NAME¶

grcompiler - Compile GDL into a TrueType Font

SYNOPSIS¶

grcompiler
[-c] [-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.

-c

Enable compression of Graphite tables. This forces a version 5.0 Silf and version 3.0 Glat.

-d

Generate XML debugger file.

-D

Generate all debugger files.

-g

Permit and ignore invalid glyph definitions.

-n number

Set name table start location.

-q

Quiet mode (no messages except on error).

-v number

Set Silf table version number.

-w number

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
