I installed beta-k then m on Linuxmint 64b. 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.
