I just checked the StringTemplate, and I think you and I have the different understanding of Declarative Programming. This promotes faster development and also make the functionality available for others. Logic-less templates flat out turn their back on this problem, forcing you to solve it awkwardly. Since declarative knowledge is knowledge about something and is easy to express in words or symbols, the best way to demonstrate declarative knowledge is through spoken or written words. This isn’t to say that OOP is the One True Way. An unfolding process is one that, in a stepwise fashion, creates further structure without negating the existing one. Introduction: The imperative programming paradigm assumes that the computer can maintain through environments of variables any changes in a computation process. m("button", "Add") If there's an algorithm that may be better suited for checking whether a number is prime or odd, but we don't use it, it's our fault, not Python's. This is not the case for ERB-inspired tools written in other languages since those templates must also be stored as different files. Life is short, and on top of that, we need to work. ``` Interestingly enough, Unix is a great example of the unfolding of a higher level from a lower one. The main characteristics of such programming languages are direct assignments, common data structures, and global variables. Object-oriented programming languages come with rich libraries of objects, and code developed during projects is also reusable in future projects. The idea behind using as many expressions (and as few statements) as possible is precisely to make JS converge towards some sort of lisp, albeit with quite some more syntax. However, the advantages of object-oriented programming are many. Let's say we want to calculate the set of the ten least prime numbers whose least significant digit is $3$. { title: "Phone 1", required: true, value: ["form", "patient_info", "pri.phone"]}, C++ is an object-oriented programming language and includes concepts like classes, inheritance, polymorphism, data abstraction, and encapsulation which allow code reusability and makes programs very maintainable. You raise many interesting points. This allows you to have field names that contain dots or arbitrary characters. Con’s: anyone can get started. After walking in the low level for some time and solving useful problems, you will have a sufficiently deep understanding of their domain. To see this in action, let’s consider an example in which we want to construct a table to display the information from an array named DATA. Thanks for contributing an answer to Artificial Intelligence Stack Exchange! In the abstract, though, we can identify several general paradigms, a number of which are relevant to us as PHP developers. Reading you I am also reminded of this quote by C. A. R. Hoare: "There is nothing a mere scientist can say that will stand against the flood of a hundred million dollars. would never happen. How about this: In any case, RDBs exhibit the two properties that I consider archetypical of declarative programming: Before RDBs, most database systems were accessed through imperative code, which is heavily dependent on low-level details such as the order of records, indexes and the physical paths to the data itself. At every step, each change (or differentiation, to use Alexander’s term) remains in harmony with any previous structure, when previous structure is, simply, a crystallized sequence of past changes. Now, what are the merits of a dsDSL in contraposition to a DSL? It's very interesting to see how monads can represent computation and help avoid a lot of boilerplate. Note that the "pri.phone" field can now have ". For instance, C's getchar() does not always return the same value. Declarative programming is a programming paradigm … that expresses the logic of a computation without describing its control flow. If generate thoroughly validates its input (and it is both easy and important to thoroughly validate input, since these validation rules are the precise analog of a DSL’s syntax), it will tell you exactly where you went wrong with your input. Excluding logic from templates pushes presentation logic into the server where it is awkwardly accommodated. They do not interact directly with the hardware. I think that the essence of declarative programming is simply to provide a higher level layer that abstracts the repetition patterns of its low level. I’m glad you asked. Declarative programming (also known as functional programming) languages do not attempt to control the flow of a program; they establish desired results i.e. Declarative programming : is a programming paradigm that expresses the logic of a computation(What do) without describing its control flow(How do). [:h1 {:class "text-info"} "Hello there"] Point taken, I never realized this expression was so ambiguous! The patterns of representation are the patterns in which you should be able to express a problem that belongs to the domain that concerns your tool. Compared to that, HTML is amazingly simple and easy to modify. A number of students requesting a number of reference letters. The concept of unfolding comes from Christopher Alexander’s magnum opus, The Nature of Order - in particular Volume II. Advantages of C Language 1. Declarative templating tools, at least when applied to the task of generating HTML views, are an archetypical case of a high level that turns its back on the low level it intends to replace. Signs of a tool with a large complexity gap are: I might have fallen prey to emotion here since template systems are not that complex, but this comparatively small complexity gap is not a merit of their design, but rather because the domain of applicability is quite simple (remember, we’re just generating HTML here). Putting such a "script" in and code block would make you think that the code is "imperative". Why doesn't the fan work when the LED is connected in series with it? Further more for any declarative programming language, the two most important phases are: how information is represented, so the underlying search routine upon this language is based. We write a function named drawAll that will invoke all functions that generate the views. Thank you for that post. This article describes what Competitive Programming is