Command Line Arguments

$ fontforge [-options] [filenames]
$ fontforge [-script] scriptfile [arguments]
$ fontforge -c script-string [arguments]

The filenames may specify any number of files in one of the font formats that FontForge recognizes (various postscript formats, truetype, opentype, mac resource, bitmap, svg, etc.).

Some files (.ttc or mac resource) may contain more than one outline font. You may pick which font you want by following the filename with the fontname in parentheses, thus:

$ fontforge "gulim.ttc(GulimChe)"

will select the font GulimChe out of the font file gulim.ttc.

FontForge recognizes the following options:

-allglyphs

Load all glyphs from the ‘glyf’ table of a ttc file, rather than the subset used in the selected font. (Note that if a ttc file contains multiple ‘glyf’ tables, only one will be loaded, but that one will be completely loaded).

-c script-string

If FontForge’s first (or second, if the first is -lang) argument is “-c” then the argument that follows will be treated as a string containing scripting commands, and those commands will be executed. All remaining arguments will be passed to the script.

$ fontforge -c 'Open($1); Generate($2)' foo.sfd foo.ttf

Will read a font from “foo.sfd” and then generate a truetype font from it called “foo.ttf”

-cmap type

Where type may be     Current | Copy | Private Gives the user some control over colormap handlingon 8bit screens.

-depth val

Specifies that FontForge should search for a visual with the given depth

-display name

Specifies the name of the display on which FontForge will open its windows

-dontopenxdevices

Various people have complained that when FontForge attempts to open the devices of the wacom graphics tablet, the X server gives a BadDevice error. I can’t duplicate this, the open works fine on my system, but this argument allows them to tell fontforge not to try to use the tablet.

-help

Bring up a browser looking at this documentation.

-lang={py ff}
-lang {py ff}

Specifies whether the script should be interpretted as a python script or a fontforge script.

-version

Prints out the source version and exits.

-keyboard type

Where type may be     ibm | mac | sun | ppc | 0 | 1 | 2 | 3 Allows you to specify the type of keyboard. Currently this is only relevent when generating menus. The modifier keys are in different locations on different keyboards (under different operating systems) and if FontForge knows what keyboard you are using it can make the hot-keys have better labels.

  • ibm | 0 Uses the Control and Alt keys
  • mac | 1 Uses the Control and Option keys (Mac OS/X, Mac keyboard)
  • ppc | 3 Uses the Control and Command keys (Suse ppc linux, Mac keyboard)
  • sun | 2 Uses the Control and Meta keys

-last

Opens the last sfd file closed. If used more than once will open the last several sfd files.

-library-status

Writes info about the status of optional libraries to stderr. Including: Whether the library exists on this system, whether ff can use it, and an URL from which the library can be found.

-new

Creates a new font.

-nosplash

FontForge will not display its splash screen on startup (for slow connections)

-open

Bring up an open font dialog

-quit

Exit fontforge (only useful if -unique is passed as well, in which case the master fontforge will be asked to exit)

-recover type

Where type may be:

none

Do not attempt any automatic file recovery

clean

Clean out the directory containing files to be recovered

auto

recover any files which have been changed but which fontforge crashed on before saving.

-script script-file

If FontForge’s first argument is “-script” then the argument that follows will be treated as a script file and all the remaining arguments will be passed as arguments to that file. (The “-script” argument may be omitted, and if the first argument is an executable file which whose first line starts with “#!” and contains “fontforge”. This means that fontforge may be used as an interpreter. Ie. you can create a fontforge script file and type its name to your shell and fontforge will be invoked to process that file as a script file (passing any arguments to it)).

-sync

Do synchronous screen drawing. Slows things down, makes some things easier to debug.

-unique

If there is already a fontforge running on this screen, then the current version will pass its arguments to the already existing one for it to open, and then the current version will exit. So it looks more like a Mac/Windows app.

-usage

Display a brief description of the options

-vc type

Where type may be: StaticGray GrayScale StaticColor PsuedoColor TrueColor DirectColor (See the X manuals for a description of what these mean). FontForge will search through the visuals in an attempt to find one with the desired VisualClass (given here) and depth (given with the -depth option).

Environment Variables

FontForge examines the following environment variables:

BROWSER

Specifies the name of a browser program for examining documentation (must be able to read a local or remote html file and display it reasonably). On CygWin systems browsers that work in the windows world (as opposed to the cygwin sub-system) must be specified by a full path spec.

AUTOTRACE

Specifies the name and location of the autotrace program. (if not specified FontForge will try to find it in the user’s path)

POTRACE

Specifies the name and location of the potrace program.

MF

Specifies the name and location of the metafont program. (if not specified FontForge will try to find it in the user’s path)

FONTFORGE_VERBOSE

Turns on verbose mode in script execution (the script will be printed to stdout as it is executed).

FONTFORGE_LOADPREFS

Controls loading of preference items. If set to “Always” then preferences will be loaded even for scripts. If set to “Never” then preferences will not be loaded unless explicitly requested. If unset (or if set to any other value) then preferences will be loaded when ff starts up with a user interface, and will not be loaded if ff starts up executing a script.

FONTFORGE_LANGUAGE

Provides a default interpreter to use when executing a script. Must be either “py” or “ff”/”pe”.


LANG, LC_ALL, etc.

To determine the current locale, etc.

PATH

Used when looking for Autotrace or mf programs

TMPDIR

Temporary directory. Used for temporary files for which I need a filename (ie. to pass to autotrace, etc.)

HOME

Used to figure out where to put the .FontForge directory which includes user preferences and the recovery files.

USER

Used to create comments in new fonts about who created the font, or who saved it.
