dumpfont - dump table structures from Font::TTF::Font

# [SYNOPSIS](#SYNOPSIS)

```
  dumpfont [-t taglist] [-a attach.xml] [-v voltsource.vtp] [-d] font.ttf
```

Opens the fontfile with Font::TTF::Font->open and then uses Data::Dumper to pretty-print the resultant data structures for one or more font tables to STDOUT.

"taglist" is a comma-or space-separated list of tags specifying which tables to dump. If -a is supplied then "taglist" may contain 'AP' to request dump of the attachment point structure. If -v is supplied or the tables to dump includes the 'TSIV' table, then the VOLT source will first be parsed then dumped. If -t not provided, dumps all tables. If "taglist" contain 'woff' then the metadata from WOFF-formatted fonts will be dumped.

Normally dumpfont minimizes output by crossreferencing previously dumped structures, but this can make it difficult to diff two fonts. -d suppresses this behavior except where needed to break reference cycles.

By design, dumpfont silently ignores any ' PARENT' or ' CACHE' elements, as well as any element whose value is a Font::TTF::Font object, in any of the data structures.
