`html2sprockets:assets` is a quick way to add 3rd-party js/css to your rails app that is asset pipeline compatible; creates local gem in `vendor/gems` and apply them in your `Gemfile`
require 'fileutils'
namespace :html2sprockets do
desc "Setup env for gem creation"
task :env do
@gemname = ENV.fetch('NAME')
@gemdir = File.join(ENV.fetch('GEMDIR', 'vendor/gems'), @gemname)
@asset_dst_path = File.join(@gemdir, ENV.fetch('DST', 'vendor/assets'))
@asset_src_paths = ENV.fetch('SRC').each_line.collect(&:strip)

So you want to modify the text of a PDF by hand

So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.
