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.

General	`exists` `isDir` `isFile` `isSymlink` `rename` `thisExePath`
Directories	`chdir` `dirEntries` `getcwd` `mkdir` `mkdirRecurse` `rmdir` `rmdirRecurse` `tempDir`
Files	`append` `copy` `read` `readText` `remove` `slurp` `write`
Symlinks	`symlink` `readLink`
Attributes	`attrIsDir` `attrIsFile` `attrIsSymlink` `getAttributes` `getLinkAttributes` `getSize` `setAttributes`

Other	`DirEntry` `FileException` `PreserveAttributes` `SpanMode` `getAvailableDiskSpace`

Functions

Name	Description
`append(name, buffer)`	Appends `buffer` to file `name`.
`attrIsDir(attributes)`	Returns whether the given file attributes are for a directory.
`attrIsFile(attributes)`	Returns whether the given file attributes are for a file.
`attrIsSymlink(attributes)`	Returns whether the given file attributes are for a symbolic link.
`chdir(pathname)`	Change directory to `pathname`. Equivalent to `cd` on Windows and POSIX.
`copy(from, to, preserve)`	Copy file `from` to file `to`. File timestamps are preserved. File attributes are preserved, if `preserve` equals `Yes.preserveAttributes`. On Windows only `Yes.preserveAttributes` (the default on Windows) is supported. If the target file exists, it is overwritten.
`dirEntries(path, mode, followSymlink)`	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 how the directory is traversed. The name of each iterated directory entry contains the absolute or relative path (depending on pathname).
`exists(name)`	Determine whether the given file (or directory) exists.
`getAttributes(name)`	Returns the attributes of the given file.
`getAvailableDiskSpace(path)`	Returns the available disk space based on a given path. On Windows, `path` must be a directory; on POSIX systems, it can be a file or directory.
`getcwd()`	Get the current working directory.
`getLinkAttributes(name)`	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(name)`	Get size of file `name` in bytes.
`getTimes(name, accessTime, modificationTime)`	Get the access and modified times of file or folder `name`.
`getTimesWin(name, fileCreationTime, fileAccessTime, fileModificationTime)`	This function is Windows-Only.
`isDir(name)`	Returns whether the given file is a directory.
`isFile(name)`	Returns whether the given file (or directory) is a file.
`isSymlink(name)`	Returns whether the given file is a symbolic link.
`mkdir(pathname)`	Make a new directory `pathname`.
`mkdirRecurse(pathname)`	Make directory and all parent directories as needed.
`read(name, upTo)`	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(link)`	This function is POSIX-Only.
`readText(name)`	Reads and validates (using `validate`) a text file. S can be an array of any character type. However, no width or endian conversions are performed. So, if the width or endianness of the characters in the given file differ from the width or endianness of the element type of S, then validation will fail.
`remove(name)`	Delete file `name`.
`rename(from, to)`	Rename file `from` to `to`, moving it between directories if required. If the target file exists, it is overwritten.
`rmdir(pathname)`	Remove directory `pathname`.
`rmdirRecurse(pathname)`	Remove directory and all of its content and subdirectories, recursively.
`setAttributes(name, attributes)`	Set the attributes of the given file.
`setTimes(name, accessTime, modificationTime)`	Set access/modified times of file or folder `name`.
`slurp(filename, format)`	Reads a file line by line and parses the line into a single value or a `Tuple` of values depending on the length of `Types`. The lines are parsed using the specified format string. The format string is passed to `std.format.formattedRead`, and therefore must conform to the format string specification outlined in `std.format`.
`symlink(original, link)`	This function is POSIX-Only.
`tempDir()`	Returns the path to a directory for temporary files.
`thisExePath()`	Returns the full path of the current executable.
`timeLastAccessed(statbuf)`	This function is POSIX-Only.
`timeLastModified(name)`	Returns the time that the given file was last modified.
`timeLastModified(name, returnIfMissing)`	Returns the time that the given file was last modified. If the file does not exist, returns `returnIfMissing`.
`timeLastModified(statbuf)`	This function is POSIX-Only.
`timeStatusChanged(statbuf)`	This function is POSIX-Only.
`write(name, buffer)`	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 `Yes.preserveAttributes` on Windows, and the opposite on all other platforms.
