# ScriptForge.FileSystem service

The FileSystem service includes routines to handle files and folders. Next are some examples of the features provided by this service:

- Verify whether a file or folder exists.

- Create and delete folders and files.

- Launch dialog boxes to open/save files.

- Access the list of files in a folder, etc.

The methods in the FileSystem service are mostly based on the XSimpleFileAccess UNO interface.

## Definitions

The table below lists the main parameters used by most of the methods in the FileSystem service.

Parameter | Description
--- | ---
FileName | The full name of the file including the path without a path separator at the end.
FolderName | The full name of the folder including the path. It may or may not contain the ending path separator.
Name | The last component of the Folder Name or File Name including its extension. This parameter is always expressed using the native format of the operating system.
BaseName | The last component of the Folder Name or File Name without its extension.

NamePattern

Any of the above names containing wildcards in its last component. Admitted wildcards are:

- "?" represents any single character

- "*" represents zero, one, or multiple characters

The FileSystem service allows to perform operations over multiple files at the same time. By using name patterns, user scripts can copy, move or delete multiple files. Conversely, Basic built-in methods can only handle single files.

### File Naming Notation

The notation used to express file and folder names, both for arguments and returned values, is defined by the FileNaming property of the FileSystem service.

In short, the possible representation types are "URL" (URL file notation), "SYS" (operating system notation) and "ANY" (default). See more information below.

An example of the URL notation is file:///C:/Documents/my_file.odt. Whenever possible consider using the URL notation because it is a more portable alternative.

The use of the shortcut "~" (tilde), which is common in Linux-based operating systems, is not supported to express a path to a folder and file name. Instead of using "~/Documents/my_file.odt" use the full path "/home/user/Documents/my_file.odt".

## Service invocation

The following code snippet invokes the FileSystem service. The method BuildPath was used as an example.

##### In Basic

          GlobalScope.BasicLibraries.LoadLibrary("ScriptForge")
          Dim FSO As Object
          Set FSO = CreateScriptService("FileSystem")
          FSO.BuildPath(...)

##### In Python

          from scriptforge import CreateScriptService
          fs = CreateScriptService("FileSystem")
          fs.BuildPath(...)

## Accessing the Virtual File System of a Document

LibreOffice document files are compressed ZIP files that contain the files and folders that represent the actual document contents. While the document is open, it is possible to access this virtual file system, explore its structure, as well as read and create files and folders.

The following example shows how to create a text file named myFile.txt and store it inside the document's virtual file system.

##### In Basic

        GlobalScope.BasicLibraries.LoadLibrary("ScriptForge")
        Dim oDoc As Object, fso As Object, oFile As Object
        Dim sRoot, sFile, sMyDir
        Set fso = CreateScriptService("FileSystem")
        Set oDoc = CreateScriptService("Document", ThisComponent)
        ' Gets the URL path notation to the root of the virtual file system
        sRoot = oDoc.FileSystem()
        sMyDir = sRoot & "myDir"
        ' Creates the folder "myDir" if it does not exist
        If Not fso.FolderExists(sMyDir) Then
            fso.CreateFolder(sMyDir)
        End If
        ' Creates the file and write some text into it
        sFile = fso.BuildPath(sMyDir, "myFile.txt")
        oFile = fso.CreateTextFile(sFile)
        oFile.WriteLine("Hello!")
        oFile.CloseFile()

##### In Python

        from scriptforge import CreateScriptService
        bas = CreateScriptService("Basic")
        doc = CreateScriptService("Document", bas.ThisComponent)
        fso = CreateScriptService("FileSystem")
        sRoot = doc.FileSystem
        sMyDir = sRoot + "myDir"
        if not fso.FolderExists(sMyDir):
            fso.CreateFolder(sMyDir)
        sFile = fso.BuildPath(sMyDir, "myFile.txt")
        oFile = fso.CreateTextFile(sFile)
        oFile.WriteLine("Hello!")
        oFile.CloseFile()

In general, all methods of the FileSystem service can be used to manipulate files in the document's virtual file system. However, the following restrictions apply:

- It is not possible to create files in the root folder. Use existing subfolders or create new folders to store files in the document's file system.

- The FileNaming notation is always considered to be "URL".

