Ruby Reports (Ruport) 0.6.0

= Ruport 0.6.0 Release, the “That Guy” edition =

== What is Ruport? ==

Ruby Reports is a software library that aims to make the task of
reporting less tedious and painful. It provides tools for data
acquisition, database interaction, formatting, and parsing/munging.

Ruby Reports provides solid support for processing and formatting all
sorts tabular data. It also includes tools to help with more
specialized things such as graphing and invoice generation. It is
highly extensible, so making it fit your particular needs should be
easy.

== Quick Summary of Release ==

This release features a number of new features, some performance
enhancements, and several bug fixes. Ruport now has additional data
grouping and manipulation tools, a new LaTeX plugin for rendering
tables, and support for timeouts and exception handling in our report
runner. Additionally, full support for ERb within SQL queries was
added.

For more info, see detailed release notes below.

== Installation ==

Ruport and its dependencies can easily be installed via rubygems:

gem install ruport

If you have trouble or want to try installing manually, see our install
guide:

== Project News ==

  • I gave a talk at RubyConf 2006 about Ruport without getting booed off
    stage!
    Slides and a short article available here:
    http://ruport.infogami.com/blog/ruport_presentation

  • Dudley and I are working on a branch to redesign parts of Ruport’s
    formatting system. The hard-core are welcome to come help hack and
    test.

  • This is a major release. API breakage is likely minimal, but is
    definitely something to watch out for.

== What’s New in this Release? ==

Since we’ve been hacking on this for over a month, theres a lot. The
best way to show off some of the new stuff might be by example, so
I’ve inlined some code into the summary of new features that was in
Dinko’s latest Ruport News article.

From Ruport News (http://www.stonecode.org/blog/?cat=14)

* added ERb support inside SQL queries

 query "select * from <%= some_method %>"

* a new LaTeX plugin for the table formatting engine

[[1,2],[3,4]].to_table.to_latex #=> latex table output

* support for summation in data tables

 [[1,2],[3,4]].to_table.sum(1) #=> 6

* new grouping functionality based on the tagging system

table = [[1,2],[3,4],[4,5]].to_table
table.create_tag_group(:first_col_even) { |r| (r[0] % 2).zero? }
table.create_tag_group(:first_col_odd) { |r| r[0] % 2 ).nonzero? }
group = table.group_by_tag

group.first_col_even.to_a == [ table[2] ] #=> true
group.first_col_odd.to_a   == [ table[0],table[1] ] #=> true

* very large performance enhancements in HTML and text rendering

 These are orders of magnitude faster, though I'm not sure exactly 

how much.
Some things that used to take 30+ mins now take 8 seconds. :slight_smile:

* better integration with FasterCSV

load_csv("foo.csv", :csv_options => { :col_sep => "\t" })
# the :csv_options just get passed along to FasterCSV.

* some simple interfaces for graphs and data tables

 render_graph do |g|
  g.data   = @data
  g.width  = 700
  g.height = 500
  g.title  = "A Simple Line Graph"
  g.style  = :line
end

* syntactic sugar (shortcuts) for common tasks

 # (in report)

 my_table = table(%w[a b c]) do |t|
      #build up table object here...
 end

* support for rerunning reports on timeouts and errors

SomeReport.run(:tries => 3, :timeout => 10) { |r|
    #...
}

There is actually more stuff in this release than what was mentioned
above, but that should get you started :slight_smile:

us though. :wink:

== Acknowledgements ==

Mathijs Mohlmann provided the speed boosts to TextPlugin and
HTMLPlugin. This was an essential fix to Ruport that is much
appreciated. The support
for retrying reports comes through a vendored and slightly tweaked
version of Daniel B.'s attempt.rb, so thanks to Daniel too!

Thank you to NYC.rb for letting me interrupt their hackfest with an
ill-prepared preliminary version of my RubyConf talk, the feedback you
provided was very helpful in making my talk better for RubyConf.
