invoking ConTeXt from .bat file in Win7

invoking ConTeXt from .bat file in Win7

[Pablo Rodriguez]

Dear list,

I have the following sample:

  \mainlanguage[es]
  \setupbodyfont[dejavu]
  \starttext

  %~ \startmode[*last]
    \startluacode
    io.write("¿Cuál es el mensaje? ")
    document.message = io.read()
    \stopluacode
  %~ \stopmode

  El mensaje es: \cldcontext{document.message}
  \stoptext

I have two questions about it.

How can I invoke an extra run (as mentioned at
http://www.pragma-ade.com/general/manuals/mmodes.pdf#search=last) to be
able to use the *last mode in the code above?

The other question is that the sample above works fine in Linux. I guess
macOS would be also fine. But in Windows (Win7 in my case), I get
garbage for "¿". "chcp 65001" in the .bat file doesn’t make any
difference. How can I get non-ASCII chars displayed right? (Echoing
UTF-8 characters in the same batch file works perfectly right.)

Many thanks for your help,

Pablo

Partially replying to myself.

Adding a space at the beginning of io.write, displays the space and the
UTF-8 sequence (given "chcp 65001") right.

This isn’t the perfect solution, but it works for me.

I’d really appreciate to know how to request an extra pass in ConTeXt.

Many thanks for your help,

Pablo

As the manual says, "This mode is set if the last run in a session is taking place. Normally this is not known in advance, unless one has asked for an additional imposition pass."

Why do you want to use the last mode for this? The new information can lead to an extra line-break or extra page-break, which might then need an extra run to resolve correctly. So, it might be better to ask the information in the first run and save it in the tuc file using the two pass mechanism:

Many thanks for your reply, Aditya.

Your approach is really interesting, but I don’t know how to mix it with
the first run mode.

  \startmode[*first]
  \startluacode
  io.write("\n\n Document URL?    ")
  document.url_address = io.read()
  \stopluacode

  \definedataset[document_data]
  \setdataset[document_data]
      [url=\cldcontext{document.url_address}]
  \stopmode

  \starttext
  \startTEXpage[offset=1em]
  \datasetvariable{document_data}{1}{url}
  \stopTEXpage
  \stoptext

How could I make this sample or a similar approach work?

What I need it to avoid entering the same address more than once.

Many thanks for your help,

Pablo