and the benefits of participating in a Programming contest. C++ combined object-oriented and systems programming. This is known as referential transparency. We do this using dale.stop. The things you claim are declarative are not. What I didn't like about it is that you need to invoke the `m` function for every tag, for example: I know Functional Programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data and is not a type of declarative language. We can consider all of them to be similar in that the main mission of template systems is to provide an alternative to code that concatenates HTML strings using conditionals and loops, much like RDBs emerged as an alternative to code that looped through data records. More precisely, code that uses a dsDSL is almost entirely composed of: Code that consists mostly of expressions and which encapsulate most statements within functions is extremely succinct because all patterns of repetition can be easily abstracted. return lith.g (['div', {class: 'well'}, ['h1', {class: 'text-info'}, 'Hello there']]); Now, what the hell are patterns of representation and patterns of generation? Thanks for sharing! It is actually completely declarative, generating HTML and HTML fragments from it is extremely robust and easy. It looks interesting, I hadn't heard of it until you mentioned it. To develop software, the object-oriented concepts need to be implemented in any high-level language. Puppet is declarative, Chef is imperative. ``` We would not go too far if we describe these errors as iatrogenic. A straightforward way to represent an HTML tag in a dsDSL is by using an array with three elements: How to enlarge a mask in Photoshop non-destructively ("bleeding", "outer glow")? Business logic certainly has no place in a template, but presentation logic exists nevertheless. Declarative, in my opinion, is to help user achieve their business with the most readable/maintainable code, in that sense, if user has to put their script there, instead of forcing them to put the script (could be very short) somewhere else, and has to navigate files or lines to read the logic, the let them do (put the script inline with template), I you recommend you design and use your own DSL for the complicated business logic that you face, that's the best way to embrace Declarative Programming. In a nutshell, declarative programming consists of instructing a program on what needs to be done, instead of telling it how to do it. $$. Declarative is not about opting out "script", or limiting its user from using powerful but dangerous tools. Nowadays we have some special syntax for JSX, but it remains pieces of code we put into our JavaScript files. } Machine language is the lowest and most elementary level of programming language and was the first type of programming language to be developed. It is (hopelessly) beyond the scope of this article (not to mention my understanding) to summarize the implications of this monumental work for software design; I believe its impact will be huge in years to come. The heuristic I suggest you to consider is, value tools that illuminate their problem domain, instead of tools that obscure their problem domain behind purported features. This is in contrast with imperative programming, which implements algorithms in explicit steps. Most systems have to supply some sort of special batch job submission facility and a special command interpreter for files distinct from the one used interactively. I know you make a big disclaimer about this being a rant and all. I wholeheartedly agree with your comment. ``` Note: An even weaker justification for a large complexity gap is when a tool is marketed as magic, or something that just works, the opaqueness of the low level is supposed to be an asset because a magic tool is always supposed to work without you understanding why or how. To add insult to injury, these classes of errors have nothing to do with the problem domain but rather with the tool itself. Other template systems suffer because they truly need to provide a non-trivial programming language so their users can actually write presentation logic. (of which I'm painfully ignorant). 2. Declarative programming stands in contrast to imperative programming via imperative programming languages, where control flow is specified by serial orders (imperatives). This lack of unfoldance, if you forgive the neologism, is routinely justified by the necessity to shield the user from the lower level. This is my "make up" template, and I think it's very much "declarative", how do you think? The critique of declarative programming I did above would not apply to other types of declarative programming, like functional programming (which I use constantly and actually make an indirect case for in the second section) and OO, constraint programming, etc. Declarative programming allows you to write more general functions that could potentially be used for multiple purposes. (There might be other dsDSLs out there, but so far I haven’t come across any. As such, I think it belongs to the class of DSLs, and hence the arguments in the first part of the article are relevant. This link gives some insight about its architecture https://gist.github.com/evancz/2b2ba366cae1887fe621. You have read in detail about the numerous advantages of Python programming language. What I would like is a declarative layer that allows me to use more powerful constructs when I need them, but only when I need them. Let’s now step back and contemplate these three quintessential sources of friction, summed up by the concept of separateness. So declarative programming "in the small" is a technique that every programmer uses every day, without thinking twice about it. I also think that the dsDSL approach is fully possible in Lua, thanks to its literal structures. Later I will touch on the issue of whether this approach may be extended to other languages (spoiler: It can definitely be done in Ruby and Python, but probably not in C). We can create the presentation logic that matches this requirement in ~20 lines of code: I concede this is not a straightforward example, however, it represents a fairly simple view of the four basic functions of persistent storage, also known as CRUD. For those who are still with me, I would like to go back to the main claim of this section, which is