Talk:Programming paradigm

message: I deleted the following sentence, because it does not make sense:
 Their foundations are distinct models of computation: Turing machine for object-oriented and imperative programming, lambda calculus for functional programming, and first order logic for logic programming.
Reasons for deletion: First-order logic is not a model of computation.  Turing-machines are not specific to the OO and imperative paradigm.  Turing-machines and Lambda-calculus are both universal models of computation and interchangeable.  Imperative programming can be modeled by lambda-calculus.  Functional programs can be compiled to Turing-machines.  In practice, imperative programming relates more to Random-Access-Machines than Turing machines.  — Preceding unsigned comment added by 138.246.2.43 (talk) 14:36, 17 April 2013 (UTC)
thread_title:  Introduction

message: I propose we work towards creating a paradigm hierarchy. For instance, procedural programming is a sub-paradigm of imperative programming, and both are structured programming paradigms. However, in the present state all of these paradigms are listed individually and the relationships between each are not as well defined as they could be.
Though, I recognize not all paradigms fit neatly into a hierarchy, but that information is useful to the reader in comparing paradigms.

replies: text: I agree, I think some sort of hierarchy ought to be imposed. Specifically, I was not aware of many of these "paradigms" and was expecting to just see "the big 5" (functional, object, imperative, procedural, logic) which seemingly ought to be featured more prominently. For instance, recursive is not something which is wholly exclusive of other larger scoped paradigms. --Belg4mit 22:40, 9 April 2007 (UTC)

thread_title:  Hierarchy 

message: I've made an initial effort to categorize the recognized paradigms in a well-defined, consensual hierarchy. I am trying to turn a list into a tree (or a small set of trees). The two major hierarchies I've created are 1) declarative programming (which contains "logic programming", "functional programming", "constraint programming", etc.) and 2) imperative programming (which contains "procedural", "OO", "aspect-oriented", etc.). I believe a well-organized hierarchy gives the reader more useful information for paradigm comparisons than an unorganized list of paradigms. I ask you to help me improving that classification and delimiting orthogonal hierarchies (e.g. "recursive" X "iterative"). --Antonielly (talk) 11:28, 15 October 2008 (UTC)
replies: text: This seems to be a classification you just made up. Lisp is not a declarative programming language. --FOo (talk) 01:27, 16 October 2008 (UTC)
replies: text:  Both the article about declarative programming and the :Category:Declarative programming languages consider functional programming languages as declarative (instead of imperative). See also the corresponding entry at Encyclopaedia Britannica, which says that both functional languages and logic languages are declarative. Of course, someone could define declarative programming in such a way as to exclude functional programming, but most of the material I've read about the subject (in books, papers, etc.) seem to conventionally imply "declarative" as a rough synonym of "non-imperative", which would include functional languages (as far as they follow the functional style, at least).

message: User:LinguistAtLarge has had the smart idea of transfering the contents of the "Hierarchy of programming paradigms" section to the Template:Programming paradigms.

message: I think there's a fundamental disconnect with this article and it starts with piece on lambda calculus. There is need of a bridge between the historical work and computing languages: Ada Byron developed some notation for the algorithmic computing, so programming paradigms should trace back at least to her. In 1963, John McCarthy wrote a seminal paper A basis for a mathematical theory of computation found In Computer Programming and formal systems. North-Holland. McCarthy's paper is a bridge from what we have today and the Church, Turing, Kleene work. McCarthy's basic argument was that recursive functions were the natural setting. Denotational semantics is the natural outgrowth of McCarthy's ideas by way of Strachey and Scott.

I removed the claim that Scheme is designed to support one particular paradigm. It supports virtually *all* known paradigms. It is biased towards functional programming, but this seems fine: Python and Ruby are as well biased (towards OO). And by the very tiny R^nRS and IEEE standards there are at least two direct supported programming paradigms from standard (functional and imperative). Scheme being extensible, we may take OO, logic programming and other common paradigms for granted, because they really are embedded in the language by most implementations. --189.12.148.237 22:09, 5 July 2007 (UTC)

message: == Suggested improvement to the History section ==
It looks to me like the History section has become a bit tangled up do to a confusion between paradigms and languages.  For example, I don't think that assembly language is a paradigm. It's entirely possible to write assembly code using any paradigm imaginable.  It might not be elegant or productive, but it's possible.  I've personally written code that shoe-horned an OO paradigm into ANSI C, a language listed as "procedural."  It wasn't pleasant or pretty, but it solved the problem at hand better than any alternative I could come up with.
I think that this confusion may have driven the long defense of assembly language in this section. It seems out of place, but I think I understand why someone felt the need to put it there.  Nobody likes to see his favorite language under attack as outdated, particularly by someone who seems to know far less about the subject than he does.
Before I jump in and attempt to rewrite the section in a way that clearly separates paradigm from language and avoids the appearance of declaring one paradigm fundamentally superior to another, I'd like to see if anyone objects or has other comments or ideas. Anyone?

