In the tool package (tools.ypr or ToolSprite.ysp in the BYOB folder) there's a block SENTENCE->LIST that does what you want.

Perhaps I am looking at the wrong list blocks, but it is not obvious how to get the string input to convert to separate list items. In other words, if the input sentence is "My name is John", how do I transform this into a list of 4 items:

1 My
2 name
3 is
4 John

rather than a list of 1 item (with the 4 elements above as sub-items of that item)?

I can think of complicated ways to either get the list to be the way I want -- or to read the sublist in item 1. But is there a simple way to just use SENTENCE->LIST to convert the string into a 4-item list?

Hi knubee,

I just again checked the sentence->list reportert block (it's in the green "Operators" tab), and it transforms an input of "My name is John" to an anonymous list of four items, one word each. You have to open the tools.ypr file in BYOB or import the ToolSprite.ysp file, switch to the green Operators tab, drag out the (round) reporter block named sentence->list [_] and type your sentence into the input field, and double click on the reporter block.

Please let us know if this doesn't work for you.
Thanks!

Ta da! Here's the official BYOB 3.1 release:

Macintosh

Windows installer

Windows files only

just image and changes

A few remaining glitches have been fixed, some localization issues remain, especially with non-Western codepages. Check out Brian's cool animals game!

Thanks, everybody, for the tireless testing, and for all your encouragement.

Enjoy!

If you have 3.0, you should probably download the complete 3.1 package, which includes new help files, projects, localization, and tools.

Onward to 4.0!

Yes, text can be entered directly into the sentence->list block. However, I am trying to grab user input that is (temporarily) stored in the ANSWER block (variable). Thus, the natural thing to do is create <sentence->list [answer]>. So far, so good. The resulting combination of blocks reports the user input in the form of a list of four items.

However, I want to NAME that list so I can then operate on it. Is there a straight-forward way to do this? (If it can be avoided, I would rather not add that list as item 1 of a named list)

Use a variable and set the variable to the (sentence (answer) -> list). smile

Use a variable and set the variable to the (sentence (answer) -> list).

Oh, yes, that gives me a named variable with the list as its value. But there is no block for "variable contains [thing]". Basically, here is what I was hoping to be able to do:

1. capture user input to "answer"
2. convert the sentence in "answer" to a named list
3. test the named list for presence of keywords

Is the only way to do this to assign the input list to a variable -- and then create my own "variable contains [thing]" predicate?

If the value of a variable is a list, you can drag the orange variable blob for that variable onto the list dropdown menu of any of the list blocks, and the block will take that variable's value as the list to operate on.

P.S. For that matter, you can just say

IF < (SENTENCE->LIST (ANSWER)) CONTAINS whatever > ...

without putting the list into a variable or anything.

Ah! The ability to drag blocks onto pull-down menus was the bit I was missing. With that, yes, I see a number of ways of doing what I want.

Thanks for all the help -- and all the good work on BYOB. It is really nice to be able to introduce a wider range of programming concepts and techniques with this version of Scratch!

There's an APPEND block in the tools library for lists. As for scripts, editability is still a little ways in the future, maybe 4.0 or 4.1.
