# Path

The functions for manipulating filename paths are described here.

* [AbsPath( str path ) str](#abspath-str-path-str)
* [BaseName( str path ) str](#basename-str-path-str)
* [Dir( str path ) str](#dir-str-path-str)
* [Ext( str path ) str](#ext-str-path-str)
* [JoinPath( str path... ) str](#joinpath-str-path-str)
* [MatchPath( str pattern, str path ) bool](#matchpath-str-pattern-str-path-bool)
* [Path( finfo fi ) str](#path-finfo-fi-str)

## Functions

### AbsPath(str path) str

The *AbsPath* function returns an absolute representation of path.

### BaseName(str path) str

The *BaseName* function returns the last element of path. Trailing path separators are removed before extracting the last element. If the path is empty, the function returns ".".

### Dir(str path) str

The *Dir* function returns all but the last element of path, typically the path's directory.

### Ext(str path) str

The *Ext* function returns the file name extension. The result extension is without a dot.

### JoinPath(str path...) str

The *JoinPath* function joins any number of path elements into a single path, adding a separator if necessary.

### MatchPath(str pattern, str path) bool

The *MatchPath* function checks if the given name matches the specified pattern. The function checks the pattern completely for the specified path, not for the substring. You can use a regular expression as a pattern. To do this, add a */* at the beginning and end.

* '\*' - matches any sequence of non-separator characters
* '?' - matches any single non-separator character

```
MatchPath(`*.txt`, `myfile.txt`)       // true
MatchPath(`?a?.pdf`, `1ab.pdf`)        // true
MatchPath(`/home/ak/my.pdf`, `*.pdf`)         // false
MatchPath(`/home/ak/my.pdf`, `/home/*/my.*`)  // true
MatchPath(`/home/ak/my.pdf`, `/home/*/my.*`) // true
MatchPath(`/user/`, `/home/user/myfile`) // true
```

### Path(finfo fi) str

The *Path* function concatenates the *Name* and *Dir* fields of the *finfo* variable and returns the resulting path.
