.xml”. For this, add a new parameter (at the same level as the translation parameter) to the configuration file (crowdin.yaml):

translation_replace: {
    "_en" : ""
}

In this case, “_en” will simply be erased from the file name.

Ignoring Files and Directories

From time to time there are files and directories you don’t need to translate in Crowdin. In such cases, local per-file rules can be added to the config file in your project.

"files": [
  {
    "source" : "/**/*.properties",
    "translation" : "/**/%file_name%_%two_letters_code%.%file_extension%",
    "ignore" : [
      "/test/file.properties",
      "/example.properties"
    ]
  },
  {
    "source" : "/locale/en/**/*.po",
    "translation" : "/locale/%two_letters_code%/**/%original_file_name%",
    "ignore" : [
      "/locale/en/templates",
      "/locale/en/workflow"
    ]
  }
]

Multicolumn CSV

If a CSV file contains the translations for all target languages, you should specify appropriate language codes in the scheme.

CSV file example:

identifier,source_phrase,context,Ukrainian,Russian,French
ident1,Source 1,Context 1,,,
ident2,Source 2,Context 2,,,
ident3,Source 3,Context 3,,,

Configuration file example:

"files" : [
  {
    "source" : "multicolumn.csv",
    "translation" : "multicolumn.csv",
    "first_line_contains_header" : true,
    "scheme" : "identifier,source_phrase,context,uk,ru,fr"
  }
]

Saving Directory Structure on Server

"preserve_hierarchy": true

Example of file configuration using the preserve_hierarchy option:

"project_identifier": "test"
"api_key": "KeepTheAPIkeySecret"
"base_url": "https://api.crowdin.com"
"base_path": "/path/to/your/project"
"preserve_hierarchy": true

"files" : [
  {
    "source" : "/locale/en/**/*.po",
    "translation" : "/locale/%two_letters_code%/**/%original_file_name%"
  }
]

By default, directories that do not contain any files for translation will not be created in Crowdin. For example:

- locale
    |
    |-- en
        |
        |-- foo.po
        |-- bar.po

By default, project files will be represented in Crowdin as following:

- foo.po
- bar.po

Using the option preserve_hierarchy, file structure in Crowdin will be the following:

- en
  |
  |-- foo.po
  |-- bar.po

Uploading Files to Specified Path with Specified Type

This feature adds support for 2 optional parameters in the yaml file section: dest and type. This is typically used for projects, where the uploaded name must be different, so Crowdin can detect the type correctly. The dest parameter allows you to specify a file name in Crowdin.

Note! The dest parameter only works for single files

Example of the configuration file with both parameters:

"project_identifier": "your-project-identifier"
"api_key": "54e01e81--your-api-key--f6a2724a"           #can be found in your project settings page
"base_path": "/home/office/source-code"

"files" : [
  {
    "source" : "/conf/messages",
    "dest" : "/messages.properties",
    "translation" : "/conf/messages.%two_letters_code%",
    "type" : "properties"
  },
  {
  "source" : "/app/strings.xml",
  "dest" : "/strings.xml",
  "translation" : "/res/values-%android_code%/%original_file_name%"
  }
]

Changed Strings Update

The parameter update_option is optional. If it is not set, translations for changed strings will be lost. Useful for typo fixes and minor changes in source strings.

Depending on the value, update_option is used to preserve translations and preserve/remove validations of changed strings during file update.

The values are:

  • update_as_unapproved - preserve translations of changed strings and remove validations of those translations if they exist
  • update_without_changes - preserve translations and validations of changed strings

Example of the configuration file with update_option parameter:

"project_identifier": "your-project-identifier"
"api_key": "54e01e81--your-api-key--f6a2724a"           #can be found in your project settings page
"base_path": "/home/office/source-code"

"files" : [
  {
    "source" : "/*.csv",
    "translation" : "/%three_letters_code%/%file_name%.csv",
    "first_line_contains_header" : true,
    "scheme" : "identifier,source_phrase,translation,context",
    "update_option" : "update_as_unapproved"
  },
  {
    "source": "/**/*.xlsx",
    "translation" : "/%three_letters_code%/folder/%file_name%.xlsx",
    "update_option" : "update_without_changes"
  }
]

Translations Upload

The command upload translations uploads existing translations to Crowdin. If no options specified, uploaded translations will be imported even if they are duplicated or if they are equal with the source strings, and will not be approved.

