summary:: file reader for space-delimited text files
related:: Classes/File
categories:: Files
description::
FileReader reads space-delimited text files into 2D arrays line by line.
For tab delimited files use link::Classes/TabFileReader::. For semi-colon-delimited files use link::Classes/SemiColonFileReader::. For comma-separated files use link::Classes/CSVFileReader::.
Examples::
code::
(
// 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;
