Hello, I have corrected a lot of bugs on this point in GregorioTeX and LuaTeX, and now it reached a point where it can be more widely used. There are three main advantages of using LuaTeX over lamed:
- it can produce PDF directly with the command pdflualatex - it can use .otf and .ttf fonts without any configuration - it removes some bugs in gregorio, and automatically adds an hyphen at the end of scores lines when needed To use gregorio with LuaTeX at full power you need the latest svn version of the GregorioTeX files (a lot of bugs were fixed very recently thanks to Abbot Jaques Peron), and the latest version of the additional files for LuaTeX. You can find these additional files here : http://norgz.guiling.fr/gregorioluatex/ in the file luaadditionalfiles.zip. You just have tu unzip it, copy it in a directory accessible to TeX and call mktexlsr. If you already had some of these files, they should be removed before. Once you have this set up, you can use Gregorio with otf fonts by typing directly utf8 characters. Some packages of LaTeX don't work with LuaTeX, for example inputenc. To make it work you must call the package luainputenc instead, with the same options. It automatically calls inputenc when called with a traditional LaTeX (with lamed for example), so you can safely change your documents to use it. There are still some minor problems when mixing otf and non-otf fonts, especially on the accents. The file test.tex in the directory shows a very simple example on how to use an otf font (the font is in the directory too, it's a free font). The syntax to call a new font is the same as in XeTeX, if you don't want to learn it, simply remember the options in the file test.tex, they are OK with 99.9% of the fonts. The rule for inputenc is the following one: if you use otf fonts, don't use inputenc nor luainputenc, and if you use traditional fonts, use luainputenc. Please tell me if you encounter any problem. Also I did a logo for gregorio, in the attached file, please don't let me win the logo contest ;) Thank you, -- Elie
