## Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

### Prerequisites

#### Python

You will need Python 3 to use this module

```bash
# vermin output
Minimum required versions: 3.4
Incompatible versions:     2
```

## Installing

### Option 1: From PyPI

```bash
pip install --upgrade miko
```

### Option 2: From Git

```bash
pip install --upgrade git+https://github.com/Animenosekai/miko
```

You can check if you successfully installed it by printing out its version:

```bash
$ python -c "import miko; print(miko.__version__)"
# output:
miko v1.0
```

```bash
$ miko --version
# output:
miko v1.0
```

## Purpose

This new style aims at bringing an ease of use for both humans and computers.

It also helps me get concise while writing docstrings as I tend to use different styles even within a same file.

## Style

Miko defines a new way of documenting your source code.

You will here learn the different sections of your documentation string.

### Outline

The *Miko* way of documenting stuff is by using Markdown in your documentation and following the rules below.

#### Start

When you want to document the object, you need to start the docstring with 3 quotation marks, preferably double quotation marks.

You also need to add a line break and pad the whole documentation to line up with the start of the object name.

> Example: we are using 3 double quotation marks, and we start where the object name starts after a line break.

```python
def func():
    """
    It needs to start here

    Here we continue the documentation string
^^^^
(do not use this space)
    """
    pass
```

#### End

The documentation string ends when 3 quotation marks (the same as the beginning ones) are added after the padding.

### Description

After starting the documentation string, you can add a description for your object as a normal string.

There is not much styling or rules to follow since all the content outside any section is considered part of the description.

> Example: We are giving a description of the function at the start, but also at the end.

```python
def func():
    """
    Hello, this is a description.

    Returns
    ----------
    bool
        The result of the function.

    But this is also part of the description.
    """
```

### Parameters

You can define what are the different parameters/arguments the callable object is taking.

To start explaining the different parameters, you need to use the `Parameters` section name, followed by a line-break and at least 3 hyphens.

A single parameter element is defined by a name, followed by some options. And, on a new line, with a left padding, its description.

> Example

```python
def func(a, b: int, c = ""):
    """
    Parameters
    ----------
    a: bool
        this is the first argument
    b: int | float, default = 1.2
        this is the second argument
    c: str, optional
        this is the third argument
        it can have multiple lines
    """
```

> Aliases: `Parameters`, `Parameter`, `Params`, `Parm`, `Arguments`, `Argument`, `Args`, `Arg`

#### The options

You can specify options for each parameter.

The options are separated from the parameter name using a colon and a space.

Each option is separated by a comma.

- `<type>` : defines the type of the parameter.
- `optional` : defines a parameter as being optional, without needing to specify its default value. *(useful with keyword arguments for instance)*
- `default` : defines a parameter as being optional, by giving it a default value.
- `deprecated` : when a parameter is deprecated.

##### Types

Types can be defined by giving the element class name or *dot notation* path.

> Example: `str`, `translatepy.language.Language`

You can specify multiple types using the vertical bar separator.

> Example: `int | float`

##### Default

You can define a default value using an equal sign.

> Example: `default = 1`, `default=True`

### Returned Value

You can define what are the values returned by a callable object using the `Returns` section.

Each returning element is explained with the following rules: the type of the value and a description with a left-padding on a new line.

> Example

```python
def func():
    """
    Returns
    -------
    int
        the number returned
    str
        if it is a string returned
    list[int, str]
        if it's a list of both
    translatepy.Language
        using dot notation
    """
```

> Aliases: `Returns`, `Return`, `Returning`

### Example

You can give examples of your code, writing them as you would in a Python REPL.

```python
def func(a = False):
    """
    Example
    -------
    >>> func()
    "It is false"
    >>> func(True)
    "It is true"
    # when using something other than a boolean
    >>> func(1)
    2
    """
```

You can use `# comments` to explain your example.

