Lasso (programming Language)
Lasso is an application server and server management interface designed to develop internet applications. It is also a general-purpose, high-level programming language. Originally a web datasource connection tool for Filemaker and later included in Apple Computer's FileMaker 4.0 and Claris Homepage as CDML, it has since evolved into a complex language used to develop and serve large-scale internet applications and web pages. Lasso includes a simple template system allowing code to control generation of HTML and other content types. Lasso is an object-oriented programming language in which every value is an object. It also supports procedural programming through ''unbound'' methods. The language uses traits and multiple dispatch extensively. Lasso has a dynamic type system, where objects can be loaded and augmented at runtime, automatic memory management, a comprehensive standard library, and three compiling methodologies: dynamic (comparable to PHP- Python), just-in-time com ...

Type System
In computer programming, a type system is a logical system comprising a set of rules that assigns a property called a ''type'' (for example, integer, floating point, string) to every '' term'' (a word, phrase, or other set of symbols). Usually the terms are various language constructs of a computer program, such as variables, expressions, functions, or modules. A type system dictates the operations that can be performed on a term. For variables, the type system determines the allowed values of that term. Type systems formalize and enforce the otherwise implicit categories the programmer uses for algebraic data types, data structures, or other data types, such as "string", "array of float", "function returning boolean". Type systems are often specified as part of programming languages and built into interpreters and compilers, although the type system of a language can be extended by optional tools that perform added checks using the language's original type synta ...

Procedural Programming
Procedural programming is a programming paradigm, classified as imperative programming, that involves implementing the behavior of a computer program as Function (computer programming), procedures (a.k.a. functions, subroutines) that call each other. The resulting program is a series of steps that forms a hierarchy of calls to its constituent procedures. The first major procedural programming languages appeared –1964, including Fortran, ALGOL, COBOL, PL/I and BASIC. Pascal (programming language), Pascal and C (programming language), C were published –1972. Computer processors provide hardware support for procedural programming through a stack register and instructions for Subroutine#Jump to subroutine, calling procedures and returning from them. Hardware support for other types of programming is possible, like Lisp machines or Java processors, but no attempt was commercially successful. Development practices Certain software development practices are often employed with ...

Object-oriented
Object-oriented programming (OOP) is a programming paradigm based on the concept of '' objects''. Objects can contain data (called fields, attributes or properties) and have actions they can perform (called procedures or methods and implemented in code). In OOP, computer programs are designed by making them out of objects that interact with one another. Many of the most widely used programming languages (such as C++, Java, and Python) support object-oriented programming to a greater or lesser degree, typically as part of multiple paradigms in combination with others such as imperative programming and declarative programming. Significant object-oriented languages include Ada, ActionScript, C++, Common Lisp, C#, Dart, Eiffel, Fortran 2003, Haxe, Java, JavaScript, Kotlin, Logo, MATLAB, Objective-C, Object Pascal, Perl, PHP, Python, R, Raku, Ruby, Scala, SIMSCRIPT, Simula, Smalltalk, Swift, Vala and Visual Basic.NET. History The idea of "objects" in programm ...

Internet Media Type
In information and communications technology, a media type, content type or MIME type is a two-part identifier for file formats and content formats. Their purpose is comparable to filename extensions and uniform type identifiers, in that they identify the intended data format. They are mainly used by technologies underpinning the Internet, and also used on Linux desktop systems. The Internet Assigned Numbers Authority, Internet Assigned Numbers Authority (IANA) is the official authority for the standardization and publication of these classifications. Media types were originally defined in Request for Comments (MIME) Part One: Format of Internet Message Bodies (Nov 1996) in November 1996 as a part of the ''MIME (Multipurpose Internet Mail Extensions)'' specification, for denoting type of email message content and attachments; hence the original name, ''MIME type''. Media types are also used by other internet protocols such as HTTP, document file formats such as HTML element, HTML, ...

