# Changelog

All notable changes to this project will be documented in this file. The format
is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

This project has its own custom versioning scheme. Version numbers consist of
three parts (e. g. `3.1.5`).
- The first number is increased on major rewrites or changes. What classifies as
  a major change is up to the maintainers. This is pretty rare and a PFERD
  version 4 should hopefully not be necessary.
- The second number is increased on backwards-incompatible changes in behaviour.
  This refers to any change that would make an existing setup behave differently
  (e. g. renaming options or changing crawler behaviour). If this number is
  increased, it may be necessary for you to adapt your own setup.
- The third number is increased on backwards-compatible changes (e. g. adding
  new options or commands, changing documentation, fixing bugs). Updates that
  only increase this number should be safe and not require manual intervention.

We will try to correctly classify changes as backwards-compatible or
backwards-incompatible, but may occasionally make mistakes or stumble across
ambiguous situations.

## Unreleased

### Added
- `--skip` command line option
- Support for ILIAS booking objects

### Changed
- Using multiple path segments on left side of `-name->` now results in an
  error. This was already forbidden by the documentation but silently accepted
  by PFERD.
- More consistent path printing in some `--explain` messages

### Fixed
- Nondeterministic name deduplication due to ILIAS reordering elements

## 3.1.0 - 2021-06-13

If your config file doesn't do weird things with transforms, it should continue
to work. If your `-re->` arrows behave weirdly, try replacing them with
`-exact-re->` arrows. If you're on Windows, you might need to switch from `\`
path separators to `/` in your regex rules.

### Added
- `skip` option for crawlers
- Rules with `>>` instead of `>` as arrow head
- `-exact-re->` arrow (behaves like `-re->` did previously)

### Changed
- The `-re->` arrow can now rename directories (like `-->`)
- Use `/` instead of `\` as path separator for (regex) rules on Windows
- Use the label to the left for exercises instead of the button name to
  determine the folder name

### Fixed
- Video pagination handling in ILIAS crawler

## 3.0.1 - 2021-06-01

### Added
- `credential-file` authenticator
- `--credential-file` option for `kit-ilias-web` command
- Warning if using concurrent tasks with `kit-ilias-web`

### Changed
- Cookies are now stored in a text-based format

### Fixed
- Date parsing now also works correctly in non-group exercises

## 3.0.0 - 2021-05-31

### Added
- Proper config files
- Concurrent crawling
- Crawl external ILIAS links
- Crawl uploaded exercise solutions
- Explain what PFERD is doing and why (`--explain`)
- More control over output (`--status`, `--report`)
- Debug transform rules with `--debug-transforms`
- Print report after exiting via Ctrl+C
- Store crawler reports in `.report` JSON file
- Extensive config file documentation (`CONFIG.md`)
- Documentation for developers (`DEV.md`)
- This changelog

### Changed
- Rewrote almost everything
- Better error messages
- Redesigned CLI
- Redesigned transform rules
- ILIAS crawling logic (paths may be different)
- Better support for weird paths on Windows
- Set user agent (`PFERD/<version>`)

### Removed
- Backwards compatibility with 2.x
- Python files as config files
- Some types of crawlers

Add 'skip' option to crawlers 2021-06-04 18:33:02 +02:00			`### Added`
			- `skip` option for crawlers
Overhaul transform logic -re-> arrows now rename their parent directories (like -->) and don't require a full match (like -exact->). Their old behaviour is available as -exact-re->. Also, this change adds the ">>" arrow head, which modifies the current path and continues to the next rule when it matches. 2021-06-09 17:42:38 +02:00			- Rules with `>>` instead of `>` as arrow head
			- `-exact-re->` arrow (behaves like `-re->` did previously)
Add 'skip' option to crawlers 2021-06-04 18:33:02 +02:00
Always use '/' as path separator for regex rules Previously, regex-matching paths on windows would, in some cases, require four backslashes ('\\\\') to escape a single path separator. That's just too much. With this commit, regex transforms now use '/' instead of '\' as path separator, meaning rules can more easily be shared between platforms (although they are not guaranteed to be 100% compatible since on Windows, '\' is still recognized as a path separator). To make rules more intuitive to write, local relative paths are now also printed with '/' as path separator on Windows. Since Windows also accepts '/' as path separator, this change doesn't really affect other rules that parse their sides as paths. 2021-06-04 18:02:45 +02:00			`### Changed`

Add credential file authenticator 2021-05-31 17:55:56 +02:00			`### Added`
			- `credential-file` authenticator

Add credential file authenticator 2021-05-31 17:55:56 +02:00
Store cookies in text-based format Using the stdlib's http.cookie module, cookies are now stored as one "Set-Cookie" header per line. Previously, the aiohttp.CookieJar's save() and load() methods were used (which use pickling). 2021-05-31 22:04:56 +02:00			`### Changed`
			`- Cookies are now stored in a text-based format`

Fix exercise date parsing for non-group submissions ILIAS apparently changes the order of the fields as it sees fit, so we now try to parse every column, starting at from the right, as a date. The first column that parses successfully is then used. 2021-05-31 18:00:42 +02:00			`### Fixed`
			`- Date parsing now also works correctly in non-group exercises`
