Re: Markup parsing question
Thank you David, this explains me what I didn't understand.
It turned out that somehow I was looking at a bad parser.yy.
Actually I'm not running/debugging the C code, but instead only reading it
(and porting some of the parsing code to Java).

You are wrong. \markuplines (soon to become \markuplist) takes this
markup list verbatim. \markup, however, wraps it in a line-markup. Put
the following after your assignment:
#(begin)
#(display dot)
This produces:
(#procedure line-markup (layout props args) ( q (#procedure
musicglyph-markup (layout props glyph-name) accordion.dot)))
Now when I'm referring to it in c^\dot, the following code is run:
if (Text_interface::is_markup (sid)) {
return MARKUP_IDENTIFIER;
} else if (Text_interface::is_markup_list (sid)) {
return MARKUPLINES_IDENTIFIER;
}
The result of this must be MARKUP_IDENTIFIER (as only those can be
used as direction_reqd_event - gen_text_def - full_markup
But if I look in Text_interface.isMarkup, it will just do the
following:
return (scm_is_string (x)
|| (scm_is_pair (x)
SCM_BOOL_F
!= scm_object_property (scm_car (x),
ly_symbol2scm (markup-signature;
}
So my value, ( q (musicglyph accordion.dot)) will not be
considered as a markup, but instead a markup list, so I'm getting a
parse error.
Can you help me where I misunderstand the code?
Have you actually tried your code? Works fine here.

Why I ask that?

And lilypond file format is really easy to use. So my idea is: * My program creates a tune. * Create a string with the lilypond description. * Calls a function, and it creates a external midi file * My program uses the midi file. Check JFugue.

Re: Grammar: meaning of terminals
The lexer reads regular expressions, and tries to match them to a rule.
A rule will return a token and a value (yylval). These two will be used
by the parser to interpret the input.
This is so simple.
So for example how a note name is recognized:
a note name like fs will be read as [a-zA-Z\200-\377]+ regular
expression (ALPHAWORD in lexer.ll).
In notes and figure lexer state (notes, figures in lexer.ll) it will
return scan_bare_word, based on the rule:
notes,figures{
{ALPHAWORD}{
return scan_bare_word (YYText ());
}
scan_bare_word is a function that takes the matched input and return the
appropriate token and set the appropriate value in yylval. Look at the
implementation of this function to understand how that token is actually
generated.

Re: LilyPond web service
Just a heads up for those who are thinking about hosting part of the distributed LilyPond server vision. I created a Java servlet based service for LilyPond for the purposes of Google Wave. It runs on a virtual private server with 256MB RAM (running Ubuntu Linux, Tomcat, a database and nothing more), and performs quite well for the simple tasks. Some important points though: - it allows only one LilyPond processing request at one time, so a queue is created. I tested it with parallel processes but they killed the server (the memory was not enough) - one LilyPond process can get at most 15sec of CPU time, and 32MB physical and 64MB virtual memory. This must be more fine tuning, including the LILYPOND_GC_YIELD setting, as this doesn't allow long parts to be compiled. - LilyPond runs in jail mode, which is very good The installation of the service is very easy, the hard part is actually setting up the jail mode for LilyPond, GhostScript and ImageMagick. So good instructions will be created for this. Valentin Villenave wrote: 2009/10/12 Harmath Dénes harmathde...@gmail.com: However, for it to work, of course, a web service is needed which takes LilyPond code as its GET argument, renders it with LilyPond (safe or jail mode of course), and returns the result as cropped PNG image. (Multiple servers can be configured for load distribution.) Is there an official LilyPond web service somewhere online like this (similar to http://noteserver.org for Guido)? The only LilyPond server at this point is the LilyPond Snippet Repository at Milano University. But it tends to go down as soon as several people use it at the same time :-) A few other servers were installed, particularly for LilyPond web plugins such as the Wordpress, the MediaWiki or the Spip plugins. I also began installing LilyPond on a dedicated server for the LilyNet website, but it's not nearly powerful enough. LilyPond requires a *lot* of resources. If not, I strongly propose setting up a server for this purpose. I already implemented this HTTP service. It needs only PHP, LilyPond and ImageMagick installed. Could you host this service? Until Google Wave gets more widespread adoptance, users could benefit from it already with just a minimalistic form-based web interface. The LilyPond community unfortunately doesn't have the resources to host such a service, however interesting it may be. We're already sponsored for our bandwidth and web resources, but that's about all we can get. However, if you do develop a convenient web-application and set up an experimental web-server, there's little doubt that many LilyPonders will follow you and try to help you with regard to the hosting server.

Why would that be? Did you not have a Flex generated .l file? If the

Developing C++ code on Windows is practically impossible, but can be
well done with the VirtualBox pc for which I host the ISO (see the CG :))
So it doesn't matter whether the tool is supported on Windows or not.
But first:
- what are the rules?
- and then how we force that
You can even force that with manually, that is not approving code that
doesn't adhere, but all that can be automatized could be. So there might
be some static code analysis tools to be used as well.

