`org-babel-get-header' was removed in Org 9.0 and current ob-lilypond.el
doesn't call this function. My guess is you are mixing a new Org release
with an old "ob-lilypond.el".

[O] ob-lilypond and 'Symbol’s function definition is void: org-babel-get-header'

[Henrik Frisk]

Hi,

I have been trying out ob-lilypond and it works really well, except for the
arrange mode. Any attempt to run ly-tangle results in 'Symbol’s function
definition is void: org-babel-get-header' and so does an attempt to export
a file, such as the example file, in basic mode to html for instance.

I was thinking it was related to sh/shell since this appears to be a common
issue with regard to this error, but the ob-lilypond does not appear to use
any reference to sh (the doc for ob-lilypond does). I also tried to load
ob-core as was suggested in some post but that didn't work either.

Other tangle other languages works fine.

Any suggestions?

You are applying the name and caption to the source block, which is
removed (:exports results), not to the results of the source block. So,
you need to generate the results first, or at least put a RESULTS
keyword below, and apply the name and caption to it.


A-ha. Thank you. So, "What is needed to get ob-lilypond to support LaTeX 
floats and captions" is to RTFM ;)


I have often exported source code to LaTeX listings, but only infrequently 
exported results. So I wasn't clear on the mechanism. Now that you explain 
it, it makes perfect sense: the properties belong to an entity that I asked 
it not to export.


Thanks again - I can take it from here.

(PS This project is a write-up of an improvisational composition -- a lot 
of text description of the procedure, with some examples in musical 
notation along the way. It blows my mind that I can write the lilypond 
scores directly into the org document, and it all renders with C-c C-e l p. 
org-mode FTW! Again!)

[O] ob-lilypond and LaTeX floats/captions

[James Harkins]

Especially looking for users of ob-lilypond:

I currently have a few LilyPond source code blocks that are working quite well 
as inline graphics (exported to LaTeX), e.g.:

#+BEGIN_SRC lilypond :exports results :noweb yes :file ex1.eps
...
#+END_SRC

When I export, it (correctly) asks if I want to evaluate the source block, and 
the export (correctly) includes the line:

\includegraphics[width=.9\linewidth]{ex1.eps}

So far, so good.

Now, I would like to make the results a floating figure, with a caption and a 
#+name reference. So I added the following to the above block:

#+name: ex1
#+caption: One possible form of "seed" material to start the performance.
#+BEGIN_SRC lilypond :exports results :noweb yes :file ex1.eps
...
#+END_SRC

... but the #+name is not converted into a label, and the #+caption is also 
ignored.

My question, then, is: What is needed to get ob-lilypond to support LaTeX 
floats and captions? (I have a sneaky feeling it isn't trivial, but it's worth 
asking in any case.)

[O] ob-lilypond test failures

[Rasmus]

Hi,

I get lilypond errors when running make test now and I didn't see any old
messages about this.

The errors persists even after installing lilypond.

For ob-lilypond/ly-attempt-to-open-pdf:

pdf-info-query: epdfinfo: Error opening 
/home/rasmus/src/code/org-mode/testing/examples/ob-lilypond-test.pdf:No such 
file or directory

For ob-lilypond/ly-attempt-to-play-midi:

Test failed: ((should (equal "No midi file generated so can't play!" 
(org-babel-lilypond-attempt-to-play-midi midi-file))) :form (equal "No midi 
file generated so can't play!" "No midi file generated so can’t play!") :value 
nil :explanation (array-elt 29 (different-atoms (39 "#x27" "?'") (8217 "#x2019" 
"?’"

I don't know anything about lilypond.  I can make the tests not run when
lilypond is not present, but as said, they don't even seem to work when
lilypond is present.  I installed version 2.18.2.

Thanks,
Rasmus

Re: [O] ob-lilypond

[Patrick L. Schmidt]

Nick,

thank you very much for your helpful suggestions! After loading ob-lilypond.el, 
test-ob-lilypond.el and org-test.el from the git repo 38/42 tests passed. After 
I also loaded ob-org.el (git-repo) only one test failed. So I guess my org-mode 
version 8.2.7b (installed via elpa) is too old???  I tried to install the 
latest version from the git repo following the instructions at 
http://orgmode.org/manual/Installation.html.  But M-x org-version still returns 
org-mode version 8.2.7b. Do I have to get rid of the elpa-versions of org-mode. 
If yes, what’s the best way to do so?

Thanks a million!
patrick

Probably missing a load-file: in addition to ob-lilypond.el
and test-ob-lilypond.el, you need to load org-test.el (which
is in the testing subdir of the git repo).

