@subheading What are @qq{Tiny examples}?

A tiny example is an example from which @strong{nothing} can be removed.
@divEnd

@divClass{column-left-bottom}
@subheading Why create them?

@divClass{keep-bullets}
@itemize

@item
The simpler the example is, the quicker potential helpers can
understand it and help you.

@item
A tiny example demonstrates that you have put effort towards
solving the problem yourself.  When people send huge portions of
input, it looks like they don't care if we help them or not.

@item
Creating a tiny example helps you to understand what is
happening.  Many false problem reports can be avoided by
attempting to create a tiny example; if you cannot replicate a
@qq{bug} in a tiny example, then the problem was probably an
insufficient understanding of LilyPond, not an actual bug!

@end itemize
@divEnd

@divEnd


@divClass{column-right-bottom}
@subheading How to create them?

@divClass{keep-bullets}
@itemize

@item
Include the @code{\version} number.

@item
Make it small!  Examples about spacing or page layout might
require many bars of music, but most issues can be reproduced
using less than a single measure.

@item
When trying to create an example, try commenting out @w{(@code{%}
or @code{%@{ @dots{} %@}})} sections of your file.  If you
can comment something while still demonstrating the main idea,
then remove the commented-material.

@item
Avoid using complicated notes, keys or time signatures, unless
the bug is about the behavior of those items.

@item
Do not use @code{\override} or @code{\set} commands unless the bug
is about those specific commands.

@item
Optionally, attach an image showing the desired graphical output.

@end itemize
@divEnd

@divEnd

@divClass{column-center-bottom}
@subheading How tiny should they be?

Is the code below a minimal example?

@example
\version "2.14.1"
\include "english.ly"

\score @{
  \new Staff @{
    \key d \major
    \numericTimeSignature
    \time 2/4
    <cs' d'' b''>16 <cs' d'' b''>8.
    %% Here: the tie on the D's looks funny
    %% Too tall? Left-hand endpoint is not aligned with the B tie?
    ~
    <cs' d'' b''>8 [ <b d'' a''> ]
  @}
@}
@end example

Well, it is not very big, but a truly minimal example is here:

@example
\version "2.14.1"
@{
  % middle tie looks funny here:
  <c' d'' b''>8. ~ <c' d'' b''>8
@}
@end example

Very few tiny examples exceed 10 lines of code -
quite often 4 lines are enough to demonstrate the problem!

@divClass{keep-bullets}
@itemize

@item
If you are subscribed to the @uref{mailto:bug-lilypond@@gnu.org,

If you are not subscribed, you can still post a bug report with
the

gmane lilypond.bugs web interface}.

However, there is a strict @qq{no top-posting} check on the gmane
interface, which is often incorrectly triggered by lilypond files.
To avoid this, please add:

@example
> I'm not top posting.

@subheading Step 4: Wait for a response

Once your bug report has been sent to the list, our Bug Squad will
examine it; they may ask you for more information.  You will be notified
when the report will be added to the bug tracker. Please allow up to 4 days,
as we have a limited number of volunteers for this task.

Once a bug has been added to the tracker, you can comment it to add
more information about it.
You may also mark the bug so that you automatically receive emails when
any activity on the bug occurs.  This requires you have a google
account.

@divClass{column-center-bottom}
@subheading Optional help: show the desired behavior

Once an issue has been added to the tracker, it can be very

@node GSoC 2012

@divClass{column-center-top}
@subheading What is Google Summer of Code?

It is a global program run by Google that offers students stipends
for working on open source software projects during summer vacations.

The LilyPond Team decided that this is an excellent opportunity to find
new contributors and encourage students already participating in LilyPond
development to become more involved.  One of our contributors was accepted
for 2012 edition of the program as part of the
@uref{http://www.gnu.org/, GNU project};
we hope to participate in future editions as well.

