Talk:Scala (programming language)

management and threading model, but introduces many advanced concepts. On the functional programming side, these include anonymous functions, optional lazy evaluation and call-by-name, pattern matching and algebraic types, and prominent support of immutable data structures—provided by way of its required standard library. Scala has a more unified type system than Java: There is no distinction between statements and expressions, none between primitive types and reference types, and values and types can both appear as (method or constructor) parameters or (class or local) members. Language elements can often appear in any scope, for example classes, methods and symbol imports can appear in any nesting level, and block expressions can be written anywhere.

that this might be difficult to understand for someone not familiar with these terms? How to do this? P4 says something about Scala's syntax from the Java perspective (arguably the main source of adopters), P5 and P6 are somewhat disconnected: Talking a bit about Scala's novel contributions, and the concurrency paradigm (which is generally associated with Scala).

questionable if any of the others satisfy Knowledge's notability criteria. Maybe those can me mentioned here in a chapter about tooling with a short description of what they are responsible for in the tool chain (I think tool graph does describe it better). Maybe together with an SVG visualizing the relations between the tools. What is your opinion?

3570: 1946:

think the second needs someone more familiar with this programming paradigm, because it goes into a lot of detail. As a general comment, I believe that the amount of detail should be reduced, which would be easier with a rewrite. The problem is I don't know what to take out, or how to group things. Maybe you can take a shot at a rewrite?

1908:

I edited the first paragraph for tone as an example. The "source" for elegance was removed since it was not supporting the argument that Scala is elegant. Similar tone editing can be done for the second paragraph. The amount of technical information (the way it is presented is one of the typical ways

1765:

Here is my take on it (no references, -sigh-). Paragraph 1 should give a good overview of its scope. P2 than describes its environment (JVM) and gives examples of what it offers in terms of functional and OOP. P3 highlights Scala's type system, arguably the most important part of the language. I feel

1729:

While technically the JVM exhibits type erasure, it would be misleading to call Scala's concept of "reified types" a work around. It really is a clean solution to type erasure. More so since Scala 2.10, where "manifests" are replaced by "type tags" which fully represent the Scala type system, meaning

pivot))" will only replace one problem with another: now, the pivot value will be represented only once in the sorted output even if it was present multiple times in the input. I think the "solution" is to replace the existing example with the one above . Maybe I am misunderstanding something here.

1336:

Based on numerous recordings of the author on Youtube and similar sites I have chosen the IPA "ʌ" (respell "u"); some may debate that "a:" is more correct, but at least such a debate would be somewhat dialectical, rather than any support of schwa, which is simply misguided, or at best a result of the

990:

IMHO, if 'unique' is kept, it should be supported by an external quote / citation. Alternatively, what about calling it a 'novel' approach. The way Scala can be extended is indeed strikingly different from what we know of other mainstream languages (It's not dynamically rebinding a prototype and it's

1794:

Scala's syntax uses curly braces and focuses on ease of adoption for programmers coming from Java. While one can use a style akin to Java, "idiomatic" Scala encourages immutable over mutable variables, functional over imperative style, and the type-safe use of the Option class instead of null. Scala

1786:

Scala programs commonly run on the JVM and are compiled to Java bytecode. Good interoperability with Java libraries is a major goal. Several ongoing projects exist to bring Scala to other platforms such as .NET and JavaScript. On the JVM, Scala shares the basic properties of Java, such as its memory

1707:

This part: "It cleans up what are often considered to have been poor design decisions in Java (e.g. type erasure" is at least misleading if not completely wrong. Type erasure in Scala is still present. There are workarounds, yes, but it is not solved(or "cleaned up") by the language at all. The same

1275:

The given pronunciation doesn't seem right. The main author of Scala (Odersky) pronounces it (in the podcast referenced by the article, for example) as the Italian word (meaning stairs, stairway, ladder etc.). Something like /'ska:la/ in fake IPA. I'm not sure how to show both pronunciations in Wiki

3541:

Currently Scala supports as stable 3 versions of the language: 2.12.x, 2.13.x and 3.3.x. However, only 1 of them is displayed as newest stable: 2.12.5. This is doubly wrong: 2.12.5 is not the newest in 2.12.x line (that would be 2.12.11) and the newest stable Scala in general is 3.3.0. This data is

1790:

