# 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”

-display name

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

-help

  Bring up a browser looking at this documentation.

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

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

-version

  Prints out the source version and exits.

-last

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

-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)).

-skippyfile

  Do not execute python init scripts. These can be run later using the `fontforge.runInitScripts()` Python method.

-skippyplug

  Do not load (enabled) Python plugins. These can be loaded later via the Configure Plugins dialog or the `fontforge.loadPlugins()` Python method.

-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

## 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.
