Quick start

Note - This section is for users who are familiar with git, a Unix-like command line environment, or scripting.

1. Make sure Racket is installed
2. git clone https://github.com/m455/rodo into a directory of your choice
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 "$@"

Getting started

This readme will guide you through downloading, setting up, and using the rodo list manager. This readme is intended for people who spend a lot of their time on the command line and want a minimal list manager.

• Tip- Tips signify an alternate procedure for completing a step
• Caution - Cautions signify that damage may occur
• Example - Examples provide a visual reference of how a procedure would be carried out in the real world
• Inline code - Inline code signifies package names, filenames, or commands
• Code block - Code blocks signify file contents

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 downloaded and installed before you can use rodo:

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

Downloading Racket

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

To download and install 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

Using rodo

This section will guide you the various commands that rodo can use. This section assumes you know how to run either the rodo.rkt using the Racket interpreter (racket rodo.rkt) or you have created an executable using raco exe rodo.rkt.

Showing the help message

The help message will provide a list of available commands. This is useful in case you forget the name of a comamnd or how to use a command.

To show the help message

1. Run rodo -h

Initializing rodo

Before using rodo, you must initialize rodo. Initializing will allow you to save your list to a text file for later access.

To initialize rodo

1. Run rodo init

Displaying your list

Displaying your list will allow you to view items you have added to your list. You will notice numbers beside the items in your list. These numbers are for references when removing items. See the Removing an Item from Your List topic for more information.

To display your list

1. Run rodo ls

Adding an item to your list

Adding an item to your list will save it to a text file to access later.

To add an item to your list

1. Run rodo add "this is an example of an item using double quotation marks"

Note - The double quotation marks are optional, but recommended

Removing an item from your list

When removing an item from your list, you can reference the numbers beside each item when Displaying Your List. You can use these numbers when removing an item from your list.

To remove an item from your list

1. Run rodo rm 1

Note 1 - The "1" in the procedure above will remove the first item in your list.

Note 2 - You may need to run rodo ls first to see which numbers correspond with which item in your list.

Configuring rodo

You can configure rodo's settings, such as the location of the list file, and command names.

To configure rodo

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

1. Edit the config.rkt file

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.
