Glyph can push a clean public projection to GitHub through an export-only remote. 
glyph remote add origin github:OWNER/REPO --mode export-only --json
glyph remote sync origin --json
For this repository, GitHub is an export-only mirror: 
github:Illusion47586/glyph
The sync process:
  1. materializes the public realm
  2. initializes a clean Git repository
  3. generates compatibility files from glyph.yaml
  4. preserves the previous remote main commit as parent when present
  5. pushes to GitHub
The .glyph/ directory itself is never pushed.

Manual Git Export

Use glyph export git when you want a local Git repository without pushing it. 
glyph export git \
  --realm public \
  --out .glyph/exports/origin \
  --gitignore generated \
  --gitinclude generated \
  --json
Flags:
FlagMeaning
--realmRealm to export. Defaults to public.
--outOutput directory. Required.
--gitignoreControls .gitignore generation: none, generated, or overwrite.
--gitincludeControls .gitinclude generation: none, generated, or overwrite.
If the flags are omitted, Glyph reads defaults from glyph.yaml.

​
Remote Management

glyph remote list --json
glyph remote inspect origin --json
glyph remote sync origin --json
Remote specs can use the GitHub shorthand: 
github:OWNER/REPO
Glyph translates that to the SSH URL git@github.com:OWNER/REPO.git during sync.

​
Compatibility Files

Glyph can generate .gitignore and .gitinclude from the project policy in glyph.yaml. The default for this project is: 
defaults:
  export:
    git:
      gitignore: generated
      gitinclude: generated
Use generated to create a file only when it does not already exist, overwrite to replace it, and none to skip generation.
