A metaprogram is a program that manipulates other programs (or itself) as its data. The canonical example is a compiler.
The basic problem is that any general-purpose programming language without a metaprogramming model that is designed to be as pleasant and expressive as the language itself will eventually frustrate the user with it's limitations. No-one can design the perfect language, and yet allowing users to extend the language in generic ways is avoided with a BondageAndDiscipline mentality
CURL is a tool to transfer data from or to a server using one of the protocols (DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMTP, SMTPS, TELNET and TFTP) . CURL command is designed to work without user interaction. curl offers a busload of useful tricks like proxy support, user authentication, FTP upload, HTTP post, SSL connections, cookies, file transfer resume, Metalink, and more. As you will see below, the number of features will make your head spin! CURL indicates the amount of transferred data during operation.
Forth is a computer language originally designed for embedded and real time applications. Forth is a structured, imperative, reflexive, extensible, stack based computer programming language and programming environment. Forth is not an assembler, it is a high-level language (although most versions also include an assembler for the target processor). However, it does not really resemble most other high-level programming language. A procedural programming language without type checking, Forth features both interactive execution of commands (making it suitable as a shell for systems that lack a more formal operating system) and the ability to compile sequences of commands for later execution. Forth has enough support to keep several language vendors and contractors in business. Forth is currently used in boot loaders boot loaders such as Open Firmware, space applications, and other embedded systems
Lisp is a family of computer programming languages used for the Artificial intelligence and mathematical applications. Lisp the second oldest high-level programming language that introduce the many new features to the programming e.g tree data structures, management, dynamic, and the self-hosting compiler. Linked Lists are the main data type of the lisp programming language on the name of the “list processing” the name LISP is derived. Lisp programming language provide the feature of interchangeability of the code and data to provide the instant recognizable syntax. It quickly became the favored programming language for artificial intelligence (AI) research. Lisp has spawned many variations on the core theme of an S-expression language. Moreover, each given dialect may have several implementations—for instance, there are more than a dozen implementations of Common Lisp
Maude is a high-performance reflective language and system supporting both equational and rewriting logic specification and programming for a wide range of applications. Maude has been influenced in important ways by the OBJ3 language, which can be regarded as an equational logic sublanguage. Besides supporting equational specification and programming, Maude also supports rewriting logic computation. Maude supports in a systematic and efficient way logical reflection. This makes Maude remarkably extensible and powerful, supports an extensible algebra of module composition operations, and allows many advanced meta-programming and metalanguage applications
Poplog is a logic based programming language and it is multi-language programming environment for the programming languages POP-11, Common Lisp, Prolog and standard ML. It was developed in UK for teaching and research in artifical intelligence at the University of Sussex. It is free Cross-platform Compiler
Roop is a multiparadigm programming language which is target the artificial intelligence applications. Roop Programming language is developed in the china at the Chengdu University of China. Roop programming language is easy to learn and flexible programming language as compare to other artificial intelligence programming languages. It combines the rule-based, procedural, logical and object-oriented programming languages. Roop Programming language can be used in many parts of the artificial intelligence :
