Automatic Feature Generation
Glyphs can automatically generate many OpenType features if it finds glyphs with certain names in the font.
| Tag | Name | Description |
|---|---|---|
| All Alternatives | Glyphs automatically builds the |
| Standard Ligatures | Join the glyph names of the components with an underscore (_).
Some common ligatures (f_f_i, f_f_l, f_f, fi, fl, lu_lakkhangyao-thai, ru_lakkhangyao-thai) are automatically placed in the |
| Discretionary Ligatures | Join the glyph names of the components with an underscore (_), for example, f_odieresis. |
| Historical Ligatures | Ligatures with longs, or with a .hlig or .hist suffix. |
| Required Ligatures | Add .rlig to the ligature name. Also triggered by lam_alef-ar, lam_alefHamzaabove-ar, lam_alefHamzabelow-ar, lam_alefMadda-ar, lam_alef-ar.fina, lam_alefHamzaabove-ar.fina, lam_alefHamzabelow-ar.fina, lam_alefMadda-ar.fina, lam_alefWasla-ar, lam_alefWasla-ar.fina. |
| Small Capitals from Capitals | Add .sc, .c2sc, or .smcp to the glyph name.
For separate sets for |
| Small Capitals | Add .sc or .smcp to the glyph name. |
| Petite Capitals from Capitals | Add .pc, .c2pc, or .pcap to the glyph name. |
| Petite Capitals | Add .pc or .pcap to the glyph name. |
| Superscript | Add .sups to the glyph name. Or extend figure names with superior, without the period, for example, onesuperior. |
| Subscript | Add inferior, .sinf or .subs to the glyph name. If the font does not differentiate between subscript and scientific inferior, use one set of .subs glyphs, and Glyphs will create both features with it. |
| Scientific Inferiors | Add inferior, .sinf or .subs to the glyph name. |
| Alternative Fractions | Add figures, slash, and any of these nut fraction glyphs to the font: oneovertwo, zerooverthree, oneoverthree, twooverthree, oneoverfour, threeoverfour, oneoverfive, twooverfive, threeoverfive, fouroverfive, oneoversix, fiveoversix, oneoverseven, twooverseven, threeoverseven, fouroverseven, fiveoverseven, sixoverseven, oneovereight, threeovereight, fiveovereight, sevenovereight, oneovernine, twoovernine, fourovernine, fiveovernine, sevenovernine, eightovernine, oneoverten, threeoverten, sevenoverten, nineoverten, oneovereleven, twoovereleven, threeovereleven, fourovereleven, fiveovereleven, sixovereleven, sevenovereleven, eightovereleven, nineovereleven, tenovereleven, oneovertwelve, fiveovertwelve, sevenovertwelve, elevenovertwelve, oneoveronehundred. |
| Fractions | The frac feature is generated from the .numr, .dnom, and fraction glyphs.
If they are not present in the font, then the feature will be composed of any pre-built fractions mentioned in the |
| Denominators | Add .dnom to the glyph name. |
| Numerators | Add .numr to the glyph name. |
| Oldstyle Figures | Add .osf (for proportional oldstyle figures) or .tosf (for tabular oldstyle figures) to the glyph name. Can be applied to other characters as well, for example, currency signs. |
| Tabular Figures | Add .tf (for tabular figures) or .tosf (for tabular oldstyle figures) to the glyph name. Can be applied to other characters as well, for example, currency signs. Do not use the figure suffix for the default figures; for example, if the default figures are proportional oldstyle figures, do not use figures with a .osf suffix. |
| Proportional Figures | Add .osf (for proportional oldstyle figures) or .lf (for proportional lining figures) to the glyph name. Can be applied to other characters as well, for example, currency signs. |
| Lining Figures | Add .lf (for proportional lining figures) or .tf (for tabular figures) to the glyph name. Can be applied to other characters as well, for example, currency signs. |
| Ordinals | Automatically built if default figures, numero, ordfeminine, and ordmasculine are found in the font. |
| Ornaments | Add .ornm to the glyph name of letters A–Z or a–z. Also, make sure the bullet glyph is in the font. |
| Historical Forms | Add .hist to the glyph name. |
| Uppercase Forms | Add .case to the glyph name or .lf to the name of a figure. |
| Capital Spacing | Add uppercase letters to the font, and choose Capital Spacing from the plus menu in the bottom-left of File → Font Info… → Features. |