Scala's type system is particularly elaborated. It has a top, a bottom and a unit type, it can express higher-order types, singleton types, intersection types and multiple inheritance through mixin composition, it supports type bounds and declaration site variance, and provides path-dependent types

3372:

Early in the section there is a list of functional features of Scala that seem to be meant to highlight the differences from Java, however, type local inference was introduced in Java 10 and expanded slightly in Java 10(albeit not to extent of Scala). Should this be removed or clarified that while

1945:

In my edit of the first paragraph I had as a model the way other languages are presented in Knowledge. I am a programmer myself but I have little knowledge and experience in functional programming. While the first paragraph was general enough to be edited by a non-expert in functional languages, I

I realise this is a bit rude these days, but after three supporting comments spanning 2 years, the last of which is now more than three years old, I'm just going to change the last syllable of the noted pronunciation. There is no reason nor precedent for the final vowel to be a schwa (ə). Indeed,

1179:

Maybe I'm wrong, but I think the example has a bug: What happens if the pivot element is in the list more than once? For example: "2, 2, 3" In this case, the result of sorting would be "2, 3", because every element with the same value as the pivot element is filtered out, but only one element with

1782:

Scala (/ˈskɑːlʌ/ SKAH-lu) is a programming language which blends the paradigms of object-orientation and functional programming. It is statically typed with advanced language features, while still trying to be concise and elegant and maintaining the feel of a dynamic language. The name Scala is a

1630:

From the article: "The name Scala is a portmanteau of "scalable" and "language"..." That's not at all like the typical portmanteau, and much more like an acronym, as it's using only initial elements of each component, and the terminal of neither. Someone have a source calling it a portmanteau,

The design of Scala acknowledges the fact that in practice, the development of domain-speciﬁc applications often requires domain-speciﬁc language extensions. Scala provides a unique combination of language mechanisms that make it easy to smoothly add new language constructs in form of libraries:

1351:

I disagree with the above editor, you certainly can’t say that a schwa is unnatural in English. A schwa in Scala would make the most sense if you don’t stress the final syllable, same as you would in Java /ˈdʒɑːvə/ and koala /koʊˈɑːlə/. I don’t know of any case of a syllable final /ʌ/ other than

3429:

There are so many tools around Scala: SBT, Mill, Coursier, Bloop, Metals with implementations for different editors respective IDEs, the legacy Eclipse based Scala IDE and probably more. That can be confusing. As far as I can see until now only SBT has a dedicated article on Knowledge and it is

1839:

In general, someone should go radically through that article and give it a half way consistent touch (and probably cut away some parts). Right now it just feels like a dump of each and every feature that is available in Scala. Why is delimited continuations mentioned, but not XML literals? Many

985:

I didn't write the first comment about it being too self-promoting, but it certainly has that feel. Here's an example sentence: "Scala provides a unique combination of language mechanisms that make it easy to smoothly add new language constructs in the form of libraries". The word "unique" is

1156:

I have studied Scheme and Haskell at a university course (and a bit more of Haskell), and I still remember that feeling (I mean, I never got really used to functional programming, unfortunately), so I'm arguing this even if I'm no expert. And all my previous contact with Scala was a paper with

1505:

In an ideal case, the pivot would be set to the median of the values contained in the list. Choosing a number in the middle of a list of randomly distributed numbers would not improve speed at all, only harm it by adding a division to every recursive call (Though division is also considered a

1152:

Just my opinion: the existing example is meant to be a direct translation of the Erlang example, and allowing the reader to compare the syntax on the same code is important. For me the current example is quite easy to understand and has a more "functional" style. And yep, the point is that in

1757:

I feel the current introduction paragraph(s) are really poor and messy. Neither are they well structured, nor do they strike a good balance between conciseness and detail. In some questions they go into very specific details, while some things are almost identically repeated across different

2002:

In the section "Features (with reference to Java)" the third paragraph makes a bold case that Scala has significantly more features than Java which make the language "theoretically cleaner". This is a highly promoting tone, that should at least be backed up with references if not completely

The design of Scala acknowledges the fact that, in practice, the development of domain-specific applications often requires domain-specific language extensions. Scala provides a novel combination of language mechanisms that make it easy to smoothly add new language constructs in the form of

3349:), one of the main contributors to Scala and the co-founder of the company behind Scala should be more relevant than what some random CTO says. Also, the creators of Kotlin described why they invented their own language instead of using Scala, which also offers some insights. There is also 1551:

Scala is a pure object-oriented language in the sense that every value is an object. Data types and behaviors of objects are described by classes and traits. Class abstractions are extended by subclassing and by a flexible mixin-based composition mechanism to avoid the problems of multiple

1153:

functional programs one line of code can express much more than in imperative ones, so they're too short for the imperative programmer to understand, but that's the coding style I've seen used by experienced programmers most of the time, so IMHO one just has to get used, and I'd keep this.

