# Adapted from Brett Terpstra’s original “Markdown to Evernote” service (http://brettterpstra.com/a-better-os-x-system-service-for-evernote-notes-with-multimarkdown/)
# Martin Kopischke 2011 – License: Creative Commons Attribution Share-Alike (CC BY-SA) 3.0 Unported (http://creativecommons.org/licenses/by-sa/3.0/)
# Changes: – support for setting the creation date with 'Date:' MMD metadata attribute
# – create only one Evernote note per (Multi)Markdown input passed (instead of one per line)
# – do not choke on shell escape characters (use Tempfile instead of shell pipe for osascript)
# – default to MultiMarkdown 3 executable (instead of MMD 2 Perl script)
# – make smart typography processing optional (set SMARTY to 'false' to bypass processing;
# note smart typography cannot be disabled in MMD 3.0 and 3.0.1
# – handle both smart typography processing scripts (ie. SmartyPants.pl)
# and (Multi)Markdown processor extensions (i.e. '--smart' and MMD's upcoming '--nosmart')
# – handle both command line switches to (Multi)Markdown processor and separate smart typography processors
# – restrict parsing for metadata (note title, tags, target notebook) to the metadata block as per MMD spec
# note atx style 1st level headings will be parsed anywhere, as they terminate the metadata block anyway
# – specify note title in metadata block MMD style, using 'Title: <name>' (not just as 1st level heading)
# – specify target notebook in metadata block either with '= <name>' or MMD style, using 'Notebook: <name>'
# – specify tags in metadata block either with '@ <tag list>' or MMD style, using 'Keywords: <tag list>'
# – correctly parse tag names with punctuation (no commas) and other “special” characters
# – correctly assign multiple tags (instead of quietly failing)
# – correctly parse all flavors of 1st level atx headings (not just those following the hash with a space)
# – use localized date time stamp from AppleScript (instead of US formatted) as fallback note title
# – use Evernote default notebook if none is indicated in input (instead of 'Unfiled')
# – added minimal sanity checks (like make sure Markdown executable actually exists and is executable)
# – runs on Ruby 1.8 and 1.9
# To do: – process settext 1st level headings
# – ignore Markdown 1st level headings when a 'Title:' metadata line is found?
# Markdown executable path
# – edit to match your install location if non-default
# – pre-version 3 MMD script usually is '~/Application Support/MultiMarkDown/bin/MultiMarkDown.pl'