that a dsDSL has the advantages of both the high and the low level: But how is this truly different from purely imperative code? Like JSON, a dsDSL has the following attributes: But dsDSLs go beyond JSON in many ways. This is a dsDSL at its best. 2. Your first straw man example is not valid, not all templating systems suffer from what you complain about. C is… Read More » There are different was to encode logic in such a way that a computer can process it, and every language has a slightly different spin on the subject. Can there be democracy in a society that cannot count? When the former solution is more complex than the latter, we are in presence of the complexity gap. I still think that DSL-based have systemic issues, which trascend mere "bad design". All software must be architected and layered to manage complexity - the fundamental name of the game. 2. https://lhorie.github.io/mithril/ ", yet most of the times we don't need the verbose format you proposed. Mithrill: I used it a few months ago and became very excited by the fact that it uses plain JS to create views! In the following two sections, I will present the two main problems of declarative programming: separateness and lack of unfolding. I played quite a while with Lua for Redis scripting purposes. What about a part of "you declare what should be" is in "script"? The advantage of a declarative language like Prolog is that it can be used to express facts and inference rules separately from control flow. Procedural programming 1. I was referring to the popular meaning of "steep learning curve", i.e. First walk around it, then slide through it. However, even they admit it comes with trade-offs. Because you're now putting most of your HTML in your JavaScript files, there's very little way for a tool to go in and edit anything. Or when I can use Rosmaro (https://medium.com/dailyjs/state-machines-to-the-rescue-of-complex-forms-867b75790455) to model changes of behaviour in my code. I'd much rather write: `['html', ['body', [['input'], ['button', 'Add']]]]`. Purity is key here. CAVEAT: This article emerged as the result of a multi-year personal struggle with declarative tools. React uses JSX, which is "a JavaScript syntax extension that looks similar to XML". You are struggling to solve a straightforward problem that squarely belongs in the domain of the tool you are using, but the best Stack Overflow answer you find describes a, When this very straightforward problem could be solved by a certain feature (which does not exist in the tool) and you see a Github issue in the library that features a long discussion of said feature with. C language is a building block for many other currently known languages. In practice, I still found it to perform quite fast, even on mobile devices. In practice, this approach entails providing a domain-specific language (DSL) for expressing what the user wants, and shielding them from the low-level constructs (loops, conditionals, assignments) that materialize the desired end state. I will spend the rest of this section explaining why. In the face of this, RDBs provided a tremendous productivity leap for systems developers. code written in this way mostly consists of expressions, instead of statements, Introduction To Concurrent Programming: A Beginner's Guide, The Definitive Guide to DateTime Manipulation, WebAssembly/Rust Tutorial: Pitch-perfect Audio Processing, Billing Extraction: A Tale of GraphQL Internal API Optimization. I cherish the fact that it uses code to generate views, albeit in a structured way. As David points in another comment, similar approaches are employed in other kinds of declarative programming. It is entirely true that in this article I reduced declarative programming to DSLs. With Blind Fighting style from Tasha's Cauldron Of Everything, can you cast spells that require a target you can see? In this section I will attempt to show a way for unfolding a high level tool from its domain. It calculates factorial using recursion:But despite the high popularity level, we have to admit that imperative programming languages can be non-scalable and sometimes to… Declarative programming provides less flexibility. Common declarative languages include those of database query languages (e.g., SQL, XQuery), regular expressions, logic programming, functional programming, and configuration management systems. If you asked me a year ago, I would have thought that the concept of dsDSL was novel, then one day, I realized that JSON itself was a perfect example of this approach! JSX is not like a DSL, at least not in the sense of the article. I understand what you say and it's entirely tree that using arrays of strings is more verbose (for both reading and writing) than just using a string with a dot as a separator. Advantages and Disadvantages of Object-Oriented Programming (OOP) This reading discusses advantages and disadvantages of object-oriented programming, which is a well-adopted programming style that uses interacting objects to model and solve complex programming tasks. Every common high-level programming language lets you express mathematical calculations at a high level, without worrying about the mechanisms of register allocation, table lookups for transcendental functions, etc. I will expound on this issue on a future article. However, there's indeed a bias towards them in practice. But there is one quality that cannot be purchased in this way — and that is reliability. In other words, we want to sweep the low level under the rug, the faster the better. You might be right about JSX - I have used it only very cursorily. Like when I need a stateful http service mock, WireMock (http://wiremock.org/docs/stateful-behaviour/) does an amazing job by letting me describe the whole behavior as a bunch of JSON files. Hi David! If you know of one, I would really appreciate your mentioning it in the comments section.). Create a high level that unfolds from the lower level, to overcome the complexity gap. Any non-trivial web application will have views that are more complex than this. The one I am confused about is Functional Programming. And I still think that DSLs are fundamentally limited. If the patterns of representation are the structures you use to express what you want, the patterns of generation are the structures your tool will use to convert patterns