Functions | |
static PRStatus | PLearn::PR_GetFileInfo64_NoWildcards (const char *fn, PRFileInfo64 *info) |
Workaround for the fact that on Windows the PR_GetFileInfo function does a wildcard expansion of the filename before returning the file stats, which slows down (for example) lookups of the modification times for a number of files by a big factor on Windows. | |
int | PLearn::chdir (const PPath &path) |
Change current directory. | |
bool | PLearn::pathexists (const PPath &path) |
Returns true if the given path points to an existing regular file or directory. | |
bool | PLearn::isdir (const PPath &path) |
Returns true if the given path is an existing directory (or a symbolic link pointing to a directory). | |
bool | PLearn::isfile (const PPath &path) |
Returns true if the given path is an existing regular file (or a symbolic link pointing to a file). | |
bool | PLearn::isemptyFile (const PPath &path) |
Returns true if the given path is an existing regular file (or a symbolic link pointing to a file) and the size of the file is 0. | |
time_t | PLearn::mtime (const PPath &path) |
Returns the time of last modification of file (or 0 if file does not exist). | |
vector< string > | PLearn::lsdir (const PPath &dirpath) |
vector< PPath > | PLearn::lsdir_fullpath (const PPath &dirpath) |
Same as lsdir, except the returned entries are full paths. | |
bool | PLearn::mkdir_lowlevel (const PPath &dirname) |
Low-level cross-platform mkdir function, with the normal mkdir semantics. | |
bool | PLearn::force_mkdir (const PPath &dirname) |
void | PLearn::force_mkdir_for_file (const PPath &filepath) |
Extracts the directory part of the filepath and calls force_mkdir. | |
bool | PLearn::force_rmdir (const PPath &dirname) |
PRUint64 | PLearn::filesize64 (const PPath &filename) |
Returns the length of a file, measured in bytes, as a 64bit unsigned integer type defined by NSPR. | |
string | PLearn::loadFileAsString (const PPath &filepath) |
Returns the whole content of the file as a string. | |
void | PLearn::saveStringInFile (const PPath &filepath, const string &text) |
Writes the raw string into the given file. | |
void | PLearn::cp (const PPath &srcpath, const PPath &destpath) |
Calls system with cp -R to recursively copy source to destination. | |
bool | PLearn::rm (const PPath &file, bool fail_on_error_if_exist=false) |
Remove a file (return 'true' if removed sucessfully). | |
PRStatus | PLearn::mv (const PPath &source, const PPath &dest, bool fail_on_error=true) |
Calls system mv command to move the given source file to destination. | |
PRStatus | PLearn::mvforce (const PPath &source, const PPath &dest, bool fail_on_error=true) |
Same as mv, but will not prompt before overwriting. | |
void | PLearn::readWhileMatches (PStream &in, const string &s) |
Reads while the characters read exactly match those in s. | |
void | PLearn::skipRestOfLine (PStream &in) |
Skips everything until ' ' (also consumes the ' '). | |
void | PLearn::skipBlanksAndComments (PStream &in) |
Will skip all blanks (white space, newline and #-style comments). | |
void | PLearn::getNextNonBlankLine (PStream &in, string &line) |
Fills 'line' with the next non blank line (#-style comments are considered blank, and automatically stripped out of 'line'). | |
int | PLearn::countNonBlankLinesOfFile (const PPath &filename) |
Will return the number of non-blank lines of file. | |
PPath | PLearn::newFilename (const PPath &directory="/tmp/", const string &prefix="", bool is_directory=false) |
Returns a temporary file (or directory) name suitable for a unique (one time) use. | |
PPath | PLearn::makeFileNameValid (const PPath &filename) |
Return a valid filename from a potentially invalid one. | |
void | PLearn::touch (const PPath &file) |
Trivial unix touch. | |
void | PLearn::addFileAndDateVariables (const PPath &filepath, map< string, string > &variables, const time_t &latest) |
string | PLearn::readFileAndMacroProcess (const PPath &filepath, map< string, string > &variables, time_t &latest, bool change_dir) |
string | PLearn::readAndMacroProcess (PStream &in, map< string, string > &variables, time_t &latest, bool skip_comments=true) |
Will return the text, macro processed, with each instance of ${varname} in the text that corresponds to a key in the given map replaced by its associated value. | |
void | PLearn::addReferenceToFile (const PPath &file) |
Increase by one the number of references to a file. | |
bool | PLearn::noReferenceToFile (const PPath &file) |
Return 'true' iff there is no reference to a file. | |
unsigned int | PLearn::nReferencesToFile (const PPath &file) |
Return the number of references to a file. | |
void | PLearn::removeReferenceToFile (const PPath &file) |
Decrease by one the number of references to a file. | |
