Re: Repeat syntax addition
(Going back to HyperCard?) the concepts used to be containers and sources of value - where the latter can be a literal, a function call, an expression... I always thought that containers were a subset of sources of value, defined as the items where you could set the value as well as get it; but looking at the current LiveCode user guide I see that these are used as exclusive sets, where the key distinction is not whether the item can be both evaluated and changed, but whether it can be changed using put. So a field is a container, just as a variable is; but a property is a source of value because you need to use the set syntax to change it, so it's grouped with a constant literal or an expression, which is read-only. This seems wrong to me, and I don't know whether it marks a subtle change. At any rate, the desirable change in the dictionary would be to replace container with container or source of value - better not to introduce a new term altogether!

Re: Repeat syntax addition
I'm really liking this feature. I just used it in a series of nested repeat statements that traverse their way through an array with 5 levels of keys by writing a function for each level of key. Makes the code so much more readable.

Re: Repeat syntax addition
Peter Haworth wrote Wouldn't it be nice if you could: repeat for each line rLine in tLines where rLine begins with xyz . end repeat It would be even nicer if we could have the more general form repeat for each line rLine in tLines [/condition/] [/transformation/] ... end repeat where [condition] is an optional condition that returns a boolean, and [transformation] operates on the line to transform it. Thus, it could be useful as a filter, universal transformer, or conditional transformer.

Re: Repeat syntax addition
Nic Ralph. Useful where you don;t want to incur the overhead of repeat with but still need a counter.

Re: Repeat syntax addition
As long as you wrap your function in parens so that it forces evaluation first, then yeah. Have the function do your filter, and then return the filtered data. (not positive you even need the extra parens, but its a habit for me in cases like this.) repeat for each doesn't really care where the list comes from, so an inline function call is just fine.

Re: Repeat syntax addition
Wow, didn't know that, thanks. The dictionary doesn't give any clue that's possible, just uses container as what follows in. Does that mean that anywhere the dictionary uses the word container, it can be a function call?

Most likely yeah. I wouldn't swear 100% (I like to TRY first lol) but it SHOULD work. On Sun, Apr 5, 2015 at 2:40 PM, Peter Haworth p...@lcsql.com wrote: Wow, didn't know that, thanks.
