GitHub - okbob/pspg: Postgres Pager
Everybody who uses psql uses less pager. It is working well, but there is not any special support for tabular data. I found few projects, but no one was completed for this purpose. I decided to write some small specialized pager for usage as psql pager.

This pager can be used from mysql and pgcli clients too.
Main target:

- possibility to freeze first few rows, first few columns
- possibility to use fancy colors - like mcview or FoxPro

Welcome to the Click Documentation — Click Documentation (5.0)
I tried Click with Python 2.7 and it's pretty good for situations where you build commandline scripts that prompt user for input. It takes a little bit to get your head around its weird conventions to use decorators (statements starting with '@' sign):

E.g.
@click.command()
@click.option(...)

bootandy/dust: A more intuitive version of du in rust
Dust is meant to give you an instant overview of which directories are using disk space without requiring sort or head. Dust will print a maximum of 1 'Did not have permissions message'.

Dust will list the 15 biggest sub directories or files and will smartly recurse down the tree to find the larger ones. There is no need for a '-d' flag or a '-h' flag. The largest sub directory will have its size shown in red
