Input arguments (flags):
The following arguments are mutually exclusive (pick only one):
-g GLYPHS, --glyphs-path GLYPHS
Path to .glyphs source file
-u UFO [UFO ...], --ufo-paths UFO [UFO ...]
One or more paths to UFO files
-m DESIGNSPACE, --mm-designspace DESIGNSPACE
Path to .designspace file
Input arguments (positonal):
Alternatively, guess source format from filename extension
INPUTS Either one *.designspace or *.glyphs file, or one or more *.ufo
Other input arguments:
--glyph-data GLYPHDATA
Custom GlyphData XML file with glyph info (production name, script, category,
subCategory, etc.). Can be used more than once (for Glyphs sources only).
Output arguments:
-o FORMAT [FORMAT ...], --output FORMAT [FORMAT ...]
Output font formats. Choose 1 or more from: ufo, otf, otf-cff2, ttf,
ttf-interpolatable, otf-interpolatable, variable, variable-cff2. Default: otf, ttf.
(No file paths).
--output-path OUTPUT_PATH
Output font file path. Only valid when the output is a single file (e.g. input is a
single UFO or output is a single variable font)
--output-dir OUTPUT_DIR
Output folder. By default, output folders are created in the current working
directory, grouping output fonts by format.
-i [INSTANCE_NAME], --interpolate [INSTANCE_NAME]
Interpolate masters and generate all the instances defined. To only interpolate a
specific instance (or instances) that match a given "name" attribute, you can pass
as argument the full instance name or a regular expression. E.g.: -i "Noto Sans
Bold"; or -i ".* UI Condensed". (for Glyphs or DesignSpace sources only).
--variable-fonts [VARIABLE_FONT_FILENAME]
Filter the list of variable fonts produced from the input Designspace file. By
default all listed variable fonts are generated. To generate a specific variable
font (or variable fonts) that match a given "filename" attribute, you can pass as
argument the full filename or a regular expression. E.g.: --variable-fonts
"MyFontVF_WeightOnly.ttf"; or --variable-fonts "MyFontVFItalic_.*.ttf".
-M, --masters-as-instances
Output masters as instances
--family-name FAMILY_NAME
Family name to use for masters, and to filter output instances
--round-instances
Apply integer rounding to all geometry when interpolating
--designspace-path DESIGNSPACE_PATH
Path to output designspace file (for Glyphs sources only).
--master-dir MASTER_DIR
Directory where to write master UFO. Default: "./master_ufo". If value is "{tmp}",
a temporary directory is created and removed at the end (for Glyphs sources only).
--instance-dir INSTANCE_DIR
Directory where to write instance UFOs. Default: "./instance_ufo". If value is
"{tmp}", a temporary directory is created and removed at the end (for Glyphs
sources only).
--no-write-skipexportglyphs
Do not store the glyph export flags in the 'public.skipExportGlyphs' key of
designspace/UFO lib, but use the old private glyph lib key
'com.schriftgestaltung.Glyphs.Export' (for Glyphs sources only).
--validate-ufo
Enable ufoLib validation on reading/writing UFO files. It is disabled by default
--check-compatibility
Check if the source files are interpolatable. It is disabled by default, but
enabled when building variable fonts or what the 'Enforce Compatibility Check'
custom parameter is set on a Glyphs file
--no-check-compatibility
Turns off the compatibility checker even when building variable fonts
--expand-features-to-instances
Resolves all include()s in the master feature file and writes the full feature file
to all instance UFOs. Only valid when interpolating. Use if you share feature
files of masters in external files, as instances can end up elsewhere.
--fea-include-dir FEA_INCLUDE_DIR
Overrides the default directory where to search for included feature files with
relative paths. This only works when the input is a Designspace or UFOs, not from
Glyphs at the moment.
--no-generate-GDEF
Do not auto-generate a GDEF table, but keep an existing one intact.
--save-ufo-as-zip
Deprecated. Use --ufo-structure=zip instead.
--ufo-structure {package,zip,json}
Select UFO format structure. Choose between: package, zip, json (default: package).
NOTE: json export is unofficial/experimental.
