Conventional programming languages ​​are difficult to learn and use, requiring skills that many people do not have. For this reason, user interfaces from a wide range of programs have begun to come with facilities that complement and facilitate programming capabilities.

Visual programming is programming in which more than one size is used to convey information.

Examples of such additional dimensions are the use of multidimensional objects, the use of spatial relations, or the use of the time dimension to specify the “before-after” type semantic relationships. Each multidimensional or relationship is a token, as in traditional text programming languages… read more +

GNU Flex

At the conceptual level, the compiler is a program that translates from one language to another.

Most often, the compiler translates from a high-level language (C, C ++, Java), which is written and understood by a programmer, into a low-level language (bytecode, assembly language, machine code) that can be more than executed by the processor. The lexical analysis is the first step in the compiler’s understanding of the source files.

Flex is a generator of lexical analyzers.

It receives at the input a file that contains a specification of the atoms to be recognized by the… read more +

DOS (Disk Operating System) is a single-tasking, single-user command-line operating system.

Microsoft created the original version in 1981 for IBM and was called PC-DOS. Microsoft then ported and sold the system to IBM-PC compatible computers manufactured by others than IBM under the name of the Microsoft Disk Operating System (MS-DOS).

This version was the most popular OS at the time. In addition to the original versions of Microsoft/IBM code, there are other versions of DOS, more or less compatible with MS-DOS/PC-DOS such as DR-DOS and FreeDOS. This was possible due to the simplicity of the system… read more +

ALGOL which is short for ALGOrithmic Language is a programming language suitable for writing algorithms.

It was made in 1959, but the most widespread version is ALGOL-60, which was adopted at an international conference in Paris and was perfected by specialists from the International Federation for Information Processing (IFIP).

ALGOL was used on large numerical computers. the SUBSETALGOL-60 version has been developed for small numerical computers.

AutoIt

AutoIt is a free scripting and automation language for the Microsoft Windows operating system. Initially, it was created exclusively for the automation of various tasks in the running programs, but it has… read more +

The APL named after the book A Programming Language is an interactive board-oriented language and development environment that is available from commercial and non-commercial providers for most platforms.

It is based on a mathematical notation invented by Kenneth E. Iverson.

The unique combination of unique or unusual features of APL language ranks it among the most productive programming languages:

1. It is concise, using symbols instead of words and applying functions to the whole picture without using explicit loops.

2. It is solution-oriented; with an emphasis on expressing algorithms independent of the machine architecture or operating system.

BRAINFUCK

Brainfuck is an esoteric programming language, known for its simplicity. The programmer Urban Müller created this programming language, only to be tested with no practical application. Popular forms of censorship are brainf***, brainf*ck, brainfsck, b****fuck, or BF. The name of the language is not generally written in upper case, except when it is at the beginning of the sentence, although it is a proper noun.

Urban Müller, inspired by the FALSE language compiler, which was 1024 bits long, created brainfuck in 1993 with the intention of making a programming language that could be implemented with the… read more +

BASIC

BASIC (an acronym for English Beginners All-purpose Symbolic Instruction Code) is a high-level computer programming language, very similar to English, making it easy to remember and ideal for beginners.

Thus, the generation of users that were the predecessors of the PC era took the first contact with programming through HC computers, which were based on a version of BASIC.

It’s a simple language to learn, created in 1964 by John G. Kemeny and Thomas E. Kurtz at Dartmouth College.

One of the best editors, compilers, and debuggers for beginners in this language is QBASIC (an acronym for… read more +

Cayenne is a functionally dependent programming language, created by Lennart Augustsson in 1998, making it one of the oldest dependent programming language. An important design decision is that the language allows unrestricted recursive functions to be used at the type level, making the type of verification undecided. There are very few building blocks in the language. The basic types are functions, products, and sums. Features and products use dependent types to gain additional power.

The syntax is largely borrowed from Haskell. There is no special system of modules because, with the types of registrations (products), they are… read more +

Curry is an experimental functional logic programming language based on Haskell language. It combines the elements of functional and logical programming, including the integration of constraint programming. It is almost a superset of Haskell, lacking support, especially for overloading using type classes, which some implementations provide anyway as an extension of language, such as the Münster rainbow compiler.

Due to the absence of side effects, a functional logic program can be executed with different strategies. In order to evaluate expressions, Curry uses a variant of the narrowing strategy needed, which combines lazy evaluation with undetermined search strategies…. read more +

Epigram is a functional programming language with dependent types. The epigram also refers to the IDE, usually packaged with the language. The Epigram type system is powerful enough to express the program specifications. Its purpose is to support a smooth transition from regular programs to integrated programs and evidence whose correctness can be verified and certified by the compiler. Epigram exploits the proposition as a type principle and is based on intuition type theory.

The Epigram prototype was implemented by Conor McBride based on the collaboration with James McKinna. Its development is continued by the Epigram… read more +
