Detailed Description

The format that prints the version to std::cout.

The version printing is not done immediately, because the user cannot provide meta information on construction of the parser. Thus the meta information is collected and only evaluated when calling format_version::parse().

Remarks

For a complete overview, take a look at Parser

Member Function Documentation

parse()

void sharg::detail::format_version::parse ( parser_meta_data & parser_meta )

inline

Initiates the printing of the version information to std::cout.

Parameters

[in]

parser_meta

The meta information that are needed for a detailed version information.