--indent-json
Whether to format the JSON files created with --ufostructure=json as multiple lines
with 2-space indentation. Default: single line, no indent.
Handling of contours:
--keep-overlaps
Do not remove any overlap.
--overlaps-backend BACKEND
Select library to remove overlaps. Choose between: booleanOperations, pathops
(default: booleanOperations)
--keep-direction
Do not reverse contour direction when output is ttf or ttf-interpolatable
--ttf-curves {cu2qu,mixed,keep-quad,keep-cubic}
Controls conversion of cubic B??zier curves to TrueType quadratic splines. By
default ('cu2qu'), all cubics are converted to quadratic (glyf v0). With 'mixed',
cubics are converted to quadratic only when more economical. If 'keep-quad' or
'keep-cubic', cu2qu is skipped altogether and curves are compiled unchanged. NOTE:
cubics in TTF use glyf v1 which is still draft!
-e ERROR, --conversion-error ERROR
Maximum approximation error for cubic to quadratic conversion measured in EM
-f, --flatten-components
Flatten nested components to single level.
-a [AUTOHINT], --autohint [AUTOHINT]
Run ttfautohint. Can provide arguments, quoted. By default, ttfautohint is run if
the (.glyphs) source contains a 'TTFAutohint options' instance custom parameter.
This option overrides that. See --noautohint to disable.
-A, --no-autohint
Do not run ttfautohint, even if source contains a 'TTFAutohint options' custom
parameter
--cff-round-tolerance FLOAT
Restrict rounding of point coordinates in CFF table to only those floats whose
absolute difference from their integral part is less than or equal to the
tolerance. By default, all floats are rounded to integer (tolerance 0.5); 0
disables rounding.
--optimize-cff OPTIMIZE_CFF
0 disables all optimizations; 1 specializes the CFF charstring operators; 2
(default) also enables subroutinization
--subroutinizer {compreffor,cffsubr}
name of the library to use for compressing CFF charstrings. Choose between:
compreffor, cffsubr. By default compreffor is used for CFF 1, and cffsubr for CFF2.
NOTE: compreffor doesn't support CFF2.
--no-optimize-gvar
Do not perform IUP optimization on variable font's 'gvar' table. (only works with
'variable' TrueTypeflavored output)
--filter CLASS
string specifying a filter class to load, either built-in or from an external
module, optionally initialized with the given keyword arguments. The class and
module names are separated by '::'. The option can be repeated multiple times for
each filter class. The option overrides the filters specified in the UFO lib. You
can use an ellipsis --filter='...' to keep the latter and insert additional
--filter(s), either before or after it.
--no-auto-use-my-metrics
Don't automatically set USE_MY_METRICS glyf component flags (0x0200).
--drop-implied-oncurves
drop on-curve points that can be implied when exactly in the middle of two
off-curve points (TrueType only; default: False).
Handling of OpenType Layout:
--interpolate-binary-layout [MASTER_DIR]
Interpolate layout tables from compiled master binaries. Requires Glyphs or
DesignSpace source.
--feature-writer CLASS
string specifying a feature writer class to load, either built-in or from an
external module, optionally initialized with the given keyword arguments. The class
and module names are separated by '::'. The option can be repeated multiple times
for each writer class. A special value of 'None' will disable all automatic feature
generation. The option overrides both the default ufo2ft writers and those
specified in the UFO lib. You can use ellipsis --featurewriter='...' to keep the
latter and insert additional --feature-writer(s) either before or after those.
--debug-feature-file FILE
Path were to dump OpenType features text to debug auto-generated features (kern,
mark, mkmk, etc.).
--no-variable-features
Disable generation of variable FEA in ufo2ft when compiling VFs; instead build
separate OT layout tables for each master and merge them with varLib.
--mti-source MTI_SOURCE
mtiLib feature definition .plist file path (use instead of FEA)
Logging arguments:
--timing
Print the elapsed time for each steps
--verbose LEVEL
Configure the logger verbosity level. Choose between: DEBUG, INFO, WARNING, ERROR,
CRITICAL. Default: INFO
