Editing Automatic programming

{{short description|Type of computer programming}}

In [[computer science]], '''automatic programming'''<ref>Ricardo Aler Mur, "[http://www.evannai.inf.uc3m.es/et/icml06/aiptutorial.htm Automatic Inductive Programming] {{Webarchive|url=https://web.archive.org/web/20160304073124/http://www.evannai.inf.uc3m.es/et/icml06/aiptutorial.htm |date=2016-03-04 }}", ''ICML 2006 Tutorial''. June 2006.</ref> is a type of [[computer programming]] in which some mechanism generates a [[computer program]], to allow human [[programmer]]s to write the code at a higher abstraction level.

There has been little agreement on the precise definition of automatic programming, mostly because its meaning has changed over time. [[David Parnas]], tracing the history of "automatic programming" in published research, noted that in the 1940s it described automation of the manual process of punching [[paper tape]]. Later it referred to translation of [[high-level programming language]]s like [[Fortran]] and [[ALGOL]]. In fact, one of the earliest programs identifiable as a [[compiler]] was called [[Autocode]]. [[David Parnas|Parnas]] concluded that "automatic programming has always been a [[euphemism]] for programming in a higher-level language than was then available to the programmer."<ref>D. L. Parnas. "[https://web.stanford.edu/class/cs99r/readings/parnas1.pdf Software Aspects of Strategic Defense Systems]." ''American Scientist''. November 1985.</ref>

[[Program synthesis]] is one type of automatic programming where a procedure is created from scratch, based on mathematical requirements.

==Origin==
[[Milly Koss|Mildred Koss]], an early [[UNIVAC]] programmer, explains: "Writing machine code involved several tedious steps—breaking down a process into discrete instructions, assigning specific memory locations to all the commands, and managing the I/O buffers. After following these steps to implement mathematical routines, a sub-routine library, and sorting programs, our task was to look at the larger programming process. We needed to understand how we might reuse tested code and have the machine help in programming. As we programmed, we examined the process and tried to think of ways to abstract these steps to incorporate them into higher-level language. This led to the development of interpreters, assemblers, compilers, and generators—programs designed to operate on or produce other programs, that is, ''automatic programming''."<ref>Chun, Wendy.

==Generative programming==
'''Generative programming''' and the related term [[Metaprogramming|meta-programming]]<ref>{{cite web

|url=http://www.sigplan.org/Conferences/GPCE}}</ref><ref>A conference of [[SIGPLAN]] on
this topic is planned for November 2018. Earlier/1970s attempts in this area included [[Yacc]]
and the related Lex programs.</ref>

The goal is to improve [[programmer]] productivity.<ref>James Wilcox, "[http://edgewatertech.wordpress.com/2011/03/11/paying-too-much-for-custom-application-implementation-code-generation/ Paying Too Much for Custom Application Development]", March 2011.</ref> It is often related to code-reuse topics such as [[component-based software engineering]].

==Source-code generation==
''Source-code generation'' is the process of generating source code based on a description of the problem<ref>{{cite web
|quote=Software that generates application programs from descriptions of the problem rather than by traditional programming. It is at a higher level and easier to use than a high-level programming language such as ...
|url=https://www.pcmag.com/encyclopedia/term/37909/application-generator
|title=Application generator |publisher=PCmag.com}}</ref> or an [[ontology (information science)|ontological]] model such as a template and is accomplished with a [[programming tool]] such as a [[template processor]] or an [[integrated development environment]] (IDE). These tools allow the generation of [[source code]] through any of various means.

Modern programming languages are well supported by tools like [https://www.json4swift.com/ Json4Swift] ([[Swift (programming language)|Swift]]) and [https://www.json2kotlin.com/ Json2Kotlin] ([[Kotlin (programming language)|Kotlin]]).

Programs that could generate [[COBOL]] code include: 
* the DYL250/DYL260/DYL270/DYL280 series<ref>{{cite web

* [[Business Controls Corporation]]'s SB-5
* [[KPMG|Peat Marwick Mitchell]]'s PMM2170 application-program-generator package
These application generators supported COBOL inserts and overrides.

A [[Macro (computer science)|macro]] processor, such as the [[C preprocessor]], which replaces patterns in source code according to relatively simple rules, is a simple form of source-code generator. [[Source-to-source compiler|Source-to-source]] code generation tools also exist.<ref>Noaje, Gabriel, Christophe Jaillet, and Michaël Krajecki.

[[Large language model]]s such as [[ChatGPT]] are capable of generating a program's source code from a description of the program given in a natural language.<ref name="ChatGPT can write code">{{Cite web |url=https://www.zdnet.com/article/chatgpt-can-write-code-now-researchers-say-its-good-at-fixing-bugs-too/ |title=ChatGPT can write code.

Many [[Relational database system|relational database systems]] provide a function that will export the content of the database as [[SQL]] [[Data definition language|data definition]] queries, which may then be executed to re-import the tables and their data, or migrate them to another RDBMS.

==Low-code applications==
{{Main article|Low-code development platforms}}

A [[Low-code development platforms|low-code development platform]] (LCDP) is software that provides an environment [[programmer]]s use to create [[application software]] through [[graphical user interface]]s and configuration instead of traditional [[computer programming]].
