Files and Directory Processing Using LibreOffice Calc Macro using Basic

This article demontrates how to process/read individual files and directories in Unix file system using Basic and LibreOffice Calc Macro and put the file names/directory names in LibreOffice Calc cells.

For LibreOffice automation, it is necessary to know file system and directory processings. This tutorial is based on Unix file system which is different than Windoze.

In this article, the macro would read the contents of an entire directory and find out the files and directories and list them in Calc cells. Say, the file system structure is like this in a typical Ubuntu system in the path /usr/include

There are lots of Directories and Files. We would like to list down entire contents inside Calc cells.
Basic provides function “Dir” which can be used to read the contents of a Directory.

Syntax


Dir (path, attributes) As String


First argument of the Dir function is the path string to be read. Second argument tells Dir function which type of elements in that path to be returned. Pass on “0” for file and “16” for Directories for second argument. Both the arguments are optional.

Once the first Dir call is successful, call the function again without argument inside a loop to get the same items from the function resulting listing of entire Directory contents.

Complete Macro

To run, create a new Calc file and Copy and paste this entire code block below in Macro Editor in LibreOffice and run.

Sub list_files()
    Dim i, strFile
    path ="/usr/include/"
    strFile = Dir(path,0)
    i = 1
    while strFile <> ""
        my_cell = ThisComponent.Sheets(0).getCellbyPosition(1,i)
        my_cell.String = strFile
        strFile = Dir ' returns next entry
        i = i + 1
    wend
End Sub

Sub list_directory()
    Dim i, strDir
    path ="/usr/include/"
    strDir = Dir(path, 16)
    i = 1
    while strDir <> ""
        my_cell = ThisComponent.Sheets(0).getCellbyPosition(2,i)
        my_cell.String = strDir
        strDir = Dir ' returns next entry
        i = i + 1
    wend
End Sub

Output

After run, the contents of /usr/include would be shown in Calc. First column would contain the Files and second column would contain the Directories.