HTML
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript, a programming language. Web browsers receive HTML documents from a web server or from local storage and browser engine, render the documents into multimedia web pages. HTML describes the structure of a web page Semantic Web, semantically and originally included cues for its appearance. HTML elements are the building blocks of HTML pages. With HTML constructs, HTML element#Images and objects, images and other objects such as Fieldset, interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, Hyperlink, links, quotes, and other items. HTML elements are delineated ...

Claris Homepage
Claris Home Page was one of the earliest true WYSIWYG HTML editors, developed from 1994 on. The project was code-named Loma Prieta. Claris purchased it from San Andreas Systems, reworked it to use the user interface common to all their products, and released it in 1996. History Home Page supported all the features common in HTML at the time. In January 1998, the third and final version of Home Page was released. This version contained templates and tools for building database-driven websites using FileMaker Pro 4.1 and Claris Dynamic Markup Language ( CDML). Within weeks of the final Home Page release, parent company Apple Computer reorganized Claris into FileMaker Inc., with Home Page and the FileMaker database as its only remaining products. Home Page was discontinued in 2001, though it continued to run in the Classic Environment of Mac OS X through version 10.4. The Home Page was designed for HTML 3.2, and consequently does not suppor t HTML 4.0. Home Page cannot display Po ...

High-level Programming Language
A high-level programming language is a programming language with strong Abstraction (computer science), abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language ''elements'', be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program simpler and more understandable than when using a lower-level language. The amount of abstraction provided defines how "high-level" a programming language is. In the 1960s, a high-level programming language using a compiler was commonly called an ''autocode''. Examples of autocodes are COBOL and Fortran. The first high-level programming language designed for computers was Plankalkül, created by Konrad Zuse. However, it was not implemented in his time, and his original contributions were largely isolated from other developments due to World War II, aside from the language's influe ...

General-purpose Programming Language
In computer software, a general-purpose programming language (GPL) is a programming language for building software in a wide variety of application Domain (software engineering), domains. Conversely, a Domain-specific language, domain-specific programming language (DSL) is used within a specific area. For example, Python (programming language), Python is a GPL, while SQL is a DSL for Query language, querying relational databases. History Early programming languages were designed for scientific computing (numerical calculations) or commercial data processing, as was computer hardware. Scientific languages such as Fortran and ALGOL, Algol supported floating-point calculations and multidimensional arrays, while business languages such as COBOL supported fixed-field file formats and record (computer science), data records. Much less widely used were specialized languages such as IPL-V and LISP for List (abstract data type), symbolic list processing; COMIT for string manipulation; APT ...

Application Server
An application server is a server that hosts applications or software that delivers a business application through a communication protocol. For a typical web application, the application server sits behind the web servers. An application server framework is a service layer model. It includes software components available to a software developer through an application programming interface. An application server may have features such as clustering, fail-over, and load-balancing. The goal is for developers to focus on the business logic. Java application servers Jakarta EE (formerly Java EE or J2EE) defines the core set of API and features of Java application servers. The Jakarta EE infrastructure is partitioned into logical containers. *EJB container: Enterprise Beans are used to manage transactions. According to the Java BluePrints, the business logic of an application resides in Enterprise Beans—a modular server component providing many features, including dec ...

Reflection (computer Programming)
In computer science, reflective programming or reflection is the ability of a process to examine, introspect, and modify its own structure and behavior. Historical background The earliest computers were programmed in their native assembly languages, which were inherently reflective, as these original architectures could be programmed by defining instructions as data and using self-modifying code. As the bulk of programming moved to higher-level compiled languages such as ALGOL, COBOL, Fortran, Pascal, and C, this reflective ability largely disappeared until new programming languages with reflection built into their type systems appeared. Brian Cantwell Smith's 1982 doctoral dissertation introduced the notion of computational reflection in procedural programming languages and the notion of the meta-circular interpreter as a component of 3-Lisp. Uses Reflection helps programmers make generic software libraries to display data, process different formats of data, perform s ...
