/** \defgroup CINDEX libclang: C Interface to Clang
|
|
*
|
|
* The C Interface to Clang provides a relatively small API that exposes
|
|
* facilities for parsing source code into an abstract syntax tree (AST),
|
|
* loading already-parsed ASTs, traversing the AST, associating
|
|
* physical source locations with elements within the AST, and other
|
|
* facilities that support Clang-based development tools.
|
|
*
|
|
* This C interface to Clang will never provide all of the information
|
|
* representation stored in Clang's C++ AST, nor should it: the intent is to
|
|
* maintain an API that is relatively stable from one release to the next,
|
|
* providing only the basic functionality needed to support development tools.
|
|
*
|
|
* To avoid namespace pollution, data types are prefixed with "CX" and
|
|
* functions are prefixed with "clang_".

|
* method.
|
|
*
|
|
* In both Objective-C and C++, a method (aka virtual member function,
|
|
* in C++) can override a virtual method in a base class. For
|
|
* Objective-C, a method is said to override any method in the class's
|
|
* interface (if we're coming from an implementation), its protocols,
|
|
* or its categories, that has the same selector and is of the same
|
|
* kind (class or instance). If no such method exists, the search
|
|
* continues to the class's superclass, its protocols, and its
|
|
* categories, and so on.
|
|
*
|
|
* For C++, a virtual member function overrides any virtual member
|
|
* function with the same signature that occurs in its base
|
|
* classes. With multiple inheritance, a virtual member function can
|
|
* override several virtual member functions coming from different
|
|
* base classes.
|
|
*
|
|
* In all cases, this function determines the immediate overridden
|
|
* method, rather than all of the overridden methods. For example, if
|
|
* a method is originally declared in a class A, then overridden in B
|
|
* (which in inherits from A) and also in C (which inherited from B),
|
|
* then the only overridden method returned from this function when
|
|
* invoked on C's method will be B's method. The client may then
|
|
* invoke this function again, given the previously-found overridden
|

* methods, to map out the complete method-override set.

* \brief Perform code completion at a given location in a translation unit.
|
|
*
|
|
* This function performs code completion at a particular file, line, and
|
|
* column within source code, providing results that suggest potential
|
|
* code snippets based on the context of the completion. The basic model
|
|
* for code completion is that Clang will parse a complete source file,
|
|
* performing syntax checking up to the location where code-completion has
|
|
* been requested. At that point, a special code-completion token is passed
|
|
* to the parser, which recognizes this token and determines, based on the
|
|
* current location in the C/Objective-C/C++ grammar and the state of
|
|
* semantic analysis, what completions to provide. These completions are
|
|
* returned via a new \c CXCodeCompleteResults structure.
|
|
*
|
|
* Code completion itself is meant to be triggered by the client when the
|
|
* user types punctuation characters or whitespace, at which point the
|
|
* code-completion location will coincide with the cursor. For example, if \c p
|
|
* is a pointer, code-completion might be triggered after the "-" and then
|
|
* after the ">" in \c p->. When the code-completion location is afer the ">",
|
|
* the completion results will provide, e.g., the members of the struct that
|
|
* "p" points to. The client is responsible for placing the cursor at the
|
|
* beginning of the token currently being typed, then filtering the results
|
|
* based on the contents of the token. For example, when code-completing for
|
|
* the expression \c p->get, the client should provide the location just after
|
|
* the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
|
|
* client can filter the results based on the current token text ("get"), only
|
|
* showing those results that start with "get". The intent of this interface
|
|
* is to separate the relatively high-latency acquisition of code-completion
|
|
* results from the filtering of results on a per-character basis, which must
|
|
* have a lower latency.
|
|
*
|
|
* \param TU The translation unit in which code-completion should
|
|
* occur. The source files for this translation unit need not be
|
|
* completely up-to-date (and the contents of those source files may
|
|
* be overridden via \p unsaved_files). Cursors referring into the
|
|
* translation unit may be invalidated by this invocation.
|
|
*
|
|
* \param complete_filename The name of the source file where code
|
|
* completion should be performed. This filename may be any file
|
|
* included in the translation unit.
|
|
*
|
|
* \param complete_line The line at which code-completion should occur.
|
|
*
|
|
* \param complete_column The column at which code-completion should occur.
|
|
* Note that the column should point just after the syntactic construct that
|
|
* initiated code completion, and not in the middle of a lexical token.
|
|
*
|
|
* \param unsaved_files the Tiles that have not yet been saved to disk
|
|
* but may be required for parsing or code completion, including the
|
|
* contents of those files. The contents and name of these files (as
|
|
* specified by CXUnsavedFile) are copied when necessary, so the
|
|
* client only needs to guarantee their validity until the call to
|
|
* this function returns.
|
|
*
|
|
* \param num_unsaved_files The number of unsaved file entries in \p
|
|
* unsaved_files.
|
|
*
|
|
* \param options Extra options that control the behavior of code
|
|
* completion, expressed as a bitwise OR of the enumerators of the
|
|
* CXCodeComplete_Flags enumeration. The
|
|
* \c clang_defaultCodeCompleteOptions() function returns a default set
|
|
* of code-completion options.
