# Markdown to Evernote, RubyCocoa edition

# Adapted from Martin Kopichke's "Markdown to Evernote" service
#   https://gist.github.com/kopischke/1009149
# Which was adapted from Brett Terpstra’s original

# Changes:
# - RubyCocoa instead of shelling out to osascript
# - Separate metadata processing loop
# - Uses capturing regexes instead of manually substrings
# - Read/write contents in one call instead of line by line
# - Do not remove 1st level headers, just use first one as title
#   (Still no setext header processing though)

# 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'
MARKDOWN = '/usr/local/bin/multimarkdown'
Process.exit unless File.executable?(MARKDOWN) 

# Smart typography (aka SmartyPants) switch
SMARTY = false
# – Smart typography processing via MARKDOWN extension
#   enable with '--smart' for PEG Markdown, disable using '--nosmart' in upcoming MMD version 3
SMARTY_EXT_ON  = '--smart'
SMARTY_EXT_OFF = '--nosmart'
# – Separate smart typography processor (i.e. SmartyPants.pl)
#   set to path to SmartyPants.pl (for classic Markdown and MMD pre-version 3, usually same dir as (Multi)MarkDown.pl)
#   set to '' to use SMARTY_EXT instead
SMARTY_PATH = ''
if SMARTY && !SMARTY_PATH.empty? then Process.exit unless File.executable?(SMARTY_PATH) end

Nice script. I've updated the Markdown2Evernote service to include wiki features: http://hackademic.postach.io/post/wikify-the-markdown2evernote-service-pt-2
