ipyfilechooser 0.3.5

Python file chooser widget for use in Jupyter/IPython in conjunction with ipywidgets

ipyfilechooser

A simple Python file chooser widget for use in Jupyter/IPython in conjunction with ipywidgets. The selected path and file are available via .selected_path and .selected_filename respectvely or as a single combined filepath via .selected. The dialog can be reset to its default path and filename by using .reset().

When a typed filename matches an existing file entry in the current folder the entry will be highlighted. If a typed filename matches a folder entry in the current view the selection button is disabled ensure the user is aware of the match. To select a folder simply leave the filename field empty.

To emphasize the risk of overwriting existing files, the selected filepath is displayed in green if the file does not exist and orange if it does.

Usage

from ipyfilechooser import FileChooser

# Create and display a FileChooser widget
fc = FileChooser('/Users/crahan/FC demo')
display(fc)

# Print the selected path, filename, or both
print(fc.selected_path)
print(fc.selected_filename)
print(fc.selected)

# Change defaults and reset the dialog
fc.default_path = '/Users/crahan/'
fc.default_filename = 'output.txt'
fc.reset()

# Shorthand reset
fc.reset(path='/Users/crahan/', filename='output.txt')

# Change hidden files
fc.show_hidden = True

# Show or hide folder icons
fc.use_dir_icons = True

# Switch to folder-only mode
fc.show_only_dirs = True

# Change the title (use '' to hide)
