Pixxxer

Installation

Installation is super easy. Gems works like that.

gem install pixxxer

Usage

Pixxxer provide a simple DSL for defining fixed with data and then extensions to String and Hash to build and parse those records. It can handle floats, integers, and strings.

Assuming a record like this:

Title     Author    Qty  Price
-----     ------    ---  -----
Dune      Herbert   0012001295
012345678901234567890123456789
          1         2

You can define the follwing template:

define_pixxx_template(:book)
    .add_field(:title).as_string.at_position(0).with_width(10).and
    .add_field(:author).as_string.at_position(10).with_width(10).and
    .add_field(:quantity).as_integer.at_position(20).with_width(5).and
    .add_field(:price).as_float.at_position(25).with_width(5).with_precision(2)

To use the template to parse:

record = 'Dune      Herbert   0012001295'.pixxxit(:book)
record[:title].should == 'Dune      '
record[:author].should == 'Herbert    '
record[:quantity].should == 120
record[:price].should == 12.95

To use the template to build a record:

s = record.depixxxit(:book)
s.should == 'Dune      Herbert   0012001295'

Note:

  • Most things default to zero
  • Fields default to strings
  • at_position is zero-based