With those three loaded (in addition to org-mode itself of course), all
42 tests pass in my setup:

Org-mode version 8.3beta (release_8.3beta-882-gf8731e @
/home/nick/elisp/org-mode/lisp/)

[Patrick L. Schmidt]

Hey all,

looks like I’m having quite a few problems with ob-lilypond (Org-mode version 
8.2.7b). To ensure that my setup is correct I ran the tests mentioned on 
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-lilypond.html#sec-9:

M-x load-file RET 
~/path/to/current/org-mode-git-repository/testing/lisp/test-ob-lilypond.el
M-x ert RET RET

And this is what I got (short version):

Selector: t

Finished at:  2015-03-25 13:32:19+0100

...FFF…F

Am I missing something? How can I get this to work?

Thanks for any help!

FWIW, I think prefix conformance should go to maint.

Also, you shouldn't use `pcase' as Org preserves compatibility with

Triggered by the discussion about it, I've looked at ob-lilypond and
found that it should be cleaned up a bit.  The defvars holding the
various commands should really be defcustoms, but I've ran out of time
for now.  If anybody thinks this should go to maint please say so,

[O] ob-lilypond: referencing named src_block not working

[Thorsten Jolitz]

Hi List, 

I try to include a (lilypond) src_block using header-arg :var, but it
does not work:

,
| #+name: common
| #+begin_src lilypond :exports none :file common.eps
|   \version "2.18.2"
|   \paper{
| oddFooterMarkup = \markup {}
|   }
| #+end_src
| 
| #+name: score
| #+begin_src lilypond :var com=common :exports results :file Mixolydian.png 
|   com
| 
|   \relative c' { 
| g a b c d e f g f e d c b a g a b c d e f g f e d c b a g1 
|  }
| #+end_src
`

When exporting this to pdf (C-c C-e l p), the Lilypond Footer is still
printed. 

OTOH when I simply copy&paste the body of src_block common into
scr_block score like this:

,
| #+begin_src lilypond :exports results :file Mixolydian.png 
|   \version "2.18.2"
|   \paper{
| oddFooterMarkup = \markup {}
|   }
|   \relative c' { 
| g a b c d e f g f e d c b a g a b c d e f g f e d c b a g1 
|  }
| #+end_src
`

the output is as expected, i.e. the Lilypond Footer is not printed. 

Am I doing something wrong here?

Thorsten

Apologies for my delayed response - I've been rather busy.

I've pushed a patch to the list to make auditioning of pdf and midi
asynchronous processes. You can either wait to see if the patch makes it
to git, or apply the patch yourself (git am).

Hopefully this will alleviate your problems with ERC!

Thanks for the heads-up.

I'm hoping to introduce remote compiling of Lilypond to help alleviate
the wait time felt when compiling Lilypond (slow but pretty)!

I'm using a similar technique for parallel testing of embedded C,
document generation, and building (using ZeroMQ). 

Best, Martyn

OK - It appears I was getting the differing results since I wasn't
passing in default parameters to my ruby blocks being called by
noweb...

was...

#+srcname:  gen_arpeggio(key,root)

now...

#+srcname:  gen_arpeggio(key="c",root="c")

Yes, this patch applied without error, and the test suite passes all
tests.  Thanks for contributing and for greatly increasing the size of
the Org-mode test suite.

I can't reproduce this problem, for example the following works for me
on the latest version of Org-mode.  I think perhaps you may not be on
the latest git HEAD.

Hopefully this patch will work for you...



port-test-ob-lilypond.patch
Description: Binary data


It looks like noweb parsing has very recently become very brittle,

Great!



One distinction that has occurred to me (especially following comments on
the mailing list) is that of "babel language" and "babel language work-flow".
In other words, I can visualise refactoring ob-lilypond to be no more than
a specification of the Lilypond syntax, and working in parallel, on a
work-flow implementation for Lilypond that is "opinionated" in terms of
adjusting org-babel settings away from their defaults / removing work-flow
noise etc. ( org-lilypond.el ) ? Would this make sense, and if so where would
it live (aligned to org-babel / a native Emacs mode perhaps)?
I hope that makes sense.



That sounds like a good idea.  Ideally ob-lilypond should include just
those elements expected by the code block interface, namely functions
for session/external evaluation, for expanding variables in code block
bodies, and for returning results to Org-mode.  I think that it would be
a good idea to develop an external org-lilypond to support a more
comprehensive workflow.


I like this.

I certainly see that the already complex task of making arrangements 
like those in Martyn's examples should be made as easy as possible.


As for the comparatively simple use cases I brought up, once they're 
supported by ob-lilypond I'd be perfectly happy to throw header 
arguments at them.

Christian

That's good to hear.  Are you up for trying to merge them into the rest
of the Org-mode test suite?  This should be as simple as placing any
org-mode example files you have in

org-mode/testing/examples/

placing the .el file defining your tests into

org-mode/testing/lisp/

and renaming all of your tests so that they start with the prefix
"ob-lilypond/"

I fully understand if you don't have the time to do this, and I should
be able to take a shot at it some time in the not-too-distant future.

