Re: [tcljava-user] Jacl documentation

[Wei D. <wd...@fn...>]

I am not planning to manipulate them; all I want is to be able to
retrieve them since we wanted to provide a console log that display what
user would see if they run tclsh directly. So if puts commands result
only comes from the STDOUT, I need to a way to get it. Same for the
STDERR, it seems to me that Interp.getResults can provide error message
in the error case, but is it the same message that I would get from
STDERR?

Thanks and Happy Holidays :)

Hi Wei

Please do explain what you intend to do with STDERR and STDOUT, they are
used by the tcl commands to print the results, and I am not sure how you
are planning to manipuate them.

    How ever, if you are planning to capture the results of an
expression evaluation, then Interp.getResult should give you the
result. If you are checking for any exceptions, just catching the
TclException and checking the Interp.getResult should give you the
exception raised. (check the Shell.java for example on using it.)

| I also wanted to know if Interp.GetResults can be the used as STDOUT
or
| STDERR. I have noticed most time that it seems to be the STDOUT or
| STDERR, but it does not give me STDOUT when it comes to commands like
| puts.=20

If you are familiar with java, puts behaves similar to
System.out.println (by default with out a channel) while the
Interp.getResult gives you the value of an expression evaluated. (like
that of a function call in java.)
