289 @unnumberedsec Tiny examples
291 @divClass{column-center-top}
292 @subheading What are @qq{Tiny examples}?
294 A tiny example is an example from which @strong{nothing} can be removed.
297 @divClass{column-left-bottom}
298 @subheading Why create them?
300 @divClass{keep-bullets}
304 The simpler the example is, the quicker potential helpers can
305 understand it and help you.
308 A tiny example demonstrates that you have put effort towards
309 solving the problem yourself. When people send huge portions of
310 input, it looks like they don't care if we help them or not.
313 Creating a tiny example helps you to understand what is
314 happening. Many false problem reports can be avoided by
315 attempting to create a tiny example; if you cannot replicate a
316 @qq{bug} in a tiny example, then the problem was probably an
317 insufficient understanding of LilyPond, not an actual bug!
325 @divClass{column-right-bottom}
326 @subheading How to create them?
328 @divClass{keep-bullets}
332 Include the @code{\version} number.
335 Make it small! Examples about spacing or page layout might
336 require many bars of music, but most issues can be reproduced
337 using less than a single measure.
340 When trying to create an example, try commenting out @w{(@code{%}
341 or @code{%@{ @dots{} %@}})} sections of your file. If you
342 can comment something while still demonstrating the main idea,
343 then remove the commented-material.
346 Avoid using complicated notes, keys or time signatures, unless
347 the bug is about the behavior of those items.
350 Do not use @code{\override} or @code{\set} commands unless the bug
351 is about those specific commands.
354 Optionally, attach an image showing the desired graphical output.
361 @divClass{column-center-bottom}
362 @subheading How tiny should they be?
364 Is the code below a minimal example?
368 \include "english.ly"
373 \numericTimeSignature
375 <cs' d'' b''>16 <cs' d'' b''>8.
376 %% Here: the tie on the D's looks funny
377 %% Too tall? Left-hand endpoint is not aligned with the B tie?
379 <cs' d'' b''>8 [ <b d'' a''> ]
384 Well, it is not very big, but a truly minimal example is here:
389 % middle tie looks funny here:
390 <c' d'' b''>8. ~ <c' d'' b''>8
394 Very few tiny examples exceed 10 lines of code -
395 quite often 4 lines are enough to demonstrate the problem!
401 @unnumberedsec Bug reports
404 @divClass{heading-center}
405 If you have input that results in a crash or wrong output,
409 @divClass{column-center-top}
410 @subheading Step 1: Known bugs
412 We may already know about this bug. Check here:
415 @uref{http://sourceforge.net/p/testlilyissues/issues/}
418 @warning{Please @strong{DO NOT} add bug reports directly to the
419 bug tracker. Once an issue has been added to the tracker, feel
420 free to add more information to that report.}
425 @divClass{column-left-bottom}
426 @subheading Step 2: Creating a bug report
428 If you have discovered a bug which is not listed,
429 please help us by creating a bug report.
431 @warning{We only accept reports in the form of
432 @ref{Tiny examples}. We have very limited resources,
433 so any non-minimal example will be rejected. Almost
434 every bug can be demonstrated in four notes or less!}
436 Here is an example of a good bug report:
439 % Accidentals should be printed for only
440 % the first note in a tie, but this version
441 % prints flats on both notes.
452 @divClass{column-right-bottom}
453 @subheading Step 3: Sending a bug report
455 Once you have verified that the issue is not already known and
456 created a bug report, please send it to us!
458 @divClass{keep-bullets}
462 If you are subscribed to the @uref{mailto:bug-lilypond@@gnu.org,
463 bug-lilypond@@gnu.org} mailing list, send an email like normal.
466 If you are not subscribed, you can still post a bug report with
468 @uref{http://post.gmane.org/post.php?group=gmane.comp.gnu.lilypond.bugs,
469 gmane lilypond.bugs web interface}.
471 However, there is a strict @qq{no top-posting} check on the gmane
472 interface, which is often incorrectly triggered by lilypond files.
473 To avoid this, please add:
476 > I'm not top posting.
480 (you @emph{must} include the @code{>} ) to the top of your bug
487 @divClass{column-center-bottom}
488 @subheading Step 4: Wait for a response
490 Once your bug report has been sent to the list, our Bug Squad will
491 examine it; they may ask you for more information. You will be notified
492 when the report will be added to the bug tracker. Please allow up to 4
493 days, as we have a limited number of volunteers for this task.
495 Once a bug has been added to the tracker, you can comment it to add
496 more information about it.
497 You may also mark the bug so that you automatically receive emails when
498 any activity on the bug occurs. This requires you have a google account
502 @divClass{column-center-bottom}
503 @subheading Optional help: show the desired behavior
505 Once an issue has been added to the tracker, it can be very
506 helpful if we can see the desired output. Feel free to add input
507 code and/or images (possibly created with other tools) which
508 demonstrate what you think it should look like!

556 @divClass{column-right-top}
557 @subheading Guidelines
559 Any user wanting to offer money in exchange for work should bear
560 in mind the following points:
564 LilyPond developers may advertise their services on the lilypond
565 email lists from time to time.
568 Any agreements between private individuals should include the
569 normal precautions when conducting business: who pays, how much do
570 they pay, with what method of payment, and upon what set of
571 conditions. We suggest that any ambiguity or uncertainty in these
572 questions should be resolved before any work begins.

