## Introduction <a class="anchor" id="intro"></a>

**pysentation** is a **CLI** for displaying Python **presentations**.

**pysentation**, by taking a **Python file** written with simple but specific **rules**, can **convert** the contents of the Python file into a **slide show** and display it.

For more information, I suggest you [start here](#usage).

## Installation <a class="anchor" id="install"></a>
You can use **pip** to install:
```
python3 -m pip install pysentation
```

And also to **upgrade**:
```
python3 -m pip install --upgrade pysentation
```

If there is a **problem**, install the **requirement packages** separately as below and then try again.

First, download the `requirements.txt` file with **curl**:
```
curl -o requirements.txt https://raw.githubusercontent.com/mimseyedi/pysentation/master/requirements.txt
```

Then install the **packages** in the `requirements.txt` using **pip**:
```
python3 -m pip install -r requirements.txt
```

You can still do it **yourself** without needing the `requirements.txt` file:
```
python3 -m pip install rich==13.4.1 getkey==0.6.5 click==8.1.3
```

## How to use pysentation? <a class="anchor" id="usage"></a>
There are two ways to use pysentation!

The first way is the **classic** way of reading the **document**. You may be surprised, but many people live with documents and love to read them. That's why this possibility is completely available for people who belong to this category, and if you like documents, it's better to continue right now.

But there is a **second way**! What could be better than **understanding** how to work with a program **while** you are **inside** it and **using** it? I like documents, but **believe** me, this method is much more **interesting**! Let **pysentation** introduce **itself** to you.

There are two very **simple** steps for this.

First of all, **download** this pysentation file with the help of **curl**:
```
curl -o train_journey.py https://raw.githubusercontent.com/mimseyedi/pysentation/master/docs/guide/train_journey.py
```

Then after you install **pysentation**, run the file you downloaded with the **pysentation** command:
```
pysentation train_journey.py
```

## pysentation file <a class="anchor" id="pysentation_file"></a>
To use **pysentation**, you first need a **pysentation file**. The pysentation file is actually a **Python file** or a converted file with (.pysent) suffix. But it follows **rules** that can be converted into a **slideshow** and interpreted by **pysentation CLI**.

[↑ Table of contents](#contents)

## pysentation scope <a class="anchor" id="scope"></a>
A **pysentation** file consists of a **pysentation** scope. Specifying the scope of the pysentation is mandatory so that the **interpretation** can be done correctly:
```python
#pysentation{
...
...
#pysentation}
```

This **range** specifies the **presentation environment**. All pysentation **commands** and attributes in a **python file** are a python **comment**, but they have **special names** so that they can be **interpreted** correctly.

[↑ Table of contents](#contents)

## Slides <a class="anchor" id="slides"></a>
Each **pysentation** consists of one or more **slides**. To make a **slide**, just do the following:
```python
#pysentation{

#>slide
...

#pysentation}
```
Now, after `#>slide`, you can **define** slide **properties** and slide **elements**, which we will explain below.

You can also define **several** slides in **one scope**:
```python
#pysentation{

#>slide
...

#pysentation}
```

[↑ Table of contents](#contents)

## Properties <a class="anchor" id="props"></a>
Each **slide** has **properties** that can **change** the presentation of the slide. These properties are **listed** in the table below, which I will examine one by one in the following:

|Property| Action                                                                                                                                     | Definition form        |Default value|
|---|--------------------------------------------------------------------------------------------------------------------------------------------|------------------------|---|
|Title| You can change the title of the slide with this property.                                                                                  | #-title: Slide's Title |none|
|Title align| You can change the slide title align with this property.                                                                                   | #-title_align: left    |center|
|Color| You can change the color of the slide with this property.                                                                                  | #-color: green         |default|
|Theme| You can change the theme of syntax highlighters of the slide with this property.                                                           | #-theme: github-dark   |gruvbox-dark|
|Expand| With this property, it can be specified that the slide box is the same width as the screen or stretched to the size of the slide elements. | #-expand: True         |True|
|Interpretable| With this property, it is possible to determine whether the codes inside the slide are interpreted and their output is displayed or not.   | #-interpretable: False |True|

**Note: Properties are case sensitive and must be written as defined.**

## Title <a class="anchor" id="title"></a>
This feature refers to the slide:
```python
#pysentation{

#>slide
#-title: First slide

#pysentation}
```

Output:
```
┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ First slide ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃                                                                                             ┃
┃                                                                                             ┃
┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1/1 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛
```

[↑ Table of contents](#contents)

## Title align <a class="anchor" id="title_align"></a>
This property specifies the **location** of the slide **title** and it can be defined in **three** modes: `right`, `center` and `left` **(The default value is `center`)**:
```python
#pysentation{

#>slide
#-title: First slide
#-title_align: left

#pysentation}
```

Output:
```
┏━ First slide ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃                                                                                             ┃
┃                                                                                             ┃
┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1/1 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛
```

## Color <a class="anchor" id="color"></a>
This property refers to the **color** of the slide and its **components** **(The default value is equal to `default` or color of the terminal font)**:
![](https://raw.githubusercontent.com/mimseyedi/pysentation/master/docs/images/color-property.png)

Click <a href="#colors">here</a> to view the available colors.

