It's really not philosophy or history I'm looking for. My problems are very RunRev specific. Here are the kinds of things I'm struggling to figure out on my own, that I think a good tutorial could have helped with:
1 - I'm writing a children's online Chinese dictionary, so I want a text field to hold multibyte characters (specifically Chinese and Japanese characters). I'm using Mac OSX, so I can easily activate the input method to enter the characters, but I can't seem to manipulate them in any way. For example, I can't choose a font or size in the Property Inspector, can't get or set the contents using the message box, etc. It turns out that I need to manually (using script or messagebox) set the textFont of the field to something like "Osaka,Japanese" (and you can't have any extra spaces after the comma). That wasn't intuitively obvious.
2 - Ok, now I have double-byte text in a field, and I want to copy it and display it somewhere else. I plan to use characters from the dictionary stack and I want to have a Concentration card game which will let kids practice recognizing Chinese characters. Unlike situations involving plain text, I can't just say "put field 1 into field 2." I have to say something like "put the unicodeText of field 1 into field 2". Oh yeah, and Field 2 had better already have its textFont property set correctly, too, or the results will be gibberish. How would I have known to even look for a "unicodeText" value? I think it took me about an hour to figure out how to use it correctly, even after I found it.
3 - I have a solitaire tile game ported from Hypercard which lets you click on matching tiles to remove them from the pattern-- very standard. Each tile is a button, and when you click on them, the sound that goes with the character is also played. In my original, I hand-drew all the Japanese characters as icons, and set the icons and names of each button with a shuffle script. Now I'd like to set the labels of the tiles instead, to a multibyte value. Well, it's a good thing I wanted to script this, because as I discovered while testing to find a good font and size to use, you can't set the label to a multibyte or Unicode value using the Property Inspector. You also can't just type the Unicode text into a script or the messagebox. You need to put it in a file or field which has had its textFont property set. After searching the documentation, this list, and much trial and error, I found the command I needed:
set the label of button "mu" to the unicodeText of line 1 of card field "testUnicode"
But even that won't work unless one has also remembered to set the textFont of the button itself.
I still haven't found an actual use for uniEncode and uniDecode. I assume I'll find some situation within the next week or so for which I'll need them, but it sure would be nice to know now where I'll use them.
My point is that the existing documentation on this subject resembles an old joke in which a man lost in a hot air balloon tries to get help figuring out where he is from someone in a window who turns out to be a Microsoft tech support engineer, who tells him "you're in a hot air balloon." Absolutely true, but not very helpful. Knowing the syntax of a command does one little good unless one knows which command to use in a given situation, and the docs are woefully low on context.
Then again, that's what a good tutorial should provide.
