List Commands Library for 50g

[pier4r]

I like the about page, it gets better and better. Now it explains also the complement to goferlist. "compact" meaningful notes are always precious.

Side note. I just thought "hey, since I am involved, let's pick all the discussed library/commands from lists ... well aside those shared on the forum that, while neat, takes a bit of time to be collected, now I want just to pick those I remember from memory". The I have already goferlist and I picked LSORT (that is in saturn assembly. I think also HRAST basic is saturn assembly. Is that emulated as well?). There are nice notes in LSORT, but may be overkill for the list of David. Anyway the notes once again confirm that: shared documentation is better.

Quote:5.To Do

- binary integers
- units
- degeneracy check for Quicksort, switch to Heapsort
- v1.0 will be the first version that incorporates all of the above. From then on
it can be used as a true replacement for the built-in SORT.
- ASORT (array sort) using the same subroutines
- CSORT (column sort)
- ORDERBY (multiple keys)
- LUNIQ (remove duplicates)
- make a lib of the above

I'd say ASORT, CSORT, ORDERBY are nice ideas (units too, but that starts to be professional even though CSORT/ORDERBY are really hard already I think).
LUNIQ is already done IIRC.

For CSORT in terms of lists, I'd imagine a list of sublists (with the same length, like exploding a matrix in lists) and ordering by the n-th element of all the lists.

OrderBY would be similar to Csort actually, just one could give multiple elements in terms of priority. Like "order first the sublists by the 3rd element, then if the 3rd element is equal, use the 4th as tiebreak" and so on.


Moreover it is amazing to see that while a new firmware/language for the hp50g gets developed (newRPL and not only those, some months ago there was HRAST basic), the built in language gets expanded with very nice utilities to this day. Really amazing. I wish every collection of devices that were useful and popular would have the same dedication from the community.

But this was discussed also here: http://www.hpmuseum.org/forum/thread-8204.html
