3.4 Updating files with convert-ly
The LilyPond input syntax is routinely changed to simplify it or improve
it in different ways. As a side effect of this, the LilyPond interpreter
often is no longer compatible with older input files. To remedy this,
the program convert-ly
can be used to deal with most of the
syntax changes between LilyPond versions.
It uses \version
statements in the input files to detect the
old version number. In most cases, to upgrade your input file it is
sufficient to run
convert-ly -e myfile.ly
MacOS X users may execute this command under the menu entry
Compile > Update syntax
.
If there are no changes to myfile.ly and file called myfile.ly.NEW is created, then myfile.ly is already updated.
