I/O Spyder plugins

How to create your own I/O Spyder plugins:

  • Create a Python module named spyder_io_foobar where foobar is the name of your plugin

  • Write your loading function and/or your saving function:

    • load:
      • input is a string: filename
      • output is a tuple with two elements: dictionary containing at least one element (key is the variable name) and error message (or None)
    • save:
      • input is a tuple with two elements: data (dictionary), filename
      • output is a string or None: error message or None if no error occured
  • Define the global variables FORMAT_NAME, FORMAT_EXT, FORMAT_LOAD and FORMAT_SAVE. See the example of DICOM images support:

  • More examples of load/save functions may be found here:
