Function std.file.setAttributes

Set the attributes of the given file.

void setAttributes(R) (
  R name,
  uint attributes
)
if (isInputRange!R && !isInfinite!R && isSomeChar!(ElementEncodingType!R) && !isConvertibleToString!R);

void setAttributes(R) (
  auto ref R name,
  uint attributes
)
if (isConvertibleToString!R);

For example, a programmatic equivalent of Unix's chmod +x name to make a file executable is name.setAttributes(name.getAttributes | octal!700).

Parameters

NameDescription
name the file name
attributes the attributes to set the file to

Throws

FileException if the given file does not exist.

Example

setAttributes with a file 

import std.exception : assertThrown;
import std.conv : octal;

auto f = deleteme ~ "file";
version (Posix)
{
    scope(exit) f.remove;

    assert(!f.exists);
    assertThrown!FileException(f.setAttributes(octal!777));

    f.write(".");
    auto attributes = f.getAttributes;
    assert(!attributes.attrIsDir);
    assert(attributes.attrIsFile);

    f.setAttributes(octal!777);
    attributes = f.getAttributes;

    writeln((attributes & 1023)); // octal!777
}

Example

setAttributes with a directory 

import std.exception : assertThrown;
import std.conv : octal;

auto dir = deleteme ~ "dir";
version (Posix)
{
    scope(exit) dir.rmdir;

    assert(!dir.exists);
    assertThrown!FileException(dir.setAttributes(octal!777));

    dir.mkdir;
    auto attributes = dir.getAttributes;
    assert(attributes.attrIsDir);
    assert(!attributes.attrIsFile);

    dir.setAttributes(octal!777);
    attributes = dir.getAttributes;

    writeln((attributes & 1023)); // octal!777
}