> Aliases: `Examples`, `Example`

### Exceptions

You can inform the users about any exception/error your callable might be raising using the `Raising` section.

Like the `Returns` section, you need to give the name of the exception and then a description of why it would raise this exception and the special attribute the exception might have on a new line, left-padded.

> Example

```python
def func():
    """
    Raises
    ------
    ValueError
        If there is an error with the value
    """
```

> Aliases: `Raises`, `Raise`, `Raising`, `Exceptions`, `Exception`, `Errors`, `Error`

### Warnings

You can give warnings to the user using the `Warning` tag.

You just need to put `Warning`, followed by a colon, a space and the warning itself.

> Example

```python
def func():
    """
    Warning: This is a serious warning

    ...description...

    Warning: Another warning
    """
```

> Aliases: `Warnings`, `Warning`

<br>

> **Note**  
> Warnings are part of the description

### Notes

If you only want to notify the user about something, you can use the `Note` tag.

You just need to put `Note`, followed by a colon, a space and the note itself.

> Example

```python
def func():
    """
    Note: Yup, that's true

    ...description...

    Note: Another note
    """
```

> Aliases: `Notes`, `Note`, `See Also`, `Information`

<br>

> **Note**  
> Notes are part of the description

### Change log

You can inform the users about how the object got modified over time using the `Changelog` section.

Like the `Returns` section, you need to give the name of the version it got changed on and then a description of how it changed on a new line, left-padded.

> Example

```python
def func():
    """
    Changelog
    ---------
    1.4
        New default string
    0.6
        Raises ImportError instead of RuntimeError
    """
```

> Aliases: `Changelog`, `Changes`

### Deprecation Notice

To add a deprecation notice to your object, you can add `! DEPRECATED !` at the beginning of the docstring.

It must be the first thing (aside from whitespace) of the docstring.

> Example: At the very beginning of the docstring

```python
def func():
    """! DEPRECATED !
    This is a cool function.

    Changelog
    ---------
    1.5
        Added a deprecation notice, with the intention of the function being removed on the next major version.
    """
```

> Example: With a slight variation

```python
def func():
    """
    !DEPRECATED!

    This is a cool function.
    """
```
> Aliases: `Deprecated`, `Deprecation`, `Deprecate`, `Deprecation Notice`

### Copyright

You can add copyright/authors of the code using the `Copyright` section.

Like the `Returns` section, you need to give the name of the author and then a description of what they did on a new line, left-padded. The description could include stuff like the year they worked on the code, what they did, etc.

> Example

```python
def func():
    """
    Copyright
    ---------
    Animenosekai
        The initial author
    Some other dev
        A very cool collaborator
    """
```

> Aliases: `Copyrights`, `Copyright`, `Authors`, `Author`

## Usage

*Here, there will be the Python API Reference.*

### On Python

Two objects are exposed through the Python API

#### The `Docs` object

You can use the `Docs` object by passing a docstring and an optional function signature.

> Example

```python
from miko import Docs

parsed = Docs(
    """
    Hello

    Note: this is a test

    Changelog
    ---------
    1.0
        Adding this docstring
    """
)
```

##### Parameters

| Name | Description | Type | Default |
|------|-------------|------|---------|
| `docs` | This is the docstring to parse | str | `` |
| `signature` | The function signature to get the additional parameters from | inspect.Signature | None |
| `noself` | If you don't want to use the `self` parameter from the signature, useful for class methods | bool | False |

##### Attributes

- **`description`**

> str

The description of the object in the docstring.

- **`parameters`**

> List[Parameter]

This contains the different parameters found on the function and on the docstring

The attribute returns a `List` object with `Parameter` objects.

