Well... I tried using chrome (which is heavily integrated with google search). In the address bar, I typed: code.jsoftware.com and when I hit space, it brought up a j wiki search. In other words, when I searched google for: code.jsoftware.com rand11, it brought up http://code.jsoftware.com/mediaw

Re: [Jprogramming] Call for Wiki work: standard library

Ok, note however that that Addons page that I modified is a landing page for the Addons top nav. If you go back to the page I modified you can see that Addons is bolded (and black) in that blue JAL bar. So now I need to think about that a little. Meanwhile, here's the system libs: require'general

Re: [Jprogramming] Parity patterns

Well... if you really wanted to go overboard on rephrasings, you could take that a bit further and do something like this: grow=: , _2&{ ~: 3 ~:/\ 0,{:,0: paritypattern=: 1 }. [ grow@:]^:([-1:) 0 ,: ] Though, of course, getting rid of meaningful names is not always a good thing. Anyway

Bravo!  I have moved the page to http://code.jsoftware.com/wiki/Vocabulary/Libraries which is a place where a new user is more likely to stumble into it, I think. I see you have the Addons; what about the standard libraries like strings, regex, debug, etc.?  They need to be documented in the

Re: [Jprogramming] Call for Wiki work: standard library

The Addons page is nice. However, my test, which consistes of searching for "rand11" in the main Jsoftware search bar, still doesn't find any substantial references in the wiki pages, even though the key rand11 references are mentioned several times at: http://code.jsoftware.com/wiki/Addons/stats/b

I am not sure that if there's a better approach, though obviously we could rephrase your approach slightly. For example: nextrow=: [ ~: 3 ~:/\ 0,],0: grow=: , _2&{ nextrow {: paritypattern=: 1 }. [ grow@:]^:([-1:) 0 ,: ] I hope this helps... -- Raul On Tue, Oct 31, 2017 at 5:05 PM,

What you are talking about is what I was looking for as a starting point.  It would give a list of addons, and within each addon, a list of scripts. Then, for each script someone would need to extract the entry points and add a description of what the entry point does.  Maybe this could be au

Yes, the eventual goal being to have a line in the new page for each entry point in the libraries. We should back up to what I want for the user.  I want someone to be able to wonder, "what does J do for me for reading JSON files?" or "how does J read images?" or "how do I create a CSV file?"

Thanks. One change I would make from the old Addons page is to not list the addons separately for each release, i.e. no need for JAL/805, JAL/804 etc. Instead, each addon page can indicate its target platform, and pages for obsolete addons can be moved elsewhere. On Tue, Oct 31, 2017 at 7:43 AM, H
