是否有C ++的C ++跨平台键/值API或库？

Question

We want to persist some user settings int he GUI part of our code. I used to do Win32 programming exclusively and the typical way this was done was with registry settings.

I assume that this should be done with configuration files, but was wondering if there was a library or cross platform wrapper that made key/value pair persistence very easy.

Answer 1

Qt's QSettings class handles this:

Answer 2

Boost.PropertyTree支持XML，JSON，INI配置文件。

Answer 3

There is also JSON for a lighter alternative of XML. Lots of implementations on that page too.

Answer 4

Qt 4 has a class for it, named QSettings . Looks exactly like what you need.

Answer 5

Why not use an XML as the configuration file. Then you only have to find a cross platform XML library which is easier IMO. Here is a list of nice XML parsing solutions for C++.

Answer 6

想到老派Berkley DB 。

Answer 7

看看Tokyo Cabinet或Embedded InnoDB 。

Answer 8

In the old days we used .ini files in windows. Here is a portable version of an ini file read/write library
It will work on Windows as well as Linux.