My unit-tests don't currently require the Lilypond to be initialised "as a babel
language" nor a Lilypond executable AFAICT, so currently they possibly don't
need to be run "independently". I'll investigate this further.

In other words, I can visualise refactoring ob-lilypond to be no more than

If Shelagh hasn't actually authored any of ob-lilypond.el (or at least
hasn't authored more than 10 lines of) then we could simply remove her
name from the authors list and include it into the Org-mode core.  This
however may not be the best long-term solution if you anticipate her

Alright, I think we can wait for this integration, but please don't
delete your github repo in the mean time as I would like to fold this
test suite in at some point.

Ultimately this points to the more general issue of how to include Babel
language-specific tests into the Org-mode test suite s.t. they can be
executed independently of the core of the test suite.

Initially this project was intended to be a joint project between Shelagh and 
myself, but short of the initial commit, Shelagh hasn't been involved 
(unfortunately, since she will certainly know LilyPond better than I do - I 
believe she is very busy). The initial commit was broken and wasn't used. 
I'll try to contact her, but haven't an email address, so must use Github.

My test suite can live anywhere - it requires altering relative paths. 
Currently 
my test suite requires the test-build directory and contained files.

I tentatively disagree. 

Arrangement mode needs to work for me with the minimal of fuss.

Annotation mode similarly for you.

That aside you can configure locally all you wish.

Thus is the beauty of org-babel's configuration.

Great,

I have a commit ready to push to add lilypond support to Org-mode, first
I just have two questions.

1. I see Shelagh Manton mentioned as an author, would it be possible for
   Shelagh to complete the FSF copyright assignment forms?  Otherwise I
   don't believe we can add ob-lilypond to the Org-mode core, although
   we could still place it in the contrib directory with ob-oz.

2. I see you have a test suite which is fantastic.  Additionally this
   test suite uses ert, which is what the main Org-mode test suite uses.
   Would it be possible to fold this test suite into Org-mode's test
   suite in the testing directory?
   
   If these tests require a lilypond executable we may have to partition
   them off from the main Org-mode test suite so that they can be run
   independently of each other.

I'm happy to continue to push in updates to the Org-mode core as
ob-lilypond development continues.

Thanks to Martyn for this exciting addition! -- Eric

Re: [O] ob-lilypond

[Christian Moe]

This is very doable since it is the first thing I tried on initial
experimentation. I think I had some difficulty cropping the snippet (png)
in that the result had no padding at all, but I'm guessing that can be
overcome.


I guess most of us who would be interested in this would have 
ImageMagick *convert* at hand, if it's difficult to get Lilypond or 
lilypond-book to do it directly.



Certainly with the use cases you suggest, the defaults would need to
change, and C-c C-c would need to act as you describe, but that wouldn't
be an issue if we can define seperate 'modes' for the different ways of
working (I think for now the 'modes' can be considered  mutually exclusive).


I'd tentatively suggest things should be done in a way that is roughly 
analogous with how other Babel languages work, not in the way that 
makes one or another use case super-easy to do. For our different use 
cases we might then each have to tweak some :tangle, :exports, 
:results or :file header arguments.


But using Org-Babel's provisions for system-wide, language-specific 
and buffer-wide heading arguments, the user should be able to define 
her own `modes' by changing a few settings, and avoid littering a 
complex document with those header arguments.


Maybe. Haven't thought this very far through...

Christian

For me it would be great to have Lilypond snippets that can be
evaluated into a linked score image file visible inline the Org
buffer, permanently in #+results: or temporarily as an overlay
(similar to org-preview-latex-fragment).

This is very exciting. I use LilyPond a lot for various projects and I
think integration with orgmode is an obvious solution to a problem I
hope to find very soon!

LilyPond is largely written in Scheme and I'm pretty sure a few of the
devs use emacs. There are some interesting emacs/Lily projects around,
not least Nicolas Sceaux' lyqi-mode which does some pretty groovy
things, including midi keyboard input via rumor.

I'm looking forward to having a chance to play with this. Well done,

Re: [O] ob-lilypond

[Christian Moe]

Hi,

I'm thrilled that Lilypond has been added to Babel, grateful for the 
extra thought given to Mac users -- and completely bowled over by your 
demos!


Rather than put together complex scores or generate arpeggios the 
literate programming way, though, all I'd like to do is to easily 
include simple snippets of music notation in Org documents 
(elaboration follows).


So please consider this a polite request to bump up "Consider the 
option to embed resultant partial musical output into org file" from 
SOMEDAY to TODO in your task list...


