-@subheading What is Google Summer of Code?
+@gsocCurrent
 
-@uref{https://summerofcode.withgoogle.com/, GSoC} is a global program
-that offers students stipends to write code for free software and open
-source projects during the summer.  For three months students work to
-complete a given task as part of the project's community and under the
-guidance of experienced mentors.  The program is an excellent
-opportunity for students to gain experience with real-world software
-development and make a contribution that benefits everyone.  It brings
-new contributors to LilyPond and enables students who are already
-involved to become more involved.  LilyPond participates in GSoC as part
-of the @uref{http://www.gnu.org/, GNU project}.
-
-We have had GSoC participants in 2012, 2015 and 2016 and encourage
-students to apply for the 2017 program.
-
-If you are interested to apply for the program with LilyPond as a
-project, please read the information below and don't hesitate to write
-us on our developer mailing list (see @ref{Contact}).  The student
-application window is March 20 to April 3, 2017, but we strongly
-encourage you to get in touch with our community ahead of that.

-@subheading Project Ideas List
-
-Below is a list of GSoC project ideas (last update: January 2017), but
-if you have other ideas for a project you may complete within the three
-months of the program you're welcome to make a suggestion on our
-developer mailing list (see @ref{Contact}).  There are a number of areas
-where LilyPond could be improved, and our development team is always
-willing to help those who would like to tackle a project similar to
-those listed below.  As mentor availability varies from project to
-project and from year to year it is wise to get in touch with us as
-early as possible.
-
-A full list of all the current open issues can be found
-@uref{http://sourceforge.net/p/testlilyissues/issues/, here}.
-
-
-@subsubheading Improve internal chord structure
-
-The internal representation of LilyPond chords is not powerful enough
-to capture the nomenclature of jazz chords.  Currently the chord has
-a root, a bass and an inversion.  It would be nice to be able to handle
-stacked or polychords, minor/major, etc.  In order to do this, an
-internal representation with the ability to capture the essence of
-complex chords must be developed.  As a bonus, once the internal
-representation is developed, the output formatting of chord names can
-be improved.
-
-@emph{Difficulty:} Easy/medium
-
-@emph{Requirements:} Scheme (Guile), but the level necessary can be
-easily learned
-
-@emph{Recommended:} Chord theory and naming
-
-@emph{Mentor:} Carl Sorensen

