2.1 Why does the syntax change?
The LilyPond input syntax occasionally changes. As LilyPond itself improves, the syntax (input language) is modified accordingly. Sometimes these changes are made to make the input easier to read and write or sometimes the changes are made to accommodate new features of LilyPond.
For example, all \paper and \layout property names
are supposed to be written in the form first-second-third.
However, in version 2.11.60, we noticed that the
printallheaders property did not follow this convention.
Should we leave it alone (confusing new users who must deal with
an inconsistent input format), or change it (annoying old users
with existing scores)? In this case, we decided to change the
name to print-all-headers. Fortunately, this change can be
automated with our convert-ly tool.
Unfortunately, convert-ly cannot handle all input changes.
For example, in LilyPond 2.4 and earlier, accents and non-English
letters were entered using LaTeX – displaying the French word for
Christmas was entered as No\"el. But in LilyPond
2.6 and above, the special ë must be entered directly into
the LilyPond file as an UTF-8 character. convert-ly cannot
change all the LaTeX special characters into UTF-8 characters; you
must manually update your old LilyPond input files.