@divEnd

@divClass{column-center-bottom}
@subheading Our 2012 Ideas List

Below is a list of projects that we suggested for GSoC 2012 students.
Although the application period is over, we decided to keep this webpage
online as an inspiration for anyone who is interested in developing LilyPond.
Some members of the development team are willing to help people who would like
to tackle these projects.

Of course, there are many more things to improve in LilyPond, including
very small ones.  A full list of all known issues can be found
@uref{http://code.google.com/p/lilypond/issues/list, here}.

@subheading Grace notes

Fix problems with synchronization of grace notes,
together with all underlying architecture (see
@uref{http://code.google.com/p/lilypond/issues/detail?id=34,
issue 34 in our tracker}).  Grace notes are confusing to LilyPond's
timing because they're like going back in time.  This causes weird
effects, especially when one staff has a grace note and the other
doesn't.

@strong{Difficulty:} medium

@strong{Requirements:} C++, MIDI

@strong{Recommended:} familiarity with LilyPond internals

@strong{Mentor(s):} Mike Solomon, Carl Sorensen

@subheading MusicXML

Adding comprehensive MusicXML export and improving import,
together with tests checking that it works. Depending on time available,
implement some or all of the following:

@divClass{keep-bullets}
@itemize

@item
Handle basic musical content export like the MIDI export (i.e. using
dedicated exporter classes, derived from the translator class)

@item
Build the XML tree of the basic musical content,
add a connection from music event to XML tag

@item
Let all LilyPond engravers do their job

@item
Add ability to link each output object
(basically each stencil / group of stencils) to the music cause
(and thus to the XML tag in the XML tree)

@item
Add a XML output backend, which can then add the layout information
for each output object to the XML tags

@end itemize
@divEnd

The goal will be considered achieved when a (previously chosen) score
could be imported from MusicXML and exported back with no unintentional
loss of data.

@strong{Difficulty:} medium

@strong{Requirements:} MusicXML, Python, basic LilyPond knowledge

@strong{Mentor(s):} Reinhold Kainhofer, Mike Solomon

Familiarity with other scorewriters (for cross-testing) would be a nice
bonus.

@subheading Improve slurs and ties

The default shape of slur and tie curves is often unsatisfactory.
Ties on enharmonic notes @code{@{ cis'~ des' @}} are not supported,
ties "broken" by clef or staff change aren't supported well.
The project includes collecting and sorting examples of bad output,
deciding on the intended output and writing the actual code.

@strong{Difficulty:} hard

@strong{Requirements:} C++, experience with writing heuristics

@strong{Recommended knowledge:} LilyPond knowledge, aesthetic sense

@strong{Mentor(s):} Mike Solomon

@subheading Adding special variant of font glyphs
Adding on-staff-line, between-staff-line, shorter and narrower variants
of some glyphs, for example accidentals, together with a generic
infrastructure to support them.  An example is ancient notation breve
notehead coming in two variants, with smaller and bigger hole.

@strong{Difficulty:} easy

@strong{Requirements:} MetaFont, C++, good eye for details

@strong{Recommended knowledge:} basic LilyPond knowledge

@strong{Mentor(s):} Werner Lemberg

@subheading Improve beaming

Default positioning of regular, cross-staff, broken and kneed beams
should be improved.  Beaming should depend on context and neighbor notes
(see @uref{http://icking-music-archive.org/lists/sottisier/sottieng.pdf,
section 2.2 here}).  If possible, reduce beaming computation time.

@strong{Difficulty:} medium

@strong{Requirements:} C++, experience with writing heuristics

@strong{Recommended knowledge:} aesthetic sense

@strong{Mentor(s):} Mike Solomon, Carl Sorensen

@subheading Clean up various compilation warnings

Clean up compiler warnings, static code analysis, and valgrind warnings.
Automatic code analysis tools (warnings in @code{g++} and @code{clang})
and analysis tools like valgrind memory leak detection and callgrind
code profilers provide valuable information about possible flaws in C++
code.  Cleaning these warnings would allow us to automatically reject
any patch which introduced extra warnings.

@strong{Difficulty:} medium

@strong{Requirements:} C++
