Comments/Ratings for a Single Item

Hi Charles

I've read parts of the Game Courier documentation (much of which is
applicable to the Diagram Designer, from where the documentation can also
be accessed). The part that's devoted to FEN notation, I seem to recall,
mentions handling piece images that use multiple letters to be represented
in the FEN string. For a single piece that uses multiple letters, e.g. for
a (White) "Rocket" it could be represented in FEN in a piece set by RK;
simply use {RK} instead of entering a single letter (if you actually could)
in the FEN string for the chosen piece type. Hopefully an editor will help
if I'm not clear on this.

The short answer is "use brackets" {...}, as Kevin correctly points out. See the third paragraph of this section of the Developer guide.

I didn't see that in the User guide; perhaps Fergus should add it there too?

They're braces, not brackets. To include longer piece names, surround them
with braces.

Fwiw, one thing that's happened is when I've misspelled the name for the
image of a piece within the parentheses (aka braces), nothing will appear
in the diagram for where the piece image should have been. This can also
happen if one forgets one of the pair of the parentheses, or, say, uses one
too many of them.

I would guess that the underscore in their names is the problem?

> I noticed at the same time, that upper case gives black pieces and lower
case white ones, even thouugh the image list gives the more usual reverse.

That's most unusual. When I switched to the regular Alfaerie set, this
didn't happen, and when I used "Alfaerie: Many" on Game Courier, this
didn't happen. I replaced some pieces in the setup with alternates, and I
found that they changed color (as opposed to the pieces rotating position).
When I added some irregularly colored pieces, they disappeared. Reversing
the cases of the letters in their labels did not get them to reappear. So
it doesn't appear to be a simple matter of switching the cases. In case it
was converting everything in a label to one case, I made one lower case
label mixed case, and it disappeared. This is a mystery so far. I'll have
to look at the code and do some debugging.

This is now fixed. The "Alfaerie: Many" set wrote the $flipped array
itself, but drawdiagram.php reset the $flipped array before calculating it.
Stopping it from doing that fixed it.

One of my submission diagrams was affected, as I had previously taken into
account the (former) problem with that particular piece set. After the fix
by Fergus, today I simply switched the Upper & lower case letters I used to
represent the White & Black pieces, in my Diagram Designer generated
diagram.

It would seem anyone else who may have used that particular piece set
should check their diagrams as well.

You can use empty strings for your rank and file labels. Just put nothing
between two spaces, and that counts as an empty string.

That may have something to do with 0 being an empty value. I'll look into
it later.

As you can see, it is now fixed. In the appropriate places, I replaced the
empty() function with a test of identity with the null string (=== ""),
which keeps it from returning a false positive for 0.
