#Naming Conventions

Both Lua and Objective-C portions of an extension/plugin should contain in-line documention of all of the functions they expose to users of the extension/plugin.

The format for docstrings should follow the standard described below.

#Documentation Rules

Any comment that starts with --- or /// is a doc-string (i.e. 3 comment-characters in a row)
Doc-strings continue on until a non-docstring line
Doc-strings for modules contain === my.modulename ===, then any number of lines describing it
Doc-strings for items (functions, variables, etc.) go like this:
1. The first line starts with my.modulename.item or my.modulename:item -- this is the item name
2. Any non-alphanumeric character ends the item name and is ignored, i.e. parentheses or spaces:
  1. my.modulename:foo()
  2. my.modulename:foo(bar) -> string
  3. my.modulename.foo(bar, fn(int) -> int)
  4. my.modulename.foo = {}
3. The second line is a single capitalized word, like "Variable" or "Function" or "Method" or "Constant" or "Field"
4. The remaining lines describe the item
Any comment that starts with 4 comment-characters is ignored
Only files ending in .lua or .m are scanned

#Constants

--- cp.foo.someConstant
--- Constant
--- This defines the value of a thing

#Variables

--- cp.foo.someVariable
--- Variable
--- This lets you influence the behaviour of this extension

#Fields

--- foo.bar.field <boolean>
--- Variable
--- This is a one-line description of the field

For example:

--- plugins.finalcutpro.os.touchbar.supported <cp.prop: boolean; read-only>
--- Field
--- Returns `true` if the plugin is supported on this OS.

#Functions

Note that a function is any API function provided by an extension, which doesn't relate to an object created by the extension.

The Parameters and Returns sections should always be present. If there is nothing to describe there, simply list * None. The Notes section is optional and should only be present if there are useful notes.

--- cp.foo.someFunction(bar[, baz]) -> string or nil
--- Function
--- This is a one-line description of the function
---
--- Parameters:
---  * bar - A value for doing something
---  * baz - Some optional other value. Defaults to 'abc'
---
--- Returns:
---  * A string with some important result, or nil if an error occurred
---
--- Notes:
---  * An important first note
---  * Another important note

#Methods

Note that a method is any function provided by an extension which relates to an object created by that extension. They are still technically functions, but the signature is differentiated by the presence of a :

--- cp.foo:someMethod() -> bool
--- Method
--- This is a one-line description of the method
---
--- Parameters:
---  * None
---
--- Returns:
---  * Boolean indicating whether the operation succeeded.

#Example Plugin

Here is an example of how plugins should be structured:

--- === plugins.core.example ===
---
--- An example plugin.

--------------------------------------------------------------------------------
--
-- EXTENSIONS:
--
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
-- CommandPost Extensions:
--------------------------------------------------------------------------------
local config			= require("cp.config")
local dialog			= require("cp.dialog")

--------------------------------------------------------------------------------
--
-- CONSTANTS:
--
--------------------------------------------------------------------------------
local MESSAGE			= "The CommandPost Version is: "

--------------------------------------------------------------------------------
--
-- THE MODULE:
--
--------------------------------------------------------------------------------
local mod = {}

--- plugins.core.example.displayVersion() -> nil
--- Function
--- Displays a Dialog Box that displays the CommandPost Version.
---
--- Parameters:
---  * None
---
--- Returns:
---  * None
function mod.displayVersion()
	dialog.displayMessage(MESSAGE .. config.appVersion)
end

--------------------------------------------------------------------------------

-- THE PLUGIN:
--
--------------------------------------------------------------------------------
local plugin = {
	id				= "core.example",
	group			= "core",
	dependencies	= {
		["core.menu.bottom"] = "bottom",
	}
}

--------------------------------------------------------------------------------
-- INITIALISE PLUGIN:
--------------------------------------------------------------------------------
function plugin.init(deps)
	deps.bottom:addSeparator(9999999999):addItem(99999999999, function()
		return { title = "Example Menu Item",	fn = mod.displayVersion }
	end)

	return mod
end

return plugin
