Automating todo tasks lists reports

Here's the geek automation of the week, its for helping creating reports from my TODO tasks list when using the amazing emacs org-mode(see here whats org-mode all about).

(simplified) Work Flow

1. I get a request, add it into my todo list queue, marking it as a TODO item.
2. Work, work, work, guided by the todo listed tasks, balancing priority and effort and (..add your own reason here..).
3. When finished, mark an item DONE.
4. Generate a report every week with the done tasks.

Generating the Report

(I use this setup on Mac, with some adaptations should also on Linux and Windows)

Every week i then generate a report of the DONE Tasks, by running:

# file: get-work-done.sh 
# run: sh get-work-done.sh

# Uses emacs to extract the DONE items from work.org, generating a work-done.csv
/Applications/Aquamacs.app/Contents/MacOS/Aquamacs -batch -l ~/.emacs -eval '(org-batch-agenda-csv "+TODO=\"DONE\"" org-agenda-files (quote ("/.../work.org")))' > work-done.csv

# Applies desired report formatting to the exported work-done.csv, generating work.csv
ruby format-report.rb work-done.csv

# Clean up the originally exported file
rm work-done.csv

# Opens the final file in the default .csv handler, typically Excel.
open work.csv

(see the comments "#" to understand what it does in each step)

Then I use the format-report.rb bellow to apply formatting to the report, for example: add my own header, add/remove columns, Dates, change names, calculate values, etc, etc... see example:

# file: format-report.rb

flines = File.open(ARGV[0]).readlines

column_map = { 
  "friendly_name_i_use1"  => "required_final_report_name1", 
  "friendly_name_i_use2"  => "required_final_report_name2",  
  "friendly_name_i_use3"  => "required_final_report_name3"
}

File.open( "work.csv","w+") do |fl|  
  fl.puts "header1,header2,header3,header4"
  flines.each do |l|
    a = l.split(",")

    # Time, mapping-defined-in-column_map, original-column-2, original-column-3
    fl.puts Time.now.strftime("%m/%d/%Y") + "," + (column_map[a[1]] || a[1]) + "," + a[2] "," + a[3]
  end
end

And voila, i run this and an excel sheet opens up with the report of the week.
