LilyPond parser as standalone

[s9vahahn]

Hello,

i have a question concerning the parser of LilyPond. I would like to  
use it as standalone, so I can do some analysis on its AST  
representation (i.e. the music expression tree):

From the received AST I would like to read out all notation relevant  
data e.g. notes, durations, beginnings and endings of slurs,  
articulations, dynamics, etc. in order to do some analysis on this data.

The analysis is something like "find all exact repetitions of notes of  
length 5". Then I would like to adapt the AST, i.e. change note  
durations etc., and to serialize the modified AST back into LilyPond.

Since I do not know scheme and the documentation of the parser and its  
code are quite limited I just want to know whether it is easy to use  
the parser in a standalone analysis or whether the music expression or  
context tree is not suited for such a procedure?


Best,
Anna
