The most common example of this is the C preprocessor, which takes lines beginning with '#' as directives.

Macros in the PL / I language are written in a subset of PL / I itself: the compiler executes " preprocessor statements " at compilation time, and the output of this execution forms part of the code that is compiled.

Due to the nature of the contest, entries often employ strange or unusual tricks, such as using the C preprocessor to do things it was not designed to do, or avoiding commonly-used constructs in the C programming language in favor of much more obscure ways of achieving the same thing.

The preprocessor did not understand all of the language and much of the code was written via translations.

Some other languages rely on a fully external language to define the transformations, such as the XSLT preprocessor for XML, or its statically typed counterpart CDuce.

The MetaOCaml preprocessor / language provides similar features for external Domain-Specific Programming Languages.

The language of preprocessor directives is agnostic to the grammar of C, so the C preprocessor can also be used independently to process other kinds of text files.

Generally polyglots are written in a combination of C ( which allows redefinition of tokens with a preprocessor ) and a scripting language such as Lisp, Perl or sh.

Embedded SQL is a technique that simplifies the development of C / C ++ and COBOL Firebird applications, by using a preprocessor called gpre, which allows to embed SQL statements directly into the source code of the host language.

* C preprocessor, a program that processes the C programming language before it is compiled

GAS uses assembler directives ( also known as pseudo ops ), which are keywords beginning with a period that behave similarly to preprocessor directives in the C programming language.

In C and C ++, the language supports a simple macro preprocessor.

The preprocessor also has access to symbol information and compiler settings, such as the language dialect.

He also wrote the Portable I / O Library ( the predecessor to stdio. h in C ) and contributed significantly to the development of the C language preprocessor.

During 1971 and 1972 B evolved into " New B " and then C, with the preprocessor being added in 1972 and early 1973 at the urging of Alan Snyder.

C ++ started as a preprocessor for C and is currently nearly a superset of C.

* A preprocessor performs macro definition, source code file inclusion, and conditional compilation.

It is now possible ( and relatively easy ) to write an entirely portable program in Fortran, even without recourse to a preprocessor.

Many Fortran compilers have integrated subsets of the C preprocessor into their systems.

SIMSCRIPT is an application specific Fortran preprocessor for modeling and simulating large discrete systems.

The preprocessor also provides an ability to write out the content of the macros and to add to already created macros in any place in the text of the literate program source file, thereby disposing of the need to keep in mind the restrictions imposed by traditional programming languages or to interrupt the flow of thought.

C preprocessor macros work by simple textual search-and-replace at the token, rather than the character, level.

Meanwhile, macro systems, such as the C preprocessor described earlier, that work at the level of lexical tokens cannot preserve the lexical structure reliably.

REBOL / SDK, providing a choice of kernels to bind against, as well as a preprocessor, was released in December 2002.

Typically, each preprocessor translates only sections of the input file that are specially marked, passing the rest of the file through unchanged.

* eqn preprocessor allows mathematical formulae to be specified in simple and intuitive manner.

* tbl is a preprocessor for formatting tables.

Winning entries are awarded with a category, such as " Worst Abuse of the C preprocessor " or " Most Erratic Behavior ", and then announced on the official IOCCC website.

* C and C ++, via the DBC for C preprocessor, GNU Nana, eCv static analysis tool, or the Digital Mars C ++ compiler, via CTESK extension of C. Loki Library provides a mechanism named ContractChecker that verifies a class follows design by contract.

* Java, via iContract2, Contract4J, jContractor, Jcontract, C4J, Google CodePro Analytix, STclass, Jass preprocessor, OVal with AspectJ, Java Modeling Language ( JML ), Jtest, SpringContracts for the Spring framework, Modern Jass, Custos using AspectJ, JavaDbC using AspectJ, JavaTESK using extension of Java, chex4j using javassist, or Contracts for Java, and the highly customizable java-on-contracts.

GNU m4 is an implementation of the m4 macro preprocessor.

ScriptBasic also has an open interface for preprocessor developers.

Currently there is a single preprocessor that delivers debugger functionality.

Slides in HTML format with English narration in RealAudio format are also available to get a jump start learning the architecture and module, preprocessor and embedding developments.

In computer science, a preprocessor is a program that processes its input data to produce output that is used as input to another program.

The program elements associated with attributes are transformed to more detailed programs by a supporting tool ( e. g. preprocessor ).

dBase features an IDE with a Command Window and Navigator, a just in time compiler, a preprocessor, a virtual machine interpreter, a linker for creating dBase application. exe's, a freely available runtime engine, and numerous two-way GUI design tools including a Form Designer, Report Designer, Menu Designer, Label Designer, Datamodule Designer, SQL Query Designer, and Table Designer.

One way to handle this is write conditional code, with code blocks selected by means of preprocessor directives (); but because of the wide variety of build environments this approach quickly becomes unmanageable.

Because of this, MediaWiki, for example, has had to introduce its own < code >< nowiki ></ nowiki ></ code > tag for citing references in notes, an idea which has since also been implemented for generic use by the Nelson HTML preprocessor.

The C preprocessor replaces all occurrences of the following nine trigraph sequences by their single-character equivalents before any other processing.

REP is an alternative implementation of RZIP algorithm by Bulat Ziganshin used in his FreeArc archiver as preprocessor for LZMA / Tornado compression algorithms.

Source lines that should be handled by the preprocessor, such as and are referred to as preprocessor directives.

An independent compatible implementation of the eqn preprocessor has been developed by GNU as part of groff, the GNU version of troff.

The preprocessor is used to locate two types of empty space in the map, the empty space enclosed by brushes where the game will be played, and the other empty space outside the brushes that the player will never see.

A Camlp4 preprocessor operates by loading a collection of compiled modules which define a parser as well as a pretty-printer: the parser converts an input program into an internal representation.