-@subsubheading Adopt the SMuFL music font encoding standard
-
-For several years now a new standard for music fonts has been around:
-@uref{http://www.smufl.org/, SMuFL}, which is also discussed as becoming part of
-a future W3C standard for music encoding.  As a FLOSS tool LilyPond should
-adhere to such an open standard instead of using an isolated solution like it
-does today.  Adopting SMuFL will help integrating LilyPond with the world of
-music notation software and eventually give LilyPond users access to a wider
-selection of notation fonts.
-
-Making LilyPond compliant to SMuFL includes remapping of the glyphs that are
-built from METAFONT sources, adjusting the glyphs' metrics to SMuFL's
-specifications, and finally updating the way LilyPond looks up and positions the
-glyphs.  As an optional part of this project LilyPond's font loading mechanism
-could be modified to use notation fonts installed as system fonts instead of
-inside the LilyPond installation.
-
-@emph{Difficulty}: Easy/medium
-
-@emph{Requirements}: C++ and willingness to get familiar with LilyPond
-internals.
-
-@emph{Recommended}: Interest and experience in working with font files.
-A little bit of METAFONT.
-
-@emph{Mentors}: Werner Lemberg, Abraham Lee
-
-
-@subsubheading Adding variants of font glyphs
-
-@divClass{keep-bullets}
-@itemize
-
-@item
-Adding @q{on} and @q{between} staff-line variants.
-
-@item
-Shorter and narrower variants of some glyphs for example, accidentals.
-Another, more specific example could be an ancient notation breve
-notehead coming in two variants one with a small or big @q{hole} within
-it.
-
-@end itemize
-@divEnd
-
-@emph{Difficulty:} easy
-
-@emph{Requirements:} MetaFont, C++, good eye for details
-
-@emph{Recommended knowledge:} basic LilyPond knowledge
-
-@emph{Mentor:} Werner Lemberg
-
-
-@subsubheading Contemporary Notation
-
-LilyPond is very good at creating non-standard notation.  Having to
-@emph{code} every graphical element instead of simply @emph{drawing}
-it may seem cumbersome but is in fact a strong asset.  New notational
-functionality can be provided with consistent appearance, automatic
-layout and a natural syntactic interface.
-
-Within the @uref{https://github.com/openlilylib/oll-core, openLilyLib}
-library system the student will create a fundamental infrastructure
-and building blocks to make creating contemporary notation easier.
-Additionally (at least) @emph{one} concrete package is developed to
-cover specific contemporary notation, such as for example the style
-of a given composer, extended playing techniques for a specific
-instrument or a certain category of effects.
-
-@emph{Difficulty:} medium
-
-@emph{Requirements:} Scheme (interaction with LilyPond internals),
-contemporary notation techniques
-
-@emph{Recommended:} sense of building hierarchical frameworks
-
-@emph{Mentors:} @emph{NN,} Urs Liska
-
-
-@subsubheading Rewrite LibreOffice LilyPond Extension with Python
-
-The @uref{http://ooolilypond.sourceforge.net/, OOoLilyPond} extension
-made it possible to conveniently include LilyPond score snippets in
-OpenOffice.org/LibreOffice Writer, Draw and Impress documents while
-keeping source and image together.  After many years without development
-an initial effort has started to make the extension compatible again
-with current versions of LibreOffice and LilyPond.
-
-However, as the LibreOffice ecosystem has changed substantially it is
-now possible to rewrite the extension with Python and PyQt.  This will
-not only be more powerful in general but will allow the integration of
-functionality from @uref{http://frescobaldi.org, Frescobaldi}, such as
-for example syntax highlighting, entry helpers, score wizards or musical
-transformations.
-
-@emph{Difficulty:} easy/medium
-
-@emph{Requirements:} Python, PyQt, LilyPond basics, LibreOffice
-extension basics
-
-@emph{Recommended knowledge:} Familiarity with Frescobaldi code based
-or willingness to learn during bonding period
-
-@emph{Mentor(s):} Joram Berger, Urs Liska, (Thorsten Behrens/LibreOffice)
-
-
-@subsubheading Automated testing and documentation for openLilyLib
-
-@uref{https://github.com/openlilylib, openLilyLib} is an extension
-framework for LilyPond code providing a “snippets” repository and a
-suite of integrated packages such as for example page layout tools or
-scholarly annotations.  It is very powerful and promising, but to really
-get off the ground two features are missing: automated testing and
-documentation generation.
-
-Automated testing is necessary to ensure modifications to functionality
-don't break other functions within the library.  There is already some
-Automated Testing of the “snippets” repository with Github's Travis
-server, but this has to be reconsidered and extended to cover the
-standalone packages too.
-
-In order to be usable for a wider range of LilyPond users on a “consumer
-level” openLilyLib needs proper documentation.  This documentation has
-to be generated from the sources, so a system is needed that requires
-package authors to document the input files and provide additional usage
-examples, from which documentation is generated.  Ideally but not
-necessarily this is implemented as a Git hook, i.e. automatically upon
-each update to the repository.  We don't prescribe the tools and
-approaches to be used, but the most widely used language in the LilyPond
-domain is Python, so there would be some bias towards that.
-Alternatively a Scheme solution could be fine so generating the
-documentation would actually be triggered by “compiling” a certain
-LilyPond input file.  In general it is advisable to make use of proven
-concepts and tools from other languages.
-
-The eventual output of the documentation should be a static HTML site
-that can be viewed locally and/or uploaded to a website.  But it would
-be beneficial if the tool would first generate an intermediate
-representation (e.g. a JSON file with additional media files) from which
-a Single Page Application could retrieve content for display on
-openLilyLib's @uref{https://openlilylib.org, website}.  Development of
-such a SPA @emph{can} be part of the GSoC project, but is optional.
-
-@emph{Difficulty:} medium
-
-@emph{Requirements:} Python or Scheme, static website generator(s) or
-(Node.js based) dynamic web application technology. Continuous
-Integration (can be learned during the bonding period)
-
-@emph{Mentors:} Urs Liska, Matteo Ceccarello

-
-@subsubheading MusicXML
-
-Improving MusicXML import and export functions:
-
-File interchange between LilyPond and other applications using MusicXML
-is still a difficult matter.  To import MusicXML it has to be converted
-manually by the @code{musicxml2ly} script.  Export @emph{to} MusicXML is
-only available as a rudimentary feature inside Frescobaldi.  In order to
-provide natural interchange between LilyPond and MusicXML based
-applications there's the need of actual import functionality and a
-dedicated export backend.
-
-Importing XML shall provide file, line and column to add origin
-attributes to generated objects.  That way point and click can be
-made available in Frescobaldi or other supported IDEs.
-
-Exporting XML shall be realized with an exporter class like the MIDI
-export.  This may be based on the work already done in
-@uref{https://github.com/DavidGarfinkle/Lilypond_MusicXMLexport, GSoC 2015}
-by David Garfinkle.  It should be checked if it is possible to use
-another XML library than the one provided by guile-2 in order to have
-this feature available in current LilyPond (which is based on guile-1.8).
-
-@emph{Difficulty:} medium
-
-@emph{Requirements:} MusicXML, Python, Scheme, basic LilyPond knowledge
-
-@emph{Recommended:} Familiarity with other scorewriters (for cross-testing)

