char delimiter = '\t'

)

const string filename

)

Return Value

Type: void

Examples

// Load a text file with three numeric columns,
// Store the tuple in an array
// (NOTE: this is a naive, inefficient way to populate an array, see NOTES)
alias Tuple!(int,int,int) T;
T[] t;
tabular!( T,           // The number and types of the (expected) fields in the file
delegate(x)
{ t ~= x; }, // for each line read, call this function. X will be of type T.
'\t'         // The delimiter (default = TAB)
)("file.txt"); // The file name to read.

// Load a text file with three numeric columns,
// Use the second column as a KEY and the third column as the VALUE.
alias Tuple!(int,int,int) T;
int[int] data;
tabular!( T,              // The number and types of the (expected) fields in the file
delegate(x)
{   // for each line read, call this function. X will be of type T.
data[x[1]] = x[2] ;
},
'\t'             // The delimiter (default = TAB)
)("file.txt");    // The file name to read.
