Function std.path.chainPath

Concatenate path segments together to form one path.

auto chainPath(R1, R2, Ranges...) (
  R1 r1,
  R2 r2,
  Ranges ranges
)
if ((isRandomAccessRange!R1 && hasSlicing!R1 && hasLength!R1 && isSomeChar!(ElementType!R1) || isNarrowString!R1 && !isConvertibleToString!R1) && (isRandomAccessRange!R2 && hasSlicing!R2 && hasLength!R2 && isSomeChar!(ElementType!R2) || isNarrowString!R2 && !isConvertibleToString!R2) && (Ranges.length == 0 || is(typeof(chainPath(r2, ranges)))));

Parameters

NameDescription
r1 first segment
r2 second segment
ranges 0 or more segments

Returns

Lazy range which is the concatenation of r1, r2 and ranges with path separators. The resulting element type is that of r1.

Example

import std.array;
version (Posix)
{
    writeln(chainPath("foo", "bar", "baz").array); // "foo/bar/baz"
    writeln(chainPath("/foo/", "bar/baz").array); // "/foo/bar/baz"
    writeln(chainPath("/foo", "/bar").array); // "/bar"
}

version (Windows)
{
    writeln(chainPath("foo", "bar", "baz").array); // `foo\bar\baz`
    writeln(chainPath(`c:\foo`, `bar\baz`).array); // `c:\foo\bar\baz`
    writeln(chainPath("foo", `d:\bar`).array); // `d:\bar`
    writeln(chainPath("foo", `\bar`).array); // `\bar`
    writeln(chainPath(`c:\foo`, `\bar`).array); // `c:\bar`
}

import std.utf : byChar;
