Module std.file

Utilities for manipulating files and scanning directories. Functions in this module handle files as a unit, e.g., read or write one file at a time. For opening files and manipulating them via handles refer to module std.stdio.

Functions

Name	Description
append	Appends buffer to file name.
attrIsDir	Returns whether the given file attributes are for a directory.
attrIsFile	Returns whether the given file attributes are for a file.
attrIsSymlink	Returns whether the given file attributes are for a symbolic link.
chdir	Change directory to pathname.
copy	Copy file from to file to. File timestamps are preserved. File attributes are preserved, if preserve equals PreserveAttributes.yes. On Windows only PreserveAttributes.yes (the default on Windows) is supported. If the target file exists, it is overwritten.
dirEntries	Convenience wrapper for filtering file names with a glob pattern.
dirEntries	Returns an input range of DirEntry that lazily iterates a given directory, also provides two ways of foreach iteration. The iteration variable can be of type string if only the name is needed, or DirEntry if additional details are needed. The span mode dictates the how the directory is traversed. The name of the each directory entry iterated contains the absolute path.
exists	Determine whether the given file (or directory) exists.
getAttributes	Returns the attributes of the given file.
getcwd	Get the current working directory.
getLinkAttributes	If the given file is a symbolic link, then this returns the attributes of the symbolic link itself rather than file that it points to. If the given file is not a symbolic link, then this function returns the same result as getAttributes.
getSize	Get size of file name in bytes.
getTimes	Get the access and modified times of file or folder name.
getTimesWin	This function is Windows-Only.
isDir	Returns whether the given file is a directory.
isFile	Returns whether the given file (or directory) is a file.
isSymlink	Returns whether the given file is a symbolic link.
mkdir	Make directory pathname.
mkdirRecurse	Make directory and all parent directories as needed.
read	Read entire contents of file name and returns it as an untyped array. If the file size is larger than upTo, only upTo bytes are read.
readLink	This function is Posix-Only.
readText	Read and validates (using std.utf.validate) a text file. S can be a type of array of characters of any width and constancy. No width conversion is performed; if the width of the characters in file name is different from the width of elements of S, validation will fail.
remove	Delete file name.
rename	Rename file from to to. If the target file exists, it is overwritten.
rmdir	Remove directory pathname.
rmdirRecurse	Remove directory and all of its content and subdirectories, recursively.
setAttributes	Set the attributes of the given file.
setTimes	Set access/modified times of file or folder name.
slurp	Reads an entire file into an array.
symlink	This function is Posix-Only.
tempDir	Returns the path to a directory for temporary files.
thisExePath	Returns the full path of the current executable.
timeLastModified	Returns the time that the given file was last modified. If the file does not exist, returns returnIfMissing.
timeLastModified	Returns the time that the given file was last modified.
write	Write buffer to file name.

Classes

Name	Description
FileException	Exception thrown for file I/O errors.

Structs

Name	Description
DirEntry	Info on a file, similar to what you'd get from stat on a Posix system.

Enums

Name	Description
SpanMode	Dictates directory spanning policy for dirEntries (see below).

Global variables

Name	Type	Description
preserveAttributesDefault	Flag!("preserveAttributes")	Defaults to PreserveAttributes.yes on Windows, and the opposite on all other platforms.
