Query language

[harshad1]

Is there a query language / syntax in common use with todo.txt. Something like the todoist filter language?

grep?

Lol. I should have been more specific.

I am thinking of implementing a todo.txt query system in Markor. This would be something a user could enter in the app and would be more todo-syntax specific than a general purpose filtering system like grep (or regex).

For example (*A | *B) & +work would be +work tasks with priority A or B.

I could come up with something myself, but I'd rather use an existing syntax / format, if it is in use in other clients.

Any opinions on this:

{
    "note": "Todo text filter in json format",
    "and": [
        "project": "work",
        "or" : [
            "context": "meeting",
            "context": "george"
        ],
        "not" : {
            "or": [
                "priority": "C",
                "priority": "D",
                "priority": "E"
            ]
        },
        "or": [
            "due": "today",
            "due": "overdue"
        ],
        "done": false
    ]
}
