vftovp - convert virtual font (vf) files to virtual property lists (vpl)

vftovp [ -charcode-format =format ] [

-verbose ] vf_name[.vf]tfm_name[.tfm][ vpl_name[.vpl]]

This manual page is not meant to be exhaustive. The complete documentation for this version of \*(TX can be found in the info file or manual "Web2C: A TeX implementation" .

The

vftovp program translates a (program-oriented) virtual font file and its accompanying \*(TX font metric file to a (human-oriented) property list file. Thus, the virtual font can be edited, and its exact contents can be displayed mnemonically. It also serves as a VF-file validating program; if no error messages are given, the input files are correct.

The filenames are extended with the appropriate extension if necessary.

The argument formatto

-charcode-format specifies how character codes are output in the VPL file. By default, only letters and digits are output using the

C integer code (i.e., in ASCII); the others are output in octal. (Unless the font's coding scheme starts with

TeX math sy or

R when all are output in octal.) If formatis

R ascii , all character codes that correspond to graphic characters, besides the left and right parentheses, are output in ASCII. On the other hand, if formatis

R octal , all character codes are output in octal.

Without the

-verbose option,

vftovp operates silently. With it, a banner and progress report are printed on stdout .

vftovp looks for vf_nameusing the environment variable VFFONTS. If that is not set, it uses the variable TEXFONTS. If that is not set, it uses the system default.

Donald E. Knuth wrote the program, based in part on an idea of David Fuchs, starting with the code for

R tftopl (1). Karl Berry adapted it for compilation with

R web2c .
