TabFileReader reads tab/return delimited files into 2D arrays.
|
||
|
|
|
||
|
|
For semi-colon-delimited files use link::Classes/SemiColonFileReader::. 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("TabDelTest.sc", "w");
|
||
|
|
f.write(
|
||
|
|
"Some tab- delimited items in line 1
|
||
|
|
|
||
|
|
and then some more in line 3
|
||
|
|
"
|
||
|
|
