@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,

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

@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.

@subheading What is Google Summer of Code?

Quoting
@uref{http://www.google-melange.com/gsoc/homepage/google/gsoc2012, GSoC website},
@qq{Google Summer of Code is a global program that offers students
stipends to write code for open source projects.  Google has worked
with the open source community to identify and fund exciting projects
for the upcoming summer.}

The LilyPond Team decided that this is an excellent opportunity to find
new contributors, encourage students already participating in LilyPond
development to become more involved, and - last but not least - write some
great code for the benefit of all!

We are participating in GSoC as a part of GNU Project.  See
@uref{http://www.gnu.org/software/soc-projects/guidelines.html, GNU GSoC webpage}
for information on how to participate.

@divEnd

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

Below is a list of projects suggested for GSoC students.  If you don't
see a project that suits you, feel free to suggest your own!
It's also possible to scale down a project if you feel it's too big.

We require that every student has basic @code{git} knowledge, and
recommend that everyone applying for projects other than the last one
have basic music notation knowledge.

@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
infrasctucture 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 Better tablature support

@divClass{keep-bullets}
@itemize

@item
non-monotonic string tunings, like Ukulele

@item
create tablature input mode (currently musical information is entered
in western-common-music-notation-terms, i.e. @qq{a quarter f sharp note}
and then converted to tablature) for transcribing medieval lute tablature

@item
implement modern tablature features, such as bends, pull-off, hammer-on

@item
if a fretboard shape is defined for a given chord, use this information when
displaying the chord on the staff (and not just display a default chord shape)

@end itemize

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++
