blossy 7.2

A lil' bud that helps you with stuff (it's a utility CLI).

🌸 Blossy CLI 🌸

A multiuse utility CLI tool developed using:

• Python
• Typer (CLI building)
• Sly Lex Yacc (parsing)

🛠 Features

• Calculate the value of an expression
• Count the quantity of characters in a text file
• Solve percentage equations
• Generate random numbers
• Stardardize the names of the files in a directory

🏁 How to Install

To install the CLI, you'll only need to have Python installed on your machine. Then, run the following command:

$ python3 -m pip install blossy

⚙️ Behavior

🧮 Calculate

To calculate the value of an expression, use the calc command. The following operators are supported:

• (expr)
• + expr
• - expr
• expr ^ expr
• expr * expr
• expr / expr
• expr + expr
• expr - expr

$ blossy calc "2*3+4^6"
4102

You can use the --visualize flag to see the steps of the calculation, illustrated using postfix notation and a stack.

$ blossy calc "2*3+4^6" --visualize

$                                                          2 3 * 4 6 ^ +₂ $

> Stack 2

$ 2                                                          3 * 4 6 ^ +₂ $

> Stack 3

$ 2 3                                                          * 4 6 ^ +₂ $

> 2 * 3 = 6

$ 6                                                              4 6 ^ +₂ $

> Stack 4

$ 6 4                                                              6 ^ +₂ $

> Stack 6

$ 6 4 6                                                              ^ +₂ $

> 4^6 = 4096

$ 6 4096                                                               +₂ $

> 6 + 4096 = 4102

$ 4102                                                                    $

> The result is 4102

⌚ Calculate Time

To calculate the value of an expression using time, use the calct command. The following operators are supported:

• (expr)
• + expr
• - expr
• expr ^ expr
• expr * expr
• expr / expr
• expr + expr
• expr - expr

$ blossy calct "1:02:00 + 12:01*2"
1:26:02

You can use the --visualize flag to see the steps of the calculation, illustrated using postfix notation and a stack.

$ blossy calct "1:02:00 + 12:01*2" --visualize

$                                                    1:02:00 12:01 2 * +₂ $

> Stack 1:02:00

$ 1:02:00                                                    12:01 2 * +₂ $

> Stack 12:01

$ 1:02:00 12:01                                                    2 * +₂ $

> Stack 2

$ 1:02:00 12:01 2                                                    * +₂ $

> 12:01 * 2 = 0:24:02

$ 1:02:00 0:24:02                                                      +₂ $

> 1:02:00 + 0:24:02 = 1:26:02

$ 1:26:02                                                                 $

> The result is 1:26:02

🔢 Count

To count the quantity of characters in a text file, use the calc command.

$ blossy count file.txt 
Character count: 58

Blossy is my favorite puppy.

Did somebody say meatloaf?

You can use the --ignore-unnec flag to ignore unnecessary whitespaces. That way, a sequence of whitespaces will be counted as only one character, and trailing whitespaces will be completely ignored.

$ blossy count file.txt --ignore-unnec
Character count: 55

Blossy is my favorite puppy. Did somebody say meatloaf?

You can also use the --ignore-ws flag to ignore all whitespaces.

$ blossy count file.txt --ignore-ws
Character count: 47

Blossyismyfavoritepuppy.Didsomebodysaymeatloaf?

📊 Percentage

To solve percentage equations, use the perc command. This command uses the formula ratio = part/whole.

$ blossy perc --whole 100 --ratio 0.25
Part: 25.0
$ blossy perc --whole 100 --part 25
Ratio: 0.25

🎲 Random

To generate a random number between two given values (inclusive), use the rand command.

$ blossy rand 1 10
2

You can specify the quantity of random numbers that'll be generated (the default is 1):

$ blossy rand 1 10 --quantity 5
2 7 1 5 1

🗂️ Standardize

To rename the files in a directory, using the format {prefix}-{id}, use the stddz command. Here's an example of how to use the command:

$ blossy stddz my-johnson nice-folder/

nice-folder/
├── my-johnson-000.png
├── my-johnson-001.png
├── my-johnson-002.png
└── my-johnson-003.png

You can use the flag --start to specify the starting number for the IDs:

$ blossy stddz my-johnson nice-folder/ --start 10

nice-folder/
├── my-johnson-010.png
├── my-johnson-011.png
├── my-johnson-012.png
└── my-johnson-013.png

You can also use the flag --digits to specify the quantity of digits that'll be used to represent the IDs (the default is 3):

$ blossy stddz my-johnson nice-folder/ --digits 2

nice-folder/
├── my-johnson-00.png
├── my-johnson-01.png
├── my-johnson-02.png
└── my-johnson-03.png
