# *httpdirectory*'s readme

This project is in an early stage of development.

## Description

This library provides a convenient way to scrape directory indexes
(like the ones created by `mod_autoindex` with apache or `autoindex`
with nginx) and get a structure that abstracts it. For instance one
may have the following website:

![Directory of cloud.debian.org/images/cloud/ website](cloud_debian.png)

The library will insert in an `HttpDirectory` structure all the
information that is to say, name, link, size and date of files
or directories. Printing it will produce the following output:

```text
https://cloud.debian.org/images/cloud/
DIR      -                    ..
DIR      -  2024-07-01 23:19  OpenStack/
DIR      -  2025-04-28 21:33  bookworm-backports/
DIR      -  2025-04-28 20:53  bookworm/
DIR      -  2025-05-12 23:57  bullseye-backports/
DIR      -  2025-05-12 23:22  bullseye/
DIR      -  2024-07-03 21:46  buster-backports/
DIR      -  2024-07-03 21:46  buster/
DIR      -  2024-04-01 14:20  sid/
DIR      -  2019-07-18 10:40  stretch-backports/
DIR      -  2019-07-18 10:40  stretch/
DIR      -  2023-07-25 07:43  trixie/
```

## Usage

First obtain a directory from an url using `HttpDirectory::new(url)`
method, then you can use `dirs()`, `files()`, `parent_directory()` or
`filter_by_name()`, `cd()`, `sort_by_name()`, `sort_by_date()`,
`sort_by_size()` to get respectively all directories, all files, the
`ParentDirectory`, filtering by the name (with a Regex), changing
directory, sorting by name, by date or by size of this `HttpDirectory`
listing entries:

```rust
  use httpdirectory::httpdirectory::HttpDirectory;
  async fn first_example() {
    if let Ok(httpdir) = HttpDirectory::new("https://cloud.debian.org/images/cloud/").await {
        println!("{:?}", httpdir.dirs());
    }
  }
```

In addition you can get some `Stats` about an `HttpDirectory` listing
using `stats` method. It will return a [Stats] structure containing
the number of directories, number of files, total apparent size, the
number of files or directories with a valid date, the number of files
or directories that has no valid dates, the number of parents (that
should always be equal or less than 1)

## Examples

You can see some examples in the example directory:
- [onedir example](examples/onedir.rs) for a small example with a
  call to the `cd()`
- [mirrors example](examples/mirrors.rs) that will try to crawl a
  list of 422 debian mirrors and print in red those that were
  possibly not correctly interpreted
- [debug me](examples/debug_me.rs) that is used in debugging
  sessions to try to improve the program by being able to interpret
  more websites
