I turned on support for PDL::IO::Browser, and in spite of what the
perldl notes say, it installed just fine. It is actually pretty
brilliant, neatly laying out the values of a piddle so they can be
examined.
The only problem... it is not quite clear how to navigate. See below
pdl> $foo = byte(sequence 300,200)
pdl> browse $foo
Perldl data browser: type 0, (300,200), type q to quit
0 | 1 | 2 | 3 | 4 | 5
| 6 | 7 | 8 | 9 |
0 0| 1| 2| 3| 4|
5| 6| 7| 8| 9|
1 300| 301| 302| 303| 304|
305| 306| 307| 308| 309|
..
So, what the heck does that "type 0, (300,200), type q to quit" mean?
It is like "the panda eats, shoots, and leaves" instead of "the panda
eats shoots and leaves."
Initially I thought the prompt was asking me to type 0 (ostensibly to
navigate) or type q to quit. Much later did I realize that the first
type was a noun and the second type was a verb.
Ok, I did a little bit of browsing, and then tried to quit. Well, the
browser just kept on popping back up. Eventually, I had to kill the
pdl process to get out of that loop.
It is a neat technology, builds without any problem on Mac OS X
10.6.4, and would be very useful if some of the kinks were removed,
and the docs were improved.
