dmd.root.filename

Compiler implementation of the D programming language http://dlang.org
Authors:
struct FileName;
Encapsulate path and file names.
nothrow this(const(char)[] str);
static pure nothrow bool equals(const(char)* name1, const(char)* name2);

static pure nothrow bool equals(const(char)[] name1, const(char)[] name2);
Compare two name according to the platform's rules (case sensitive or not)
static pure nothrow bool absolute(const(char)* name);

static pure nothrow bool absolute(const(char)[] name);
Determine if path is absolute.
Parameters:
const(char)* name path
Returns:
true if absolute path name.
static nothrow const(char)* toAbsolute(const(char)* name, const(char)* base = null);
Return the given name as an absolute path
Parameters:
const(char)* name path
const(char)* base the absolute base to prefix name with if it is relative
Returns:
name as an absolute path relative to base
static pure nothrow const(char)* ext(const(char)* str);

static pure nothrow @nogc @safe const(char)[] ext(const(char)[] str);
Determine file name extension as slice of input.
Parameters:
const(char)* str file name
Returns:
filename extension (read-only). Points past '.' of extension. If there isn't one, return null.
static nothrow const(char)* removeExt(const(char)* str);

static nothrow const(char)[] removeExt(const(char)[] str);
Return file name without extension.

TODO Once slice are used everywhere and \0 is not assumed, this can be turned into a simple slicing.

Parameters:
const(char)* str file name
Returns:
mem.xmalloc'd filename with extension removed.
static pure nothrow const(char)* name(const(char)* str);

static pure nothrow const(char)[] name(const(char)[] str);
Return filename name excluding path (read-only).
static nothrow const(char)* path(const(char)* str);

static nothrow const(char)[] path(const(char)[] str);
Return path portion of str. Path will does not include trailing path separator.
static nothrow const(char)[] replaceName(const(char)[] path, const(char)[] name);
Replace filename portion of path.
static nothrow const(char)* combine(const(char)* path, const(char)* name);

static nothrow const(char)[] combine(const(char)[] path, const(char)[] name);
Combine a path and a file name
Parameters:
const(char)* path Path to append to
const(char)* name Name to append to path
Returns:
The \0 terminated string which is the combination of path and name and a valid path.
static nothrow char[] addExt(const(char)[] name, const(char)[] ext);
Add the extension ext to name, regardless of the content of name
Parameters:
const(char)[] name Path to append the extension to
const(char)[] ext Extension to add (should not include '.')
Returns:
A newly allocated string (free with FileName.free)
static nothrow const(char)* defaultExt(const(char)* name, const(char)* ext);

static nothrow const(char)[] defaultExt(const(char)[] name, const(char)[] ext);
Free returned value with FileName::free()
static nothrow const(char)* forceExt(const(char)* name, const(char)* ext);

static nothrow const(char)[] forceExt(const(char)[] name, const(char)[] ext);
Free returned value with FileName::free()
static pure nothrow bool equalsExt(const(char)* name, const(char)* ext);

static pure nothrow bool equalsExt(const(char)[] name, const(char)[] ext);
Returns:
true if name's extension is ext
const pure nothrow bool equalsExt(const(char)* ext);
Return !=0 if extensions match.
static nothrow const(char)* searchPath(Strings* path, const(char)* name, bool cwd);
Search Path for file.

Input cwd if true, search current directory before searching path

static nothrow const(char)* safeSearchPath(Strings* path, const(char)* name);
Search Path for file in a safe manner.
Be wary of CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') attacks. http://cwe.mitre.org/data/definitions/22.html More info: https://www.securecoding.cert.org/confluence/display/c/FIO02-C.+Canonicalize+path+names+originating+from+tainted+sources
Returns:
NULL file not found !=NULL mem.xmalloc'd file name
static nothrow int exists(const(char)* name);

static nothrow int exists(const(char)[] name);
Check if the file the path points to exists
Returns:
0 if it does not exists 1 if it exists and is not a directory 2 if it exists and is a directory
static nothrow bool ensurePathExists(const(char)* path);
Ensure that the provided path exists
Accepts a path to either a file or a directory. In the former case, the basepath (path to the containing directory) will be checked for existence, and created if it does not exists. In the later case, the directory pointed to will be checked for existence and created if needed.
Parameters:
const(char)* path a path to a file or a directory
Returns:
true if the directory exists or was successfully created
static nothrow const(char)* canonicalName(const(char)* name);

static nothrow const(char)[] canonicalName(const(char)[] name);
Return canonical version of name in a malloc'd buffer. This code is high risk.
static nothrow void free(const(char)* str);
Free memory allocated by FileName routines
auto absPathThen(alias F)(const(char)[] fileName);
Takes a callable F and applies it to the result of converting fileName to an absolute file path (char*)
Parameters:
const(char)[] fileName The file name to be converted to an absolute path
Returns:
Whatever F returns.