| Localized Forms | Add .loclXXX to the glyph name, where XXX represents the three letter language tag, for example, .loclENG for English, or .loclSVE for Swedish. There is also a built-in list of glyphs that trigger localizations:
|
| Character Variants | Add .cv01 through .cv99 to the glyph name. Note that the OpenType spec recommends grouping related alternative glyphs into the same feature. Use manual feature code if there are multiple alternatives for a glyph; for example, place the following code in a single |
| Stylistic Set | Add .ss01 through .ss20 to the glyph name. Stylistic sets can be named. |
| Stylistic Alternates | By default, Glyphs will duplicate the |
| Swashes | Add .swsh to the glyph name. |
| Titling | Add .titl to the glyph name. |
| Initial Forms | Add .init to the glyph name. |
| Medial Forms | Add .medi to the glyph name. |
| Medial Forms | Add .med2 to the glyph name. Used only with the Syriac script. |
| Terminal Forms | Add .fina to the glyph name. |
| Terminal Forms | Add .fin2 to the glyph name. Used only with the Syriac script. |
| Terminal Forms | Add .fin3 to the glyph name. Used only with the Syriac script |
| Full Widths | Add .full or .fullwidth to the glyph name, and emspace will substitute space. |
| Horizontal Kana Alternates | Add .hori to a Katakana or Hiragana glyph name. |
| Hojo Kanji Forms | Add .hojo to the glyph name. Use it for JIS X 0212–1990 Kanji Forms. The respective unsuffixed default glyphs should be JIS X 0213: 2004 shapes. |
| Half Widths | Add .half to the glyph name, end enspace will substitute space. |
| Italics | Add .italic to the glyph name. |
| Proportional Kana | Add .proportional to a Katakana or Hiragana glyph name. |
| Proportional Widths | Add .proportional to the glyph name. |
| Quarter Widths | Add .qartwidth to the glyph name. |
| Ruby Notation Forms | Add .ruby to the glyph name. |
| Third Widths | Add .thirdwidth to the glyph name. |
| Vertical Kana Alternates | Add .vert to a Katakana or Hiragana glyph name. |
| Vertical Alternates and Rotation | Add .vert to the glyph name. |
| Above-base Substitutions | Triggered by certain base and mark combinations in South Asian scripts. |
| Akhands | Triggered by a number of letter and ligature glyphs in South Asian scripts. |
| Below Base Forms | Triggered by halants and .below glyphs in combination with a range of other glyphs in South Asian scripts. |
| Below-base Substitutions | Triggered by certain letter combinations in South Asian scripts, such as Gujarati letters with a .straight suffix or specific halant combinations in Oriya. |
| Conjunct Forms | Triggered by conjunct clusters in South Asian scripts. |
| Half Forms | Triggered by half-form glyphs ending in Halfform in conjunction with halant in South Asian scripts. |
| Nukta Forms | Triggered by nukta ligatures ending in Nukta and the script abbreviation, in conjunction with the same glyphs without nukta, in South Asian scripts. |
| Pre-base Forms | Triggered by a halant in certain letter constellations in South and Southeast Asian scripts. |
| Pre-base Substitutions | Triggered by certain matra and conjunct constellations in South Asian scripts. Define width variants with number suffixes, for example, iMatra-deva.01 through iMatra-deva.20, and the feature generator will pick the appropriate width variant for each conjunct. |
| Post-base Substitutions | Triggered by a halant glyph in combination with script-specific base and matra constellations, such as eMatra-kannada with .base and .base.e glyphs in Kannada. Applies to South Asian scripts only. |
| Rakar Forms | Triggered by rakar ligatures in conjunction with the isolated glyphs and halant in Devanagari, Gujarati, and Malayalam. |
| Reph Forms | Triggered by ra-deva, halant-deva and reph-deva, or an analogous glyph structure in other South Asian scripts. |
| Vattu Variants | Triggered by the presence of specific lookups in the |
| Glyph Composition and Decomposition | A wide range of glyph constellations in various scripts will trigger the automatic creation of |
| Mark to Base Positioning | Add anchors without underscores to base letters, like top or bottom, and add combining marks (for example, acutecomb) with underscore anchors (for example, _top or _bottom) to glyphs in the font.
Their width is automatically set to zero at export.
