Hi, I'm experimenting with MediaWiki's Score extension. The current version of the Score extension, 0.2, runs lilypond with -dsafe="#t" (and not --jail) which is quite restrictive. Would it be conceivable to make more Scheme-symbols public in safe mode in future versions of LilyPond?
Example: ly:breathing-sign::divisio-maxima etc cannot be used. A better solution would be to convince the Score-developer to use --jail but this would perhaps demand too much from the server owner? I also don't have any control over the version of LilyPond that is installed on the server (typically not so recent) and Score does not attempt to convert the input file so files may break when the version changes. I will ask the Score developer to use convert-ly in the next version. Until then, it could be useful to write ly-files that are sensitive to the version of lilypond. Moreover, even if a conversion is in place, it would be useful to access more recent features if present. Thus, I have two scenarios: 1) I would like to use certain features if they are available (version >=2.16 say) \version "2.14.2" if version >= 2.16 then lily-code fi 2) Manually convert between versions \version "2.14.2" if version >= 2.16 then converted lily-code else old lily-code fi Since the lily-code is running in safe-mode, as mentioned above, there is a very limited repertoire of scheme code that can be used (e.g. ly:parser-include-string cannot be used). Is such conditional lily-code possible to write? In safe mode?
