Hi,
I have had a look at the Tcl examples to get rid of the locally
defined values - we now have a namespace containing the definitions
of "symbols" such as PL_POSITION_LEFT and FACETED. I noticed that
quite a lot of the examples use "bare" expressions, like:
$w cmd plarc 0.0 0.0 [expr 0.1 * $i] [expr 0.1 * $i] 0.0 360.0
This is not the idiomatic way in Tcl: the advice is to always brace
your expressions, so that the above becomes:
$w cmd plarc 0.0 0.0 [expr {0.1 * $i}] [expr {0.1 * $i}] 0.0 360.0
The reason is that a braced expression needs to be parsed only once.
My intention is to go through these examples and change the
unbraced expressions to braced expressions AND replace the locally
defined constants by the ones in the PLPLOT namespace that we now have.
But should I commit these changes separately? Or does that not matter?
Regards,
Arjen
