Let's start. API♪ This is the simplest option: an opportunity to apply to the code outside this annex. This is a set of functionalities to make the programme &apos; s external essence do its work.Example real life: you have a plumbing in your apartment, and API is a plumber phone that this plumbing can fix if you need to.Now, Library - it's a ready-to-use code that runs in the context of the application, and it's also doing its work. So the library becomes part of the application. The difference between the library and API may be quite delicate: for example, WinAPI provides functionality, which, in general, sometimes occurs within the process. However, this is considered to be an application to the outside platform.Example from real life: you don't smash the closet yourself, you buy the house ready, put it in your apartment and use it. The scarf is your connected library.Yeah. Framworth - his functions, unlike the library, are not summoned by you, and vice versa, your code comes from him. Freamworth can be imagined in the form of a semi-finished annex to which you sign the required functionality yourself.An example of real life: you buy an almost ready apartment, and furniture, wallets and closets add to yourself. The apartment is your Framworth, it's almost ready. You can't just redo the number of rooms or turn it into a ship, but instead you just add internal functionality: park floor, machro robe in the bathroom and cat.

Business logic is the logic of your application. Freimvork is a set of libraries that conduct standard routine operations.For example, if you write an annex for a public bath, the business logic will contain a description of the user profile, schedule, search for free space for booking, etc. In doing so, it can use a fluoride for such things as contact with the base, work with the parameters of the request, dependency injection, postal work, etc.

Syntaxis in the pre-processors is very similar, so, looking at them in LESS, and then going to SASS, you're not gonna have a problem with old knowledge. In this regard, any frimetres may be studied in any way.LESS and SASS are close. Twitter Bootstrap officially moved from LESS to SASS from Given the popularity of the boutstrap, this decision will definitely play at the speed of SASS development compared to LESS.But I suggest you pay attention to Stylus. Since the Yandex team's development, the pre-processor has been growing at a very rapid pace, and it's far ahead of SASS. The opportunities already available in Stylus are confined to SASS only in the form of an open issue planned for an uncertain future. At best, at SASS, we'll see them in a year. Stylus can be used now.Besides, Stylus has a more flexible synthesis. You can write in CSS/SCSS with brackets, you can go back to SASS. You can drop the two-track in the sss-practice, you can assign variables through two-tracks like SASS, and even in peremptory languages.Speed: SASS and LESS at one level, Stylus 1.5 times faster. But SASS has a version of the pre-processor written on C - LibSass, it's very fast, 3.5 times faster than Stylus. It's only the PostCSS, but it's no longer a classic pre-processor. You can look at him and, by the way, you're developing in a good pace.

Simphony's a single leader.There's a million restrictions in it that just don't make it wrong. It's really pissing at first, but in time, you realize that the statutes are written in blood, and every restriction isn't the whistle of developers, it's the care of you.For example, the console team cannot have access to the counteraller method. And that's right, because if there's more to it than in one place, he doesn't belong in the counteraller, and he's supposed to be in the hillper library, and the controller's got to go to that helper.Laravel, in turn, is a very good Framworth, but it focuses on simplicity and speed of development by circumventing some important principles. To not be a voice, that's a good story. http://amdy.su/%D0%BD%D0%B5%D0%B4%D0%BE%D1%81%D1%82%D0%B0%D1%82%D0%BA%D0%B8-laravel/

♪ ParseWord You're talking. enumerator.Current without prior call enumerator.MoveNext - and, strictly speaking, the state enumerator.Current You have no definition of it. I mean. ParseWord Hope's someone in advance, to him, brought him in. enumerator I don't know.As a result of the discussion comments:You see the ISP principle as "several methods for a few." That's not exactly the correct interpretation. The essence of the ISP method in Enumerator-a.There's some kind of class that can do. Move forwardMoveNext)Repeat the current componentCurrent)To predict whether there is another element in sequence (HasNext)There are two categories of code(s) using this object:Clients A - they only need to move forward and read the current element.B-liners need to move forward, read the current element, and know if they can read the next. Thus, principle ISP states that the facility should provide two separate (segregated) interfaces.Interface A, which is provided to clients A - MoveNext + CurrentInterface B, which is provided to clients B - MoveNext + Current + HasNextIt's done to ensure that clients A don't depend on the interface they don't use. Defining the principle:Client should be forced to depend on methods it does not use.For your example, clients A who do not use HasNextshould not depend on the interface in which there is a method HasNext♪So, IEnumerator - it's an interface for category A clients. Standard interface for B clients, no. Accordingly, it is not implemented in standard enumerators.You wrote the B.'s client code client's class that only operates the category A interface. Of course it causes some. inconveniences♪ But this has nothing to do with the ISP violation - the problem is caused by the use of a specific class not by appointment. Any code using IEnumerableshall not make assumptions about the state of sequence. I mean, he should call first. MoveNextand then it's Current. In practice, it means you can't use the same element. Current A few methods - what does IEnumerable in a pure form, not applicable to a sausage.You're gonna have to do a lapse. IEnumerablewhich would clash the outcome of the last challenge MoveNext♪ That's what it's decided, for example. https://github.com/dotnet/roslyn/blob/faddd31a6bfc066861c2c45597dcb14484af49d4/src/Compilers/CSharp/Portable/Parser/Lexer.cs#L406 ♪It uses the rib. https://github.com/dotnet/roslyn/blob/56f605c41915317ccdb925f66974ee52282609e7/src/Compilers/CSharp/Portable/Parser/SlidingTextWindow.cs allowing, if necessary, a reversal:/// Keeps a sliding buffer over the SourceText of a file for the lexer.