In general, all code should be portable and maintainable, that is - make sure code is tool-agnostic, - make sure there are good tool support That's why it would be a bad idea to adopt R6RS for LilyPond (no tools), and it is a bad idea to make LilyPond code GUILE-dependent (no life outside Guile). Still, it is ok if the Guile modules used are implemented in pure R5RS - for example the module system is implemented using core R5RS features, so that can be safely used, still producing portable Scheme code.

Re: lilybuntu confusion
1) Memory: use the recommended base size of 384 MB? * are there system requirements for compiling LilyPond? * Do I need more RAM to compile the program than I would to compile just the docs? * I initially selected 384, but then VirtualBox warned me that 384 MB is more than 75% of all my RAM (I'm on an older computer with only 504 MB RAM). That would've left 120 MB for everything else and the warning said that was a bad idea. But I didn't know what to lower it to, or if I could lower it at all. So I changed the 384 to 200. I still don't know if it matters. As long as there's enough memory to run things, you're OK. Extra memory needs will be met by using virtual memory (on the hard disk). Well, I would recommend _at least_ 384MB, but running two OS'es at the same time on a computer with 0.5G RAM can be hard. 3) Storage type: Dynamically exapanding storage? Yes, definitely. 5) Virtual Location Disk Size: use recommended (8 GB)? * Does compiling LilyPond require more/less? * What if I only want to allocate 2GB (hypothetically)? * If I select 8GB, it'll start at the base size in expand dynamically anyway, right? It would be good to understand this. Probably want to use the recommended. 2GB may make it too tight. You can't even install the OS on 2GB. You need at least a 4GB hard disk, but that could be tight as well. I would recommend 6GB.

Re: guile sandbox without guile
I played a bit with jEdit's console:
In jEdit Console plugin you need to add
%set GUILE_LOAD_PATH g:\program files\lilypond\usr\share\guile\1.8
and then you can start guile from the System Shell.
Unfortunately the LilyPond shell doesn't support the #(top-repl)
discussed in
http://lilypond.org/doc/v2.13/Documentation/devel/contrib-guide/Debugging-LilyPond#Debugging-LilyPond
So if you want the guile prompt you need to start LilyPond from the
system shell, but not from the bin directory (I don't why it happens,
that when you start lilypond.exe from its directory, it doesn't start):
G:\ g:\Program Files\LilyPond\usr\bin\lilypond ${f}

I want to develop automatic lyric contraction
Hi, I'd like to dig myself into the C++ source of LilyPond. I have a long-wished feature, for support automatic lyric contraction. That means the following: When there is not enough space for a hyphen to appear, the hyphen is removed. Like instead of yeah - yeah - yeah, yeah yeah yeah. In these cases I would like LilyPond to automatically contract it to yeahyeah - yeah, moving the syllables, taking kerning into account. Do you think it is feasible without major rewrite? I do see some callback to the lyric syllable in the hyphen engraver, but I'm not sure about it. (Also, for some languages contraction would change the spelling, e.g. in German c-k may become kk, Hungarian sz-sz becomes ssz. But that's another story.)

Re: I want to develop automatic lyric contraction
Generally I would fix the first syllable's position (leaving it as it is), and then move the following ones closer to the first. I believe this would always produce pleasant results, as if one of the last syllables would go too early, then it would be still long enough to remain under the corresponding note (because if it weren't long, then it wouldn't make the hyphen disappear in normal spacing.) However, there should be a way to change the first syllable's position, because in the hand-engraved scores I looked at, they often follow special rules: generally a syllable has 3 letters, it is centered under the note, but a 2 letter syllable is aligned to the left side of the note. So if you have a word with 2 syllables, like money, then in contraction ney will still be centered under its note, but mo will be moved to the right. But this is not general rule, so I think it would be enought to make sure there is a property, which in contraction situations would allow me to override the default spacing.

Do you think it is feasible without major rewrite? I do see some callback to the lyric syllable in the hyphen engraver, but I'm not sure about it. I think it would be a difficult to implement. You'd have to replace the hyphen code and write code that checks the distance between this syllable and the next; if that distance is too small, it would remove or make transparent the following syllable, and change the text of the 1st to be the contracted version. There are some other hairy issues: in general, any contraction can change the spelling of a word, so what happens if you have a - b - c - d - e and it is set very tightly? Any contraction change the spelling of any syllable (and the space it takes up), so how do you decide between contracting aB - c - d - e and a - b - Cd - e first? the changed spelling may alter the size of the word, and may trigger another round of contractions. I'd go one syllable by one. Also, I would not allow automatic change of spelling - that is generally impossible without a full hyphenation engine with dictionary (even in those cases it often mistakes), so the user would have to explicitly set spell-changing upon contraction. I can hardly imagine cases when the respelling results in more space, but certainly that would call for some handling - but that could be solved by the user by setting the minimum-distance in those places.

