boost :: program_options - 如何处理INI文件中具有相同名称的多个节 [英] boost::program_options - how to handle multiple sections with the same name in INI file

问题描述

在下面的配置中;是有办法处理个别部分。

我正在寻找一种可靠的方式来验证下面的服务器部分。

  [basic] 
 number_of_servers = 3 
 
 [server] 
 ip = 10.20.30.40 
 password = sdfslkhf 
 
 [server] 
 ip = 10.20.30.41 
 password = sdfslkhf 
 
 [server] 
 ip = 10.20 .30.42 
 password = sdfslkhf 
 
 [server] 
 password = sdfslkhf 
 
 [server] 
 ip = 10.20.30.42 $ b $当使用 boost :: program_options 时，   code>来解析INI文件，选项名称​​必须以它们的封闭节名称为前缀。
 
 
 
换句话说，节是选项标识符的一部分，但我不认为您有办法识别哪个节给出 server.ip 变量属于（因此，它是关联的 server.password ）。
 
 
 
我认为你应该考虑 Boost.PropertyTree （也支持INI文件解析）。
 
In a config like below; is there a way to handle individual sections.

I am looking for a way to validate individual "server" sections below, in a reliable manner.
[basic]
number_of_servers=3

[server]
ip=10.20.30.40
password=sdfslkhf    

[server]
ip=10.20.30.41
password=sdfslkhf

[server]
ip=10.20.30.42
password=sdfslkhf

[server]
password=sdfslkhf

[server]
ip=10.20.30.42

解决方案
When using boost::program_options to parse a INI file, the option names must be prefixed by their enclosing section names.

In other words, sections are part of the option 'identifier', but I don't think you have a way to identify to which section a given server.ip variable belongs (and thus, which is the associated server.password).

I think you should consider Boost.PropertyTree (which also supports INI file parsing) for this task.
