Text Parser problem

[CDavis]

I have a code that I have to rewrite or rework and not really sure where to start

I know I have to work in text phaser but unsure of the direction

You could do something like this:

enum keyword_t { LOCAL_TIME, WEATHER, TEMP_STRING, HUMIDITY, WIND, PRESSURE, PRESSURE_TREND, HEAT_INDEX, NOWCAST, UNKNOWN };
keyword_t keyword ;
bool getNowCast = true ;

void noteKeyword( const std::string& token )
{
    static const std::unordered_map< std::string, keyword_t > lookup = // #include <unordered_map>
    {
        { "local_time_rfc822", LOCAL_TIME },
        { "weather", WEATHER },
        { "temperature_string", TEMP_STRING },
        { "relative_humidity", HUMIDITY },
        { "wind_string", WIND },
        { "pressure_in", PRESSURE },
        { "pressure_trend", PRESSURE_TREND },
        { "heat_index_string", HEAT_INDEX },
        { "nowcast", NOWCAST },
    };

    const auto iter = lookup.find(token) ;
    if( iter != lookup.end() ) keyword = iter->second ;
    else keyword = UNKNOWN ;

    if( keyword == NOWCAST && !getNowCast ) keyword = UNKNOWN ;
}

Adding an overload for std::string would be the simpler solution.
+ Guarantees behaviour identical to the current code; regressions are not required
- C++ code is easier to maintain.

void noteKeyword ( char* token ) { /* current code */ } ;

// EDIT: corrected by firedraco
void noteKeyword( const std::string& token ) { return noteKeyword( token.c_str() ) ; }

[firedraco]

void noteKeyword( const std::string& token ) { return token.c_str() ; }

Did you mean:

void noteKeyword( const std::string& token ) { noteKeyword(token.c_str()); }

Yes, thanks!.

Wow I like that solution but other than text parser isn't there an easier way cause really it just looks like the strcmp is wrong but unsure what to put there instead