1835:

I think the article would benefit from adding a version history section (perhaps with or under history). This would allow to concisely introduce named/default arguments, reified generics/reflection 2.10, macros, delimited continuation (if at all), parallel collections (if at all), string

1998:

Lines 2-3: "were inspired by criticism of Java's shortcomings". The "shortcomings" part is an opinion. We could write that the language was inspirted by criticism of Java, as criticism can be subjective. Adding the phrase "of Java's shortcomings" makes a statement that the criticism is

1561:

Scala is a pure object-oriented language in the sense that every value is an object. Types and behavior of objects are described by classes and traits. Classes are extended by subclassing and a flexible mixin-based composition mechanism as a clean replacement for multiple inheritance.

1990:

I'm a beginner in editing Knowledge articles, but I have a few comments. Firstly, I think this section should be merged with section 3 - promotion, as it discussed a similar problem with this article. In addition, I have a few other edits to help balance the tone of the article:

1843:

The introductory I just wrote (above) already suffers from being too long. The article needs a good concept of nesting the information. Perhaps some stuff could even go into separate articles (e.g., Scala collections, Implicits (unique concept of Scala), perhaps Scala vs. Java).

530: 3473:

Done. I changed it to `+=` to illustrate how operators can be defined and called in infix notation. I also changed the Java version to `addPoint` instead of `addToGrid` because it really just adds any point and only adds to grid when it's called on the grid instance.

1036:): Q: Does Scala work on .NET? A: There are plans for Scala to run on .NET, and the previous version of Scala ran on .NET, but the current version does not. While .NET has many similarities to Java, it has enough idiosyncrasies that the port is non-trivial. -- Phouk 254: 3392:

The article says scala has algebraic data types, but I think that's misleading. It doesn't have native support for them in the way that Haskell or Rust does. Instead They are sort of simulated by case classes. Agreed? Article should be edited accordingly?

2471:

It takes a function with one argument and it embeds it to another function which is then returned. The above example is not currying because the returned function is not a single argument function. However, it shows that Scala has syntactic support for

1386:

This article does not say whether Scala allows imperative (non-functional) programming style. Please ammend the article with an answer on the question whether Scala is a purely functional, mostly functional, or both functional and imperative language.

1802:

While it is often described as specially suited for concurrent programming, Scala advocates library based solutions over built-in language constructs. For example, actors, futures and software transactional memory are provided through libraries.

1355:

However, Martin is a German and will more naturally say Scala without a schwa, so the ruling on /ˈskɑːlɑː/ is fine by me, but most English speaking programmers will prefer /ˈskɑːlə/, so I’d appreciate both being listed as valid.

1798:

Scala also adds some novel constructs such a scoping rule called "implicits", a way by which the compiler is able to automatically fill in parameters. Implicits are used to define type classes and extension methods in Scala.

153: 1006:

Scala might be very good, of course. But the words "performance", "speed", "scope", and "memory" do not appear in the current form of the article, so it doesn't have the feel of a dispassionate examination of the language.

1494:

I think the partitioning of the collection was not done correctly, pivot is the element in the middle of the sequence, in the traditional quick-sort algorithm. Moreover a good typing would use Seq instead of List or Array.

1401:

From what I understand, it supports scripting / imperative style, object oriented style, and functional style. It also implements the actor model for concurrency. I think all of these things should be added to the article.

1093:

Scala can call Java classes or use its jars, but the opposite isn't true: Java can't interact with Scala methods or classes (at least, not easily). This makes Scala not interoperable with Java. This isn't mentioned enough.

986:

particularly objectionable. There are (at least) thousands of interpreted languages out there. Is scala truly the only one for which it is "easy to smoothly add new language constructs in the form of libraries" to?

1930:

Thanks. Could you edit the second paragraph as well? I took a look at it, but I'm not sure how I'd go about it. Usually better to make the edits you desire as apposed to fly-by tagging and leaving it for others.

