ob-lilypond

[Martyn Jago]

Hi

This is an invitation to try / test ob-lilypond - enabling LilyPond 
Score Generation / Arrangement from within org-mode.

Available on Github at https://github.com/mjago/ob-lilypond

This is a beta release, but includes examples, instructions, and 
tests, and has been tested on OSX and nix.

Any further testing would be helpful.

Following is the readme.org file which is rendered correctly on 
Github...

--->

* Emacs Org Babel LilyPond Mode
** Purpose
Allow LilyPond Score Generation to take place within Emacs Org-mode
using literate programming principles.

** Examples
Several examples are included
*** Misty (Jazz Standard utilising org-mode to organise voice and other data)
      - 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...

#+BEGIN_SRC emacs-lisp
(org-babel-do-load-languages
 'org-babel-load-languages
 '((ruby . t)
   (C . t)
   (emacs-lisp . t)
   (sh t)
   (dot t)
   (clojure t)
   (ditaa t)
   (lilypond t)
   ))

#+END_SRC
 
** Requirements
*** Mac OS X
 - [[http://lilypond.org/][Lilypond]] can be obtained [[http://lilypond.org/][here]]

*** nix
 - Lilypond is available here or via the the package manager
 - For MIDI, [[http://timidity.sourceforge.net/][Timidity]] is available 
[[http://timidity.sourceforge.net/][here]] or via the package manager
 - For PDF, [[http://live.gnome.org/Evince/Downloads][Evince]] is available 
[[http://live.gnome.org/Evince/Downloads][here]] or via package manager

*** Win32
 - Currently untested

** Testing

Tests are provided and can be run by opening
test/ob-lilypond-tests.org and running the following commands...

 - M-x eval-buffer (within ob-lilypond-tests.org
 - M-x ert (t) 

Tests are run automatically on source/test file save if ly-project
(below) has been executed

** Development

Included also is dev/ob-lilypond.org which includes various helper
commands used for development, and the development todo list
 - ly-project (code block - evaluate with C-c C-c and execute M-x ly-project) 
   - load appropriate files
   - set up windows
   - setup project development environment
   - add continuous testing post-save hook
   - map F4 to switch between src or test files to control file (dev/ob-lilypond.org)
   - map F8 to 'ly-dev-tangle (tangle test/test-build/test.org file from anywhere)
 - Remove post-save-hook code block
 - Development todo list

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

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?

Martyn

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!

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

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

Re: ob-lilypond

[Cameron Horsburgh]

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,
and thank you!

I had come across lyqi-mode but haven't checked it out yet. Added to the TODO
list. Thanks for the feedback.

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. 
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).

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).

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.

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...

Yours,
Christian

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

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.

There is little chance to get the assignement before the release of 7.6,
so yes, let's take that route (contrib/) for now.

This is now located in contrib/babel/langs.

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.

They don't.

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
increased participation later-on in the project.  Please let me know
(soon) if you would like me to make this change.

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.

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
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'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.

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

It looks like noweb parsing has very recently become very brittle, 
since it broke the noweb in my lilypond example. 
This does not appear to be restricted to lilypond blocks.

The error is (wrong-type-argument consp nil)

I fixed for my songs by changing...

#+srcname: gen_arpeggio(key,root)

to...

#+srcname: gen_arpeggio (key,root)

and... 

<<gen_arpeggio(key="c",root="c")>>

to...

<<gen_arpeggio (key="c",root="c")>>

I believe #+call: is affected too.

Unfortunately I won't be able to investigate further until next week.

Martyn

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.

Thanks again for this great contribution -- Eric

** define a block with a name for noweb expansion
   :PROPERTIES:
   :tangle:   yes
   :noweb:    yes
   :END:

#+source: simple(something="something")
#+begin_src emacs-lisp
  something
#+end_src

another block including the first block
#+begin_src emacs-lisp
  <<simple(something="something else")>>
#+end_src

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")

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):

Am I missing something?

Thanks for any help!

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/)

HTH,

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
