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

Usage:

    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:
