## Changes

### 0.0.8

`-D` (deduplication) option was changed in the version 0.0.8. Now option is not boolean, it has several values: "disabled", "names_hashing", "content_hash".
  Long option name was changed too: now it's `deduplication-type`.


### 0.1.2

- `-l, --process-local-images` deprecated from the version 0.1.2 and will not work: local images will always be processed.
- Images with unrecognized MIME type will not be downloaded by default (use `-E` to disable this behaviour).
- New option `-P, --prepend-images-with-path` changes image output path structure. If this option is enabled,
  "remote" image path will be saved in the local directory structure.
- Code was significantly refactored.
- Some auto tests were added.


### 0.1.3

- Mostly technical fixes, necessary to work GUI tool.
- Now the tool has [Qt-based GUI](https://github.com/artiomn/mat_gui).


# Internals

Tools is a pipeline, which get Markdown form the source and process them, using blocks:

- Source download article.
- `ImageDownloader` download every image.
  Inside may be used image deduplicator blocks applied to the image.
- Transform article file, i.e. fix images URLs.
- Format article to the specific format (Markdown, HTML, PDF, etc.), using selected formatters.

`ArticleProcessor` class is a strategy, applies blocks, based on the parameters (from the CLI, for example).
