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
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 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 format
to -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 TeX math ex, when all are output
in octal.) If format is ascii, all character codes that correspond to
graphic characters, besides the left and right parentheses, are output
in ASCII. On the other hand, if format is 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_name using the environment variable VFFONTS. If that
is not set, it uses the variable TEXFONTS. If that is not set, it uses
the system default.
See tex(1)
for the details of the searching.

Donald E. Knuth wrote the program,
based in part on an idea of David Fuchs, starting with the code for tftopl(1)
.
Karl Berry adapted it for compilation with web2c.
