[Quickfix-developers] RFE: Configuration file should allow environment variable references

[Joerg T. <Joe...@ma...>]

Hi,

it would be nice to have the following in the configuration file:

DataDictionary=${FIX_SPEC_DIR}/FIX42.xml

while ${name} syntax refers to an environment variable FIX_SPEC_DIR. This make the
Configuration files more flexible.

In the operator>>() method of Settings:

      79       case ConfigLexer::LC_STATE_VALUE:
      80       std::string value = lexer.YYText();
      81       std::string::size_type pos = value.find_last_not_of( ' ' );
      82       if ( pos == std::string::npos ) continue;
      83       value.resize( pos + 1 );
      84       ( *currentSection ).setString( currentName, value );
      85       break;

after line 80 there could be a function expandEnvironmentVariable to interpolate
the references.

Cheers, Jörg
