# 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/](https://racket-lang.org/)
* rodo's source code: [https://github.com/m455/rodo](https://github.com/m455/rodo)

## Downloading Racket

The Racket programming language will be needed to create a single-file executable

### 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's `raco` tool can create a single-file executable

### To download the rodo source code

1. Run `git clone https://github.com/m455/rodo`

# Getting started

This section will guide you through settig up rodo.

**Note**: This section assumes you have already [downloaded the rodo source code](#downloading-the-rodo-source-code).

## Installing rodo

Installing rodo will add a rodo executable to the `/usr/local/bin` directory. This allows users to
run rodo from any directory on their system.

**Note**: Writing to the `/usr/local/bin` directory requires root privileges.

### To install rodo

1. Change to the directory you downloaded rodo into
2. Run `sudo ./install.sh`

## Uninstalling rodo

Uninstalling rodo removes the rodo executable from the `/usr/local/bin` directory.

### To uninstall rodo

1. Change to the directory you downloaded rodo into
2. Run `sudo ./uninstall`

# Using rodo

This section will teach you how to use rodo's commands.

**Note**: This section assumes you have [installed rodo](#installing-rodo).

## Showing the help message

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

**Note**: These numbers are useful references for when you want to remove items from your list. For
more information, see the [Removing an Item from Your List](#removing-an-item-from-your-list) topic.

### 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](#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

`rodo -h`

`rodo --help`

`rodo init`

`rodo ls`

`rodo add "this is an item"`
