It's "less" for your data!
ngrid is a tool for interactive browsing large tabular datasets in a text-based terminal enviroment. ngrid is to tables as less is to text.
pip install git+https://github.com/twosigma/ngrid
ngrid command reads CSV data from a file, or from standard input if no
filename is specified, and displays it in an interactive, ncurses-based grid.
By default, ngrid loads rows incrementally from its input, so that it can quickly present the beginning of a long file or stream without loading the entirety of the data. (The total line count in the status bar shows "+" to indicate that more lines are available but have not been read.) It does however store all data it has already seen, so that you can always scroll backward.
ngrid instead loads the entire input into a
Pandas dataframe at startup. This may result in better guesses for column
display parameters, such as width and decimal precision.
In the interactive display, press
h to show usage help; press
q to exit.
ngrid.grid.show_dataframe() to show a Pandas dataframe. As with the
command line program, press
q to exit the interactive display and return
ngrid works only in an ncurses-compatible terminal; it won't work in IPython Notebook, most IDEs, or similar graphical environments.
