declare person is composite of first-name is text, last-name is text

declare names is array of text

Allow a comma to be followed by a new line, like:

    If it is the afternoon,
        display "Good afternoon, {persons-name}!",
        otherwise display "Good morning, {persons-name}!"

They should not be mixed in with other sentences

Just some basic functionality.

display (counter + 1)

Only variables and arithmetic will work.

Binary builds for windows, mac and linux.

Bento looks really interesting...

Can Bento be used with something like Bash Shell scripts?

What I mean is can Bento call a Bash script
or
Can a Bash script call a Bento program?

Or is that what "a backend" is about?

A backend is program controlled by bento. A backend can be any program (compiled or interpreted) that implements the bento protocol on the port specified on the BENTO_PORT environment variable.

If Bash can be used could you give an example of calling a Bash script and perhaps returning a "value" from the script?

thanks

At the moment it is hard coded to 6.

When a parsing error occurs it should show the line/character.

Still trying to work out what error handling will look like, here is a rough idea:

start:
    declare last-order-date is text

    # one line
    try to fetch last order date into last-order-date, on no-orders set last-order-date to "unknown", on missing-order display error-message, always display "Fetched order date"

    # one line with better spacing
    try to fetch last order date into last-order-date,
        on no-orders set last-order-date to "unknown",
        on missing-order display error-message,
        always display "Fetched order date"

    # multiline
    try
        fetch last order date into last-order-date
        display "Fetched order date"
    catch no-orders, set last-order-date to "unknown"
    catch missing-order do
        display error-message
    end

fetch last order date into dest (dest is text):
    raise error no-orders
    raise error missing-order with the message "Where did it go?"

bento format to format files like go fmt works.

if (foo = 123) and (bar != “baz”), ...

Conditions must be in parenthesis. This means we don’t have to worry about operator precedence and it’s more explicit so it’s much easier to parse and understand.

These are used in decisions and loops for a block of statements.

declare scores as dictionary of text to number

bento run room.bento -- walk into the room

Unless works the same way as if but inverts the condition.

If the grammar of a declare is incorrect it will be treated like a normal sentence, which it shouldn't.

Likewise, no sentence is allowed to be defined with the first word as "declare".

Sometimes we want to discard the value when calling, like:

run system command "echo hi" output into _ status code into echo-result
