Translation Management

Placeholders (Strings)

Content is machine translated from English by Phrase Language AI.

Common placeholder formats that can be used in many localization file formats.

When selecting the correct placeholder format for a project:

  • Placeholders are highlighted in the editor window and can be checked and validated for presence in the translation.

  • Placeholders are automatically escaped when ordering translations and will not be modified by an external translator.

Enabling placeholder styles in your project

When creating or editing a project, specify the placeholder formats within the Placeholders tab. Select all required format styles and see all matching placeholders highlighted immediately when working with in the editor and In-Context-Editor.

Placeholder conversion

Placeholder conversion is an attempt to reduce translation workload on multi-platform development. If developing on multiple mobile platforms with the intention to share translations between platforms and don’t want to maintain a separate project for each platform, placeholder conversion helps accomplish that. Whenever downloading a locale the application or via API, choose the convert placeholder format option. This format option can also be activated in the .phrase.yml configuration file. Placeholders in translations are converted to match format specific requirements.

Placeholder conversion is only available for the following localization file formats (placeholder conversion is limited to Android XML and iOS strings string format specifiers (cstyle placeholder style)):
