The repository, commit and config are recorded in the `source { }` block of METADATA.pb and are not duplicated here. -**Glass Antiqua** is a display/handwriting serif font designed by Denis Masharov, added to Google Fonts on 2012-02-22. It is a revival of the 1913 typeface "Glass Antiqua" by Genzsch & Heyse. The upstream repository is `librefonts/glassantiqua` on GitHub, a mirror repo created by hash3g in October 2014. The repo contains decomposed TTX files alongside legacy source formats (SFD and VFB). There are no gftools-builder-compatible sources and no config.yaml. The font binary in google/fonts has not been modified since the initial commit. +## Initial state -## Key Findings +The upstream repository shipped only FontForge `.sfd` sources and had no gftools-builder configuration. METADATA.pb pointed at the librefonts mirror with an onboarding commit but no `config_yaml`, so the family could not be rebuilt with the current Google Fonts pipeline. -| Field | Value | -|--------------------|--------------------------------------------------------------------| -| Family Name | Glass Antiqua | -| Designer | Denis Masharov | -| Repository URL | https://github.com/librefonts/glassantiqua | -| Commit Hash | ccc1839b05e9827b7f3a1439d089952908cd0334 | -| Config YAML | None (SFD-only sources) | -| Status | no_config_possible | -| Confidence | HIGH | -| License | OFL | -| Date Added | 2012-02-22 | -| Category | DISPLAY | +## Actions taken -## Investigation Details +The single FontForge source `src/GlassAntiqua-Regular-TTF.sfd` was converted to Glyphs with babelfont-rs (upstream commit `219c0bb`), producing `sources/GlassAntiqua-Regular.glyphs`. A gftools-builder configuration was added and the repository was restructured to the Unified Font Repository template. The superseded `.sfd` sources and legacy build cruft were retired. No further source corrections were required beyond the conversion. -### METADATA.pb Analysis +## Final state -The current METADATA.pb at `ofl/glassantiqua/METADATA.pb` contains basic metadata plus stroke/classifications fields. Originally it had no source block. A source block was added in commit `9a14639f3c` (2026-02-25) with the repository URL and commit hash. +The repository builds `GlassAntiqua-Regular.ttf` from the converted `.glyphs` source through gftools-builder3 and fontc. -### Google Fonts Git History +## Verification -The font file `GlassAntiqua-Regular.ttf` was added in the initial commit of the google/fonts repository: +The freshly built binary was compared against the shipped `GlassAntiqua-Regular.ttf`. The verdict was FUNCTIONAL: character coverage, metrics and outlines matched. The only difference was that 15 glyphs were renamed to their standard production names; the set of encoded characters is unchanged, so the rename is cosmetic and does not affect rendering. -- **Commit**: `90abd17b4f97671435798b6147b698aa9087612f` (2015-03-07, Dave Crossland, "Initial commit") -- The font binary has not been modified since then. -- Subsequent commits touched METADATA files only: METADATA.json to METADATA.pb conversion, language support metadata, stroke and classifications additions, HTML formatting. -- **Commit `47a6c224b3`** (2023-08-08, Evan Adams): Added `stroke: "SERIF"` and `classifications: "HANDWRITING"` to METADATA.pb. +## Original repository (dormant) -A deploy commit (`76adaf1d2`, 2021-11-01, m4rc1e) deleted the files, but this commit is not on the main branch -- it was part of an orphan/dead branch. The main branch retains the original font file from the initial commit. - -### Upstream Repository Analysis - -**Repository**: https://github.com/librefonts/glassantiqua -**Cached at**: `upstream_repos/fontc_crater_cache/librefonts/glassantiqua` -**GitHub status**: Accessible (HTTP 200) - -The repository is a shallow clone containing a single visible commit: -- **Commit**: `ccc1839b05e9827b7f3a1439d089952908cd0334` (2014-10-17, hash3g, "update .travis.yml") - -This is a `librefonts` organization mirror -- these repos were created by hash3g as part of a systematic effort to create GitHub mirrors of Google Fonts families with decomposed TTX data and CI configuration. - -### Source Files - -The repository contains: -- **`src/GlassAntiqua-Regular-TTF.sfd`** -- FontForge SFD source (TTF outlines) -- **`src/GlassAntiqua-Regular-OTF.vfb`** -- FontLab VFB source (binary, proprietary format) -- **`src/GlassAntiqua-Regular.otf.*.ttx`** -- Decomposed OTF TTX tables (including kern table) -- **Root-level `GlassAntiqua-Regular.ttf.*.ttx`** -- Decomposed TTF TTX tables (including GPOS, GDEF, GSUB, DSIG) -- **`src/GlassAntiqua-A.jpg`**, **`src/GlassAntiqua-B.jpg`** -- Reference images (likely scans of original 1913 typeface) -- **`.travis.yml`** -- Travis CI config using fontbakery-build.py -- **`src/VERSIONS.txt`** -- "GlassAntiqua-Regular.ttf: 1.001" - -**No gftools-builder-compatible sources** (.glyphs, .ufo, .designspace) exist. The only editable sources are SFD (FontForge) and VFB (FontLab), neither of which is supported by gftools-builder/fontc. - -### Config YAML Assessment - -No config.yaml exists and none can be created because: -1. There are no .glyphs, .ufo, or .designspace source files -2. SFD and VFB formats are not supported by gftools-builder -3. The TTX files are decomposed table dumps, not proper build sources - -### Notable Details - -- The font is a revival of a historical typeface ("Glass Antiqua" by Genzsch & Heyse, 1913), found in the Taschen book "Type: A Visual History of Typefaces and Graphic Styles, 1901-1938." -- The src/ directory contains two JPG reference images, likely scans from the original specimen. -- The font has both SERIF stroke and HANDWRITING classification, reflecting its hybrid nature (slab serif + antiqua + cursive calligraphy elements). - -## Conclusion - -The source block in METADATA.pb is correct. The librefonts mirror is the only known upstream repository. The font sources are SFD/VFB only, making a gftools-builder config.yaml impossible. - -### Recommended METADATA.pb Source Block - -``` -source { - repository_url: "https://github.com/librefonts/glassantiqua" - commit: "ccc1839b05e9827b7f3a1439d089952908cd0334" -} -``` - -**Status**: `no_config_possible` -- SFD/VFB-only sources are not compatible with gftools-builder. +The original sources lived at https://github.com/librefonts/glassantiqua, whose latest commit was `ccc1839b05e9827b7f3a1439d089952908cd0334` on the `master` branch.