of representation into the lower level structures. An imperative program describes how to do stuff, that is, algorithms. It is good to read again about monads - I think this time I understood them ; ). I would be very interested to read about similar developments in Haskell - or any language, for that matter. And if you enjoy the paradigm and its tools, don’t take me too seriously. Anyway, Lua is pretty interesting and worth using sometimes. Examples of procedural programming languages include C and Pascal. drawTable fulfills the double role of partial and helper. Effectively this is asking if Mary is the wife of David. Chef you have to write all the instructions explicitly to install and configure everything yourself. Hard coding these views into a set of HTML files is not an option because many components of these pages change. Sorry. To create its contents, we use dale.do which is a function like Array.map, but one that also works for objects. What are the main advantages of using declarative programming languages for building AI? Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Where $\varphi$ is the set of all functions, and $\delta_f$ is $f$'s domain. The patterns of representation for HTML are the following: These instances can be represented with the dsDSL notation we determined in the previous section. I completely agree with you - declarative tools that are expressed within the programming language itself (like the Wiremock example you pointed out) are tremendously powerful. You can actually precompile Mithril to eliminate the calls: http://mithril.js.org/optimizing-performance.html In contrast, most mainstream languages, including object-oriented programming (OOP) languages such as C#, Visual Basic, C++, and Java, were designed to primarily support imperative (procedural) programming. Since then, the language has been regularly updated with Java SE 8.0 version being the latest version, released in … It only takes a minute to sign up. A programming language widely used for DSL development, specially on game mod development and configuration management. What was wrong with John Rambo’s appearance? The first is that the template necessarily resides in a file separate from your code. Con’s: anyone can get started. This function receives DATA and FILTER as parameters, so it can be used for different data sets and filters. Functional programming is by definition declarative — your code says exactly what you want to happen and may require less documentation or … An approach that worked well for me is to use arrays of strings to represent paths. "After examining hundreds of template files that I created over years of jGuru.com (and now in ANTLR v3) development, I found that I needed only the following four basic canonical operations (with some variations): A further characteristic of dsDSLs (which we don’t have time to explore here) is the possibility of using types to increase the richness and succinctness of the literal structures. ``` Use MathJax to format equations. Hi Lukasz, This was an over generalization of which I'm now aware - I stand corrected. What is this vial for in this package of grass jelly? I happen to see this as a disadvantage. Moreover, I propose a dual approach that captures the benefits of declarative programming while superseding its limitations. Computer programming language - Computer programming language - Control structures: Programs written in procedural languages, the most common kind, are like recipes, having lists of ingredients and step-by-step instructions for using them. In computer science the declarative programming is a style of building programs that expresses logic of computation without talking about its control flow. Object-oriented programming is often the most natural and pragmatic approach, once you get the hang of it. Similar patterns can be found for generating CSS. - Contents: a string (text), an array (another tag) or undefined (if there’s no contents). Imperative approaches tell the system what to do. The point about views becoming code is very accurate and I don't have a good response to that. StringTemplate for example has no way to embed scripts into it. Hi Lê! stuff as recursive (and algebraic) data types. - Attributes: an object (of the plain, key/value type) or undefined (if no attributes are necessary). Moreover, s (the set we have been defining so far) is defined in terms of the constraints its members must obey, rather than in terms of an algorithm to compute s itself. I am applying this approach to every significant problem I encounter and every time it has worked out fantastically. Machine Language: a language that is directly interpreted into the hardware Assembly Language: a slightly more user-friendly language that directly corresponds to machine language Machine Language. Prolog is a logic programming language associated with artificial intelligence and computational linguistics.. Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is intended primarily as a declarative programming language: the program logic is expressed in terms of relations, represented as facts and rules. m("input"), This allows the developer to focus on the data and inference rules (the knowledge model), and allows the developer to extend the knowledge model more easily. What to do? In fact, lith does both, in ~250 lines of code. There has to be a more accurate and enlightening explanation. About Mithrill and React, you're right that the invocations return first class objects. Within Logical Languages, the programmer ensures that the choices declarative statements. By more complex, I mean more lines of code, code that’s harder to read, harder to modify and harder to maintain, but not necessarily all of these at the same time. I get why you've come down on the side of "it's still logic you need! Although its advantages indeed overweigh its disadvantages, Python does have a few disadvantages that you should know. I do agree that DSL-based systems present a set of challenges that should be approached with caution, but in general I find writing in a declarative style makes it easy to visit code weeks, months, or even years later and understand what the code _should_ be doing (it doesn't always mean that it is, but at least I know what the author of the code was hoping to achieve...if they named things well).