(again, I'm happy to dump whatever suggestions people throw at me in the CG) I've never worked on C++ files, but I opened one up in Geany and it had nice syntax highlighting plus a build menu with lots of options, including targets for make, compiling, building, etc. Geany's my favorite GUI editor and it's available for both Windows and Linux. A developer would be better able to judge its worth as an IDE, but I like it very much and it's easy to install from the repos. BTW I've been fiddling with my Lilybuntu virtual machine and finally figured out how to make it go fullscreen (previously I'd only been able to view it in a 800x600 window--very annoying). It's a bit of a trick to make this work on a virtual Linux machine in Sun's VirtualBox. Once you get it set up, though, it's really amazing. It's a matter of successfully installing Guest Additions. I don't know if you want to get into VirtualBox issues in the CG, especially since others might use different virtualization tools, but getting it set up properly will make a big difference in the usability of the virtual machine. Once it's fullscreen it looks as if it's the real OS on your computer. Very nice. I now have my Windows VMs set up this way (much easier on the Windows VMs to set up Guest Additions) and it's excellent for testing.

Re: development on windows
Tim, have you used VMware before? This should allow you to compile LilyPond inside a virtual machine. I'm not certain what the best way is to transfer the iso from Jonathan to you, though. The goal of this iso to make it usable on a virtualization tool. The open source Sun VirtualBox can for example mount this as the virtual hard disk. Once it's ready maybe I can create a torrent? I've never done that before but it's probably the best way to transfer it. It'll take a while. I can also give you FTP access to one of the servers run by me where you could upload it.

As we are looking for windows-experienced developers I really think that the ubuntu way would be better, it is easier for us windowsers. If you guys think it would be useful then I'll have a go at it. I think I can remaster xubuntu with all the Lilypond build tools and get it under 700MB to fit on a CD. I would go with Debian but the tool remastersys is specifically made for doing Ubuntu remixes and I'm not sure it would work with straight Debian. I'm not sure if I can build it in such a way as to include the git source files. Normally that's the sort of thing in an individual user's /home directory and would be left out of the remix. When someone installs from one of these remixes it works the same way as with regular Ubuntu, they create user accounts at the time of installation. I feel that if I can get it under 700 megs with all of the build tools and with the git program installed, then just about any user can open a terminal and copy-paste the git commands you put together in the CG to grab the source code.

Re: Spanish Translation
You only need to - create a messages_es.properties file besides the messages.properties, and - create a LilyPondTool_es.props file containing the messages from the LilyPondTool.props file. - the LilyPondTool_es.props file shouldn't contain anything but localized messages - the localization files shouldn't contain non-ascii (not even latin1-extended) characters. Instead we must use the unicode character code in \u003b format. It can be solved by a simple searchreplace or there are tools for this. After doing this, the LilyPondTool_es.props file must be placed into the properties folder of jEdit along with other localization files. Actually jEdit can be localized this way: you just override some properties coming from other places - most plugins can be translated this way as they use this method for localization. For example if you look at Console plugin source, you can translate the messages from Console.props and put your .props file into the properties folder of jEdit. Unfortunately this method sucks but there is no better way. The message_es.properties files follows the normal way: it will be automatically loaded if JEdit/LilyPondTool is run on a machine with es locale set.

Hi, In the last 3 weeks I created the base for an R5RS Scheme interpreter written in Java, aimed at GUILE compatibility.

I hope you know what that means... syntax checking, autocompletion in Scheme parts, Wysiwym display etc. However, even to correctly parse LilyPond files I must implement LilyPond's exported interfaces, that is, Scheme procedures beginning with ly:, which are implemented as C++ functions.

Hi, in property-init.ly I found this: aikenHeads = \set shapeNoteStyles = ##(do re mi fa #f la ti) That seems to be a vector definition in Scheme: #(do re mi fa #f la ti) However, it is not a valid Scheme expression, at least according to its formal grammar and the online Scheme interpreter, http://sisc-scheme.org/sisc-online.php What is your opinion?

Re: Strange (buggy) Scheme assignment
Yes, it's a vector, but is it a standalone expression?

Ok, thanks, should I create patches for these cases - there are some in the declarations? Anyway I wonder how guile could accept these.

