Qt 翻译来自非源文件的字符串 [英] Qt translate strings from non-source files

问题描述

我有一个使用 XML 文件的 Qt 项目.这些 XML 文件包含人类可读的文本，应使用 Qt 工具(lupdate、lrelease、QtLinguist)翻译这些文本.

I have a Qt project which uses XML files. Those XML files contain human-readable text and this text should be translated by using the Qt tools (lupdate, lrelease, QtLinguist).

问题是是否可以通过 lupdate 在 .ts 文件中生成条目，而无需使用 QT_TR_NOOP() 宏和朋友从源代码文件中的 XML 文件中复制字符串?或者一般来说，你如何为 Qt 项目翻译非源文件中的字符串?

The question is if it is possible to generate entries in .ts file via lupdate without duplicating the strings from the XML files in a source code file by using the QT_TR_NOOP() macro and friends? Or in general, how do you translate strings in non-source files for Qt projects?

推荐答案

我们遇到了同样的问题:包含人类可读字符串的 XML 文件.

We had the same problem : XML files containing human readable strings.

我们的解决方案是确保 XML 文件中人类可读的字符串易于提取(我们将它们放在 LABEL 属性中)，并且我们开发了一个小工具来解析 XML 文件，提取字符串，生成上下文(通过从 XML 文件中提取数据)，然后生成包含 QT_TR_NOOP() 列表的 CPP 头文件.

Our solution was to make sure that human readable strings in the XML files were easy to extract (we put them in a LABEL attribute) and we developped a small tool which would parse the XML files, extract the strings, generate a context (by extracting data from the XML file), and then generating a CPP header file containing a list of QT_TR_NOOP().

此文件已添加到 lupdate 使用的项目文件 (.pro) 中.

This file was added to our project file (.pro) that was used by lupdate.

这个解决方案对我们来说很好，但我们必须非常小心两件事:

This solution was fine for us but we had to be very careful about two things :

• 每次 XML 文件的内容更改时都运行此工具.
• 确保 XML 文件采用 UTF-8 编码.
