[ANN] Guile-DSV 0.3.0 released

[Artyom V. Poptsov]

Hello Guilers,

I'm pleased to announce Guile-DSV 0.3.0:
  https://github.com/artyom-poptsov/guile-dsv/releases/tag/v0.3.0

Thanks to Alex Sassmannshausen who found and reported bugs in RFC4180
format parser.


* What is Guile-DSV?

Guile-DSV is a library that allows to parse Delimiter-Separated Values
format (DSV).  It supports two flavors of DSV: Unix-style[1] and RFC4180[2].

Also Guile-DSV is shipped with a program named "dsv" that allows to read
and process DSV format (including delimiter change and conversion from
one standard to another.)  See README file for usage examples.


* List of user visible changes

Here's an excerpt from the NEWS file:

* Changes in version 0.3.0 (2020-05-11)
** Remove bundled SRFI-64
   This module is shipped with Guile since version 2.0.12.
** Improve =dsv= tool (=utils/dsv.in=)
   - The tool now is capable of converting delimiters and reading data
     from stdin.
   - Add check for empty argument: print help message if no arguments
     specified.
** Bugfixes
*** Fix quote handling in RFC4180 data
    The library would always fail to correctly parse RFC4180 format
because there
    was an error in the state machine: it considered even number of
    double quotes as a proof that the input data was correct.

    This change fixes the problem (#7 on GitHub) by re-writing the FSM
    to follow the standard more closely. Also now the FSM for RFC4180
    reads data character by character which is more elegant and
    controllable.

    Thanks to Alex Sassmannshausen for attracting my attention to the
    parser issues in
      <https://github.com/artyom-poptsov/guile-dsv/issues/7>
** Improve tests
   Expand test suite, make tests more fine-grained.

Thanks and happy hacking!
