Talk:Joy (programming language)

message: I know there's already a comparison for square, but that's very simple, and, being an outsider, I can definitely say that the Quicksort algorithm shown is complete and utter Greek as far as I can tell. Perhaps someone could put in a side-by-side comparison with a more familiar language (such as C or Java), in such a way as to be able to see and understand what each part of the function means. --Dlevenstein 12:11, 30 May 2007 (UTC)

message: "the meaning function is a homomorphism from the syntactic monoid onto the semantic monoid"
What does this mean? Lmatt 13:28, 5 June 2007 (UTC)
replies: text: Appending words to the program composes the program with those new functions.  But that's uninteresting---and true for most languages.  Adding well-formed subprograms to the end of programs in C, Forth, most Lisps, Python, etc. adds new functions to the program.  The monoid structure of the program isn't very interesting.  It's the branching and looping structure inside the program that's interesting.  —Preceding unsigned comment added by 80.67.64.10 (talk) 12:41, 9 March 2009 (UTC)

text: Mathematical purity, that is to call a programming "pure", means that application of functions are free from side-effects. They don't change any state except the ones within their scope. A typical example of non-pure function is random number seeding and generation.  — Preceding unsigned comment added by 60.249.196.111 (talk) 02:08, 14 May 2014 (UTC)

message: Manfred von Thun, inventor of Joy, has passed away some time ago, and apparently his "Official Joy Programming Language Website" at La Trobe University is no longer online. Kevin Albrecht's mirror still appears to work, however. —Tobias Bergemann (talk) 14:55, 6 January 2013 (UTC)
thread_title:  Official Joy Programming Language Website (La Trobe University) 

message: Apart from the language documented here, there is another programming language named Joy that I am somewhat familiar with. It is a dialect of Occam, which was used for description of self-timed silicon circuits.  I'm not aware of any current development, nor any commercial releases, but its use was extensively documented in academic literature.
For example:
http://dspace.library.cornell.edu/handle/1813/7223
http://www.cs.indiana.edu/~geobrown/fac98.pdf
http://www.doc.ic.ac.uk/~wl/papers/async94.pdf  — Preceding unsigned comment added by 67.255.4.221 (talk) 01:17, 8 January 2014 (UTC)
thread_title:  Other programming languages named Joy 

message: Although the introduction suggests that Joy is the result of an independent convergent evolution, it is common knowledge that stack-based programming languages have a long history, with Forth being an important development (late 60s/early 70s).  It's unlikely for a computer scientist (or language developer) to not be aware of Forth and to not have been exposed to other stack-based languages such as  Postscript (itself influenced by Forth); especially if developing a language with such striking similarities.  Shouldn't the infobox consequently include Forth under "Influenced by"? 76.10.128.192 (talk) 00:11, 19 March 2015 (UTC)

message: In the example code, , it is explained what the  and  operators do, but it isn't explained what the  does. So, what does it do? This should probably be added to the article. —Kri (talk) 19:00, 9 September 2015 (UTC)

thread_title:  External links modified 

message: The first two code samples are from languages other than Joy, which does not seem ideal. Visiting this page for the first time and browsing for a sample of the code can give the wrong impression.
It also does seem optimal that these two samples constitute half of all the samples on the page.