The guile page says: Like lists, vectors have to be quoted: '#(a b c) = #(a b c) Indeed, my mistake. The examples later on the guile documentation use quoted sharp-paren expressions. Vectors are not self evaluating according to R5RS 7.1.3: self-evaluating -- boolean | number | character | string So in LilyPond literal vectors should be quoted: aikenHeads = \set shapeNoteStyles = #'#(do re mi fa #f la ti) Nicolas ___ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
Developer docs
Valentin Villenave wrote: Hi David, hi everybody. David's feature request has been officially added as http://code.google.com/p/lilypond/issues/detail?id=559 I'm both happy and sad to admit this request: I am happy to see that people like David care about making LilyPond an even better program, through such documented requests. And I'm sad because I have to warn you that, honestly, we deeply lack resources. ... simply developers. And I think developer documentation as well. 2 or 3 years ago I tried to implement something in the LilyPond codebase. Not to mention I have no idea how to debug such a source code, I just couldn't find my way through the smob, robust_anythings, Scheme-related C Macros, functions like scm_sloppy_assq, and so on. Because I've implemented a Java parser for LilyPond (and found that because of the great liberty of the format makes it actually impossible to check the grammar without actually interpreting everything), now I have a pretty clear understanding of the lexer and the parser. But with other parts of the code I found it very, very hard to read. Perhaps because I am a Java developer for almost 10 years and got used to javadocs everywhere. At least: shouldn't we use namespaces? To not mix lexer class (not even class, but yacc/flex code!) with engravers and common classes (like Moment)?

Re: Syntax highlighting in LilyPad?
Actually java need not be installed. You can zip together the whole editor distribution, and use it without any installing, but just unzipping. So really it would involve creating a folder structure: lilypondtool -- jedit (containing all necessary plugins in the jars directory) -- jre pdf reader you can also put some predefined properties into, to make everything work out of the box. the jre is also redistributable in this form according to the license. Actually it would be rather easy to create an installer (with nsis for example) that installs lilypond, jedit, java and external pdf reader, and sets the properties file of LilyPondTool to find everything out of the box. It's a pity I don't have time for it :-( Bert ___ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
Re: Syntax highlighting in LilyPad?
You are always welcome to send patches, bug reports etc. on http://www.sourceforge.net/projects/lily4jedit. The silly mix can remain from the time when lilypond itself was a silly mix thanks to cygwin :-) However, I'd suggest packaging a lightweight gpl text editor with syntax highlighting capabilities packaged with lilypond.

I'm very interested in see some advances in these developments, mainly for my win32-only students. Please keep us informed, thanks! IMO, a pity from jEdit is that preset paths and the like do not come configured for windows nor unix, but a silly mix of the two; at least in my short experience.

Re: LilyPond parser for Canorus
How does JEdit and JLilyTool solve autocompletion for example? Autocompletion is very simple - only finds a regex at the cursor position, and then finds the possible choices only based on the Documentation. So if you move an engraver to an other context, the autocompletion will not find it. This is a place for enhancement. There is also a simple parser that is a rewrite of LilyPond's lexer and parser in ANTLR. The rewrite is not trivial, as LilyPond uses lex and bison, i.e. LALR parsing, while ANTLR is LL(k) Actually I think that if you want to create a complete LilyPond parser, you would rewrite LilyPond itself. Just think of that you need to parse all the Scheme code, just to find if a command is a markup command or not. Bert What I'd like to is to share the most code as possible for easier maintainence and for being up-to-date. What do you think?

Re: charge of lilypond
I propose (at least in windows) to leave a part of the program resident so that invocation are less painful. Unless it is being swapped out to the virtual memory.

I don't think that lilypond path should be in the PATH. Bert ___ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
Re: Windows Releases
Of course it should, but probably not the current \bin\ folder Why? On Windows platforms people rarely use the PATH to run programs. Bert ___ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
Re: Windows Releases
Putting these into the path would also not help. - you can not run convert-ly.py - you must use python convert-ly.py - But if you do, you must say: python c:\program files\lilypond\usr\bin\convert-ly.py So you didn't gain much. Still I don't see it is useful. Perhaps we should look at the possibilities of packaging LilyPond with JEdit + Java + LilyPondTool. Actually Java license allows to distribute the runtime with your application, jEdit is GPL. Neither Java, nor jEdit needs anything written to the registry to work, they just can be zipped together. So we could make a directory structure like this: Program Files - LilyPond -- usr -- bin -- java --- bin javaw.exe -- jedit --- jars LilyPondTool.jar Console.jar ... And make a shortcut that runs: c:\Program Files\LilyPond\java\bin\javaw.exe -jar c:\Program Files\LilyPond\jedit\jedit.jar The download size would not be small: LilyPond 18MB jEdit 2MB jEdit plugins 15MB Java runtime 24MB That is 59MB.

Re: Windows Releases
I was thinking a bit more. Installing and uninstalling LilyPond itself should remain separate from jEdit. So there should be one installer that separately installs the two. Bert ___ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel

Re: proofreading tutorial
Ok, I'm happy to do this. But what should I write about emacs, vim etc? Should I write about configuration, or link to the manual?
