Changelog

All notable changes to this project will be documented in this file. The format is based on Keep a Changelog.

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

  • Support for MOB videos in page descriptions
  • Clickable links in the report to directly open new/modified/not-deleted files
  • Support for non KIT shibboleth login

3.6.0 - 2024-10-23

Added

  • Generic ilias-web crawler and ilias-web CLI command
  • Support for the course overview page. Using this URL as a target might cause duplication warnings, as subgroups are listed separately.
  • Support for named capture groups in regex transforms

Added

  • no-delete-prompt-override conflict resolution strategy

  • Remove size suffix for files in content pages

Fixed

  • Crawling of courses with the timeline view as the default tab

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
  • More exceptions are handled properly

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

Added

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

Changed

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

  • 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
