/* 
 Ver 0.9.0 Send Draft.app draft to Obsidian with YAML front matter. 2021-08-08
 Ver 0.9.1 Correct a copy/paste error causing runtime exception. 2021-08-09
 Ver 0.9.2 Switch YAML date to draft creation date. Clarify comments 2021-08-12
 Ver 1.0.0 Restructure to turn all YAML, except the tags, user configurable
			text. Makes configuration of custom YAML possible. 2021-08-18
 Ver 1.0.1 Add "inbox" folder option and createSilently option. 2021-08-21 
 
 From a direction pointed to in Ulysses sheet w/ tags action.
 Thanks to Olivier Spinnler (@OlivierPS) and others. 

 Metadata lines and tags are formatted as YAML front matter then appended 
 with the Draft text. The combined text is then sent as a new note to your
 Obsidian vault. The text of the Draft remains unaltered by this code.
 
 
 >>>>>>>> NOTE: Configurable items to set below <<<<<<<<
 
 MANDATORY: Modify vaultName with the name of your target vault.
 This action won't work without a correct name for an existing vault.

const vaultName 		= "your-vault-name-here";

 /***NEW*** The transfered note will be located either where Obsidian settings 
	say new files shoud go, OR, in a "inbox" folder you configure below.

 Examples:
 
 	inFolder = "" will rely on the Obsidian settings for where to put the file.
 	It should be noted that Obsidian's "Same folder as current file" setting
 	will depend on the currently open Obsidian file. The "current file" context
 	exists even when Obsidian is not running. If a file was open on quit, that
 	is the current file. If no file is/was open, Obsidian will locate the new 
 	file at the top level of the vault as there is no other possible context  
 	for "current file". 
 
 	inFolder = "From-Drafts" will put the note in a "From-Drafts" folder which
	is assumed be in the top level of the vault. If "From-Drafts" does not
 	currently exist, it will be created. 
 
	inFolder = "gathered/Drafts" will place the note in the "Drafts" subfolder
 	of the "gathered" folder. Those folders will be created if they're not
 	already there.
 */
 
const inFolder = "";

/***NEW***  createSilently determines whether the Draft should silently create
   the new Obsidian file in the vault, or, alternatively, should the new file 
   be opened and brought to the front. In either case Obsidian will be made the
   active application.

/*
   Any one of the following headerItems can be changed to suit your needs.
   The label, e.g. "Author", gets combined with its value, e.g. "Mr. Magoo",
   to form a YAML metadata line, e.g., "Author: Mr. Magoo"

   Values do not have to be literals, they can be calculated as shown
   in the default Title or Date lines below. E.G., if you wanted to have
   the default Date item be todays date, use getISOShortDate(new Date)
   For attributes of the draft, see https://scripting.getdrafts.com/classes/draft

	I chose these data as reasonable metadata for a document, ala PDF or 
	Word. Your needs and mileage may vary. I tried to make it easy for those
	uncomfortable with coding to change things to meet their requirements.

   Any or all of the frontmatter lines can be deleted if they're of no 
   value to you. Be sure to leave the lines "let headerItems = [" and "];"

   Conversely, you can add any new lines you need by following the pattern.