- The methods CompareFiles, GetFileModified, HashFile, PickFile and PickFolder are not applicable.

- The method GetFileLen always returns zero.

- The method Normalize always returns the input string unchanged.

The path to the virtual file system is not a physical address on the computer's hard drive. It can only be accessed from within a LibreOffice script and it only exists while the document file is open.

## Properties

Name | Readonly | Type | Description
--- | --- | --- | ---

FileNaming

No

String

Sets or returns the current files and folders notation, either "ANY", "URL" or "SYS":

- "ANY": (default) the methods of the FileSystem service accept both URL and current operating system's notation for input arguments but always return URL strings.

- "URL": the methods of the FileSystem service expect URL notation for input arguments and return URL strings.

- "SYS": the methods of the FileSystem service expect current operating system's notation for both input arguments and return strings.

Once set, the FileNaming property remains unchanged either until the end of the LibreOffice session or until it is set again.

ConfigFolder | Yes | String | Returns the configuration folder of LibreOffice.
ExtensionsFolder | Yes | String | Returns the folder where extensions are installed.
HomeFolder | Yes | String | Returns the user home folder.
InstallFolder | Yes | String | Returns the installation folder of LibreOffice.
TemplatesFolder | Yes | String | Returns the folder containing the system templates files.
TemporaryFolder | Yes | String | Returns the temporary files folder defined in the LibreOffice path settings.
UserTemplatesFolder | Yes | String | Returns the folder containing the user-defined template files.

          if fs.FileExists(r"C:\Documents\my_file.odt"):
              # ...

## Files

Returns a zero-based array (BASIC) or tuple (Python) of the files stored in a given folder. Each entry in the array or tuple is a string containing the full path and file name.

If the argument foldername specifies a folder that does not exist, an exception is raised.

The resulting list may be filtered with wildcards.

### Syntaksi:

svc.Files(foldername: str, filter: str = '', includesubfolders: bool = False): str[0..*]

### Parametrit:

foldername: A string representing a folder. The folder must exist. This argument must not designate a file.

filter: A string containing wildcards ("?" and "*") that will be applied to the resulting list of files (default = "").

includesubfolders: Set this argument to True to include the contents of subfolders (Default = False).

### Esimerkki:

##### In Basic

          Dim filesList As Variant, file As String
          FSO.FileNaming = "SYS"
          ' Returns all files matching the "*.txt" filter, including files in subfolders
          filesList = FSO.Files("/home/user/", "*.txt", IncludeSubfolders := True)
          For Each file In filesList
              ' ...
          Next file

filename: A string representing the file name and its path.

### Esimerkki:

In the examples below, the first GetBaseName method call corresponds to a folder, so the function returns the last component of the path. The second call receives a file name as input, so the name of the file is returned without its extension.

##### In Basic

          MsgBox FSO.GetBaseName("/home/user/Documents") ' "Documents"
          MsgBox FSO.GetBaseName("/home/user/Documents/my_file.ods") ' "my_file"

## GetExtension

Returns the extension part of a file or folder name without the dot "." character.

The method does not check for the existence of the specified file or folder.

If this method is applied to a folder name or to a file without an extension, then an empty string is returned.

### Syntaksi:

svc.GetExtension(filename: str): str

### Parametrit:

filename: A string representing the file name and its path.

          # Python
          ext = fs.GetExtension(r"C:\Windows\Notepad.exe")  # "exe"

## GetFileLen

The builtin FileLen Basic function returns the number of bytes contained in a file as a Long value, i.e. up to 2GB.

The GetFileLen method can handle files with much larger sizes by returning a Currency value.

### Syntaksi:

svc.GetFileLen(filename: str): num

### Parametrit:

filename: A string representing an existing file.

### Esimerkki:

##### In Basic

          Dim fLen As Currency
          FSO.FileNaming = "SYS"
          fLen = FSO.GetFileLen("C:\pagefile.sys")

filename: A string representing the file name and its path.

### Esimerkki:

          ' Basic
          a = FSO.GetName("C:\Windows\Notepad.exe")  ' Notepad.exe

          # Python
          a = fs.GetName(r"C:\Windows\Notepad.exe")  # Notepad.exe

## GetParentFolderName

Returns a string containing the name of the parent folder of a specified file or folder name.

The method does not check if the specified file or folder exists.

