Todo List (Command Line Interface based)

A simple CLI based todo list command-line (CLI) program that lets you manage your todos.

Specification

  1. The app can be run in the console with ./todo.

  2. The app reads from and write to a data.txt text file. Each todo item occupies a single line in this file. Here is an example file that has 2 todo items.

water the plants
change light bulb
  1. When a todo item is completed, it is removed from data.txt and increases value in count.txt text file. This file has a different format:

Usage

Use the command "g++ todo.cpp" to generate the output file

1. Help

Executing the command without any arguments, or with a single argument help prints the CLI usage.

$ ./todo help
Usage :-
$ ./todo add "todo item"  # Add a new todo
$ ./todo ls               # Show remaining todos
$ ./todo del NUMBER       # Delete a todo
$ ./todo done NUMBER      # Complete a todo
$ ./todo help             # Show usage
$ ./todo report           # Statistics

2. List all pending todos

Use the ls command to see all the todos that are not yet complete. The most recently added todo should be displayed first.

$ ./todo ls
[2] change light bulb
[1] water the plants

3. Add a new todo

Use the add command. The text of the todo item should be enclosed within double quotes (otherwise only the first word is considered as the todo text, and the remaining words are treated as different arguments).

$ ./todo add "the thing i need to do"
Added todo: "the thing i need to do"

4. Delete a todo item

Use the del command to remove a todo item by its number.

$ ./todo del 3
Deleted todo #3

Attempting to delete a non-existent todo item should display an error message.

$ ./todo del 5
Error: todo #5 does not exist. Nothing deleted.

5. Mark a todo item as completed

Use the done command to mark a todo item as completed by its number.

$ ./todo done 1
Marked todo #1 as done.

Attempting to mark a non-existed todo item as completed will display an error message.

$ ./todo done 5
Error: todo #5 does not exist.

6. Generate a report

Use the report command to see the latest tally of pending and completed todos.

$ ./todo report
yyyy-mm-dd Pending : 1 Completed : 4
