Re: [Bug-apl] Calling Value::print() with different ⎕PW

[Juergen Sauermann]

Hi Elias,

yes, sorry. Forgot to mention that the APL values used in the constructor of UCS_string
must have rank ≤ 1 while do_CR() might produce matrices for some left arguments of ⎕CR.

Do you have any idea?

Hi Elias,

the operator<<(ostream & out, const Value & v) calls v.print(out) which then
does the line break at ⎕PW. The cr_formatted below is probably OK but printing
it introduces line wrapping. You could have used UCS_string(*cr_formatted) instead
of *cr_formatted to avoid that.

I tried to specify a different PW like the below, but the with is still limited to something close to 80:

        const PrintContext pctx( PST_NONE, Workspace::get_PP(), 1000 );

        Value_P cr_formatted = Quad_CR::do_CR( cr_level, *value, pctx );

        out << *cr_formatted;

What did I do wrong?

Elias
