## :hand: Intro

Type English for logic symbols! This is a simple string replacement program dedicated for typing logic symbols. Since those symbols are not on our keyboard, typing them is a little bit cumbersome. This tool allows you to type English to get them. Have fun!

## :information_source: Usage

Input your FOL sentence in the box of **string**. If you want to type a specific logic symbol at some point of your FOL sentence, just type its corresponding tag (uppercase English words) instead, and keep everything else the same. 

| Logic Symbol |  Tag  |
| :----------: | :---: |
|      ∧       |  AND  |
|      ∨       |  OR   |
|      ¬       |  NOT  |
|      ⊕       |  XR   |
|      →       | IMPLY |
|      ↔       | EQUIV |
|      ∀       |  ALL  |
|      ∃       | EXIST |

The translation is **real-time**. After your input is finished, you can directly copy the result in the box of **output**.

Note that you can input **multi-line** sentences!

You will find five examples of using them below the boxes.

## :scroll: Source Code

Very simple. The core of it is just like:

```python
def logic(string: str):
    for word, symbol in logic_dict.items():
        string = string.replace(word, symbol)
    return string
```

where `logic_dict` stores all the translation between tags and logic symbols. The user interface is built with [Gradio](https://gradio.app/).

## :warning:Notice

Please don’t include the ==exact same uppercase spelling== of any of the tags in your FOL sentence if you don’t mean it, or the program will replace them without thinking. For example, it your input sentence is: **WALL(berlin wall)** meaning “berlin wall is a wall”, the program output would be **W∀(berlin wall)** with the **ALL** after **W** replaced by **∀**, which is not what you want.