### Syntaksi:

svc.GetParentFolderName(filename: str): str

### Parametrit:

filename: A string with the file or folder name to be analyzed.

### Esimerkki:

          ' Basic
          a = FSO.GetParentFolderName("C:\Windows\Notepad.exe")  ' C:\Windows\

          # Python
          a = fs.GetParentFolderName(r"C:\Windows\Notepad.exe")  # C:\Windows\

## GetTempName

Returns a randomly generated temporary file name that is useful for performing operations that require a temporary file.

By default, the returned file name does not have an extension. Use the extension parameter to specify the extension of the file name to be generated.

The folder part of the returned string is the system's temporary folder.

The method does not create the temporary file.

### Syntaksi:

svc.GetTempName(extension: str): str

### Parametrit:

extension: The extension of the temporary file name (Default = "").

### Esimerkki:

##### In Basic

          Dim fName As String
          FSO.FileNaming = "SYS"
          fName = FSO.GetTempName(Extension := "txt")
          ' "/tmp/SF_574068.txt"

##### In Python

          fs.FileNaming = "SYS"
          fName = FSO.GetTempName(extension = "txt")
          # "/tmp/SF_574068.txt"

## HashFile

Hash functions are used by some cryptographic algorithms, in digital signatures, message authentication codes, fraud detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more.

The HashFile method returns the result of a hash function, applied on a given file and using a specified algorithm. The returned value is a string of lower-case hexadecimal digits.

The hash algorithms supported are: MD5, SHA1, SHA224, SHA256, SHA384 and SHA512.

### Syntaksi:

svc.HashFile(filename: str, algorithm: str): str

### Parametrit:

filename: A string representing an existing file.

          # Python
          sHash = FSO.HashFile(r"C:\pagefile.sys", "MD5")

## MoveFile

Moves one or more files from one location to another. Returns True if at least one file has been moved or False if an error occurred.

An error will also occur if the source parameter uses wildcard characters and does not match any files.

The method stops immediately after it encounters an error. The method does not roll back nor does it undo changes made before the error occurred.

### Syntaksi:

svc.MoveFile(source: str, destination: str): bool

### Parametrit:

source: It can be a FileName or NamePattern to designate one or more files to be moved.

destination: If source is a FileName then this parameter indicates the new path and file name of the moved file.

If the move operation involves multiple files, then destination must be a folder name. If it does not exist, it is created.

If source and destination have the same parent folder, the method will rename the source.

Wildcard characters are not allowed in destination.

### Esimerkki:

In the following examples only files are moved, subfolders are not.

          ' Basic
          FSO.MoveFile("C:\Temp1\*.*", "C:\Temp2")

          # Python
          fs.MoveFile(r"C:\Temp1\*.*", r"C:\Temp2")

## MoveFolder

Moves one or more folders from one location to another. Returns True if at least one folder has been moved or False if an error occurred.

An error will also occur if the source parameter uses wildcard characters and does not match any folders.

The method stops immediately after it encounters an error. The method does not roll back nor does it undo changes made before the error occurred.

### Syntaksi:

svc.MoveFolder(source: str, destination: str): bool

### Parametrit:

source: It can be a FolderName or NamePattern to designate one or more folders to be moved.

destination: If the move operation involves a single folder, then destination is the name and path of the moved folder and it must not exist.

If multiple folders are being moved, then destination designates where the folders in source will be moved into. If destination does not exist, it is created.

Wildcard characters are not allowed in destination.

### Esimerkki:

          ' Basic
          FSO.MoveFolder("C:\Temp1\*", "C:\Temp2")

          # Python
          fs.MoveFolder(r"C:\Temp1\*", r"C:\Temp2")

## Normalize

Returns a string containing the normalized path name by collapsing redundant separators and up-level references.

For instance, the path names A//B, A/B/, A/./B and A/foo/../B are all normalized to A/B.

On Windows, forward slashes "/" are converted to backward slashes "\".

The current value of the property SF_FileSystem.FileNaming is used to determine the notation of the filename argument as well as the format of the returned string.

### Syntaksi:

svc.Normalize(filename: str): str

### Parametrit:

filename: a string representing a valid path name. The file or directory represented by this argument may not exist.

