Grace is a strongly typed, general-purpose language that was designed to have a somewhat similar syntax to COBOL while having the functionality of Python. Currently, Grace is in extremely early development, having only a small pool of features implemented. Grace is based on tasks, which are snippets of code that are executed based on their head's sequence in id-div.

Syntax

Operators

Grace has a relatively small assortment of operators, most of them being mathematical. Grace has operators for:

• Math (accessed using the math: operator in Grace): +, -, *, /
• Logic (accessed using the logic {} block in Grace): =, <, >

Commands and Blocks

• head {}, for the head data of a program
• id-div {}, for defining task heads.
• task-body {}, for defining the tasks themselves.
• logic {}, for defining logic gates
• else {}, for putting inside logic gates to execute code when the logic gate is not true.
• function {}, for defining functions.
• say: , for outputting text from the standard output
• input: , for inputting text from the standard input.
• prog-name: , for defining the name of the program.
• prog-desc, for defining the description of the program.
• task-head: , for defining the heads of tasks.
• var: , for defining variables
• list: , for defining lists
• array: , for defining arrays
• dict: ,for defining dictionaries.
• math: , for doing math.

Example Code

Basic matrix in Grace:

head {
        prog-name: “Matrix”
        prog-desc: “Matrix demo”
}
id-div {
        task-head: name=”matrix” id=”1”
}
task-body (id=”1”) {
        say: “Basic matrix made of arrays!”
        array: arr1 = ([“1”, “2”, “3”])
        array: arr2 = ([“4”, “5”, “6”])
        array: arr3 = ([“7”, “8”, “9”])
        say: arr1
        say: arr2
        say: arr3
}

Number guessing game:

head {
        prog-name: “Number guessing game”
        prog-desc: “Fun little game!”
}
id-div {
        task-head: name=”game” id=”1”
}
task-body (id=”1”) {
        var: txt = input: “Guess a number”
        logic (log=”if txt = “5””) {
                say: “Well done!”
                else {
                        say: “Whoops! Looks like you guessed the wrong number!”
                }
        }
}

Custom "add" function:

head {
        prog-name: “Functions”
        prog-desc: “Functions demo”
}
id-div {
        task-head: name=”testtask” id=”1”
}
function (name=”add” args=”add1”, “add2”) {
        var: addition = math: add1 + add2
        say: addition
}
task-body (id=1) {
        add: add1=”1” add2=”1”
}
