It " "overwrites the file if it already exists, and creates the file " "if it does not exist.\n" "APPEND will write a message into a file same as WRITE, except " "it will append it to the end of the file\n" "READ will read the content of a file and store it into the " "variable. It will start at the given offset and read up to numBytes. " "If the argument HEX is given, the binary data will be converted to " "hexadecimal representation and this will be stored in the variable.\n" "STRINGS will parse a list of ASCII strings from a file and " "store it in a variable. Binary data in the file are ignored. Carriage " "return (CR) characters are ignored. It works also for Intel Hex and " "Motorola S-record files, which are automatically converted to binary " "format when reading them. Disable this using NO_HEX_CONVERSION.\n" "LIMIT_COUNT sets the maximum number of strings to return. " "LIMIT_INPUT sets the maximum number of bytes to read from " "the input file. " "LIMIT_OUTPUT sets the maximum number of bytes to store in the " "output variable. " "LENGTH_MINIMUM sets the minimum length of a string to return. " "Shorter strings are ignored. " "LENGTH_MAXIMUM sets the maximum length of a string to return. Longer " "strings are split into strings no longer than the maximum length. " "NEWLINE_CONSUME allows newlines to be included in strings instead " "of terminating them.\n" "REGEX specifies a regular expression that a string must match to be " "returned. Typical usage \n" " file(STRINGS myfile.txt myfile)\n" "stores a list in the variable \"myfile\" in which each item is " "a line from the input file.\n" "GLOB will generate a list of all files that match the globbing " "expressions and store it into the variable. Globbing expressions " "are similar to regular expressions, but much simpler. If RELATIVE " "flag is specified for an expression, the results will be returned " "as a relative path to the given path.\n" "Examples of globbing expressions include:\n" " *.cxx - match all files with extension cxx\n" " *.vt? - match all files with extension vta,...,vtz\n" " f[3-5].txt - match files f3.txt, f4.txt, f5.txt\n" "GLOB_RECURSE will generate a list similar to the regular GLOB, except " "it will traverse all the subdirectories of the matched directory and " "match the files. Subdirectories that are symlinks are only traversed " "if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW. " "See cmake --help-policy CMP0009 for more information.\n" "Examples of recursive globbing include:\n" " /dir/*.py - match all python files in /dir and subdirectories\n" "MAKE_DIRECTORY will create the given directories, also if their parent " "directories don't exist yet\n" "REMOVE will remove the given files, also in subdirectories\n" "REMOVE_RECURSE will remove the given files and directories, also " "non-empty directories\n" "RELATIVE_PATH will determine relative path from directory to the given" " file.\n" "TO_CMAKE_PATH will convert path into a cmake style path with unix /. " " The input can be a single path or a system path like \"$ENV{PATH}\". " " Note the double quotes around the ENV call TO_CMAKE_PATH only takes " " one argument.\n" "TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from " " a cmake style path into the native path style \\ for windows and / " "for UNIX.\n" "DOWNLOAD will download the given URL to the given file. " "If LOG var is specified a log of the download will be put in var. " "If STATUS var is specified the status of the operation will" " be put in var. The status is returned in a list of length 2. " "The first element is the numeric return value for the operation, " "and the second element is a string value for the error. A 0 " "numeric error means no error in the operation. " "If TIMEOUT time is specified, the operation will " "timeout after time seconds, time can be specified as a float.\n"; } cmTypeMacro(cmFileCommand, cmCommand); protected: bool HandleRemove(std::vector const& args, bool recurse); bool HandleWriteCommand(std::vector const& args, bool append); bool HandleReadCommand(std::vector const& args); bool HandleStringsCommand(std::vector const& args); bool HandleGlobCommand(std::vector const& args, bool recurse); bool HandleMakeDirectoryCommand(std::vector const& args); bool HandleRelativePathCommand(std::vector const& args); bool HandleCMakePathCommand(std::vector const& args, bool nativePath); bool HandleRPathChangeCommand(std::vector const& args); bool HandleRPathCheckCommand(std::vector const& args); bool HandleRPathRemoveCommand(std::vector const& args); bool HandleDifferentCommand(std::vector const& args); // file(INSTALL ...) related functions bool HandleInstallCommand(std::vector const& args); bool ParseInstallArgs(std::vector const& args, cmFileInstaller& installer, std::map& properties, int& itype, std::string& destination, std::string& rename, std::vector& files, bool& optional ); bool DoInstall(cmFileInstaller& installer, const int itype, const std::string& rename, const std::string& destination, const std::vector& files, const bool optional ); bool HandleDownloadCommand(std::vector const& args); void GetTargetTypeFromString(const std::string& stype, int& itype) const; bool HandleInstallDestination(cmFileInstaller& installer, std::string& destination); void HandleInstallPermissions(cmFileInstaller& installer, mode_t& permissions_file, mode_t& permissions_dir, int itype, bool use_given_permissions_file, bool use_given_permissions_dir, bool use_source_permissions) const; }; #endif
