Highlights

• Split backend implementation into dedicated files:
  • ast-grep-core.el
  • ast-grep-sync.el
  • ast-grep-consult.el
  • ast-grep-ivy.el
• Added ast-grep-search-backend to choose between auto, sync, consult, and ivy.
• Added ast-grep-describe-backend to show the configured and resolved backend.
• Added Eask-based test sandboxes for sync, consult, ivy, and full backend coverage.

Backend Behavior

• auto uses counsel/ivy when ivy-mode is active and ivy/counsel are available.
• Otherwise, auto uses consult when available.
• Falls back to synchronous completing-read when async backends are unavailable.
• Consult backend is tested on Emacs 29+.
• Sync and ivy remain available on Emacs 28.1+.

Ivy Fixes

• Fixed ivy/counsel async results not appearing in the candidate list.
• Fixed ivy live preview support.
• Ensured the ivy backend uses counsel's default async process lifecycle.
• Added real counsel/ivy sandbox tests so ivy support is actually load-bearing.

Testing and CI

• Added Eask.
• Added backend-specific commands:
  • eask run script test:sync
  • eask run script test:consult
  • eask run script test:ivy
  • eask run script test:full
• Updated GitHub Actions to run backend-specific matrices across supported Emacs versions.

Notes

No configuration change is required for existing users. The default backend remains auto.
