Servicio ScriptForge.FileSystem

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

note

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


Definiciones

La tabla de más abajo enumera los principales parámetros que utiliza la mayoría de los métodos del servicio FileSystem.

Parámetro

Descripción

FileName

El nombre completo del archivo, la ruta incluida, sin esta incluir el separador de ruta al final.

FolderName

El nombre completo de la carpeta, ruta incluida, con o sin el separador de ruta final.

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:

  • «?» representa cualquier carácter individual

  • «*» representa cero, uno o múltiples caracteres


tip

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.


Notación para dar nombre a los archivos

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.

tip

Un ejemplo de notación de URL es file:///C:/Documents/mi_archivo.odt. Considere, siempre que sea posible, utilizar la notación de URL, dado que es una alternativa más portátil.


warning

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".


Invocación del servicio

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

En BASIC

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

En 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()
  
En 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:

note

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.

Sintaxis:

svc.BuildPath(foldername: str, name: str): str

Parámetros:

foldername: The path with which name will be combined. The specified path does not need to be an existing folder.

name: The name of the file to be appended to foldername. This parameter uses the notation of the current operating system.

Ejemplo:

En BASIC

      Dim FSO as Object
      Set FSO = CreateScriptService("FileSystem")
      Dim aFileName as String
      FSO.FileNaming = "URL"
      aFileName = FSO.BuildPath("file:///home/user", "sample file.odt")
      ' file:///home/user/sample%20file.odt
    
En Python

      fs = CreateScriptService("FileSystem")
      fs.FileNaming = "URL"
      aFileName = fs.BuildPath("file:///home/user", "sample file.odt")
      # file:///home/user/sample%20file.odt
    

CompareFiles

Compares two files and returns True when they seem identical.

Depending on the value of the comparecontents argument, the comparison between both files can be either based only on file attributes (such as the last modified date), or based on the file contents.

Sintaxis:

svc.CompareFiles(filename1: str, filename2: str, comparecontents: bool = False): bool

Parámetros:

filename1, filename2: The files to compare.

comparecontents: When True, the contents of the files are compared (default = False).

Ejemplo:

En BASIC

      FSO.FileNaming = "SYS"
      If FSO.CompareFiles("C:\myFile1.txt", "C:\myFile2.txt", CompareContents := False) Then
          ' ...
      End If
    
En Python

      fs.FileNaming = "SYS"
      if fs.CompareFiles(r"C:\myFile1.txt", r"C:\myFile2.txt", comparecontents = False):
          # ...
    

CopyFile

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

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

El método se para inmediatamente después de que encuentra un error. El método no se revierte ni se deshacen los cambios efectuados antes de ocurrir el error.

Sintaxis:

svc.CopyFile(source: str, destination: str, overwrite: bool = True): bool

Parámetros:

source: It can be a FileName or a NamePattern indicating one or more files to be copied.

destination: It can be either a FileName specifying where the single source file is to be copied, or a FolderName into which the multiple files from source are to be copied.

overwrite: If True (default), files may be overwritten. The method will fail if destination is readonly, regardless of the value specified in overwrite.

Ejemplo:

In the examples below the first line copies a single file whereas the second line copies multiple files using wildcards.

En BASIC

      FSO.CopyFile("C:\Documents\my_file.odt", "C:\Temp\copied_file.odt")
      FSO.CopyFile("C:\Documents\*.*", "C:\Temp\", Overwrite := False)
    
En Python

      fs.CopyFile(r"C:\Documents\my_file.odt", r"C:\Temp\copied_file.odt")
      fs.CopyFile(r"C:\Documents\*.*", r"C:\Temp", overwrite = False)
    
note

Conviene tener presente que las subcarpetas y sus contenidos no se copian cuando se utilizan comodines en el argumento source.

      ' file:///home/username/.config/libreoffice/4/user/uno_packages/cache/uno_packages/lu10833wz3u2i.tmp_/apso_1_2_7.oxt
    

      # Python
      sFolder = fs.ExtensionFolder("apso.python.script.organizer")
    

FileExists

Devuelve True si un nombre de archivo indicado es válido y existe; si no, el método devuelve False.

If the filename parameter is actually an existing folder name, the method returns False.

Sintaxis:

svc.FileExists(filename: str): bool

Parámetros:

filename: A string representing the file to be tested.

