= Ruby font installer library These files should help you (a programmer) to create a font installer for TeX. The library is currently in alpha state. The interface might change, but a lot of basic classes and methods are available. See the example programs in the examples directory on how to use the library. Also take a look at the Kpathsea and ENC classes on how to make use of these. == Roadmap Accessing Encodings:: See the ENC class to read and write <tt>.enc</tt>-files. Accessing TFM/VF files:: Use the TFM and VF classes to read and write TeX font metrics and virtual fonts. Accessing font metrics:: See the FontMetric class and the subclass AFM to read and write the font metric files. Installing a font(set):: See below for examples. == Example programs You might find the examples shipped with RFIL useful. afm2tfm.rb:: Install a single font. As with afm2tfm (the program shipped with dvips), you can reencode a font and fake caps. afminfo:: Give information about an afm file (metrics, glyph information). encodingtable:: Print out a table with encodings/glyphnames/slots pldiff:: Compare two metric files and output all differences. plinfo:: Show information about a TeX metric file. rfont:: Simple installer that handles a family of fonts (reguar, italic, bold...) rfii:: Yet another installer, work in progress. == Example usage of the RFI Library === Example usage to install a single font: font=Font.new font.load_variant("savorg__.afm") font.texenc=["ec","texnansi"] font.mapenc=["8r"] font.write_files This will create virtual fonts for _ec_ and _texnansi_ encoding that map to <em>8r</em> encoding, +tfm+ files for the _raw_ fonts and a +map+-file. === Synthesize small caps Create a second variant, synthesize small caps and copy the relevant part to the main font. f=Font.new f.texenc="ec" f.load_variant("savorg__.afm") fc = f.load_variant("savorg__.afm") f.fake_caps(fc,0.8) f.copy(fc,:lowercase,:ligkern=>true) f.defaultfm.chars.apply_ligkern_instructions(RFI::STDLIGKERN) f.write_files == Installation Run <tt>ruby setup.rb config</tt> and afterwards <tt>ruby setup.rb install</tt> to install the library files in your system. You might need to be superuser/root for that. Now you should be able to use the examples. Perhaps start with <tt>afminfo</tt> or <tt>rfont</tt>. == Creating the documentation Run <tt>rake rdoc</tt> in order to create the documentation in the subdirectory <tt>doc/</tt>. Open <tt>doc/index.html</tt> in your browser and voila, see all classes and methods documented. If you don't have <tt>Rake</tt> installed, go to the homepage (see below) and read the online documentation. ==Other Stuff Author:: Patrick Gundlach <firstname.lastname@example.org> Project Page:: https://foundry.supelec.fr/projects/rfil Homepage:: (Documentation) https://rfil.groups.foundry.supelec.fr License:: Copyright (c) 2005 Patrick Gundlach.

rfil – Ruby font installer library
The Ruby font installer library (RFIL) is another attempt on font installation for TeX fonts. It consists of a set of example programs and several libraries for doing font related tasks, such as read/write tfm, afm, vf and enc files, creating font metrics, doing calculations and the like. The software is all written in Ruby.
