simple example fails

[Roger Mason]

Hello,

I'm playinng with a simple example:

fold::amrita {
set str = filename
set str .= .tex
fold::print {
fold> file = $str
fold> print fold::context []
fold::context { do something interesting
\starttext
Hello, world!
fold::context { and so on
\stoptext
}
}
}
}

but it fails with:

Error at line 19 of file context2.amrita:
missing '}' from line 1!

Line 19 is:


error near:
end of line

I have verified that the fold:: and brackets line up (although it may
not appear so in e-mail).

Thanks,
Roger

I cut-n-pasted your script and it works at this end.
Do you have any tabs in your script? If so, that
will mess up the fold nesting. But you can send it
as an attachment, so that I can check it. You can also
run the script with the -maiit option which will produce
something you can e-mail.

p.s. Did you write the script using amrgi? If so,
the brackets are guaranteed to line up.

Yes, that was the problem. It works here too now.

OK. The output includes what looks like garbage:

AmritaMailit::context2.amrita {
origin {
Amrita v3.05 R25-04-2010

I could not find documentation on -mailit.

No, I used emacs. I have been working on an amrita-mode. There is
nothing wrong with origami: it is just that my fingers are hard-wired to
emacs keybindings. My amrita-mode is crude at the moment, but can be
used for simple scripts. I just fixed it to use spaces instead of
tabs+spaces for indenting.

A discussion of their operation and purpose is give in VKI lecture #1.

Unless your mode includes folding then you will not benefit from
fold::print's construction, or at least not in the way it was intended.
