grcompiler - Compile GDL into a TrueType Font
SYNOPSIS
grcompiler [-d] [-D] [-g] [-n number] [-v number] [-w number] [-wall] [-q] gdl-file font-file [output-file] [output-fontname]
Description
Grcompiler compiles a Graphite Description Language description of the smarts for a font along with a TrueType Font to create a graphite
font with graphite tables in it.
-d Generate XML debugger file.
-D Generate all debugger files.
-g Permit and ignore invalid glyph definitions.
-nnumber
Set name table start location.
-q Quiet mode (no messages except on error).
-vnumber
Set Silf table version number.
-wnnnn Ignore warning with the given number. This option may be repeated.
-wall Display all warnings.
Environment
grcompiler makes use of the following environment variables
GDLPP Specifies the command to execute to run the GDL preprocessor
Files
gdlerr.txt
Warnings and errors are output to this file.
dbg_classes.txt
Debug file that specifies the classes stored in the font in terms of their GDL source and containing glyph ids in hex.
dbg_cmap.txt
Debug file giving Unicode to glyph mapping of all the glyphs in the font and vice versa.
dbg_enginecode.txt
Debug file containing the action code and constraint code associated with each pass and rule in a pass.
dbg_fsm.txt
Debug file that gives the finite state machines of each pass and the rules referenced. For each pass, a mapping is given between
glyph and column number.
dbg_glyphattrs.txt
Debug file containing all the glyph attributes and their names, along with values specified for each glyph.
dbg_parsetree.txt
Debug file giving the complete parse tree of the GDL source file.
dbg_ruleprec.txt
Debug file that lists the rules in precedence order (order in which they will be tested) for each pass.
$_temp.gdl
Debug file containing the output of gdlpp

Font::TTF::Loca(3) User Contributed Perl Documentation Font::TTF::Loca(3)NAME
Font::TTF::Loca - the Locations table, which is intimately tied to the glyf table
DESCRIPTION
The location table holds the directory of locations of each glyph within the glyf table. Due to this relationship and the unimportance of
the actual locations when it comes to holding glyphs in memory, reading the location table results in the creation of glyph objects for
each glyph and stores them here. So if you are looking for glyphs, do not look in the "glyf" table, look here instead.
Things get complicated if you try to change the glyph list within the one table. The recommendation is to create another clean location
object to replace this table in the font, ensuring that the old table is read first and to transfer or copy glyphs across from the read
table to the new table.
INSTANCE VARIABLES
The instance variables do not start with a space
glyphs
An array of glyph objects for each glyph.
glyphtype
A string containing the class name to create for each new glyph. If empty, defaults to Font::TTF::Glyph.
METHODS
$t->new
Creates a new location table making sure it has a glyphs array
$t->read
Reads the location table creating glyph objects (Font::TTF::Glyph) for each glyph allowing their later reading.
$t->out($fh)
Writes the location table out to $fh. Notice that not having read the location table implies that the glyf table has not been read either,
so the numbers in the location table are still valid. Let's hope that "maxp/numGlyphs" and "head/indexToLocFmt" haven't changed otherwise
we are in big trouble.
The function uses the OUTLOC location in the glyph calculated when the glyf table was attempted to be output.
$t->out_xml($context, $depth)
No need to output a loca table, this is dynamically generated
$t->glyphs_do(&func)
Calls func for each glyph in this location table in numerical order:
&func($glyph, $glyph_num)
BUGS
None known
