FmtSetInt Struct Reference

#include <evo/impl/str.h>

Detailed Description

Holds integer formatting attributes.

• Used with operator<<() on String, Stream, and StreamOut
  • Each integer counts as a "field" when formatted to output object with field alignment state (like String::Format or Stream::Format)
  • See String Formatting and Stream Formatting
• This uses "unspecified" defaults, which means default attributes depend on the output object used, which uses configured formatting state or real defaults if no formatting state kept

Example

#include <evo/io.h>
#include <evo/string.h>
using namespace evo;
static Console& c = con();

int main() {
    // Format to stream
    Stream::Format(c.out) << 123 << ',' << FmtSetInt(fHEX, fPREFIX2, 4) << 10 << ',' << 20 << NL
        << FmtSetInt(fDEC, 5, '_')  << 123 << NL
        << fOCT << fPREFIX0 << 5 << ',' << 456 << NL;

    // Format same output to a string
    String str;
    String::Format(str) << 123 << ',' << FmtSetInt(fHEX, fPREFIX2, 4) << 10 << NL
        << FmtSetInt(fDEC, 5, '_')  << 123 << NL
        << fOCT << fPREFIX0 << 5 << ',' << 456 << NL;

    return 0;
}

Output:

123,0x000A,0x0014
__123
5,710

Constructor & Destructor Documentation

FmtSetInt() [1/2]

FmtSetInt ( int  base = fbCURRENT, FmtBasePrefix  prefix = fbpCURRENT, int  width = -1, char  ch = 0  )

inline

Main constructor with all attributes.

Parameters

base	Formatting base to use (see FmtBase), fbCURRENT for unspecified (default: fDEC)
prefix	Formatting prefix to use (see FmtBasePrefix), fbpCURRENT for unspecified (default: fPREFIX0)
width	Width to pad to, -1 for unspecified (default: 0)
ch	Padding character to use, 0 for unspecified (default: '0')

FmtSetInt() [2/2]

FmtSetInt ( int  base, int  width, char  ch = 0  )

inline

Short constructor without prefix.

Parameters

base	Formatting base to use (see FmtBase), fbCURRENT for unspecified (default: fDEC)
width	Width to pad to, -1 for unspecified (default: 0)
ch	Padding character to use, 0 for unspecified (default: '0')

Member Function Documentation

merge()

void merge ( const FmtSetInt &  src )

inline

Merge source attributes (used internally).

• This copies attributes from src that aren't "unspecified"

Parameters

src	Source to merge from

reset()

FmtSetInt& reset ( )

inline

Reset attributes to defaults (not unspecified).
