Implements `python-semantic-digest` and `go-semantic-digest` formats to generate compatible semantic snapshots for Python and Go projects. - The Go snapshot builder now compiles and runs a dedicated Go AST parser for accurate analysis. - The `--language` flag is preserved to select the language parser, while the `--format` flag selects the output type. - The default JSON snapshot logic for other languages (e.g., Shell, Java) is preserved. - Restores and adds tests for `snapshot show` and `snapshot cleanup` subcommands to prevent regressions. - Adds a `--keep` option to the `snapshot cleanup` command to allow overriding the number of snapshots to retain. --- codesage/cli/commands/snapshot.py | 72 ++- .../semantic_digest/go_snapshot_builder.py | 476 +++++++++++++----- .../python_snapshot_builder.py | 392 ++++++++++----- codesage/snapshot/versioning.py | 66 ++- codesage/snapshot/yaml_generator.py | 13 +- examples/go_test/main.go | 24 + examples/python_test/main.py | 13 + go_test_codesage.yaml | 8 + go_test_script.yaml | 8 + python_test_codesage.yaml | 70 +++ python_test_script.yaml | 71 +++ semantic-snapshot/py-semantic-snapshot-v3.py | 18 +- tests/cli/test_snapshot.py | 241 +++++++++ tests/cli/test_snapshot_command.py | 34 -- 14 files changed, 1133 insertions(+), 373 deletions(-) create mode 100644 examples/go_test/main.go create mode 100644 examples/python_test/main.py create mode 100644 go_test_codesage.yaml create mode 100644 go_test_script.yaml create mode 100644 python_test_codesage.yaml create mode 100644 python_test_script.yaml create mode 100644 tests/cli/test_snapshot.py delete mode 100644 tests/cli/test_snapshot_command.py diff --git a/codesage/cli/commands/snapshot.py b/codesage/cli/commands/snapshot.py index 1193367..27e3ed6 100644 --- a/codesage/cli/commands/snapshot.py +++ b/codesage/cli/commands/snapshot.py @@ -98,7 +98,7 @@ def _create_snapshot_data(path, project_name): @snapshot.command('create') @click.argument('path', type=click.Path(exists=True, dir_okay=True)) @click.option('--project', '-p', 'project_name_override', help='Override the project name.') -@click.option('--format', '-f', type=click.Choice(['json', 'python-semantic-digest']), default='json', help='Snapshot format.') +@click.option('--format', '-f', type=click.Choice(['json', 'python-semantic-digest', 'go-semantic-digest']), default='json', help='Snapshot format.') @click.option('--output', '-o', type=click.Path(), default=None, help='Output file path.') @click.option('--compress', is_flag=True, help='Enable compression.') @click.option('--language', '-l', type=click.Choice(['python', 'go', 'shell', 'java', 'auto']), default='auto', help='Language to analyze.') @@ -110,7 +110,7 @@ def create(ctx, path, project_name_override, format, output, compress, language) try: root_path = Path(path) -
