CSVFileReader

reads comma-separated text files into 2D arrays line by line.

Use TabFileReader for tab delimited files,

and FileReader for space-delimited files, or custom delimiters.

*read(path, skipEmptyLines, skipBlanks, func)

(

// write a test file:

f = File("CSVReadTest.sc", "w");

f.write(

"Some,comma,delimited,items, in line 1

and then, some more, with several commas,,,, in line 3

"

);

f.close;

)

// open file, read and put strings into array, close file.

x = CSVFileReader.read("CSVReadTest.sc").postcs;

// can skip empty lines:

x = CSVFileReader.read("CSVReadTest.sc", true).postcs;

// can skip blank entries caused by multiple commas :

x = CSVFileReader.read("CSVReadTest.sc", true, true).postcs;

// do file open/close by hand if you prefer:

f = File("CSVReadTest.sc", "r"); f.isOpen;

t = CSVFileReader(f);

t.read(true, true).postcs;

f.close;

(

// write a test file with numbers:

f = File("CSVReadTestNum.sc", "w");

(1..10).do { |n| f.write(n.asString ++ ","); };

f.close;

)

x = CSVFileReader.read("CSVReadTestNum.sc", true, true).postcs;

x.collect(_.collect(_.interpret)); // convert to numbers.

// or do it immediately:

x = CSVFileReader.readInterpret("CSVReadTestNum.sc").postcs;

(

// write a test file with several lines of numbers:

f = File("CSVReadTestNum.sc", "w");

(1..100).do { |n|

f.write(n.asString ++ if (n % 10 != 0, ",", Char.nl)); };

f.close;

)

x = CSVFileReader.readInterpret("CSVReadTestNum.sc", true, true).postln;
