# reddit-post-dump

## Installation
`npm install`

## Usage
`node app.js --user={username}`

### Optional parameters
* `--limit={number}`: Maximum amount posts to fetch content from
* `--sort={method}`: How posts should be sorted while fetched. This affects the `$postIndex` variable, and in combination with a `--limit` decides what posts will be included

## Configuration
The default configuration aims to be sensible, and the application may be used without any further tweaking. However, this application came to life because I was not satisfied by the organizatory facilities of similar applications, thus a multitude of options are at your disposal as described in this document.

### Patterns
Path patterns dictate where and how a file will be saved. Various variables and options are available, and you may use subdirectories divided by `/`.

### Variables
* `$postId`: The ID of the reddit post
* `$postTitle`: The title of the reddit post
* `$postUser`: The user that submitted the post, almost always equivalent to the `--user` command line argument
* `$postDate`: The submission date of the reddit post, formatted by the `dateformat` configuration described below
* `$postIndex`: The index of the post according to the sort method
* `$albumId`: The ID of the media host album
* `$albumTitle`: The title of the media host album
* `$albumDescription`: The description of the media host album
* `$albumDate`: The submission date of the media host album, formatted by the `dateformat` configuration described below
* `$itemId`: The ID of the individual image or video
* `$itemTitle`: The title of the individual image or video
* `$itemDescription`: The description of the individual image or video
* `$itemDate`: The submission date of the individual image or video, formatted by the `dateformat` configuration described below
* `$itemIndex`: The index of the individual image or video in an album, offset by the `indexOffset` configuration described below
* `$ext`: The extension of the file. Must typically be included, but may be omitted for self (text) posts on Unix systems

### Date format
Affects the representation of `$postDate`, `$albumDate` and `$itemDate` and defaults to `YYYYMMDD`. See [this documentation](https://date-fns.org/v1.29.0/docs/format) for an overview of all available tokens.

### Index offset
Arrays start at 0, but as to not tire myself out debating the matter, you may offset it my any numerical value you like. Affects the `$itemIndex` variable for album items.

### Slash substitute
The patterns represent Unix file paths, and a `/` therefore indicates a new directory. You may freely use directories in your paths, but titles or descriptions may contain a `/` that is not supposed to create a new directory. All instances of `/` in a variable value will be replaced with the configured slash substitute.
