SemiColonFileReader reads semi-colon delimited files into 2D arrays.
|
||
|
|
|
||
|
|
For tab delimited files use link::Classes/TabFileReader::. For comma-separated files use link::Classes/CSVFileReader::. For space-delimited files, or custom delimiters, use link::Classes/FileReader::.
|
||
|
|
|
||
|
|
Examples::
|
||
|
|
|
||
|
|
code::
|
||
|
|
(
|
||
|
|
// write a test file:
|
||
|
|
f = File("SemiColonTest.sc", "w");
|
||
|
|
f.write(
|
||
|
|
"Some semi-colon delimited data;
|
||
|
|
|
||
|
|
123;;4;
|
||
|
|
0.5;0.6;0.7
|