The values are:

  • -l, –language=language_code - defines the language translations that should be uploaded to Crowdin. By default, translations are uploaded to all project’s target languages. (Crowdin Language Codes)
  • –[no-]import-duplicates - defines whether to add translation if there is the same translation already existing in Crowdin project
  • –[no-]import-eq-suggestions - defines whether to add translation if it is equal to source string in Crowdin project
  • –[no-]auto-approve-imported - automatically approves uploaded translations

Additional Options for XML Files

translate_content
optional
bool Defines whether to translate texts placed inside the tags. Acceptable values are: 0 or 1. Default is 1.
translate_attributes
optional
bool Defines whether to translate tags' attributes. Acceptable values are: 0 or 1. Default is 1.
content_segmentation
optional
bool Defines whether to split long texts into smaller text segments. Acceptable values are: 0 or 1. Default is 1.
Important! This option disables the possibility to upload existing translations for XML files when enabled.
translatable_elements
optional
array This is an array of strings, where each item is the XPaths to DOM element that should be imported.
Sample path: /path/to/node or /path/to/attribute[@attr]
Note! If defined, the parameters translate_content and translate_attributes are not taken into account while importing.

Example of the configuration file with additional parameters:

"project_identifier": "your-project-identifier"
"api_key": "54e01e81--your-api-key--f6a2724a"           #can be found in your project settings page
"base_path": "/home/office/source-code"

"files" : [
  {
    "source" : "/app/sample1.xml",
    "translation" : "/app/%locale%/%original_file_name%",
    "translate_attributes" : 1,
    "translate_content" : 0
  },
  {
    "source" : "/app/sample2.xml",
    "translation" : "/app/%locale%/%original_file_name%",
    "translatable_elements" : [
      "/content/text",             # translatable texts are stored in "text" nodes of parent node "content"
      "/content/text[@value]"      # translatable texts are stored in "value" attribute of "text" nodes
    ]
  }
]

Escape Quotes Options for .properties File Format

Defines whether a single quote should be escaped by another single quote or backslash in exported translations. You can add escape_quote per-file option. Acceptable values are: 0, 1, 2, 3. Default is 3.

The values are:

  • 0 - do not escape single quote
  • 1 - escape single quote by another single quote
  • 2 - escape single quote by a backslash
  • 3 - escape single quote by another single quote only in strings containing variables ( {0} )

Example of the configuration file:

"project_identifier": "your-project-identifier"
"api_key”: "54e01e81--your-api-key--f6a2724a"           #can be found in your project settings page
"base_path”: "/home/office/source-code"

"files" : [
  {
    "source" : "/en/strings.properties",
    "translation" : "/%two_letters_code%/%original_file_name%",
    "escape_quotes" : 1
  }
]

Configuration File for VCS Integrations

VCS integrations require the same configuration file as the CLI tool, meaning the same structure is supported. The only difference, is that the project credentials should not be stored in the file header for security reasons. Also, two additional parameters can be used.

Commit Message Parameter for VCS Integrations

Each time translations are commited the default message is shown “New translations {fileName} ({languageName})”. You can use commit_message parameter to add Git tags, in order to skip builds, add tests, and more.

Example:

"base_path": "/home/office/source-code"
"commit_message": "[ci skip]"                
"files": [
  {
    "source" : "/resources/en/*.json",                                          #source files filter
    "translation" : "/resources/%two_letters_code%/%original_file_name%"        #where translations are stored
  }
]

Export Languages Parameter for VCS Integrations

By default, all the languages are exported. If you need to export some specific languages, use export_languages paramenter to specify them.

Example:

"base_path": "/home/office/source-code"
"export_languages": [                                   
    "ru", 
    "uk", 
    "ja"
  ]
"files": [
  {
    "source" : "/resources/en/*.json",                                          #source files filter
    "translation" : "/resources/%two_letters_code%/%original_file_name%"        #where translations are stored
  }
]
