I would like to add some interactive capability to a python CLI application I’ve writen that stores data in a SQLite3 database. Currently, my app reads-in a certain type of file, parses and analyzes, puts the analysis data into the db, and spits the formatted records to stdout (which I generally pipe to a file). There are on the order of a million records in this file. Ideally, I would like to eliminate that text file situation altogether and just loop after that “parse and analyze” part, displaying a screen’s worth of records, and allowing the user to page through them and enter some commands that will edit the records. The backend part I know how to do.
Can anyone suggest a good starting point for creating that pager frontend either directly in the console (like the pager “less”), through ncurses, or some other system?
You might want to take a look at urwid. It is a console user interface library for Python. The examples should be more than enough to convince you that this is what you want, if you really want to go text-console UI.
I’d use something like pygtk instead though.