Use cases:

- Self-contained documentation, e.g. using Org to author a text like 
the Lilypond documentation: much prose with code examples and the 
results of those examples interspersed.


- Writing a musicology paper, with captioned and cross-referenced 
examples (not /my/ use case, but someone might...)


- Putting together a simple song booklet, such as for a summer camp, 
with lyrics and possibly illustrations. (This is my main interest.)


Ways to do it:

One (imperfect) solution would be a header argument to just surround 
the exported content of Lilypond blocks with the appropriate HTML tags 
/ LaTeX environment for lilypond-book to act on, and perhaps a 
post-processing step to automatically call lilypond-book on the 
exported document. I can probably set up something like this for myself.


But much better, IMO, would be a way to `evaluate' a single Lilypond 
block and get #+RESULTS with a link to a PNG representing just that 
snippet of music. The snippet would then show up in subsequent exports 
as an included graphic without any post-processing, and could also be 
viewed in-buffer with `C-c C-x C-v'. (For my money, this and not 
`tangle all' would be the intuitive use of `C-c C-c' on a block, but I 
understand how your choice makes sense for other uses.)


Yours,
Christian

   - Here is an example Org LilyPond File]] exported as HTML
   - Resultant Score exported in pdf format
   - Generated Score export of individual Pages (png)
*** Modal Cycles (Utilises org-babel and noweb to generate notes)
   - Generated Score
   - Generated Midi File
*** Modal Cycles 2 (Utilises org-babel and noweb to generate notes)
   - Generated Score
   - Generated Midi File
*** Modes in the Key of C (another example of polyglot lilypond programming)
   - Generated Score
   Generated MIDI File

** Features
  - Optional Automated LilyPond Compilation following the "Tangling"
   of a "Literate Org LilyPond" file
  - Optional Automated display of resultant Musical Score following compilation
  - Optional Automated playing of the resultant MIDI file following compilation
  - Highlights syntax errors in Org file following a failed compilation
  - Integrates with LilyPond-Mode
  - Cross-Platform (OSX, nix, win32)

** Usage

*** Compiling lilypond source
Hitting 'C-c C-c' within a lilypond block initiates ly-tangle (tangling of all
lilypond blocks). Depending on the feature settings, ob-lilypond will
then either display a pdf of the score, play the generated midi file,
both, or neither.

'M-x ly-tangle' can also be called from anywhere in the file
and can be tied to a function key with something like...

#+begin_src emacs-lisp

  (global-set-key [f8] 'ly-dev-tangle)

#+end_src

*** Commands

Some commands are included to quickly disable certain post-tangle
activities...
  - ly-toggle-midi-play (toggle whether midi will be played following a
  successful compilation)
  - ly-toggle-pdf-display (toggle whether pdf will be displayed following
 a successful compilation)


NOTE:- If using Timidity for midi playback, kill the midi stream with
C-g in Emacs

** Setup (add to emacs init file)
*** Cloning ob-lilypond

The Files need to be downloaded to your relevant dotfiles directory...

#+BEGIN_SRC sh

git clone https://github.com/mjago/ob-lilypond.git ob-lilypond

#+END_SRC

*** Emacs Initialisation file setup

Require library...
#+BEGIN_SRC emacs-lisp

(add-to-list 'load-path
  (concat dotfiles-dir  "ob-lilypond/lib"))
(require 'ob-lilypond)

#+END_SRC


Add lilypond to your list of babel languages...

I forgot to mention that I leave this decision to Eric, of course.

Indeed -- Lilypond is an old GNU project, I guess there are many Emacs
gnusers.  I would love to include ob-lilypond.el in the next release, it
adds a nice functionality and cannot break anything.

Thanks!

Thanks - I'm no LilyPond expert myself, and so a heads-up from a more 
proficient LilyPond user would be great. Likewise the ins and outs of 
LilyPond-mode. That said, it is working well for me and my use-case, and 
it is great to be generating music and score out of org-mode - it feels a 
good fit, which is testament to the flexability of org-babel and org-mode.

I'll leave that decision to you, but certainly if the software is useful 
to others, I am happy to see it distributed. Actually, I only recently 
discovered how busy Lilypond development is, so there must be potential 
users out there. Perhaps I should bite the bullet and approach the Lilypond
user mailing list to see if there is any interest there?

Hi Martyn,

This looks great, I look forward to testing it out, although my music
composition experience is limited to using Finale in a high-school music
theory class.

It sounds like your plan is to keep this on github during the first
trial and debugging stages.  At some point I would love to include this
into the Org-mode core.

Part of me is tempted to push for immediate integration so that this is
released with Emacs24 (we could push bug fixes throughout the fall),
however this may be too much code for just before an Org-mode release.

Thanks for sharing! -- Eric
