Jacqueline,
Works a treat - thanks!
Two things...
1.
I think it would be neater to have all the calculating of user input
in a function somewhere else - in another card, not in the text field
being edited.
(There may be other text fields requiring slightly different joining
calculations).
I tried to identify ONLY lower case letters in the edited text field
because only those need to join.
But Rev treats "a" just like "A" and "b" just like "B" etc.
case pChar "a" returns CAPS too.
[a-z]" failed.
set the HTML failed.
2. Having filtered out all but the lower case, how can I call on a
function thats
somewhere else (from the text field). Should pChar be global?
function joinChar pChar
switch
case pChar is "a" or pChar is "b" return "~"
-- don't do the case thing,
-- go to a function and match pChar to
-- a list of Input and Output values for replacement
-- just replace a with z for now
break
end switch
end joinChar
Rev. docs state...
Unicode characters whose numeric value is greater than 255 are
encoded as "bignum" entities, with a leading ampersand and trailing
semicolon.
For example, the Japanese character whose numeric value is 12387 is
encoded as "っ".
So I guess that's the way to label the characters of pChar that require
joining?
Also labeled that way in the Input and Output lists for replacement?
Thanks,
Adrian

Well, now that you've explained more about it, I think you actually do
have to use this.
It looks like you want to add intermediate characters between the ones
the user types, except at the beginning of words. You use a space as
the word delimiter in your example, but I think you'd have to handle
line beginnings too. For simplicity, let's just check for spaces and
carriage returns.
In a field, you'd put a script something like this:
on keydown pkey
put the selectedChunk into tChunk
put word 2 of tChunk - 1 into tPrevCharNum -- a number
put char tPrevCharNum of me into tPrevChar -- this is a character
if tPrevChar <> space and tPrevChar <> cr and tPrevCharNum <> 0 then
-- not a word start
put joinChar(tPrevChar) into tKeys -- calls a function
end if
put pkey after tKeys -- adds the user-typed entry to tKeys variable
do "put tKeys into" && tChunk
end keydown
function joinChar pChar
return "~"
end joinChar
This catches keystrokes, calculates the previous character position,
and checks that character to make sure it isn't the first character in
the field, a space, or a carriage return. If the criteria are met, it
calls a function that returns the join character. In my example,
that's just a tilde. You'd have to write the guts of the function,
which you would base on the value of the parameter "pChar" which is
passed to the function. The tilde is inserted into a variable, and
then user's keystroke is added to it. The two characters are then
placed into the field using the "do" construct, which is necessary
here in order to evaluate the variable "tChunk" when using it in a
command. (Don't ask.)
That said, when you start using unicode, some of this will break. The
text chunking capabilities in Rev are one of its strongest points, but
they break down somewhat when using unicode. I'm a bit weak in that
area myself, so hopefully someone here can join in and suggest how to
alter the above to account for the additional bytes that unicode
requires. I think you have to add/subtract 2 rather than 1 for all the
calculations, but I haven't tried it.
No offers yet!
Maybe this will at least get you started on how to calculate text
chunks and how to call a function.
