The current code in the wiki for Trajectory runs fine for me on Ubuntu Beta-m,
j4avx2 with 1.0.5 fold.

Gilles,
?? I have modified the Fold script so that it allows messages from
execution of the user's verb to be displayed and debugged.?? Use
Package Manager to update dev/fold - no need for a new beta.
?? I hope that suits better.

My desktop directory is named Bureau, not Desktop. The installer is thus
unable to install shortcuts on Desktop. Minor annoyance. I created a
link to Bureau for next time. May be suggest to do so in install
instructions. I added a few qt5 missing packages.
With the current IDE, to find the syntax of std lib utilities (e.g.
dates, files, strings, text), I have to go through Help, Help, Usr,
Standard Library, ... More importantly I have to KNOW that the std lib
doc is there.
Do you think a newcomer will easily explore to that level? The Library
is a selling point. It should be easy to get to. And IMO the Lib is more
useful to anyone than Foreigns.
Two years ago, I proposed to add a line to the Help Menu pointing to the
std lib doc. IIRC the proposal was accepted, but ... so I reiterate.
Having launched jqt through a terminal, I received the following:
QPaintDevice::metrics: Device has no metric information
Should I worry?
I briefly experimented with Fold after reading the Release Notes. Those
could include a link to https://code.jsoftware.com/wiki/Vocabulary/fcap,
which I found through a web search.
I tried to run the Trajectory example from that page and got a value
error. Where? A visual look at the script revealed a susceptible
culprit: mean. Added require 'stats/base' and it ran.
While trying the Trajectory, I ran the script with the debugger. [The
debugger did not fail, great!] The value error on mean was not obvious.
The stack is given as:
value error
Fold_j_[40] 13!:8]13!:11''[FoldZv_j_=:fzv
trajectory[0] u F: v y
This Trajectory example is a simple case. I suspect that errors in more
complex cases may not be easy to analyze.
??From a notational point of view, the Fold family is a great addition, I
think.
