## Types data

Here you can find a data types that used in mangadex-downloader path placeholders

### string type data

It's a text.

The string type data follows python f-string (formatted string). 
You can read more about it [in here](https://docs.python.org/3/library/string.html#format-specification-mini-language)

### integer type data

It's a negative or positive number

### array type data

It's a list of data, 
you can access a data by giving index position.

```{note}
You may see additional data type inside of a bracket

Like this one: `array[string]`

This means inside the array is an list of strings.
```

For example:

```shell
# Let's say you want to get alternative title
# You can do this by accessing `alternative_titles` in manga placeholder
# This will get alternative title in position 0 of an list
mangadex-dl "URL" --path "/home/mymanga/{manga.alternative_titles[0]}"
```

### ArrayModified type data

Same as `array` data type, but it has additional attributes

- first
- last

These attributes is equals to accessing array with index `0` or `-1`.

Let me give you an example:

```shell
# Doing this
mangadex-dl "URL" --filename-volume "Vol. {volume} (Ch. {volume.chapters.first.chapter} - Ch. {volume.chapters.last.chapter})"

# Is equal to
mangadex-dl "URL" --filename-volume "Vol. {volume} (Ch. {volume.chapters[0].chapter} - Ch. {volume.chapters[-1].chapter})"
```

I know some of you asking "But why ? why you did this ?"

Because it looks elegant and clean 😂👌.

## Examples

```shell
# This manga will be saved in directory
# "/home/verysus/manga/Some manga title/English"
# with cbz format and custom filename with placeholders
mangadex-dl "URL" -f cbz --path "/home/verysus/manga/{manga.title}/{language.full}" --filename-chapter "Vol. {chapter.volume} Ch. {chapter.chapter}{file_ext}"
```