883 @divClass{column-center-top}
884 @subheading What is Google Summer of Code?
886 @uref{https://developers.google.com/open-source/gsoc/, GSoC} is a global
887 program that offers students stipends to write code for free software
888 and open source projects during the summer. It is an excellent
889 opportunity for students to gain experience with real-world software
890 development and make a contribution that benefits everyone. It brings
891 new contributors to LilyPond and enables students who are already
892 involved to become more involved. LilyPond participates in GSoC as part
893 of the @uref{http://www.gnu.org/, GNU project}.
895 We have had GSoC participants in 2012, 2015 and 2016 and encourage students
896 to apply for future summers.
898 If you have questions or would like to apply, send us an email on our
899 developer mailing list (see @ref{Contact}).
903 @divClass{column-center-middle-color2}
904 @subheading Project Ideas List
906 Below is a list of suggested projects for GSoC or for anyone who is
907 interested in helping to improve LilyPond. (Last updated: November 2016)
909 Mentor availability varies from project to project and from year to year.
910 Send us an email on our developer mailing list (see @ref{Contact}), and
911 we will help you find a mentor for a project that fits your interests
914 If you have ideas for a GSoC project that is not listed below you can
915 send us an email as well. There are a number of areas where LilyPond
916 could be improved, and our development team is always willing to help
917 those who would like to tackle a project like those listed below.
919 A full list of all the current open issues can be found
920 @uref{http://sourceforge.net/p/testlilyissues/issues/, here}.
924 @divClass{column-center-middle-color3}
925 @subheading Improve internal chord structure
927 The internal representation of LilyPond chords is not powerful enough
928 to capture the nomenclature of jazz chords. Currently the chord has
929 a root, a bass and an inversion. It would be nice to be able to handle
930 stacked or polychords, minor/major, etc. In order to do this, an
931 internal representation with the ability to capture the essence of
932 complex chords must be developed. As a bonus, once the internal
933 representation is developed, the output formatting of chord names can
936 @strong{Difficulty:} Easy/medium
937 @strong{Requirements:} Scheme (Guile), but the level necessary can be
939 @strong{Recommended:} Chord theory and naming
940 @strong{Mentor:} Carl Sorensen
944 @divClass{column-center-middle-color3}
945 @subheading Adding variants of font glyphs
947 @divClass{keep-bullets}
951 Adding @q{on} and @q{between} staff-line variants.
954 Shorter and narrower variants of some glyphs for example, accidentals.
955 Another, more specific example could be an ancient notation breve
956 notehead coming in two variants one with a small or big @q{hole} within
962 @strong{Difficulty:} easy
963 @strong{Requirements:} MetaFont, C++, good eye for details
964 @strong{Recommended knowledge:} basic LilyPond knowledge
965 @strong{Mentor:} Werner Lemberg
969 @divClass{column-center-middle-color3}
970 @subheading Grace notes
972 Fix problems with synchronization of grace notes. Grace notes can
973 interfere with LilyPond's timing and cause odd effects, especially when
974 multiple staffs are used where some have grace notes and others don't.
975 This is one of the longest-standing and one of the more embarrassing
976 @uref{https://sourceforge.net/p/testlilyissues/issues/34/,bugs} in
979 @strong{Difficulty:} medium
980 @strong{Requirements:} C++, MIDI
981 @strong{Recommended:} familiarity with LilyPond internals
982 @strong{Potential Mentors:} Mike Solomon (not available for GSoC 2016),
987 @divClass{column-center-middle-color3}
988 @subheading Improve default beam positioning
990 For regular, cross-staff, broken and kneed beams. Beaming should depend
991 on context and neighbor notes (see section 2.2 of

1004 @subheading Help improve compilation behavior
1006 Automatic code analysis tools, like valgrind memory leak detection or
1007 callgrind code profilers, provide valuable information about possible
1008 flaws in our C++ code. Cleaning up warnings would allow us to automate
1009 the rejection of any patch which introduced extra warnings.

1019 @subheading MusicXML
1021 Improving MusicXML import and export functions:
1023 @divClass{keep-bullets}
1027 Handle basic musical content export like the MIDI export (i.e. using
1028 dedicated exporter classes, derived from the translator class).
1031 Build the XML tree of the basic musical content, add a connection from
1032 music event to XML tag.
1035 Let all LilyPond engravers do their job.
1038 Link each output object (i.e. each stencil or group of stencils) to the
1039 music cause (and thus to the XML tag in the XML tree).
1042 Add an XML output backend, which can then add layout information for
1043 each output object to the XML tags.
1048 There are several possibilities for this project, including building upon
1049 the MusicXML export project from GSoC 2015.
1051 @strong{Difficulty:} medium
1052 @strong{Requirements:} MusicXML, Python, Scheme, basic LilyPond knowledge
1053 @strong{Potential Mentors:} Reinhold Kainhofer, Mike Solomon (both not
1054 available for GSoC 2016)
1056 Familiarity with other scorewriters (for cross-testing) would also help.

1061 @subheading Improve slurs and ties
1063 The engraving quality of slurs and ties is often unsatisfactory. Ties
1064 @q{broken} by clef or staff changes are not handled well. The project
1065 could include collecting and sorting examples of bad output, deciding on
1066 the intended output and writing code to improve them.
1068 @strong{Difficulty:} hard