[↑ Table of contents](#contents)

## Theme <a class="anchor" id="theme"></a>
This property refers to the **theme** of the **syntax highlighters** in the slide **(The default value is `gruvbox-dark`)**:
![](https://raw.githubusercontent.com/mimseyedi/pysentation/master/docs/images/theme-property.png)

Click <a href="#themes">here</a> to view the available themes.

[↑ Table of contents](#contents)
## Expand <a class="anchor" id="expand"></a>
By setting this property to `True` or `False`, you can specify whether the **size** of the slide is the same as the size of the **screen** or the size of the **elements** inside it **(The default value is `True`)**:

```python
#pysentation{

#>slide
#-expand: False

#pysentation}
```

[↑ Table of contents](#contents)

## Interpretable <a class="anchor" id="interpretable"></a>
If this property is `True`, all the **codes** inside a slide will be **interpreted separately** with the help of **Python interpreter** and the **output** will be **displayed** under them in a **separate box**. But if its value is `False`, it will not do this **(The default value is `True`)**:

```python
#pysentation{

#>slide
#-interpretable: False

#pysentation}
```

[↑ Table of contents](#contents)

## Comments <a class="anchor" id="comments"></a>
The **comments** are actually the explanations that we can see in the **slides**. The content of the comments can be **anything** and can be given different modes according to the **styles** of the <a href="https://github.com/Textualize/rich">rich</a> module.

Comments start with `#:`: 
```python
#pysentation{

#>slide
#-title: Wonderful slide
#: Hello!, this is my wonderfull slide.
#: Yes, you see right! I am a comment that can be displayed!
#: Also, I can make the word [yellow]"can"[/yellow] yellow like this.

#pysentation}
```

Output:

## Codes <a class="anchor" id="codes"></a>
The codes have no **special characteristics** and can be easily written and **interpreted** if needed:
```python
#pysentation{

#>slide
#-title: Legal age
#: Here is a simple example of if and else statements:
age = 19
if age >= 18:
    print("Access Granted!")
else:
    print("Access Denied! Underage")
    
#pysentation}
```

Output:
```

Even if the code **raises** an **exception**, the **error message** will be displayed:
```python

## Lines <a class="anchor" id="lines"></a>
**Lines** are the simplest **elements** of slides. The task of these line elements is to **draw** a **horizontal** line to **separate** the screen, and its sign is `#_line`.

```python
#pysentation{

#>slide
#-title: About lines with merge sort
#-interpretable: False

#:Create sub_array2 ← A[start..mid] and sub_array2 ← A[mid+1..end]
def mergeSort(arr):
 mid = len(arr)//2
 sub_array1 = arr[:mid]
 sub_array2 = arr[mid:]
#_line
#:Sort the two halves:
 mergeSort(sub_array1)
 mergeSort(sub_array2)
 # Initial values for pointers that we use to keep track of where we are in each array
 i = j = k = 0
#_line
#:Until we reach the end of either start or end, pick larger among elements start and end and place them in the correct position in the sorted array:
 while i < len(sub_array1) and j < len(sub_array2):
 if sub_array1[i] < sub_array2[j]:
 arr[k] = sub_array1[i]
 i += 1
 else:
 arr[k] = sub_array2[j]
 j += 1
 k += 1
#_line
#:When all elements are traversed in either arr1 or arr2, pick up the remaining elements and put in sorted array:
 while i < len(sub_array1):
 arr[k] = sub_array1[i]
 i += 1
 k += 1

while j < len(sub_array2):
 arr[k] = sub_array2[j]
 j += 1
 k += 1
#pysentation}
```

Output:
```

## Slideshow screen <a class="anchor" id="slideshow"></a>
The **slideshow screen** is the **main** screen for displaying slides. When we have prepared a **pysentation file**, we can **run** the slides with the help of the following **command** and **manage** it with the help of special **keys**:
```
pysentation my_file.py | my_file.pysent
```

## Colors and themes <a class="anchor" id="colors_and_themes"></a>
There are many **colors** and **themes** to use in **pysentation** that all follow the <a href="https://github.com/Textualize/rich">rich</a> module. They are mentioned below.

[↑ Table of contents](#contents)

## Colors <a class="anchor" id="colors"></a>
This is a list of **16** main colors that you can **use** in pysentation. You can see the information of more diverse colors from <a href="https://rich.readthedocs.io/en/stable/appendix/colors.html#appendix-colors">here</a>.

**Note: To use any color, you can mention its name, number, hex code and rgb number.**
