xgfmerge - merges two Xgridfit program files


xgfmerge [options] file-a file-b [...]


Xgfmerge merges two or more Xgridfit program files, where file-a is a program generated
automatically from an existing font using TTX and ttx2xgf, and file-b and any other files
in the list contain other programming for the font. Xgfmerge outputs the merged
programming to stdout. To capture the output in a file, use this syntax:

$xgfmerge -o merged-file.xgf file-a.xgf file-b.xgf

Note: To merge Xgridfit instructions with those already in a font, the best method is now
to run Xgridfit in merge-mode (option -m).


-c Look for a <default type="compile-globals"/> element in each file after the first
in the list. If value="no" then ignore all <default>, <control-value>, <function>,
<macro> and <pre-program> elements in the file.

-h Display a help message.

-n Merge <no-compile> elements from all files. <glyph> elements with duplicate "ps-
name" attributes are ignored.

-o file
The file to write the output to. If this option is not used, output is written to

-p When a <pre-program> element in a file other than file-a is available, use it
instead of the one from file-a. If this option is not present, xgfmerge merges the
programming in the <pre-program> of file-a with that in the <pre-program> of
whichever file is being merged at the moment. The result is unlikely to be good if
a single run of xgfmerge merges the contents of more than two <pre-program>

-s Sort <glyph> elements in the output file into alphabetical order.

-v Verbose output: xgfmerge tells you what it is doing at each step.

-x Resolve XIncludes before merging all files in the list except for file-a. Any
XIncludes from file-a.xgf are stripped out of the files before this operation is
performed. If XInclude is used to bring global elements (<control-value>,
<function>, etc.) into these files, it is probably a good idea to use the -c option
as well.
