                          [-a ANDROID_RES_DIR] [-i IOS_RES_DIR]
                          [--android-resname ANDROID_RESNAME]
                          [--ios-resname IOS_RESNAME] [-s] [-f FORMAT_CONFIG]

                        resource directory for android strings (default: None)
  -i IOS_RES_DIR, --ios_res_dir IOS_RES_DIR
                        resource directory for ios strings (default: None)
  --android-resname ANDROID_RESNAME
                        filename for android resource (default: strings.xml)
  --ios-resname IOS_RESNAME
                        filename for ios resource (default: i18n.strings)
  -s, --split-files     Export sections as separate ios and android resource
                        files, comment key is used for naming new files

  -f FORMAT_CONFIG, --format-config FORMAT_CONFIG
                        excel and csv format specifications config file
                        (default: None)

Default csv and xls format specification configuration :

  "excel_sheet_reference": 0,
  "key_col": 0,
  "exportable_col": 1,
  "is_comment_col": 2,
  "comment_col": 3,
  "translations_start_col": 4,
  "exportable_value": null,
  "is_comment_value": null,
  "metadata_cols": {}
  • excel_sheet_reference: is the worksheet number (int) or name (string) for excel import
  • exportable_value: is the value to match in exportable_col to tell if the value will be exported to Android or IOS, can be a string or a list of strings, null will match True for any non empty value in the column.
  • is_comment_value: same as exportable_value to tell if the line is a comment

Example csv or xls table with default format :

key exportable is_comment comment en fr de

To generate translations for android and ios from .xlsx file :

$ update_wordings my_wordings.xlsx -i out/ios -a out/android

To generate translations from json file for android with custom resource filename :

$ update_wordings my_wordings.json -a out/android --android-resname my_strings.xml

Python interface

import mobileStrings

Read :

Function read_file(f) from module text_in supports .xls, .xlsx, .csv, .json file formats.

languages, wordings = mobileStrings.text_in.read_file('./test_translations.json')
print ', '.join(languages)
en, fr, de, pt, it, es, nl, zh, ja, pl, pt_BR, ru, id, ko, ar, tr, th, sv

Read custom formats :

For formats represented as rows like .csv and .xls, you can specify columns numbers with FormatSpec

specs = mobileStrings.text_in.FormatSpec(0, 1, 2, 3, 4, bool, bool, {}) # Default format_spec (all params are optional)

languages, wordings = mobileStrings.text_in.read_file('./test_translations.csv', specs)
print ', '.join(languages)
en, fr, de, pt, it, es, nl, zh, ja, pl, pt_BR, ru, id, ko, ar, tr, th, sv

Query :

To search a wording by its key, you can convert the list of Wording to a dict

# wordings is a list, create a dict to query
d = dict((w.key,w) for w in wordings)
print('# keys: ')
print '\n'.join(d.keys())

welcome_wording = d.get('menu.welcome')

print('\n# ' +welcome_wording.comment+':')
print welcome_wording.translations.get('fr')
print welcome_wording.translations.get('de')
# keys:

# Title on menu header:
Bienvenue !

Write :

Writing is very simple : use a write_ function from the text_out module. It supports Android, IOS, json, csv output formats.

For mobile applications :

mobileStrings.text_out.write_android_strings(languages, wordings, '~/dev/myAndProject/res')
mobileStrings.text_out.write_ios_strings(languages, wordings, '~/dev/myIOSProject/res')

Csv example :

import cStringIO
sf = cStringIO.StringIO()

# Write csv in a file-like object, for the first 3 languages only
mobileStrings.text_out.write_csv(languages[:3], wordings, sf)
print sf.getvalue()
