FileReader

reads space-delimited text files into 2D arrays line by line.

Use TabFileReader for tab delimited files, 

and CSVFileReader for comma-separated files.

*read(path, skipEmptyLines, skipBlanks, func, delimiter)

(

// write a test file:

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

f.write(

"Some space delimited items in line 1

and then some more with several blanks     in line 3

"

);

f.close; 

)

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

x = FileReader.read("FileReaderTest.sc").postcs;

// can skip empty lines: 

x = FileReader.read("FileReaderTest.sc", true).postcs;

// can skip blank entries caused by multiple spaces : 

x = FileReader.read("FileReaderTest.sc", true, true).postcs;

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

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

t = FileReader(f, true, true);

t.read;

f.close;

// take letter "a" as delimiter: 

x = FileReader.read("FileReaderTest.sc", true, true, delimiter: $a).postcs;

(

// write a test file with numbers:

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

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

f.close; 

)

x = FileReader.read("FileReadTestNum.sc").postcs;

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

// or do it immediately:

x = FileReader.readInterpret("FileReadTestNum.sc").postcs;

(

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

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

(1..100).do { |n| 

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

f.close; 

)

x = FileReader.readInterpret("FileReadTestNum.sc", true, true).postln;
