2018-03-12: Version 2.3 released. Changes since 2.2
Compared to the Tcllib CSV module:
MHo 2020-06-30: It is difficult to create correct CSVs for Excel: If one enters, within Excel, a manual line break within a cell and then saves a file, that line break is stored internally as 0x0a, compared to 0x0d0a for the line endings of the complete row. Ok. To create such a CSV one have to separate values in one cell with 0x0a. But as the data is written out, Tcl automatically translates this to 0x0d0a, on windows. My trick is to fconfigure the channel to lf (so nothing is translated), and in addition calling csv_write with -terminator \x0D\x0A. This produces what I want... LibreOffice, instead, always treats CSVs as expected, even if cells contain 0x0d0a (if they are enclosed in double quotes etc.). I stumbled upon the same problems in using tcllibs csv module.