The thing is, usually the cloning of an enumerator makes no sense.For example, if your data come from the network, there's no point in cloning the enumerator: you can't do the data twice without hanging them (and it's obviously a large and unjustifiable memory flow).If your sequence is obtained with a generator. yield returnYou can't incline the data. Worse still, the sequence in the rerun may change (e.g., if the data are issued depends on the outside world).The case where the sequence is known in advance, materialized and recorded is known. In this case, you have an interface. IList<T>where you can just remember the current index.If you know how long it takes to look forward, it's easy to write a screwdriver.class LookaheadEnumerable<T> : IEnumerable<T> { readonly IEnumerable<T> wrapped; readonly int maxLookaheadSize; public LookaheadEnumerable(IEnumerable&lt;T&gt; wrapped, int maxLookaheadSize) { this.wrapped = wrapped; this.maxLookaheadSize = maxLookaheadSize; } public LookaheadEnumerator&lt;T&gt; GetEnumerator() =&gt; new LookaheadEnumerator&lt;T&gt;(wrapped.GetEnumerator(), maxLookaheadSize); IEnumerator&lt;T&gt; IEnumerable&lt;T&gt;.GetEnumerator() =&gt; GetEnumerator(); IEnumerator IEnumerable.GetEnumerator() =&gt; GetEnumerator(); } class LookaheadEnumerator<T> : IEnumerator<T>, IEnumerator { List<T> lookaheadBuffer; readonly int maxLookaheadSize; readonly IEnumerator<T> wrapped; public LookaheadEnumerator(IEnumerator&lt;T&gt; wrapped, int maxLookaheadSize) { if (maxLookaheadSize &lt; 1) throw new ArgumentException("expect positive lookahead size"); this.maxLookaheadSize = maxLookaheadSize; this.wrapped = wrapped; } public T Current =&gt; lookaheadBuffer[0]; object IEnumerator.Current =&gt; Current; public void Dispose() =&gt; wrapped.Dispose(); public bool MoveNext() { if (lookaheadBuffer == null) lookaheadBuffer = new List&lt;T&gt;(maxLookaheadSize); else if (lookaheadBuffer.Count &gt; 0) lookaheadBuffer.RemoveAt(0); while (lookaheadBuffer.Count &lt; maxLookaheadSize) { if (!wrapped.MoveNext()) break; lookaheadBuffer.Add(wrapped.Current); } return lookaheadBuffer.Count &gt; 0; } public void Reset() { wrapped.Reset(); lookaheadBuffer = null; } public bool Lookahead(int idx, out T t) { bool good = idx &gt;= 0 &amp;&amp; idx &lt; lookaheadBuffer.Count; t = good ? lookaheadBuffer[idx] : default(T); return good; } } Example of use:var seq = new LookaheadEnumerable<int>(Enumerable.Range(0, 4), 7); using (var en = seq.GetEnumerator()) while (en.MoveNext()) { var value = en.Current; int lookehead; if (en.Lookahead(2, out lookehead)) Console.WriteLine($"value: {value}, lookahead + 2: {lookehead}"); else Console.WriteLine($"value: {value}, no lookahead"); }

MVM is just a design path, which means if you understand the pathterne, that is, you have a ready-to-mouth frimetre or not.Mostly, the need to use the Framuliers and libraries is based on the scope of the project, the tasks to be undertaken, the existing code base and the preferences of the Timbox. If the project is large and has not been used to support the development, most of your code base will be a frimetre.And now more important questions: How big a project? How many people are working on it? How well has your code been documented? How long will it take for a new developer to explore and start using it effectively? In the case of common frimetres, these issues are not as pressing as some form of documentation is usually available, sometimes producer support is available, there are sufficient solutions to typical issues in thematic forums, EnSO, and here.For a small project, there is no pressing need for heavy fireworks, and even a small project will win if it doesn't make any difference. In the case of a big project, it's not that clear.And, yes, it concerns not only the MVM you mentioned, but all other areas, whether WEB, database work, etc.

You don't have a database, probably a problem with the data source line (DSN) in the first argument of the method. setupR::setup('mysql:host=localhost;dbname = name','root','password'); Try to remove the gaps before and after the name of the database. nameR::setup('mysql:host=localhost;dbname=name','root','password'); Make sure your database is really called nameand not otherwise.
