3. cd into the rodo directory
4. Choose one of the options below for running rodo:
   • To use rodo using the Racket interpreter run: racket rodo.rkt
   • To use rodo as an single-file executable follow the steps below:
     1. Run raco exe rodo.rkt to compile rodo into a single-file executable
     2. Run ./rodo
5. (optional) Create a wrapper in your $PATH directory to run rodo from anywhere:

#!/usr/bin/env bash
racket ~/path/to/rodo.rkt "$@"

If you are using a single-file executable, create a wrapper as follows:

#!/usr/bin/env bash
~/path/to/rodo "$@"

Platforms

Below is a list of platforms that rodo can run on:

• GNU/Linux
• Windows Subsystem for Linux
• macOS (Untested)

Requirements

The following items must be installed before you can use rodo:

• Racket: https://racket-lang.org/
• rodo's source code: https://github.com/m455/rodo

Downloading the requirements

This section will guide you through downloading the required items for running rodo.

Downloading Racket

The Racket programming language will be needed to interpret or compile rodo.

To download Racket

1. run sudo apt install racket on the command line

Downloading the rodo source code

rodo's source code is needed so Racket can interpret or compile rodo.

To download the rodo source code

1. run git clone https://github.com/m455/rodo

Running rodo from any directory

This section will guide you through setting up your $PATH and adding rodo to your $PATH. This will allow you to run rodo from any directory on your system.

Setting up a $PATH

A $PATH is a directory in which you can place executable files or scripts. After placing executable files or scripts in your $PATH directory, you can then run these files or scripts from any directory on your machine.

Tip: If you have a $PATH already, then skip to Adding rodo to your $PATH

To set up a $PATH

1. Create a ~/bin/ directory for your $PATH by running mkdir ~/bin/
2. Add the ~/bin directory to your $PATH by running the following command:

echo "export PATH=~/bin:\$PATH" >> .bashrc

Adding rodo to your $PATH

After rodo has been added to your $PATH, you will be able to run it from any directory on your machine.

To add rodo to your $PATH

1. Create a file in your ~/bin/ directory with the following contents in it:

#!/usr/bin/env bash
racket ~/path/to/rodo.rkt "$@"

2. Save the file
3. Make the file executable by running chmod u+x ~/bin/name-of-your-file

Example: You create a file called rodo in your ~/bin/ directory with the following contents in it if you downloaded the rodo directory to your ~/downloads/ directory:

racket ~/downloads/rodo/rodo.rkt "$@"

You would then make the rodo file executable by running the following command:

chmod u+x ~/bin/rodo

List of commands

This section lists and describes rodo's commands.

• -h or --help displays the help message
• init creates a list file (See the config.rkt file for the default location of this file)
• ls displays your list
• add adds an item to your list
• rm removes an item from your list

Usage examples

The examples below assume that you have added rodo to your $PATH.

rodo -h

rodo --help

rodo init

rodo ls

rodo add "this is an item"

rodo add this is an item without quotation marks

rodo rm 1

Note: You may have to run rodo ls to see which number corresponds to which item in your list.

Configuring rodo

Caution: Changing the config.rkt file should be done at your own risk as it may break rodo's functionality

Settings such as the program name, directory, and the filename of the list file can be changed by editing the config.rkt file.
