Task Parameters

Parameter	Syntax Pattern	Additional Info
Title	Implicit Form: add <phrase><SYMBOL>	Form A and B are used for MODIFY operations
	Form A: =<word>	E.g modify Book ={Book of Thrones}
	Form B: ={<phrase>}
Location	Form A: @<word>	Typical use: Form A unless location is made up of more than one word.
	Form B: @{<phrase>}	E.g @{National University of Singapore}
Deadline	Form A: -{<time>}	For deadline tasks
	Form B: -<word>	Form B to support aliasing of words
	Implicit: by <time>	E.g -{tmr 3pm}
Time Frame (to and from)	~{<time>} -{<time>}	For timed tasks which have a start and end time.
	Implicit: from ~{} to -{}	E.g ~{tmr 2pm} -{tmr 3pm}
Category (hashtag)	Form A: #<word>	Integrate ‘twitter mode’ into basic mode.
	Form B: #{<word>}	Typical use: Form A but to also support Form B for consistency with other syntax
		E.g add ={Buy tao suan} -{tmr 3pm} #ts
		Should support multiple categories
Description	Form A: +<word>	2 forms to be consistent with all other syntax
	Form B: +{<phrase>}

	Form B: !{<time>}
Priority	Form A: %{<zeroToTen>}	Priority levels: 0-10
	Form B: %<zeroToTen>	Where 0 is lowest (green) and
		10 is highest (red for urgency)

BNF Definitions

<phrase>:= <word> | <word><space><phrase> | <phrase><space><word> <zeroToTen> := 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 <SYMBOL> to be further discussed

We will implement the explicit form for all the parameters, which will always be in the form <SYMBOL>{<phrase>}

The default parameter symbols will be:

• Category: #
• Deadline: -
• Description: +
• Location: @
• Priority: %
• Reminder: !
• Title: =

I think we can implement the explicit form for now. For the implicit forms, @rodsonchue can create 2 new issues(tasks) one for Explicit parameters(support for no {}) and another for Implicit parameters. The implicit will be available only for Title, Deadline and Timeframe. Also @rodsonchue clean up the description above to include only the descriptions for this task only.