1761:

It is indeed difficult to write a good introduction to Scala that strikes that balance. So my suggestion is to elaborate a bit on a new introduction in the talk page, before messing around with the actual article.

3494:

The section about Concurrency describes how Scala no longer provides native support for actors, relying on the third-party platform called Akka. The text also states, though, that Akka is an open-source platform.

2974:

where methods need eta expansion to be converted to functions. Technically speaking only foo3 is a (curried) function, the other two are methods. Calling foo2 a curried function, but not foo1 doesn't seem right.

Any objection to deleting the "Companies" section? Scala was broad acceptance now, as indicated by the immediately preceding "language rankings" section, and the "companies" section has become merely a spam pot.

1783:

blend of "scalable" and "language", signifying that it is designed to grow with the demands of its users. It can be employed in diverse scenarios such as lightweight scripting or distributed server applications.

1646:

I agree actually, I would even say it seems that Scala is just the first five letters of "Scalable". Furthermore, the cited reference () doesn't seem to discuss about anything such as a portmanteau word.

1223:

No discussion about the performance cost of advanced Scala features is present. I have reasons to believe their support for advanced features has some cost, some discussion about that is present here:

3543: 3315:, shouldn't the text "To make it clear that all expressions are functions," instead read "all functions are expressions"? I'm learning Scala and this is a helpful article but that bit confuses me. 393: 3475: 3316: 1650: 3044:

i'm not very familiar with java but as i can see, the function getX() and getY() were defined, but never used. Therefore, i don't think this comparison is fair because the java code is bloated.

554: 1605:

There may be more; I see nothing on Scala's site indicating that the text was released under Creative Commons. I'm hoping someone will verify that I'm not overlooking something obvious :) —

Consider it's TIOBE ranking falling to 0.5%, or books about Machine Learning available now, that are now explaining Apache Spark programmation with the help of Python and not Scala anymore.

It should also be noted that the proper pronunciation (which is skah-lah) can be found in a footnote on page 3 of "Programming in Scala" by Martin Odersky, Lex Spoon, and Bill Venners (

that we can then ascribe to that source? Or perhaps better to play safe, and call it as "blend"? (Albeit a somewhat redundant one, since the "la" is (initial) in both root words.)

The BSL requires that the code licensed revert to an approved open source license (“Change License”) after a period of time (“Change Date”) which can be no later than 4 years.

611: 549: 44: 3589: 3693: 472: 482: 1416:

A Scala program can be purely imperative, purely functional or a mix of both styles. It is advisable to minimize or eliminate imperative coding involving concurrency.

1333:

the schwa renders it quite difficult to pronounce and, ignoring the fact that it has already been explained not to be a schwa, is an entirely unlikely pronunciation.

3638: 1525:

Some source links seem to point to wrong or dead resources (e.g. would point to .NET if the link were not dead, although the text talks about Java Micro Edition).

3698: 3255: 3251: 3237: 3356:

Also, the general criticism of Scala breaking compatibility, having poor tooling and being too complex should be mentioned, if reputable resources can be found.

1738:). It is not possible in Java to create a "workaround" that would come any near this approach. Indeed, the article should include a section on type reification. 1580:

A joint use of both features facilitates the definition of new statements without extending the syntax and without using macro-like meta-programming facilities.

A joint use of both features facilitates the deﬁnition of new statements without extending the syntax and without using macro-like meta-programming facilities.

3678: 3456:

I don't speak Scala (that's why I was here), but could someone with knowledge of both languages correct the example so it's possible to interpret precisely?

1735: 383: 3708: 828: 448: 204: 3688: 1097:

Maybe Scala had for goal to address issues of Java, but currently it's learning curve put it among the programming langages the most difficult to learn.

For Scala 2 I think the claim was perhaps debatable, but with Scala 3's `enum` algebraic data types are directly and unambiguously supported, IMO. See

I'm not expert enough in functional programming to identify the difference, but does this Odersky document convey actual currying on page 23?

The lead reads like promotional material for the language. It actually creates a hype. The wording is far from optimal in many cases.

1654: 1632: 1461: 1423: 1388: 1065:. I think that it should be edited, since as it is written now, it seems that .NET is fully supported, which is not quite the state. 3153:

The confusion is likely due to Scala not having static methods. The closest equivalent to importing static methods in Scala would be

Agree, my mistake. I was confused by the equivalence of partial application and currying for two-argument functions.