### Esimerkki:

##### In Basic

        FSO.FileNaming = "URL"
        ' file:///home/user/Documents
        normPath = FSO.Normalize("file:///home/user/Documents/")
        ' file:///home/user/Documents
        normPath = FSO.Normalize("file:///home//user//Documents/")
        ' file:///home/user
        normPath = FSO.Normalize("file:///home//user//Documents/../")

##### In Python

        fs.FileNaming = "URL"
        normPath = fs.Normalize("file:///home/user/Documents/")
        normPath = fs.Normalize("file:///home//user//Documents/")
        normPath = fs.Normalize("file:///home//user//Documents/../")

## OpenTextFile

Opens a file and returns a TextStream object that can be used to read from, write to, or append to the file.

Note that the method does not check if the given file is really a text file.

The method returns a Null object (in Basic) or None (in Python) if an error occurred.

### Syntaksi:

svc.OpenTextFile(filename: str, iomode: int = 1, create: bool = False, encoding: str = 'UTF-8'): svc

### Parametrit:

filename: Identifies the file to open.

iomode: Indicates the input/output mode. It can be one of three constants: svc.ForReading (default), svc.ForWriting, or svc.ForAppending.

create: Boolean value that indicates whether a new file can be created if the specified filename doesn't exist:

- If True a new file and its parent folders will be created if they do not exist;

- If False then new files are not created (default).

encoding: The character set to be used. The default encoding is "UTF-8".

### Esimerkki:

##### In Basic

          Dim myFile As Object
          FSO.FileNaming = "SYS"
          Set myFile = FSO.OpenTextFile("C:\Temp\ThisFile.txt", FSO.ForReading)
          If Not IsNull(myFile) Then
              ' ...
          End If

##### In Python

          fs.FileNaming = "SYS"
          myFile = fs.OpenTextFile(r"C:\Temp\ThisFile.txt", fs.ForReading)
          if myFile is not None:
              # ...

## PickFile

Opens a dialog box to open or save files.

If the SAVE mode is set and the picked file exists, a warning message will be displayed.

### Syntaksi:

svc.PickFile(defaultfile: str ='', mode: str = 'OPEN', filter: str = ''): str

### Parametrit:

defaultfile: This argument is a string composed of a folder and file name:

- The folder part indicates the folder that will be shown when the dialog opens (default = the last selected folder).

- The file part designates the default file to open or save.

mode: A string value that can be either "OPEN" (for input files) or "SAVE" (for output files). The default value is "OPEN".

filter: The extension of the files displayed when the dialog is opened (default = no filter).

### Esimerkki:

The examples below open a file picker with the "txt" filter applied.

          ' Basic
          aFile = FSO.PickFile("C:\Documents", "OPEN", "txt")

          # Python
          aFile = fs.PickFile(r"C:\Documents", "OPEN", "txt")

## PickFolder

Opens a dialog box to select a folder.

### Syntaksi:

svc.PickFolder(defaultfolder: str = '', freetext: str = ''): str

### Parametrit:

defaultfolder: A string containing the folder name that will be displayed when the dialog is opened (default = the last selected folder).

freetext: Text to display in the dialog (default = "").

### Esimerkki:

          ' Basic
          aFolder = FSO.PickFolder("C:\Documents", "Choose a folder or press Cancel")

          # Python
          aFolder = fs.PickFolder(r"C:\Documents", "Choose a folder or press Cancel")

## SubFolders

Returns a zero-based array of strings corresponding to the folders stored in a given foldername.

The list may be filtered with wildcards.

### Syntaksi:

svc.SubFolders(foldername: str, filter: str = '', includesubfolders: bool = False): str[0..*]

### Parametrit:

foldername: A string representing a folder. The folder must exist. foldername must not designate a file.

filter: A string containing wildcards ("?" and "*") that will be applied to the resulting list of folders (default = "").

includesubfolders: Set this argument to True to include the contents of subfolders (Default = False).

### Esimerkki:

##### In Basic

          Dim folderList As Variant, folder As String
          FSO.FileNaming = "SYS"
          folderList = FSO.SubFolders("/home/user/")
          For Each folder In folderList
              ' ...
          Next folder

##### In Python

          fs.FileNaming = "SYS"
          folderList = fs.SubFolders("/home/user/")
          for folder in folderList:
              # ...
