rdsline

This is a REPL for the RDS data API.

Install

Homebrew

$ brew tap hpolloni/rdsline
$ brew install rdsline

Pip

$ pip install rdsline

Usage

rdsline reads configuration from a file. The default configuration file is ~/.rdsline. You can also pass in a config file using the --config command line argument.

You can use config.yaml as a template.

| ?column?   |
|------------|
| hello      |
+------------+

This is a multi-line REPL. The end of command character is a semicolon ; or an empty line.

> select 'hello'
|
+------------+
| ?column?   |
|------------|
| hello      |
+------------+

Pipe redirection

rdsline will automatically detect when its input is a pipe. In this mode, headers are ommitted and the output is changed to TSV.

For example:

A costly way to ouput hello:

$ echo "select 'hello';" | rdsline
hello

Or most complex queries:

$ echo "select * from users;" | rdsline
