Imagine in my right hand I hold a snowball, and off to my left is an
actuarial expert with a very powerful calculator that will determine
the odds of it reaching the target of multi-line and C-style code in
the xTalk IDE. I hurl the snowball, the LED display flickers and the
answer is 7734.
Oh wait, it is the old calculator trick of showing the answer upside
down.
Could not resist the joke that made the rounds in the late 1960's when
I was in college.
Anyway, the archives have the discussion of the anomaly of being able
to set a variable using an equal sign instead of 'put'.
I think this only occurs when declaring a local or constant with a
value.
To me the origins are uncertain.
Consider that IREV allows the following 3-line script to work by
reading each line literally...
<html>
It is <b>traditional</b> to say "Happy New Year" at this time of year,
& why
</html>
The real power of the web servers is in javascript, jquery, and php...
so now where do we stop on the slippery slope of editing features that
appeal to web programmers?
As you can tell, I am fine with Rev editor conventions since I use the
chunking tools to build the many constructs I need for web server
programming.
As Trevor did many years ago, someone may build a lib stack that does
the same thing for HTML as he did for SQL.
Maybe the team is working on this already.
Happy New Year

I use single quote - but run into some problems so got lazy and
replaced
then at the end with "replace "'" with quote. Not sure what
situations cause
the problems - is it OK to use single quotes in Rev htmlText? Not
sure. But
thanks for the tip
NB - I do think that RunRev should add syntax to the language to
make html
quoting very easy to use for both iRev scripts We need an elegant
solution
to quoting html - other languages are easier to use and read with
regard to
html quoting! using our own custom functions does not make read/
writeability
that much easier, and makes it harder to share scripts.
My personal choice would be to have an in-script syntax for putting
raw text
into a variable. The idea would be that you could type the text
inside some
sort of markup, in a way in which you could write anything, and then
assign
it to a variable. That way you could just copy html or whatever and
paste it
into the script editor - easy and readable.
While you can do this with custom properties - and the IDE could be
changed
to make it easier to relate values in custom properties to the
scripts by
showing both in the same window - I'd prefer the ability to do this
all in a
script. This is also important for iRev server side scripts, where
custom
properties are less easy to use.
My suggestion is to extend the syntax for local variables and
constants.
Currently we have:
local someHtml = "<b> hello world </>"
How about something like:
local someHtml = {
<b> hello world </>
}
This would then allow doing things like:
local someHtml = {
It is <b>traditional</> to say "Happy New Year" at this time of
year, & why
not?
You could 'single quote' or "double quote" etc
}
Alternatives could be to use quotes as they are (but allow a special
exception for multiple lines):
local someHtml = "
<b> hello world </>
"
or to use C style quotes:
local someHtml = /*
<b> hello world </>
*/
If you like this suggestion maybe vote for it / improve it here -

NB - at the same time perhaps as implementing this RunRev could take
the
opportunity to enhance local/constant functionality by allowing a
script to
assign values to locals (and constants?) as the value of an
expression:
local someHtml = the htmltext of fld 1
local someValue = fetchSomething("new")
