listpick

listpick is a powerful TUI data tool for viewing, editing and operating upon tabulated data; can be used to build TUI applications, generate data columns, or function as a command-line utility.

NOTE: listpick is still in development.

Quickstart

Install listpick:

python -m pip installl "listpick[full]"

Create a Picker:

from listpick.listpick_app import Picker, start_curses, close_curses

stdscr = start_curses()

x = Picker(
    stdscr,
    items=[
        ["row zero column zero", "row zero column one"],
        ["row one column zero", "row one column one"]
    ],
    header=["H0", "H1"],
    cell_cursor=True,
)
x.run()

close_curses(stdscr)

Overview

The application allows you to:

• Select multiple items from different file types and input streams
• Delete individual items
• Highlight specific items for quick selection
• Filtering: supports regular expressions for row- and column-based filtering.
• Searching: supports regular expressions for row- and column-based searching.
• Sort data based on specified columns and sort-type
• Save and load data.
• Copy/paste selections to clipboard
• Generate rows from a list of commands in an input.toml file.

Examples

listpick as a command-line tool

listpick can be used as a command-line tool for tabulating command outputs:

df -h | listpick --stdin

Applications

Aria2TUI

Aria2TUI: TUI client for the aria2c download utility.

lpfman

lpfman: Terminal file manager with extensive column support.

Data generation from toml file

listpick -g ./listpick/examples/data_generation/video_duplicates.toml

• From the list of commands in the toml file we generate the properties we will use to identify the duplicates.

• In the example file we set the directory and get the files with a simle eza (ls) command. We could also use find or cat from a list of files.

• We get the SHA1 hash to identify identical files; we also get the size, duration, resolution, and bitrate so that we can identify a video duplicate that may have the same duration but a lower resolution.

Description

Key Features:

1. File Input Support:

listpick -i ~/items.csv

• Text files (TSV, CSV)
• JSON
• XLSX
• ODS (OpenDocument Spreadsheet)
• Pickle

2. Generate data based on an toml file with relevant commands to generate the rows.

listpick -g ./examples/data_generation/video_duplicates.toml

• See ./examples/

3. Highlighting:

• Highlight specific strings for display purposes.
• E.g., when we search for a string we will highlight strings in the rows that match the search.

4. Filtering and Sorting:

• Apply custom filters and sort criteria on the fly

5. Modes:

• Default modes are supported so that a certain filter/search/sort can structure the data in a way that is easy to move between.

6. Options:

• Along with returning the selected rows, the user can also return options.
• Input field with readline support
• Options select box

7. Colour themes:

• Several colour themes are available

8. Copy rows:

• 'y' to copy rows in various formats: CSV, TSV, python list

9. Save data:

• Data can be saved so that it can be loaded with the -i flag.
• This is very helpful if your data generation takes a long time.

10. Customisable keybinds:

• The Picker object takes a keys_dict variable which allows all keys to be customised. Default keys can be seen in src/listpick/ui/keys.py.
• Also allows the restriction of certain functions by not assigning a key.

11. Dynamic or manual refresh of data:

• If a refresh_function is passed with auto_refresh=True then listpick will automatically refresh the data. - If a refresh_function is passed then one can also manually refresh by pressing f5.

12. Notifications.

• Supports notifications upon certain events

13. Visual options

• Display/hide title.
• Display/hide footer with selection information
• Display/hide columns
• Display/hide highlights
• Option to centre in cells, centre in terminal and centre rows vertically.

14. Change settings on the fly.

• Press '~' to see list of display settings or press '`' to enter a command to change display settings.
• Change visual options
  • Cycle through themes
  • Centre data in cells or centre rows vertically
  • Show/hide the footer
  • Show/hide a specific column.
  • Select a column
• Toggle auto-refresh
• Toggle highlights

15. Pipe the data from the selected rows in the focussed column to a bash command ('|')

• By default when you press '|' it will fill the input field with xargs . You can remove this if you like (^U).
• For example, if you run xargs -d '\n' -I {} notify-send {} to this it will display notifications containing the data from the current column
• Useful for:
  • Opening files with a specific application xargs -d \n -I{} mpv {} will open the files in mpv
  • Dumping data. xargs -d \n -I{} echo {} > ~/stuff.txt
