2.4 Font Directories

+ + + + + +

groff enforces few restrictions on how font description files are +named. For its family/style mechanism to work (see Font Families), +the names of fonts within a family should start with the family name, +followed by the style. For example, the Times family uses ‘T’ for +the family name and ‘R’, ‘B’, ‘I’, and ‘BI’ to +indicate the styles ‘roman’, ‘bold’, ‘italic’, and ‘bold italic’, +respectively. Thus the final font names are ‘TR’, ‘TB’, +‘TI’, and ‘TBI’. +

+ + +

Font description files are kept in font directories, which +together constitute the font path. The search procedure +always appends the directory devname, where name is +the name of the output device. Assuming TeX DVI output, and +/foo/bar as a font directory, the font description files for +grodvi must be in /foo/bar/devdvi. +Each directory in the font path is searched in the following order until +the desired font description file is found or the list is exhausted. +

Directories specified with GNU troff’s or groff’s +-f command-line option. All output drivers (and some +preprocessors) support this option as well, because they require +information about the glyphs to be rendered in the document. + +
+Directories listed in the GROFF_FONT_PATH environment variable. + +
+ +A site-local directory and the main font description directory. +The locations corresponding to your installation are listed in section +“Environment” of gtroff(1). If not otherwise configured, +they are as follows. + +
+
```
/usr/local/share/groff/site-font
+/usr/local/share/groff/1.23.0/font
+
```
+ +
The foregoing assumes that the version of groff is 1.23.0, and +that the installation prefix was /usr/local. It is possible to +fine-tune these locations during the source configuration process. +