-@subheading Information for Applicants/Participants
-
-In order to have a satisfying experience with GSoC applicants are
-strongly advised to thoroughly read the following recommendations.  Some
-of these are relevant for the application process, others for the time
-within the project.
-
-@itemize
-
-@item
-Read all applicable information on the program's website, particularly
-the
-@uref{https://developers.google.com/open-source/gsoc/resources/manual,
-students' manual}.  Make sure you fulfil all of Google's prerequisites
-and are willing to join the program as a full-time commitment over the
-coding period of three months.
-
-@item
-Please get in touch with us as soon as possible if you are interested in
-applying with a project.  Mentor availability may change without notice,
-project proposals may need fine-tuning, and many other reasons might
-require us to reject or ignore an application that hasn't been discussed
-before.
-
-@item
-We do not know in advance how many “slots” we will have available for
-projects, so please be aware that you may find yourself in competition
-with other applicants or not.  Interested or even enthusiastic response
-from our mentors is no guarantee of eventually being accepted, and
-@emph{not} being accepted does not necessarily indicate a negative
-evaluation of your application.  If we have to decide between different
-applicants there may be various aspects to consider.
-
-@item
-Integration in the LilyPond community is a fundamental part of GSoC, and
-we expect our students to make substantial efforts to become community
-members.  Within the @emph{bonding period} we expect you to write a blog
-post about your project (either on @uref{http://lilypondblog.org, Scores
-of Beauty} or on any other blog) and to be active on our mailing lists,
-introducing yourself but also communicating about unrelated tasks.  This
-goes beyond the mere setting up of a working environment and
-familiarizing yourself with the relevant code, but we think it is
-crucial for the GSoC project to be mutually satisfying.
-
-@item
-If you are accepted to the program you will have one mentor explicitly
-assigned to your project.  With this mentor you will have to agree upon
-a communication strategy, be it emails, chatrooms, issue trackers or
-voice/video chats.  Regular communication is absolutely crucial for the
-success of a GSoC project so you are stricly required to keep talking to
-your mentor.  But keep in mind that your mentor has explicitly taken
-over the responsibility for your project, and while unlike you he isn't
-paid for this activity you are still entitled to get regular attention
-from him.
-
-@item
-In order to get support from your mentor you have to give him a chance
-to follow your progress and efforts.  Therefore it is important to
-regularly commit your changes to the versioning repository you are
-working on.  Don't hesitate making unfinished code available because you
-are afraid of criticism, and don't suppress questions because you think
-they might be considered stupid.  But ideally your code should at any
-time be accompanied by compatible testing code.  Your mentor may not be
-able to properly assess your code by only @emph{reading} it without the
-opportunity to apply it in a real example.
-
-@end itemize
-
-There is a list of inactive projects in the @ref{Attic}.  We list
-projects there that are still considered valuable but for which there
-are currently no mentors available.

-
-The following list describes GSoC projects that had been proposed
-in recent years and which are still considered valuable but for
-which we currently don't have mentors available.
-
-
-@subsubheading Improve slurs and ties
-
-The engraving quality of slurs and ties is often unsatisfactory. Ties
-@q{broken} by clef or staff changes are not handled well.  The project
-could include collecting and sorting examples of bad output, deciding on
-the intended output and writing code to improve them.
-
-@emph{Difficulty:} hard
-
-@emph{Requirements:} C++, experience with writing heuristics
-
-@emph{Recommended knowledge:} LilyPond knowledge, aesthetic sense
-
-
-@subsubheading Grace notes
-
-Fix problems with synchronization of grace notes.  Grace notes can
-interfere with LilyPond's timing and cause odd effects, especially when
-multiple staffs are used where some have grace notes and others don't.
-This is one of the longest-standing and one of the more embarrassing
-@uref{https://sourceforge.net/p/testlilyissues/issues/34/,bugs} in
-LilyPond.
-
-@emph{Difficulty:} medium
-
-@emph{Requirements:} C++, MIDI
-
-@emph{Recommended:} familiarity with LilyPond internals
-
-
-@subsubheading Improve default beam positioning
-
-For regular, cross-staff, broken and kneed beams.  Beaming should depend
-on context and neighbor notes (see section 2.2 of
-@uref{http://imslp.org/wiki/Repository_of_Music-Notation_Mistakes_%28Coulon%2C_Jean-Pierre%29,
-this book}).  If possible also reduce beaming-computation time.

-
-@emph{Requirements:} C++, experience with writing heuristics
-
-@emph{Recommended knowledge:} aesthetic sense
-
-
-@subsubheading Help improve compilation behavior
-
-Automatic code analysis tools, like valgrind memory leak detection or
-callgrind code profilers, provide valuable information about possible
-flaws in our C++ code.  Cleaning up warnings would allow us to automate
-the rejection of any patch which introduced extra warnings.