A `Parameter` object has the following attributes:

| Attribute | Description | Type |
| --------- | ----------- | ---- |
| `name` | The name of the parameter | str |
| `content` | A list of strings, each one being a line of the parameter description | list[str] |
| `deprecated` | If the parameter is deprecated | bool |
| `optional` | If the parameter is optional | bool |
| `default` | The default value for the parameter, if it has any | str, Any |
| `types` | A list of types the parameter can be | list[str, Any] |

- **`returns`**
- **`raises`**
- **`changelog`**
- **`copyright`**

> List[ListElement]

They all share the same schema, a `List` object with `ListElement` objects.

A `ListElement` object has the following attributes:

| Attribute | Description | Type |
| --------- | ----------- | ---- |
| `name` | The name of the element | str |
| `content` | A list of strings, each one being a line of the element description | list[str] |

- **`example`**

> Example

The `example` attribute contains any example code the docstring might contain.

- **`warnings`**
- **`notes`**

> list[str]

The `warnings` and `notes` attributes are just a list of warnings or notes it could have find in the description.

- **`deprecated`**

> bool

If the object is marked as deprecated

##### Methods

- **`dumps`**

This function lets you dump the documentation string to the cleanest format possible, using all of the information the current `Docs` has.

The optional `indent` parameter (which defaults to 4), lets you choose the indentation level of the output.

It returns a string with the output documentation string.

- **`as_dict`**

The `as_dict` function lets you convert the `Docs` object to a dictionary.

It takes an optional `camelCase` parameter (which defaults to False), which lets you have a camelCased and JSON friendly dictionary returned.

#### The `Function` object

The `Function` object lets you get information about a function.

On top of the docs, it also lets you retrieve easily its source code filename, line number, name, the different local variables, the parameters, the return annotation, and its name.

### Using the CLI

`Miko` also has a CLI, which you can use to get information about a docstring or clean a docstring.

```swift
🧃❯ miko -h                                                                                                     
usage: miko [-h] [--version] {info,clean} ...

See how to use a Python object at a glance!

positional arguments:
  {info,clean}   Actions
    info         Retrieve info on the given docstring
    clean        Clean the docstring

optional arguments:
  -h, --help     show this help message and exit
  --version, -v  show program's version number and exit
```

#### `miko info`

You can get information about the docstring using `miko info`.

##### Arguments

| Name | Aliases | Description | Type | Default |
|------|---------|-------------|------|---------|
| `--text` | `-t` | The docstring to parse | str | `` |
| `--file` | `-f` | The file to parse | Path(str) | `` |
| `--indent` | `-i` | The indentation for the JSON result | int | 4 |
| `--noself` | `` | Ignoring the "self" parameter from signatures. (useful for class methods) | (flag) | False |

It will return information about the given docstring (if `--text` is given) or a list of information about the different docstrings found in the given file (if `--file` is given).

It prints a JSON string.

#### `miko clean`

You can clean a docstring using `miko clean`.

##### Arguments

| Name | Aliases | Description | Type | Default |
|------|---------|-------------|------|---------|
| `--text` | `-t` | The docstring to clean | str | `` |
| `--file` | `-f` | The file to clean | Path(str) | `` |
| `--indent` | `-i` | The indentation for the cleaned result | int | 4 |
| `--noself` | `` | Ignoring the "self" parameter from signatures. (useful for class methods) | (flag) | False |
| `--output` | `-o` | The file to output the cleaned result to | Path(str) | None |

It will clean the given docstring (if `--text` is given) or it will return the file with the docstrings cleaned (if `--file` is given).

It prints the cleaned output.

### Using the VS Code Extension

You can also use the `Miko` extension for Visual Studio Code.

It lets you format your files instantly using the command palette.

![VS Code Command Palette](./assets/docs/vscode_command_palette.png)

You can add the `--noself` flag using the `Noself` setting in the Settings (UI) or the `miko-docs.noself` settings (JSON).

#### Installing the extension

Go to [https://marketplace.visualstudio.com/items?itemName=Animenosekai.miko-docs](https://marketplace.visualstudio.com/items?itemName=Animenosekai.miko-docs) to download the published version from the marketplace.
