ddsv 0.3.0

A toy delimiter separated text parser


To use this package, run the following command in your project's root directory:

D-DSV

Toy implementation of a simplistic delimiter separated value parser library in D. Made for the purpose of getting familiar with D as a language.

Features

  • Input\ One or more lines/chunks of text.

  • Output\ Currently parses input into a multi-dimensional array of strings.

  • Controllable text delimiters\ Defaults to "

  • Controllable field delimiters\ Defaults to ,

Usage

Line by Line from stdin

import std.stdio;
import dsv;

void main(string[] args){
  Parser tsv = new ParserBuilder().fieldDelimiter('\t').build();
  string line;

  while ((line = stdin.readln()) !is null)
    tsv.parse(line);

  writeln(tsv.finish());
}
$ echo -n "foo\tbar\tfoobar\r\n\"fizz\"\t\t\"buzz\"\rping\tpong\n\tcat\t\"dog\"" | dub run
[["foo", "bar", "foobar"], ["fizz", "", "buzz"], ["ping", "pong", ""], ["", "cat", "dog"]]

Arbitrarily chunked input

import std.stdio;
import dsv;

void main(string[] args){
  Parser tsv = new ParserBuilder().fieldDelimiter('\t').build();
  string line;

  tsv.parse("foo\tbar\tfoobar\r\n\"fi");
  tsv.parse("zz\"\t\t\"buzz\"");
  tsv.parse("\rping\tpong\n\tcat\t\"dog\"\n\n\n\n");

  writeln(tsv.finish());
}
$ dub run
[["foo", "bar", "foobar"], ["fizz", "", "buzz"], ["ping", "pong", ""], ["", "cat", "dog"]]

TODO

  • Handle headers Current implementation treats headers as regular text
  • Reduce buffer reallocations:: Field string buffer is reallocated per field character
  • Clean up dsv.Parser implementation:: 'cause damn
