While OCaml programming is statically type-checked, uses of the < tt > Marshal </ tt > module may break type guarantees, as there is no way to check whether an unmarshalled stream represents objects of the expected type.

This is the case with Lisp and OCaml.

This is the definition used when working with a language like OCaml.

It is a variant of ML and is largely compatible with the OCaml implementation.

It is written in OCaml, with some C and even some assembly.

For example, the following OCaml code defines a polymorphic identity function that has a universally quantified type, which is printed by the interpreter on the 2nd line:

In OCaml, only single assignment is allowed for variables, via the syntax ; however destructive update can be used on elements of arrays and strings with separate < code ><-</ code > operator, as well as on fields of records and objects that have been explicitly declared mutable ( meaning capable of being changed after their initial declaration ) by the programmer.

GODI is a package management system for the OCaml programming language.

* MLDonkey ( Cross Platform ), written in OCaml, under the GPL, however as of version 2. 9. 0, support is officially unmaintained and disabled in the binaries.

The basic interface is for C but wrappers exist for other languages including Ada, C ++, C #, OCaml, Perl, PHP, and Python.

The D and OCaml languages have run time bounds checking that is enabled or disabled with a compiler switch.

An additional complication arises in languages such as OCaml that support both optional named parameters and partial application: it is impossible in general to distinguish between a partially applied function and a function to which a subset of parameters have been provided.

OCaml resolves this ambiguity by requiring a positional parameter to follow all optional named parameters: its presence or absence is used to decide whether the function has been fully or partially applied.

SWIG ( Simplified Wrapper and Interface Generator ) is an open source software tool used to connect computer programs or libraries written in C or C ++ with scripting languages such as Lua, Perl, PHP, Python, R, Ruby, Tcl, and other languages like C #, Java, Go, Modula-3, OCaml, Octave, and Scheme.

Coq is implemented in OCaml.

The term is used at least in Haskell, Clean, Erlang, occam, Promela, OCaml and Scala programming languages.

It is intended to be used on Unix-like operating systems and is a bit difficult to install, as it needs several non-standard OCaml modules.

Camlp4 stands for Caml Preprocessor and Pretty-Printer and one of its most important applications is the definition of domain-specific extensions of the syntax of OCaml.

Camlp4 is part of the official OCaml distribution which is developed at the INRIA.

The abstract syntax tree is at the center of the syntax extensions, which are in fact OCaml programs.

In OCaml, the library function Oo. copy performs shallow copying of an object.

ML eventually developed into several dialects, the most common of which are now OCaml and Standard ML.

OCaml chooses the last matching definition of a class inheritance list to resolve which method implementation to use under ambiguities.

Programming languages which have been self-hosted include Ada, BASIC, C, CoffeeScript, F #, FASM, Forth, Haskell, Java, Lisp, Modula-2, OCaml, Oberon, Pascal, Python, Scala, Smalltalk, and Vala.

Written in the OCaml programming language and licensed under the GPL, the application separates the user interface ( which can be a web browser, telnet, or a third-party GUI application ) and the code that interacts with the peer-to-peer networks.

Although the definition of grammars must be done in OCaml, the parser that is being defined or extended is not necessarily related to OCaml, in which case the syntax tree that is being manipulated is not the one of OCaml.

Several libraries are provided which facilitate the specific manipulation of OCaml syntax trees.

The only thing that the developer has to do is write a Camlp4 grammar which converts the domain-specific language in question into a regular OCaml program.

If the target language is OCaml, simple syntax add-ons or syntactic sugar can be defined, in order to provide an expressivity which is not easy to achieve using the standard features of the OCaml language.

A syntax extension is defined by a compiled OCaml module, which is passed to the camlp4o executable along with the program to process.

Currently, the main implementation of Caml is OCaml, which adds many new features to the language including an object layer.

This preprocessor takes the description of the semantics of a language ( i. e. an interpreter ) and, by combining compile-time interpretation and code generation, turns that definition into a compiler to the OCaml programming language — and from that language, either to bytecode or to native code.

It can be output in a binary form, e. g. it can be passed directly to one of the OCaml compilers, or it can be converted back into a clear text program.

However, prominent functional programming languages such as Common Lisp, Scheme, ISLISP, Clojure, Racket, Erlang, OCaml, Haskell, Scala and F # have been used in industrial and commercial applications by a wide variety of organizations.

* In OCaml, parent classes are specified individually in the body of the class definition.

The other most widely-used ML dialect, OCaml, differs in various insubstantial ways.

* ocamlyacc a Yacc version for OCaml.

Similarly, a number of programs written in OCaml customize the syntax of the language by the addition of new operators.

Similarly, statically checked, type-safe regular expressions or code generation may be added to the syntax and semantics of OCaml through macros, as well as micro-threads ( also known as coroutines or fibers ), monads or transparent XML manipulation.
