Tabview

This project is functional but future development will be sporadic and limited. For a more fully featured CSV viewer/spreadsheet app check out the Visidata project.

The highlighted position is shown in the top-left corner of the screen; next to it are shown the contents of that cell.

Features:

• Python 3.4+
• Spreadsheet-like view for easily visualizing tabular data
• Vim-like navigation (h,j,k,l, g(top), G(bottom), 12G goto line 12, m - mark, ' - goto mark, etc.)
• Toggle persistent header row
• Sort ascending or descending by any column. Dynamically change column width and gap
• Sort in 'natural order' to improve numeric sorting
• Full-text incremental search, n and p to cycle between search results
• 'Enter' to view the full cell contents
• Yank cell contents to the clipboard
• File can be reloaded in-place if the data changes.
• F1 or ? for keybindings
• Can also use from python command line to visualize any tabular data (e.g. list-of-lists)
• See the screenshots directory for some pictures.

Requires:

• Python 3.4+
• Xsel or xclip (Optional - only required for 'yank' to clipboard)

Installation:

• pip install tabview OR
• # python setup.py install OR
• $ python setup.py install --user OR
• Archlinux AUR package

Usage:

• From command line:

  tabview <filename>
  tabview <filename> --start_pos 6,5
  tabview <filename> +6:5  (equivalent to previous usage)
  tabview <filename> --encoding iso8859-1 +6:

• From python command line to view an object

  import tabview as t
  a = [["a","b","c"], ["d","e","f"]]
  t.view(a)

• From python command line to view a file

  import tabview as t
  t.view(<filename>, start_pos=(60,40))

• Using as the pager for MySQL. Set these options in ~/.my.cnf:

  pager=tabview -d '\t' --quoting QUOTE_NONE -
  silent
  

Tests:

• python tests/test_tabview.py