replies: text: I was in the audience for an Alan Kay keynote once and this is 100% true. For Kay, object-oriented programming is not about what the programming language looks like, it is creating software environments using direct manipulation in a GUI and using programming to script behaviour of the objects shown in the GUI. This is what Smalltalk allows, HyperCard, Visual Basic, Delphi, .NET languages with GUI-manipulating IDEs, etcetera. I don't think this is what the term "object-oriented" is taken to mean by 99.9% of the people who use it.  Some people use "visual programming"  to describe it, but that term can also have other meanings. Rp (talk) 09:40, 29 January 2015 (UTC)

replies: text: No, "GUI programming" is not what Alan Kay means. You also need an environment that lets you create and modify the GUI graphically, without programming. For a compiled language, this means the GUI programming code is generated automatically and the designer normally doesn't even need to see it. I agree this is not what the article should define as object-oriented programming, but it is what Alan Kay means when he talks about it. Rp (talk) 11:16, 30 January 2015 (UTC)
replies: text:  Well, now I might be slightly confused. :)  Does he refer to the programming tools that automatically generate "code behind" the GUI elements, so a developer (or whoever deals with the GUI elements) never needs to write it by hand?  In that case, the real programming is all about filling in event handlers and such stuff, beside implementing the internal program ("application") logic.  If that's what he speaks about, then I'm not so confused. :) — Dsimic (talk | contribs) 12:54, 30 January 2015 (UTC)
replies: text:  Yes, but historically, that is the wrong order of thinking about it.  First there was Simula (which didn't really have a GUI system, as far as I know). Then there was Smalltalk, which Kay worked on; it came with all this. Then came C++ which was based on C and Simula, not on Smalltalk; again, no GUI support. Then came OO-based GUI programming without GUI builder support , e.g. X programming or GUI programming in C++ or in Java. I think what Kay was saying in that keynote is that that just misses the whole point of what he was trying to do. Rp (talk) 17:16, 1 February 2015 (UTC)

thread_title:  Suggested improvement to the History section 

message: Some wiki nimrod, in their infinite ignorance, merged "general-purpose programming language" into domain-specific language (reasoning in elegant and pointless germanic logic that they were opposites and therefore obviously mergeable). This led to a circular reference, since the domain-specific language page was one of the main wiki pages referencing "general-purpose programming languages" (seriously, the wiki Vogons have got to learn how to proofread and check their changes... they aren't Gods, despite their personal notions).
Someone later fixed the circular link by linking "general-purpose programming language" to "programming paradigm" -- here.
But a "general-purpose programming language" is really just the opposite of a special-purpose programming language -- they exist in a two-state universe, i.e., general-purpose vs. special-purpose. They are NOT programming paradigms, but rather types of programming languages.
"General-purpose" means applicable to solving general problems. This would be the general class of most programming languages, like Fortran or Haskell.
"Special-purpose" means designed to solve a smaller set of problems in a well-defined context. For example, SAS is a language for writing statistics applications.
Yes, yes, we could have arguments about the language beasts that appear as general-purpose to one set of blind men (PHP), and as special-purpose to another set of blind men (PHP). You could probably do this for every programming language ever invented -- Fortran is for scientific formulas, Cobol is for business apps, Haskell is for humoring mathematicians, etc. etc.
In the previous section it was stated: "It looks to me like the History section has become a bit tangled up due to a confusion between paradigms and languages". This was in regard to sticking Assembly Language under "programming paradigms". This is the same problem -- you can cut the computer/software engineering cake many different ways... but some of the pieces from different cuttings just aren't comparable or even in opposition, they really cover different or overlapping topics and issues.
Computer languages are related to programming paradigms, but they are not paradigms in and of themselves.
Computer languages are an implementation detail. A programming paradigm supports the big picture. How are we going to solve this problem? Not, with what gizmo are we going to solve it? Programming Paradigm equals Method. Computer Language equals Gizmo.
Some gizmos are high-level, some are low-level (like Assembly Language). Some gizmos are general-purpose, able to solve many types of problems, and some are special-purpose, most useful when trying to solve a much smaller set of specialized problems. But a gizmo is what you solve a problem with, it is not the method used to solve the problem. We need water. We dig a well. Digging a well is a paradigm. A post-hole digger is not a paradigm, even if it can be used for digging wells.
If the word Gizmo bothers you, substitute the word Tool instead.
When you hire your so-called computer expert from some WikiProject, hopefully he/she will know their ass from their elbow and will straighten out this mess.
I'm not holding my breath.

thread_title:  I reacted to the top of the page comments 

message: I have serious reservations about the usefulness of this term. For one, almost every language out there is a fusion of ideas and approaches; ergo multi-paradigm in some sense. And secondly, to say a language is multi-paradigm doesn't really tell you anything about the language. If you asked someone what kind of language Ruby is and they said "Ruby is multi-paradigm" you wouldn't go "Ahh, right, that's interesting," you'd go "OK. Which paradigms?"
My main objective in making this point is to remove "multi-paradigm" qualification from paradigm section of those side-info boxes on each programming language. The article of multi-paradigm itself serves as a definition for the term which may be useful to someone expressly seeking it out. Ruby is a particularly bad example as the side-info box lists Ruby's paradigm as "multi-paradigm" and nothing else, which tells you virtually nothing.
Another option is to limit our usage of the multi-paradigm term to those languages that merge the most significant paradigms especially where those paradigms are not normally seen together. For instance OCaml is an interesting merge of object-oriented and functional paradigms but a language that merges OOP and reflective really isn't interesting because many OO languages have reflective features. Oligomous (talk) 13:40, 4 March 2010 (UTC)
thread_title:  Is multi-paradigm a paradigm? 

