Import to Day One Journal app from MacJournal Export

macjournal_import.rb

require "open3"

def readfile(file)

	f = File.open(file)
	lines = f.readlines("\n\n\n\n")
	lines.each do |line|
		fields = line.scan(/\s+Date:\s([^\n]+)$\s+Topic:\s([^\n]+)\n(.*)/m)

		date = fields[0][0].strip
		topic = fields[0][1].strip
		text = topic + "\n" + fields[0][2].strip

		puts date
		puts text
		puts "-------------------------------------------------------------"

		Open3.popen3("/Applications/Day One.app/Contents/MacOS/dayone", "-d=\"#{date}\"", "new") do |stdin, stdout, stderr|
			stdin.write(text)
			stdin.close_write
			puts stdout.read
		end

		puts "-------------------------------------------------------------"
	end
end

readfile(ARGV[0])

Thanks for putting this up. The built-in import of MacJournal files dates the entries by creation date, rather than the MacJournal internal date. This gist addresses this, which is nice. However, with the newest version of Day One (1.10.2) the executable you refer to in line 18 does not work. I changed this line to:

Open3.popen3("/usr/local/bin/dayone", "-d=\"#{date}\"", "new") do |stdin, stdout, stderr|

And this appears to solve it.

I've updated @Tam-Lin's script for Day One 2.x. Instructions here.
