=head1 NAME LilyPond - a music typesetter =head1 SYNOPSIS lilypond [options] [inputfiles] =head1 DESCRIPTION Technically LilyPond is a preprocessor which generates TeX (or LaTeX) output which contains information to typeset a musical score. Practically it is a typesetter, which only uses TeX as an output medium. (this is handy because there exist music fonts for TeX) As a bonus, you can also output a MIDI file of what you typed. It translates script files (mudela files or F<*.ly>'s) into TeX input. Typesetting music is a complex task, whereas the message that printed music conveys is usually a simple one. LilyPond is a try at providing a simple interface for setting music. =head1 OPTIONS =over 5 =item B<-I,--include>=F, add F to the search path for input files. =item B<-M,--midi> do midi output only =item B<-d,--debug>, Turn debugging info. LilyPond will read the file F<.dstreamrc>, which tells for what functions and classes may produce copious debugging output. =item B<-w,--warranty>, Show the warranty with which LilyPond comes. (It comes with B!) =item B<-o,--output=>F, Set the default output file to F. =item B<-h,--help>, Show a summary of usage =item B<-i,--init=>F set init file to F (default: F) =item B<--include, -I>=F add F to the search path for input files. =back =head1 FEATURES =over 5 =item * ASCII script input, with identifiers (for music reuse), customizable notenames, customizable fontset =item * MIDI output lets you check if you have entered the correct notes. =item * MIDI to Mudela conversion through the mi2mu program. =item * Multiple staffs in one score. Each staff can have a different meters. =item * multiple stafftypes (melodic, rhythmic) [broken from pl28 on] =item * beams, slurs, chords, super/subscripts (accents and text), triplets, general n-plet (triplet, quadruplets, etc.), lyrics, transposition =item * multiple voices within one staff; beams optionally shared between voices. (well, more than 2 voices won't look pretty --yet.) =item * multiple scores within one input file. Each score is output to a different file. =item * clef changes, meter changes, cadenza-mode, key changes, repeat bars =back =head1 DESIGN CONSIDERATIONS LilyPond was written with some considerations in mind: =over 5 =item * Describing a well-defined language for defining music. We call this language (rather arrogantly) The Musical Definition Language (mudela for short). LilyPond reads a mudela sourcefile and outputs a TeX file. =item * We want to provide an easy-to-use interface for typesetting music in its broadest sense. This interface should be intuitive from a musical point of view. By broadest sense we mean: it is designed for music printed left to right in staffs, using notes to designate rythm and pitch. =item * LilyPond uses MusiXTeX fonts and TeX for its output. This is not a key issue: in a future version, LilyPond might bypass TeX, but at the moment TeX is very convenient for producing output. =item * Generate high-quality output. Ideally it should be of a professional quality. We'd like to render Herbert Chlapiks words, "Fine music setting is not possible without a knowledgeable printer," untrue. =item * LilyPond does not display notes directly, nor will it be rehacked to be used interactively. LilyPond writes output to a file. It will not be extended to play music, or to recognize music. =item * LilyPond is intended to run on Unix platforms, but it should be portable to any platform which can run TeX and the GNU tools =item * LilyPond is free. Commercial windows packages for setting music are abundant. Free musicprinting software is scarce. =item * LilyPond is written in GNU C++. It will not be downgraded/ported to fit broken systems. =back =head1 DISCLAIMER & COPYING POLICY LilyPond is copyright 1996,97 by its authors.

Transcript written on test.log. hw:~/musix/spacer$ xdvi test& [1] 855 Check out the input files, some of them have comments =head1 PROBLEMS If LilyPond bombs out, then please recompile using with debugging info turned on, and send a copy of the input which causes the error and a gdb stacktrace of the crash. It also helps if you can print the values of the objects. So if your trace is (gdb) backtrace 12 #0 Interval::operator+= (this=0x11fffec60..) at ../flower/interval.hh:50 #1 0x12005195c in Item::width (this=0x14008a680) at src/item.cc:39 #2 0x12008fdbc in itemlist_width (its=0x11fffed58 .. : : Than it would help if you send a dump of the Interval and the Item (use: C or use LilyPond C methods). This is a beta version of LilyPond. Please send your helpful comments and patches to me (see AUTHORS section) LilyPond is updated very frequently, the latest version is always available at: ftp://pcnov095.win.tue.nl/pub/lilypond. =head1 FILES =over 5 =item F The initialisation file with symbol tables etc. It includes files from the directory F. =back =head1 SEE ALSO There are some documentation files in the subdirectory F, among others: lilygut, lilyinput, error, faq, =head1 REMARKS LilyPond has no connection with the music package RoseGarden, other than the names being similar :-) =head1 HISTORY (for a detailed changelog, see F) LilyPond's roots lie in MPP, a preprocessor to the rather arcane MusiXTeX macro package for TeX. A friend of mine, Jan Nieuwenhuizen wrote the first 44 versions (0.01 to 0.44), then his program caught my attention, and I was slowly sucked in to the interesting problem of easily producing beautifully printed music. I contributed some code. We soon realised that MPP's design was too fundamentally broken to be repaired. It was decided to rewrite MPP. We debated a lot about the requirements to an inputformat (fall 1995). I sat down and started with a parser-first, bottom-up rewrite called mpp95 (which totally failed, obviously). After long and hard thinking, I came up with an algorithm for the horizontal spacing of multiple staffs (april 1996) I coded it (and did not test it). After starting with this fundamental piece, I slowly added the stages which come before spacing, and after. A half year later later, I had a first working version, (october 1996). I announced Patchlevel 0.0.7 (or 8) to the mutex list after asking some technical details on spacing; it was downloaded approximately 4 times. Then I got the hang of it, and in the subsequent two months, I coded until it had doubled in size (pl 23).
