Introduction

This example shows how to use the builtin Iguana file APIs to load, save and rename files. In this example we just use the bare API calls, but these are all potential candidates for creating small extension/helper functions.

If you have any questions please contact us at support@interfaceware.com.

Using the Code [top]

• Import the Load and Save a File channel from the Builtin: Iguana Files repository
• Experiment with the code to find out how it works
• Adapt the code to your own requirements

This is the github code for the main module:

How it works [top]

• We use iguana.workingDir() to find the working directory
• Save a file, or create it if it doesn’t exist:
  • Use io.open() to open a file, or create it if it doesn’t exist
  • Use io.filehandle.write() to write data to the file
  • Use io.filehandle.close() to close the file
    Note: Closing a file after you have finished using it is good practice particularly with Windows
• Open a file for reading:
  • Use io.open() to open a file
  • Use io.filehandle.read() to read data from the file
  • Use io.filehandle.close() to close the file
• Rename a file
  • Use os.rename() to rename a file
• Delete a file
  • Use os.remove() to delete a file
