From 6128bef38acc2889155706b81bc041e5a990fdf7 Mon Sep 17 00:00:00 2001 From: Matt Van Horn <455140+mvanhorn@users.noreply.github.com> Date: Fri, 20 Mar 2026 21:13:39 -0700 Subject: [PATCH] feat(cli): add `specify extension init` scaffolding command Add a new `specify extension init ` subcommand that scaffolds a ready-to-develop extension directory from the built-in template. Substitutes extension metadata (ID, name, author, description, repository URL, date) into all template files. The extension ecosystem has 23+ community extensions, all manually created by copying extensions/template/. This command completes the extension authoring lifecycle - every other stage (search, add, remove, enable, disable, update, catalog management) already has CLI support. Features: - Extension ID validation (lowercase, hyphen-separated) - Interactive prompts when CLI args are omitted - --output flag for custom output directory - --no-git flag to skip git initialization - Replaces EXAMPLE-README.md as the new README.md - Prints next-steps guidance panel Includes 23 pytest test cases covering validation, placeholder substitution, CLI integration, and edge cases. --- src/specify_cli/__init__.py | 171 +++++++++++++++++++++++++ tests/test_extension_init.py | 234 +++++++++++++++++++++++++++++++++++ 2 files changed, 405 insertions(+) create mode 100644 tests/test_extension_init.py diff --git a/src/specify_cli/__init__.py b/src/specify_cli/__init__.py index d2bf63eeb..f348c1887 100644 --- a/src/specify_cli/__init__.py +++ b/src/specify_cli/__init__.py @@ -4416,6 +4416,177 @@ def extension_set_priority( console.print("\n[dim]Lower priority = higher precedence in template resolution[/dim]") +def _validate_extension_id(name: str) -> bool: + """Validate extension ID: lowercase, hyphen-separated, alphanumeric.""" + import re + return bool(re.match(r'^[a-z][a-z0-9]*(-[a-z0-9]+)*$', name)) + + +def _title_case_extension(name: str) -> str: + """Convert hyphen-separated extension ID to title case display name.""" + return " ".join(word.capitalize() for word in name.split("-")) + + +def _find_extension_template() -> Optional[Path]: + """Locate the bundled extension template directory. + + Checks for the template embedded in the installed package first, + then falls back to the source tree layout. + """ + #
