Functions

CINDEX_LINKAGE
CXCompilationDatabase 
clang_CompilationDatabase_fromDirectory (const char *BuildDir, CXCompilationDatabase_Error *ErrorCode)
 Creates a compilation database from the database found in directory buildDir. For example, CMake can output a compile_commands.json which can be used to build the database.
CINDEX_LINKAGE void clang_CompilationDatabase_dispose (CXCompilationDatabase)
 Free the given compilation database.
CINDEX_LINKAGE CXCompileCommands clang_CompilationDatabase_getCompileCommands (CXCompilationDatabase, const char *CompleteFileName)
 Find the compile commands used for a file. The compile commands must be freed by clang_CompileCommands_dispose.
CINDEX_LINKAGE CXCompileCommands clang_CompilationDatabase_getAllCompileCommands (CXCompilationDatabase)
 Get all the compile commands in the given compilation database.
CINDEX_LINKAGE void clang_CompileCommands_dispose (CXCompileCommands)
 Free the given CompileCommands.
CINDEX_LINKAGE unsigned clang_CompileCommands_getSize (CXCompileCommands)
 Get the number of CompileCommand we have for a file.
CINDEX_LINKAGE CXCompileCommand clang_CompileCommands_getCommand (CXCompileCommands, unsigned I)
 Get the I'th CompileCommand for a file.
CINDEX_LINKAGE CXString clang_CompileCommand_getDirectory (CXCompileCommand)
 Get the working directory where the CompileCommand was executed from.
CINDEX_LINKAGE unsigned clang_CompileCommand_getNumArgs (CXCompileCommand)
 Get the number of arguments in the compiler invocation.
CINDEX_LINKAGE CXString clang_CompileCommand_getArg (CXCompileCommand, unsigned I)
 Get the I'th argument value in the compiler invocations.
CINDEX_LINKAGE unsigned clang_CompileCommand_getNumMappedSources (CXCompileCommand)
 Get the number of source mappings for the compiler invocation.
CINDEX_LINKAGE CXString clang_CompileCommand_getMappedSourcePath (CXCompileCommand, unsigned I)
 Get the I'th mapped source path for the compiler invocation.
CINDEX_LINKAGE CXString clang_CompileCommand_getMappedSourceContent (CXCompileCommand, unsigned I)
 Get the I'th mapped source content for the compiler invocation.

Typedef Documentation

typedef void* CXCompilationDatabase

A compilation database holds all information used to compile files in a project. For each file in the database, it can be queried for the working directory or the command line used for the compiler invocation.

Must be freed by clang_CompilationDatabase_dispose

Definition at line 38 of file CXCompilationDatabase.h.

typedef void* CXCompileCommand

Represents the command line invocation to compile a specific file.

Definition at line 54 of file CXCompilationDatabase.h.

typedef void* CXCompileCommands

Contains the results of a search in the compilation database.

When searching for the compile command for a file, the compilation db can return several commands, as the file may have been compiled with different options in different places of the project. This choice of compile commands is wrapped in this opaque data structure. It must be freed by clang_CompileCommands_dispose.

Definition at line 49 of file CXCompilationDatabase.h.

Function Documentation

Free the given compilation database.

Creates a compilation database from the database found in directory buildDir. For example, CMake can output a compile_commands.json which can be used to build the database.

It must be freed by clang_CompilationDatabase_dispose.

Get all the compile commands in the given compilation database.

Find the compile commands used for a file. The compile commands must be freed by clang_CompileCommands_dispose.

Get the I'th argument value in the compiler invocations.

Invariant :

  • argument 0 is the compiler executable

Get the working directory where the CompileCommand was executed from.

Get the I'th mapped source content for the compiler invocation.

Get the I'th mapped source path for the compiler invocation.

Get the number of arguments in the compiler invocation.

Get the number of source mappings for the compiler invocation.

Free the given CompileCommands.

Get the I'th CompileCommand for a file.

Note : 0 <= i < clang_CompileCommands_getSize(CXCompileCommands)

Get the number of CompileCommand we have for a file.
