## What is Haskell Programming Language?

The classic Haskell programming language for iPad, iPhone and iPod touch. Programming language is a perfect tool for studying, complex mathematical calculation, entertainment and many other useful tasks. The application is especially useful for learning the Haskell programming language. You have to buy compilations inside the application. Internet connection is required. 

- The great programming tool on the AppStore. 
- Your programming language for iOS is amazing! 

* FEATURES * 

- Compile and run your program. 
- Text input before program run and text output. 
- Enhanced source code editor with syntax highlighting, line numbers, color themes and additional keyboard.
- Online language reference and several program samples. 

* LIMITATIONS * 

- Internet connection is required to compile and run a program. 
- Graphics, network, file system and real-time input are not supported.
 
- Maximum running time of a program is 15 seconds. 

Thanks for using the application! 

====================================== 

Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing. It is named after logician Haskell Curry. In Haskell, "a function is a first-class citizen" of the programming language. As a functional programming language, the primary control construct is the function.

Following the release of Miranda by Research Software Ltd, in 1985, interest in lazy functional languages grew: by 1987, more than a dozen non-strict, purely functional programming languages existed. Of these, Miranda was the most widely used, but was proprietary software. At the conference on Functional Programming Languages and Computer Architecture in Portland, Oregon, a meeting was held during which participants formed a strong consensus that a committee should be formed to define an open standard for such languages. The committee's purpose was to consolidate the existing functional languages into a common one that would serve as a basis for future research in functional-language design.

Haskell features lazy evaluation, pattern matching, list comprehension, type classes, and type polymorphism. It is a purely functional language, which means that in general, functions in Haskell do not have side effects. There is a distinct construct for representing side effects, orthogonal to the type of functions. A pure function may return a side effect which is subsequently executed, modeling the impure functions of other languages.

Haskell has a strong, static type system based on Hindley–Milner type inference. Haskell's principal innovation in this area is to add type classes, which were originally conceived as a principled way to add overloading to the language, but have since found many more uses.

The construct which represents side effects is an example of a monad. Monads are a general framework which can model different kinds of computation, including error handling, nondeterminism, parsing, and software transactional memory. Monads are defined as ordinary datatypes, but Haskell provides some syntactic sugar for their use.

The language has an open, published specification, and multiple implementations exist. There is an active community around the language, and more than 5400 third-party open-source libraries and tools are available in the online package repository Hackage.

The main implementation of Haskell, GHC, is both an interpreter and native-code compiler that runs on most platforms. GHC is noted for its high-performance implementation of concurrency and parallelism, and for having a rich type system incorporating recent innovations such as generalized algebraic data types and type families.

### 1/5 — Basically worthless

*2022-09-03, version 13.0*

Will not compile anthing but the Hello World example.

### 3/5 — It works but could have a few updates

*2021-05-07*

Would be nice to have the option for spaces not tabs as an indent. Default is one tab which doesn't play nicely with Haskell.

Also, some auto completion of variable names etc...

### 5/5 — Reviewer “App_Known” is Precisely Correct

*2020-11-22, version 13.0*

It’s become increasingly difficult to believe ANY review, as people have become SO aggressively attacking in their comments. They say things in text that (I hope) they would NEVER say in person! In this app, the price for “unlimited” is basically FREE. What’s wrong with these “people”?!

To the developer: PLEASE IGNORE the idiots who expect EVERYTHING for free! Let them work FOR LESS THAN minimum wage, for FAR LESS THAN an hour!

THANK YOU, DEVELOPER, FOR ALL YOUR EXCELLENT WORK!!!

### 5/5 — Works like a charm!

*2020-04-08, version 13.0*

I had to fix the biased reviews on this app. Haskell is amazing and this app is impressive and ‘functional’ and a wonderful opportunity to practice Haskell from anywhere in the palm of my hand. Such power!!! Some users can be the biggest babies about things that are totally good for them. Thanks Developer!!!

### 5/5 — Great way to learn Haskell

*2019-11-18, version 13.0*

This is an excellent app with a reasonable pricing model. I’m puzzled by the negative reviews that are ostensibly by other engineers who seem to believe they are uniquely entitled to compensation for their work. This app is worth MORE than the small price for unlimited compiles.

### 3/5 — External library support

*2019-10-31*

This for me is a handy App for testing some concepts and experiments. I have not yet discovered whether it can handle external libraries - I get an error when adding a line such as import Lens.Micro . Maybe there is a way to include libraries.

### 5/5 — Haskell Programming On The Go

*2019-10-17, version 12.0*

I am learning Haskell. This little gem let’s me practice on the go for a very reasonable price. Keep up the good work, D!

### 1/5 — Crapware

*2019-08-07*

This app doesn’t do anything and is simply here to have you spend money.

### 1/5 — No point in making it free

*2019-03-20*

If you're going to charge people for compilations, just make the app paid so people don't have to waste time figuring that out. As it currently stands, you NEED to buy an in-app purchase to use this app.

Just use tryhaskell.com (for free) in Safari if you really need to use Haskell on a phone.

### 1/5 — Won't let you compile

*2017-01-31, version 9.4*

I've compiled ZERO times, and it won't let me compile even once. You have to pay for each compilation. Why?

**Developer response:** Unfortunately, we can't offer free compilations with the application. But you can compile and run the sample program for free.
