Progress report #10

posted on 2017-10-22 16:00

Dear Community,

We have many important improvements since the last iteration and even more work is pending. I want to apologise for this late progress report – it has been almost three months since the last update. I'll try to improve in this regard.

Some highlights for this iteration:

  • various utilities have been replaced with alexandria equivalents
  • distinct frames don't shadow *accelerator-gestures* of their children
  • accepting-values refinements - better handling of errors and return values
  • refactor and small fixes of the recording implementation code
  • refinements in class hierarchy for streams, medium and graphics state
  • slider from 30.4.5 spec section has been implemented
  • scrolling implementation refinements
  • tab-layout extension refactor
  • improvements related to drei text editing substrate
  • user manual refinements and improvements of its building scripts
  • improvements related to the PDF backend
  • MOP code has been ported to use closer-mop portability layer
  • numerous editorial fixes in bundled specification sources
  • improvements to format-graph-from-roots
  • better Unicode support in CLX for frame title
  • general code base cleanup to decrease number of warnings during compilation
  • transparency handling in CLX backend and alpha channel support in images
  • small Listener improvements (bug fixes and cleanups)

We want to thank everybody who has contributed to the project (by improving the code base, discussions, issue reporting, providing advice and suggestions, monetary contributions etc). We are especially grateful to the following people: Nisar Ahmad, Alastair Bridgewater, John Carroll, Cyrus Harmon, Philipp Marek, Elias Mårtenson, Piotr Mieszkowski, Jan Moringen, Nick Patrick, Alessandro Serra and last but not least Robert Strandh.


All McCLIM bounties (both active and already solved) may be found here. Default bounty expiration date is 6 months after publishing it (a bounty may be reissued after that time period).

Bounties solved this iteration:

  • [$300] Replace MOP things with closer-mop portability layer
  • [$100] Keystroke accelerators may shadow keys even if inactive

Active bounties ($1800):

  • [$100] drag-test demo: dragging square to the empty position invokes the debugger (new)
  • [$100] Text field pane height is too small, clipping the bottom off characters (new)
  • [$300] Listener: repl blocks when long process runs (new)
  • [$500] Windows Backend
  • [$400] Fix Beagle backend
  • [$150] When flowing text in a FORMATTING-TABLE, the pane size is used instead of the column size
  • [$150] clx: input: english layout
  • [$100] Add PDF file generation (PDF backend)

Our current financial status is $1089 for bounties and $264 recurring monthly contributions from the supporters (thank you!).

I have been asked a question about who decides which issues have bounties on them and how the reward amounts are decided. If anyone has been wondering about the same here goes the answer: issues and prices are based on my subjective opinion indicated by problems users encounter and what I consider being worth putting bounty on it. Note though, that I'm open to suggestions (see the next paragraph). I hope that despite some potential doubts the community is generally satisfied with the progress and decisions we make. If there is some lack of transparency, please let me know what you want to know and I'll do my best to help.

Suggestions as to which other issues should have a bounty on them are appreciated and welcome. Please note that Bountysource has a functionality "Suggest an Issue" which may be found on the bounties page. If you would like to work on an issue that is not covered by the existing bounties, feel free to suggest a new bounty.

If you have any questions, doubts or suggestions – please contact me either by email (daniel@turtleware.eu) or on IRC (my nick is jackdaniel). McCLIM developers and users hang out on #clim IRC channel on Freenode.

Sincerely yours,
Daniel Kochmański
