My plan is to create simple todo app but in console. i want to use rust for this project. to store data, i will just use json file. example of this json file:

{
  "todos": [
    {
      "id": 1,
      "title": "Learn Rust",
      "description": "Learn rust programming language",
      "status": "incomplete"
    },
    {
      "id": 2,
      "title": "Learn JavaScript",
      "description": "Learn go programming language",
      "status": "incomplete"
    }
  ]
}

so, it will have todos array, and each todo will have id, title, description, and status.

i will create simple command line interface to interact with this json file. the commands will be:

• add todo
• list todos
• complete todo
• delete todo
• update todo
• search todo
• help

I want to create more user-friendly interface, so I will use dialoguer crate to create interactive command line interface.

my checklist for this project:

• create todo struct
• create todo status enum
• create todo service
  • add todo
  • list todos
  • complete todo
  • delete todo
  • update todo
  • search todo
• create command line interface
  • add todo - bash command: todo add --title Learn Rust --description Learn rust programming language
  • list todos - bash command: todo list --status 1
    • add more advanced print
  • complete todo - bash command: todo complete --id 1
  • delete todo - bash command: todo delete --id 1
  • update todo - bash command: todo update --id 1 --title "Learn Rust" --description "Learn rust programming language"
  • search todo - bash command: todo search --title "Learn Rust"
  • help - bash command: todo help
• create json file service
  • read json file
  • write json file
• add help command

CLI commands

I will call it from terminal like this:

$ todo add --title "Learn Rust" --description "Learn Rust programming language"
$ todo list --status "incomplete"
$ todo complete --id 1
$ todo delete --id 1
$ todo update --id 1 --title "Learn Rust" --description "Learn Rust programming language"
$ todo search --title "Learn Rust"
$ todo help

in future, need to do more fancy TUI

thanks to my memory, I will write some shortcuts for me in future