Ejemplo:

En BASIC

      FSO.FileNaming = "SYS"
      If FSO.FileExists("C:\Documents\my_file.odt") Then
          '...
      End If
    
En Python

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

Files

Returns a zero-based array of the files stored in a given folder. Each entry in the array 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.

Es posible filtrar la lista resultante mediante comodines.

Sintaxis:

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

Parámetros:

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).

Ejemplo:

En 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
    
En Python

      fs.FileNaming = "SYS"
      filesList = fs.Files("/home/user/", "*.txt", includesubfolders = True)
      for file in fileList:
          # ...
    

FolderExists

Devuelve True si el FolderName especificado es válido y existe; si no, el método devuelve False.

If the foldername parameter is actually an existing file name, the method returns False.

Sintaxis:

svc.FolderExists(foldername: str): bool

      if fs.FolderExists(r"C:\Documents\Thesis")
          # ...
    

GetBaseName

Returns the BaseName (equal to the last component) of a folder or file name, without its extension.

El método no comprueba si existe el archivo o la carpeta que se especificó.

Sintaxis:

svc.GetBaseName(filename: str): str

Parámetros:

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

Ejemplo:

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.

En BASIC

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

      bas = CreateScriptService("Basic")
      bas.MsgBox(fs.GetBaseName("/home/user/Documents")) # "Documents"
      bas.MsgBox(fs.GetBaseName("/home/user/Documents/my_file.ods")) # "my_file"
    

GetExtension

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

El método no comprueba la existencia del archivo o la carpeta que se haya especificado.

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

Sintaxis:

svc.GetExtension(filename: str): str

Parámetros:

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

Ejemplo:


      ' Basic
      ext = FSO.GetExtension("C:\Windows\Notepad.exe")  ' "exe"
    

      # 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.

Sintaxis:

svc.GetFileLen(filename: str): num

Parámetros:

filename: A string representing an existing file.

Ejemplo:

En BASIC

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

      fs.FileNaming = "SYS"
      fLen = fs.GetFileLen(r"C:\pagefile.sys")
    

GetFileModified

Devuelve la fecha de última modificación de un archivo determinado.

Sintaxis:

svc.GetFileModified(filename: str): datetime

Parámetros:

filename: A string representing an existing file.

Ejemplo:

En BASIC

      Dim aDate As Date
      FSO.FileNaming = "SYS"
      aDate = FSO.GetFileModified("C:\Documents\my_file.odt")
    
En Python

      fs.FileNaming = "SYS"
      aDate = FSO.GetFileModified(r"C:\Documents\my_file.odt")
    

GetName

Returns the last component of a file or folder name in native operating system format.

El método no comprueba si existe el archivo o la carpeta que se especificó.

Sintaxis:

svc.GetName(filename: str): str

Parámetros:

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

Ejemplo:


      ' 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.

El método no comprueba si existe el archivo o la carpeta que se especificó.

Sintaxis:

svc.GetParentFolderName(filename: str): str

Parámetros:

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

Ejemplo:


      ' 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.

El método no crea el archivo temporal.

Sintaxis:

svc.GetTempName(extension: str): str

Parámetros:

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

Ejemplo:

En BASIC

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

Sintaxis:

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

Parámetros:

filename: A string representing an existing file.

algorithm: One of the supported algorithms.

Ejemplo:


      ' Basic
      sHash = FSO.HashFile("C:\pagefile.sys", "MD5")
    

      # 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.

El método se para inmediatamente después de que encuentra un error. El método no se revierte ni se deshacen los cambios efectuados antes de ocurrir el error.

Sintaxis:

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

Parámetros:

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.

Ejemplo:

En los ejemplos siguientes se mueven solo los archivos, no las subcarpetas.


      ' 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.

El método se para inmediatamente después de que encuentra un error. El método no se revierte ni se deshacen los cambios efectuados antes de ocurrir el error.

Sintaxis:

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

Parámetros:

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.

Ejemplo:


      ' 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.

En Windows, las barras (/) se convierten en contrabarras (\).

note

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.


Sintaxis:

svc.Normalize(filename: str): str

Parámetros:

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

Ejemplo:

En 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/../")
  
En 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.

Observe que el método no comprueba que el archivo indicado realmente sea de texto.

El método devuelve un objeto Null (en BASIC) o None (en Python) si ha ocurrido un error.

Sintaxis:

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

Parámetros:

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:

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

Ejemplo:

En BASIC

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