message: The articles states "A programming paradigm is a fundamental style of computer programming," and I agree. But, despite that definition, there seems to be a number of things listed as paradigms that I wouldn't consider so. For instance, is metaprogramming a "fundamental style of computer programming"? I'd say it's a style or with an associated collection of features and ideas. I know there were some esoteric languages created that exhibited aspects (as in aspect-oriented metaprogramming) as their primary means of abstraction (in opposition to objects, say) but these didn't work very well.
Whilst I like all these articles—reading about agent-oriented, intentional, or reflective programming is interesting—I'm hesitant to refer to them as paradigms when paradigms are fundamental styles or programming. Could they not be better classified as approaches to software construction or simply programming styles? Oligomous (talk) 13:55, 4 March 2010 (UTC)

replies: text:  Well, now I might be slightly confused. :)  Does he refer to the programming tools that automatically generate "code behind" the GUI elements, so a developer (or whoever deals with the GUI elements) never needs to write it by hand?  In that case, the real programming is all about filling in event handlers and such stuff, beside implementing the internal program ("application") logic.  If that's what he speaks about, then I'm not so confused. :) — Dsimic (talk | contribs) 12:54, 30 January 2015 (UTC)
replies: text:  Yes, but historically, that is the wrong order of thinking about it.  First there was Simula (which didn't really have a GUI system, as far as I know). Then there was Smalltalk, which Kay worked on; it came with all this. Then came C++ which was based on C and Simula, not on Smalltalk; again, no GUI support. Then came OO-based GUI programming without GUI builder support , e.g. X programming or GUI programming in C++ or in Java. I think what Kay was saying in that keynote is that that just misses the whole point of what he was trying to do. Rp (talk) 17:16, 1 February 2015 (UTC)

thread_title:  Concept Programming 

message: I know a little about specific programming languages but I think I know less about programming after reading this article.
I've read through the article twice and I think more vivid and descriptive language could be used to describe the differences between paradigms. How about some quotes from scholars who created these languages or defined these paradigms?  Or some examples or analogies. And that flow chart is a complete mess, it is overly detailed and looks like it belongs on another article. I think 95% of the terms in the image are not even mentioned in the article.
This is an article for a general reader and, considering what an important subject this is, this article is just a wall of dull text (blah blah, blah blah blah) that neither engages the reader or makes them curious to learn more. It's an interest killer. Liz Read! Talk! 21:50, 5 June 2014 (UTC)
replies: text: Hello there!  Hm, article looks fine to me; at the same time, I'd agree that it might be a bit dull and perhaps a bit too complicated, but it's quite tough to explain such an advanced topic in plain words that would be understandable to just everyone.  In other words, my opinion is that any significant simplification would lead to lost details, what wouldn't be a good thing. — Dsimic (talk | contribs) 20:27, 8 June 2014 (UTC)

message: Aspect-oriented Programming(AOP) appears not to be mentioned in particular. I think it should be.
See: https://msdn.microsoft.com/en-us/magazine/dn574804.aspx?f=255&MSPPError=-2147217396
or: https://en.wikipedia.org/wiki/Aspect-oriented_programming
Read either of the citations for an exact description.
An over simplistic overview: 
AOP is a declarative programming paradigm that is usually applied to an OO or Service Oriented Architecture;
Although it could be used in any paradigm. Some would say it is of itself not a new paradigm rather a mixture of declarative and other  paradigms.
AOP cross cuts concerns.
e.g. Logging needs to be applied to all aspects of an application. However, you do not want to hard code logging into every point you want logged; e.g. informational logging at every entry and exit of a method. This would break the DRY principle.
You write the code once and declare an Aspect in the main program to tie that code to all the places you want that code called and the insertion of the code is done as part of the build process.

:I don't think this is really a paradigm. It got a lot of press for a while, and it has a few implementations, but I'm not aware of any AO languages; as far as I'm aware, implementations are preprocessors available for some OO languages. I'd call it a technique rather than a paradigm: it doesn't fundamentally change how programs express what needs to be done. Then again, C++ started out as a preprocessor for C, and C#'s extension methods are AO-ish. Rp (talk) 19:18, 8 August 2018 (UTC)

thread_title:  Programming Paradigm vs. Programming Language Paradigm 

message: First sentence: "Programming paradigms are a way to classify programming languages based on their features." is not wrong, but so generic it lacks value. There are many ways to classify languages (or anything). The programming paradigm is a rather particular way to do so. I agree that it's hard to describe, but someone needs to take a stab at a real definition. The second paragraph takes a shot at it by listing some examples, but examples are not a definition. What is it? 
Oxford says paradigm is "a worldview underlying the theories and methodology of a particular scientific subject." I'd say that is close.
How about: Pervasive conceptual view that a language is designed to model.
